Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction
Advanced Science, EarlyView.Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

Advanced Science, EarlyView.How can humanity achieve lunar self‐sufficiency? We utilize Au topology networks to modify the abundant lunar ilmenite. This catalyst, under sunlight, can convert waste carbon dioxide into space fuel. This design leverages the moon's natural vacuum for green manufacturing, avoiding the waste of gold and serving as “artificial chloroplasts” to sustain ...

Advanced Science, EarlyView.A high‐power hybrid nanogenerator (HP‐HNG) with multi‐degree‐of‐freedom mechanical coupling is reported, integrating multi‐directional wave energy for output to achieve 1 + 1 > 2 energy harvesting. The HP‐HNG achieves a peak output power of 0.764 W, corresponding to a peak power density of 127.303 W m−3. At a wave frequency of 1 Hz, the HP‐HNG delivers

Earth-mass Planets in Tandem Disks
The Astrophysical JournalThis paper presents a new terrestrial planet formation theory demonstrating that Earth-mass planets form naturally in tandem protosolar disks. Our model builds upon tandem planet formation theory, incorporating magneto-rotational instability (MRI ...

Giant planets: Clues on current and past organic chemistry in the outer solar system [PDF]
, 1992 The giant planets of the outer solar system - Jupiter, Saturn, Uranus, and Neptune - were formed in the same flattened disk of gas and dust, the solar nebula, as the terrestrial planets were.

On the interaction between embedded planets and the corotation region of protoplanetary discs [PDF]
, 2015 PhDDisc material in the corotation region librates with respect to low-mass planets on horseshoe trajectories. The exchange of angular momentum associated with this libration gives rise to the non-linear corotation torque (the horseshoe drag).
