Multi-dimensional optical information acquisition based on a misaligned unipolar barrier photodetector

Nature Communications
Acquiring multi-dimensional optical information, such as intensity, spectrum, polarization, and phase, can significantly enhance the performance of photodetectors.

Fracton Infrared Triangle

Physical Review Letters
In theories with conserved dipole moment, isolated charged particles (fractons) are immobile, but dipoles can move. We couple these dipoles to the fracton gauge theory and analyze the universal infrared structure. This uncovers an observable double kick memory effect which we relate to a novel dipole soft theorem.

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

Advanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

ON INFRARED DIVERGENCES

Nuclear Physics B, 1979
Revised 25 September 1978 We study the structure of infrared divergences in superrenormalizable interactions. We conjecture that there is an extension of the Bogoliubov-Parasiuk-Hepp theorem which copes also with infrared divergences. We discuss the consequences of this conjecture on the singularities of the Borel transform in a massless asymptotic ...

Electroactive Metal–Organic Frameworks for Electrocatalysis

Advanced Functional Materials, EarlyView.
Electrocatalysis is crucial in sustainable energy conversion as it enables efficient chemical transformations. The review discusses how metal–organic frameworks can revolutionize this field by offering tailorable structures and active site tunability, enabling efficient and selective electrocatalytic processes.
