Project Name: Nanoscale 3D printing Project ID: R003
Supervisor: Xianfan Xu Number of Positions Up to 2
Project Description: The ability to create 3D structures in the micro and nanoscale is important for many applications including electronics, microfluidics, and tissue engineering. This project deals with development and testing of a setup for building 3D structures using a femtosecond pulsed laser. A method known as two photon polymerization is used to fabricate such structures in which a polymer is exposed to laser and at the point of the exposure the polymer changes its structure. Moving the laser in a predefined path results in the desired shape and the structures. The setup incorporates the steps from designing a CAD model file to slicing the model in layers to generating the motion path of the laser needed for fabricating the structure. Possible improvements to the process by the undergraduate researcher include control algorithms, better CAD models, and better manufacturing strategies.

Project Name: Mechanical and chemical stability atomic force microscopy tips
Project ID: R015
Supervisor: Ryan Wagner Number of Positions 1
Project Description: Atomic force microscopy (AFM) is an important scientific tool in many research areas ranging from nanotechnology, material science, and biology. It is used in diverse applications such as atomic resolution imaging of crystalline lattices, mapping doping concentration of transistors, and measuring the mechanical properties of living cells. An AFM utilizes a sharp tip mounted on the end of a silicon microcantilever. To make meaningful measurements the tip shape and tip surface cannot change during the measurement period. This stability is difficult to achieve for two reasons. First, due to the small contact area between the tip and surface, stress in the tip tends to be high. Second, material from the surface can stick to the tip. The proposed research will seek to develop a broadly useable metric for characterizing the stability of an AFM tip. Potential metrics include monitoring the resonance frequency of the cantilever or characterizing an aspect of the interaction between the tip and the surface.
Final Deliverables: Report and/or a scientific paper detailing and demonstrating the developed AFM tip stability metric

Desired Qualifications Junior or senior standing, GPA greater than or equal to 3.0, an interest in experimental work.
Project Name: Low noise humidity controller for nanoscale imaging
Project ID: R016
Supervisor: Ryan Wagner Number of Positions 1
Project Description: An atomic force microscope (AFM) consists of a cantilever mounted, nanometer scale tip interacting with a surface. In AFM, nanoscale imaging is obtained by scanning the tip over the surface. If an electrical potential is applied to the tip, the electrical properties of the surface can be probed. The presence or absence of water on a surface mediates tip-surface interactions in AFM. For example, a water layer that forms between the surface and tip will affect the contact area, conductivity, capacitance, stiffness, and adhesion of the contact between the tip and sample. In turn, these variations affect AFM measurements of resistance, conductance, piezoelectricity, ferroelectricity, and electrostatic forces. A low noise, fast controller that uses PID control to adjust the humidity of the imaging environment would be a valuable tool for understanding interactions between the surface, water, and tip. The goal of this project is to build such a humidity controller.
Final Deliverables: Prototype humidity controller

Project Name: Interferometric characterization of vibrating structures
Project ID: R017
Supervisor: Ryan Wagner Number of Positions 1
Project Description: Laser doppler vibrometry (LDV) is an interferometric based vibration characterization technique that measures vibrations as small in amplitude as picometers and as high in frequency as gigahertz. A laser is focused on a surface and the velocity as a function of time is recorded. By scanning the laser spot position, the vibrational modes of the sample can be determined. The purpose of this project is to apply LDV to study the vibrational characteristics of numerous systems and structures. You will be trained and educated in the use of a Polytec LDV system and you will support other research groups on campus in carrying out vibrational characterization. Application areas include the characterization of vibrating membranes used for water filtration, studying the vibrational characteristics of natural structures such as insect antennas, and calibration of microcantilevers used in atomic force microscopy.

