Lignocellulosic biomass is a new source of renewable and carbon neutral materials for biofuel and bioenergy production. However, we note the recalcitrance of lignocellulosic for bioconversion. The presence of lignin is a barrier to enzymatic hydrolysis of cellulose by cellulases, as well as...

Li-air batteries have much higher gravimetric energy storage density compared to all other battery chemistries, and this has led to a strong interest in seeing if such batteries could be developed for powering EVs, enabling driving ranges comparable to gasoline powered automobiles. However, many...

During mesophilic or thermophilic anaerobic digestion, a considerable fraction of organic nitrogen is mineralized to ionic ammonia, producing an effluent with higher concentrations of ammonia nitrogen as well as elevated temperatures, both of which can be useful in dowstream processing of ammonia...

Design of Experiments (DOE) is the most effective method to achieve product and pro­cess efficiency and optimization. Design of Experiment (DOE) studies can help develop process development knowledge by revealing relationships, including multifactorial interactions, between the variable inputs (e.g...

Writing and printing papers are usually loaded with white pigment particles to improve many paper properties such as light scattering, smoothness, pore-size distribution, and ink-paper interactions. In the conventional method of loading, the filler particles are added directly into the papermaking...

Chemical looping combustion (CLC) for power generation has the inherent potential of enriching CO 2 from flue gases in-situ with low energy penalty compared to other commercial available options. However, the feasibility of applying CLC to burning coal is heavily depended on the suitability of...

The motivation to switch the fossil fuels to an alternative fuel is an emerging area of research and development during the past decade. Hydrogen is a clean energy carrier for sustainable consumption that can be used in various goals such as raw materials in ammonia and methanol manufactures as...

5-Hydroxylmethylfurfural has garnered wide interest as a potential bio-based commodity chemical due to its multiple reactive groups and relatively easy formation from fructose and other sugars. For example HMF can be produced from fructose in DMSO in high yields; however the separation is difficult...
