Metal-organic frameworks as kinetic modulators for branched selectivity in hydroformylation

Berend Smit, Gerald Bauer, Daniele Ongari, Davide Tiana, Mohamed Tarik

Finding heterogeneous catalysts that are superior to homogeneous ones for selective catalytic transformations is a major challenge in catalysis. Here, we show how micropores in metal-organic frameworks (MOFs) push homogeneous catalytic reactions into kinet ...

Monitoring of Priority Substances in Sediments of Switzerland

Florian Frédéric Vincent Breider, Benoît Jean Dominique Ferrari, Maria del Carmen Casado Martinez

In Switzerland, surface waters are protected by the Swiss Water Protection Ordinance (OEaux) which stipulates that the water quality shall be such that: "the water, suspended matter and sediments contain no persistent synthetic substances to ensure the pro ...

Designing Singlet Fission Candidates from Donor-Acceptor Copolymers

Sergio Vela Llausi, Maria Fumanal Quintana, Jacob Terence Blaskovits

Singlet fission (SF) has demonstrated significant promise for boosting the power conversion efficiency (PCE) of solar cells. Traditionally, SF is targeted as an intermolecular process; however, its dependence on crystal packing makes molecular design diffi ...

A fish intestinal barrier model to assess the interaction with chemicals in vitro

Hannah Inka Schug

The intestinal epithelium acts as vital gate keeper between the fish and its surrounding environment. A single layer of connected epithelial cells forms a selective barrier, which, among other essential functions, is important for nutrient uptake and defen ...

Corncob Biorefinery for Platform Chemicals and Lignin Coproduction: Metal Chlorides as Catalysts

Wu Lan

A facile approach to a corncob biorefinery, focusing on both carbohydrate valorization and lignin stabilization, was proposed to coproduce platform chemicals (glucose, xylose, arabinose, and furfural) and lignin. Different metal chloride prehydrolyses of c ...

Intestinal Fish Cell Barrier Model to Assess Transfer of Organic Chemicals in Vitro: An Experimental and Computational Study

Kristin Schirmer, Hannah Inka Schug, Anze Zupanic, Jenny Maner

We studied the role of the fish intestine as a barrier for organic chemicals using the epithelial barrier model built on the rainbow trout (Oncorhynchus mykiss) intestinal cell line, RTgutGC and the newly developed exposure chamber, TransFEr, specifically ...

Bioconversion of pentose sugars to value added chemicals and fuels: Recent trends, challenges and possibilities

Edgard Gnansounou, Vinod Kumar

Most of the crop plants contain about 30% of hemicelluloses comprising D-xylose and D-arabinose. One of the major limitation for the use of pentose sugars is that high purity grade D-xylose and D-arabinose are yet to be produced as commodity chemicals. Res ...

Direct amidation of esters with nitroarenes

Xile Hu, Chi Wai Cheung, Marten Leendert Ploeger

Esters are one of the most common functional groups in natural and synthetic products, and the one-step conversion of the ester group into other functional groups is an attractive strategy in organic synthesis. Direct amidation of esters is particularly ap ...

Transatlantic Patterns of Risk Regulation: Implications for International Trade and Cooperation

Marie-Valentine Renée Agnès Florin

This report presents a study commissioned by the European Parliament to compare regulatory standards in the EU and the US in four key sectors (food safety, automobiles, chemicals, and pharmaceuticals), chosen for their relevance both to consumer protection ...
