A molecular sieve is a material with pores (voids or holes), having uniform size comparable to that of individual molecules, linking the interior of the solid to its exterior. These materials embody …

Jul 8, 2024 · In this study, we developed a hydrophilic dual-enzyme microreactor characterized by rapid mass transfer and superior enzymatic activity. Initially, we selected KIT-6 molecular …

Jan 1, 2017 · The carbon membrane derived from glucose (CM-Glu-0.133) shows a decreasing permeability trend with increasing kinetic diameter of the gases (i.e. gas permeability in the …

Nov 22, 2000 · Valyl-tRNA synthetase (ValRS) strictly discriminates the cognate L-valine from the larger L-isoleucine and the isosteric L-threonine by the tRNA-dependent “double sieve” …

Nov 20, 2019 · In this work, mesoporous molecular sieves, i.e., SBA-15, KIT-6 and MCM-41, chemically modified with a chiral selector, N-acyl-protected d -glutamic acid, were used to …

Confocal laser-scanning microscopy localized the Fd-GOGAT protein to the phloem companion cells-sieve element complex in the leaf veins. The results are consistent with a role of Fd …

Jan 29, 2024 · In the sieving process, when pouring the mixture onto the mesh, unwanted particles are trapped, allowing only the purified liquid glue to flow to the next stage. This …

E11 Acrylic Frame Test Sieves are designed to reduce sample loss, while the ASTM E11 Precision Electroformed Mesh Sieves offer precise particle sizing of fine powders. Air Jet …

Gly and Ala, Val and Leu, Ser and Thr, Asn and Gln, and Asp and Glu are the amino acid pairs with single carbon differences that can be used in the double-sieve proofreading mechanism. …
