The binding energies, geometric structures and electronic properties of molybdenum trioxide (MoO3) molecule encapsulated inside (8,0), (9,0), (10,0) and (14,0) single-walled carbon nanotubes (SWNTs) have been investigated using density functional theory (DFT) method. Due to curvature effect, the calculated binding ene…
Ceramics are a class of materials widely used during last fifteen years for orthopaedic applications. It is well known that they are characterized by low wear rate, and friction coefficient. However, these materials are very difficult to machine into complex shapes because of their brittleness and high hardness. The m…
β-SiC-particle-dispersed-aluminum (Al) matrix composite was fabricated in the solid-liquid co-existent state by the Spark Plasma Sintering (SPS) process from the mixture of β-SiC powders, Al powders and Al-5 mass% Si powders. The microstructures and thermal conductivities of the composites fabricated were examined. Th…
Mesoscale power generation operated on liquid fuels has the potential for delivering higher energy density (per unit volume) or specific energy (per unit mass) than battery technology. In this study, a complete mesoscale power generation system that incorporates a novel thermoelectric module to generate electrical pow…
Thixotropic, shear-thinning epoxy adhesives are the optimum choice for in situ assembly of timber structural joints under ambient conditions. These adhesives are suitable for injection into roof members and under bridge decks where gravity is a problem for conventional adhesives. However these ambient cure adhesives p…
A few additional things need to be done before actually starting work on the land. This includes a review of any regulatory requirements that, if ignored, could result in costly delays and penalties. You also need to develop a phasing plan for the work, then reconsider and refine your budget with estimates for each ph…
Quadrupole mass spectrometry (QMS) has been applied to monitor the etching processes in a localized plasma etching system. An inward plasma was employed for etching in which the etching gas was discharged in the narrow gap between the etched sample and the entrance of an evacuating capillary tube. As the etching produ…
硬化セメントペーストを構成する水和生成物であるC-S-H（ケイ酸カルシウム水和物）、エトリンガイト、モノサルフェート水和物ならびに水酸化カルシウムの4種類を単独で合成し、それぞれをCr（VI）、As、Se、B、F及びAlの微量元素を含む溶液中に分散・振とうさせ、振とう後の溶液中の各元素の残存量より、セメント水和生成物による固定化率を求めた。その結果、微量成分毎に、セメント水和生成物への固定化率が異なる特徴があることが分かった。C-S-Hは、Alを固定化しやすく、エトリンガイトはSe、F、モノサルフェート水和物はCr（VI）、Se、B、F、水酸化カルシウムはAs、Se、F、Alの固定能に優れていた。
The present paper reports the feasibility and study of one dimension porous silicon (PS) based photonic bandgap (PBG) microcavity structure for an optical sensing of ethanol. 1D-PSPBG microcavity was fabricated by electrochemical etching process. The reflectance measurement of the 1D-PSPBG microcavity was performed fo…
Nanotechnology is blossoming into one of the premiere technologies of this century, but the key to its progress lies in developing more efficient nanosynthesis methods. Variations in synthetic technique, however, can cause variations in size, structure, and surface characteristics, thereby altering the physical proper…
We report on a cost-effective alternative synthetic method for creation of ZnO-based natural-dye sensitized solar cells (DSSC). ZnO arrays were electrodeposited on transparent fluorine doped tin oxide covered glass cathodes in aqueous electrolytes in three-electrode cell under potentiostatic conditions and under pulse…
The crystallization behavior of ZnO-Al2O3-SiO2-ZrO2 glasses was investigated by DTA and XRD in order to prepare transparent glass ceramics containing ZnAl2O4 nano-crystal. The crystallization peak temperature (TC) obtained by DTA was used as a measure of the number of nuclei formed in the glass sample during heat trea…
A selected thermoplastic polyphosphazene elastomer containing two substituents: trifluoroethoxy group and allylphenoxy group had been both heat and radiation treated in presence of nano-silica and nano sized titanium dioxide (TiO2). Characterization of the heat treated materials were performed by Fourier Transform Inf…
The possibilities to prepare high quality substrates for second generation high temperature superconductors based on Ni—W alloys in the 0-9.5 at. % W concentration range was studied. Researches and developments were carried out in the following directions: a) Ni—W alloy synthesis; b) preparation of Ni—W alloy tapes by…
Fundamentals of titanium as an effective actor in deoxidation and inclusion forming additive in steel are discussed. Ti-O equilibria in pure iron and in different example steels are compared and the premises for the influence of titanium are shown. Formation and transformations of titanium containing inclusions during…
(50-x)CaO-xPbO-50P2O5 glasses (0 ≤ x ≤ 50) were synthesized by quenching technique. They have been characterised by Fourier transform infrared (FT-IR) and Raman spectroscopies. FT-IR and Raman spectral investigations reveal the formation of P-O-Pb bonds which replace P-O-Ca bonds and show that no metaphosphate network…
In any industry, the three top operating expenses are often found to be energy (both electrical and thermal), labour and materials. If one were to relate to the manageability of the cost or potential cost savings in each of the above components, energy would invariably emerge as a top ranker, and thus energy managemen…
