Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Bath Vibration During Open Eye Formation in a Physical Model of a Steelmaking Ladle

steel research international, EarlyView.
Using a physical model, this study shows that vibration measurements reliably predict open eye size in steelmaking ladles, offering a practical alternative to visual monitoring. Vessel vibrations stabilize faster than the open eye, except at high frequencies near the bottom.

Pressure Pulses Generated by Wire‐Guided Discharges in Water

High Voltage, EarlyView.
ABSTRACT The hydrodynamic characteristics of underwater wire‐guided discharges and their relationships with the wire length and pulsed circuit parameters are not fully understood. In this paper wire‐guided discharges using wires of length 3, 5 and 7 cm and diameter of 0.05 mm have been investigated. The energy available to the discharges was 162.3 J at

Dynamic Modal‐Based Vibration Characteristics Analysis and Looseness Fault Diagnosis in Transformer Winding

High Voltage, EarlyView.
ABSTRACT Limited by the theoretical basis and diagnostic methods, the winding mechanical condition monitoring often requires both normal condition vibration signals and present vibration signals, and the winding mechanical condition identification is completed by comparing with the normal condition signals.

mcstas_gisans: combining ray tracing with the distorted‐wave Born approximation using McStas and BornAgain for virtual GISANS experiments

Journal of Applied Crystallography, EarlyView.
mcstas_gisans is a Python‐based framework that enables simulation of grazing‐incidence small‐angle neutron scattering experiments by integrating McStas and BornAgain into a single workflow.The mcstas_gisans framework is a collection of Python scripts and modules to facilitate the simulation of grazing‐incidence small‐angle neutron scattering (GISANS ...
