A tetraphenylethylene core-based small molecular acceptor with a unique 3D molecular structure is developed. Bulk-heterojunction blend films with a small feature size (≈20 nm) are obtained, which lead to non-fullerene organic solar cells (OSCs) with 5.5% power conversion efficiency. The work provides a new molecular d…

Abstract A fullerene ammonium derivative has been combined with different metalloporphyrin–crown ether receptors to generate very stable supramolecules. The combination of fullerene–porphyrin and ammonium–crown ether interactions leads to a strong chelate effect as evidenced by a high effective molarity (3.16 M). The…
Abstract The surface structure and catalytic properties of Pt–Ru bimetallic catalysts with identical bulk composition can be continuously tuned by treatment at different temperatures. The activity of these catalysts in CO oxidation was positively related to the treatment temperature, but the opposite trend was observe…
Mutual solubilities in crystalline phases in the system SiO 2 –GeO 2 have been investigated up to 10 GPa pressure and 1500°C temperature, using a bulk composition of 50 mol% GeO 2 . Solid solution of up to 40 mol% GeO 2 into the mineral quartz has been confirmed as well as solubility of Si into GeO 2 rutile (argutite)…
A simple, cost effective and time consuming approach for biosynthesis of monodispersive silver nanoparticles (AgNPs) by Excoecaria agallocha leaf extract and its free radical scavenging activity is described. Different concentration of E. agallocha leaf broth solution (EALB) is used as a process variable to optimize n…
Nanogold particles (NG) were modified by anti-rabbit antibody (RAb) against human chorionic gonadotropin to obtain an immunonanogold probe (ING). In pH 7.0 Na2HPO4-citrate buffer solution containing KCl, ING probes formed large aggregates in which Victoria blue B (VBB) molecules were adsorbed on the surface and which…
The unoccupied electronic structure of tetrakis(phenyl)- and tetrakis(pentafluorophenyl)-porphyrin thick films deposited on SiO2/Si(100) native oxide surfaces has been thoroughly studied by combining the outcomes of near-edge X-ray absorption fine structure spectroscopy at the C, N, and F K-edges with those of scalar…
The drying process of clear precursor solutions for fabricating highly porous titania films was observed by CLSM. Further, we succeeded in detecting the formation of micelles in the precursor solution containing high-molecular-weight PS-b-PEO diblock copolymers at the initial stage of the drying process as the direct…
The Ti–6Al–4V alloy is used for biomedical implants due to its corrosion resistance and biocompatibility, associated with the spontaneous formation of TiO2 oxide. However, the native film may be flawed and after some time of implantation in the body it may release metal ions. Oxides of higher thickness than naturally…
The wild Antheraea pernyi silkworm cocoon is a thin and light-weight structure, yet it has shown effective thermal insulation characteristics against extreme temperature fluctuations, which meet the demands of humans for lighter materials with higher thermal resistance. We present a two-dimensional computational fluid…
H NMR spectroscopy reveals hydrolytic instability of the product under ambient conditions; however, the polymers are sufficiently stable in dry ethanol for at least 14 days. The combination of this hydrophilic polymer with acrylate and phosphonic acid groups constitutes a versatile platform technology for the preparat…
Cotton stalk based activated carbon (AC) was prepared from Xinjiang, China by H3PO4 as activating reagent. In order to improve electrochemical properties of AC, a series of AC/MnO2 (electrolytic manganese dioxide)/AC composites with different MnO2 contents were prepared. The samples specific surface area and pore dist…
Hydroxyapatite (HAP) coatings are being widely used on implant materials in order to improve the bioactivity, however, failure at the implant/coating interface is still a major concern. Functionally graded metal matrix composite structures, on the other hand, are being considered as an alternative to the coatings. The…
The systematic and comprehensive evaluation of corrosion experiments in geothermal waters in Central Europe shows that the pitting resistance equivalent number (PREN) provides information on the potential chemical resistance of materials. The analysis exhibits that tested stainless steels (PREN ≥ 45), nickel‐based all…
Electrical percolation in nanocomposites consisting of poly(methyl methacrylate) (PMMA) and antimony tin oxide (ATO) nanoparticles was investigated experimentally using monosize and polydisperse polymer particles. The nanocomposites were fabricated by compression molding at 170 °C. The matrix PMMA was transformed into…
Structural relaxation in binary hard spherical particles has been shown recently to exhibit a wealth of remarkable features when size disparity or mixture composition is varied. In this paper, we test whether or not similar dynamical phenomena occur in glassy systems composed of binary hard ellipses. We demonstrate vi…
The adsorption and co-adsorption of CO and H2 at different coverage on the CdI2-antitype metallic Mo2C(001) surface termination have been systematically computed at the level of periodic density functional theory. Only molecular CO adsorption is possible and the monolayer coverage (1 ML) can have 16CO adsorbed at the…
Abstract Polyimides are a sophisticated family of materials, which cover an exhaustive range of high performance polymers and find applications from aerospace to microelectronics. Microelectronic applications demand low dielectric constant and high performance. Aromatic terpolyimides were synthesized by reacting 3,3′,…
Background : To satisfy the customers’ emotional as well as material desires, industrial design requires collaborative activities with other areas of profession such as engineering, marketing and so on. The focus of this study is to investigate possible conditions to minimize the conflicting impacts so as to allow mor…
