An efficient method was developed to encapsulate water insoluble organic particles of Sudan red III (SR) in aqueous suspensions by using a polymerizable cationic gemini surfactant, 1,3-bis(N,N-dimethyl-N-cetylammonium)-2-(propylacrylate dibromide) (AGC16). The AGC16 coated SR microcapsules (AGC16@SR) were prepared by absorption of AGC16 on the surface of SR, followed by in situ homopolymerizati...

We report the synthesis of a Au44(SR)28 nanocluster (SR = 4-tert-butylbenzenethiolate). Based on the structural rules learned from the known Au28(SR)20 and Au36(SR)24 structures, we propose a plausible structure for Au44(SR)28, which is predicted to comprise a six-interpenetrating cuboctahedral Au36 kernel protected by four dimeric staples and sixteen bridging thiolates, i.e. Au36[Au2(SR)3]4(SR...

A novel cobalt-free Cu1.2Mn1.8O4 spinel coating is prepared and evaluated for the metal interconnect of solid oxide fuel cell. Mn-35Cu and Co-35Mn alloy coatings are deposited on 430 SS substrate and then in-situ oxidized in air at 750 ◦C for 100 h. XRD results confirm that Cu1.2Mn1.8O4 spinel with some Mn2O3 is formed, and the average thickness of the coating is 70–80 μm according to cross sec...

La1-xSrxAlO3 (x=0 to 0.4) perovskite materials were synthesized by the reverse strike co-precipitation method and their soot oxidation activity was evaluated. All the catalysts synthesized were characterized using XRD, BET specific surface area, FESEM and XPS techniques. As analyzed by XRD, La1-xSrxAlO3 <...

Semantic relatedness (SR) measures form the algorithmic foundation of intelligent technologies in domains ranging from artificial intelligence to human-computer interaction. Although SR has been researched for decades, this work has focused on developing general SR measures rooted in graph and text mining algorithms that perform reasonably well for many different types of concepts. This paper i...

In recent studies the Sr/Ca ratio of coccolithophore calcite was used as a proxy for past coccolithophore growth and calcification rates. Since Sr and Ca concentrations in seawater have not remained constant through time, interpretation of Sr/Ca data from the coccolith-dominated sedimentary record requires knowledge about the incorporation of seawater Sr into coccolith calcite during coccolitho...

epoxy powder coatings containing zinc aluminum phosphate (zap) and zinc phosphate (zp), which are the 2nd and 1st generation of phosphate-based pigments respectively, were applied to the surface of mild steel sheets. the anticorrosive performances of the coated samples were studied using electrochemical impedance spectroscopy (eis). cathodic disbonding resistance and the adhesion performance of...

BACKGROUND Immobilizing bioactive molecules and osteoconductive apatite on titanium implants have investigated direct ossification. In this study, hydroxycholesterol (HC) was immobilized with apatite on titanium through simply adsorption or sandwich-like coating. Three kinds of hydroxycholesterol were chosen to induce ossification: 20α-hydroxycholesterol (20α- HC), 22(S)-hydroxycholesterol (22(...

Lithium iron borate (LiFeBO3) is a promising cathode material due to its high theoretical specific capacity, inexpensive components and small volume change during operation. Yet, challenges related to severe air- and moisture-induced degradation have prompted the utilization of a protective coating on the electrode which also improves the electronic conductivity. However, not much is known abou...

low water-wettability and oxidation resistance of graphite have limited its application in carbon containing refractory castables. the aims of this study were improvement of water-wettability and the oxidation resistance of natural flaky graphite by applying an oxide coating on its surface. to develop the coating, magnesium aluminate spinel sol was formulated via a citrate-nitrate route and gra...
