Age Analysis of Extrasolar Planets: Insight from Stellar Isochrone Models
The Astronomical JournalThere is growing evidence from stellar kinematics and galactic chemical evolution suggesting that giant planets ( M _P ≥ 0.3 M _J ) are relatively young compared to the most commonly occurring population of small planets ( M _P < 0.3 M _J ).

Advanced Energy Materials, EarlyView.Silicon‐boron alloy nanoparticles are incorporated into lithium‐ion batteries as the active anode material and enhance the battery cycle and calendar lifetime with improved interfacial chemical passivation. This passivation is afforded by the strong surface dipoles imparted on the particles from Lewis acidic surface boron.

Long-term Stability of Planetary Systems Formed from a Transitional Disk
The Astrophysical Journal, 2023 Transitional disks are protoplanetary disks with large and deep central holes in the gas, possibly carved by young planets. Dong & Dawson simulated systems with multiple giant planets that were capable of carving and maintaining such gaps during the disk

Advanced Energy Materials, EarlyView.Partially disordered Cr‐based Li‐rich oxides are developed, featuring ordered, layered‐like environments integrated through a common oxygen sublattice with cation‐mixed regions. This activates new Li+ diffusion channels, enabling these cathodes to be used in their as‐synthesized form with micron‐sized particles.

Looking into the Giant Planets [PDF]
Science, 2004 Jupiter and Saturn are mostly made up of hydrogen and helium, but details of their precise composition and the evolution and structure of their interiors are hard to come by. In his Perspective, Fortney highlights recent model studies that have shed light on the likely structure and evolution of these giant planets.

Electrodeposited Iron‐Incorporated Cobalt Phosphide for Improved Supercapacitor Applications
Advanced Energy and Sustainability Research, EarlyView.The electrodeposition method has been used to synthesize Fe–CoP deposited on nickel foam, resulting in excellent cycling stability and capacitance retention compared to CoP and FeP. Furthermore, a detailed charge storage mechanism, emphasizing the enhanced electrochemical performance has been discussed. Supercapacitors have gained significant attention

Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
