Use of Soy Proteins or Soy Derivatives and Zero-Valent Iron for Environmental Remediation
SUMMARY Lehigh has developed a novel material for the treatment of contaminated water and soil. The method for the preparation of such materials involves the dispersion of zero-valance nanoscale iron particles and use of either soy protein, soy milk, or other soy derivatives. These particles have large surface areas, giving them increased reactivity...

Periodic Mesoporous Phosphorous (V)-oxyimide
SUMMARY Stishovite is the hardest oxide material known and because it is an oxide, it is resistant to corrosion. It can be incorporated into machine tools for processes such as cutting and grinding, and can be used for polishing applications. However, the cost of making Stishovite has inhibiting greater adoption. Lehigh University has addressed this...
