The present work describes the influence of the friction stir processing (FSP) process parameters, namely the tool rotational speed, the tool traverse speed, and the tool tilt angle on the forming-limit strains, the microstructure and the texture of friction stir processed magnesium AZ31B alloy. Limiting dome height t…
It is shown experimentally that a semitransparent suspension of multiwall carbon nanotubes (MWNTs) in N,N -dimethylformamide (DMF) is irreversibly bleached in a wide optical wavelength range in a field of nanosecond high-power laser radiation with a wavelength of 532 nm. The bleaching is accompanied by a sharp decreas…
Turbulence in Scrape-off layer (SOL) of tokamak plasma has been studied numerically using interchange modes with the help of electron continuity, quasineutrality, and ion energy equations. Electron temperature is assumed uniform. We have studied dynamics of seeded plasma blob and plasma turbulence to identify the role…
An alternating current field (ACF) was employed in pack boriding at 800°C to produce a thick Fe2B coating on an AISI 1045 steel. The effect of ACF on the growth of the boride coating was studied, and the coating's structure and phases were characterised. The results showed that an ACF could greatly enhance pack boridi…
The effect of an aqueous solution of hydrated C 60 -fullerene (HyFn) on the growth and “stationary phase aging” (accumulation of “age-related” changes in cultured cells during the slowing down of their proliferation within a single passage and the subsequent “aging” in the stationary phase of growth) of transformed B1…
Oil palm empty fruit bunch (EFB) is an abundant agricultural waste available in Malaysia. More than two million tonnes (dry weight) of extracted oil palm fiber are estimated to be generated annually. Usually the EFB is used as boiler fuel to produce steam in the palm oil mills. EFB fiber can be used to prepare activat…
Nacareniobsite-(Ce), Na 3 Ca 3 (REE)Nb(Si 2 O 7 ) 2 OF 3 , and britholite-(Ce), (Na,Ca,REE) 10 (Si,P) 6 O 24 (OH,F) 2 , formed during the late stages of crystallization of the most evolved peralkaline granites from the Morro Redondo Complex, Graciosa Province (Southern Brazil). Nacareniobsite-(Ce) compositions are ver…
Bismuth oxide (Bi 2 O 3 ) nanotubes have been successfully synthesised via a rapid microwave‐assisted synthetic method for the first time. A wide range of techniques, such as X‐ray diffraction, field emission scanning electron microscopy, X‐ray photoelectron spectroscopy, UV–vis absorption spectroscopy and photolumine…
Synthesis and solid-state NMR characterization of two isomorphous series of zinc and cobalt coordination networks with 1,2,4-triazolyl benzoate ligands are reported. Both series consist of 3D diamondoid networks with four-fold interpenetration. Solid-state NMR identifies the metal coordination of the ligands, and assi…
The results of testing of Pd(II)-Cu(II)/Bent catalyst samples in the reaction of CO oxidation with air oxygen are presented. Bentonites from three Ukrainian deposits: Gorbskoye, Dashukovskoye, and Kirovogradskoye were used as supports. Natural bentonites, their modified forms, and the catalysts based on them were char…
The fracture behavior of Kevlar/Glass- Epoxy Hybrid Composite was investigated based on experimental and finite element analysis method. The tension test was employed with fixtures as per ASTM standards. Fracture Toughness was determined experimentally for along the fiber direction and across the fiber direction of th…
A facile electrochemical approach has been developed for the template free synthesis of sea-urchins like palladium (Pd) nanoparticles on multi walled carbon nanotubes (fMWCNTs) coated indium tin oxide electrode (ITO). The electrochemical measurements and surface morphology of the as prepared nanocomposite electrode we…
Inspection of Metals: Understanding the Basics covers the tools and techniques used in manufacturing to assess the quality of metal parts or determine if they conform to production requirements or specified standards. The first half of the book discusses common testing and inspection methods, including visual inspecti…
Seeds of common bean (Phaseolus vulgaris) with high molybdenum (Mo) concentration can supply Mo plant demands, but to date no studies have concomitantly evaluated the effects of Mo-enriched seeds on plants inoculated with rhizobia or treated with N fertilizer. This work evaluated the effects of seed Mo on growth and N…
Breast reconstruction is a type of surgery for women who have had a mastectomy, and involves using autologous tissue or prosthetic material to construct a natural-looking breast. Adipose tissue is the major contributor to the volume of the breast, whereas epithelial cells comprise the functional unit of the mammary gl…
The microstructures and dry sliding wear behavior of Al-17Si cast alloys were studied after various melt treatments such as refinement and modification. Results indicate that combined refined and modified Al-17Si cast alloys have microstructures consisting of uniformly distributed primary silicon and fine eutectic AlS…
Power quality is one of the major concerns in the present power system environment. The situations like-voltage dip/sag, swells, harmonic content etc and so on, and its major effect on greatly susceptible loads are well known. To tackle these situations, custom power apparatuses are utilized. Dynamic Voltage Restorer…
With the increasing number of cores in chip multiprocessors, the design of an efficient communication fabric is essential to satisfy the bandwidth and energy requirements of multi-core systems. Scalable Network-on-Chip (NoC) designs are quickly becoming the standard communication framework to replace bus-based network…
Premium (IEC IE3 Class) efficiency Motors are now mandatory in North America. Super-Premium (IEC IE4 Class) and IE5 Ultra-Premium efficiency classes are defined in the second edition of Standard IEC 60034-30. For line-start fixed-speed applications, Super-Premium IE4-Class Line-Start Permanent-Magnet Motors and Squirr…
Crude cellulose as well as alpha- and beta-celluloses were estimated in thirty-four seaweed species of fifteen orders of Chlorophyta, Phaeophyta and Rhodophyta of Indian waters. The greatest yields of crude cellulose and a-cellulose were obtained from Chaetomorpha aerea (approx. 20.0% and 18.5%, respectively), and of…
