Antarctic climate, Southern Ocean circulation patterns, and deep water formation during the Eocene [PDF]

open access: yes, 2017
We assess early-to-middle Eocene seawater neodymium (Nd) isotope records from seven Southern Ocean deep-sea drill sites to evaluate the role of Southern Ocean circulation in long-term Cenozoic climate change.

3D‐Printed Architected Anisotropic Channels for Ultrafast Solar‐Driven Interfacial Evaporation via Localized Thermal Management and Water Layer Structuring

open access: yesAdvanced Science, EarlyView.
A 3D‐printed anisotropic channel evaporator integrates directional geometry with aligned titanium oxide, boron nitride, and chitosan networks to coordinate photon absorption, heat localization, and water transport. Phonon‐guided thermal pathways and interfacial water structuring enable ultrahigh evaporation rates and long‐term salt‐resistant solar ...

Evidence for Recent Wet-Based Crater Glaciation in Tempe Terra, Mars. [PDF]

open access: yes, 2018
[Introduction] Mars’ mid-latitudes host abundant putative debris-covered water-ice glaciers (viscous flow features; VFF). Eskers emerging from 110-150 Myr-old VFF in Phlegra Montes and Tempe Terra provide evidence for rare occurences of past ...

Limit cycles can reduce the width of the habitable zone

open access: yes, 2016
The liquid water habitable zone (HZ) describes the orbital distance at which a terrestrial planet can maintain above-freezing conditions through regulation by the carbonate-silicate cycle.

Gliese 581d is the first discovered terrestrial-mass exoplanet in the habitable zone [PDF]

open access: yes, 2011
It has been suggested that the recently discovered exoplanet GJ581d might be able to support liquid water due to its relatively low mass and orbital distance.

Neural Network‐Based Permittivity Engineering of Magnetic Absorbers for Customizable Microwave Absorption

open access: yesAdvanced Science, EarlyView.
A neural network‐enabled permittivity engineering paradigm is introduced, transcending traditional trial‐and‐error design. By decoupling electromagnetic parameters and screening a high‐throughput feature space, an ultrathin (1.0 mm) magnetic absorber is inversely designed, experimentally achieving a superior and customizable 5.1 GHz bandwidth and ...

A “Hot Spring” Mimetic Aerogel Loaded with Multiple Amino Acids Modulates the Chronic Inflammatory Microenvironment Through Metabolic Reprogramming

open access: yesAdvanced Science, EarlyView.
The SrCuSi4O₁₀ bioceramic particles mimic the effects of hot spring therapy by increasing the local wound temperature, which enhances the absorption of amino acids and stimulates cell metabolism. The amino acid uptake supports cellular glutathione redox reactions, helping to mitigate oxidative stress.

Subterranean glacial spillways: an example from the karst of South Wales, UK [PDF]

open access: yes, 2013
Many karst areas in the UK have been glaciated one or more times during the last 0.5 Ma, yet there are few documented examples of caves in these regions being affected by glacial processes other than erosion.

Defect‐Rich 2D Layered Double Hydroxides Enhance Sonodynamic Antibacterial Therapy

open access: yesAdvanced Science, EarlyView.
This study develops defect‐rich ultrathin ZnCuW‐LDH nanosheets (DR‐ZnCuW‐LDH) via acid etching. DR‐ZnCuW‐LDH exhibits fourfold enhanced US‐triggered ROS production due to oxygen defects and electronic modulation, demonstrating potent antibacterial efficacy in vitro/vivo.
