A series of gamma-[Glu]((n= 2,3,4))-Val or gamma-[Glu]((n= 2,3,4))-Met were synthesized in the presence of donor (Gln) and corresponding acceptor (Val or Met) through transpeptidation catalyzed by the glutaminase from Bacillus amyloliquefaciens. Gln in excess significantly (p <.05 improved the yield of gamma-> 1))-Val/Met except for gamma-Glu-Val/Met. The Km values for transpeptida...

Due to antitumor and antioxidant activities, there has been increasing interest in fucoidans, sulfated polysaccharides, from brown algae. Currently, the classic hot water extraction and acid extraction are time-consuming, and can cause the partial cleavage of sulfate esters, leading to bioactivity loss. The present study developed a novel process f...

Hexagonal boron nitride (h-BN) nanosheets were synthesized through a facile two-step roasting process by using boric acid and melamine as raw materials under ammonia atmosphere. The average thickness of the nanosheets was 16 nm. The porous h-BN nanosheets displayed enhanced performance for the removal of copper ion (Cu2+) with adsorption capacity u...

Nanomaterials constructed by self-assembly of biomolecules are of particular interest as drug delivery carriers in biomedicine. However, supramolecular construction of nanoparticles by self-assembly of highly hydrophilic biomolecules such as hyaluronic acid still remains a formidable challenge due to their water solubility. Herein, we propose a str...

A numerical model has been developed for struvite-crystallization in a fluidized bed reactor (FBR). For the first time, the flow field and crystal size distribution (CSD) are simultaneously obtained via solving the model that couples computational fluid dynamics (CFD) and population balance equation (PBE). The model was first verified based on the ...

A swelling-dependent two-fluid model (STFM) is developed for the liquid-solid flows of swelling particles in polyethylene reactors. The model integrates the two-fluid model (TFM) with a species transport equation (STE) to account for the diffusion of alkane molecules from the liquid bulk to the amorphous region of particles, and a population balanc...

Four kinds of CuO catalysts with well-controlled leaf-like (L-CuO), flower-like (F-CuO), sea-urchin-like (U-CuO), and oatmeal-like (O-CuO) morphologies were synthesized by a facile precipitation method assisted by various chelating ligands. High-resolution transmission electron microscopy and fast Fourier transform infrared spectroscopy indicated t...

The energy-minimization multiscale (EMMS) principle of compromise in competition is believed to be generally applicable for all mesoscale problems at different levels in the real world, spanning from elementary particles to the universe. This stimulated a fundamental proposition of the concept of mesoscience. This article discusses a potential univ...

Microalgal biodiesel has emerged as an environment friendly alternative to the existing fossil fuels. The commercial production of this biodiesel is still challenging due to several technical and economic issues, which span from mass cultivation of microalgae to the biodiesel production. Mass cultivation is the most critical step in terms of water ...
