Impact of mass flow rate monitoring and control in continuous tablet manufacturing

Research categories:  Chemical
School/Dept.: Chemical Engineering
Professor: Gintaras Reklaitis
Preferred major(s): chemical engineering
Desired experience:   completion of ChE 37700, ChE 32000
Number of positions: 1

The pharmaceutical tablet manufacturing process involves particulate handling and processing. Measurement and control of particulate material properties and the process variables of the constituent unit operations in continuous flow is a challenge for the effective implementation of real time product release. The tablet hardness and weight have to be maintained at the desired throughput and it is essential to determine the appropriate hopper levels at steady state to ensure seamless operation. The aim of the project is to study the effect of hopper level on the quality of the tablets and the effect on different process variables of the tablet press. The undergraduate student in this project will learn techniques used in the characterization of particulate material and tablets in the continuous tableting line.

Project Description
In the past decade, changes in domestic/global market growth, desire for new drug therapies (with faster time to market), and pressure to minimize drug cost in healthcare expenditure have prompted revision of operational strategies/technologies in the pharmaceutical industry. Concomitant with improvement to current technologies, there has been interest in development of novel methods for drug product manufacture; additive manufacturing (of which 3-dimensional printing is a subset), has received considerable attention, due in part to the precision afforded the user by the process’s incremental production method. In our lab we have ongoing work which furthers the development of process modeling and monitoring capabilities for a dropwise pharmaceutical manufacturing technology capable of processing non-colloidal suspensions. The interested student would be engaged at drug product manufacture and in the characterization of the resulting dosages. Specifically this would involve printing and characterization of drug products from 4 new “micronized” active pharmaceutical drug powders.

Biosensors for point-of-care applications

Research categories:  Bioscience/Biomedical, Chemical, Life Science
School/Dept.: Chemical Engineering
Professor: Chongli Yuan
Preferred major(s): Chemical Engineering/Biomedical Engineering
Number of positions: 1

The large number of people affected by infectious diseases in the developing world puts an enormous burden on the health system. Infected patients, which now have global access to therapies, require constant disease management and regular visits to clinics. This burden creates a great challenge in low-resource areas with a limited number of trained medical personnel and constrained diagnostic and monitoring methods. A consequence of such limited resources and restricted monitoring of therapy is the development of drug resistance, a major hurdle to patient care worldwide. A point-of-care tool that enables rapid detection of drug resistance mutations is of pressing need to meet the increasing health-care demand in developing countries. This application thus aims to develop a cellphone-based detection device for drug resistance.

Cylindrical shells based phase transforming cellular materials

Research categories:  Aerospace Engineering, Civil and Construction, Mechanical Systems
School/Dept.: Lyles School of Civil Engineering
Professor: Pablo Zavattieri
Preferred major(s): Civil, ME, AAE Engineering
Desired experience:   Mechanics of Materials and Structures, CAD, Matlab/Phyton/C (some coding required)
Number of positions: 1

Active materials like shape memory, ferroelectric and magnetostrictive alloys obtain their characteristic properties due to phase transformations. In these materials, phase transformations occur by changing the packing arrangement of the atoms in a process that resembles multistable mechanisms switching between stable configurations. A similar behavior has been observed in folded proteins in which a change in configuration (e.g. from folded to unfolded) provides the mechanism through which biological materials obtain remarkable properties such as combinations of strength and toughness, superelasticity and shock energy dissipation, among others. Phase transformations can be extended to cellular materials by introducing materials whose unit cells have multiple stable configurations. Each stable configuration of the unit cell corresponds to a phase, and transitions between these phases are interpreted as phase transformations for the material. It has been demonstrated that phase transforming cellular materials (PXCMs) offer innovative advantages for energy dissipation without relying in the inelastic behavior of its base material making PXCMs attractive for many applications like: automobiles, protective gear, or buildings.

In this project we propose to develop a new type of PXCMs based on cylindrical shells. The new PXCMs will be designed using computer-aided design (CAD) modeling software and fabricated using a 3D printer in combination with other fabrication techniques. Compression and tension tests will be conducted on testing machines to evaluate the performance of these new PXCMs. The test results will then be analyzed using scripts in any number of computer languages (e.g. MATLAB, Python, or C).

