CuS hollow spheres have been synthesized through a facile microemulsion template route at room temperature using copper naphthenate as metal precursor and thioacetamide as the source of S2−. In our method, the metal precursor and sulfur source dissolved in two different phases; the reaction only...

This study objective was to investigate the biological efficacy of a commercial dispersion of micronized copper azole (MCA) on plantation grown rubberwood. MCA is a formulation containing micronized copper carbonates and azole, an organic co-biocide. The impact of MCA pressure treatments with va...

The potential for migration of pentachlorophenol (PCP) and copper naphthenate (CuNaph) from Douglas-fir was assessed in a bridge over a stream located in Western Oregon in the United States. All rainfall runoff was collected from a portion of the bridge on 15 occasions over a 27 month period and...

For several years, an extensive research program investigating new preservative systems has been ongoing at Mississippi State University. This paper details our continuing experience with field testing of copper naphthenate and other copper carboxylate preservative systems. Results from field st...

The morphology evolution of the mesoporous magnetic composite nanospheres Fe3O4@Poly(4-vinylpyridine) during the formation process and its absorption property of Congo red were studied in this study. A simple solvothermal method was applied for the fabrication of Fe3O4@Poly(4-vinylpyridine) comp...

Magnesium-promoted reductive silylation of 2- and 4-vinylpyridines with chlorotrialkylsilanes in N-methylpyrrolidinone at room temperature led to the selective formation of a variety of the corresponding β-mono-silylated compounds at the terminal carbon atom in good to excellent yields, whereas...

Herein 4-vinylpyridine (4-VP) was employed as the functional monomer to copolymerize with divinylbenzene using 1,2-dichloroethane (DCE) as the porogen, and a series of 4-vinylpyridine-modified post-cross-linked resins was fabricated. The effect of 4-VP and DCE percentage on the porosity, polarit...

The development of facile and environment friendly strategies to metallize the surface of insulating polymeric substrates is of paramount important. An acceptable film adhesion with the polymeric substrate usually requires a chemical pretreatment of the polymer surfaces. Here we report a one-ste...

Cd contamination in agricultural soils threatens the safety of agricultural products and poses human health risk via food chain. However, the remediation of Cd polluted alkaline soils has not drawn the public concern, and the corresponding efficient amendments that can reduce Cd accumulation in ...

A greenhouse experiment was conducted to investigate an enhanced phytoremediation technique for multi-metal contaminated mine tailings by Solanum nigrum L. and using biochar/attapulgite as soil amendments. The 10% attapulgite (MA2) and 10% biochar (MB2) were recommended as the optimum chemical p...

Graphene oxide (GO) based membranes are widely adopted in molecular separation based on size exclusion effect by stacked GO sheets. Both high flux and efficient rejection of GO-based membranes for long-term operation are highly expected for practical applications. Here, an attapulgite (ATP) nano...

The comprehensive sources of particulate matter (PM) require air purification materials to possess both high filtration efficiencies and low air resistances in an effort to provide healthcare. However, the assembly of multiple-layered filters with different functions leads to high pressure drop ...

The salting out potential of potassium-based inorganic salts was assessed in aqueous solutions of two non-ionic surfactants from the Tween family. New solubility data of the systems {surfactant (Tween 20/Tween 80) + inorganic salt (K3PO4/K2CO3/K2HPO4/K2S2O3/K2SO3) + H2O} were experimentally asce...

Sorbitan methacrylate was synthesized from sorbitan dehydrated from d-sorbitol using an immobilized lipase. To optimize the enzymatic synthesis of sorbitan methacrylate, response surface methodology was applied to determine the effects of five-level-four-factors and their reciprocal interactions...

“Biomaterials” is a generic term which refers to a variety of medical material which is designed to be in direct contact with living tissue. Clearly, biomaterials must be carefully and microscopically fabricated for optimal acceptance within the living organism, in both functional and structur...

The interfacial characteristics and antioxidant activities of erythorbyl laurate were investigated to provide information on practical applications as a multi-functional food additive. The critical micelle concentration (CMC) of erythorbyl laurate was 0.101 mM and its foam stability was three ti...

Cocoa butter crystallization in the presence of sorbitan mono- and triesters or canola oil was investigated. Solid-state surfactant esters accelerated early-stage cocoa butter solidification while suppressing later growth. Sorbitan tristearate showed the strongest effect, followed by sorbitan mo...

The reaction of glucose with the borate ion has been studied in an anion exchange membrane. Two complexes, BL− and BL2−, form in the membrane, and their corresponding stability coefficients β1∗ and β2∗ have been determined. The results have revealed that the BL− complex is much more stable in ...

Certain oxoanions form complexes with polyols if the hydroxy groups have a sterically favoured position. Similar properties were found for the chelating resin Wofatit MK 51 which contains methylamino-glucitol groups. The sorption and desorption behaviour of this resin for aluminate, gallate, ger...

HPLC using a borate form of a strongly anion-exchange resin column and an immobilized enzyme reactor for colorimetric detection was used to quantify urinary 1,5-anhydro-d-glucitol. Urine samples were introduced into the system every 7 min without any pretreatment, and after separation of interfe...
