Bonding strength was fundamentally determined by the degree of fragmentation of the oxide films, through which the formation of IMCs can be initiated due to the direct contact of the metal surfaces to be bonded. The extent of fracture the oxide layer was strongly HIF activation influenced by the level of ultrasonic power, as at its high level alumina fragmentation becomes pervasive
resulting in contiguous alloy interfaces and robust bonds. The IMCs formed at the interfaces were identified as Al4Al and AuAl2 with a thickness of 150-300 nm. The formation mechanism of such IMCs was explained by the effective heat of formation theory. (C) 2010 American Institute of Physics. [doi:10.1063/1.3514005]“
“Human SP110 plays an important role in resisting intracellular pathogens, and hence has become an important drug target for preventing intracellular pathogen diseases, such as tuberculosis, hepatic veno-occlusive disease, and intracellular cancers. Unfortunately, so far little is known about the interactions of SP110 with the other proteins in a cell, which is considered to be the key for revealing
its action mechanism and mediated pathway. Using both the genetic and structural analyses MLN8237 inhibitor as well as the segment-docking approach, we have identified two proteins: the human remodeling and spacing factor 1 (RSF1) and the activating transcription factor 7 interacting protein (ATF7IP). They are very likely interacting with human SP110 during the process of viral infections. Owing to the close relationship of RSF1 with the chromatin remodeling and ATF7IP with the chromatin formation, it is logical to infer that human SP110 may be involved in the chromatin RepSox remodeling and formation as well. These findings may provide useful insights into the development of new drugs for treating and preventing intracellular pathogen diseases.”
“A large scale heterostructure array of ZnO nanowires/silicon nanoporous pillar array (Si-NPA) was prepared by a self-catalytic thermal evaporation and vapor-phase transport method, and an ultrahigh field emission current density of 1.55 mA cm(-2) was obtained under
an operating electric field of 4.0 V mu m(-1), with a low turn-on field of 1.65 V mu m(-1). The enhancement factor calculated according to the Fowler-Nordheim theory was similar to 3141. The excellent field emission performance was attributed to the unique structure of ZnO/Si-NPA, especially the formation of ZnO nanowires on regular Si pillar array. Our work indicated that ZnO/Si-NPA might be an ideal candidate cathode of potential applications in flat panel displays and high brightness electron sources. (c) 2010 American Institute of Physics.

“Thevetia peruviana (Pers.) K. Schum. seed oil was used to make a surface coating with antifungal, antibacterial and anti-termite properties. The paint exhibited inhibitory activity against Escherichia coli, Staphylococcus aureus, Bacillus subtilis and Candida albicans in a concentration dependent manner.
