Repair of dysfunctional bone marrow endothelial cells alleviates aplastic anemia.

Aplastic anemia (AA) is a life-threatening disease characterized by bone marrow (BM) failure and pancytopenia. As an important component of the BM microenvironment, endothelial cells (ECs) play a crucial role in supporting hematopoiesis and regulating immunity. However, whether impaired BM ECs are involved in the occurrence of AA and whether repairing BM ECs could improve hematopoiesis and immune status in AA remain unknown.

Addition of Chelators Increased the Stability of Black Rice Anthocyanins against the Metallic Ions in Tap Water and Improved the Coloration of Steamed Cold Noodles.

The anthocyanins in black rice extract (BRA) are sensitive to metallic ions, which restrict its application in the coloration of steamed cold noodles in China that uses tap water as the solvent. Food-grade chelators were added to check if they could increase the stability of BRA. The results indicated that the color decay of BRA in tap water was mainly caused by Fe, Cu, and Fe, and the addition of chelators could effectively antagonize this effect.

Room-temperature coherent manipulation of single-spin qubits in silicon carbide with a high readout contrast.

Spin defects in silicon carbide (SiC) with mature wafer-scale fabrication and micro/nano-processing technologies have recently drawn considerable attention. Although room-temperature single-spin manipulation of colour centres in SiC has been demonstrated, the typically detected contrast is less than 2[Formula: see text], and the photon count rate is also low. Here, we present the coherent manipulation of single divacancy spins in 4H-SiC with a high readout contrast ([Formula: see text]) and a high photon count rate (150 kilo counts per second) under ambient conditions, which are competitive with the nitrogen-vacancy centres in diamond.

Coherent Control of Nitrogen-Vacancy Center Spins in Silicon Carbide at Room Temperature.

Solid-state color centers with manipulatable spin qubits and telecom-ranged fluorescence are ideal platforms for quantum communications and distributed quantum computations. In this work, we coherently control the nitrogen-vacancy (NV) center spins in silicon carbide at room temperature, in which telecom-wavelength emission is detected. We increase the NV concentration sixfold through optimization of implantation conditions.

Hard Carbon Nanosheets with Uniform Ultramicropores and Accessible Functional Groups Showing High Realistic Capacity and Superior Rate Performance for Sodium-Ion Storage.

Hard carbon attracts considerable attention as an anode material for sodium-ion batteries; however, their poor rate capability and low realistic capacity have motivated intense research effort toward exploiting nanostructured carbons in order to boost their comprehensive performance. Ultramicropores are considered essential for attaining high-rate capacity as well as initial Coulombic efficiency by allowing the rapid diffusion of Na and inhibiting the contact of the electrolyte with the inner carbon surfaces. Herein, hard carbon nanosheets with centralized ultramicropores (≈0.

Color centers in silicon carbide have recently attracted broad interest as high bright single photon sources and defect spins with long coherence time at room temperature. There have been several methods to generate silicon vacancy defects with excellent spin properties in silicon carbide, such as electron irradiation and ion implantation. However, little is known about the depth distribution and nanoscale depth control of the shallow defects.

Impact of fertilization on ammonia volatilization and NO emissions in an open vegetable field.

A field experiment with different nitrogen fertilization rates and mitigation measures was conducted in an open-ground vegetable field on the North China Plain to investigate the effects of nitrogen application level and management practices on ammonia volatilization and NO emission.

Hard@Soft Integrated Morning Glory Like Porous Carbon as a Cathode for a High-Energy Lithium Ion Capacitor.

A lithium ion capacitor (LIC) is a hybrid energy storage device that combines the energy storage mechanism of lithium ion batteries and supercapacitors and presents their complementary features. However, imbalances of the capacity and kinetics between cathode and anode still remain challenges. Herein, to address the issue of low capacity in the cathode, we constructed a morning glory like porous material crimped from an opening sandwich structure consisting of a hard carbon inner layer and soft carbon outer layer, by coating graphene oxide containing flaky phenolic resin with coal tar pitch followed by carbonization and activation.

First assessment of interferon gamma release assay results among healthcare workers at a general hospital in China.

Introduction: China has a very high tuberculosis (TB) burden. The interferon-gamma release assay (IGRA) is more specific for the diagnosis of latent tuberculosis infection (LTBI) than the tuberculin skin test, especially among populations with a high degree of coverage by the BCG vaccine.

Polyacrylonitrile-Derived Sponge-Like Micro/Macroporous Carbon for Selective CO Separation.

CO capture under a dynamical flow situation requires adsorbents possessing balanced proportion of macropores as diffusion path and micropores as adsorption reservoir. However, the construction of interconnected micro-/macropores structure coupled with abundant nitrogen species into one carbon skeleton remains a challenge. Here, we report a new approach to prepare sponge-like carbon with a well-developed micro-/macroporous structure and enriched nitrogen species through aqueous phase polymerization of acrylonitrile in the presence of graphene oxide.
