Thermoelectric properties of bromine filled CoSb 3 skutterudite
Bromine incorporation into the skutterudite structure simultaneously lowers the thermal conductivity, tunes the carrier concentration, and preserves the high mobility of the native compound.
Three-dimensional polymer-derived ceramic/graphene paper as a Li-ion battery and supercapacitor electrode
We report synthesis and electrochemical performance of silicon-based molecular precursor-derived ceramic (PDC)/carbon nanotube-embedded graphene self-supporting composite papers as Li-ion battery and supercapacitor electrodes.
Structure–performance relationships of MnO 2 nanocatalyst for the low-temperature SCR removal of NO X under ammonia
To investigate the corresponding relationship between catalytic efficiency and structure, MnO <sub>2</sub> nanomaterials (nanospheres, nanosheets, nanorods) have been prepared successfully, and were thoroughly characterized by SEM and TEM.
Synthesis of NiO nanostructures and their catalytic activity in the thermal decomposition of ammonium perchlorate
NiO nanorods and microflowers were successfully achieved via a hydrothermal reaction without any surfactant and then a post heat treatment process. Characterization methods, such as X-ray diffraction, transmission electron microscopy and scanning electron microscopy, were employed to systematically investigate the mec…
Carbon nanotube scaffolds with controlled porosity as electromagnetic absorbing materials in the gigahertz range
Control of the microscopic structure of CNT nanocomposites allows modulation of the electromagnetic shielding in the gigahertz range. The porosity of CNT scaffolds has been controlled by two freezing protocols and a subsequent lyophilization step: fast freezing in liquid nitrogen and slow freezing at -20 °C. Mercury p…
Gold Nanoplates as Cancer-Targeted Photothermal Actuators for Drug Delivery and Triggered Release
The selective exposure of cancerous tissue to systemically delivered chemotherapeutic agents remains a major challenge facing cancer therapy. To address this question, a near infrared responsive oligonucleotide-coated (AS1411, hairpin, or both) gold nanoplate loaded with doxorubicin is demonstrated to be nontoxic to c…
Structural, thermal, dielectric and phonon properties of perovskite-like imidazolium magnesium formate
We report the synthesis and characterisation of a magnesium formate framework templated by protonated imidazole. Single-crystal X-ray diffraction data showed that this compound crystallizes in the monoclinic structure in the P21/n space group with lattice parameters a = 12.1246(4) Å, b = 12.2087(5) Å, c = 12.4991(4) Å…
Hydrothermal preparation, growth mechanism and supercapacitive properties of WO 3 nanorod arrays grown directly on a Cu substrate
Well-oriented hexagonal WO3 nanorod arrays (h-WNRs) with an average diameter of 150 ± 50 nm and a length of 2.0–3.0 μm have been successfully realized on a Cu substrate on a large scale via a simple hydrothermal method without organic additives and substrate pre-treatment. The morphology, crystallinity, atomic composi…
