HMF is an important chemical product since it has the potential to be used as a feedstock to replace petroleum-derived aromatics for production of a range of specialty chemicals and plastics.In this work, we will demonstrate an economically-viable, ionic liquid catalytic process for conversion of...

Traditional vapor compression air conditioners have very high power consumption for cooling of hot and humid air due to condensation of a large amount of water inside the cooler. We have developed a novel zeolite membrane supported on a thin (~50 micrometer thick) porous metal sheet to remove water...

Ionic liquids (ILs) are a new class of substances exclusively composed of cations and anions, and they have shown unique physico-chemical properties differing from aqueous ionic solutions and high temperature molten salts. Although many attentions have been paid on ILs, the knowledge of ILs is...

Progress in the transesterification of vegetable oils has been achieved using ionic liquids. Ionic liquids have been found to provide an ideal medium for increasing the biodiesel yield, stabilizing the inorganic acid and removing the glycerol by-product. In this present study, transesterification...

Thin film composite and dense membranes were produced by casting a blend of BPS-20 (20% disulfonated poly(arylene ether sulfone)) or BPS-32 (32% disulfonated poly(arylene ether sulfone)) and varying molecular weights of poly(ethylene glycol) oligomer onto porous Udel polysulfone foam. An additional...

The use of corn as an expression host is an attractive system for the production of plant-made proteins. The use of plants lowers upstream costs making downstream the significant production cost. For some proteins, crossflow ultrafiltration could be a lower cost alternative. The potential for doing...

The pharmacokinetic profiles of monoclonal antibody charge variants are poorly understood because they differ only slightly from the “main” antibody species, are low in abundance, and extremely difficult to isolate in pure pools for intensive in vitro and in vivo studies. Because of this, the...

Carbon capture and sequestration (CCS) can be an important component of reducing worldwide CO2 emissions from stationary point sources, such as coal-fired power plants. Aqueous amines and ammonia are being demonstrated for CO2 capture in a temperature swing cyclic process. Solid sorbents can also...
