The effects of ceramic additions on the commercial aluminum alloy A356 used as anode for Al-air battery in alkaline electrolyte were examined by electrochemical tests, discharge and corresponding microstructure observations. The results indicate that the anodes with SiC or AlO additive showed high corrosion rate and low-anode efficiency and low-capacity density. Corresponding microstructures indicated that the various electrochemical behaviors are attributed to ceramic particulates which changed the eutectic precipitation distribution and introduced extra interfaces.

dimethylaminoethyl methacrylate (dMAEMA)-grafted graphene hybrid materials (GO-PdMAEMA) were fabricated using gamma irradiation at ambient temperature. The morphology and structure of GO-PdMAEMA were characterized by Fourier-transform infrared spectroscopy, X-ray photoelectron, thermogravimetric analysis, differential scanning calorimetry and X-ray diffraction. It was confirmed that PdMAEMA was grafted on the surface of graphene sheet. The grafting yield for the samples increased

Biodegradable nanostructures displaying aggregation-induced emission (AIE) are desirable from a biomedical point of view, due to the advantageous features of loading capacity, emission brightness, and fluorescence stability. Herein, biodegradable polymers comprising poly (ethylene glycol)-block-poly(caprolactone-gradient-trimethylene carbonate) (PEG-P(CLgTMC)), with tetraphenylethylene pyridinium-TMC (PAIE) side chains have been developed, which self-assembled into well-defined polymersomes. The resultant AIEgenic polymersomes are intrinsically fluorescent delivery vehicles. The presence of the pyridinium moiety endows the polymersomes with mitochondrial targeting ability, which improves the efficiency of co-encapsulated photosensitizers and improves therapeutic index against cancer cells both in vitro and in vivo. This contribution showcases the ability to engineer AIEgenic polymersomes with structure inherent fluorescence and targeting capacity for enhanced photodynamic therapy.

Quantitative microstructure and fatigue life of B319 casting alloys

rare Metals 2017年第10期36卷 780-791页

作者： Yue Shen Xiao-Shan Liu Guo-Qiu He dan-dan Tian Qi-Gui Wang Shi-Quan Lv School of Materials Science and Engineering Tongji University Shanghai 201804 China Shanghai Key Laboratory for R&D and Application of Metallic Functional Materials Shanghai 201804 China Mat Technol Global Powertrain Engn Gen Motors Co Pontiac MI 48340 USA

In this study, the microstructure of B319 casting alloys and effects of five different casting conditions on microstructure were studied. Multi-scale microstructure was quantified in terms of secondary dendrite arm spacing （SdAS）, and Si particle size and aspect ratio. The effects of SdAS, Si aspect ratio and size on fatigue life were analyzed. The results indicate that the size and aspect ratio of Si particles are a function of SdAS which is dependent on cooling rate during solidification. The fatigue life decreases with SdAS increasing as SdAS is smaller than 30 pm while it increases with SdAS increasing as SdAS is larger than 60 ~tm. In addition, the fatigue life decreases with Si aspect ratio and size increasing at the same SdAS. Moreover, SdAS and Si particles have also influence on fatigue fracture, such as the area of cracks propagation region and the roughness of fatigue fracture. The cracks propagation area is smaller, and the fatigue fracture is similar to tensile fracture with larger SdAS. Besides, the longitudinal section of fatigue fracture is rougher with large SdAS and elongated Si particles.

Highly Efficient random Terpolymers for Photovoltaic applications with Enhanced Absorption and Molecular Aggregation

A series of copolymers, based on benzo[1,2-b：4,5-b＇]dithiophene （BdT） as the electron donor and 2,1,3- benzothiadiazole （BT）/diketopyrrolo[3,4-c]pyrrole （dPP） as the electron acceptors, were synthesized for highly efficient polymer solar cells. By changing the BT/dPP ratio in the conjugated backbone, the absorption, energy levels, molecular aggregation and carrier mobility could be finely tuned. With increased dPP content, the absorption range was extended to the longer wavelength region with narrower bandgaps. The highest occupied molecular orbital （HOMO） levels were also raised up and the molecular aggregation was enhanced. The balance of these factors would afford a remarkable device performance enhancement. polymer P3 with BT：dPP = 0.7：0.3 （molar ratio） exhibited the highest power conversion efficiency （PCE） of 9.01%, with open circuit voltage （Voc） = 0.73 V, short current density （Jsc） = 18.45 ***-2, and fill factor （FF） - 66.9%. The PCE value was improved by 48.7% compared to P1 and by 117.6% compared to P7, respectively, indicating a great potential in photovoltaic application.

We disclose herein an atroposelective synthesis of novel bridged biaryls containing medium-sized rings via N-heterocyclic carbene organocatalysis. The reaction starts with addition of the carbene catalyst to the aminophenol-derived aldimine substrate. Subsequent oxidation and intramolecular desymmetrization lead to the formation of 1,3-oxazepine-containing bridged biaryls in good yields and excellent enantioselectivities. These novel bridged biaryl products can be readily transformed into chiral phosphite ligands. Preliminary density function theory calculations suggest that the origin of enantioselectivity arises from the more favorable frontier molecular orbital interactions in the transition state leading to the major product.
