Wearable Devices For Single Cell Sensing And Transfection, Lingqian Chang, Yu-Chieh Wang, Faheem Ershad, Ruiguo Yang, Cunjiang Yu, Yubo Fan

Department of Mechanical and Materials Engineering: Faculty Publications

Transdermal drug delivery systems have been successful for decades. Now these devices can be further scaled down, and their applications have been extended to wide selections of cargo, ranging from natural molecules (e.g., insulin and glucose) to bioengineered molecules (e.g., nanoparticles and vaccines). Some emerging nanopatches show promise for precise single-cell gene transfection in vivo and have advantages over conventional tools in terms of delivery efficiency, safety, and controllability of delivered dose. In this review, we discuss recent technical advances in wearable micro/nano devices with unique capabilities or potential for single-cell biosensing and transfection in the skin or other organs, …

Segregation Of Mo Atoms Into Stacking Faults In Crfeconimo Alloy, Kaisheng Ming, Xiaofang Bi, Jian Wang

Department of Mechanical and Materials Engineering: Faculty Publications

Solute segregation at dislocations can impede the motion of dislocations, strengthening materials. Here, we study the formation and role of solute segregation at dislocations in CrFeCoNiMo high-entropy alloys (HEAs) by high-angle annular dark-field scanning transmission electron microscopy imaging and mechanical testing both deformed and annealed samples. Mo atoms exhibit pronounced segregation into the planar-extended core of dislocations, i.e. stacking faults, causing the increase in the yield strength while the loss of the ductility. This work suggests that mechanical properties of HEAs can be tailored by alloying additional elements that are in favor of segregation into dislocations.

Department of Mechanical and Materials Engineering: Faculty Publications

Increasingly targeted in drug discovery, protein-protein interactions challenge current high throughput screening technologies in the pharmaceutical industry. Developing an effective and efficient method for screening small molecules or compounds is critical to accelerate the discovery of ligands for enzymes, receptors and other pharmaceutical targets. Here, we report developments of methods to increase the signal-to-noise ratio (SNR) for screening protein-protein interactions using atomic force microscopy (AFM) force spectroscopy. We have demonstrated the effectiveness of these developments on detecting the binding process between focal adhesion kinases (FAK) with protein kinase B (Akt1), which is a target for potential cancer drugs. These developments …

Design And Manufacturing Of A 3d Printer For Teaching And Research, Rafiqul Noorani, Michael Lynch, Patrick Hodgkiss, Matt Fumo, Christopher Burke

Mechanical Engineering Faculty Works

The goal of this paper is to design and fabricate a 3D printer that will be the most accurate and cost-effective printer possible, while still being faster than the Rapid Prototyping (RP) Lab's Stratasys FDM-1650 at Loyola Marymount University. This project is done to greatly increase the capability of the RP lab in addition to exposing students to the design and fabrication of a 3D printer. To complete the construction of the printer, the design is originally generated in Solidworks to ensure the components would work together effectively and to aid with design selection. The frame is then constructed using …

Hydro-Aeroponic Design, Megan J. Doll, Nathan J. Boring, Meredith B. Taylor, Chancelor L. Sunkle

Williams Honors College, Honors Research Projects

“Aeroponics” is a plant cultivation technique where roots hang suspended in the air while the nutrient solution is delivered in the form of a fine mist. NASA has done experiments in space and found out that plants grow very well with aeroponic technology. However, “Hydroponics” is the most preferred method, where plants are grown in a non-soil medium, and mostly in nutrient liquid that flows through rectangular channels. There are advantages and disadvantages to each system. With the intention of combining the efficiency of aeroponics and the compactness of hydroponics, a hydro-aeroponic system was created to grow spinach and lettuce. …

Metric Coil Car, Abigail Eberly

Williams Honors College, Honors Research Projects

Coil cars are a vital part of many steel mills. They allow mills to easily transfer a coil from one location to another without the use of a crane, manual labor, or other extraneous forces. Steel Equipment Specialists, or SES, gets multiple orders every year for coil cars. While the general functions and goals of the cars remains consistent, the details, such as the size of the car, the distance between rails, and the weight/ size of the coils differs between each place. Due to this variety, SES has requested a coil car that can easily be manipulated and produced …

Theoretical Study Of Fano Resonance In A Mechanical System, Alex Alberts

Williams Honors College, Honors Research Projects

Resonance conditions are a major area of study in theoretical and experimental investigation. Normally, a resonance condition is characterized by a symmetric shape on either side of the resonance. In some cases, we can observe an asymmetric resonance shape, which is called a Fano resonance. We will study the appearance of Fano resonance in a purely mechanical system. The frequency response of the primary system is approximated using the method of multiple scales focusing on the location of the resonance condition. Then, curve fitting is used to approximate the Fano parameter associated with the system, which provides a measurement of …

Generator Design: A Study Of Optimized Airflow, Rachel Wattleworth

Williams Honors College, Honors Research Projects

The core goal of this project was to prototype, test, and evaluate a new type of fan for the Safran Electrical & Power air-cooled generators. The idea of a new fan being made for these two generators arose when they were not adhering to design requirements. A base mixed-flow fan was created to test on multiple generators. Upon creating a prototype, it will be tested to prove if it can increase the air flow, decrease temperatures, and increase power and life of the machines. They all proved to be successful and achieve the main objectives for this project. Data such …

Power Wheelchair Canopy, Mohamed F. Battah, Joshua D. Brown, Dujuan J. Mcclendon, Gavin M. Francisco

Williams Honors College, Honors Research Projects

Some power wheelchair users can not drive and independently hold an umbrella at the time because they do not have much upper body strength. Therefore, users are unprotected from the rain and are getting soaking wet. One of the members of this group is in a wheelchair and faces this problem. He has previously searched for something to protect him from rain, but could not found something he could independently use. What users need is a powered umbrella that attaches to their power wheelchair. There is no such umbrella available in the market. In this project, the solution to this …
