Dynamic Control of Two‐Component Aggregation and Color‐Tunable Emission via Charge‐Transfer Coassembly

Aggregate, Volume 7, Issue 1, January 2026.
Charge‐transfer coassembly enables precise control over the dynamic aggregation process, resulting in morphology evolution from amorphous aggregates to rod‐like and needle‐like microcrystals, accompanied by a significant fluorescence enhancement. This strategy yields widely tunable solid‐state emission from green to orange‐red, unveiling fundamental ...

Size Effects of TiO2 Nanoparticles as Supports for W‐ and NiW‐Catalysts for Selective 3‐Methylthiophene Desulfurization

ChemCatChem, Volume 18, Issue 1, 15 January 2026.
Rounded TiO2 nanoparticles we sucesfully synthesized with modulated sizes from 109 to 22 nm. We observed the WS2 and NiWS active phases forming parallel slabs to the surface. The presence of Ni helped W to be better dispersed, especially on the smallest nanoparticles, which resulted in the highest activity detected among the series.

Polar Diels-Alder Reactions using Heterocycles as Electrophiles. Influence of Microwave Irradiation [PDF]

, 2015
In this work we studied a series of polar Diels-Alder reactions using different heterocycles derivatives acting as electrophiles joint to dienes of different nucleophilicity, analyzing the effect of the microwave irradiation in these processes. We employ

Natural Source Zone Depletion of Crude Oil in the Subsurface: Processes Controlling Mass Losses of Individual Compounds

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract At many petroleum hydrocarbon spill sites, residual spilled product forms a long‐term source of groundwater contamination. The phrase source zone natural depletion is used to refer to the mass loss rates. Overall mass lost under environmental conditions was analyzed using conservative biomarker concentrations for a 1979 oil spill in northern ...
