A new class of porous materials, having hydrophobic scaffold embedded with aligned porous hydrophilic domains, was in situ fabricated through combination of emulsion‐templated method and unidirectional freezing technique. A water‐in‐oil high internal phase emulsion (HIPE) was prepared with the mixture of styrene and d…
Various nanostructures have been adopted for anti-reflection coating due to the graded refractive index. The interference between the two interfaces may sometimes cause an oscillating reflectance spectrum under certain conditions. The anti-reflection performances of a few nanostructure arrays were investigated using t…
Biodegradable foam is an alternative packaging to replace the expanded polystyrene foam packaging currently in use. Starch has been used to produce foam because of its low cost, low density, low toxicity, and biodegradability. Chitosan has been added to improve mechanical properties of product . The effect of variatio…
This work was aimed on 1) evaluating alterations of spatial structure and paramagnetic properties of brown coal (BC) caused by KOH intercalated under alkali impregnation and 2) studying KOH influence on BC thermolysis and formation of porous carbons under alkali activation in argon (800 °C, 1 h ). The spatial structur…
Multiple-phenyl phosphorous compounds are a group of chemical materials that have been used as reactants, pharmaceutical intermediates, extractants, and catalysts in organic synthetic reactions. However, the crystal growth of bulk crystals of multiple-phenyl phosphorous compounds, which may expand their applications i…
Abstract Photocontrol of enzymatic activity has become a helpful strategy to control biological processes. Herein, a method for the reversible photocontrol of lipase activity was developed by utilizing the conformational change of the lid structure. A bifunctional azobenzene derivative, whose trans/cis‐form photoisome…
We have studied the plasmon-driven photoreaction of a dual thiol-anchored o -nitrobenzyl-based photouncaging ligand on silver nanoparticles. Previous results have shown that this compound strongly anchors to gold surfaces, and a 1 J/cm 2 dose of UV light induces the intended photoreaction, uncaging an amine on the sur…
Using the B\"uttiker-Landauer formulation of transport theory in the linear response regime, the valley currents and nonlocal resistances of bilayer graphene nanostructures with broken inversion symmetry are calculated. It is shown that broken inversion symmetry in bilayer graphene nanostructures leads to striking enh…
Abstract An anisotropic double exchange interaction driven giant transport anisotropy is demonstrated in a canonic double exchange system of La2/3Sr1/3MnO3 ultrathin films epitaxially grown on NdGaO3 (110) substrates. The oxygen octahedral coupling at the La2/3Sr1/3MnO3/NdGaO3 interface induces a planar anisotropic Mn…
The size of ZnO nanorods (NRs) plays an important role in tuning the external quantum efficiency (EQE) and quality of light generated by white light emitting diodes (LEDs). In this work, we report on the enhancement of EQE and the quality of ZnO NR-based hetrojunction white LEDs fabricated on a p-GaN substrate using a…
Numerical simulations of bubble collapse show that the combined effects of air chemistry at high temperature and a stiffened gas equation of state for air at high pressures lead to significantly lower peak temperature and pressure during the evolution.
crystals. Crystallinity and ferroelectric domain structures were investigated for the PZT/LSMO heterostructure. Interestingly, relatively high non-volatile magnetoelectric coupling effects were observed in both heterostructures at room temperature. The change of chemical valence for Mn and Ti at the PZT/MgO/LSMO inter…
The glpX gene from Francisella tularensis encodes for the class II fructose 1,6-bisphosphatase (FBPaseII) enzyme. The glpX gene has been verified to be essential in F. tularensis , and the inactivation of this gene leads to impaired bacterial growth on gluconeogenic substrates. In the present work, we have complemente…
Abstract Core–shell architectures offer an effective way to tune and enhance the properties of noble‐metal catalysts. Herein, we demonstrate the synthesis of Pt shell on titanium tungsten nitride core nanoparticles (Pt/TiWN) by high temperature ammonia nitridation of a parent core–shell carbide material (Pt/TiWC). X‐r…
In this paper, doped bismuth ferrite nanoparticles with barium (Bi[Formula: see text]Ba[Formula: see text]FeO[Formula: see text], [Formula: see text] = 0.1, 0.15, 0.2) were synthesized by co-precipitation method in the presence of various surface activators. Structural properties, magnetic properties and the size of s…
PURPOSE: In principle, MR methods that exploit magnetization transfer (MT) may be used to quantify changes in the molecular composition of tissues after injury. The ability to track such changes in injured spinal cord may allow more precise assessment of the state of neural tissues. METHODS: Z-Spectra were obtained fr…
Abstract The amorphous mesoporous Ni(OH)2 hollow spheres (Ni(OH)2‐HSs) with waxberry‐like morphology were fabricated by using a facile hydrothermal method with poly(styrene‐acrylic acid) spheres as the template, followed by extraction of the template. In the hydrothermal process, Ni(NO3)2⋅6H2O was employed as the prec…
We have performed an angle-resolved photoemission spectroscopy study of ${\mathrm{BaCr}}_{2}{\mathrm{As}}_{2}$, which has the same crystal structure as ${\mathrm{BaFe}}_{2}{\mathrm{As}}_{2}$, a parent compound of Fe-based superconductors. We determine the Fermi surface of this material and its band dispersion over 5 e…
Gold nanoparticles have been of great interest because of their unique optical properties, facile synthesis and conjugation. Among various shapes of gold nanoparticles, gold nanorods have been widely studied. They can be conjugated with different molecules for biomedical applications, such as tumor imaging and therapy…
The use of molecular diagnostic techniques for bioprospecting and microbial diversity study purposes has gained more attention thanks to their functionality, low cost and quick results. In this context, ten degenerate primers were designed for the amplification of polyhydroxyalkanoate synthase (phaC) gene, which is in…