Dual-tuned traps for common-mode current suppression in multi-nuclear MRI hardware cabling

Research categories:  Bioscience/Biomedical, Electronics, Mechanical Systems
School/Dept.: Weldon School of Biomedical Engineering
Professor: Joseph Rispoli
Preferred major(s): Biomedical Engineering, Electrical Engineering, or Mechanical Engineering
Desired experience:   CAD modeling, proficiency with hand tools and soldering, and a general understanding of AC circuits
Number of positions: 1

The research is important for conducting multi-nuclear magnetic resonance imaging experiments on humans, e.g., obtaining sodium MRI visualizations of the brain in addition to typical hydrogen-based MRI. The goal is to produce a prototype device that may be reproduced and used in multiple experiments, publish a paper demonstrating the results, and the design potentially may be adopted at other medical research sites.

The student would be tasked to design a removable cable trap to suppress common mode currents at two different radio frequencies. Common mode currents are those induced on the outside of a coaxial cable's shield, are not part of the desired MRI signal, and in some situations have caused injury to MRI subjects who were mistakenly in contact with the cable while scanning.

Execution of the project will require prototyping of a simple electrical circuit, and as such will require some work with wire, cable, electrical components, and soldering. However the greater challenge may be the mechanical design of the circuit, given the geometry will affect the operation and the device must easily be clipped on and off cables.

The student is expected to lead this project, under the guidance of a graduate student and faculty member. The student is also expected to prepare a poster presentation on the results, and author a research paper if the desired results are achieved.

 

Extraterrestrial Habitat Engineering

Research categories:  Aerospace Engineering, Civil and Construction, Mechanical Systems, Other
School/Dept.: ME and CE
Professor: Shirley Dyke
Preferred major(s): CE, ME, AAE or Planetary Science
Number of positions: 1-2

There is growing interest from Space agencies such as NASA and the European Space Agency in establishing permanent human settlements outside Earth. However, even a very cursory inspection of the proposals uncovers fatal flaws in their conceptual design. The buildings may not be able to support the load demands, which should include potential impact from meteorites and/or the seismic motions induced by such an impact, and perhaps most importantly, the materials used as cover for radiation protection may be radioactive themselves. Ongoing research interest focuses on mitigating astronauts' health and performance in space exploration and has neglected the largely unexplored needs regarding the habitat and infrastructure required on extraterrestrial bodies. Their design and sustainability represents a multidisciplinary engineering and scientific challenge for humanity. In a context of extreme environments, it is especially important to design buildings whether for habitation, laboratory or manufacturing, that are capable of responding to prevailing conditions not only as a protective measure, but also to enable future generations to thrive under such conditions.

Participating undergraduate researchers would be tasked to design and develop the following areas:
- design and build a prototype habitat for a permanent human settlement on the Moon as a preliminary proof of concept.
- develop concept experiments to assess critical issues such as the challenge of pressurizing rock openings or for a cavern to survive a meteorite impact.

Construction, assembly and experimentation will be done in the laboratory, using Purdue's expertise in the emerging field of real-time hybrid simulation (RTHS). RTHS uses sub-structuring, feedback control and real-time parallel computing to break a complex system into several computational and physical subsystems, realistically allowing testing of systems that are too large to fit in a laboratory.

We are looking for students to play key roles in this project, under the guidance of a graduate student and faculty members. The students are also expected to prepare a poster presentation on the results, and author a research paper if the desired results are achieved.

 

Fluid Dynamics of Bacterial Aggregation and Formation of Biofilm Streamers

Research categories:  Bioscience/Biomedical, Chemical, Computational/Mathematical, Physical Science
School/Dept.: Mechanical Engineering
Professor: Arezoo Ardekani
Number of positions: 1

Bacteria primarily live within microscopic colonies embedded inside a self-secreted matrix of polymers and proteins. These microbial biofilms form on natural and man-made surfaces and interfaces and play important roles in various health and environmental issues. Previous experimental studies have indicated the significance of bacterial motility mechanisms in the colonization process and the subsequent biofilm formation. In particular, flagellar mediated swimming is crucial in approaching the surface and initiating the adhesion process. Understanding the swimming strategy of bacteria in confined geometries is shown to be a decisive factor in identifying the adhesion rate and elucidating the subsequent colonization process. However, majority of studies focused on the swimming behavior of motile cells in complex fluids have been conducted assuming the cells’ habitat to be an unbounded domain and thus, the boundary induced effects, such as surface trapping and wall accumulation, are poorly understood. The student will investigate the motion of microorganisms in complex fluids near boundaries.

