Transition metal phosphides (TMP)-based oxygen evolution reaction (OER) catalysts constructed by interface engineering strategy have a broad prospect due to their low cost and good performance. Herein, a novel CeO2/NiCoP nanoarray with intimate phosphide (NiCoP)-oxide (CeO2) interface was developed via in situ generation on nickel foam (NF). This structure is conducive to increasing active sites and accelerating charge transfer, and may be conducive to regulating electronic structure and adsorption energy. As expected, optimal 1.4-CeO2/NiCoP/NF delivers a low overpotential of 249 mV at the current density of 10 mA cm-2 with a Tafel slope of 77.2 mV dec-1. CeO2/NiCoP/NF boasts one of the best OER catalytic materials among recently reported phosphides (TMP)-based OER catalysts and composite catalysts involving CeO2. This work provides an effective strategy for the construction of hetero-structure with CeO2 with oxygen vacancies to improve the OER performance of phosphides.
This work explored the reliability of using points on the heart sounds envelope as indicators of opening and closure of the aortic valve (AVO, AVC) for measuring the pre-ejection period (PEP) and left ventricular ejection time (LVET).

36 phonocardiograms (PCGs) from healthy and cardiovascular disease subjects were denoised using single-channel independent component analysis (SCICA) and, from the Hilbert envelopes, the positions of the S1 and S2 peaks were detected (pS1, pS2). Complementary, the positions of the local maxima of S1 and S2 (mS1, mS2) and the points surrounding pS1 and pS2 (tS1, tS2) were obtained. Finally, the reliability of these points (and the corresponding PEP and LVET intervals) was evaluated by calculation of three error indexes (ePEP, eLVET and score) and by comparison to reference annotations given by echocardiography, this using the Bland-Altman analysis and the paired T-test.

Results indicated that, from a total of 920 and 341 heartbeats in the healthy and diseased groups, respeced in other studies.The development of renewable energy conversion and storage has triggered the development of electrode materials for oxygen evolution reaction (OER) and supercapacitors. Here we report a highly active Cu doped NiFe nanosheets hydroxide electrode with rich oxygen vacancies (OVs) (denoted as H-NiFeCuO/NF) prepared by in situ anodic electrodeposition on the three-dimensional macroporous nickel foam (NF) substrate followed by heat treatment with H2. The as-prepared H-NiFeCuO/NF electrode showed the initial potential of 1.44 V (versus RHE) for OER and 980 F g-1 specific capacity as supercapacitor in 1 M KOH. Further investigation suggested that the tuning of composition and structure by doping copper ions and creating OVs helped accelerate the electrochemical reactions. This practice provides an efficient approach for the fabrication of heteromultimetallic hydroxide monolithic electrode with high performance in OER or supercapacitor application.In this work, the ferroelectricity of hafnium zirconium oxide (Hf0.5Zr0.5O2, HZO) is enhanced by fluorine (F)-plasma treatment, which is used to fabricate MoS2 negative-capacitance field-effect transistor. Measurements show that the subthreshold swing of the transistor is significantly reduced to 17.8 mV dec-1 over almost four orders of output current, as compared to its counterpart without the F-plasma treatment (37.4 mV dec-1). The involved mechanism is that during the F-plasma treatment, F atoms can be incorporated into the HZO bulk to passive its oxygen vacancies and interface traps, thus forming robust Zr-F and Hf-F bonds. Therefore, the F-plasma-treated HZO film exhibits much less oxygen vacancies than the untreated HZO film, which is beneficial to enhancing the amplification effect on the surface potential of the MoS2 channel during the NC operation.During long-pulse deuterium plasma operating in Experimental Advanced Superconducting Tokamak (EAST), a mixed radiation field will be generated, which is mainly composed of fusion neutrons, gamma rays, x-rays and so on. More accurately and effectively dose monitoring methods were developed and established to obtain the ionizing radiation intensity for the stable operation of the device and personnel radiation safety. As we know, there is few reports about the biological effects of radiation induced by fusion neutrons and γ radiation, which is of vital importance to the assessing radiation hazards from fusion devices such as EAST on human being and ecological environment. In present study, three positions in EAST hall were selected to detect genotoxic effects induced by nuclear fusion radiation using Vicia faba micronucleus test for the first time. The doses of neutrons and gamma rays at these places were measured by thermoluminescence dosimeters for four times from June 2019 to May 2020. The radiation doses were decreased as the distances from EAST device shell gradually increased from S1 to S3. Radiation in EAST hall resulted in a significant induction of micronucleus in Vicia faba root tips cells compared to negative control, which was different from micronucleus frequency indued by fission neutrons, γ-rays and other kind of radiation in previous studies. These results indicated that there has existence of potential genotoxic effects induced by radiation from EAST which was different from other radiation and suggested that it was not allowed to enter the experimental hall during the discharge process, and the radiation protection measures should be taken during the necessary maintenance to avoid radiation damage. These newly acquired results will certainly increase our knowledge on the biological effects induced by radiation from nuclear fusion and provide good data support for developing more effective environmental and personnel fusion radiation protection.In the search of topological superconductors, nailing down the Fermiology of the normal state is as crucial a prerequisite as unraveling the superconducting pairing symmetry. In particular, the number of time-reversal-invariant momenta (TRIM) in the Brillouin zone enclosed by Fermi surfaces is closely linked to the topological class of time-reversal-invariant systems, and can experimentally be investigated. selleckchem We report here a detailed study of de Haas van Alphen quantum oscillations in single crystals of the topological semimetal CaSn3with torque magnetometry in high magnetic fields up to 35 T. In conjunction with density functional theory based calculations, the observed quantum oscillations frequencies indicate that the Fermi surfaces of CaSn3enclose an odd number of TRIM, satisfying one of the proposed criteria to realize topological superconductivity. Nonzero Berry phases extracted from the magnetic oscillations also support the nontrivial topological nature of CaSn3.
