The films of ZnO–SnO2 system were deposited on glass substrates by simultaneous dc magnetron sputtering apparatus, in which ZnO and SnO2:Sb (Sb2O5 3 wt % doped) targets faced each other. substrate temperatures maintained at 150, 250, 350 °C, respectively. As an experimental parameter, current ratio δ=IZn/(IZn+ISn), corresponds to target (IZn) divided the sum currents (IZn+ISn), was adopted. Amorphous transparent appeared for 0.50⩽δ⩽0.73, could be correlated compositions as...
Most heteroaryl selenides and diselenides are biologically active, with some reported to act as antioxidants show activities that medicinally relevant; hence, the development of efficient methods for their synthesis is an important objective. Herein, a simple method bearing imidazo[1,2-a]pyridine rings anticancer activity described. The double C-H selenation Se powder was catalyzed by CuI (10 mol %) ligated 1,10-phenanthroline at 130 °C under aerobic conditions. or were prepared almost...
The combination of X-ray analysis and laser desorption ionization by using crystalline sponge will be a promising method to determine guest structures.
Hollow CeO2 particles with three types of morphologies (rod, rhombus, and dumbbell) were synthesized by retention the morphology Ce(OH)CO3 precursors during interfacial reactions aqueous hydrogen peroxide solution. The wall areas hollow comprised crystalline nanoparticles. pH solution played a crucial role in formation structure. mechanism underlying structure was also evaluated. structures rod-shaped maintained even after calcination at 1000 °C, although collapsed 1250 °C. Similar using...
誘導結合型プラズマ質量分析法（ICP-MS），誘導結合型プラズマ発光分析法（ICP-AES）を利用した下水汚泥中多元素定量法を開発した．試料の溶液化はマイクロ波酸分解法又はアルカリ融解法で行い，元素測定にはICP-MS及びICP-AESを用いた．分析値の評価には，Institute for Reference Materials and Measurements（ヨーロッパ共同体標準物質計測研究所，IRMM）より頒布されている下水汚泥標準物質（BCR-144R）を使用した．アルカリ融解法では，Zn，Cu，Pb，Ni，Co，Cdで保証値より定量値が低くなった．この濃度低下はZn，Pb，CoとCdでは揮発，Cu及びNiではPtるつぼへの合金形成が主な要因であることが分かった．また，Nb，Ta，Hfの溶解にはマイクロ波酸分解法及びアルカリ融解法双方において溶解液へのフッ化水素酸の添加が必要であった．そこで，徳島市で採取した下水汚泥実試料をマイクロ波酸分解/ICP-MS，ICP-AES法により分析した結果，計44元素の定量が可能であった．
The copolymerization of p-tert-butoxystyrene (TBOSt) (M1) and di-n-butyl maleate (DBM) (M2) with dimethyl 2,2′-azobisisobutyrate (MAIB) in benzene at 60°C was studied kinetically by means ESR spectroscopy. monomer reactivity ratios were determined to be r1 = 2.3 r2 0 a curve-fitting method. system found involve ESR-observable propagating polymer radicals under practical conditions. apparent rate constants propagation (kp) termination (kt) different feed compositions ESR. From the...
Al-doped In2O3-ZnO films were developed and the influence of Al doping in electrical optical properties was investigated. Amorphous homologous phases appeared with increasing δ=Zn∕(Zn+In) ratios. The carrier generation mechanism is discussed for these films. Native oxygen defects are primary donors Then low resistivities 2–4×10−4Ωcm attained within a narrow range amorphous phase film. Two wt % (percent by weight) Al2O3-doping decreased resistivity to 1.5–2.1×10−4Ωcm. At 3 4 Al2O3, film...
The vaporization process of the monoatomic state mercury [mercury (0)] in acidic solution is investigated. determination vaporized (0) performed by a flameless atomic absorption method. It was found from experiments that based on oxidation reaction to (I) oxidizing agents such as ferric and silver ions, disproportionation solution; complex-forming anions halides, cyanide sulfide markedly suppressed order suppression effect with halides is; I− > Br− Cl− F−. Key Words:...
Abstract The behavior of mercury vapor during irradiation by a lamp is investigated. Using the flameless atomic absorption technique for determination, it was found that when in an inert gas irradiated lamp, signal decreased rapidly and may be restored heating to 70°C. These phenomena indicate products quartz tube are deposited on tube, dissociated into mono-atomic state upon heating.
We obtained 202.5-MHz 31P-nuclear magnetic resonance (NMR) spectra of isolated perfused rat lungs, degassed and inflated, lung extract. The included those ATP, ADP, phosphocreatine (PCr), inorganic phosphate (Pi), phosphomonoesters, phosphodiesters, a broad component due to the membrane phospholipids. line width at one-half peak height for beta-ATP was 1.0 ppm 1.2 inflated lung. This suggests that air-water interfaces in lung, which produce proton NMR broadening, do not act prominently...
Structural and transparent conducting properties of amorphous Zn-In-O films deposited by simultaneous sputtering ZnO In 2 O 3 targets facing each other were reviewed. Post-annealing under the reductive gas flow was effective on improving unevenness films.
Three linear diphenylene compounds having one, two, and three double bonds, respectively, were encapsulated in a nano-porous coordination complex called “crystalline sponge” (CS). The presence of t...
