A new method for manufacturing Mn18Cr18N steel applied to retaining ring has been developed based on hollow ESR ingot. The ESR hollow ingot not only keep away from upsetting and punching, provide hollow billet for forging directly, but also meet the need of high quality of the raw material. ESR hollow ingot of Mn18Cr1…
Low donor content solar cells containing polymeric and non-polymeric donors blended with fullerenes have been reported to give rise to efficient devices. In this letter, we report that a dendrimeric donor can also be used in solution-processed low donor content devices when blended with a fullerene. A third generation…
A mechanically durable and air stable organic rectifier diode is demonstrated, taking advantage of face-on grown copper phthalocyanine and a polyethylenimine ethoxylated/Au cathode. The current density reaches 20 A cm−2 at 2 V with a rectification ratio of 6.5 × 107 and the diode is mechanically robust, even against f…
BACKGROUND: According to structure-dependent function of proteins, two main challenging problems called Protein Structure Prediction (PSP) and Inverse Protein Folding (IPF) are investigated. In spite of IPF essential applications, it has not been investigated as much as PSP problem. In fact, the ultimate goal of IPF p…
Cellulose is one of the most abundant biological polymers on Earth, and is synthesized by the cellulose synthase complex in cell membranes. Although many cellulose synthase genes have been identified over the past 25 years, functional studies of cellulose synthase using recombinant proteins have rarely been conducted.…
Обобщены результаты исследования поведения неметаллических включений и трансформации межфазных границ включение—матрица при высокоэнергетических обработках сталей (горячая деформация, лазерная обработка, высокотемпературный отжиг). Изучены закономерности проскальзывания вдоль границ включение—матрица при различных реж…
Abstract A receptor containing amidopyrrole binding subunits and free amino groups, conjugated to a naphthalimide dye, has been designed and synthesized. The intrinsic selectivity of the binding motif for phosphate present in DMSO completely disappears in 10 % DMSO aqueous buffer at pH 3.6, at which the receptor is pr…
Ten peroxide compounds based upon the 3,6‐di(hydroperoxy)‐1,2‐dioxane, 2‐hydroxy‐6‐hydroperoxy‐1,2‐dioxane, 3,5‐di(hydroperoxy)‐1,2‐dioxolane, and 3‐hydroxy‐5‐hydroperoxy‐1,2‐dioxolane skeletons have been synthesized, structurally characterized, and fully evaluated for their energetic materials properties. The solid‐s…
We present the mechanism for breaking the symmetry in sound transmission between any two neighboring ports in a passive multi-port system. Numerical simulations and experimental measurements verify that by using judiciously designed metastructures to provide an extra wavevector without blocking the sound path, the pro…
To simultaneously improve both open-circuit voltage ( V oc ) and short-circuit current density ( J sc ) for organic solar cells, a novel D(A-π-Ar) 3 type of photovoltaic small molecules of TPA(F x BT-T-3Cz) 3 was designed and synthesized, which contain central triphenylamine (TPA), terminal carbazole (Cz), armed fluor…
Cavity resonant modes of shielding enclosure for housing electronic circuits may cause electromagnetic interference (EMI). Here, we present an effective approach by using graphene to suppress unwanted resonant modes while maintaining good transparency to visible light. The structure consists of graphene sheet on quart…
Anomalous temperature dependent magneto-electroluminescence was observed at low and high magnetic field strength from organic planar heterojunction devices incorporated common phosphorescent host materials of N,N′-dicarbazolyl-3,5-benzene (mCP) or 4,4′-N,N′-dicarbazole-biphenyl (CBP) as an emissive layer. We found tha…
In the Regulation 1223/2009, evaluation of packaging has become mandatory to assure cosmetic product safety. In fact, the safety assessment of a cosmetic product can be successfully carried out only if the hazard deriving from the use of the designed packaging for the specific product is correctly evaluated. Despite t…
Abstract High‐speed video data for four hybrid lightning flashes show luminosity bursts at visible wavelengths that are time‐correlated with large, intracloud flash (IC) initial breakdown (IB) pulses in electric field change (E‐change) data. The candidate IC‐type IB pulses are large in range‐normalized E‐change amplit…
The superior biomechanical properties of bone and dentin are dictated, in part, by the unique plate-like morphology of hydroxyapatite (HAP) nanocrysals within a hierarchically assembled collagen matrix. Understanding the mechanism of crystal growth and thus morphology is important to the rational design of bioinspired…
Dipole-coupled cobalt nanomagnet pairs of elliptical shape (with their major axes parallel) are delineated on 128° Y-cut lithium niobate. Each pair is initially magnetized along the major axis with a magnetic field forming the (↑↑) state. When an acoustic wave (AW) is launched in the substrate from interdigitated elec…
A platinum-free counter electrode composed of surface modified aligned multiwalled carbon nanotubes (MWCNTs) fibers was fabricated for efficient flexible dye-sensitized solar cells (DSSCs). Surface modification of MWCNTs fibers with simple one step hydrothermal deposition of cobalt selenide nanoparticles, confirmed by…
Purpose This study aims to construct a double layer heat insulation coating based on hollow glass microspheres (HGMs) and to investigate the effect of particle size on barrier property and heat insulation performance. Design/methodology/approach The waterborne double layer coating was composed of an anticorrosive epox…
An overview of quantum‐mechanical methods to generate cross‐section data for electron collisions with atoms and molecules is presented. Particular emphasis is placed on the time‐independent close‐coupling approach, since it is particularly suitable for low‐energy collisions and also allows for systematic improvements…
In eukaryotic DNA replication initiation, hexameric MCM (mini-chromosome maintenance) unwinds the template double-stranded DNA to form the replication fork. MCM is activated by two proteins, Cdc45 and GINS, which constitute the 'CMG' unwindosome complex together with the MCM core. The archaeal DNA replication system i…
