Quantitative prediction of grain boundary thermal conductivities from local atomic environments

Nature Communications, 2020
Connecting grain boundary structures to macroscopic thermal behaviour is an important step in materials analysis and design. Here the authors develop a physical model combined with a machine-learning approach to accurately predict thermal conductivities ...

Ultrafast high-harmonic nanoscopy of magnetization dynamics

Nature Communications, 2021
Light induced magnetization dynamics can be as fast as few tens of femtoseconds. Here, Zayko et al show ultrafast microscopy based on high-harmonic radiation for direct imaging of ultrafast phenomena and capture femtosecond spin dynamics at the nanoscale.

Microscopic mechanism of biphasic interface relaxation in lithium iron phosphate after delithiation

Nature Communications, 2018
Improving the performance of Li-ion batteries relies on understanding charging/discharging mechanisms. Here the authors visualize the interfacial structure and composition of a partially delithiated lithium iron phosphate single crystal as a function of ...

Neutron Scattering as a Powerful Tool to Investigate Magnetic Shape Memory Alloys: A Review

Metals, 2021
Magnetic shape memory alloys (MSMAs) are an interesting class of smart materials characterized by undergoing macroscopic deformations upon the application of a pertinent stimulus: temperature, stress and/or external magnetic fields. Since the deformation

A mid-infrared lab-on-a-chip for dynamic reaction monitoring

Nature Communications, 2022
Rapid investigation of chemical reactions is a challenge in bio-medical analysis. Here, the authors demonstrate sensitive in-situ real-time reaction-monitoring of conformational changes in protein solution, based on a fingertip-sized mid-IR lab-on-a-chip.

Coherent manipulation of a solid-state artificial atom with few photons

Nature Communications, 2016
Quantum information processing requires a system in which a single photon controls a single atom and vice versa. Here, the authors demonstrate such reciprocal operation and achieve coherent manipulation of a quantum dot by a few photons sent on an ...
