Recent Advances in Wide‐Bandgap Perovskite Solar Cells
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

Star-planet magnetic interaction and evaporation of planetary atmospheres [PDF]
Stars interact with their close-in planets through radiation, gravitation, and magnetic fields. We investigate the energy input to a planetary atmosphere by reconnection between stellar and planetary magnetic fields and compare it to the energy input of ...

Characterization of Planetary Atmospheres
After the discovery of the first exoplanet in 1990’s and a fast growing number of discoveries since then, there have been many attempts to observe and characterize their atmospheres. In particular, water and methane have been the focus of many investigations due to their relevance to the origin of life and habitability, as well as their major roles to ...

Mechanochromic hydroxypropyl cellulose (HPC) integrated with microfluidic devices creates scalable, eco‐friendly reflective color displays. We demonstrate mechanochromic displays with 500 µm pixel size and 5Hz switching rates with room for optimisation. The proposed mechanochromic HPC displays are an initial step toward more environmentally responsible

Electric Field Driven Soft Morphing Matter
This study presents soft morphing matter robots that exhibit extremely high morphological adaptability and complex multimodal electric field response. They can undergo large, controlled body deformation and show complex locomotion on different terrains under the manipulation of external electric fields, making a significant step beyond current ...

The larger ion size of Na+ versus with Li+ has a pronounced impact on the intercalation chemistry of disordered rocksalt cathode materials. On charge, the disordered rocksalt structure is retained in Li2MnO2F but it is lost in Na2MnO2F resulting in extensive amorphization.

Ancestral Protein‐Based Lighting
The ancestral sequence reconstruction (ASR) method applied to a large dataset of modern fluorescent proteins (FPs) led to a bright ancestral‐like FP suitable for photon down‐conversion in bio‐hybrid light‐emitting diodes (Bio‐HLEDs). Abstract Protein‐optoelectronics is a paradigm toward eco‐designed and sustainable technologies.

Liquid Metal‐Vitrimer Conductive Composite for Recyclable and Resilient Electronics
To address the growing electronic waste challenge, an electrically conductive, healable, and recyclable plastic composite is created, composed of vitrimer and liquid metal microdroplets. A reconfigurable circuit board is demonstrated using this composite material, providing a notable step toward sustainable and robust electronic technologies.
