The structural Basis of NMN synthesis catalyzed by NadV from Haemophilus ducreyi.

NMN is a precursor in the biosynthesis of NAD, a molecule that plays a crucial role within cells. Supplementation with NMN can elevate NAD levels in the blood, improving symptoms of diabetes, neurodegenerative diseases, and cancer, as well as providing anti-aging benefits. Escherichia coli was engineered to heterologously express nicotinamide phosphoribosyltransferase (Nampt), enabling the recombinant E.

Fabrication and Luminescence Properties of Highly Transparent Green-Emitting Ho:YO Ceramics for Laser Diode Lighting.

Highly transparent Ho:YO ceramics for laser diode lighting were prepared using the vacuum sintering method with 0.3 at.% NbO as a sintering additive.

Fabrication and Luminescent Properties of Highly Transparent Er:YO Ceramics by Hot Pressing Sintering.

Highly transparent Er:YO ceramics (1-9 at.% Er) were fabricated by hot pressing sintering with ZrO as the sintering additive. The microstructures, transmittance, luminescent properties, thermal conductivity, and mechanical properties of the Er:YO ceramic samples were investigated in detail.

Synthesis of Multiwall Boron Nitride (BN) Nanotubes by a PVD Method Based on Vapor-Liquid-Solid Growth.

Multiwall boron nitride (BN) nanotubes were synthesized by a novel physical vapor deposition (PVD) method, in which the BN nanotubes grow on a compact substrate composed of AlN, γ-AlO, YO, and carbon powders. The obtained BN nanotubes assemble in an orderly manner with a typical length of over one millimeter and a diameter of one-hundred nanometers. The hollow multiwall tubes have a spherical tip, which is presumed to be a liquid drop at the synthesis temperature, indicating the vapor-liquid-solid (VLS) growth mechanism.

Immobilized Cerrena sp. laccase: preparation, thermal inactivation, and operational stability in malachite green decolorization.

Laccases are polyphenol oxidases with widespread applications in various industries. In the present study, the laccase from Cerrena sp. HYB07 was immobilized with four methods, namely entrapment in alginate, covalently binding to chitosan as well as formation of cross-linked enzyme aggregates (CLEAs) and magnetic CLEAs (M-CLEAs).
