Novel neo-clerodane diterpenoids from Teucrium quadrifarium and their anti-ferroptosis effect

Natural Products and Bioprospecting
Teucrifarides A–D (1–4), four previously unreported neo-clerodane-type diterpenoids, combined with sixteen known analogs (5–20), were purified from Teucrium quadrifarium.

Crosslinking of XNBR with polyvalent epoxy compounds (PECs) for accelerator-free rubber films

Results in Materials
The serious problems of skin inflammations (dermatitides) observed in the users of rubber gloves caused by type I or type IV hypersensitivity strongly require their new manufacturing methods free from these irritations.

Kinetic behavior of the reaction between silica and epoxidized liquid rubber

Polímeros
The use of epoxidized rubber as compatibilizer in silica-filled rubber compounds has been proposed in literature. However, the investigation of the reaction kinetics between the epoxy groups and the hydroxyl groups at the silica surface is not yet ...
