Contribution to the study of Himatanthus sucuuba: latex macromolecule, microelements and carbohydrates [PDF]

open access: yesActa Amazonica, 2003
The polymeric material in the latex of Himatanthus sucuuba (Spruce) Woodson was identified by spectroscopic methods as cis-polyisoprene (Mn = 192; Mw = 571; Mw/ Mn = 2.97). ICP-MS analysis of microelements in the aqueous phase showed the most abundant to

Post‐Additional Proteins into Rubber Matrices Behave as Filler to Reinforce Rubber

open access: yesMacromolecular Materials and Engineering, EarlyView.
The post‐additional proteins exhibit a reinforcement effect regardless of the origin of the rubber. The proteins are lyophilized to obtain a powder, which is then incorporated into the rubber matrices using a solution‐mixing process. These findings suggest that protein can function as a reinforcing filler depending on the rubber preparation process ...

Diazirines Beyond Photoaffinity Labeling: A Comprehensive Overview of Applications in Biological Sciences, Materials Chemistry, and NMR‐Spectroscopy

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Diazirines are three‐membered, nitrogen‐containing heterocycles that decompose under light or heat to generate carbenes. For the past two decades, they have served mainly as minimally invasive tags in photoaffinity labeling (PAL). More recently, their value as versatile carbene precursors has been recognized.
