Formaldehyde has been regarded as a common indoor pollutant and does great harm to human health, which caused the relevant departments pay attention its accurate detection. At present, spectrophotometry, gas chromatography, liquid other methods have proposed for formaldehyde Among them, sensor is especially suitable gaseous detection with fastest response speed highest sensitivity. Compared sen...

Controlled-release nitrogen fertilizer (CRNF) is expected to meet the nutrient demands for crop growth with single application, so as achieve high-yield, high-efficiency, and labor-saving cultivation. However, under current CRNF practices, a application of in winter wheat (Triticum aestivum L.) usually fails satisfactory effects due insufficient (N) supply later stage, contributing premature le...

Formaldehyde is a volatile organic compound that is widely used in textiles, paper, wood composites, and household materials. Formaldehyde will continuously outgas from manufactured wood products such as furniture, with adverse health effects resulting from prolonged low-level exposure. New, microfabricated sensors for formaldehyde have been developed to meet the need for portable, low-power ga...

Abstract Nitrogen fertilization has been a critical factor for high crop productivity, where urea is currently the most used N source due to its concentration and affordability. Nevertheless, fast solubilization leads frequent losses lower agronomic efficiency. The modification of structure by condensation with formaldehyde proposed improve nutrient uptake plants reduce environmental losses. He...

Polyoxymethylene (POM) is an engineering thermoplastic. Formaldehyde is the monomer unit of this polymer. Depolymeraization of POM occurs at 100 o C and yields formaldehyde whereas thermal degradation occurs at 270 o C. During thermal degradation, POM splits into carbon dioxide, water and formic acid. It has been proved that formaldehyde can be used as hydrogen source, when metallic nanoparticl...

Longstanding mechanistic questions about the role of protecting osmolyte trimethylamine N oxide (TMAO) which favors protein folding and the denaturing osmolyte urea are addressed by studying their effects on the folding of uncharged polymer chains. Using atomistic molecular dynamics simulations, we show that 1-M TMAO and 7-M urea solutions act dramatically differently on these model polymer cha...

Microencapsulated dicyclopentadiene (DCPD) healing agent and Grubbs’ Ru catalyst are incorporated into an epoxy matrix to produce a polymer composite capable of self-healing. The fracture toughness and healing efficiency of this composite are measured using a tapered double-cantilever beam (TDCB) specimen. Both the virgin and healed fracture toughness depend strongly on the size and concentrati...
