Unveiling how heat moves in materials with atomic-scale resolution
Researchers developed and implemented monochromated electron energy-loss spectroscopic methods in a transmission electron microscope to map lattice vibrations (phonons) at atomic resolution, enabling deeper understanding of the way heat travels through nanostructured quantum dot superlattices.
Chemical imaging more than just surface deep
Researchers at Helmholtz-Zentrum Berlin für Materialien und Energie developed a new spectromicroscopy method that significantly improves the study of chemical reactions on the nanoscale, both on surfaces and inside layered materials. They used the method to investigate the adsorption and intercalation of chemical species on MXene electrodes.
ENERGY
Breakthrough in anode electrode materials for proton-conducting solid oxide fuel cells
Tokyo University of Science researchers developed a new perovskite-based anode material with mixed hole-proton conduction to achieve high efficiency at low and medium temperatures in solid oxide fuel cells.
High-entropy tungsten bronze capacitors set new benchmark for energy storage
Researchers proposed a high-entropy tungsten bronze-type relaxor ferroelectric ceramic with an ultrahigh recoverable energy density of 11.0 J/cm3 and a high efficiency of 81.9%.
MANUFACTURING
A new method to grow materials for the chips of the future
Researchers at the University of Southern California Viterbi School of Engineering devised a novel technique to grow thin chalcogenide films safely and to a high standard. They used a technique called hybrid pulsed laser deposition and harnessed a noncorrosive organosulfur compound as the sulfur source for thin film growth.
Scientists create largest nonlinear photonic crystal to date
Researchers created the largest nonlinear photonic crystal to date out of barium titanate spin coated on a special substrate.

Researchers develop a platform to probe, control qubits in silicon for quantum networks
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences developed a platform based on a simple electric diode to probe, interact with, and control qubits in silicon for quantum networks.
Breakthrough may clear major hurdle for quantum computers
Chalmers University of Technology researchers created a system that enables extremely complex operations on a multistate quantum system at an unprecedented speed. The system is based on so-called continuous-variable quantum computing and uses harmonic oscillators, a type of microscopic component, to encode information linearly.
An alternative way to manipulate quantum states
ETH Zurich researchers showed that quantum states of single electron spins can be controlled by currents of electrons whose spins are evenly aligned. In the future, this method could be used in electronic circuit elements.
