An undulator is a device which is widely used in the modern synchrotron light sources to produce quasi-monochromatic light. The waveform of the electric-field produced by an relativistic electron in the undulator is basically defined by the number of magnets and the gap between the magnets in the undulator. The square shaped waveform is predicted by a simple electro-magnetic theory, however, it has never been measured because no method has been suggested. It is important to characterize the electric-field produced in the undulator for the development of syn-chrotron sources.

JSNS $$^2$$ (J-PARC Sterile Neutrino Search at J-PARC Spallation Neutron Source) is an experiment that searches for sterile neutrinos via the observation of $$\bar{\nu }_{\mu } \rightarrow \bar{\nu }_{e}$$ appearance oscillations using muon decay-at-rest neutrinos. The JSNS $$^2$$ experiment performed data taking from 2021. In this manuscript, a study of the accidental background is presented. The rate of the accidental background is ( $$9.29\pm 0.39) \times 10^{-8}$$ /spill with 0.75 MW beam power and comparable to the expected number of signal events.

In this study, we investigate the numerical stability of the covariant BSSN (cBSSN) formulation proposed by Brown. We calculate the constraint amplification factor (CAF), which is an eigenvalue of the coefficient matrix of the evolution equations of the constraints on the cBSSN formulation and on some adjusted formulations with constraints added to the evolution equations. The adjusted formulations have a higher numerical stability than the cBSSN formulation from the viewpoint of the CAF. Copyright © 2022, The Authors. All rights reserved.

Heterostructured Zr-Ni4Mo/Mo2N nanorod with lattice expansion induced by Zr doping for efficient and durable hydrogen evolution reaction

Non-precious metal electrocatalysts with high activity for hydrogen evolution reaction (HER) is important for decreasing the energy consumption of hydrogen production and the cost of water electrolysis devices. However, the existing highly active electrocatalysts generally suffer from oxidation and deactivation under harsh conditions of industrial water splitting. Herein, a heterostructured Zr-Ni4Mo/Mo2N nanorod material with lattice expansion induced by Zr doping is fabricated as an efficient and durable electrocatalyst for HER. The prepared Zr-Ni4Mo/Mo2N exhibits ultra-low overpotential of only 8 mV at 10 mA cm−2 in 1 M KOH. Particularly, the electrolytic cell equipped with Zr-Ni4Mo/Mo2N cathode consumes a low voltage of only 1.585 V under industrial alkaline water electrolysis conditions (3000 A m−2, 80 °C, 30 wt% KOH). The exceptionally high catalytic activity of Zr-Ni4Mo/Mo2N is proved by the low activation energy (Eaη=0) of 18.19 kJ mol−1. The lattice expansion and heterointerfaces generate abundant catalytic active sites. Moreover, Zr doping not only regulates electronic structure of Zr-Ni4Mo/Mo2N and reduces the kinetic energy barrier of HER, but also prevents the oxidation of active sites, which endows the Zr-Ni4Mo/Mo2N with excellent activity and strong durability. This work provides a new avenue for the design of non-precious metal electrocatalysts, which exhibit a promising prospect in industrial water splitting. © 2025 Elsevier B.V.

Heavy metals pose a significant threat to human health and the environment due to their toxicity and persistence. We have fabricated electrospun nanofibers with poly(ε-caprolactone) (PCL) and chitosan (CS), incorporating hematite nanoparticles (HNPs) and used to remove Cr⁶⁺ and Cs⁺ from simulated solutions. The nanofibers were characterized by various techniques and adsorption studies investigated the impact of pH, adsorbent dosage, initial contaminant concentration, and contact time on the removal efficiency of Cr⁶⁺ and Cs⁺. SEM and EDS analyses confirmed the adsorption of both contaminants onto the nanofibers. The maximum adsorption for Cr⁶⁺ was achieved under acidic conditions, while Cs⁺ adsorption was favoured in alkaline environments. Isotherm studies demonstrated that the adsorption process followed both Langmuir and Freundlich models. Additionally, pseudo-kinetic studies indicated that the adsorption mechanism adhered to a second-order kinetic model. The ability of these nanofibers to effectively remove heavy metals from water solutions highlights their potential for environmental remediation applications. © 2025 Elsevier B.V.

The SliT ASIC is a readout chip for the silicon strip detector to be used at the J-PARC muon g−2/EDM experiment. The production version of SliT128D was designed and mass production was finished. A quality assurance test method for bare SliT128D chips was developed to provide a sufficient number of chips for the experiment. The quality assurance test of the SliT128D chips was performed and 5735 chips were inspected. No defect was observed in chips of 84.3%. Accepting a few channels with poor time walk performance out of 128 channels per chip, more than 90% yield can be achieved, which is sufficient to construct the whole detector. © 2024, CC BY-NC-ND.

Phytochemical investigation of the leaf extract of Uvaria grandiflora Roxb. ex Hornem led to the isolation and identification of two new highly oxygenated cyclohexenes, uvariagrandols A (1) and B (2), together with seven known compounds (3–9). Their structures were elucidated by spectroscopic methods as well as comparisons made from the literature. The (1S,2S,3R,6S) absolute configuration of uvariagrandols A and B was established by the comparison of the experimental and calculated electronic circular dichroism (ECD). (+)-Grandifloracin (9) displayed cytotoxicity against SW480 and K562 cell lines with IC₅₀ values of 154.9 and 60.9 μM, respectively. 6-Methoxyzeylenol (5) had α-glucosidase inhibitory activity with the IC₅₀ value of 34.1 μM. © 2024 The Authors
