Liquid Crystal Elastomers Under Confinement: A Review of Template‐Based Fabrication and Applications

open access: yesAdvanced Engineering Materials, EarlyView.
Template‐assisted confinement offers powerful ways to control the alignment, structure, and function of liquid crystal elastomers. This review highlights several templating strategies and details how geometry and interfaces shape material responses.

Geomagnetic Storm‐Induced Plasma Density Enhancements in the Southern Polar Ionospheric Region: A Comparative Study Using St. Patrick's Day Storms of 2013 and 2015

open access: yesSpace Weather, 2020
The occurrence of St. Patrick's Day (17 March) geomagnetic storms during two different years (2013 and 2015) with similar solar flux levels but varying storm intensity provided an opportunity to compare and contrast the responses of the ionosphere ...

Dynamical Interactions and Mass Loss within the Uranian System

open access: yesThe Planetary Science Journal, 2023
The origin and evolution of planetary rings and moons remains an active area of study, particularly as they relate to the impact history and volatile inventory of the outer solar system.

Efficient and Scalable Radiative Cooling for Photovoltaics Using Solution‐Processable and Solar‐Transparent Mesoporous Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...

Rapid protoplanet formation in the outer Solar System recorded in a dunite from the carbonaceous chondrite reservoir

open access: yesCommunications Earth & Environment
Constraining the timing of accretion, differentiation, and breakup of early-formed protoplanets helps to unravel the Solar System’s evolution. The recent discovery of the oldest crustal material, Erg Chech 002, has provided important constraints on the ...

Triggered Star Formation Inside the Shell of a Wolf-Rayet Bubble as the origin of the Solar System

open access: yes, 2017
A critical constraint on solar system formation is the high $^{26}$Al/$^{27}$Al abundance ratio of 5 $\times 10^{-5}$ at the time of formation, which was about 17 times higher than the average Galactic ratio, while the $^{60}$Fe/$^{56}$Fe value was about

Stabilized Intermediate Phase Via Pseudo‐Halide Anions Toward Highly Efficient and Light‐Soaking Stable Perovskite Solar Cells

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.

Aqueous alteration without initial water: possibility of organic-induced hydration of anhydrous silicates in meteorite parent bodies

open access: yesEarth, Planets and Space, 2021
Early evolution of Solar System small bodies proceeded through interactions of mineral and water. Melting of water ice accreted with mineral particles to the parent body results in the formation of secondary minerals, the so-called aqueous alteration ...

Dynamics of the Kuiper Belt [PDF]

open access: yes, 1999
Our current knowledge of the dynamical structure of the Kuiper Belt is reviewed here. Numerical results on long term orbital evolution and dynamical mechanisms underlying the transport of objects out of the Kuiper Belt are discussed.

Jovian Early Bombardment: planetesimal erosion in the inner asteroid belt

open access: yes, 2012
The asteroid belt is an open window on the history of the Solar System, as it preserves records of both its formation process and its secular evolution.
