cis-Diamminediiodoplatinum (cis-DIDP) is a cisplatin-like anticancer drug with higher anticancer activity, but lower stability and price than cisplatin. In this study, a cis-DIDP carrier system based on micro-sized stearic acid was prepared by an emulsion solvent evaporation method. The maximum drug loading capacity of cis-DIDP-loaded solid lipid nanoparticles was 22.03%, and their encapsulation efficiency was 97.24%. In vitro drug release in phosphate- buffered saline (pH =7.4) at 37.5°C exhibited a unique two-stage process, which could prove beneficial for patients with tumors and malignancies. MTT (3-[4,5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide) assay results showed that cis-DIDP released from cis-DIDP-loaded solid lipid nanoparticles had better inhibition activity than cis-DIDP that had not been loaded. © 2014 Chen et al.

In this paper, the Fe-rich phases in and their detrimental effect on aluminum alloys are summarized. The existence of brittle platelet β-Fe-rich phases lowers the mechanical properties of aluminum alloys. The methods to neutralize the detrimental effect of iron are discussed. The use of high cooling rate, solution heat treatment, and addition of elements such as Mn, Cr, Be, Co, Mo, Ni, V, W, Cu, Sr, or the rare earth elements Y, Nd, La, and Ce are reported to modify the platelet Fe-rich phases in aluminum alloys. The mechanism of the modification is briefly described. Technologies to remove iron from aluminum are reviewed extensively. The precipitation and removal of Fe-rich phases (sludge) are discussed. The dense phases can be removed by methods such as gravitational separation, electromagnetic (EM) separation, and centrifuge. Other methods include electrolysis, electro-slag refining, fractional solidification, and fluxing refining. The expensive three-layer cell electrolysis process is the most successful technique to remove iron from aluminum so far. © 2012 Copyright Taylor and Francis Group, LLC.

A strain ZZQ-6 capable of utilizing methyl parathion as the sole carbon sources and energy was isolated from soil. ZZQ-6 was identified as Paenibacillus macerans based on analysis of morphology, physiological and biochemical characters and 16S rRNA. The strain ZZQ-6 possessed excellent degradation performance for methyl parathion, the degradation rate of methyl parathion (50mg kg-1) in soil by strain ZZQ-6 could reach 99.9% after 7d. A multifunctional microbial manure was developed by using strain ZZQ-6. The microbial manure containing strain ZZQ-6 could be applied not only as fertilizer, but also as degradation preparation for treatment of methyl parathion and other organophosphorus pesticide residue. This study might provide theoretic basis and reference for prevention and control of methyl parathion or other pesticides pollution. It was also an important goal in this study to develop multifunctional microbial products for environmental protection and agriculture. © by PSP.

According to international standard, two platforms for bypass diode junction temper testing were constructed. one is steady state method, and the other is pulsed state method. Several times of tests were carried on in the platform. The results showed that junction temperature test had high uncertainty. Comparatively, transient state test method showed a high accuracy, while steady state method had a better repeatability and stability. In case of the reliability of the thermal resistance, RTHje, steady state method was suggested for junction temperature test. ©, 2015, Science Press. All right reserved.

Due to its special coordination ability to Cu(ii)-terpyridine complexes, a simple and straightforward visual recognition of p-DMAP out of its analogues has been realized via selective metallogel collapse. In combination with the selective gel collapse and the self-healing properties of metallohydrogel 1a, its potential application towards chemo-switch is also demonstrated. © 2015 The Royal Society of Chemistry.

Phenylethanolamine A (PEA), a β-agonist, was found to be illegally used as a growth promoter in pigs last year, causing Chinese government's great attention. Here, a sensitive electrochemical method was developed for detecting PEA by immobilization of gold nanoparticles (AuNPs), multiwalled carbon nanotubes (MWCNTs) and Nafion on the surface of a glassy carbon electrode (GCE). The Nafion/MWCNTs/AuNPs film was characterized by scanning electronic micrographs (SEM) and electrochemical impedance spectroscopy (EIS). The electrochemical behaviors of PEA at the modified GCE were investigated in detail. The synergetic effects of AuNPs, MWCNTs and Nafion amplify the electrochemical reduction signal of PEA, and result in high sensitivity for PEA determination. Under the optimal conditions, the electrochemical sensor shows a wide linear range of 0.01 to 10 (mol/L with a detection limit of 0.005 μmol/L. Moreover, the fabricated sensor presents high selectivity and long-term stability, which paves a new way for simple, rapid, sensitive detection of PEA. A novel electrochemical method was developed to detect PEA based on Nafion/MWCNTs/AuNPs/GCE. The synergetic effects of AuNPs, MWCNTs and Nafion amplify the electrochemical signal, achieving high sensitivity and a wide linear range of 0.01 to 10 μmol/L with a detection limit of 0.005 (mol/L.

A strain ZHU-1 capable of utilizing chlorpyrifos as the sole carbon sources and energy was isolated from soil. ZHU-1 was identified as Bacillus licheniformis based on analysis of morphology, physiological and biochemical characters and 16S rRNA. The addition of ZHU-1 to soil treated with chlorpyrifos resulted in a higher degradation rate than noninoculated soils, the degradation rate of chlorpyrifos (100 mg kg -1) could reach 99% or above after 14 days. The microbial manure added by strain ZHU-1 can be applied not only as fertilizer, but also in degrading chlorpyrifos residue in soil. This study may provide basis for prevention and control of pesticides pollution. © 2010 Academic Journals.

The microbial complex DSG-3 has also been developed into a microbial preparation successfully, and the degrading enzyme activities of new microbial preparation during straw degradation were very high, its degradation capability was on the same level of the commercial preparation N1. In addition, the storage stability of new microbial preparation was well and could be stored in usual room temperature. Therefore, the microbial complex DSG-3 preparation was considered as a potential candidate for commercial application.

With the development of the solar cell materials, the evaluation method of the novel solar cell is quite different from the traditional crystalline silicon solar cell. This paper will discuss the method for measuring the maximum power of the third generation solar cells. The standard test method was proposed to achieve the more accurate results. By testing the spectrum of solar simulator and the spectral response of solar cell, the mismatch factor under standard test conditions can be calculated, with standard AM1.5 G spectrum. The solar simulator intensity can be calibrated and the test error and uncertainty can be reduced through the mismatch factor to select the correct standard cell. © 2015 Taylor & Francis Group, London.

A facile online enrichment protocol has been proposed based on microfluidic droplets acting as an interface between a liquid chromatography separation system and detection systems of ESI-MS/MS and laser-induced fluorescence. Low-abundance species were successfully concentrated and analyzed in this system via droplet shrinkage. The proposed platform significantly increased the enrichment efficiency and detection sensitivity with reduced sample handling steps, short analysis time, and no cross-contamination. The presented system is universal, shows no discrimination, and is easily coupled with other separation and detection approaches. © 2013 American Chemical Society.
