Synaptic memristors based on BaTiO thin films irradiated by swift heavy ions for neuromorphic computing.

Swift heavy ion (SHI) irradiation is an effective method for modulating the properties of thin oxide films by introducing defects, strains, and structural transformations. Here, we applied 516 MeV Xe irradiation to BaTiO (BTO) thin films grown on Nb:SrTiO substrates to induce the generation of tracks and nanohillocks. Memristors with BTO films irradiated at a fluence of 5 × 10 ions cm displayed excellent retention and endurance characteristics.

Highly Enhancing CO Photoreduction by Metallization of an Imidazole-linked Robust Covalent Organic Framework.

Converting CO into value-added chemicals to solve the issues caused by carbon emission is promising but challenging. Herein, by embedding metal ions (Co , Ni , Cu , and Zn ) into an imidazole-linked robust photosensitive covalent organic framework (PyPor-COF), effective photocatalysts for CO conversion are rationally designed and constructed. Characterizations display that all of the metallized PyPor-COFs (M-PyPor-COFs) display remarkably high enhancement in their photochemical properties.

From Supramolecular Organic Cages to Porous Covalent Organic Frameworks for Enhancing Iodine Adsorption Capability by Fully Exposed Nitrogen-Rich Sites.

In order to overcome the limitations of supramolecular organic cages for their incomplete accessibility of active sites in the solid state and uneasy recyclability in liquid solution, herein a nitrogen-rich organic cage is rationally linked into framework systems and four isoreticular covalent organic frameworks (COFs), that is, Cage-TFB-COF, Cage-NTBA-COF, Cage-TFPB-COF, and Cage-TFPT-COF, are successfully synthesized. Structure determination reveals that they are all high-quality crystalline materials derived from the eclipsed packing of related isoreticular two-dimensional frameworks. Since the nitrogen-rich sites usually have a high affinity toward iodine species, iodine adsorption investigations are carried out and the results show that all of them display an enhancement in iodine adsorption capacities.

Objective: To explore the effectiveness of multidisciplinary intervention for patients with gestational diabetes mellitus (GDM).

Methods: A total of 126 patients diagnosed with GDM from January 2020 to December 2021 in our hospital were enrolled in this retrospective study. Patients were divided into the control group (conventional treatment) and the study group (adding multidisciplinary intervention).

Endobiliary Ablation Combined with Immune Nutrition Improves Quality of Life: A Preliminary Clinical Study in Patients with Advanced Malignant Obstructive Jaundice.

BACKGROUND In patients with advanced malignant obstructive jaundice (MOJ), it remains an intractable problem to maintain biliary patency, because repeated stent occlusion and poor immune condition can lead to serious infection. The aim of this study was to investigate the effect of endobiliary ablation combined with immune nutrition (IN) on advanced MOJ. MATERIAL AND METHODS A prospective randomized pilot study of patients undergoing percutaneous transhepatic biliary drainage (PTBD) for advanced MOJ was conducted.

Facile construction of a highly proton-conductive matrix-mixed membrane based on a -SOH functionalized polyamide.

Developing a facile strategy to construct low-cost and efficient proton-conductive electrolytes is pivotal in the practical application of proton exchange membrane (PEM) fuel cells. Herein, a polyamide with in-built -SOH moieties, PA(PhSO3H)2, was synthesized a simple one-pot polymeric acylation process. Investigations electrochemical impedance spectroscopy (EIS) measurements revealed that the fabricated PA(PhSO3H)2 displays a proton conductivity of up to 5.

Influence of Ultraviolet and Oxygen Coupling Aging on Rheological Properties and Functional Group Index of Warm Mix Asphalt Binder.

Warm-mixed asphalt (WMA) has the characteristics of low mixing temperature and energy consumption, which makes it more suitable than hot-mixed asphalt for plateau regions (the altitude is above 500 m, and the terrain is relatively flat or has a wide area with certain undulations). However, WMA is subject to severe ultraviolet (UV) aging because the UV radiation in plateau areas is more intense. The asphalt's aging changes its rheological properties inevitably, and thus degrades the asphalt pavement's performance.

Efficient Ce-Co composite oxide decorated Au nanoparticles for catalytic oxidation of CO in the simulated atmosphere of a CO laser.

Gold nanoparticles have a high activity for CO oxidation, making them suitable to be used in a CO laser which maintains its efficiency and stability the recombination of CO and O produced by the CO decomposition. However, the high concentration of CO in the working environment greatly reduces the activity of the catalyst and makes the already unstable gold nanoparticles even more so. A novel Au/Ce-Co-O /AlO gold catalyst, prepared by a deposition precipitation method in this study, displays high activity and good stability for CO oxidation in a simulated atmosphere of a CO laser with the feed gases containing a high concentration of CO up to 60 vol% but a low concentration of O for the stoichiometric reaction with CO.

Research on Design and Simulation of Biaxial Tensile-Bending Complex Mechanical Performance Test Apparatus.

In order to realize a micro-mechanic performance test of biaxial tensile-bending-combined loading and solve the problem of incompatibility of test apparatus and observation apparatus, novel biaxial-combined tensile-bending micro-mechanical performance test apparatus was designed. The working principle and major functions of key constituent parts of test apparatus, including the servo drive unit, clamping unit and test system, were introduced. Based on the finite element method, biaxial tensile and tension-bending-combined mechanical performances of the test-piece were studied as guidance to learn the distribution of elastic deformation and plastic deformation of all sites of the test-piece and to better plan test regions.

Deformation behavior of micro-indentation defects under uniaxial and biaxial loads.

The microdefects of structure frequently act as the source to generate initial cracks and lead to the fracture failure. Study on the deformation behaviors of embedded defects would be conducive to better understand the failure mechanisms of structural materials. Micro-indentation technique was applied to prepare the initial indentations as embedded surface defects at the gauge length section and central section of a cross-shaped AZ31B magnesium alloy specimen.

An Open-Framework Germanate with Polycubane-Like Topology.

Body-centered Ge parallelepiped building blocks form the basis of the structure of [Ge O (OH) ]⋅2 (H ppz)⋅0.5 (H O) (ASU-14, ppz=piperazine). In this new structure type for an open-framework germanate (see picture for a section of the structure) the building blocks are linked together at each of their eight vertices to give the rare polycubane topology with an intersecting channel system of ten- and eight-membered rings (pore sizes 5×6 and 4×4 Å , respectively) in which the piperazinium cations and water molecules reside.
