Poly(dimethylsiloxane) (PDMS) has been widely employed in biomedical disciplines due to its several advantages, including biocompatibility, nontoxicity, and low-cost preparation. However, the intrinsic hydrophobicity of this material encourages biofouling reduces cell regulation capacity, thereby limiting applicability. The purpose study is explore surface modification functionalization PDMS PD...

Sodium-ion batteries can be the best alternative to lithium-ion batteries, because of their similar electrochemistry, nontoxicity, and elemental abundance and the low cost of sodium. They still stand in need of better cathodes in terms of their structural and electrochemical aspects. Accordingly, the present study reports the first example of the preparation of Na2/3(Fe1/2Mn1/2)O2 hierarchical ...

A new controlled release fertilizer was developed by coating urea particles with bio-based polyurethane. Coating materials were synthesized from liquefied wheat straw, isocyanate, and castor oil. The effects of liquefied solvents, mass ratio of liquid to solid, size of wheat straw, and reaction time during liquefaction process on the nitrogen release rate of polyurethane-coated urea (PCU) were ...

Curcumin, the active component of turmeric, is a polyphenolic phytochemical with anti-tumor, antiinflammatory, anti-oxidative and anti-allergic properties. Mast cells participate in allergic inflammation by virtue of their ability of being activated to allergens and lead to the release of number of biologically active mediators including histamine, prostaglandins, leukotrienes, various cytokine...

The nontoxic protein component in supernatant fluids of young cultures of the cholera vibrio in peptone dialysate broth contains an antigen identical in specificity to vibrio lipopolysaccharide. This material was heterogeneous after elution from diethylaminoethyl A50 Sephadex, and it contained at least five additional minor antigens. Identity was demonstrated by immunodiffusion methods, by the ...

A novel method is proposed using nanometer-sized diamond particles as detection probes for biolabeling. The advantages of nanodiamond's unique properties were demonstrated in its biocompatibility, nontoxicity, easily detected Raman signal, and intrinsic fluorescence from its natural defects without complicated pretreatments. Carboxylated nanodiamond's (cND's) penetration ability, noncytotoxicit...

Background Tissue engineering is an interdisciplinary field that attempts to restore or regenerate tissues and organs through biomimetic fabrication of scaffolds with specific functionality. In recent years, graphene oxide (GO) is considered as promising biomaterial due to its nontoxicity, high dispersity, and hydrophilic interaction, and these characteristics are key to stimulating the interac...

the effect of vanillin on the corrosion behavior of aa6061 al alloy in 3.5% nacl solution wasinvestigated using potentiodynamic polarization and electrochemical noise (en) techniques. vanillinoffers interesting possibilities for corrosion inhibition due to its nontoxicity and high solubility inaqueous media. the best inhibition effect at 200 ppm vanillin was a marked characteristic of theinhibi...

Zinc oxide (ZnO) is used for various purposes because of its special physico-chemical properties, including large band gap, high binding energy exciton, nontoxicity, chemical and thermal stability, piezoelectric constants, wurtzite crystal structure with widespread applications in electronics, optoelectronics, biochemical sensing, biomedical, energy-saving systems. This review mainly aimed to p...

Bismuth subnitrate is reported herein as a simple and efficient catalyst for the atom-economical synthesis of methyl ketones via Markovnikov-type alkyne hydration. Besides an effective batch process under reasonably mild conditions, chemically intensified continuous flow protocol was also developed in packed-bed system. The applicability methodologies demonstrated through hydration diverse set ...
