Preparation of radiation-resistant high-performance polyphenylene sulfide fibers with improved processing

Tribological studies of polyphenylene sulfide composites filled with micro/nano particles and reinforced with short fibers or carbon nano-tubes/carbon nano-fibers

Monolysocardiolipin: improved preparation with high yield.

A simple, high-yielding preparation of monolysocardiolipin (MLCL) by phospholipase A2 hydrolysis of cardiolipin (CL) in methanol on a semi-preparative scale is described. In methanol, phospholipase A2 preferentially hydrolyzes CL to MLCL. This selectivity results in ∼80% yield of MLCL. The synthesized MLCL and dilysocardiolipin were characterized by NMR and ESI-MS/MS. Only the sn-2 position of ...

Transverse compression of high-performance ballistic fibers

Guo, Zherui M.S.A.A., Purdue University, August 2014. Transverse Compression of High Performance Ballistic Fibers. Major Professor: Weinong Chen. High performance ballistic fibers have been in use for decades, specifically in protective applications against ballistic impact such as bulletproof vest layers and aircraft turbine engine fragmentation barriers. These high performance fibers have ext...

Improved High Performance Trays

From a design and hydraulic standpoint, trays are relatively complex distillation internals. In the ongoing search for higher performance trays, one first must understand the hydraulic and mass transfer aspects of the tray operation such as entrainment, downcomer flooding, and vapor liquid contact. When this is well understood, then various aspects of the deck and/or downcomer designs can more ...

Preparation of polymer/POSS nanocomposites by radiation processing

Multifunctional polyhedral oligomeric silsesquioxane (POSS)-reinforced polypropylene (PP) nanocomposites were prepared by a simple and economical radiation processing, which has a great potential for the preparation of high performance materials. The tensile strength of PP/POSS nanocomposites increased with an increasing POSS content up to 5 wt% and with an increasing absorption dose up to 50 k...
