Heterogeneous Wettability‐Based Construction of Two‐Phase Interfaces for Underwater Reversible Adhesion

open access: yesAdvanced Science, EarlyView.
The design employs heterogeneous wettability surfaces that construct stable oil‐water interfaces to achieve robust and rapid reversible adhesion. Linear enhancement of adhesion strength is realized through multi‐interface patterning. This adhesive enables rapid on‐demand detachment within five seconds via voltage‐induced electrolysis, offering a level ...

Heterogeneity‐Guided Interlayer Tuning in Vermiculite‐MOF Membranes for Efficient Li+/Mg2+ Separation

open access: yesAdvanced Science, EarlyView.
Heterogeneity‐guided interlayer engineering is achieved by integrating porous MOF nanosheets into a 2D vermiculite laminate, reprogramming ion transport pathways. The resulting hybrid membranes combine sub‐nanoconfinement and charge heterogeneity, enabling accelerated Li+ transport and reinforced Mg2+ exclusion.

Highly Efficient Extraction of 212 Pb/212Bi from the Decay Chain of 232Th‐Based on Anion Exchange in Bromide Medium

open access: yesAdvanced Science, EarlyView.
This work provides an effective strategy for selectively extracting 212Pb and 212Bi from the decay chain of 232Th as well as its mechanism illustration. Using the novel strategy, 2.07 MBq of 212Pb is successfully separated from 232Th and its daughters, which enables the supply of 212Pb/212Bi directly from the abundant natural thorium resource to be ...

Nanoscale Secondary Ion Mass Spectrometry for Quantifying Membrane Fouling: Fouling Layer Structure and Chemical Interaction

open access: yesAdvanced Science, EarlyView.
Nanoscale secondary ion mass spectrometry (Nano SIMS) is established as a powerful analytical tool to visualize and quantify the membrane fouling layers. ABSTRACT Membrane technology has garnered considerable attention for applications in wastewater treatment and resource recovery. Nevertheless, membrane fouling remains a major barrier, yet the lack of

Volcano‐Inspired Dual‐Carbon Network Aerogel for High‐Performance Solar Evaporation With Edge‐Directed Salt Crystallization and Recovery

open access: yesAdvanced Science, EarlyView.
A volcano‐inspired dual‐carbon aerogel featuring hierarchical conduits and an outer carbon‐fiber shell directs rapid water transport, confines heat, and enables directional salt migration. Radial temperature gradients in the conical structure trigger Marangoni‐driven edge‐localized salt crystallization while maintaining an unobstructed photothermal ...

Environmental and geodynamic characteristics of the formation of potassium salts deposits (on the example of the Stebnytsk deposit of the Ukrainian Carpathians)

open access: yesМінеральні ресурси України
The Stebnytsy salt deposit is located in the internal Boryslav-Pokut subzone of Precarpathia (Ukraine). Mine No. 2 was operated for more than 20 years. During this period, about 15 million m3 of man-made voids were formed and not laid.
