Deep Learning-Accelerated Dynamic Kinetic Monte Carlo Simulation for Hydrogen Transport in Tungsten
arXiv:2606.02084v2 Announce Type: replace-cross Abstract: In magnetic confinement fusion reactors, hydrogen plasma irradiation causes material saturation and recycling, where hydrogen released from the tungsten wall significantly impacts the peripheral plasma. Kinetic Monte Carlo (kMC) simulations are essential for investigating the dynamic balance between incident and emitted fluxes at the atomic scale. However, standard kMC frameworks are inadequate for handling realistic material...

China, tungsten and a supply shock in metal critical for war that will last far beyond Iran conflict
The Iran war has caused well-documented price spikes and shortages on a range of items Americans depend upon. Oil and gas, of course, but also petrochemicals and everything derived from them (e.g. plastics) and helium are among raw materials that have been besieged by the closure of the Strait of Hormuz. Still, there is another element which has seen its price surge amid increasingly short supply because of war, but where the shock will not relent even if the Strait is reopened.
Development of a 3D-CNN-based Prediction Model for Migration Barriers in Plasma-Wall Interactions
arXiv:2604.05521v2 Announce Type: replace Abstract: Understanding the long-term transport of hydrogen isotopes in plasma-facing materials, such as tungsten, is critical for the steady-state operation of magnetic confinement fusion reactors. However, dynamically updating the transition parameters for kinetic Monte Carlo (kMC) simulations as the atomic structure evolves under continuous plasma irradiation remains a severe computational bottleneck. Conventionally, calculating these migration...
Race for rare earths at Myanmar’s borders fuels pollution fears
Race for rare earths at Myanmar’s borders fuels pollution fears Russian and Chinese firms are also competing to be the first to reach a tungsten mine in a conflict zone, sparking concerns of NGOs Myanmar is among the top three producing nations of rare earths and other critical minerals used to make magnets and other components that power products ranging from smartphones to electric vehicles, with most of its output exported to neighbouring China, where it is refined. Rare earths and metals...
Manufacturability studies for the FCC-ee positron source target: determination of the minimum bending radius and ovalization in tantalum cooling tube elbows
new Abstract: Beam intercepting devices rely on cooling systems to effectively dissipate the thermal energy generated during the impact of a high-energy beam. Regardless of the device's size, integrating the cooling system is a complex task, particularly when the resulting device is only a few centimetres in size, as is the case with the positron source target for the Future Circular Collider at CERN, where the current design consists of a tungsten core with two embedded tantalum cooling...
Lighter X-ray aprons could spare health care workers from chronic pain
Lighter X-ray aprons could spare health care workers from chronic pain Sadie Harley Scientific Editor Andrew Zinin Lead Editor A light, flexible polymer material developed at the University of Waterloo could replace the lead in heavy X-ray aprons, providing the same protection from harmful radiation while reducing their weight by almost 90%. "For patients who only get X-rays once in a while, heavy lead aprons might be OK, but technicians who wear them every day often develop back and neck...

Photoexcitation flips 2D moiré devices from metals to insulators in ultrafast test
June 4, 2026 feature Photoexcitation flips 2D moiré devices from metals to insulators in ultrafast test Ingrid Fadelli Author Sadie Harley Scientific Editor Robert Egan Associate Editor Quantum materials, materials with properties that are governed by the laws of quantum mechanics describing many-body interactions, have proved promising for the development of various advanced technologies. Many of these materials undergo so-called phase transitions, switching between different physical...
Why China keeps North Korea's economy alive
Why China keeps North Korea's economy alive June 1, 2026North Korea runs one of the most bizarre economies on the planet. Despite being one of only a handful of nations with nuclear weapons, its 2024 gross domestic product (GDP) was a paltry $26.6 billion (€22.9 billion). This is about 70 times smaller than South Korea's $1.86 trillion economy and about a fifth of the annual revenue of the world's top-traded company, NVIDIA.
