Synthesis of in-plane MoC/MoO heterostructures by a novel spatial-confined partial oxidation approach for enhanced TEA sensing.

In-plane heterostructures exhibit extraordinary chemical and electron transfer properties, which have received remarkable research attention. However, the synthesis of an in-plane MoC/MoO heterostructure has been rarely reported, and the deep investigation of the effect of its fine structure on reactivity is of great significance. Notably, the in-plane heterostructures endow the material with abundant grain boundaries, which facilitate the formation of surface acid sites and active oxygen species, thus contributing to the sensing performance.

Engineering of in-plane SnS-SnO nanosheets heterostructures for enhanced HS sensing.

In-plane heterostructures has attracted considerable interest due to exceptional electron transport properties, high specific surface area, and abundant active sites. However, synthesis of in-plane SnS-SnO heterostructures are rarely reported, and the deep investigation of the fine structure on reactivity is of great significance. Here, we propose partial in-situ oxidation strategy to construct the in-plane SnS-SnO heterostructures and the surface properties, the ratio of two components can be finely tuned by precisely adjusting the treatment temperature.

Oxygen Vacancy Enabled Electronic Structure Engineering of Pt-WO Nanosheets toward Highly Efficient BTEX Sensing.

A Pt nanoparticle-immobilized WO material is a promising candidate for catalytic reactions, and the surface and electronic structure can strongly affect the performance. However, the effect of the intrinsic oxygen vacancy of WO on the d-band structure of Pt and the synergistic effect of Pt and the WO matrix on reaction performance are still ambiguous, which greatly hinders the design of advanced materials. Herein, Pt-decorated WO nanosheets with different electronic metal-support interactions are successfully prepared by finely tuning the oxygen vacancy structure of WO nanosheets.

Ultra-sensitive HS sensor based on sunflower-like In-doped ZnO with enriched oxygen vacancies.

Metal oxide sensors face the challenge of high response and fast recovery at low operating temperatures for the detection of toxic and flammable hydrogen sulfide (HS) gases. Herein, novel In-doped ZnO with a sunflower-like structure and tunable surface properties was rationally synthesized. The substitutional In atom in the ZnO crystal can dramatically enhance the concentration of oxygen vacancies (O), the In-ZnO sites are responsible for fast recovery, and the formation of sub-stable sulfide intermediates gives rise to the high response towards HS.

Advances in Doped ZnO Nanostructures for Gas Sensor.

Gas sensors based on metal oxides semiconductor (MOS) have attracted extensive attention from both academic and industry. ZnO, as a typical MOS, exhibits potential applications in toxic gas detection, owning to its wide band gap, n-type transport characteristic and excellent electrical performance. Meanwhile, doping is an effective way to improve the sensing performance of ZnO materials.

Ultrathin agaric-like ZnO with Pd dopant for aniline sensor and DFT investigation.

Aniline detection is of great importance in many industries, but most of the aniline sensors suffers from tedious and time consuming process. Herein, we present an efficient aniline sensor based on Pd decorated ZnO nanomaterials. Ultrathin ZnO nanosheets were synthesized by a facile one-step hydrothermal method.

Double-platelet Pd@ZnO microcrystals for NO chemical sensors: their facile synthesis and DFT investigation.

Double-platelet, single-platelet and spherical ZnO microcrystals were fabricated via a facile and controllable hydrothermal method. The morphology of the ZnO microcrystals and the exposure ratio of the (001) crystal surface were regulated by adjusting the pH of the solution. The ZnO microcrystals were modified with Pd nanoparticle loading by simple calcining, and the interaction of Pd nanoparticles (NPs) on the ZnO crystal surface increased its oxygen vacancy content.

Gamma Knife Surgery for Recurrent Trigeminal Neuralgia in Cases with Previous Microvascular Decompression.

Background: Microvascular decompression (MVD) and Gamma Knife surgery (GKS) are the primary treatments for trigeminal neuralgia (TN). However, many patients require further surgical treatment after initial surgery for recurrent TN. The aim of this study was to evaluate efficacy and safety of GKS for recurrent TN cases with prior MVD.

Micro lesion effect of the globus pallidus internus with deep brain stimulation in Parkinson's disease patients.

Background: The micro-lesion effect (MLE) has been observed in many Parkinson's disease (PD) patients after deep brain stimulation (DBS) surgery. For subthalamic nucleus (STN) stimulation, the MLE has been reported as a predictor of the long-term efficacy of DBS. However, the research on the MLE in the globus pallidus internus (GPi) is insufficient.
