Nickel electroplating on low carbon steel are widely used in many industrial application due to its benefit in improving corrosion fatigue life, increasing coating thickness provide good protection against corrosion but in other hand reduce fatigue life in addition to its high cost so applying a relatively thin layer…
The (Pb0.75Ba0.25)(Zr0.70Ti0.30)O3 (PBZT) ceramics were prepared via the combustion technique. (CO(NH2)2) was used as a fuel. The effect of firing temperature on PBZT's phase formation, microstructure and electrical properties were investigated. The calcination and sintering temperatures were 600°C–1000°C and 1100°C–1…
The amount of oxides, their composition and spatial distribution within a particle determine the usefulness and subsequent processing requirements of a powder. The present work summarizes possibilities of qualitative and quantitative analysis of powder surface chemistry by a variety of methods, starting from surface-s…

Materials International Space Station Experiment 6 (MISSE-6) was an experiment designed to examine the consequences of the space environment on various materials used in space-component design. USU’s contribution was comprised of approximately 180 samples that were suspended from the side of the International Space St…

Recently, as the material of turbine discs for the civil airplane, P/M superalloys such as Rene95 and RR1000 have been in practical use. This is because the advantages of P/M superalloys are more pronounced in homogeneous structure, mechanical properties and yield rate than the disadvantage in the cost of the process…
We consider a simple model of carbon nanotubes (CNTs) subject to external electric field E(t). Using a tight-binding approximation for the description of energy bands of CNTs, together with the standard Boltzmann transport equation and constant relaxation time, we predict the effect of self-induced transparency and ab…
Article history It is well established that the active ingredient in a solid dosage form must undergo dissolution before it is available for absorption from the GIT. About 40 % of the newly discovered drugs fall into poorly water soluble or water insoluble categories. The aqueous solubility for poorly water soluble dr…
There is growing interest to study the effect of nanoparticles to break productivity barriers of agricultural and horticultural crops. But variations in the response of plants to nano-particles have been reported in the literature. The effects of nanomaterials on the plant growth and development were dependent upon th…
Here, we present a comprehensive investigation of the dc magnetization and magnetotransport studies on La0.85Sr0.15CoO3 single crystals grown by the optical float zone method. The spin freezing temperature in the ac susceptibility study shifts to lower value at higher dc field and this is well described by the de Alme…
Durante tres anos, se expusieron muestras de alambre de aluminio (usadas para el transporte de electricidad de alto voltaje), en dos diferentes atmosferas, en una marina-costera y la otra rural-urbana, en el clima tropical humedo de la peninsula de Yucatan, en el golfo de Mexico. En estas condiciones de exposicion, la…
The paper presents the results of the research on the long-term corrosion behaviour in service of the reinforced concrete structures located in nitrates-based industrial environments. Two representative types of reinforced concrete structures were investigated: industrial multi-storied buildings of fabrication and gra…
Building raw materials and processed products can vary greatly in radionuclide contents depending on the character and the geology of the their origin. 160 samples of Brick block and 160 samples of Concrete block for constructing dwellings were collected across the Ekiti State, Nigeria. The activity concentrations of…
The microstructure and magnetic properties of Mn–Sn–N and Mn–Sn–Co–N alloys were investigated. All the samples showed low remanences, although high coercivity of 876 kA/m was observed in the Mn–Sn–Co–N alloys. The substitution of Co for Mn increased coercivity. The sample with high coercivity consisted of a fine two-p…
Abstract: This study investigated the influence of the particle size of waste tyre rubber on the rheological properties of Trinidad Lake Asphalt (TLA) and Trinidad Petroleum Bitumen (TPB). Modified TLA and TPB blends containing 0, 1, 2, 3, 4, 5, and 10 wt % waste tyre rubber of particle sizes ranges ≤250 μm,>250 μm to…
In this work a new type of orthogonal self-assembled systems, namely a gelled bicontinuous microemulsion, was investigated with a set of complementary physico-chemical methods. Orthogonal self-assembly means that different structures self-assemble simultaneously in a system and coexist independently. In the chosen mod…
Produksi semen dunia telah menyumbang tujuh persen gas rumah kaca (CO2) atau sekitar 1,5 miliar ton pada tahun 1995 (International World Energy Outlook). Jumlah ini akan terus bertambah seiring berkembangnya industri semen di dunia. Bottom ash merupakan limbah padat yang dihasilkan oleh PLTU. Limbah ini mempunyai komp…
The presence of natural radioactivity in sand and other building materials results in internal and external exposure to the general public. Therefore, it is desirable to determine the concentration of naturally occurring radionuclides. Sand is one of the main components in building construction beside cements, granite…
There are two road condition survey methods commonly used, the roughness-based equipment such as NAASRA and the distress and severity type road evaluation method as presented by ASTM D-6433. The objective of the study is to evaluate the relationship between road condition obtained from roughness type equipment and roa…
