CSP reflectors are a key component for CSP technology and are characterized by their specular reflectance (SR), the degree to which a mirror is capable of transferring directed radiation to a target receiver surface. The accumulation of dust on the surface of the reflectors can decrease the ability of their mirrors in…
The oxygen chemical potential of dense Nd2NiO4+δ thin films on Zr0.92Y0.08O1.96 electrolyte was investigated by operando X-ray absorption spectroscopy (XAS) measurements. Operando XAS at the Ni K-edge was measured under an applied voltage and various oxygen partial pressures at high temperature to simulate the operati…
A model comprised of a rate equation for polymerization and cross-linking reaction and the time-dependent Ginzburg–Landau equation for spinodal decomposition was utilized to describe reaction-induced spinodal decomposition (RISD). The effects of initial composition, curing temperature, and scaled diffusion coefficient…
Laboratory-scale anaerobic fermentation was performed to obtain lactic acid from lactose, using five lactic acid bacteria: Lactococcus lactis, Lactobacillus bulgaricus, L. delbrueckii, L. plantarum, and L. delbrueckii lactis . A yield of 0.99 g lactic acid/g lactose was obtained with L. delbrueckii , from which a fina…
Substituted M-type Hexaferrites are ferrimagneticmaterials, which are hard ferrites. In the current study, Aluminum substituted Hexaferrite samples, with composition CaFe12-xAlxO19 (x=3,x=4), have been prepared by Solution combustion synthesis using Metal Nitrates. The powders were characterized with XRD, TEM, SEM, an…
Electron spin resonance (ESR) and photoluminescence (PL) techniques were utilized to investigate the gamma radiation induced changes occurring in the Trombay research reactor nuclear waste glasses. Fe and Eu were doped in the glass samples which acted as local probes. From these studies it was seen that upon irradiati…

Rapid cell growth and rapid recovery of intact cultured cells are an invaluable technique to maintain the biological functions and viability of cells. To achieve this goal, thermoresponsive polystyrene (PS) nanofibrous mat was fabricated by electrospinning of PS solution, followed by the graft polymerization of thermo…
Thiosalicylic acid (TSA) was used as a stabilizer to synthesize CdTe quantum dots (QDs) in aqueous solution. The reaction conditions, such as refluxing time, precursor concentrations, the molar ratio of reactants, and the pH value, were investigated. Under optimized conditions, the photoluminescence quantum yields (PL…
In this research, we studied the effect of acid hydrolysis temperature on the crystallinity of cellulose produced from empty fruit bunch (EFB). The hydrolysis temperature was studied from 120 to 140 C at a fixed time and sulfuric acid, H 2 SO 4 concentration which were 1 h and 1% (v/v) respectively. X-ray diffractomet…
La0.67Ca0.33MnO3 perovskite-type manganite was synthesized by high-energy ball milling raw oxides of La2O3 (purity 99.9%), CaCO3 (purity > 99%), and MnO (purity > 99%). The ratio of ball and powder weight was 10:1 and the rotating speed was set to 500 rpm. X-ray analysis indicated that La0.67Ca0.33MnO3 single phase wa…

本研究では、X線回折/リートベルト解析の外部標準法を用い、普通ポルトランドセメント（OPC）および高炉セメント（BB）硬化体中のセメント鉱物やスラグ反応率、水和生成物量を測定した。比較として内部標準法についても同様の測定を行った。その結果、両手法により求めたセメント鉱物やスラグ反応率、水和生成物量の値は概ね一致した。さらに、OPCおよびBBの水和反応と硬化体の微細構造形成との関係について検討し、BBの生成するC-S-Hに内包するゲル空隙は水和後期において増加することで、効率的に毛管空隙が減少することが明らかとなった。
A tunable luminescence from red to blue in Eu-doped mesoporous AlPO4 glass is achieved by adjusting the annealing temperature. With increasing annealing temperature, the increased Eu 3+ ions reduction changes the luminescence of the obtained glass. The abnormal reduction of Eu 3+ to Eu 2+ occurs in AlPO4 mesoporous gl…
