Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance

Chemistry – A European Journal, EarlyView.
This review covers the application of the bifunctional approach to photocatalysis as a means to attain (enhanced) enantioselectivity, and, more in general, as a strategy to enhance the catalytic performance through an effective use of short‐lived reaction intermediates.

Dearomatization with Axial‐to‐Central Chirality Conversion

European Journal of Organic Chemistry, EarlyView.
Atropisomers are exciting synthetic targets with unique properties, which find applications in many fields of chemistry. However, considering them as substrates is not very frequent, notably in the context of dearomatization reaction. We wish to discuss the different strategies for the dearomatization of aromatic atropisomers with axial‐to‐central ...

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

Targeting the Ubiquinol-Reduction (Q_i) Site of the Mitochondrial Cytochrome bc₁ Complex for the Development of Next Generation Quinolone Antimalarials

Biology, 2022
Antimalarials targeting the ubiquinol-oxidation (Qo) site of the Plasmodium falciparum bc1 complex, such as atovaquone, have become less effective due to the rapid emergence of resistance linked to point mutations in the Qo site. Recent findings showed a
