<h3>Importance</h3> In adults undergoing hip fracture surgery, regional anesthesia may reduce postoperative delirium, but there is uncertainty about its effectiveness. <h3>Objective</h3> To investigate, in older surgical repair for fracture, the effects of on incidence delirium compared with general anesthesia. <h3>Design, Setting, and Participants</h3> A randomized, allocation-concealed, open-label, multicenter clinical trial 950 patients, aged 65 years older, or without preexisting...
The solid-solution metal oxide (NiMgCuZnCo)O is the first known high-entropy (HE) synthesized, forming a poster child of emerging materials, which derived from high-temperature synthesis methodologies (>900 °C). In this work, we report mechanochemical HE under ambient conditions. advantage approach was further demonstrated by introduction up to 5 wt % noble into (NiMgCuZnCo)O, as single atoms or nanoclusters, showed good stability at high temperature and produced catalytic activity in...
The electrocatalytic nitrogen reduction reaction (NRR) on metal-free catalysts is an attractive alternative to the industrial Haber-Bosch process. However, state-of-the-art electrocatalysts still suffer from low Faraday efficiencies and ammonia yields. Herein, we present a molecular design strategy develop defective boron carbon nitride (BCN) catalyst with abundant unsaturated B N atoms as Lewis acid base sites, which upgrades single "Lewis catalysis" "frustrated pairs (FLPs) catalysis." 14...
We have investigated the defect perovskites A3M2I9 (A = Cs, Rb; M Bi, Sb) as materials for radiation detection. The phase purity of Bridgman-grown single crystals was confirmed via high-resolution synchrotron X-ray diffraction, while density functional theory calculations (DFT) show surprisingly dispersive bands in out-of-plane direction these layered materials, with low effective masses both holes and electrons. Accordingly, each four showed response to 241Am α-particle irradiation hole...
Abstract Semiconductors with very low lattice thermal conductivities are highly desired for applications relevant to energy conversion and management, such as thermoelectrics barrier coatings. Although the crystal structure chemical bonding known play vital roles in shaping heat transfer behavior, material design approaches of lowering conductivity using principles uncommon. In this work, an effective strategy weakening interatomic interactions therefore suppressing based on is presented a...
As a potential alternative to petroleum-derived terephthalic acid (TPA), the general production of 2,5-furandicarboxylic (FDCA) through 5-hydroxymethylfurfural (HMF) oxidation has fallen short industrial expectations due HMF's storage instability and cost. Here, we propose strategy involving Ru cation coordination manipulation achieve efficient 5-methoxymethylfurfural (MMF) FDCA by constructing Ru–Ce paired site on CeO2-doped hydroxyapatite precursor (CeO2–HAP). By optimizing reaction...
We demonstrate a potential candidate, the 0D "all-inorganic" perovskite material Cs2TeI6, as sensitive all-inorganic X-ray photoconductor for development of new generation direct photon-to-current conversion flat-panel imagers. Cs2TeI6 consists high atomic number elements, has electrical resistance, and exhibits air moisture stability, making it suitable photoconductor. In addition, we identify that film can be prepared under low-temperature process using electrostatic-assisted spray...
Strong metal-support interaction (SMSI) is recognized as a pivotal strategy in hetereogeneous catalysis to prevent the sintering of metal nanoparticles (NPs), but issues including restriction supports reducible oxides, nonporous architecture, by thermal treatment at >800 °C, and unstable nature limit their practical application. Herein, construction non-oxide-derived SMSI nanocatalysts based on highly crystalline nanoporous hexagonal boron nitride (h-BN) 2D materials was demonstrated via...
Hydrogen energy has the merits of high value and zero carbon emissions, but its practical application is hindered by intensive input required for dehydrogenation liquid hydrocarbons (170–300 °C). Herein, toward highly efficient saturated N-heterocycles, assembly PdO on vacancy-abundant nitride skeleton derived from in situ Zr-doping was demonstrated to improve catalyst with superior performance under mild conditions. Electron paramagnetic resonance (EPR), electrochemical impedance...
