Understanding the structural evolution of covalent systems under rapid cooling is very important to establish a comprehensive solidification theory. Herein, we conducted molecular dynamics simulations to investigate the crystallization of silicon-germanium (SiGe) alloys. It was found that during crystallization, the s…
The isothermal compressibility and pressure dependence of mechanical moduli of PEEK film under extreme conditions have been examined and determined.
The effect of alkali treatment and nanoclay addition on the mechanical properties and water absorption behavior of rice husk particle (RHP) reinforced unsaturated polyester (UP) composites was investigated. Thermogravimetric analysis (TGA) indicated that the alkali treatment removed most of the hemicellulose and impur…
), while in polycrystalline materials scattering at grain boundaries dominates (τ ∼ cte). The Seebeck coefficient, electrical conductivity, and electron heat conduction are in consistent agreement with experiment. Furthermore, the Slack relation for lattice heat conductivity was successfully applied to the material. T…
Omega (ω) phase is formed in alpha (α) zirconium during dynamic loading and can be retained in the recovered material. The pathway for the α to ω change (or the reverse transformation) is not well understood. Zirconium was shock-loaded and the resulting two-phase microstructure was examined. Electron backscatter diffr…
The nature of the surface roughness of electrolessly etched p-type Si nanowires (NWs) is examined using high resolution transmission electron microscopy and shown to comprise individual silicon nanocrystallites throughout the waviness of the roughness features. As the frequency of roughness features are believed to be…
Hexavalent chromium (Cr( <sc>vi</sc> )) is one of the most toxic heavy metal pollutants in groundwater, and thus the detection of Cr( <sc>vi</sc> ) with high sensitivity, accuracy, and simplicity and low cost is of great importance.
of VOCs on MWCNTs and other sorbents revealed that the sorption performance of MWCNTs is much more stable over a wider range of RHs due to better site availability and site quality. Furthermore, for all 6 adsorbents in all RHs, the positive contribution of hydrogen bonding ability was found as compared to the negative…
Porphyrins bearing electron acceptors attached to β-carbon through olefin or phenyl–olefin bridges act as chemodosimeters for CN <sup>−</sup> as well as chemosensors for F <sup>−</sup> , CN <sup>−</sup> and OAc <sup>−</sup> ions depends on acceptor strength and position.
New recycling alternative for multilayer films was successfully presented. Food packaging formed from different materials is difficult to recycle. The use of aluminum, glass, paper, paints, varnishes, and other materials in the rolling processes from plastic packaging is intended to optimize the efficiency of packagin…
Hollow silica–nickel particles were fabricated by coating silica–nickel shell on rape pollen templates following calcination.
Novel strawberry-like Au@CeO <sub>2</sub> nanoparticles, which show higher photocatalytic activity, were fabricated by assembly of block copolymer composite micelles <italic>via</italic> a redox reaction between Au( <sc>iii</sc> ) and Ce( <sc>iii</sc> ).
Chiral low-molecular-weight gelators (LMWGs) derived from amino acids can self-assemble into helical fibers and twisted/coiled nanoribbons by H-bonding and π⁻π interaction. Silica nanotubes with single-handed helices have been prepared using chiral LMWGs through sol⁻gel transcription. Molecular-scale chirality exists…
Production of cellulose nanocrystals (CNCs) from cellulose of oil palm empty fruit bunches (OPEFB) have been done. The delignification of OPEFB was mixed with 17,5% NaOH and carried out in the three-neck flask with refluxed for 2 hour at 80 o C. Further the suspension was bleached with NaOCl 2% for 1 hour at 70 o C. T…
The development of large wind farms is seen as a part of the solution to lowering global carbon emissions through bulk renewable energy generation, and in Europe many wind farms have mainly been constructed offshore where wind and land resources are advantageous compared to onshore sites. Whether onshore or offshore,…
In this paper, cobalt/nickel tungstate materials (CoWO4@NiWO4-A) have been synthetized by co-precipitation in alkaline condition, and the electrochemical behaviors of the samples were investigated. The as-prepared composites have been systematically characterized by powder X-ray diffraction, scanning electron microsco…
This paper presents results from a literature review on use phase of clothing with focus on wool. The aim of the review is to study if there is empirical grounding for assuming that the use phase is different for clothes made of different fibres, and if this information could be used in modelling the use phase. We wil…
The current trend to further reuse water within paper mills has resulted in more accumulated salts, as reflected by increased conductivity values. Although conductivity measurement is widely used in paper mills, its fundamental principles and interpretation are not often fully understood. This keeps papermakers from r…
Proton conducting composite membranes have been prepared via binary mixtures comprising sulfonated polysulfone (SPSU) and natural zeolite (NZ). Polysulfone has been sulfonated in 1, 2-dichloroethane using the homogeneous method with trimethylsilyl chlorosulfonate as sulfonating agent. The ratio of monomer mol and trim…
The aim of present study was to prepare silymarin loaded PLGA polymeric nanoparticles for liver targeting by solvent evaporation method. Special attention was devoted to targeted drug delivery to liver and then the controlled release of drug from the polymeric nanoparticles. PLGA were employed as a bio-degradable poly…
