As substitutes for graphite, the negative electrode material commonly used in Li-ion batteries, hydrides have the potential to overcome both safety and performance limits of the current state-of-the-art Li-ion cells. Hydrides can operate through a conversion process proved for some interstitial hydrides like MgH2: MxA…
An inorganic nickel oxide coating that enables the use of small bandgap semiconductors that can efficiently absorb solar spectrum for efficient solar driven water oxidation is reported by Nathan S. Lewis and co-workers in article number 1402276. This multifunctional coating is optically transparent, index matched for…
Nano-carbon materials are promising for use in future electronic devices. Their superior properties are derived from the low dimensional structure based on the two dimensional carbon (graphene) sheet. Carbon nanowalls (CNWs) are nano-carbon materials comprising a few layers of graphene. However, controlling the positi…
Due to tunable luminescence and absorption spectra, high quantum yield, compatibility with various technologies and materials colloidal quantum dots (QDs) are attracting much interest in various fields of science and engineering, such as light emitting devices, photovoltaics and catalysis. Because of superior photosta…
Bending and shear stiffness, which are used as deformation resistance indexes, are very important mechanical properties of bamboo-wood sandwich composites. Thus, a new methodology to calculate the elastic constants of this type of material was proposed in this paper. First, the elastic constants of the composites were…
On page 2518, drug nanodots of ultra-small sizes (around 10 nm) are prepared by W. Wei, G. Ma, and co-workers. After decoration with iRGD ligands, these nanodots are demonstrated to possess superior ability in intratumoral infiltration over their counterparts with larger sizes (70 nm). Efficient cancer stem cell elimi…
For a polymeric nanocomposite based stress sensor it is always desirable to get conductivity at very low percolation threshold, which is the critical concentration of conductive filler necessary to initiate a continuous conductive network. We describe here a piezoresistive carbon black (CB)-polymeric nanocomposite wit…
In this paper two independent inverters are used to extend the Constant Power Speed Region (CPSR) for a concentrated open winding IPM synchronous motor (IPMSM). The IPMSM uses a v-shaped magnet arrangement on the rotor and is optimized to provide constant power over a speed range up to eight times rated speed. The cir…
Graphene has been considered for a variety of applications including novel nanoelectronic device concepts. However, the deposition of ultra-thin high-k dielectrics on top of graphene has still been challenging due to graphene's lack of dangling bonds. The formation of large islands and leaky films has been observed re…
We have compared device performance of monolayer and bilayer BP FETs based on atomistic quantum transport simulations. This study reveals that, although monolayer BP FETs are robust against short-channel effects at Lch10 nm) without losing steep switching characteristic. Our benchmark against ITRS 2022 shows that BP F…
Mesoporous resorcinol-formaldehyde (RF) xerogels were difficult to obtain by conventional sol-gel polymerization at atmospheric pressure because the resulting tenuous RF-gel structures tended to shrink or collapse during subsequent hot-air drying. To avoid this problem, costly and energy-intensive supercritical drying…
A new method for the analysis of partial discharges (PD), which are used as an indicator for insulation quality in electrical apparatuses, is evaluated for corona discharges at DC voltage. This method targets pattern generation for DC PD similar to the well-known AC PD diagnostic method called phase-resolved partial d…
Abstract Transparent, light yellow single crystals of the barium chloride nitridotantalate(V) Ba3Cl2TaN3 (hexagonal, P63cm; a = 1507.39(8) pm, c = 632.98(3) pm, c/a = 0.420; Z = 6) are obtained by the reaction of the barium azide chloride Ba(N3)Cl or its ternary decomposition products with the container wall of arc‐we…
Summary form only given. Graphene is known for its high carrier mobility and high saturation velocity . The majority of graphene transistors in the literature-including MOSFETs, barristors, and tunneling FETs-have a gate separated from the channel by a conventional or high-K dielectric layer. In this paper we demonstr…
In article number 1500357, Guosheng Li, Jin Y. Kim, and co-workers report a remarkably reliable Na-FeCl2 ZEBRA battery for stationary energy storage applications. The removal of surface oxide passivation layers on iron particles is critical and it is attributed to polysulfide species generated from sulfur-based additi…
In this study the results of optical, electrical and photovoltaic experiments which were carried out to investigate the memory effect of TlGaSe2 ferroelectric – semiconductor with incommensurate (INC) - phase are presented. The aim is to show that electrical and open circuit photovoltage measurements can be effectivel…
This paper reports a microheater-based combustible gas sensor with ultra-low power consumption (1.4 mW) using pulsed heating and novel sensing materials. High surface area graphene aerogel is used as a support for platinum and palladium nanoparticles. Pulsed heating (450 °C) at a 10% duty cycle yields an order of magn…
Current harmonics injected in the utility by nonlinear loads tend to deteriorate the power quality at the mains. These harmonics are compensated by Shunt Active Power Filters (SAPF). Current error space phasor based hysteresis controller for SAPF is presented in this paper, which allows precise compensation of harmoni…
Summary form only given. In conclusion, we investigated the effects of gamma-ray irradiation and low temperature on the device performance of sol-gel derived ZnO thin-film transistors. In both cases, the degradation of the device performance was observed. In the case of radiation study, further investigation is needed…
ABSTRACT BACKGROUND Proteins aggregation, which leads to their inactivation, is a major concern in cell biology and the biotechnological industry. Addition of small molecules to protein media is a simple way to counteract this problem, and the search for more effective molecules still continues. Alpha‐amylases (EC 3.2…