The research we do is building relationships between the material's microstructure and the subsequent performance of the material, in terms of fatigue, fracture, creep, delamination, corrosion, plasticity, etc. The majority of our group’s work has been on advanced alloys and composites. Both material systems have direct applications in Aerospace Engineering, as we work closely with these industries.

We are looking for a motivated, hard-working student interested in research within the field of experimental mechanics of materials. The in situ experiments include advanced materials testing, using state-of-the-art 3d strain mapping. We deposit self-assembled sub-micron particles on the material’s surface and track their displacement as we deform the specimen. Coupled with characterization of the materials microstructure, we can obtain strain localization as a precursor to failure. Specific projects look at increasing the structural integrity of additive manufactured materials and increasing fidelity of lifing analysis to introduce new light weight materials into applications.

School/Dept.: Mechanical Engineering
Professor: David Cappelleri
Preferred major(s): Mechanical Engineering / Electrical & Computer Engineering
Desired experience:   Must be US citizen for this project. ME students should have programming and electronics experience.
Number of positions: 1

Mobile microrobots offer unprecedented capabilities for observing and interacting with the world that are not possible with conventional macro-scale systems. A critical issue in the design of mobile microrobots is the generation of wireless power and methods of converting that power into locomotion. We have successfully used externally applied magnetic fields for the power and actuation of individual magnetic mobile microrobots. We have also come up with novel tumbling microrobot designs to overcome the challenge of large surface forces at the micro-scale. In the case of multiple microrobots, all the robots in the workspace will be exposed to identical control signals. Thus, in order to achieve different behaviors from individual robots needed for advanced manufacturing tasks, there must be either significant variation in their design or in the magnetic control signals applied to each microrobot. Therefore, we are have also created a specialized control substrate for local targeting of the magnetic forces at a fine resolution to be able to independently control multiple microrobots at the same time.

In this project, the SURF student will work with graduate students and a post-doc to design and test new mobile microrobot designs with various in-house magnetic manipulation systems for advanced manufacturing and biomedical applications. The student should be proficient in C-based language programming, Matlab, image processing, hardware interfacing, and 3D printing.

Project Description
Continuous manufacturing and on-line process monitoring have the potential to improve product quality in the Pharmaceutical Industry [1]. In 2002 the FDA initiated Quality-by-Design (QbD) through Process Analytical Technology (PAT) tools. The goal of PAT is to augment the understanding and control the manufacturing process [2,3]. Through the implementation of QbD and PAT, the companies have to demonstrate understanding of how the operating conditions, process design and raw material variability affect the product quality [4].
On-line measurement of process conditions plays a significant role in continuous manufacturing implementation and its understanding. However, every measurement is subject to error. Therefore, having measurement redundancy and selecting the appropriate Critical Quality Attributes (CQAs) to measure are crucial steps in developing an effective system for process monitoring. It is by implementing appropriate sensors that we can obtain a better estimate of the actual state of the process. The objective of this project is to test different sensor network configuration and investigate the effect of each measurement in improving the values of process variables of our continuous tableting line.

Structural Stability of Cylindrical Steel Storage Tanks

Cylindrical steel storage tanks are essential parts of infrastructure and industrial facilities used to store liquids and granular bulk solids. There are many procedures given in design standards to withstand the possible load effects, such as the hydrostatic pressure of the stored liquid, the external wind pressure, internal and external pressures due to process, and seismic events. Failure of a tank may cause catastrophic consequences.

The internal hydrostatic pressure due to the stored liquid results in tensile circumferential stress in the steel plates forming the shell. Because the resultant circumferential stress is tension and not compression, the yielding and tensile rupture criteria are the main concern. Analysis and design principles to account tensile stresses due to hydrostatic pressure is well established (Azzuni and Guzey 2015).

