Mechanochemical Engineered Sulfur Copolymers Onto Group 13 and Related Fillers Through Lewis Acid‐Base Pairing

open access: yesAdvanced Science, EarlyView.
Green mechanochemical copolymerization was developed for universal interfacial modification of Group 13 and related fillers. By leveraging Lewis acid–base coordination to anchor sulfur‐containing polymers—validated via multiscale characterization and DFT—this versatile method boosts performance across liquid fuels, thermal‐shielding materials, and ...

Numerical Modelling of Low Rank Coal for Spontaneous Combustion

open access: yes, 2014
Transportating and stockpiling low-rank coals are puts them under risk of spontaneous combustion, because they are very easy to get self heating ignition after drying or removing moisture due to high moisture and oxygen contents.

Toward Sustainable Separation and Recovery of Critical Metals From Discarded Industrial Perovskite Solar Modules

open access: yesAdvanced Science, EarlyView.
An architecture‐guided recycling process enables selective metal recovery from end‐of‐life perovskite solar modules by exploiting interfacial accessibility and calcination‐induced phase transformation. The process achieves >99.8% Pb removal, >99.7% In recovery, and >96.1% Cu recovery, while selectively retaining Sn in leaching residue.

A novel and effective method for removing organic sulfur from low rank coal

open access: yes, 2016
The organic sulfur in coal is difficult to remove using gravity separation, oil agglomeration and flotation. Even though chemical leaching/oxidation and bio-desulfurization by bacteria are considered as the efficient methods in organic sulfur removal ...

Toward Sustainable Smart Packaging: Demonstration of Laser‐Induced Graphene Sensors on Orange‐Based Substrates

open access: yesAdvanced Electronic Materials, EarlyView.
Orange peel waste is directly transformed into biodegradable bioplastic films and converted into electronically active laser‐induced graphene (LIG) sensors through single‐step 450 nm laser scribing. Without requiring conductive inks, metallic coatings, or transfer steps, localized photothermal conversion creates porous 3D graphitic networks with sheet ...
