Breaking Optical Transparency and Electromagnetic Performance Trade‐Offs for Transparent Reflective Metasurfaces

Advanced Optical Materials, EarlyView.
A theory‐guided magnetoelectric metasurface design breaks the conventional optical transparency and electromagnetic performance trade‐offs. By preserving the electric and magnetic current paths required for efficient reflection through fine‐metal‐line structure, the developed transparent reflective metasurface achieves high optical transparency without

Kicking the can down the road: understanding the effects of delaying the deployment of stratospheric aerosol injection

Environmental Research: Climate
Climate change is a prevalent threat, and it is unlikely that current mitigation efforts will be enough to avoid unwanted impacts. One potential option to reduce climate change impacts is the use of stratospheric aerosol injection (SAI).

Post‐Deposition Photonic Curing Treatment for Improved Sb2Se3 Photovoltaic Performance

Advanced Optical Materials, EarlyView.
Millisecond‐scale photonic curing overcomes the open‐circuit voltage deficit in Sb2Se3 solar cells by transforming the rear interface. This ultrafast treatment enhances crystallographic texture and smooths the absorber surface, suppressing interfacial recombination and boosting power conversion efficiency to 8.2%.

Cyclodextrin‐Functionalized Light‐Driven Cu2O Micromotors for Simultaneous Capture and Degradation of Bisphenol A

Advanced Robotics Research, EarlyView.
Fuel‐free Cu2O‐based micromotors functionalized with β‐cyclodextrin actively remove bisphenol A from water under visible light. The cyclodextrin shell captures BPA and enhances micromotor motility, leading to faster degradation and higher overall removal than nonfunctionalized Cu2O and Cu2O@Au.

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

Advanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Solar radiation modification: SAPEA evidence review report

In August 2023, the College of Commissioners asked the Group of Chief Scientific Advisors to produce a Scientific Opinion on the complex issue of solar radiation modification (SRM). The aim is for the Advisors' policy recommendations to contribute to defining the EU's position in international discussions on SRM, as well as informing any future ...
