15We provide the first evidence that an EndMT occurs in RIPF development and that the EndMT may be effectively inhibited by modulating vascular EC-specific hypoxic damage.
Three-dimensional (3D) carbon nitride (C3 N4 )-based materials show excellent performance in a wide range of applications because of their suitable band structures. To realize the great promise of two-dimensional (2D) allotropes of various 3D materials, it is highly important to develop routes for the production of 2D C3 N4 materials, which are one-atom thick, in order to understand their intrinsic properties and identify their possible applications. In this work, water-dispersible, atomically t
Raman spectra of single-wall carbon nanotubes (SWNTs) exhibit a unique radial breathing mode (RBM) band (∼100–300 cm–1) and a G– peak (∼1570 cm–1), along with a D band (∼1350 cm–1). We show that the typical Raman signals for SWNTs are the signature of their helical structure determined using density functional theory simulation and structural analysis for hydrogenated and dehydrogenated SWNT samples. We demonstrate that the G– mode at ∼1570 cm–1 is unique to opened tubular graphene structures of
In this work, we present the fabrication and characterization of a 2-chloroethyl ethyl sulfide (2-CEES) gas sensor based on ZnO nanoparticles (NPs) synthesized by a hydrothermal method. We confirmed that synthesized ZnO NPs adopt a polycrystalline phase. Partially aggregated ZnO-NPs revealed spherical or ellipsoidal nanocrystalline particles in a size range of 30-50 nm, as observed by field-emission scanning electron microscopy (FE-SEM). The maximum response of the ZnO NPs was 15 at 1 ppm 2-CEES
N-containing gaseous compounds, such as trimethylamine (TMA), triethylamine (TEA), ammonia (NH<sub>3</sub>), nitrogen monoxide (NO), and nitrogen dioxide (NO<sub>2</sub>) exude irritating odors and are harmful to the human respiratory system at high concentrations. In this study, we investigated the sensing responses of five sensor materials-Al-doped ZnO (AZO) nanoparticles (NPs), Pt-loaded AZO NPs, a Pt-loaded WO<sub>3</sub> (Pt-WO<sub>3</sub>) thin film, an Au-loaded WO<sub>3</sub> (Au-WO<sub>
