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.

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.

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.

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.

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.
