Abstract Layered titanium disulfide is used as lithium-ion intercalating electrode material in batteries. The room-temperature stable trigonal 1T polymorphs of the intercalates Li x TiS2(x ≤ 1) are widely-investigated. However, the rombohedral 3R polymorphs, being stable at higher temperatures for large x, are less we…
Magnetron sputtering plasma for the deposition of copper oxide thin film has been investigated using optical emission spectroscopy and Langmuir probe. The intensity of the light emission from atoms and radicals in the plasma were measured using optical emission spectroscopy (OES). Then, Langmuir probe was employed to…
Exposure buildup factors(EBF) for some spin ice compounds such as Dysprosium Titanate (Dy2Ti2O7), Dysprosium Stannate (Dy2Sn2O7), holmium Titanate (Ho2Ti2O7) and holmium Stannate (Ho2Ti2O7) useful in nuclear engineering have been computed for photon energy range 0.015 to 15 MeV upto penetration depth of 40 mean free p…
In this work, a zinc nitride (ZnN) film was deposited at room temperature and subjected to pulse-mode rapid thermal oxidation. The physical and chemical structures of ZnN film were changed during the rapid thermal oxidation process. The presence of zinc-oxygen bonds in the oxidized ZnN film indicated that some nitroge…
Influence of separator material on the high and low frequency series resistance, characteristic time constant, energy and power densities of the supercapacitors (SCs), based on two identical ideally polarizable microporous titanium carbide-derived carbon electrodes in different electrolytes: 1M (C2H5)3CH3NBF4 in aceto…
Protein adsorption on inorganic surfaces involves a complex mechanism which could be controlled by surface functionalization methods. A dry surface functionalization method for powders could be beneficial as compared to wet‐chemical methods, since aspects like suspension preparation and subsequent drying can be avoide…
Crystallinity of oil palm fiber from empty fruit bunch (EFB) with and without tretaments was studied by analyzing the X-ray diffraction (XRD) pattern. In this paper, we focused on the effect of acid hydrolysis onto EFB on the crystallinity of the extracted cellulose. The reaction was carried out by soaking EFB in 1% (…
Composite nanostructures of NaYF4:Yb3+, Er3+@Au have been successfully prepared by attaching gold nanoparticles onto the surface of NaYF4: Yb3+, Er3+ upconversion nanoparticles (UCNPs). NaYF4 inert shell was used to adjust the separation distance between gold nanoparticles and UCNPs. Effects of the gold nanoparticles…
Stress corrosion cracking (SCC) in steel gas pipelines has been experienced in many regions of the world and have been known to cause ruptures. A typical description of a high pH SCC crack is a hoop aligned crack that grows directly into the pipe wall, perpendicular to the direction of applied stress. Many studies hav…
We use large-scale molecular dynamics simulations of the isomerizations of azobenzene molecules diluted inside a simple molecular material to investigate the effect of a modification of the cis isomer shape on the induced diffusion mechanism. To this end we simulate incomplete isomerizations, modifying the amplitude o…
Controlled dispersion of single-walled carbon nanotubes (SWCNTs) in common solvents is a challenging issue, especially for the rising need of low cost flexible transparent conducting films (TCFs). Utilizing conductive polymer as surfactant to facilitate SWCNTs solubility is the most successful pragmatic approach to su…
Three complexes of copper with organosiloxane ligands of bis-azomethine type derived from 1,3-bis(3-aminopropyl)tetramethyldisiloxane and 2-hydroxybenzaldehyde (1), 5-nitro-2-hydroxybenzaldehyde (2), and 3,5-di-tert-butyl-2-hydroxybenzaldehyde (3) having well-established structures were investigated for their ability…
The AANEM strongly recommends that EDX procedures be performed by physicians with comprehensive knowledge of neurological and musculoskeletal disorders to assure accurate interpretation and diagnosis. Individuals without a medical education in neuromuscular disorders and without special training in EDX procedures typi…
The phenomenon of microphase separation is an example of self-assembly in soft matter and has been observed in block copolymers (BCPs) and similar materials (i.e., supramolecular assemblies (SMAs) and homo/block copolymer blends (HBCs)). In this study, we use microphase separation to construct responsive polymer brush…
Abstract In this work Nb-doped TiO2 (TiO2:Nb) films were deposited by reactive sputtering. The substrate was biased with negative pulses to change the energy of the ions nearby the sample surface during the deposition. As consequence, the film crystalline structure and roughness were changed. It was verified that high…
In the present study, four surfactants including AOS, SDS, SDBS, and TX100 were used as the foaming agent and a PHPA polymer with relatively low to high concentrations was added to the solutions prepared in both fresh water and 8 wt. % NaCl. Also, paraffin and vaseline oils with different viscosities were used to inve…
The current review aims to outline the likely medical applications of nanotechnology and the potential of the emerging field of nanomedicine. Nanomedicine can be defined as the investigation area encompassing the design of diagnostics and therapeutics at the nanoscale, including nanobots, nanobiosensors, nanoparticles…
The effects of acetylation of wood flour with vinylacetate and the content of Maleic Anhydride Polypropylene (MAPP) coupling agent before compounding were evaluated relative to water absorption and thickness swelling. Hot water was used to extract materials of sawdust fir flour before acetylation. Fir flour was succes…
Coordination polymer chains have been formed by the direct reaction between HSC6H2Cl2SH and FeCl3·6H2O in the presence of an aqueous solution of the corresponding alkali-metal hydroxide (M = Li, Na, and K) or carbonate (M = Rb and Cs). The structures consist of dimeric [Fe2(SC6H2Cl2S)4](2-) entities bridged by [M2(THF…
We describe a method for the creation of an efficient optical scatter trap by using fully crystalline octahedral Silicon nanoparticles (Si-NPs) of approximately 100 nanometres in size. The light trapping, even when probing an isolated nanoparticle, is revealed by an enormous amplification of the Raman yield of up to 1…