External wind pressure is also a load effect for the design of cylindrical storage tanks. When a tank is empty, it is vulnerable to buckling due to external wind pressure. This buckling failure mode is addressed by increasing the overall stiffness of the structure by adding stiffener rings to the shell. However, current design specifications in North America and Europe are overly conservative for the sizing of the stiffener rings (Godoy, 2016). The current design rules for sizing the top stiffener ring is based on intuition and experience. Although some researchers suggested some analytical justifications (Adams, 1975), these justifications are based on a number of assumptions which are based on the yielding criteria of the stiffener ring and not the buckling criteria.

In this study we shall investigate analytical, semi-analytical and computational procedures to obtain a more robust and resilient design of cylindrical storage tanks due to external wind loading. We shall use classical thin shell theory to obtain an upper bound buckling capacity of cylindrical tanks under wind loading. We shall use Raleigh-Ritz methods to obtain a simple semi-analytical buckling expressions. In addition, we shall investigate the storage tanks using finite element analysis with the use of geometrically nonlinear analysis including imperfections (GNIA). With the GNIA we shall establish a lower bound buckling capacity of these tanks. Finally, we shall compare our results with the available experimental physical testing of the cylindrical tanks and suggest a new design procedure. The undergraduate SURF student will work under the mentorship of Dr. Guzey and a graduate student. The SURF student compile a literature review, perform numerical simulations using FEA computer program ABAQUS, and write scientific research papers and conference presentations.

Synthesis, Characterization, and Reactivity of Low-Valent Uranium Species

Research categories:  Chemical
School/Dept.: Department of Chemistry
Professor: Suzanne Bart
Preferred major(s): Chemistry
Desired experience:   General Chemistry and Organic Chemistry lab courses completed
Number of positions: 1

Understanding of the fundamental chemistry of transition metal alkyl species has contributed greatly to the advancement of pharmaceuticals, materials, and fine chemicals. Comparatively we know much less about the types of reactions of which the f-block elements, more specifically uranium, are capable. The principal investigator’s laboratory is working to understand the synthesis, characterization, and reactivity of reduced uranium complexes for small molecule activation. Our initial findings have led us to understand the great chemical potential of uranium(III) and uranium(IV) alkyls and taught us how to effectively work with this electron rich metal, avoiding decomposition and disproportionation observed by others. Future work, proposed here, explores the hypothesis that low-valent uranium alkyls are useful synthons for elusive uranium targets. Experiments will be carried out to 1) obtain a family of uranium(III) alkyls with a variety of ancillary ligands, 2) understand under what conditions uranium can undergo two electron processes, similar to late transition metals, including reductive elimination, oxidative addition, and migratory insertion, 3) explore the utility of uranium alkyls for multiple bond formation. The work proposed here includes synthetic methods, spectroscopic analysis, and computational approaches to fully understand the reactivity of these compounds.

Although an underutilized element, uranium has many positive traits that make it suitable for metal mediated transformations. The principle investigator’s laboratory is studying how to control chemical reactivity at low- and mid-valent uranium centers in solution. These studies encompass understanding the stability and reactivity of organouranium species to determine their potential for new transformations. Efforts towards understanding how to make uranium perform two electron processes are also underway. Characterization of our uranium complexes through spectroscopic and computational methods will provide insight into uranium-element bonding. Uranium has been demonstrated to perform reactions unparalleled by transition metals, and there is no doubt that more exciting processes mediated by uranium will be uncovered.

This study will determine the involvement of HSP in postmortem protein degradation of beef and/or pork muscles. Student will have hands-on experience by performing assays to observe and quantifying the presence of small heat shock proteins present in samples, and interpreting results. Student will assist graduate students in any way needed, especially as is relevant to studies in small heat shock proteins.

