Poly(lactic acid) (PLA) and kenaf bast fiber (KBF) were melt-blended using brabender into films in the PLA/KBF ratios of 100/0, 90/10, 70/30 and 50/50 for natural soil burial test. This formulation was used to study the biodegradability of PLA and PLA/KBF biocomposites. It was found that the decompositions of the bioc…
The effects of Ag under layer on the micro structural and magnetic properties of the FePt films were investigated. It was found that the thickness of the Ag under layer is very important factor to induce the L10 ordered FePt (001) films with high perpendicular anisotropy. The chemical ordering increased with increasin…
Abstract High-pressure wells are susceptible to gunshock damage when they are perforated with inappropriate gun systems. This paper presents a simulation methodology to predict Tubing Conveyed Perforating (TCP) gunshock loads reliably. This methodology enables completion engineers to evaluate the sensitivity of gunsho…
Abstract A series of new 5,6‐bis(tetradecyloxy)‐2,1,3‐benzoselenadiazole‐based copolymers (PBDT‐DTBSe, PC‐DTBSe, and PF‐DTBSe) have been first synthesized by Stille or Suzuki coupling polymerization reaction. The synthesized copolymers show good solubility in common organic solvents, such as chloroform, tetrahydrofura…
Five filter reactors as tools for higher harmonics suppression in the power system were fabricated with Fe based soft magnetic amorphous ribbons. The fabrication processes that combine amorphous core winding, heat treatment, dipping, drying, cutting, and assembling were performed to obtain low core loss amorphous reac…
Inelastic light scattering has been utilized for examining the structure of glass and its relaxation. However, the quasi-elastic-light-scattering (QLS) phenomenon has not been addressed in much detail. In this study, we observed pronounced QLS-intensity variations in two temperature domains-supercooled liquid (SCL) st…
Using the B3LYP/LANL2DZ method, we have calculated the spatial and electronic structures of a Au32 nanocluster with I h symmetry. The results suggest that the highest occupied orbitals have a significant density of d states, in agreement with angle-resolved photoelectron spectroscopy data for metallic gold. Relying on…
In the current study, high density polyethylene (HDPE)/ ethylene propylene diene monomer (EPDM) blend and organophilic montmorillonite (OMMT) filled HDPE/EPDM was develop aiming at enhancing the thermal properties. Maleic anhydride polyethylene (MAPE) agent and electron beam (EB) irradiation technique were applied as…
The CuI thin films were prepared by a spraying method with acetonitirile as a solvent and CuI as reagents. The parameter investigated in this research is the effect of spraying method either continuously or intermittently sprayed. The influence of spraying method and solution concentration on the surface morphology an…
A new cobalt(II) 4-hydroxobenzoates, [Co2(C7H5O3)2(NO3)2(H2O)4]2H2O was synthesized as binuclear complex and characterized by elemental analyses (CHN), spectroscopic (infrared, electronic, x-ray powder diffraction, scanning electron microscopy SEM,) studies and magnetic susceptibility measurements as well as thermal a…
Abstract Scaling has been a major concern in a conventional gas condensate well production facility in northwest Louisiana. Severe barium sulfate deposits have been noted throughout the facility causing operational issues resulting in increased lifting costs. The production is primarily from two formations, the Cotton…
We find, and analyse, the exact solution of two friendly directed walks, modelling polymers, which interact with a wall via contact interactions. We specifically consider two walks that begin and end together so as to imitate a polygon. We examine a general model in which a separate interaction parameter is assigned t…
The Wang-Landau (WL) Monte Carlo method has been applied to simulate the self-assembly of a lipid bilayer on a 3D lattice. The WL method differs from conventional Monte Carlo methods in that a complete density of states is obtained directly for the system, from which properties, such as the free energy, can be derived…
Thermoplastic natural rubber (TPNR) nanocomposites were prepared by melt blending method with the optimum mixing parameters (140oC, 100 rpm, 12 min) using internal mixer (Haake 600 P). The aim of this work is to study the effects of organo-montmorillonite (OMMT) on the physical and mechanical properties of TPNR with a…
This research is aimed to analysis the effect of holding time, grain size and compacting pressure parameter against compressive strength of Aluminum-5% fly ash using powder metallurgy method. The irregular form and homogeneous particles of aluminum powder used in this research is produced by Merck German, while fly as…
The main aim of this paper is to investigate the crystallinity and hardness properties of Al-Cu/SiCp matrix composite (AMC) materials. The materials were prepared using a noble stir casting technique by varying the percentage of Cu in the Al-Cu matrix. Qualitative X-ray analysis has been carried out to characterize th…
In this article, the effect of service time of centrifugal pan on glass wool has been studied in centrifugal-spinneret-blow (CSB) process. Glass wool was sampled every 24 h and examined by scanning electron microscopy (SEM) and vertical optical microscopy (VOM). The relationship between mean fiber diameter and service…
Little information has been known on the initial – stage oxidation if there is water vapor involved. Cr samples of 10 mm × 10 mm × 1 mm were isothermally oxidized in dry and wet environment respectively for 86.4 ks. Compact and even surface of Cr2O3 was formed on samples oxidized in dry environment. However, the abili…
This article reports on the electrical properties of porous silicon nanostructures (PSiNs) in term of its surface topography. In this study, the PsiNs samples were prepared by using different current density during the electrochemical etching of p-type silicon wafer. PSiNs has been investigated its electrical properti…
SrRuO(3) is a strong itinerant ferromagnet showing many features of 'bad metals' together with Fermi liquid behavior at very low temperature. The intriguing magnetic and transport properties of SrRuO(3) are tightly related to structure, as commonly observed in transition metal oxides. Here we report on the correlation…