Project Name: Mechanical loss tangent characterization with atomic force microscopy
Project ID: R018
Supervisor: Ryan Wagner Number of Positions 1
Project Description: An atomic force microscope (AFM) consists of a cantilever mounted, nanometer scale tip interacting with a surface. Because the tip physically interacts with the sample it is possible to use the response of the cantilever to infer the mechanical properties of the surface. The loss tangent is the ratio of energy lost to energy stored in a viscoelastic sample when it is dynamically deformed. This is an important property for understanding the behavior of polymers and biological materials. This project will seek to develop, test, and implement improved methods of loss tangent characterization with AFM. This method will be based on considering how the energy in the sample differs as a function of system operating conditions.
Final Deliverables: Report and/or scientific paper detailing the results.

Project Name: Fabrication of a table-top compression feed screw for particulate materials
Project ID: R028
Supervisor: Prof. M. Gonzalez Prof. C. Wassgren
Number of Positions 2
Project Description: The objectives of this project are to 1. fabricate a table-top compression feed screw for particulate materials
designed by an ME Senior Design (ME 463) team during Summer of 2020, and 2. run the compression feed screw with micro-crystalline cellulose powder and
verify proper operation of all sensors. Compression feed screws are used to convey particulate matter, such as milled or pelleted biomass, into chemical reactor vessels. Compression of the material is needed to densify the material so that when it is fed into the reactor, high pressure reactor gases cannot flow through the material and out through the feed screw. Compression of the material is achieved by tapering the screw barrel so that flow channel area decreases as material moves toward the feed screw exit. The table-top design will be used to gather experimental data for comparison to computational model predictions. The computational models will be used to provide guidance on designing and operating feed screws to feed biomass materials, such as corn stover, into biorefineries.

Project Name: Soft-swelling structures Project ID: R029
Supervisor: Prof. M. Gonzalez Number of Positions 1
Project Description: The objectives of this project are to: 1. Design and build experiments to measure elasto-plastic, absorption and
swelling properties of superabsorbent polymeric or hydrogel spherical particles (Acrylamide/Potassium Acrylate Copolymer Crosslinked) at different water contents, quantified as the percent in weight of water absorbed relative to the dry weight of the sphere;

2. Design and build experiments to measure particle-to-particle transport and bonding formation properties using a packing of hydrogel spheres largely deformed inside a rigid die;
3. Calibrate experimental results with numerical simulations (provided by Prof. Gonzalez) to estimate material properties that cannot be directly measured;
4. Design soft-swelling structures, by tuning the composition of hydrogel mixtures, to achieve targeted structural integrity and morphing capabilities upon water absorption and swelling.
Superabsorbent polymers are highly swelling, chemically cross-linked polymer networks, which are widely used in food, cosmetic, and pharmaceutical applications because of their absorption/release properties. In pharmaceuticals, for example, disintegrant excipients are mainly composed of insoluble polymers that quickly swell upon contact with water. In fact, swelling of individual particles is considered the primary mechanism responsible for tablet disintegration, which, in turn, controls the drug release rate. Therefore, deformation, swelling, and mass transport properties of these polymers are required to model, design, and optimize pharmaceutical solid dosage forms effectively. The goal of this project is to characterize and explore the use soft-swelling structures in structural mechanical applications.

Final Deliverables: The project deliverables and responsibilities are as follows: 1. Measure the swelling equilibrium response, mass absorption kinetics, elasto-
plastic deformation of superabsorbent polymers spherical particles. 2. Design and execute an experimental protocol to measure particle-to-particle
transport and bond strength formation behavior using a packing of hydrogel spheres largely deformed inside a rigid die.
3. Calibrate experimental results obtained in (1) and (2) with numerical simulations provided by Prof. Gonzalez.
4. Design soft-swelling structure with unique structural integrity and morphing capabilities relevant to structural mechanical engineering applications.
5. Report your progress at the end of the semester in a weekly research group meeting. (approx. 15 minutes). The objectives of this meeting are: (i) to give you presentation practice, (ii) keep others in the group up-to-date about the work you are doing, and (iii) get help and advice from the group on your work.