 

Thermodynamics of Coherent Structures near Phase Transitions

School/Dept.: Mechanical Engineering
Professor: Ivan Christov
Preferred major(s): Engineering, Physics or Mathematics (any subareas of each)
Desired experience:   Knowledge of programming in MATLAB and/or a MATLAB-like high-level language (such as python). Experience writing own computer code and analyzing the numerical output. Basic understanding of partial differential equations. Basic understanding of thermodynamics and classical physics.
Number of positions: 1

Many phenomena in physics, engineering and material science can be addressed by "simple" mathematical models capturing only the essential behavior. Coherent structures are common to all areas of science, from synchronized oscillations of fireflies to Jupiter's red spot. "Simple" (also called phenomenological) models of phase transitions (abrupt changes in system behavior) also exhibit coherent structures and self-organized behavior. When large numbers of coherent structures interact in the presence of noise and/or external driving forces, a thermodynamic limit can be taken, describing the complex system by a single nonlinear partial differential equation for the "field" of coherent structures.

This project is aimed at numerically confirming analytical results obtained recently about such systems. The SURF student will work with the faculty member to further develop simple numerical simulations of partial differential equations using standard software such a MATLAB or Python tools such as numpy and scipy. The SURF student will generate simulations spanning a large parameter space and of sufficient size and accuracy to compute long-time (thermodynamic) averages suitable for comparison to the theory. If successful, the theory-numerics comparison will yield an important journal publication.

Wideband GNSS Reflectometry Instrument Design and Signal Processing for Airborne Remote Sensing of Ocean Winds.

Research categories:  Aerospace Engineering, Computer Engineering and Computer Science, Electronics, Environmental Science, Physical Science, Other
School/Dept.: AAE
Professor: James Garrison
Preferred major(s): Electrical Engineering, Physics
Desired experience:   Linear Systems, Signal processing, computer programming (C, Python, MATLAB). Some experience building computers or electronics is desirable. A basic understanding of electromagnetism is also desirable.
Number of positions: 1

This research project will involve the assembly and test a remote sensing instrument to make measurements of the ocean wind field from the NOAA “Hurricane Hunter” aircraft. The fundamental operating principle of this new instrument is “reflectometry”, which is based upon observing changes in the structure of a radio frequency signal reflected from the ocean surface. These changes are related to the air-sea interaction process on the ocean surface and can be used to estimate the wind speed through empirical models. Transmissions from the Global Navigation Satellite System (GNSS), (e.g. GPS, Galileo, Glonass or Compass) are ideal signal sources for reflectometry, due to their use of a “pseudorandom noise” (RRN) code.

NASA will be launching the CYGNSS satellite constellation in November to globally monitor the tropical ocean and observe the formation of severe storms. CYGNSS will use a first generation GNSS-R instrument. This summer research project will produce a next-generation prototype taking advantage of the wider bandwidth of the Galileo E5 signal (~90 MHz vs. 2 MHz) for higher resolution measurements of the reflected signal.

In addition to hardware assembly and testing in the laboratory, this research project will also require the development of signal processing algorithms to extract essential information from the scattered signal. A “software defined radio” approach will be used, in which the full spectrum of the reflected signal is recorded and post-processed using software to implement the complete signal processing chain.

The goal of this summer research project is to deliver a working instrument, post processing software, and documentation to NOAA for flight on the hurricane aircraft during the 2017 hurricane season. There are two objectives of this experiment. The first is to demonstrate the feasibility of wideband E5 reflectometry measurements. The second objective is to collect the highest quality GNSS reflectometry data, under a wide variety of extreme meteorological conditions, to improve the empirical models that will be used for processing CYGNSS data and generating hurricane forecasts.

Students interested in this project should have good programming skills and some experience with C, Python and MATLAB. They should also have a strong background in basic signal processing. Experience with building computers or other electronic equipment will also be an advantage.

Millions of network cameras have been deployed worldwide and they can continuously stream live video to anyone connected to the Internet (without any password). These cameras may be deployed in shopping malls, city centers, university campuses, street intersections, etc. Through these cameras, it is possible to understand and study Social interactions, Behaviors, and Economic activities (SBE) in different parts of the world and to compare the influence of cultures, environments, geographical locations, time, and so on. However, the vast amounts of data must be properly managed so that valuable information can be extracted. The purpose of this project is to create computer tools that can facilitate discovery of patterns of human behaviors from worldwide network cameras.

This project has four major parts: (1) discovering the network cameras that can provide data relevant to SBE research, (2) retrieving, saving, and organizing data from these cameras, (3) providing user interfaces for SBE researchers to visualize the data and observe behaviors, and (4) developing computer vision solutions to automatically understand human behaviors.
