Hometronics: Accessible production of graphene suspensions for health sensing applications using only household items
Adel K. A. Aljarid, Jasper Winder, Cencen Wei +6
Nanoscience at times can seem out of reach to the developing world and the general public, with much of the equipment expensive and knowledge seemingly esoteric to nonexperts. Usin…
Understanding Substrate Effects on Two-Dimensional MoS2 Growth: a Kinetic Monte Carlo Approach
Samuel Aldana, Ion Spiridon, Lulin Wang +1
Controlling the morphology of two-dimensional (2D) transition metal dichalcogenides (TMDs) plays a key role in their applications. Although chemical vapor deposition can achieve wa…
Machine Learning Predictions of High-Curie-Temperature Materials
Joshua F. Belot, Valentin Taufour, Stefano Sanvito +1

Exploring anisotropy and diverse magnetization dynamics in specimens with vanishing magnetic moments presents a significant challenge using traditional magnetometry, as the low res…
Combined electronic excitation and knock-on damage in monolayer MoS2
Carsten Speckmann, Julia Lang, Jacob Madsen +7
Electron irradiation-induced damage is often the limiting factor in imaging materials prone to ionization or electronic excitations due to inelastic electron scattering. Quantifyin…
A rule-free workflow for the automated generation of databases from scientific literature
Luke P. J. Gilligan, Matteo Cobelli, Valentin Taufour +1
In recent times, transformer networks have achieved state-of-the-art performance in a wide range of natural language processing tasks. Here we present a workflow based on the fine-…
A computational method to estimate spin-orbital interaction strength in solid state systems
Qiangqiang Gu, Shishir Kumar Pandey
Spin-orbit coupling (SOC) drives interesting and non-trivial phenomena in solid state physics, ranging from topological to magnetic to transport properties. Thorough study of such…
Strain-induced stacking transition in bilayer graphene
