Noncovalent interactions have been used to modify the binding properties of two-armed diketopiperazine receptors by ionic self-assembly and induced the formation of liquid-crystalline (LC) materials. The properties of the LC material were in turn modified by binding to a selectively recognized peptidic guest.
Gold quantum dots (AuQDs) were synthesized and electrostatically conjugated to goat-derived anti-human IgG for the purpose of detecting human IgG in solution over a broad range of concentrations. The system is able to detect human IgG by linear fluorescence quenching over a micromolar to nanomolar concentration range.…
The objective of the present study is to investigate the effect of electrospun nanofiber reinforcement on the properties of commercially available, hyperbranched polymer modified (Hybrane, 0.3 wt.% DSM) dental formulations. The emergence of functionalized nanoscale reinforcements having large surface area (hundreds of…
Polyether chains have been successfully grafted onto the interlayer surface of a Dion–Jacobson-type layered perovskite, HLaNb2O7·xH2O, by a reaction between an n-decoxy-derivative of HLaNb2O7·xH2O and CH3(OCH2CH2)mOH (1 ≤ m ≤ 4). After the reaction, the interlayer distance decreases from 2.73 nm to 1.58 (m = 1), 2.07…
The broader applicability of local hardness, [eta(r)] as a reliable intermolecular reactivity descriptor primarily depends on the removal of its 1/N (N, total number of electrons of the system) dependence. In this article an attempt is made to illustrate the problem of evaluating eta(r) by using rho(r) (the electron d…
Using thermogravimetric analysis (TGA), the thermal behavior of sisal fibers and sisal/polyester composites, fabricated by resin transfer molding (RTM), has been followed. Chemical treatments have been found to increase the thermal stability, which has been attributed to the resultant physical and chemical changes. Sc…
Na2[Mo3(μ3-S)(μ-S)3(Hnta)3] serves both as a reducing and a capping agent in the synthesis of Au nanoparticles in water at room temperature in a “fully green chemistry-type process”, thus avoiding the usual two-step preparation of thiolate-monolayer-coated gold nanoparticles. The nanoparticles were characterized by TE…
The synthesis of the first gallium(III)-based liquid crystal has been achieved grafting around the metal centre two chelating 2-methylquinolin-8-olate anions and one monodentate 3,4,5-tris(hexadecyloxy)benzoyloxy ligand, allowing the resulting complex to be a soft luminescent material with the typical high quantum yie…
This work presents a detailed study of poly(neopentyl methacrylate-co-ethylene glycol diacrylate) [P(npMA-co-EGDA)] copolymer, which was selected for study from possible combination of 20 vinyl monomers and 4 divinyl crosslinkers as a candidate for sacrificial layer materials for the fabrication of air-gap structures.…
The unique molybdenum oxide-based nucleophilic porous capsule/artificial cell [{(MoVI)MoVI5O21(H2O)6}12{MoV2O4(SO4)30}]72-, according to an X-ray crystallographic study, traps [Al(H2O)6]3+ complexes above the pores while interacting with the latter via hydrogen bonds; this is supported by 27Al NMR studies of the inter…
In order to improve the blood compatibility of the commonly used blood-contacting biomaterial poly(ethylene terephthalate) (PET), in this study PET films were chemically modified with L-arginine (L-Arg) by a three-step-procedure using glutaraldehyde (GA) as a cross-linker. The composition and chemical structure of PET…
New insight is provided by a combined theoretical and simulational approach regarding the effects of structural characteristics of the constituents, on the overcharging phenomena in complexes formed by hyperbranched polymers with linear polyelectrolytes.
An oligo(p-phenylenevinylene) capped on one end by a monotopic DAD-type triple hydrogen-bonding module shows distinct optical properties as well as self-organization behavior upon complexation with cyanurates with different numbers of ADA-type triple hydrogen-bonding sites.
The alkyl spacer was lengthened in heterogenizing a Rh-P complex into mesoporous silicate SBA-15 to increase the immobilized catalyst activities in 1-octene hydroformylation.

Inorganic superhydrophobic, low-surface energy silica coatings have been prepared using sol–gel processing with tetraethoxysilane and trifluoropropyltrimethoxysilane as precursors. When trifluoropropyltrimethoxysilane was incorporated into silica, hydrophobic trifluoropropyl groups were present on the surface, yieldin…
The antifugal activities of aqueous extract of Calotropics procera was determined against Epidermophyton flocosum and Tricophyton gypseum using agar diffusion techniques. The crude extract of C. procera showed activity on E. flocosum and T. gypseum at 4.0 mg/ml. The result of minimum inhibitory concentration (MIC) was…

在这研究，减少 NOx 和微粒的努力有关系(下午) 从两个都使用 NOx overanAg/Al2O3 催化剂和 biodiesel-ethanol-diesel 燃料的乙醇选择的催化减小(SCR ) 的一个柴油发动机的排出物相配(柴油机) 在一张引擎凳子上，测试被讨论。与柴油相比，柴油机的使用由于下午的可溶的器官的部分(SOF ) 的增加增加了下午排出物 14% ，但是它极大地减少了 Bosch 烟数字由 60%80% 根据从欧洲静止周期(转换字符) 的 13 模式测试的结果测试。SCR 催化剂在由乙醇的 NOx 减小是有效的，并且 NOx 变换是约 73% 。全部的烃(THC ) 和公司排出物在 NOx 过程的 SCR 期间显…
THE POLYMORPHS OF CALCIUM CARBONATE -AN EASY SYNTHESIS OF ARAGONITE. Aragonite is a metastable polymorph of calcium carbonate. The calcareous exoskeletons of some organisms like corals or molluscs consist essentially of aragonite. The questions of how, and why these organisms prefer the thermodynamically unstable arag…
