Undergraduate students often find optics and photonics concepts challenging because many phenomena involve wave behavior that is difficult to visualize using equations and static diagrams alone. Topics such as reflection, refraction, Snell's law, total internal reflection, optical ... En savoir plus

Electrochemical CO2 reduction provides a route to convert CO2 into valuable chemicals using renewable electricity, but practical deployment requires stable, scalable, and inexpensive cell components. One major limitation is the anode, as many high-performance CO2 electrolyzers still rely ... En savoir plus

Efficient, stable, and abrupt doping is challenging in semiconductor fabrication, especially in nano-sheet or nano-ribbon transistors. For example, in epitaxial silicon doped above the solubility of phosphorus, most phosphorus dopants are compensated by vacancies. Some of the phosphorus ... En savoir plus

Abstract: Optical systems are a promising platform for quantum computation, but one of the engineering constraints that hinders development in the field is optical loss within linear optical quantum computers (LOQC). LOQC systems use gaussian beams to serve as the qubit source and ... En savoir plus

Industrial CO2 waste streams exhibit significant compositional variability, ranging from pure CO2 to as low as 3%, posing challenges for purification or direct conversion. Electrochemical reduction is a sustainable approach to convert CO2 to valuable products, but faces severe mass ... En savoir plus

This work presents a multiphysics simulation of a Pirani vacuum gauge using COMSOL Multiphysics. Pirani gauges infer pressure from the pressure dependence of gas thermal conductivity by measuring the steady‑state temperature of a resistively heated filament. Accurate modeling is ... En savoir plus

Subcutaneous (SC) and intravitreal (IVT) injections are critical routes of administration for targeted drug therapy, each presenting distinct engineering challenges for combination products such as prefilled syringes and autoinjectors. Successful SC injection requires optimization of ... En savoir plus

Battery packs connect electrochemical cells in series and parallel to meet target energy and power specifications. At the pack level, performance and lifetime are governed by coupled electrical, thermal, and aging heterogeneities that arise from nonuniform current distribution, thermal ... En savoir plus
