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

open access: yesContact 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.

Progress and Challenges of Using Itaconic Acid for Sustainable, Competitive and Advanced Polymers in Additive Manufacturing

open access: yesAdvances in Polymer Technology, Volume 2026, Issue 1, 2026.
Despite efforts to develop polymeric materials using renewable feedstocks, there is a continued reliance on (meth)acrylates for several additive manufacturing (AM) technologies, diminishing their overall sustainability. On the other hand, itaconic acid presents itself as an opportunity to resolve these shortcomings as a biobased source of unsaturation,

Application of Crosslinked Epoxy‐Based Gel Polymer Electrolytes for Li‐Ion Battery

open access: yesMacromolecular Materials and Engineering, Volume 310, Issue 12, December 2025.
Crosslinked gel polymer electrolytes are prepared using epoxidized soybean oil (ESO) and bisphenol A diglycidyl ether (DGBEA). The resulting polymer electrolytes exhibited a wide electrochemical stability window (up to 4.2 V), ionic conductivity in the range of 10−4 S cm−1, and a cation transference number between 0.47 and 0.76.
