Desktop Slide Impactor

BACKGROUND Although impact testing is extensively used in the research, development, and quality control of mechanical structures, slide impactors delivering shear impact on an external surface (i.e., “slide impact”) has not yet been developed. The lack of a commercially available device to evaluate realistic slide impacts means a narrow...

Mie-resonator Solar Thermal Absorbers

BACKGROUND Harnessing solar energy as a replacement for fossil fuels is an important avenue in addressing climate change. An exemplar issue facing the utility and scalability of this energy source is solar-to-heat conversion efficiency in photothermal layers. More specifically, both reflectance/transmission heat loss and convection/radiation heat transfer...

Photobiodegradable Plastics via PPDvSOP improvement

BACKGROUND At first plastics were welcome as blessings. Specifically, their durability, high strength per weight and low cost have made them the ideal packaging materials. However, the last seven decades have proved, those same attributes combined with improper waste management, led to a plastic pollution problem. An estimated 6300 million metric tons...

Nanowire-Nanoparticle Conjugate Photolytic Fuel Generators

Background Conversion of sunlight to chemical fuels by artificial photosynthesis has been a long-sought goal. In particular, significant research activity was stimulated towards photolytic cells producing hydrogen in 1972, when Fujishima and Honda demonstrated water could split to hydrogen and oxygen under sunlight (photolysis) using an n-type TiO2...

Method for fabrication of high dispersion polymer nanocomposites

BACKGROUND Polymers, molecules composed of repeated subunits, are the building blocks for many materials including synthetic plastics, rubber, and nylon. Polymer nanocomposites (PNCs) are polymers with nanofillers (nanoparticles) dispersed throughout the polymer's matrix. Addition of the nanofillers greatly improves the physical properties of the...
