A silane-based adhesive formulation, used in the aerospace industry, was studied using sub-nanometre spatially-resolved energy loss spectroscopy, as a function of the concentration of silane used in the adhesive. The changes in the relative oxygen concentration and the occupancy of p-type states in the oxygen density of states reveal the existence of a composite layer between the aluminium and ...
This paper is to study the effect of surface coating and silane hydrophobic agents for high performance concrete durability in a marine environment of tidal zone and splash zone by exposure test in JiaoZhou Bay. The results indicated that surface coating had good protection and coating quality after a 5-year period and the adhesive strength with concrete surface was more than 2.5 MPa. Surface c...
objective: repair of an indirect restoration is usually preferred over its replacement. this study aimed to evaluate the effect of silane in different surface preparation techniques on the bond strength of direct to indirect composite resin. methods: for this in vitro experimental study, 48 indirect composite cubes were fabricated, divided into 4 groups of 12 and subjected to the following pr...
Microcrystalline silicon solar cells with AM 1.5 conversion efficiency above 5 % have been deposited at deposition rates in excess of 10 Å/s. This is achieved by VHF-GD at an excitation frequency of 130 MHz. By increasing the plasma power at a dilution ratio of 7.5 % silane/(silane+hydrogen) there first appears a morphological transition from a-Si:H to μc-Si:H and then an increase in deposition...
By the introduction of an organic silane self-assembled monolayer, an interface-engineering approach is demonstrated for hole-conductor-free, fully printable mesoscopic perovskite solar cells based on a carbon counter electrode. The self-assembled silane monolayer is incorporated between the TiO2 and CH3NH3PbI3, resulting in optimized interface band alignments and enhanced charge lifetime. The ...
Bigels are unique two-phase systems that have recently been presented as a structured method for active ingredient application. The purposes of the current study were to develop and characterize bigel formulations containing loxoprofen. They benefits both hydrogel organo-gel. In order enhance penetration, pluronic lecithin was added form organo-gel, HPMC hydrogel, which properly hydrates stratu...
Background Bonding to silica-based ceramics requires micro mechanical (hydrofluoric-acid, HFetching) and chemical (silane) coupling [1–5]. The HF-etching provides dissolution of Abstract Statement of problem: The hydrofluoric acid (HF) is able to promote selective dissolution of the glassy phase in silica-based ceramic. However, the etching leaves insoluble silica-fluoride salts in the surface ...
By A. J. NORONHA, m.d., Hoiiy. Physician, J. J. Hospital, Bombay. TwEXvE bottles were supplied for trial in my wards of the preparation named Bazogen, purporting to consist of the extract of Spleen, Pancreas, Thyroid, and Adrenal. The supply of the drug was limited, and a fair trial could not be given. The accompanying charts show that a drop in the temperature occurs even in severe cases with ...
Sorption of organic molecules to mineral surfaces is an important control upon the aquatic carbon (C) cycle. Organo-mineral interactions are known to regulate the transport and burial of C within inland waters, yet the mechanisms that underlie these processes are poorly constrained. Streamwater contains a complex and dynamic mix of dissolved organic compounds that coexists with a range of organ...
