Optoelectronic Devices for In‐Sensor Computing
The raw data obtained directly from sensors in the noisy analogue domain is often unstructured, which lacks a predefined format or organization and does not conform to a specific data model. Optoelectronic devices for in‐sensor visual processing can integrate perception, memory, and processing functions in the same physical units, which can compress ...

As defect density in 3D perovskites is controlled by adjusting excess formamidinium iodide concentration, shallow defects acts as a carrier sink for amplified spontaneous emission (ASE). A comprehensive charge carrier dynamic model is presented to understand the critical factor of the reduction of ASE threshold.

Reprogrammable Mechanical Metamaterials via Passive and Active Magnetic Interactions
The combination of flexible matrices with embedded hard‐magnetic nodes enables metastructures with reprogrammable mechanical properties, even in the absence of external magnetic fields. The evolving interaction between nodes during structural deformation allows mechanical tunability under quasi‐static and dynamic loading, and bistable transitions. This

A Bio‐Inspired Perspective on Materials Sustainability
This perspective discusses natural materials as inspiration for sustainable engineering designs and the processing of materials. First, circularity, longevity, parsimony, and activity are presented as essential material paradigms. The perspective then uses many examples of natural and technical materials to introduce principles such as oligo ...

Ultrafast Laser Synthesis of Zeolites
The study presents a novel ultrafast laser‐driven synthesis technique for zeolites directly in liquid. Laser pulses create a microscopic reactor that controls reaction kinetics at femto‐ and picosecond timescales. Nonlinear light‐matter interactions drive nucleation and growth, allowing the process to be paused at any stage of self‐assembly.
