Dynamical rearrangement of super-Earths during disk dispersal I. Outline of the magnetospheric rebound model

open access: yes, 2017
The Kepler mission has discovered that multiple close-in super-Earth planets are common around solar-type stars, but their period ratios do not show strong pile-ups near mean motion resonances (MMRs).

Snap and Jump: How Elastic Shells Pop Out

open access: yesAdvanced Robotics Research, EarlyView.
Indent an elastomeric shell and let it go. The spherical shells can store and release the elastic energy. Desktop‐scale experiments, material point method simulation, and analytical theory uncover the fundamental mechanism of soft jumping robots.

Minor satellites and the Gaspra encounter [PDF]

open access: yes
Observational evidence, especially from occultations and radar, indicate that satellites of minor planets are numerous and commonplace. This leads to the prediction that the Galileo spacecraft will find many such 'minor satellites' at the upcoming close ...

The Effect of Condensates on the Characterization of Transiting Planet Atmospheres with Transmission Spectroscopy

open access: yes, 2005
Through a simple physical argument we show that the slant optical depth through the atmosphere of a "hot Jupiter" planet is 35-90 times greater than the normal optical depth.

p‐Cu(OH)2/n‐SrTiO3 Heterojunction for Efficient Photocatalytic Hydrogen Production

open access: yesAdvanced Sustainable Systems, EarlyView.
Improving the efficiency of photocatalysts in the hydrogen evolution reaction relies on developing cost‐effective co‐catalysts. This study focuses on p‐Cu(OH)2/n‐SrTiO3 heterojunctions for efficient hydrogen production. 1 wt.% Cu‐based co‐catalyst significantly enhances performance, achieving ≈3.5 times higher hydrogen production compared to pristine ...

Polyoxometalate Imide‐Linked Molecules, Covalent Organic Polymers, and Frameworks: Dimensionality Effects on Supercapacitors Performance

open access: yesAdvanced Sustainable Systems, EarlyView.
This study explores polyoxometalate‐based hybrids with varying dimensionalities, linking molecular, polymeric, and framework structures to supercapacitor performance. The results highlight how structural tuning enhances surface area, porosity, and charge transport, offering insights into designing efficient energy storage materials.

The growth of planets by pebble accretion in evolving protoplanetary discs

open access: yes, 2015
The formation of planets depends on the underlying protoplanetary disc structure, which influences both the accretion and migration rates of embedded planets. The disc itself evolves on time-scales of several Myr during which both temperature and density

Laser‐Induced HKUST‐1 Derived Porous Electrocatalyst: an Innovative Approach to Boost Sustainable Ammonia Synthesis

open access: yesAdvanced Sustainable Systems, EarlyView.
A zero‐waste, eco‐friendly, binder‐free, scalable, rapid, and one‐pot laser carbonization approach fabricates a coppercuprous oxide/carbon electrocatalyst derived from HKUST‐1 metal‐organic framework for efficient nitrate reduction to ammonia. The catalyst exhibits high ammonia yield, excellent Faradaic efficiency, and robust stability.
