Heterogeneously Catalyzed Reductive Depolymerization of Lignin to Value-Added Chemicals.

Lignin is an abundant renewable source of aromatics, but its complex heterogeneous structure poses challenges for its depolymerization and valorization. Heterogeneously catalyzed reductive depolymerization (HCRD) has emerged as a promising approach, utilizing heterogeneous catalysts to facilitate selective bond cleavage in lignin and hydrogen transfer to stabilize the products under mild conditions. This review provides a comprehensive understanding of the hydrogen transfer mechanisms in HCRD, involving different hydrogen sources, including molecular hydrogen, alcohols, formic acid, etc.

Experimental study and techno-economic analysis of co-processing system for treatment of food waste with various impurities.

The study assessed a co-processing system segregating food waste (FW) with different impurities into liquid (slurry) and solid fractions and treated using anaerobic digestion (AD) and pyrolysis (Py), respectively, which is defined as ADCo-Py. Biomethane potential tests showed higher methane yield from the FW slurry fraction (572.88 mL/gVS) compared to the whole FW (294.

Market access for Chinese herbal medicinal products in Europe-A ten-year review of relevant products, policies, and challenges.

Background: With increased consumer demand in Europe for natural and efficacious health products, the use of herbal products in the market is rising. Products of Chinese herbal medicine (CHM) could greatly expand European consumer options; however, only seven herbal medicinal products (HMPs) based on CHM formulae have been registered in the European Union (EU) since 2012.

Purpose: This study reviews the ten-year registration status of HMPs based on CHM formulae in Europe and identifies major challenges and possible solutions for pharmaceutical companies seeking market access for new HMPs.

Validation of residual SYNTAX score with second-generation drug-eluting stents: one-year results from the prospective multicentre SEEDS study.

Aims: The SYNTAX score has been proposed as a valuable tool to characterise coronary anatomy prospectively based on its complexity. This study evaluated the prognostic value on adverse outcomes of the residual SYNTAX score (rSS) in patients with complex lesions treated with an everolimus-eluting stent (EES).

Methods And Results: One thousand eight hundred and fifty-one patients with small vessel (reference diameter <2.
