Flexible Chemiresistive Chitosan‐Glycerol Sensors on Laser‐Induced Graphene Electrodes for Room‐Temperature Ammonia Detection

Advanced Materials Technologies, EarlyView.
Flexible Chitosan‐glycerol sensor integrated with porous laser‐induced graphene (LIG) electrodes enable room‐temperature chemiresistive detection of ammonia (NH3) and proof‐of‐concept detection of fish spoilage. ABSTRACT We report a metal‐free sensor platform combining laser induced graphene (LIG) electrodes with drop‐deposited, glycerol‐plasticized ...

Photocatalytic Lignin Depolymerization and Cross‐Coupling With Alcohols to Produce Unsymmetric Aromatic Diols

Angewandte Chemie, EarlyView.
A photocatalytic approach for efficient one‐pot direct lignin depolymerization and subsequent cross‐coupling with alcohols for the production of unsymmetrical aromatic diols has been demonstrated. ABSTRACT Conversion of lignin into chemical products typically involves two separate steps, such as depolymerization and subsequent upgrading of monomers ...

Polyurethane Depolymerization With Alkyl, Aryl, and Mixed Carbonates. [PDF]

ChemSusChem
The depolymerization of polyurethane foams strongly depends on carbonate structure. Aryl carbonates improve hard‐segment solubility but generate side products. Alkyl carbonates give cleaner products yet suffer from limited hard‐block solubility and require anisole as a cosolvent. Mixed carbonate systems balance these effects, improving solubility while

Facet‐Dependent Water Inhibition of Alkanol Dehydration on TiO2 via Distinct Water–Alkanol Complexes

Angewandte Chemie, EarlyView.
Water inhibits alkanol dehydration on TiO2 through facet‐dependent manners via distinct IPA‐water complexes. On TiO2(001), water forms a strongly hydrogen‐bonded isopropoxide–H2O complex that readily dominates the surface and substantially elevates the activation barrier, whereas on TiO2(101), water weakly hydrogen‐bonds to molecular IPA, resulting in ...
