Hydrophobic and Hydrophilic Surface Design in NASA Spacecraft Engineering: The Effect of Geometry and Microgravity on Landing Dynamics and Crew Safety

Engineering Technology: Statics & Dynamics

Hydrophobic surfaces repel water (are water-fearing) while hydrophilic surfaces attract water (water-loving). From this knowledge, we can discover and make observations on how different mate…

Hydrotectives 2.0: Testing Sodium Alginate and Carboxymethyl Cellulose Hydrogel Beads for Targeted Delivery of Acetaminophen

Chemistry

Objective: Acetaminophen (APAP) should ideally be absorbed in the small intestine, but up to 15% of the drug is released in the stomach, resulting in suboptimal delivery. This study evaluate…

Hyperactive (Autoimmunity) vs. Dysfunctional (Cancer) T Cells: Two Sides of the Same Coin

Cellular and Molecular Biology Second Award

Cancer and autoimmune diseases present an immunological paradox: T cells adopt opposing functional states. In cancer, T cells become dysfunctional and lose effector function, failing to elim…
