Egg Adhesion of the Codling Moth Cydia pomonella L. (Lepidoptera, Tortricidae) to Synthetic Substrates

Journal of Applied Entomology, EarlyView.
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 ...

Epidemiological Comparative Study on Contact Sensitisations in Woodworkers With Occupational Dermatitis: Patch Test Data of the Information Network of Departments of Dermatology, 1999 to 2023

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.

Ruthenium-Based Heterocyclic Carbene-Coordinated Olefin Metathesis Catalysts [PDF]

, 2010
The fascinating story of olefin (or alkene) metathesis (eq 1) began almost five decades ago, when Anderson and Merckling reported the first carbon-carbon double-bond rearrangement reaction in the titanium-catalyzed polymerization of norbornene.

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 ...

Syntheses and Structures of Water‐Soluble Model Complexes Related to the Active Site of Molybdenum and Tungsten‐Dependent Oxidoreductases

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.
Complex salts with potassium counter cations and bisdithiolene oxido molybdate or tungstate anions are water tolerant and soluble in purely aqueous medium. Four different synthetic routes to water‐soluble complexes of the type K2[MOx(dt)2] (M = Mo, W; dt = ene‐1,2‐dithiolate, x = 1, 2) applicable to different ligand precursors are presented.

Titanium‐Catalyzed Intermolecular Hydrothiomethylation of Alkenes

Chemistry – A European Journal, Volume 32, Issue 1, 2 January 2026.
Hermetically sealable, inexpensive 42‐well aluminum reactor blocks are used to explore new reactivities of air‐ and moisture‐sensitive titanium catalysts. As a result, methyl sulfides undergo efficient α‐alkylation with alkenes in the presence of a titanium catalyst precursor, a formamidinato ligand, and a Lewis acid, yielding branched ...
