Abstract Synthesis of water‐soluble‐substituted pyridinium cation which is attached with base sensitive fluorophore peripheral units different inorganic counter anions under conventional/silica‐supported Muffle furnace methods. Solvent‐free synthetic approach has more merits than the conventional method, such as non‐toxic, shorter reaction time, easy workup procedure without purification proces...

1. Liver and bone alkaline phosphatase isoenzymes were solubilized with the zwitterionic detergent sulphobetaine 14, and purified to homogeneity by using a monoclonal antibody previously raised against a partially-purified preparation of the liver isoenzyme. Both purified isoenzymes had a specific activity in the range 1100-1400 mumol/min per mg of protein with a subunit Mr of 80,000 determined...

We present a theoretical analysis of the dynamics one-dimensional spin-1/2 fermionic gas subject to weak two-body losses. Our approach highlights crucial role played by spin conservation in determination full time evolution. focus particular on that is initially prepared Dicke state with fully-symmetric wavefunction, band insulator, or Mott insulator. In latter case, we investigate emergence st...

Seaweed residues from Alaria esculenta , Saccharina latissima and Ascophyllum nodosum after alginate extraction have been valorized to produce cellulose-based fractions with different purification degrees. The were mainly composed of carbohydrates (35–57%) proteins (12–37%), being richer in cellulose fucoidan. lower content the latter made it unsuitable for cellulosic fractions. Self-supporting...

Background: Alkaline pectate lyase plays an important role in papermaking, biological refining and wastewater treatment, but its industrial applications are largely limited owing to low activity poor alkali resistance. Methods: The alkaline BspPel from Bacillus RN.1 was heterologously expressed Escherichia coli BL21 (DE3) resistance were improved by loop replacement. Simultaneously, the effect ...
