ZnₓCd₁₋ₓSe QDs sensitized TiO₂ photoelectrodes on FTO substrates have been prepared using an ion-exchange route. The lattice parameters and band gaps of such ZnₓCd₁₋ₓSe QDs were found to have linear and quadratic relationships with the Zn content (x). These TiO₂/ZnₓCd₁₋ₓSe films were further assembled to solar cells a…
ZnO nanostructures were synthesized by sol-gel reaction between zinc oxide and (Octyl gallate), Octyl gallate Evolution was characterized by UV-VIS spectroscopy,), Fourier transform infrared (FT-IR) spectroscopy technique, X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Atomic Force Microscope (AFM). A…
Context: One of the main reasons for the development of resistance to Tuberculosis is the drug-drug interactions as the therapy includes combination of various drugs. One such commonly reported interaction is between Rifampicin and Isoniazid, the two extensively used drugs in the treatment of Tuberculosis in the stoma…
The paper presents measured amplitude-frequency characteristics of dynamic laser interferometer based on Sn2P2S6:Sb photorefractive crystal. It is shown that such an interferometer can be used for optical remote registration of acoustic micro-oscillation in a wide range, while the cutoff frequency of interferometer, w…
A simple route toward the synthesis of mesostructured composite La₀.₇Sr₀.₃Co₀.₂Fe₀.₈O₃x/yGd–CeO₂ (LSCFx/yGDC) (with x and y representing the volumetric% of LSCF and GDC in the composite films) thin films exhibiting both high electrical conductivities and optimized bicontinuous pore-solid network is reported. Because o…
Spectral distribution of photoluminescence (PL) of Li2B4O7:Cu single crystals in unpolarized and polarized light is studied depending on their crystallographic orientation. A complex structure of the main PL peak is detected. The sample orientation is shown to produce no effect on the positions of the spectral maxima…
This work describes the behavior of ASTM A 335 P92 steel under a process of continuous and cyclic oxidation at high temperatures between 450¿ and 700 ¿C in an oxidizing atmosphere. The gravimetric technique was used to observe the isothermal oxidation and the growth rate of oxides which showed a parabolic trend, X2 =K…
Thermoelectric materials have been the topic of intensive research due to their unique dual capability of directly converting heat into electricity or electrical power into cooling or heating. Bismuth telluride (Bi2Te3) is the best-known commercially used thermoelectric material in the bulk form for cooling and power…
油品中有机含硫化物经高温燃烧后产生的硫氧化物，不仅对汽车发动机具有腐蚀作用，而且排入空气中会造成严重的环境问题。首先，制备了疏水性离子液体1-丁基-3-甲基咪唑六氟磷酸盐([Bmim]PF6)和双亲型催化剂[(CH3)3NC16H33]4W10O32，采用红外光谱(FT-IR)，紫外-可见光谱(UV-Vis)和TG-DSC热分析等方法对它们结构进行了相应的表征；研究了H2O2为氧化剂、[(CH3)3NC16H33]4W10O32和[Bmim]PF6构建的离子液体乳液体系催化氧化模拟油中二苯并噻吩(DBT)的反应活性；实验结果表明，随H2O2和催化剂用量的增加、反应温度的升高和反应时间的延长，DBT脱除率单调增加；离子液体乳液脱硫体…

The investigation of the peculiarities of ferroelectric ordering in CuInP2Se6 crystalls by dialectric methods has been carried out. It has been shown that in the vicinity of the phase transition, a dominant contribution to the dielectric response has a cluster nature. The influence of the disorder, inducted by a subst…
In this paper, we analyze the strategies for the development of low-carbon animal husbandry in Taiwan which mainly focuses on strengthening the livestock farm carbon reduction, promoting the livestock breeding energy conservation and emission reduction technology, and develop the environmental protection laws related…
Yb₉Mn₄.₂Sb₉ has been shown to have extremely low thermal conductivity and a high thermoelectric figure of merit attributed to its complex crystal structure and disordered interstitial sites. Motivated by previous work which shows that isoelectronic substitution of Mn by Zn leads to higher mobility by reducing spin dis…
Single crystals of Copper doped Barium Tartarate crystals (CBT) have synthesized by gel technique. Gel acts as a growth medium for the crystals. The crystalline nature of grown crystal was confirmed using powder X-ray diffraction techniques. The functional groups present in the crystals were identified using Fourier T…
Complexes of Ruthenium (VI) of the type [Ru(O)2(L)2] (L = C6H5COO – , C2H5COO – , CF3COO – , CH3COO – ) have been synthesized and characterised using elemental analysis, infrared and Raman spectroscopy.
