Zinc embedded self-templated saccharide derived carbonaceous spheres proved to be multipurpose precursors for hollow, solid and double oxide spheres.
A simple electrochemical fabrication of graphene nanomesh (GNM) via colloidal templating is reported for the first time. The process involves the arraying of polystyrene (PS) spheres onto a CVD-deposited graphene, electro-deposition of carbazole units, removal of the PS template and electrochemical oxidative etching.…
A series of group 4 metal chloride complexes based on aminophenol ligands were synthesized and characterized by conventional spectroscopic techniques, elemental analysis and X-ray crystallography.
We report the design of novel filled CoSb3 skutterudite phases based on a combination of filling and Sb-substituted Ga/In defects. Ga/In doped skutterudite phases with Li-, Nd-, and Sm-fillings can be formed via this strategy, which can have relatively wider ranges of carrier concentration than other conventional fill…
Nanometer hydroxyapatite is beneficial to cucumber seeds and seedlings at concentrations less than 2000 mg L <sup>−1</sup> .
Ab initio evolutionary structural searches have been performed on SixCyO2(x+y) compounds. A novel structure, with SiC2O6 stoichiometry and the P21/c space group is calculated to be stable against decomposition within a wide pressure window from 7.2 to 41 GPa, and metastable under ambient conditions. It consists of CO3…
Nanocomposites formed by porous silicon (PS) and zinc oxide (ZnO) have potential for applications in optoelectronic devices. However, understanding the distribution of both materials in the nanocomposite, and especially the fine structure of the synthesized ZnO crystals, is key for future device fabrication. This stud…
While Au nanocrystals (NCs) with a myriad of shapes have been successfully prepared with good uniformity and in high yield, Au right bipyramids (RBPs) with a single-twinned structure have been elusive. For the first time, we report a facile route for the synthesis of truncated Au RBPs with shape purity >90% and sizes…
We report lanthanide-based micelles integrating hypericin （Hyp） for X-ray- triggered photodynamic therapy （PDT）. The lanthanide luminescence induced by X-ray irradiation excites the photosensitizer, which leads to the generation of singlet oxygen. This versatile approach can be extended to other photosensitizers or ot…
The dielectric properties of polymorphic tungsten-bronzes, β-SrTa2O6 and β′-SrTa2O6, were measured using phase pure ceramic specimens. The room temperature dielectric constant (κ) of β-SrTa2O6 and β′-SrTa2O6 were ≈26 and ≈104, respectively, which were relatively constant over the ac frequency range, 102–106 Hz. The ma…
The present study reports zero-order controlled release drug-loaded nanofibers fabricated using a modified coaxial electrospinning,in which a 2%(weight/volume)dilute solution of polyacrylonitrile(PAN)was exploited as a sheath fluid.With PAN and acyclovir(ACY)as the filament-forming matrix and active pharmaceutical ing…
Making Drugs Safer: Improving Drug Delivery and Reducing Side-Effect of Drugs on the Human Biochemical System Abstract The Re-strategizing becomes inevitable when in trying to proffer solution to a problem damage in a different form is done. The unintended effects of drugs (side effects) could be leaving behind more d…
The thermal conductivities of quaternary Mg-Zn-Ca-Y alloys have been investigated by evaluating the effect of adding Y on the Mg-4Zn-0.5Ca alloys, with an emphasis on developing new Mg alloys without compromising their thermal conductivities, processabilities, and mechanical properties.In this study, to improve the me…
Paperboard is an environment-friendly multi-layer material widely used for packaging applications. However, for food packaging paperboard lacks essential barrier properties towards oxygen and water vapor. Conventional solutions to enhance these barrier properties (e.g. paperboard film coating with synthetic polymers)…
The geometric structural optimization, electronic band structure, total density of states for valence electrons, density of states for phonons, optical, dynamical, and thermodynamical features of cesium chloride have been investigated by linearized augmented plane wave method using the density functional theory under…
In this paper, we demonstrate a novel carbon nanotube (CNT) reinforced macroporous adsorption resin (MAR) for the first time. The CNTs were dispersed in water via sonication, and then in situ physically entrapped in the pores of MAR by capillary forces and sonication. The resulting CNT reinforced MAR (CNT-MAR) was pro…
The development of hybrid nanostructures in the nanocomposite significantly increases the air impermeability, electrical, and thermal conductivity. Interestingly, it bridges to increase the path of diffusion and conduction.
