Thermogravimetric and differential thermal analysis have been carried out in nitrogen atmosphere for both nanorods, and nanocomposites wit...

Surfactant loaded polymeric hydrogels find applications in several technological areas including drug delivery. Drug transport can be attenuated in surfactant loaded gels through partitioning of the drug in the surfactant aggregates. The drug transport depends on the type of the aggregates and a...

In this work, we report on surface energy and surface reorganization behaviors of a series of fluorinated copolymers poly(perfluorohexylethyl methacrylate)-co-poly[n-alkyl (H or methyl)acrylate], abbreviated as P13FMA-co-P(AnA) or P13FMA-co-P(AnMA), as a function of the lengths of non-fluoroalky...

The direct irradiation of trimethylolpropane propoxylate triacrylate (PPO-TMPTA) – a good chromophore at 193 nm – in thin films of polymethylsilsesquioxanes (PMSSQs), leads to efficient photobleaching at that wavelength with high contrast. The photobleaching is due to loss of the acrylate viny...

1,6-Hexanediol is an emerging building-block chemical, which may be derived from biomass and can produce adipic acid for the synthesis of polymers. A series of supported Pt, Bi-Pt, Au, Pd, Au-Pd, and Au-Pt catalysts were prepared and evaluated in the aerobic oxidation of 1,6-hexanediol to adipic...

H3−2(x+y)MnxCoyPMo12O40 heteropolysalts (x + y ≤ 3/2 and x, y: 0–1.5) were prepared by a cationic exchange method based on barium sulfate precipitation. Structural and textural properties of salts were examined by several physicochemical techniques such as infrared, scanning electron microscop...

As the main toxic component of aristolochic acid, aristolochic acid I (AAI) is primarily found in Aristolochiaceae plants such as Aristolochia, Aristolochia fangchi and Caulis aristolochiae manshuriensis. AAI has been proven to be carcinogenic, mutagenic and nephrotoxic. Although the role of AAI...

Conjugation of DP18L peptide with (R)-3-hydroxydecanoic acid, derived from the biopolymer polyhydroxyalkanoate, enhances its anti-cancer activity (O’Connor et al., 2013. Biomaterials 34, 2710–2718). However, it is unknown if other (R)-3-hydroxyalkanoic acids (R3HAs) can enhance peptide activit...

Gamma-hydroxybutyrate (GHB), a metabolite of GABA, is a drug of abuse and a therapeutic. The illicit use of GHB precursors and analogs reportedly has increased worldwide. Gamma-hydroxyvaleric (GHV) is a 4-methyl-substituted analog of GHB that reportedly is abused and is marketed as a dietary sup...

Engineering enzyme substrate specificity is a promising approach that can expand the applicability of enzymes for the biocatalytic production of industrial chemicals and fuels. In this study, succinic semialdehyde reductase (AKR7A5) was engineered for the conversion of levulinic acid to 4-hydrox...

This study was designed to investigate the metabolism of methanethiol, and the involvement of methanethiol and its metabolites in the transamination pathway of methionine. Gaseous methanethiol, methanethiol-mixed disulfides and dimethylsulfide were formed from 3-methylthiopropionate, a metabolit...

The surface tensions of 2‑diethylaminoethanol (DEAE)‑N‑(2‑aminoethyl)ethanolamine (AEEA), DEAE‑N‑methyl‑1,3‑propane‑diamine (MAPA) and DEAE‑1,4‑butanediamine (BDA) aqueous solutions have been measured by using the BZY-1 surface tension meter. The mass fractions of DEAE and AEEA/MAPA/BDA respecti...

A new set of values for the molar heat capacities of N-(2-aminoethyl)piperazine (AEP) and N,N,N′-trimethylethylenediamine (tMEDA) and their aqueous mixtures over the whole range of compositions are reported in the present work. Molar heat capacities of ternary mixtures of each polyamine with pi...

To study the applicability and mechanism of the visible-light-driven photo-reduction of Cr(VI) is important since it will elucidate the chromium cycle in natural circumstances, and since this reduction reaction is important in treating wastewater contaminated by Cr(VI). Herein, we conducted an i...

Electronic absorption spectra have been obtained for chromate, dichromate, chlorochromate, manganate and permanganate ions in argon and dinitrogen gas matrices, poly(vinyl alcohol) films and Nujol mulls at c. 12 and 77 K. All the ions showed well resolved vibrational progressions. There was a go...

Growth and cesium uptake responses of plants to elevated CO2 and microbial inoculation, alone or in combination, can be explored for clean-up of contaminated soils, and this induced phytoextraction may be better than the natural process. The present study used open-top chambers to investigate co...

The preparation and characterization of a novel material, multilayers of nickel hexacyanoferrate immobilized on mesoporous propyl-ethylenediamine triacetate functionalized silica supports, and its uses as a cesium sorbent and a cesium sensing material is reported. The preparation of nickel hexac...

The heat capacity of a sample of Cs2Cr2O7 was determined in the temperature range 5 to 350 K by aneroid adiabatic calorimetry. The heat capacity at constant pressure Cpo(298.15 K), the entropy So(298.15 K), the enthalpy increment {Ho(298.15 K) − Ho(0)}, and the function −{Go(298.15 K) − Ho(0)}29...
