Improving High‐Temperature Operational Stability of Inverted Perovskite Solar Cells Through MXene Heat‐Dissipating Layers

Advanced Science, EarlyView.
MeO‐2PACz‐functionalized MXene nanosheets create a thermally conductive buried interface in inverted perovskite solar cells. The interface improves heat spreading, suppresses defects and ion migration, and strengthens charge extraction, extending T80 at 65°C from 141 to 687 h while maintaining competitive efficiency.

Establishment of Safety Evaluation Factors for Dust Storms in the Landing Area Selection for Tianwen‐3 Mission

Earth and Space Science
China's Tianwen‐3 mission is expected to be launched around 2028, making it the first Mars sample return mission. Dust storms occurring in all seasons on Mars can affect the accuracy and safety of the landing and takeoff phases of Mars sampling missions.

Generative AI‐Enabled Discovery and Experimental Demonstration of Ultra‐Broadband Epsilon‐Near‐Zero Perfect Absorbers

Advanced Science, EarlyView.
Researchers developed and applied a generative artificial intelligence (AI) model to optimize epsilon‐near‐zero thin film stacks for ultra‐broadband perfect absorption of light. The fabricated AI‐designed absorber, with a total thickness of only 160 nm, experimentally demonstrated an absorption bandwidth exceeding 1000 nm while maintaining greater than

Covalently Locked Donor–Acceptor Block Copolymer Nanoparticles Enable Efficient, Stable and Reproducible Photocatalytic Hydrogen Evolution

Advanced Energy Materials, EarlyView.
To overcome the efficiency–stability trade‐off of traditional donor:acceptor blends, covalently locked all‐conjugated block copolymer nanoparticles are developed for solar hydrogen production. This strategy achieves an outstanding HER rate exceeding 120 mmol cm−2 g−1 h−1, alongside exceptional operational stability (95% retention after 96 h) and high ...

W.N. Christiansen and the development of the solar grating array [PDF]

, 2008
By 1950 the C.S.I.R.O’s Division of Radiophysics was emerging as a leader in solar radio astronomy. Early observations at radio frequencies were hampered by a lack of angular resolution.

Ice‐Droplet and Damaged Elastomer Interfaces: A Closer Look at Contact and Morphology of Anti‐Icing Coatings Using Cryo‐FIB‐SEM

Journal of Applied Polymer Science, EarlyView.
Cryo‐FIB‐SEM is used to mill and image the interfaces of ice droplets frozen on PDMS coatings damaged by abrasion and cutting. Both high‐ and low‐real contact areas are revealed for the first time, with interpenetration dependent on the shape of asperities on the damaged surface.
