Different metal (Mn, Fe, Co, Ni, and Zr) decorated Cu/CeO catalysts for efficient CO oxidation in a rich CO/H atmosphere.

In this work, CuM/CeO (M = Mn, Fe, Co, Ni, and Zr) catalysts with a low Cu content of 1 wt% were purposely designed and prepared using the co-impregnation method. The samples were characterized using various techniques (TG-DTA, XRD, N-adsorption/desorption measurements, H-TPR, XPS and Raman spectroscopy) and CO preferential oxidation (CO-Prox) under H/CO-rich conditions was performed. The results have shown that enhanced catalytic performance was achieved upon the introduction of Mn, Co and Ni, and little impact was observed with Zr doping, but Fe showed a negative effect, as compared with the Cu/CeO catalyst.

Enhanced Aluminum-Ion Storage Properties of N-Doped Titanium Dioxide Electrode in Aqueous Aluminum-Ion Batteries.

Aqueous aluminum-ion batteries (AIBs) have great potential as devices for future large-scale energy storage systems due to the cost efficiency, environmentally friendly nature, and impressive theoretical energy density of Al. However, currently, available materials used as anodes for aqueous AIBs are scarce. In this study, a novel sol-gel method was used to synthesize nitrogen-doped titanium dioxide (N-TiO) as a potential anode material for AIBs in water.

Manipulating OH -Mediated Anode-Cathode Cross-Communication Toward Long-Life Aqueous Zinc-Vanadium Batteries.

The anode-cathode interplay is an important but rarely considered factor that initiates the degradation of aqueous zinc ion batteries (AZIBs). Herein, to address the limited cyclability issue of V-based AZIBs, Al (SO ) is proposed as decent electrolyte additive to manipulate OH -mediated cross-communication between Zn anode and NaV O  ⋅ 1.5H O (NVO) cathode.

[Ultrasound-guided local injection of dexamethasone and lidocaine into subcapsule for subacute thyroiditis].

To compare the efficacy and safety of ultrasound-guided local injection of the mixture of dexamethasone（DEX） with lidocaine and oral prednisolone（PSL） in treating patients with subacute thyroiditis. Ninety-three patients with subacute thyroiditis were divided into group A（=48） and Group B（=45）. Group A was treated with ultrasound-guided subcapsular injection in thyroid lesion area, while group B was treated with oral medication.

Phosphorus-Doping-Induced Surface Vacancies of 3D Na Ti O Nanowire Arrays Enabling High-Rate and Long-Life Sodium Storage.

Sodium-ion batteries have attracted interest as an alternative to lithium-ion batteries because of the abundance and cost effectiveness of sodium. However, suitable anode materials with high-rate and stable cycling performance are still needed to promote their practical application. Herein, three-dimensional Na Ti O nanowire arrays with enriched surface vacancies endowed by phosphorus doping are reported.

Ru Se@MoS hybrid as a highly efficient electrocatalyst toward hydrogen evolution reaction.

Alkaline hydrogen evolution reaction (HER) requires highly efficient and stable catalytic materials, the engineering of which needs overall consideration of the water dissociation process as well as the intermediate hydrogen adsorption process. Herein, a Ru Se@MoS hybrid catalyst was synthesized by the decoration of MoS with Ru Se nanoparticles through a two-step hydrothermal reaction. Due to the bifunctionality mechanism in which Ru promotes the water dissociation and the nearby Se atoms, unsaturated Mo and/or S atoms act as active sites for the intermediate hydrogen adsorption, the hybrid catalyst exhibits an exceptional HER performance in basic media with a rather low overpotential of 45 mV at a current density of 10 mA cm and a small Tafel slope of 42.

Technique for endoscopic thyroidectomy with selective lateral neck dissection via a chest-breast approach.

Background: Endoscopic thyroidectomy has been widely accepted because it can effectively avoid neck scarring. However, there are seldom reports concerning completely endoscopic lateral neck dissection approaches. In this study, we introduced a technique for performing endoscopic thyroidectomy with lateral neck dissection via a chest-breast approach.

Hierarchical GeP/Carbon Nanocomposite with Dual-Carbon Conductive Network as Promising Anode Material for Sodium-Ion Batteries.

Due to the Earth's scarcity of lithium, replacing lithium with earth-abundant and low-cost sodium for sodium-ion batteries (SIBs) has recently become a promising substitute for lithium-ion batteries. However, the shortage of appropriate anode materials limits the development of SIBs. Here, a dual-carbon conductive network enhanced GeP (GeP/acetylene black/partially reduced graphene oxide sheets (GeP/AB/p-rGO)) composite is successfully prepared by a facile ball milling method.

In Situ Encapsulating α-MnS into N,S-Codoped Nanotube-Like Carbon as Advanced Anode Material: α → β Phase Transition Promoted Cycling Stability and Superior Li/Na-Storage Performance in Half/Full Cells.

Incorporation of N,S-codoped nanotube-like carbon (N,S-NTC) can endow electrode materials with superior electrochemical properties owing to the unique nanoarchitecture and improved kinetics. Herein, α-MnS nanoparticles (NPs) are in situ encapsulated into N,S-NTC, preparing an advanced anode material (α-MnS@N,S-NTC) for lithium-ion/sodium-ion batteries (LIBs/SIBs). It is for the first time revealed that electrochemical α → β phase transition of MnS NPs during the 1st cycle effectively promotes Li-storage properties, which is deduced by the studies of ex situ X-ray diffraction/high-resolution transmission electron microscopy and electrode kinetics.

Another Strategy for the Treatment of Thyroglossal Duct Cyst: Totally Endoscopic Surgery by Breast Approach.

Ischemic preconditioning prior to aortic cross-clamping protects high-energy phosphate levels, glucose uptake, and myocyte contractility.

Background: We hypothesized that indices of myocyte contractility and metabolism could be preserved with ischemic preconditioning in a model of reversible ischemia similar to that occurring during routine cardiac surgery. Regional measures of metabolism and function have not been studied in conjunction with individual myocyte function during postischemic recovery of preconditioned myocardium.

Patients And Methods: In 16 dogs, myocardium supplied by the left anterior descending artery (LAD) was preconditioned with intermittent LAD ischemia and reperfusion.
