Geographic associations of duplex soils, like the Estcourt form, and plinthic soils, like the Avalon and Westleigh forms, such as are found in the Eastern Free State, are recognised worldwide. These soils share redox morphology. In duplex soils, the redox morphology is dominated by a contrast in clay content between t…
The water treeing phenomenon has been recognized as an ultimate difficulty for long-term service life of cross-linked polyethylene (XLPE) insulated power cables. Elucidation of substantial mechanistic pathway of water treeing is quite important to suppress water treeing. Many factors which affect water treeing have be…
In the design and construction of waterfront structures, there is a need for development of a corrosion resistant, lightweight, cost effective and environmentally friendly structural material. Hybrid wood-plastic composite (WPC) - fiber-reinforced polymer (FRP) structural members would be corrosion resistant, and rela…
Corrosion prevention methods of materials are key technologies to increase in power generation efficiency, reduce in environmental pollution and realize maintenance-free in the waste-to-energy plants. Corrosion environment have became severe condition according to social demands such as increase in calolific value of…
Development of micro seismic generator for energy harvesting applications is presented. In order to fabricate MEMS-friendly high-performance electret film, CYTOP is adopted as an electret material and the charge density and the charge stability of CYTOP is experimentally characterized. When corona charging is employed…
Functional, conjugated molecular structures have been fabricated on Au nanoparticles via the Sonogashira coupling reactions.
A technique to prepare one-dimensional anisotropic photonic crystals and microcavities based on anisotropic porous silicon exhibiting optical birefringence has been developed. Reflectance spectra demonstrate the existence of a photonic band gap and of an allowed microcavity mode at the photonic band gap center. The sp…
The growth direction of solid phase, which has a great influence on the grain selection, has been investigated. Transparent organic systems, succinonitrile–H2O alloy and pivalic acid–H2O alloy have been used for unidirectional solidification. Essential parameters of phase diagrams, distribution coefficient of H2O (k)…
Abstract The technique of fluid dynamic gauging has been successfully applied to assess the adhesion characteristics of thin (< 1 mm) layers of calcium sulphate deposits serving as mimics of mineral scales often found on heat transfer surfaces. The shear strength of the scale layers increased on ageing; layers aged…
It is necessary to acquire the mechanical properties of advanced plain-weave fabrics as design parameters for application to ultra-light structures. In this study, biaxial tensile experiments of cruciform specimens with an open hole were conducted to evaluate the strength of coated plain-weave fabrics composed of spec…
A negative working photosensitive polyimide (PSPI) for use as a semiconductor surface coating material has been developed. This material has been widely used as a buffer coating to protect electrical circuitry on IC chips in the semiconductor market. We have now developed a new negative working photosensitive polynorb…
In Ag electroless plating, Ag agglomeration has been the obstacle to obtain thin Ag films. The crystallographic misfit between the substrate and Ag can accelerate Ag agglomeration. In this paper, Au, whose crystallographic characteristics are similar with those of Ag, is used as the activation material. As a result, t…
The polymerization and pore sealing that occurs during fluorocarbon plasma treatment of nanoporous silica xerogel was investigated experimentally by Rutherford backscattering spectroscopy and successfully modeled using a diffusion-reaction analysis. was used as a reactant gas to expedite the rate of polymerization due…
This study was carried out to investigate the effects of precipitation of σ phase and N addition and the change of volume fraction on the mechanical properties in 25Cr–7Ni–4Mo–2W super duplex stainless steel. The results obtained from this study are as follows: With increasing the annealing temperature, the volume fra…
The production of leather from animal hides or skins is accomplished through the use of tanning agents that stabilize the collagen matrix. The molecular characteristics of tanning agents are quite varied, and led to the expectation that leathers produced with different tanning agents would have fundamentally different…
In order to meet future emissions regulations, new combustion concepts are being developed. Among them, the development of low-temperature diesel combustion systems has received considerable attention. Low NOx emissions are achieved through minimization of peak temperatures occurring during the combustion process. Con…
Aluminum alloy is one of the most important materials in aviation industry.Its development his- tory is closely connected with that of aircrafts.The application and development of advanced aluminum alloys in air- craft industry are briefly described in this paper.The gap of aluminum alloy application in aviation indus…
Thin-film thermoelectric materials offer great potential for improving the thermoelectric figure of merit ZT due to the freedom of tailoring the electron and heat transport. The characterization of these thin films is difficult because of the coexistence of the substrate, non-ideal contact, and asymmetric three-dimens…
The critical thickness for ferroelectricity has assumed importance because of the integration of ferroelectric perovskite films into microelectronic devices. Recent calculations reported by Junquera and Ghosez (J. Junquera and Ph. Ghosez, Nature, 2003, 422, 506, ref. ) have shown the critical thickness in the case of…
This study seeks to clarify the effects of gas contamination from milling atmospheres of mechanical alloying (MA) on mechanical properties. An iron-based dispersion alloy of Fe-13Cr-3W-0.5Ti-0.5Y2O3 (mass%) was selected as the experiment material. We prepared MA powders by milling mixed powders in atmospheres of argon…
