Superconducting layered transition metal dichalcogenides (TMDs) stand out among other superconductors due to the tunable nature of the superconducting transition, coexistence with other collective electronic excitations (charge density waves), and strong intrinsic spin-orbit coupling. Molybdenum disulfide (MoS2) is th…
Energy saving electrochromic windows were achieved by controlling the interfacial charge transfer using low-HOMO level ( <italic>E</italic> <sub>HOMO</sub> < −5 eV) π-conjugated polymers (CPs) as bistable electrochromic films and an ionic liquid as the electrolyte layer. It provided a long bistability (>90 min)…
The interest in the synthesis of Se-containing compounds is growing with the discovery of derivatives exhibiting various biological activities. In this manuscript, we have identified a series of 2,2'-diselenobisbenzamides (DISeBAs) as novel HIV retroviral nucleocapsid protein 7 (NCp7) inhibitors. Because of its pleiot…
Over the past decade magnetoelectric (ME) mutiferroic (MF) materials and their devices are one of the highest priority research topics that has been investigated by the scientific ferroics community to develop the next generation of novel multifunctional materials. These systems show the simultaneous existence of two…
Two-dimensional ferromagnetic monolayer and few-layer CrSiTe <sub>3</sub> crystals are prepared for the first time from the bulk crystals by a simple mechanical exfoliation method.
Synthesis of atom-precise alloy nanoclusters with uniform composition is challenging when the alloying atoms are similar in size (for example, Ag and Au). A galvanic exchange strategy has been devised to produce a compositionally uniform [Ag24Au(SR)18](-) cluster (SR: thiolate) using a pure [Ag25(SR)18](-) cluster as…
In this work, we demonstrate the use of high performance nanostructured PbTe-based materials in high conversion efficiency thermoelectric modules.
Manufacturing of aerogels and membranes from hexagonal boron nitride (h-BN) is much more difficult than from graphene or graphene oxides because of the poor dispersibility of h-BN in water, which limits its exfoliation and preparation of colloidal solutions. Here, a simple, one-step mechano-chemical process to exfolia…
The advances in the preparation of N-doped carbons and their applications in supercapacitors are reviewed.
Thermoelectric technology, harvesting electric power directly from heat, is a promising environmentally friendly means of energy savings and power generation. The thermoelectric efficiency is determined by the device dimensionless figure of merit ZT(dev), and optimizing this efficiency requires maximizing ZT values ov…
Tanaman resam (latinnya dicranopteris linearis ) merupakan pakis hutan yang hidup di perkebunan karet dan tumbuh hampir diseluruh provinsi di Indonesia. Tumbuhan ini menjalar dan memiliki panjang kurang lebih 7 meter. Penelitian terhadap pemanfaatan serat resam sebagai bahan komposit sudah dilakukan oleh penulis sampa…
The photodegradation of poly(fluorostyrene) isomers with different amounts of phthalate and terephthalate plasticizers has been investigated with the aid of Fourier‐transform infrared spectroscopy. Photo irradiation was carried out with light from a Hydrogen‐Xenon lamp at 265 nm and 293 K. As irradiation time increase…
This study displays the influence of TiO2 nanocontainers loaded with corrosion inhibitor 2-mercaptobenzothiazole into hybrid organic-inorganic coatings on the active corrosion protection of modified 9Cr-1Mo ferritic steels. The corrosion resistance and the self-healing effects of this hybrid passive barrier coating wi…
Samples of microcrystalline cellulose (MCC) have been studied by X-ray photoelectron spectroscopy before and after sulfation. It has been found that the reaction of MCC with chlorosulfonic acid in dioxane results in the incorporation of sulfate groups into the structure of cellulose. The content of sulfur in sulfated…
The use of biomolecules as oxidants for the synthesis of conducting polymers provides an important tool for the control of polymer properties. Using PEDOT: PSS as a representative conducting polymer, we compare a set of heme proteins (soybean peroxidase, cytochrome c, and horseradish peroxidase) used as oxidants. The…
In our experiment, it was observed that silicon nanocrystal rapidly grows with irradiation of electron beam on amorphous silicon film prepared by pulsed laser deposition, and shape of silicon nanocrystal is usually sphere in smaller nanoscale with less exposure time under electron beam, in which the quantum dots are p…
The influence of the composition of solutions of peracetic acid on a change in the characteristics of cellulose during the oxidative-hydrolytic destruction of aspen and pine wood under microwave radiation was investigated. Samples of the prepared cellulose were characterized by viscometry, X-ray diffraction and IR spe…
Effects of aging on martensitic transformation temperature, microstructure and shape memory characteristics were investigated for Ti50Ni20Pd30 and Ti52Ni18Pd30 alloys. There was no significant change in the microstructure and transformation temperature by aging, irrespective of aging temperature, in case of the Ti50Ni…
Abstract The paper discusses the methods of modification of melt-blown polymer materials by the addition of a bactericidal agent or superabsorbent directly to the fibre-forming area during the melt-blown production process. It also presents tests of textile composites designed for use in selected types of personal pro…
Reaction‐bonded B 4 C ( RBBC ) was fabricated through molten Si infiltrating porous B 4 C preforms. A preform with a 75% relative green density was obtained by mixing two different sized B 4 C powders. Carbon black added to the preform slightly reduces average pore size, but increases porosity. RBBC ceramics showed a…
