Natural gas can be reformed to syngas (CH4 + H2O = CO + 3H2), at temperatures above 850°C. Membrane catalytic reformers can provide high CH4 conversions at temperatures below 650°C, by separating H2 from the reactive mixture. Traditional Ni‐based catalysts suffer from low activity at low temperatures and deactivate ra…
Interfacial layers play a critical role in building up the Ohmic contact between electrodes and functional layers in organic photovoltaic (OPV) solar cells. These layers are based on either inorganic oxides (ZnO and TiO 2 ) or water-soluble organic polymers such as poly[(9,9-dioctyl-2,7-fluorene)- alt -(9,9-bis(3′-( N…
BACKGROUND: More than 60% of the active pharmaceutical ingredients, which are classified as Biopharmaceutics Classification System class II. The limited solubility of these drug may lead to low therapeutic effects. METHODS: Nanoprecipitation presents some advantages because it is a straightforward method with low-cost…
AbstractMaterial exploitation, especially the use of sand as the main component of concrete, needs to be reduced. The purpose of this research is to find out the value of compressive strength from the addition of rocks to achieve compressive strength according to the standard mix design of paving blocks. This research…
Abstract Three types of multilayer flyer energy conversion elements (MFECEs) through integrating different laser pulse absorption/ablation layer of nano-film materials into a laser-driven flyer plates between thermal barrier of alumina and transparent substrate have been investigated in this study. The relationships a…
The direct torque control system has excellent dynamic performance of electromagnetic torque; however, the dynamic performance of the speed is affected by the proportional-integral parameters of the speed closed loop. Hence, a control method which can realize the optimal dynamic performance of the speed is investigate…
A series of CoMo catalysts supported on various Al 2 O 3 supports added with TiO 2 were prepared to investigate the addition effect of TiO 2 on formation of an active phase on sulfided CoMo/Al 2 O 3 catalyst. The catalytic activity tests were carried out with hydrodesulfurization (HDS) of 4,6-dimethyldibenzothiophene,…
Abstract There is only one family of room‐temperature luminescent radicals, the triphenylmethyl radicals, to date. Herein, we synthesize a new stable room‐temperature luminescent radical, (N‐carbazolyl)bis(2,4,6‐tirchlorophenyl)methyl radical (CzBTM), which has improved properties compared to the triphenylmethyl radic…
The Cl substitution reactions of the N/N (1‐3) and N/O (4 and 5) spirocyclic monoferrocenylphosphazenes with 1,4‐dioxa‐8‐azaspiro[4,5]decane (DASD) produce the mono‐ (1a‐5a), geminal‐ (1b‐5b) and tetrakis‐DASD‐substituted ferrocenylspirocyclotriphosphazenes (1c‐5c). The mono‐ and geminal‐DASD‐substituted phosphazenes…
A number of primary ores such as phosphate rock, gold-, copper- and rare earth ores contain considerable amounts of accompanying uranium and other critical materials. Energy neutral mineral processing is the extraction of unconventional uranium during primary ore processing to use it, after enrichment and fuel product…
A zeroth-order-mode circular microstrip patch antenna is presented, consisting of two axial symmetrical semi-circulars and pins, which are in essential two composite right/lefthanded metamaterial unit cells. The patch-like radiation pattern was achieved for the zeroth-order mode by modifying the equivalent magnetic cu…
Abstract Various graphene-based Si nanocomposites have been reported to improve the performance of active materials in Li-ion batteries. However, these candidates still yield severe capacity fading due to the electrical disconnection and fractures caused by the huge volume changes over extended cycles. Therefore, we h…
All the compositions in the (1−x)Mg0.95Ni0.05Ti0.98Zr0.02O3–xCa0.6La0.8/3TiO3 (0 ≤ x ≤ 0.2) series were fabricated using solid state sintering route. Mg0.95Ni0.05Ti0.98Zr0.02O3 possessed excellent microwave dielectric properties with ε r ≈ 17.1, Q u f0 ≈ 195855 GHz, and τ f ≈ -46 ppm/°C. τ f was tuned through zero by…
Abstract Biocompatible microcapsules with a function of pH‐triggered release are promising for the site‐specific release of bio‐actives in the human body. In this work, smart microcapsules with three distinct configurations of membranes are produced to control the rate of pH‐triggered release. The microcapsules are pr…
Med15 is an important subunit of Mediator Tail module and is characterized by a KIX domain present towards amino terminal. In yeast and metazoans, Med15 KIX domain has been found to interact with various transcription factors regulating several processes including carbohydrate metabolism, lipogenesis, stress response…
Emulsion polymerization is a polymerization process with different applications on the industrial and academic scale. It involves application of emulsifier to emulsify hydrophobic polymers through aqueous phase by amphipathic emulsifier, then generation of free radicals with either a water or oil soluble initiators. I…
Abstract Power‐to‐gas technologies, combining hydrogen produced by water electrolysis with carbon dioxide to produce substitute natural gas (SNG), can support the increased penetration of renewable electricity sources. However, the technical and economic feasibility of these technologies requires the conversion effici…
Abstract Ni‐rich cathode materials have high capacities but exhibit serious capacity attenuation. Therefore, a strategy for modifying a LiNi0.8Co0.1Mn0.1O2 cathode material by Na doping of the Li+ sites is proposed to improve its electrochemical performance. In this work, Li1−xNaxNi0.8Co0.1Mn0.1O2 (x=0, 0.01, 0.03) ma…
Graphene grain boundaries (GBs) and other nanodefects can deteriorate electronic properties. Here, using transient absorption (TA) microscopy we directly visualized GBs by TA intensity increase due to change in density of state. We also observed a faster decay due to defect-accelerated carrier relaxation in the GB are…
In most unconventional superconductors, like the high-T_{c} cuprates, iron pnictides, or heavy-fermion systems, superconductivity emerges in the proximity of an electronic instability. Identifying unambiguously the pairing mechanism remains nevertheless an enormous challenge. Among these systems, the orthorhombic uran…
