We report here the first experimental results on the laser Raman spectroscopic, powder X-ray diffraction (XRD) and X-ray photoemission spectroscopic and high-temperature differential thermal analysis studies on graphite from the Burugubanda-Tapasikonda shear zone in the Proterozoic Eastern Ghats Mobile Belt (EGB) of A…

有机性地作为中间的、中国冷杉木(Cunninghamia lanceolata ) 作为 organophilic 与 montmorillonite (MMT ) 修改了 MMT (OMMT ) 和水溶性的酚甲醛树脂(PF ) wood/MMT nanocomposites (WMNC ) 经由加重的 nano 置闰被准备并且由 XRD， SEM 和 FTIR 描绘了。结果显示出那：1 ) OMMT 的准备是很成功的；2 ) 白手起家的 PF 能有效地设置进 MMT markably 增加它的画廊距离甚至剥落它的 nano 硅酸盐薄片；3 ) XRD 分析显示一些 exfoliated MMT 在 WMNC 减少在木头房间墙和木…
The NiII complexes of cyclen- and cyclam-pyridine (respectively 1-pyridin-2-ylmethyl-1,4,7,10-tetraazacyclododecane and 1-pyridin-2-ylmethyl-1,4,8,11-tetraazacyclotetradecane denoted [NiIIL1]2+ and [NiIIL2]2+) have been isolated and characterised by X-ray diffraction, UV-visible spectroscopy and electrochemical studie…
This paper describes the influence of severe plastic deformation (SPD) on the structure, phase transformations, and physical properties of melt-spun Ti2NiCu-based and Ni2MnGa-based shape memory intermetallic alloys. It was found that the SPD by high pressure torsion (HPT) at room temperature can be effectively used fo…
In this paper, the transmission line theory is utilized to characterize the metamaterials comprising of microscopic elements of a periodic array, specifically, the traditional split-ring resonators (SRRs), as an example. The bianisotropic property of the metamaterials is characterized in a new way different from the e…
A novel addition-type liquid silicone rubber (AL-SR) adhesive has been prepared by incorporation of organic montmorillonite (OMMT). Physico-mechanical properties, such as adhesion, tensile strength and thermal stability, were investigated and compared to aerosilica (also known as pyrogenic silica) filled systems. Resu…
In the heat-transfer analysis of a solidification process, the effective specific heat method is conceptually simple to apply while dealing with the latent heat problem. The implementation of computer program is very easy for this method. However, in a time step, if a nodal temperature enters, leaves or jumps over the…
A review is given of the strategies used to dope inorganic solids and the consequences for properties such as ionic and electronic conductivity. Doping mechanisms involve either substitution of foreign ions onto lattice sites, creation of vacancies on either cation or anion sites, or population of normally empty inter…
The energy storage potentials of many different carbon nanotube (CNT) materials are investigated electrochemically. The electrochemical response of all the investigated materials is rather featureless during charging and discharging and does not show any phase transitions or clear redox responses. The maximum discharg…
Mixed Ionic–Electronic YSZ/Ni Composite for SOFC Anodes with High Electrical Conductivity, Fonseca, Fabio C., de Florio, Daniel Z., Esposito, Vincenzo, Traversa, Enrico, Muccillo, Eliana N.S., Muccillo, Reginaldo
The sintering behavior of 7.8 mol% Yttria-stabilized cubic stabilized zirconia (Y-CSZ) powders was investigated, with emphasis on the effect of Al2O3 addition at the initial sintering stage. The shrinkage of powder compact was measured under constant rates of heating (CRH). The powder compact with 0.25 mass% Al2O3 enh…
Wormhole-like mesostructured alkali-free borosilicate glasses (MBSGs) with different compositions have been synthesized by a combination of surfactant templating, sol–gel methods and evaporation-induced self-assembly (EISA) processes.
The process of severe plastic deformation (SPD) was applied to Al alloys in order to demonstrate that it is possible to control the morphology and distribution of second phase particles using SPD. Equal-channel angular pressing (ECAP) is used for the SPD process and transmission electron microscopy is used for the mic…
The main contribution of this paper is to show the realizability of epoxy-based nanocomposites as industrial insulating materials. The nano- and micro-filler mixture was invented to boost the nanocomposite in industrial insulating materials. Nano- and micro-filler mixture composites were newly made by dispersing a few…
The commonly used die-cast magnesium alloy AZ91D in chip form bearing different environmental corrosive conditions was compacted, and then extruded in order to assess the feasibility of recycling in solid-state. This recycled material showed no inferior mechanical properties than its un-chipped counterpart. It was als…
Increasing resistivity of copper with scaling and rising demands on current density requirements are driving the need to identify new wiring solutions for deep nanometer scale VLSI technologies. Metallic carbon nanotubes (CNTs) are promising candidates that can potentially address the challenges faced by copper and th…
This work is centered on the study of the corrosion inhibition of copper in 1 M HNO3 by N-phenyl oxalic dihydrazide (PODH) and oxalic N-phenylhydrazide N-phenylthiosemicarbazide (OPHPT) synthesized in our laboratory. The inhibition efficiency obtained by chemical (weight loss) and electrochemical (potentiodynamic pol…
Amide derivatives of L-alanine and ε-caprolactam were readily obtained on diamine-functionalized oxidized single-walled and pristine multi-walled carbon nanotubes through a one-step direct amidation reaction, which employs thermal activation at 160–200 °C instead of chemical activation, avoids the use of organic solve…
The stress that acts on the core by installing a stator in a frame influences the performance of a motor. To reflect this influence in the equipment design, the stress dependence of the magnetic property was examined for non-oriented electrical steels, which are the core materials. This time, the stress dependence of…
