1.A hydrometallurgical process for recovering total metal values from waste monolithic ceramic capacitors.
Prabaharan G1, Barik SP2, Kumar B1. Waste Manag. 2016 Apr 12. pii: S0956-053X(16)30173-8. doi: 10.1016/j.wasman.2016.04.010. [Epub ahead of print]
A hydrometallurgical process for recovering the total metal values from waste monolithic ceramic capacitors was investigated. The process parameters such as time, temperature, acid concentration, hydrogen peroxide concentration and other reagents (amount of zinc dust and sodium formate) were optimized. Base metals such as Ba, Ti, Sn, Cu and Ni are leached out in two stages using HCl in stage 1 and HCl with H2O2 in stage 2. More than 99% of leaching efficiency for base metals (Cu, Ni, Ba, Ti and Sn) was achieved. Precious metals such as Au and Pd are leached out using aquaregia and nitric acid was used for the leaching of Ag. Base metals (Ba, Ti, Sn, Cu and Ni) are recovered by selective precipitation using H2SO4 and NaOH solution. In case of precious metals, Au and Pd from the leach solution were precipitated out using sodium metabisulphite and sodium formate, respectively. Sodium chloride was used for the precipitation of Ag from leach solution.
2.Forsythia suspensa fruit extracts and the constituent matairesinol confer anti-allergic effects in an allergic dermatitis mouse model.
Sung YY1, Lee AY2, Kim HK3. J Ethnopharmacol. 2016 Apr 13. pii: S0378-8741(16)30207-0. doi: 10.1016/j.jep.2016.04.015. [Epub ahead of print]
ETHNOPHARMACOLOGICAL RELEVANCE: Forsythia suspensa is used in traditional medicine to treat inflammation. To clarify the anti-inflammatory and anti-allergic effects of F. suspensa fruits, we determined the therapeutic effects of crude extract, fractions, and a constituent from F. suspensa fruits on a murine atopic dermatitis (AD) model.
3.Combined morphine and limb remote ischemic perconditioning provides an enhanced protection against myocardial ischemia/reperfusion injury by antiapoptosis.
Wang SY1, Cui XL1, Xue FS2, Duan R3, Li RP1, Liu GP1, Yang GZ1, Sun C1. J Surg Res. 2016 May 1;202(1):13-25. doi: 10.1016/j.jss.2015.12.007. Epub 2015 Dec 15.
BACKGROUND: Both morphine and limb remote ischemic perconditioning (RIPer) can protect against myocardial ischemia/reperfusion injury (IRI). This experiment was designed to assess whether combined morphine and limb RIPer could provide and enhanced protection against myocardial IRI in an in vivo rat model.
4.Synthesis and evaluation of a novel cationic konjac glucomannan-based flocculant.
Ren WJ1, Zhang AQ2, Qin SY1, Li ZK1. Carbohydr Polym. 2016 Jun 25;144:238-44. doi: 10.1016/j.carbpol.2016.02.061. Epub 2016 Feb 24.
A novel cationic flocculant of konjac glucomannan-graft-poly-(2-methacryloyloxyethyl)trimethyl ammonium chloride (KGM-g-PDMC), was successfully synthesized by using acidic ammonium cerium (IV) nitrate (CAN) as initiator in homogeneous aqueous solution. The graft copolymer was characterized using Fourier-transform infrared (FT-IR) spectroscopy, (1)H nuclear magnetic resonance ((1)H NMR), thermogravimetric analysis (TGA) and elemental analysis. The influences of degree of substitution (DS) of KGM, concentration of NaCl and pH value on turbidity removal rate of the cationic flocculant were investigated. The results demonstrated that the flocculant exhibited excellent flocculating ability in the presence of salt and a wide range of pH (1<pH<9). With DS of 0.2, the turbidity removal rate of flocculant to 0.1% kaolin suspension could reach more than 90% at pH 7.0. The flocculation mechanisms were investigated by screening effect and means of zeta potential.
