Spherical atoms have the highest geometrical symmetry. Due to this symmetry, atomic orbitals are highly degenerate, leading to closed-shell stability and magnetism. No substances with greater degrees of degeneracy are known, due to geometrical limitations. We now propose that realistic magnesium, zinc, and cadmium clu…
<div class="section abstract"><div class="htmlview paragraph">Experimental studies were carried out to investigate the effect of soot deposition on NOx purification phenomena in an ammonia selective catalytic reduction coated diesel particulate filter (SCR/DPF) catalyst. To study soot deposition effects on…
To clarify the effect of rust on the corrosion of steel exposed to an atmosphere containing chloride, the electrochemical reduction and re‐oxidation behavior of α, β, and γ‐FeOOH is studied. Films are formed on gold electrodes and are electrochemically reduced at several potentials, thus simulating the corrosion poten…
This study evaluated the removal of silver nanoparticles (AgNPs), coated with different stabilizers, from aqueous media using the electrocoagulation technique. The AgNPs dispersions were synthesized by chemical reduction with silver nitrate as precursor, sodium borohydride as reducing agent and sodium carboxymethylcel…
We present a quantitative physical model based on experimentally determined parameter values for the description of the way that dielectric breakdown occurs after a period of stressing at fields below the critical values required for deterministic theories. It is found that for most of the material lifetime isolated r…
A tunable magnetoelectric inductor composed of a symmetrical trilayer of Ga-doped NiZn ferrite and PZT in a solenoid has been developed. Under the influence of external electric/magnetic fields, the permeability variation arising from magnetostriction and piezoelectric strain in the composite results in a bidirectiona…
Transition-metal (TM)-doped solids are one of the most extensively studied compounds in the fields of catalysis, magnetism, solar cells, etc., due to their tunable optoelectronic properties that stem from TM energy-level hybridization. In this work, the hybridization of the Ni–O bond in TiO 2:Ni films was controlled i…
We report a new type of highly flexible hybrid supercapacitors (SCs) developed by graphite nanoplatelets (GNPs)-based films with a practicable fabrication method for mass production. In this report, GNP/carbon black films are featured with excellent free-standing and conductivity characteristics, thus capable of worki…
Understanding the interfacial properties of functional nanomaterials on semiconductor surfaces is crucial for developing electronics, optoelectronics, and other devices. By using graphene on the germanium (110) surface as a model, we performed scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (X…
The essence and the main contribution of this paper are consisted of the suggested novel method for estimation of a projected surface area of an irregularly shaped fragment, which represents a significant step toward a new method of an aerodynamic force estimation of a fragment motion through a resistive medium. The s…
The substitution of a pyrrolide ring for one (or more) pyridyl rings within the ubiquitous terpyridine (tpy, A ) scaffold results in more open geometries of the pyridine–pyrrolide chelate ligands. DFT calculations (B3LYP-GD3BJ/6-31G**) demonstrate that the more open geometries of the unbound ligands are mismatched wit…
Abstract A rapid one‐step microwave‐assisted liquid‐phase synthesis (MLS) method of black phosphorus (BP) is reported for the first time in this work. Under microwave irradiation, BP is generated within 45 min. The lattice spaces of the as‐prepared BP are determined as 0.338 and 0.158 nm, belonging to the (021) and (2…
Abstract Ni 3 V 2 O 8 is an archetypical multiferroic material with a kagome staircase structure of S = 1 (Ni 2+ ) spins whose complex interplay between spin ordering and ferroelectricity has been studied for more than a decade. Here, we report a new kagome staircase compound PbCu 3 TeO 7 with Cu 2+ ( S = 1/2) spins t…
Micro- and nanoscale ZnO tetrapods provide an attractive support for metallic nanostructures since they can be inexpensively produced using the flame transport method and nanoparticle synthesis schemes can take advantage of a coupled response facilitated by the formation of a semiconductor-metal interface. Here, we pr…
Dual-state emission (DSE) fluorophores with strong photoluminescence in both solution and solid states have wide applications in fluorescent probes and photoelectric devices. However, most of the existing DSE fluorophores involve complex synthetic strategies or only one or two emission colors in the solid state, which…
Abstract The ever‐increasing global demand for green energy resources calls for more research attention on the development of cheap and efficient energy storage systems. Herein, we propose the rational design of a 3D carbon foam electrode deposited with perpendicularly oriented FeCo 2 S 4 nanotubes arrays (FeCo 2 S 4…
The behavior of poly(propylene imine) dendrimers at three different solution pH is investigated through molecular dynamics (MD) simulations in explicit solvent. MD simulations provide an insight into the conformational properties of dendrimers via the evaluation of their size, shape, radial density distribution, stati…
The influence of mixing intensity on protein crystallization has been investigated for the first time in a meso oscillatory flow reactor (meso-OFR). For this, lysozyme crystallization was studied in batch at different oscillation amplitudes and frequencies. Turbidity was monitored over time to measure induction time a…
