Microfluidic Concentrator for Label-Free, Continuous Nanoparticle Processing

SUMMARY Microfluidic sample concentration devices enable a departure from expensive centrifugation devices and immobile processes that are used presently to concentrate and capture targeted nanoparticles. Because of their ability to significantly reduce sample size and enable sensitive and rapid detection systems, microfluidic sample concentration...

A Solid State Process for Fabricating Single Crystals from Glass

Technology Glass can be directly converted into a single crystal, avoiding the gaseous or liquid phase. Sb2S3 single crystals were grown in 16SbI3–84Sb2S3 glass as an example of this approach. As confirmed in this first unambiguous demonstration of an all-solid-state glass to crystal transformation, extraneous nucleation can be avoided during...

A New Antenna-feedback Scheme to Achieve Emission in a Narrow Beam from Metal-cavity Semiconductor Lasers

SUMMARY The invention is based on a distributed antenna-coupling (feedback) scheme and specially designed distributed feedback (DFB) metallic cavity grating. By ensuring the predesigned phase condition, the mode traveling inside the waveguide is coupled/phase-locked to the mode traveling outside on the top metal, hence establishing a standing-wave...

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...

Fabrication of Nano-Macro Porous Glass with a Water Soluble Pore Former

SUMMARYLehigh University has developed a superior method for creating interconnected nano-macro porous glass. Most often glass is used as one monolithic solid. However, it becomes the material of choice for many other applications in tissue engineering, catalysis, virus separation, etc., if it is made with controlled porosity. For example in regenerative...
