Ligand-tuning copper in coordination polymers for efficient electrochemical C-C coupling.

Cu catalyses electrochemical CO reduction to valuable multicarbon products but understanding the structure-function relationship has remained elusive due to the active Cu sites being heterogenized and under dynamic re-construction during electrolysis. We herein coordinate Cu with six phenyl-1H-1,2,3-triazole derivatives to form stable coordination polymer catalysts with homogenized, single-site Cu active sites. Electronic structure modelling, X-ray absorption spectroscopy, and ultraviolet-visible spectroscopy show a widely tuneable Cu electronics by modulating the highest occupied molecular orbital energy of ligands.

ITO-Induced Nonlinear Optical Response Enhancement of Titanium Nitride Thin Films.

A series of TiN/ITO composite films with various thickness of ITO buffer layer were fabricated in this study. The enhancement of optical properties was realized in the composite thin films. The absorption spectra showed that absorption intensity in the near-infrared region was obviously enhanced with the increase of ITO thickness due to the coupling of surface plasma between TiN and ITO.

Weight loss, glycolipid profile changes in type 2 diabetes patients after esophagectomy: a propensity score matching analysis.

Background: Type 2 diabetes mellitus (T2DM) is a common co-morbidity in patients who receive esophagectomy and has unfavorable effects on glucose and lipid metabolism in patients. This study examines how weight and glycolipid metabolism change in patients with T2DM following esophagectomy.

Methods: This retrospective, one-center, observational analysis with a propensity score matching analysis (PSM) included 114 patients who underwent esophageal surgery in the Department of Cardiothoracic Surgery, the 900th Hospital of Joint Logistic Support Force from 2017 to 2020, which were separated into T2DM group and Non-T2DM group.

Effect of oesophagectomy on lipid profiles in patients with oesophageal cancer combined with hyperlipidaemia: a retrospective study.

Background: Surgery is widely regarded as a pivotal therapeutic approach for treating oesophageal cancer, and clinical observations have revealed that many oesophageal cancer patients also present with concomitant hyperlipidaemia. It is surprising that few studies have been performed to determine how blood lipid levels are affected by oesophageal cancer resection. This research was designed to assess the influence of oesophageal cancer resection on lipid profiles among individuals diagnosed with both oesophageal cancer and hyperlipidaemia.

Universal Strategy of Efficient Intracellular Macromolecule Directional Delivery Using Photothermal Pump Patch.

The development of a highly efficient, nondestructive, and in vitro/vivo-applicable universal delivery strategy of therapeutic macromolecules into desired cells and tissues is very challenging. Photothermal methods have advantages in intracellular delivery, particularly in in vivo manipulation. However, the inability of directional transmission of exogenous molecules limits their delivery efficiency.

Diclofenac degradation by activating peroxydisulfate via well-dispersed GO/CuO nano-composite.

Owing to high treatment efficiency under neutral condition and no extra energy required, copper-mediated activation of persulfate (PS) has been widely used for the degradation of refractory organic pollutants in water. The dispersion stability of copper nanoparticle in water, however, remains a great challenge. Meanwhile, chemical oxidative modification of graphene oxide (GO) can improve the dispersion stability of GO in water.

BiOI/g-CN Heterostructures With Enhanced Visible-Light Photocatalytic Performance for Degradation of Tetracycline Hydrochloride.

BiOI/g-CN p-n junctioned photocatalysts were synthesized by alcohol-heating and calcination in air. The structures, morphologies and optical properties of as-prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectroscopy (DRS). Photocatalytic activity of the heterojunctioned composites were evaluated by degradation of Rhodamine B (RhB) and tetracycline hydrochloride (TCH) under visible light illumination.

Diclofenac degradation based on shape-controlled cuprous oxide nanoparticles prepared by using ionic liquid.

Persulfate oxidation technology is widely used in wastewater treatment, but there are still many disadvantages, such as high energy consumption, side reaction and narrow pH applicability. Copper oxides can activate persulfate steadily with higher efficiency. In this paper, a novel preparation method of shape-controlled cuprous oxide (CuO) nanoparticles featured with high catalytic performance was explored.

Vascular cell responses to silicone surfaces grafted with heparin-like polymers: surface chemical composition topographic patterning.

Heparin-like polymers are promising synthetic materials with biological functionalities, such as anticoagulant ability, growth factor binding to regulate cellular functions, and inflammation mediation, similar to heparin. The biocompatibility of heparin-like polymers with well-defined chemical structures has inspired many researchers to design heparin-like surfaces to explore their biological applications. The concept of the recombination of functional heparin structural units (sulfonate- and glyco-containing units) was proven to be successful in designing heparin-mimicking surfaces.

Nitric Oxide-Generating Antiplatelet Polyurethane Surfaces with Multiple Additional Biofunctions via Cyclodextrin-Based Host-Guest Interactions.

A nitric oxide-generating polymeric coating was prepared by copolymerization of the hydrophilic monomer 2-hydroxyethyl methacrylate (HEMA) and the comonomer 1-adamantan-1-ylmethyl methacrylate (AdaMA) with subsequent incorporation of selenocystamine. The coating was applied to polyurethane (PU) as a substrate. In the presence of a NO donor, the PU-PHA-Se surface generated nitric oxide (NO).

[Heavy metal pollution characteristics and ecological risk analysis for soil around Haining electroplating industrial park].

The pollution status and potential ecological risks of heavy metal in soils around Haining electroplating industrial park were studied. Hakanson index approach was used to assess the ecological hazards of heavy metals in soils. Results showed that average concentrations of six heavy metals (Cu, Ni, Pb, Zn, Cd and Cr) in the soils were lower than the secondary criteria of environmental quality standard for soils, indicating limited harmful effects on the plants and the environment in general.
