The reaction of Zn(II) and 4,4′,4′′-(benzene-1,3,5-triyl-tris(benzene-4,1-diyl))-tribenzoic acid (H3BBC) without or with the presence of 2-amino-1,4-benzenedicarboxylic acid (NH2-H2BDC) under solvothermal conditions leads to the generation of two novel Zn(II) coordination polymers, [Zn(BBC)(H2O)2](Me2NH2)·12DMF (1) an…
Poly(ethylene glycol-block-2-hydroxyethyl methacrylate-block-tert-butyl acrylate) (PEG-b-PHEMA-b-PtBA) triblock copolymer was synthesized by the sequential atom transfer radical polymerization (ATRP) of HEMA and tBA using an ATRP initiator terminated PEG (PEG-Br) as the macroinitiator. Azide groups were introduced to…
Methylation of the silicon surface through a chlorination-alkylation method has been used to improve the electronic properties of silicon. Upon alkylation of the surface, an increase in the minority carrier recombination lifetime and the surface photovoltage is observed, in line with an increase in surface charge. A l…
We report the simultaneous measurement of temperature and humidity by analysing square wave voltammetric responses of two ferrocene derivatives, decamethylferrocene (DmFc) and 1,2-diferrocenylethylene (bisferrocene, BisFc) in 1-(2-methoxyethyl)-1-methyl-pyrrolidinium tris(pentafluoroethyl)trifluorophosphate ([Moepyrr]…
An enzymic method to protect selected amino group of lysine has been reported. This reaction proceeds smoothly under room temperature with high regioselectivity (up to 99%) and high yields (up to 90%). This work will pave the way for simple and selective protection of amino group of lysine in industry.
Reactions of transition metal(II) salts with a rigid 3-fluorophthalic acid (H2Fpht) and a flexible ligand, 1,3-bis(4-pyridyl)propane (bpp), afforded a series of coordination polymers, [Cu(Fpht)bpp]·0.5H2O (1), [Cu(Fpht)bpp·H2O] (2), [Cd(Fpht)bpp·H2O]·H2O (3), [Co(Fpht)bpp·H2O] (4) and [Ni(Fpht)bpp·H2O] (5). The five c…
The rapid and massive formation of a foamy precipitate while reacting zinc acetate (Zn(Ac)2) and triethanolamine (TEA) in proper conditions led to an unravelled complex and a molecular tetra-metallic zinc cluster: their synthesis was optimised and they were characterised by single crystal X-ray diffraction. The struct…
An enantioenriched three-dimensional quartz-type framework {[Ni(1.5)(tzdc)(H(2)O)(3)]·3H(2)O}(n) (H(3)tzdc = 4H-1,2,4-triazole-3,5-dicarboxylic acid) possessing chiral channels is obtained through spontaneous asymmetric crystallization without any enantiopure additive.
We present an application of a selective time-dependent density-functional theory (TDDFT) scheme to a model for a dye-sensitized solar cell (DSSC) with a perylene sensitizer dye on a TiO2 nanoparticle model. In an earlier study on this system [De Angelis, Chem. Phys. Lett., 2010, 493, 323], it was reported that a larg…
Core-shell assemblies of nanocrystals of sumanene (shell) and sumanenetrione (core) resembling onigiri (filled Japanese rice balls) were fabricated by stepwise reprecipitation. Optical properties of the onigiri-type assemblies showed that emissions from the core sumanenetrione nanocrystals were amplified through energ…
In this work, we report on product energy distributions for methyl radicals produced by UV photooxidation of a set of structurally related carbonyl molecules, R(CO)CH(3) (R = H, CH(3), C(2)H(5), C(6)H(5)), adsorbed on a TiO(2)(110) surface. Specifically, laser pump-probe techniques were used to measure the translation…
The effectiveness of ultrasound in washing textiles was investigated using polyester woven fabrics soiled with model contaminants such as oleic acid/Sudan III mixture and carbon black. The soiled and original fabrics were washed together in aqueous solutions with shaking or frequency-modulated ultrasound. The detergen…
Stimuli-responsive gels that can change their volumes drastically in response to various external physical and chemical stimuli have been of much interest due to their various applications. Herein, novel stimuli-responsive gels were achieved through the complexation between anion receptors and the chloride anion of po…
We show that monodisperse iron oxide nanoparticles in the size range of 6–17 nm, coated with brush-like layers of polystyrene or polyisoprene of different molecular weights, form well-defined lyotropic liquid crystalline phases. The lyotropic phase behaviour was investigated by synchrotron small-angle X-ray scattering…
A conformational analysis of the Pt(dap)Cl2 complex (dap = 1, 3‐diaminopropane) was performed by vibrational spectroscopy (FTIR, Raman, and INS), coupled to quantum mechanical methods within the density functional theory (DFT) and effective core potential (ECP) approaches. A complete spectral assignment of the system…
We investigated the electrochemical behavior of hemoglobin by glassy carbon electrode modified with Mn(2)O(3)-Ag nanofibers. The Mn(2)O(3)-Ag nanofibers were used as facilitator electron transfer between Hb and glassy-carbon-modified electrode. The Mn(2)O(3)-Ag nanofibers are studied by scanning electron microscopy (S…
The ionic liquid (IL) 1-(2-hydroxyethyl)-3-methylimidazolium acetate ([C2OHmim][OAc]) was designed and used to provide a compatible IL-cellulase system in which lignocellulosic biomass can be effectively solubilized and activated, while maintaining the high stability and activity of the cellulase. In this study, we in…
We prepared Li(Mn 1/3 Ni 1/3 Co 1/3-x Al x )O 2 by a solution method, and then investigated the electrode characteristics and average and local structures. From the charge-discharge cycle tests, it was found that Li(Mn 1/3 Ni 1/3 Co 2/9 Al 1/9 )O 2 exhibited a worse cycle performance than Li(Mn 1/3 Ni 1/3 Co 1/3 )O 2…
A controllable method for coating a dense layer of poly-CuTAPc polymer on the surface of silicon nanowire array was reported and it is shown that the coating of poly-CuTAPc can effectively enhance both the photocatalytic hydrogen generation efficiency and the operation stability.
This paper is focused to study Sm2FeTaO7pyrochlore-type compound as solar photocatalyst for the degradation of indigo carmine dye in aqueous solution. Sm2FeTaO7was synthesized by using conventional solid state reaction and sol-gel method. X-ray diffraction results indicated that Sm2FeTaO7exhibit a monoclinic crystal s…
