Fractionation of Wood Biomass With Thiolactic Acid and Choline Chloride‐Based Solvent Into White Lignin for Sustainable Cooling Applications

open access: yesChemSusChem, EarlyView.
A novel and highly efficient wood biomass fractionation method was developed to produce white lignin, exhibiting the brightest color reported to date. The process yielded white lignin with high yield, excellent visible light reflectance, and elevated infrared emissivity, highlighting its potential as an active material for passive radiative cooling ...

Optimizing Intermediate Adsorption on FeNi3 Alloy by Substrate Defect‐Engineering for Enhanced Oxygen Electrocatalysis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The presence of carbon edge defects and graphitic valley nitrogen significantly alters the energy band structure of the catalyst, enhancing the desorption of oxygen‐containing intermediates and thereby improving the performance of the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and zinc‐air battery (ZAB).

Copper‐Based Conductive Nanoinks: Scalable Synthesis via Continuous‐Flow Microwave‐Assisted Polyol Process

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Microwave‐assisted polyol synthesis in continuous flow produces metallic Cu nanoparticles, using ethylene glycol as solvent and reducing agent, lignin to stabilize the colloid and prevent oxidation, and metal‐seeds for particle size control. Metallic copper nanoparticles are a promising alternative to gold and silver in printed electronics due to their
