Buffering to achieve pH control is crucial for successful trichloroethene (TCE) anaerobic bioremediation. Bicarbonate (HCO3-) is the natural buffer in groundwater and the buffer of choice in the laboratory and at contaminated sites undergoing biological treatment with organohalide respiring microorganisms.

When lysozyme is dissolved in a neutral HEPES buffer solution (pH = 7.4) with 0.001-0.050 M TCEP added, a fast phase transition process occurs and the resulting novel fiber-like hierarchical supramolecular assemblies made by primary spherical-particle aggregation can function as a "superglue"

A highly fluorescent Zn(2+) complex of the triazole linked salicyl-imino-thiophenyl conjugate of calix[4]arene, [ZnL] has been demonstrated to be a chemo-sensing ensemble for the recognition of His and Cys among the naturally occurring amino acids in HEPES buffer milieu. The

The crystal structure of the NTF2-like domain of the Drosophila homolog of Ras GTPase SH3 Binding Protein (G3BP), Rasputin, was determined at 2.7Å resolution. The overall structure is highly similar to nuclear transport factor 2: It is a homodimer comprised

We have developed a quickly responsive, and specific fluorescent assay for the detection of Au(III) on the basis of the formation of gold nanoparticles in the presence of HEPES, which cleave the C-I bond of I-BODIPY 1 to yield the
