Synthesis of a Large Pore Periodic Mesoporous Slicas with Crystalline Channel Walls at Pressures <5 GPa

SUMMARYPeriodic mesoporous silica materials were first discovered by Mobil Oil in 1992 for use in petroleum cracking applications. It was envisaged that these larger pore materials would allow for a more effective processing of the heavier hydrocarbon molecules than microporous zeolite catalysts. However, this did not happen because the mesoporous silicas...

Facile, High Yield Synthesis and Purification of CdS Quantum Dots from Optimized Strains of S. maltophilia

SUMMARY A major barrier to the utilization of quantum dots (QDs) in commercial applications is the high cost associated with conventional chemical synthesis as well as the use of high temperatures and toxic solvents, thereby requiring specialized, expensive waste disposal procedures. Lehigh University has developed an optimized, bacterial-based synthesis...

Carbon Dioxide Capture

SUMMARY Lehigh University has developed a new class of porous organonitridic materials (PECONFs) with an attractive combination of characteristics for gas separation, including removing carbon dioxide from flue gas. The materials adsorb high amounts of CO2 (up to 3.5 mmol.g-1 at 1 atm and 273 K) and exhibit high selectivities (CO2 : N2 = 109) and heats...

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...

Dispersed Zero-Valent Iron Colloids

SUMMARY Stable dispersions of zero-valent iron particles are produced by milling of micro- and nano-scale iron particles (colloids) in the presence of a dispersant or dispersants. The present invention is a process for preparing zero-valent iron suspensions which can be used directly at the source of the pollution, applied to deep aquifers, and spread...
