Abstract In this work, a two‐step zircon method to produce zirconium oxychloride was introduced, and the alkali fusion technique with NaOH and water leaching process were investigated. The effects of the operating conditions on the decomposition of zircon were determined, and the optimal conditions are as follows: alk…
In this study, we investigated the production of hydrogen by photochemical water splitting. A multi-shaped Cu 2 O nanoparticles/MnO–MnO 2 nanorods heterojunction on a few-layer graphene-based electrode serves as the photocathode. Multi-shaped Cu 2 O nanoparticles, including truncated cubic shape, cuboctahedral shape,…
Bimodal grain structures are common in many alloys, arising from a number of different causes including incomplete recrystallization and abnormal grain growth. These bimodal grain structures have important technological implications, such as the well-known Goss texture which is now a cornerstone for electrical steels.…
In this paper, we discuss the emission of visible light by a monolithically integrated silicon gate-controlled diode with the p-n junction reverse-biased. Since the MOS-like diode utilizes the field effect to modulate the optical output, the modulation speed will benefit from this mechanism. Hence, a silicon gate-cont…
In this work, we demonstrate an one-dimensional cloak consisting of parallel-plated waveguide with two slabs of gradient index metamaterials attached to its metallic walls. In it objects are hidden without limitation of polarizations, and good performance is observed for a broadband of frequencies. The experiments at…
Nanoplasmonic materials are intensively studied due to the advantages they bring in various applied fields such as photonics, optoelectronics, photovoltaics and medicine. However, their large-scale fabrication and tunability are still a challenge. One of the promising ways of combining these two is to use the self-org…
ABSTRACT In the present study, an exact solution for free vibration analysis of piezoelectric nanobeams based on the nonlocal theory is obtained. The Euler beam model for a long and thin beam structure is employed, together with the electric potential satisfying the surface free charge condition for free vibration ana…
[Fe(tvp)2 (NCS)2 ] (1) (tvp=trans-(4,4'-vinylenedipyridine)) consists of two independent perpendicular stacks of mutually interpenetrated two-dimensional grids. This uncommon supramolecular conformation defines square-sectional nanochannels (diagonal≈2.2 nm) in which inclusion molecules are located. The guest-loaded f…
A promising general approach is proposed that enables the controlled reduction of dopants to tune the photoluminescence properties of single-phase materials. The change of oxidation state of dopants in phosphor phases leads to different emission colors that can be finely tuned. This approach was illustrated with the p…
The luminescence properties of pyrene ethenes, both as monomer and aggregate species, are found to depend on the regioisomer structure. Systematic shifts in absorption, emission, and excitation spectra of the gem ‐pyrene ethenes, both in solution and in rigid polymer hosts, are consistent with weakly interacting H‐agg…
The study of the interactions of folic acid (FA) with surface enhanced Raman scattering substrates is relevant for understanding its adsorption mechanism and for fabricating analytical devices for detection of malignant cells over‐expressing folate receptors. This paper presents a study of the adsorption of FA on silv…
The objective of this research work was to study the relationship among the apparent viscosity of bulk foam, the viscoelasticity of liquid films, and foam stability. Bulk foam tests showed that the drainage half-life of AOS foam was higher than that of sodium dodecyl sulfate (SDS) and hexadecyltrimethyl ammonium bromi…
Metal–support interaction plays a crucial role in modulating the activity and selectivity of oxide-supported metal nanoparticles in heterogonous catalysis. Zr-doped ceria is a critical component in automotive three-way catalysts. In order to understand the doping effect and Zr–CeO 2 interaction at the atomic level, he…
Stress evolution in a metal line embedded in a rigid confinement caused by the arbitrary wave-form time-dependent current loads is resolved by a direct analytic solution of the one-dimensional (1-D) Korhonen's equation. Electromigration induced stress buildup and relaxation kinetics resulted by time-dependent current…
No erasure upon reading: The development of a diaryl benzobis(thiadiazole) derivative with thermally stable isomers that can be isolated owing to intramolecular steric hindrance is summarized in this Highlight. Practically useful photochromic switches that do not suffer from erasure upon reading have thus been fabrica…
Widespread use of silver nanoparticles raises questions of environmental and biological impact. Many synthesis approaches are used to produce pure silver and silver-shell gold-core particles optimized for specific applications. Since both nanoparticles and silver dissolved from the particles may impact the biological…
We present an in situ cryo-electron microscopy (cryoEM) study of mixed poly(acrylic acid) (PAA)/polystyrene (PS) brush-grafted 67 nm silica nanoparticles in organic and aqueous solvents. These organic-inorganic nanoparticles are predicted to be environmentally responsive and adopt distinct brush layer morphologies in…
We studied the formation of microstructured films at liquid surfaces via vapor phase polymerization of cross-linked polymers. The films were composed of micron-sized coral-like structures that originate at the liquid-vapor interface and extend vertically. The growth mechanism of the microstructures was determined to b…
We grow dense carbon nanotube forests at 450 °C on Cu support using Co/Al/Mo multilayer catalyst. As a partial barrier layer for the diffusion of Co into Mo, we apply very thin Al layer with the nominal thickness of 0.50 nm between Co and Mo. This Al layer plays an important role in the growth of dense CNT forests, pa…
Abstract Ferroelectrics in metal?organic materials have attracted recent interest owing to their synthetic simplicity and tunable nature. Utilizing isomeric dipodal phosphoramide ligands, L1 [PhPO(NH4Py)2] and L2 [PhPO(NH2Py)2], two new CuIIL2 derivatives, 1 ({[CuL12(H2O)2]?(NO3)2?(H2O)1.5?(CH3OH)}?) and 2 ([CuL22]?(N…
