Wide angle search for extrasolar planets by the transit method [PDF]
, 2008 The transit method is considered to be one of the most promising for discovering extrasolar planets. However, the method requires photometric precision of better than ∼ 1%.

Spontaneous Cyclic Levitation of Glycerol‐Water Droplets at Low Pressures
Advanced Science, EarlyView.Under low pressure, a minute glycerol addition transforms the chaotic dynamics of freezing water droplets into cyclic levitation. Freeze‐concentration preserves liquid pathways that relax expansion‐induced stress, while freezing point depression weakens asymmetric vaporization recoil.

A multi-scale comparison of polar vortices on Earth, Mars, Titan, and Venus
地球与行星物理论评Although previous studies have analyzed the unique structural characteristics of the polar vortices on Earth, Venus, Mars, and Titan, the understanding of the polar vortices on Venus and Titan is primarily based on small-scale case studies due to the ...

Advanced Energy Materials, EarlyView.Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

Advanced Energy Materials, EarlyView.This work reports 2D MXene‐derived TiN thin films with (111)‐preferred orientation for transparent Ta3N5 photoanodes, demonstrating effective electron transfer behavior. All‐nitride electron‐collection architecture based on MXene‐derived TiN and n‐GaN resolves a long‐standing materials bottleneck between photocarrier transport and light transmission in

Thermoradiative Diodes Using Black Phosphorus van der Waals Materials
Advanced Energy Materials, EarlyView.We demonstrate thermoradiative diodes based on black phosphorus (bP${\rm bP}$)/molybdenum disulfide (MoS2$MoS_2$) van der Waals heterojunctions which generate power by exchanging photons with a colder environment. The bandgap of black phosphorus is well positioned to exchange photons with outer space through the mid‐wave atmospheric window.

Forming Massive Terrestrial Satellites through Binary-exchange Capture
The Planetary Science JournalThe number of planetary satellites around solid objects in the inner solar system is small either because they are difficult or unlikely to form or because they do not survive for astronomical timescales.
