The rapid emergence of gallium-nitride (GaN) light-emitting diodes (LEDs) for solid-state lighting has created a timely opportunity for optical communications using visible light. One important challenge to address this opportunity is to extend the wavelength coverage of GaN LEDs without compromising their modulation…
Abstract Continuous and intergrown metal‐organic framework (MOF) membranes, MIL‐100(In) (MIL represents Materials Institute Lavoisier), were prepared directly on porous anodic alumina oxide (AAO) membranes using an in situ crystallization method. The pore surface of MIL‐100(In) is conferred with polarity due to the pr…
The Kossel–Stranski model of crystal growth has been adopted to study freezing and melting of fluids in mesoporous materials. The model is found to exhibit the key features observed in the experiments, including shifted solid–liquid and liquid–solid transition temperatures, irreversibility between freezing and melting…
Seven coordination polymers {[M(L)2(H2O)2]·(NO3)2}n (M = Co (1), Ni (2), Cd (3)) and [M(L)(ox)]n (M = Co (4), Ni (5), Zn (6), and Mn (7)) have been synthesized (L = 2,6-bis(imidazol-1-yl)pyridine, ox = oxalate) under hydrothermal conditions. Single-crystal X-ray diffraction analysis has revealed that 1–3 are isomorpho…
We propose a microscopic approach to derive angular dependent critical current density Jc(θ) of YBCO films with c-axis correlated nanorods, based on the energy gain by pinning. Results are in good agreement with experimental ones. Irreversibility fields and Jcin YBa2Cu3O7-xthin films containing segmented BaSnO3nanorod…
Controlling single-particle wave functions in single semiconductor quantum dots is in demand to implement solid-state quantum information processing and spintronics. Normally, particle wave functions can be tuned transversely by an perpendicular magnetic field. We report a longitudinal wave function control in single…
Gas-liquid interfaces are omnipresent in daily life, and processes involving these interfaces are the basis for a broad range of applications that span from established industrial processes to modern microengineering, technology, and medical applications for diagnosis and treatment. Despite the rapid progress in under…
The thermodynamic driving forces behind small molecule-protein binding are still not well-understood, including the variability of those forces associated with different types of ligands in different binding pockets. To better understand these phenomena we calculate spatially resolved thermodynamic contributions of th…
We investigate the impact of pH on the swelling properties of thermoresponsive microgel layer-by-layer films. Microgels were synthesized from N -isopropylacrylamide and/or N -isopropylmethacrylamide. At pH 3, films composed of traditional (core) microgels, where acrylic acid has been copolymerized throughout the micro…
The origins of differential catalytic reactivities of four Rh(I) catalysts and their derivatives in the (5 + 2) cycloaddition reaction were elucidated using density functional theory. Computed free energy spans are in excellent agreement with known experimental rates. For every catalyst, the substrate geometries in th…
Abstract The intermetallic Heusler compounds with ScT2Al and Sc(T0.5T′0.5)2Al composition with T = T' = Ni, Pd, Pt, Cu, Ag, Au were synthesized from the elements by arc melting. They crystallize in the cubic MnCu2Al type structure, space group Fm$\bar{3}$ m. The unit cell parameters were determined by powder X‐ray dif…
An atmospheric-pressure N 2 –Ar plasma is investigated by means of optical emission spectroscopic diagnosis concerning the variation of its fundamental parameters, electron density and plasma temperature, and concentrations of ionized molecular nitrogen, atomic nitrogen, and excited argon with the tuning variables, su…
A novel low-cost and efficient counter electrode (CE) was obtained by treating catalytic inert tungsten trioxide (WO3) nanomaterial in NH3 atmosphere at elevated temperatures. The formation of tungsten oxynitride from WO3 after NH3 treatment, as evidenced by X-ray photoelectron spectroscopy and X-ray diffraction, incr…
A series of metal–organic frameworks (MOFs) were systematically synthesized through a solvent-ratio-controlled assembly: {[Et 2 NH 2 ] 2 [Zn 5 (L) 2 (H 2 O) 4 ]·2C 2 H 5 OH·2H 2 O} n ( 1 ), {[Et 2 NH 2 ] 4 [Zn 7 (HL) 2 (H 2 L) 2 ]·4C 2 H 5 OH·6H 2 O} n ( 2 ), {[Et 2 NH 2 ] 4 [Zn 6 (L) 2 (H 2 L)(H 2 O) 2 ]·2C 2 H 5 OH·…
Grand canonical Monte Carlo (GCMC) simulations of hydrogen sorption were performed in In- soc -MOF, a charged metal–organic framework (MOF) that contains In 3 O trimers coordinated to 5,5′-azobis(1,3-benzenedicarboxylate) linkers. The MOF contains nitrate counterions that are located in carcerand-like capsules of the…
The use of programmed electrical signals to influence biological events has been a widely accepted clinical methodology for neurostimulation. An optimal biocompatible platform for neural activation efficiently transfers electrical signals across the electrode-cell interface and also incorporates large-area neural guid…
Ultrasonic technology is a promising tool for washing oily sludge to recover oil. In this study, the influence of ultrasonic conditions on the removal of different oil components from oily sludge was investigated to optimize ultrasonic washing technology. Among the three frequencies (25, 50 and 100 kHz) applied, ultra…
It is demonstrated that hydroxyapatite, a type of calcium phosphate commonly found in bone tissue, retains surprisingly large stored charge when synthesized electrochemically from aqueous solution. Thin films of hydroxyapatite formed on titanium and stainless steel electrodes were found to display giant polarization w…
Conversion to ammonia with Haber–Bosch catalysts can be increased above 95% by selective absorption of ammonia by MgCl 2 . The maximum conversion depends on reaction and absorption equilibria. At very short times, the measured conversion rate is the same with and without absorption by the MgCl 2 salt; the overall rate…
