Core Ideas A flow system for the release and extraction kinetics of ions from a rock fertilizer. The initial release of ions from syenite studied using ICP‐MS and a pH meter. Fast surface potassium–proton ion exchange and K desorption observed. Syenite is mainly composed of potassium feldspar (Kfs), which is a structu…
In this study, the rheological behavior of geopolymeric inorganic binder was determined. This binder was synthesized by alkaline activation of mixture, comprising calcined claystone powder and milled blast furnace slag. As an alkaline activator of hardening process, the potassium silicate solution was used. For the in…
In this study, we report a two-dimensional (2D) hexagonal disk obtained by carbonization of Botryococcus braunii (B. braunii) residues. Carbonization at 700℃followed by naturally cooling down to room temperature under a non-inert gas flow atmosphere affords to yield this unique structure. The 2D hexagonal disks consis…
Cerium substituted FeBO3 samples were investigated according to their crystal and electronic properties via the general formula CexCuFe1-x BO3. With the doping of the heavy fermion “Cerium”, samples were determined in polycrystalline structure. With the incressing Ce in the samples, disturbances on the Cu-Fe planes be…
The results of the simulation of the glass transition process of argon at cooling rates of 1012, 1013, 1014, and 1015 K/s are reported. At temperatures far below the melting point, T f = 83.8 K, the second maximum of the radial distribution function is split into two peaks, which is connected with the glass transition…
By example of samples of railway transport parts of cast and wrought steels, a need for surface preparation for X-ray measurements of surface stress providing removal of a cold-hardened surface layer 150–200 μm thick is shown. Basic principles and criteria of the required quality of surface preparation are determined.
Correction for ‘Charge transport mechanisms in sol–gel grown La 0.7 Pb 0.3 MnO 3 /LaAlO 3 manganite films’ by Eesh Vaghela et al. , Phys. Chem. Chem. Phys. , 2017, DOI: 10.1039/c6cp07730g.
Lead-bismuth eutectic (LBE) loop test is highly contributes to the lead-alloy-cooled fast breeder reactor (LFR) and accelerator driven system (ADS) research and development by providing comprehensive results of both corrosion and erosion phenomenon. Bellows-sealed valve is a crucial part in the LBE loop test apparatus…
Важным звеном технологии ремонта лопаток турбины ГТД является удаление отработанных покрытий с поверхности лопатки сложного профиля. Разработан способ удаления жаростойких конденсационно-диффузионных покрытий в электролитной плазме направленной струей электролита, который позволяет осуществлять равномерное послойное у…
The temperature dependence of current–voltage (I-V) characteristics of Au–Ge/p-GaSe:Cd Schottky diode (SD) has been investigated in the temperature range of 40–360 K with a temperature step of 10 K under dark conditions. The characteristic parameters of the SD such as barrier height, ideality factor and series resista…
The structure and thickness of zinc and cadmium chalcogenide semiconductor films are studied by X-ray radiography. The film thickness is shown to be comparable with the half-value layer depth. The electrical conductivity of the films increases upon heating in the hydrogen atmosphere and decreases upon heating in carbo…
The ratios of emission probabilities were determined by using the measured K shell X-ray intensity ratio values for elements from Sc to Zn. For the experimental measurements, the samples were excited by 59.5 keV γ rays from a 241Am annular radioactive source. The emitted K X-rays from the samples were counted by an Ul…
Polypropylene has a great electrical property and may be used as primary insulating material in electrical power cable. In cable accessory, the field distribution is often distorted since the very complicated physical structure, which makes interface discharge between PP and cable joint insulation easy to happen. Poly…
High-loading electrodes play a crucial role in the practical applications of high-energy-density batteries,which are especially challenging for lithium–sulfur (Li–S) batteries. Herein, a mechanically robust network binder was constructed by weaving dual biopolymers (i.e., guar gum and xanthan gum) via the intermolecul…
Network-on-Chip (NoC) is the interconnect of choice for many-core processors and system-on-chips in general. Most of the existing NoC designs focus on the performance with respect to average throughput, which makes them less applicable for real-time applications especially when applications have hard timing requiremen…
4-(2-hydroxyphenoxy) phthalic nitrile was prepared by the nucleophilic substitution reaction of catechol and 4-nitro phthalic nitrile in DMF with the existence of N 2 and K 2 CO 3 .The optimal reaction conditions were obtained as follows: the mole ratio of catechol, K 2 CO 3 and 4-nitro phthalic nitrile is 2:1:1, with…
The onsite teams at NASA’s Michoud Assembly Facility in New Orleans are making steady progress as they continue with recovery efforts from Tuesday’s tornado strike. The primary goal is to bring all facility systems including power and utilities online and have them fully functioning as soon as possible.
Composites are materials which are widely used in aerospace industry for its high strength to weight ratio, where most of the alloys add weight as penalty. These composites are made up of two phases namely matrix phase and reinforcement phase. Matrix is the most important phase as it has to hold the reinforcement and…
Most of the brake liners used is based on metal fiber reinforced phenol formaldehyde resin, which is a composite of 15–20 constituents and is generally called semi metallic brakes. In practice, asbestos, antimony, and their modified version of organic composite brakes are used which possess good strength, resistance t…
