Mapping the potential energy surfaces for ring-closing metathesis reactions of prototypical dienes by electronic structure calculations [PDF]
, 2011 The potential energy surfaces for ring-closing metathesis reactions of a series of simple alpha,omega-dienes which lead to 5-10 membered ring products, have been explored using density functional theory methods.

Journal of Applied Entomology, Volume 150, Issue 2, Page 243-253, March 2026.ABSTRACT Previous studies on Cydia pomonella eggs have demonstrated reliable egg adhesion to the leaves and fruits of various apple cultivars. In contrast to biological substrates, this study is focused on standardised synthetic substrates to measure egg pull‐off forces and determine adhesive strength, allowing for an unbiased comparison with other ...

Contact Dermatitis, Volume 94, Issue 2, Page 125-136, February 2026.The data demonstrates that allergic contact dermatitis is common in WW with OD. The most important allergens include resins (including epoxy resin) and plant‐derived substances (including colophonium). The high share of WW with allergic contact dermatitis and face dermatitis hampers preventive efforts.

Thiophene Derivatives as Versatile Precursors for (Hetero)Arene and Natural Product Synthesis
Angewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.Hidden but Powerful: Thiophenes and their saturated analogues have been demonstrated to be versatile C4‐building blocks that can be rapidly applied to natural product synthesis and the construction of functionalized (hetero)arenes. This minireview aims to provide a concise overview of the strategies and implementations of these sulfur‐containing ...
