The most important applications of electrospun polymeric nanofibers are by far those from biomedical field. From the biological point of view, almost all the human tissues and organs consist of nanofibroas structures. The examples include the bone, dentine, cartilage, tendons and skin. All these are characterized thro…
Abstract Aiming to identify the complexing mechanisms of heavy metal cations on edge surfaces of 2:1-type clay minerals, systemic first-principles molecular dynamics (FPMD) simulations were conducted and the microscopic structures and complex free energies were obtained. Taking Cd(II) as a model cation, the structures…
BACKGROUND: Despite recent advances in cancer therapy, the treatment of bone tumors remains a major challenge. A possible underlying hypothesis, limitation, and unmet need may be the inability of therapeutics to penetrate into dense bone mineral, which can lead to poor efficacy and high toxicity, due to drug uptake in…
The aim of this research was to fabricate epoxy nanocomposites by utilizing the developed nano filler from oil palm mills agricultural wastes oil palm empty fruit bunch (OPEFB) fibers for advanced applications. Epoxy-based polymer nanocomposites were prepared by dispersing 1, 3, and 5 wt. % nano OPEFB filler by using…
The need for sensitive imaging techniques to detect tumor cells is an important issue in cancer diagnosis and therapy. Surface-enhanced Raman scattering (SERS), realized by chemisorption of compounds suitable for Raman spectroscopy onto gold nanoparticles, is a new method for detecting a tumor. As a proof of concept,…
The structure of Ge20SbxSe80-x (x = 5, 15, 20) glasses was investigated by neutron diffraction, X-ray diffraction, and extended X-ray fine structure measurements at the Ge, Sb, and Se K-edges. For each composition, large-scale structural models were obtained by fitting simultaneously the experimental data sets in the…
The intrinsic carrier transport dynamics in phosphorene is theoretically examined. Utilizing a density functional theory treatment, the low-field mobility and the saturation velocity are characterized for both electrons and holes in the monolayer and bilayer structures. The analysis clearly elucidates the crystal orie…
The photovoltaic market is currently competing for high efficiency cell technologies. Several of these technologies are inherently bifacial. For large commercial systems, the expected annual bifacial gain is significant, from 5 to over 15% [1] . But the lack of standardization [2] and feedback on large systems seems t…
Summary Wetting properties and surface energy characteristics of cross‐linked polyethylene (XLPE) with different nanofillers (such as Al 2 O 3 , SiO 2 , TiO 2 , and clay) were studied using contact angle measurements with water and dimethyl sulfoxide (DMSO) as solvents. Similar trend of variation of contact angle was…
The crystal structures and magnetic properties of the 40 nm brownmillerite SrMnO2.5 film, perovskite SrMnO3-δ film, and mixed-phase film have been systematically investigated. The features of the oxygen vacancy ordering superstructure in the brownmillerite SrMnO2.5 film are observed from HRSTEM as follows: the dark st…
Ionic liquid gating has been shown to metallize initially insulating layers formed from several different oxide materials. Of these vanadium dioxide (VO2) is of especial interest because it itself is metallic at temperatures above its metal-insulator transition. Recent studies have shown that the mechanism of ionic li…
In this combined experimental and theoretical paper, we study the properties of ${\mathrm{Cu}}_{3}\mathrm{Sm}{({\mathrm{SeO}}_{3})}_{2}{\mathrm{O}}_{2}\mathrm{Cl}$ belonging to the francisite family of compounds, which are novel frustrated layered compounds. ${\mathrm{Cu}}_{3}\mathrm{Sm}{({\mathrm{SeO}}_{3})}_{2}{\mat…
We report on synthesis and characterization of a new magnetic nanolaminate (V,Mn)3GaC2, which is the first magnetic MAX phase of a 312 stoichiometry. Atomically resolved energy dispersive X-ray mapping of epitaxial thin films reveals a tendency of alternate chemical ordering between V and Mn, with atomic layers compos…
Well-crystallized boehmite nanoparticles showing different sizes and morphologies were fabricated in an organic additive-free cationic–anionic double hydrolysis method using inorganic aluminum chloride salt and sodium aluminate as dual aluminum sources. By adjusting the molar ratios of Al 3+ /AlO 2 – in the synthesis…
The formation of hydroxyaluminosilicates is integral to the biogeochemical cycles of aluminium and silicon. The unique inorganic chemistry which underlies their formation explains the non-essentiality in biota of both of these elements. However, the first steps in the formation of hydroxyaluminosilicates were hitherto…
Multiblock polymers (MBPs) show great promise as a platform for synthesizing materials with highly customized nanostructures. In these systems, the subtle balance of chain configurational entropy and interactions between dissimilar block chemistries emerge a rich palette of self-assembled structural motifs that may be…
Our recent studies have indicated that direct fluorination can modulate surface electrical properties and suppress surface charge accumulation of epoxy resin insulators. Further, to investigate the resistance to corona discharge of the fluorinated surface layer, the surface fluorinated epoxy sample together the unfluo…
To investigate the characteristics of micro bridges and their interactions with partial discharge (PD) in oil-paper insulation under DC voltage, an experimental platform with two-copper-electrode models is established. Generation and growth of micro bridge impurities are observed. PDs in experimental process are detec…
Epoxy resin is one of the most popular insulation materials used in power equipment, whereas it is easy to crack when used in some large equipment due to its poor toughness. In order to increase the toughness of epoxy resin, adding liquid rubber into epoxy resin is a common way employed in industrial production. Howev…
Epoxy resin is widely used for insulation in cast dry-type transformers, in spite of its weak ability of thermal conduction. One approach to obtain a higher thermal conductivity is to introduce inorganic fillers with high thermal conductivity. The purpose of this paper is to study the effect of high thermal conductivi…
