The effects of Ce-doping on the phase transition of the orbital/spin ordering (OO/SO) are studied through the structural, magnetic, and electrical transport measurements of perovskite vanadate Sm 1− x Ce x VO 3 . The measurements of structure show that the cell volume decreases as x ≤ 0.05, and then increases as Ce-do…
The mechanism of intermetallic compound (IMC) between Copper (Cu) free air ball (FAB) and Aluminum (Al) bond pad has been carefully investigated in this paper. The test vehicle is Pd-coated Cu wirebonds on Al pad in plastic ball grid array (PBGA) package. Palladium (Pd), the anti-oxide material coated on Cu wire will…

摘要： 通过咪唑基离子液单体与二乙烯苯的自由基聚合制备了聚离子液水凝胶，并通过一步还原得到了离子液水凝胶负载金纳米粒子的复合材料。 用UV-Vis光谱和透射电子显微镜研究了金纳米粒子在离子液水凝胶内部的分散状态及阴离子响应性聚集。 结果表明，由于空间位阻和静电作用，制得的金纳米粒子的表面等离子共振吸收峰为527 nm，在离子液水凝胶中呈均匀分散的球形(2~5 nm)；在PF-6阴离子的作用下，形成了疏水性水凝胶，使凝胶收缩，凝胶内部的金纳米粒子发生聚集，其吸收峰红移到532 nm，初步证实了此水凝胶具有阴离子响应性。

This article presents the thermal conductivity and thermal diffusivity of two refrigerants blends undergoing development process. The aim is to investigate and establish these two refrigerant mixtures as atmospheric friendly alternative to R12, which is one of the known ozone depleting refrigerants. The two refrigeran…
The effect of swift heavy ion (SHI) irradiation on the structural and magnetic properties of thin films of Bi-substituted Co2MnO4 prepared by Pulsed Laser Deposition (PLD) is presented. XRD analysis reveals that the BixCo2-x MnO4 (x = 0.0, 0.1 & 0.3) films grown on amorphous quartz, and crystalline LaAlO3 (LAO) exhibi…
Work presented is interested in the characterization of the quasistatic mechanical properties and in fatigue of a composite laminated in jute/epoxy. The natural fibres offer promising prospects thanks to their interesting specific properties, because of their low density, but also with their bio deterioration. Several…
The material sample was prepared by conventional solid state method and sintered in conventional and microwave furnace at different sintering temperatures. Sintered samples were then subjected to XRD and SEM analysis. X-ray diffraction revealed the formation of single phase material. SEM of fractured cross sectional p…

Surface tissue-removal mechanisms, resulting from atmospheric He-H2O2plasma jet fluxes impinging on tissue surfaces, were investigated. We employed primarily optical emission for cataloging relative concentrations of reactive plasma radicals versus plasma-jet conditions. The reactive radicals were then correlated with…
Phenomenological description of below-Tg structural relaxation known as long-term natural physical ageing in network glass formers exemplified by chalcogenide glasses of binary arsenic selenides was adequately developed within formalism of first-order kinetics. This kinetics was shown to obey a character stretched exp…
L-ascorbic acid (AA) and D-isoascorbic acid (IA) are diastereomer each other. Oxidation current responses of AA and IA in aqueous electrolyte solution containing both AA and IA might be successfully observed as two separated anodic peaks from AA and IA, using asymmetric carbon-linked thiol derivative-modified Au elect…
A new method for the preparation of Cu(In,Ga)Se2 absorber layers is developed. The method is based on a single bath electrochemical deposition of Cu-In-Ga oxides in an acidic nitrate based electrolyte. It is cheap, easy to carry out and fast. It takes advantage of the strong affinity of indium and gallium for oxygen.…
Tridentate azomethine ligands (H 2 L) based on 3-allylsalicylaldehyde and o -aminophenol, o -aminothiophenol, or 2-ethylamino-5-nitroaniline were synthesized and identified by IR and 1 H NMR spectroscopies. The structure of complexes ( Ia-Ic ) was studied by magnetochemistry and EXAFS spectroscopy. Complexes Ia and Ib…
The ability of heterometallic Ge(IV) and Sn(IV) complexes [Co(H 2 O) 6 ][Ge(HCitr) 2 ] ( I ), [Co(H 2 O) 6 ] [Sn(HCitr) 2 ] ( II ), [Ni(H 2 O) 6 ][Ge(HCitr) 2 ] ( III ), [Ni(H 2 O) 6 ][Sn(HCitr) 2 ] ( IV ), [Mg(H 2 O) 6 ][Ge(HCitr) 2 ] ( V ), and [Mg(H 2 O) 6 ][Sn(HCitr) 2 ] ( VI ) (H 4 Citr is citric acid) to activat…
This work presents a complete vibrational analysis of iron [ Fe (II) and Fe (III)] and nickel [ Ni (II)] complexes with 5,10,15,20-tetraphenyl-21-oxaporphyrin [OTPPH] and 5,20-bis(p-tolyl)-10,15-diphenyl-21-oxaporphyrin [ODTDPPH]. In these porphyrins, a furan ring replaces one of the pyrrole rings. The six-coordinate…
As the scaling of Si MOSFET approaches towards its limiting value, new alternatives are coming up to overcome these limitations. Carbon nanotube field effect transistor (CNTFET) is found to be one of the most promising alternatives for bulk Si MOSFET. In this work we have simulated a cylindrical CNTFET. Based on the s…
At ab initio level, time-dependent hybrid density functional theory and response theory have been applied to study the solvent effect on the geometrical and elctronic structure as well as one- and two-photon absorption (TPA) properties of 2,2':6',2"-terpyridine-based chromophore L. It is found that solvatochromic shif…
