Integrated Chemoenzymatic Synthesis of the mRNA Vaccine Building Block N1‐Methylpseudouridine Triphosphate

Angewandte Chemie International Edition, Accepted Article.
Pseudouridine‐5’‐triphosphate (ΨTP) and the N1‐methylated derivative (m1ΨTP) are critical monomer building blocks of the currently used mRNA vaccines, yet efficient methods of their synthesis from readily accessible substrates remain underdeveloped. We herein report notably atom‐economic and high‐yielding biocatalytic route toward ΨTP (83% yield) and ...

“Dead Lithium” Formation and Mitigation Strategies in Anode‐Free Li‐Metal Batteries

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
Anode‐free lithium metal batteries, though promising due to their high energy density, face challenges from dead lithium formation. “Dead lithium”, disconnected from the anode, causes capacity loss, increased resistance, and safety risks. This review explores the origins of dead lithium, its impact on battery performance, and potential strategies for ...

Increasing Redox Potential of Pyromellitic Diimide by Chemical Modifications: Toward High‐Voltage Organic Positive Electrode for Lithium Battery

Batteries &Supercaps, EarlyView.
Chemical modifications of soluble pyromellitic diimide derivatives with bromo‐ and cyano‐ electron‐withdrawing groups instead of hydrogen lead to an increase of redox potential of 210 and 420 mV respectively compared to the reference. Lithium batteries are considered as the most promising electricity storage solution to support the energy transition ...

Pine bio‐oil based biorefinery procedure for the production of antioxidants, acids, and sugars

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract In this study, a wood‐based biorefinery with Pinus halepensis biomass was developed to obtain acids, sugars, and antioxidants with high recovery yields. Pine wood residues from sustainable forest management are transformed into bio‐oil (BO) and separated into value‐added chemicals with an integrated and innovative methodology.

Strategic techniques for upgrading bio‐oil from fast pyrolysis: a critical review

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Pyrolysis has been the subject of extensive scientific research due to its potential application to various waste streams and byproducts from different production systems. One of its main products is the liquid fraction known as bio‐oil – a complex material composed of a wide variety of organic molecules and a significant water content.

Sequential fractionation and polyoxometalate‐catalyzed oxidation of lignocellulosic biomass improves cellulose purity and formic acid yield

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Lignocellulosic biomass is an important source of renewable chemicals and materials but its full valorization is necessary in order to achieve economic and sustainability goals. This study proposes a two‐step approach for the valorization of lignocellulosic biomass combining solvent‐assisted fractionation and catalytic oxidation with molecular
