Water Adsorption‐Induced Color Sensor: Insight Into the Sensing Mechanism and Interfacial Engineering for Improved Responsiveness

Advanced Functional Materials, EarlyView.
We report a unique color‐sensing phenomenon of a TiO2/SbSI:Sb2S3 device utilizing X‐ray absorption. Based on the revealed penetration and adsorption of water onto TiO2, we successfully improved the color response speed and sensitivity by incorporating a hydrophilic polymer interlayer, thereby opening up opportunities for photodetection applications ...

14C AMS dates of unidentified organic material from the ice wedges of the Batagay Yedoma and its stable isotope сcomposition [PDF]

Detailed sampling of two syngenetic ice wedges (IW-17 and IW-20) for isotope analysis was carried out in the exposure of the thermo-erosional ravine in the southeastern part of the Batagay megaslump. In total, results of 105 measurements for IW-17 and 59

Bioinspired Hierarchically Interconnected Supermacroporous Hydrogels via Dual‐Templating for Rapid Atmospheric Water Harvesting

Advanced Functional Materials, EarlyView.
Inspired by lung alveolar architecture, a dual‐templating strategy combining CO2 bubble and ice templating creates mechanically robust super‐macroporous hydrogels with highly interconnected transport pathways. The resulting material achieves 3.37× faster moisture sorption and 1.72× higher solar‐driven water release than single‐templated counterparts ...

Regional Patterns and Asynchronous Onset of Ice-Wedge Degradation since the Mid-20th Century in Arctic Alaska

Remote Sensing, 2018
Ice-wedge polygons are widespread and conspicuous surficial expressions of ground-ice in permafrost landscapes. Thawing of ice wedges triggers differential ground subsidence, local ponding, and persistent changes to vegetation and hydrologic connectivity

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

Advanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

A Numerical Simulation Method for Investigating the Fluid–Structure–Ice Coupling Mechanism of a Wedge Breaking through Ice into Water

Applied Sciences
We aimed to investigate the fluid–solid–ice coupling mechanism as structures break through ice into water. Using LS–DYNA finite element software, a numerical simulation method is established, based on the ALE flow–solid coupling method, and the penalty ...

Interface Engineering via Sb2Te3 Deposition Enables High‐Performance SWCNT Film Thermoelectrics

Advanced Functional Materials, EarlyView.
SWCNTs are promising for flexible thermoelectrics but suffer from low performance. Here, cold‐pressed SWCNT films combined with deposited Sb2Te3 form engineered interfaces that enhance charge transport and energy filtering. The composite achieves a high power factor (25.82 µW cm−1 K−2) and delivers a power density of 3 mW cm−2 at ΔT = 40 K, with ...

Electrostatically‐Stabilized PEG‐Free Lipid Nanoparticles for Systemic Nucleic Acid Delivery

Advanced Functional Materials, EarlyView.
This work describes non‐PEGylated layered lipid nanoparticles (nonPEG LLNPs), a gene delivery platform that improves upon standard PEGylated LNPs via electrostatic adsorption of charged polymers. nonPEG LLNPs maintain colloidal stability under biological stresses, enhance circulation time, and mitigate accelerated blood clearance and hepatic ...
