Four new Zn(II) coordination polymers, {[Zn(L1)(4,4′-bipy)]·0.52CH3OH}n (1), {[Zn(L2)(4,4′-bipy)]·CH3OH}n (2), {[Zn3(L3)3(4,4′-bipy)0.5]·3CH3OH}n (3), {[Zn(L4)(4,4′-bipy)]·2CH3OH}n (4) (H2L1 = N-(1,3-diphenyl-4-propylene-5-pyrazolone) p-nitrobenzoylhydrazide, H2L2 = N-(1-phenyl-3-benzyl-4-propylene-5-pyrazolone) p-nit…
Harmonic distortion has garnered a lot of interest in the recent past due to the high advent of the non-linear electronic loads. Moreover, newer technologies including distributed generation and electric vehicles are anticipated to be part of the distribution systems at a mass scale in the near future. This makes it o…
SP1 protein as a new type of biological nanopore is described and is utilized to distinguish single-stranded DNA at the single-molecule level. Using the SP1 nanopore to investigate single molecule detection broadens the existing research areas of pore-forming biomaterials from unsymmetrical biological nanopores to sym…
We report an unusual homopolymer vesicle, which has a soft bilayer membrane composed of oligo(ethyleneoxy) side chains (OEs) with a gradually decreased packing density from the centre of the membrane to both margins, exhibiting thermo-responsive zeta potential and dispersibility and showing potential applications for…
The first di-protonated [FeFe] hydrogenase model relevant to key intermediates in catalytic hydrogen production is reported. The complex bearing the S-proton and Fe-hydride is structurally and spectroscopically characterized as well as studied by DFT calculations. The results show that the thiolate sulfur can accept p…
GaN-based light emitting diodes (LEDs) were grown on 1 mm × 1 mm patterned 2-inch and 6-inch Si (111) substrates by metal–organic vapour phase epitaxy (MOVPE). AlN interlayers with different thicknesses were introduced between the composition-graded AlGaN buffer layer and the GaN seed layer in different LED structures…
We have demonstrated that an organotemplate-free and seed-directed route has been successfully applied for synthesizing Fe-Beta zeolite with good crystallinity, high surface area, uniform crystals, and tetrahedral Al3+ and Fe3+ species. Catalytic tests for the direct decomposition of nitrous oxide indicate that the Fe…
A new lanthanoid porous coordination polymer, La-BTTc (BTTc = benzene-1,3,5-tris(2-thiophene-5-carboxylate)), was synthesized and structurally characterized to have densely aligned one-dimensional open metal sites, which were found to act as strong Lewis acid sites after the removal of the coordinated solvent.
To establish a biotechnological system to convert CO2 into methane, we are trying to develop a new CO2 bio-conversion technology based on “electromethanogenesis”, a new bio-electrolysis reaction using microbially-catalyzed electrode. In this study, we characterized bio-electrochemical properties of electromethanogenic…
Development of a safe and effective method for gene delivery to hepatocytes is a critical step toward gene therapy for liver diseases. Here, we assessed the parameters for gene delivery to the livers of large animals (pigs, 40-65 kg) using an image-guided hydrodynamics-based procedure that involves image-guided cathet…
Nitrogen-doped TiO2 thin films were prepared by spin coating on glass substrate. Different amount of nitrogen doped in TiO2 matrix was 0, 3 and 10%. As-obtained films were annealed at 400 °C for 2 h. The optical and photocatalytic properties of N-doped TiO2 thin films were analyzed via UV-Vis spectrophotometry. The ch…
The effect of the calcination temperature on the physicochemical properties and catalytic performance of a plasma treated Ni–Co/Al2O3–ZrO2 nanocatalyst was studied in the dry reforming of methane. According to the XRD, FESEM, TEM, EDX dot-mapping, BET and XPS characterizations, the optimum calcination temperature was…
A metal-based fluorescent probe for H2O2, named MBFh2, releases a highly fluorescent resorufin in the seconds time scale even in the presence of 5 μM H2O2. The use of MBFh2 enabled the visualization of intracellular H2O2 that was generated after stimulation of the epidermal growth factor.
The N-oxide-4,4′-bipyridine (bp4mo) ligand has been rarely used in coordination or supramolecular chemistry. Depending on experimental conditions in the bp4mo/BiX3 (X = Cl, Br) system, several compounds, in which the degree of protonation of bp4mo (τ = H/bp4mo) varies, have been stabilized. In acidic conditions, eithe…
Thermochemical CO2 splitting was carried out over Ni-, Fe-, Mg- and Mn-doped ceria/zirconia solid solutions, where the sample was thermally reduced at 1400 °C under inert atmosphere followed by the re-oxidization of CO2 to generate CO at 1100 °C in the subsequent step. Compared with the undoped sample, all the doped c…
We demonstrated a simple and green chemical method to obtain Michael adducts and their derivatives by using GO as a phase transfer catalyst with different kinds of bases in water and dichloromethane, and we also used GO multiple cycles almost without reduction in reaction yields.
A sustainable V(V) and Mo(VI) catalysed two-phase procedure for bromination of toluene under quite mild conditions is proposed; H2O2 is the primary oxidant and KBr is the bromine source; metal precursors are commercially available salts. The reaction is efficient without any additional solvent. By using PhCH3 as a sol…
The nonlinear optical (NLO) and optical limiting (OL) properties of three new structures of organic NLO guest-host Poly(N-vinylcarbozole)/disperse orange 3 (PVK/DO3), PVK/disperse orange 13 (PVK/DO13), and PVK/disperse orange 25 (PVK/DO25) as a solution at different concentrations and as a thin-film sample are studied…
Organic photovoltaic device efficiencies can be greatly improved by controlling the morphology of donor and acceptor domains in the active layer. Connectivity within donor and acceptor domains is of key importance in order to direct charge carriers efficiently to the electrodes. We report here on self-assembly pathway…
A Ni/SiO2 catalyst was prepared by the plasma decomposition of a nickel precursor via dielectric barrier discharge (DBD). The obtained Ni/SiO2 catalyst shows an enhanced H2S resistance for methanation of syngas (CO + H2). The plasma decomposition has a significant influence on the structural property of Ni/SiO2. The p…
