Dissolved humic substances supplied as potential enhancers of Cu, Cd, and Pb adsorption by two different mangrove sediments [PDF]

, 2018
Purpose The external supply of humic substances has been recently suggested for the remediation of metal-polluted sediments; however, little is known about how to supply them and their effects on metal mobility.

Eco‐Friendly Schiff Base Cellulosic Adsorbent for Selective Removal of Cationic Dyes from Petroleum Wastewater: Synthesis, Characterization, and Application

Advanced Materials Interfaces, EarlyView.
The porous HMC selectively captures cationic dyes (MB and MG) from contaminated water, transforming dark, dye‐laden effluent into clean water. ABSTRACT Our investigation explores the exclusion of two health‐risk cationic dyes (e.g., Methylene Blue (MB) and Malachite Green (MG)) using a novel hydrazone‐modified cellulose (HMC) adsorbent synthesized via ...

Stepwise De‐solvation and Diffusion Kinetics of Hydrated Zn‐ion in Hierarchical Porous Carbon Anode for Improved EDLC Behavior

Advanced Science, EarlyView.
The size mismatch between the micropore channel and [Zn(H2O)6]2+ in porous carbon anode during the discharge process was addressed by regulating the hierarchical channel. The inducted stepwise de‐solvation of [Zn(H2O)6]2+ significantly reduced its de‐solvation energy, promoted the EDLC behavior, and strengthened the diffusion kinetic.

Two‐Dimensional La2CoO4 Perovskite Oxide Enabled by Phonon‐Resonance‐Driven Exfoliation for High‐Performance Gas Sensing

Advanced Science, EarlyView.
Few‐layer La2CoO4 nanosheets are produced via phonon‐resonance‐assisted cleavage of the rock‐salt layers in the Ruddlesden‐Popper structure under the 20 kHz resonance condition, enabling controlled exfoliation into ultrathin sheets. The nanosheets show improved gas‐sensing capability, delivering an 86.67% response to 1 ppm NO2 at room temperature ...

Heterostructure‐Engineered Conductive MOFs Coupled with MoSe2@MXene Framework for Efficient and Selective Lithium Extraction from Salt Lake Brine via Capacitive Deionization

Advanced Science, EarlyView.
This schematic illustrates a capacitive deionization (CDI) system for the selective extraction of lithium from salt‐lake brine. The system employs a cathode fabricated from the Fe‐THBQ@MoSe2@MXene composite alongside an activated carbon (AC) anode. Upon applied voltage, the cathode demonstrates high efficiency in capturing Li+ ions while effectively ...
