In situ synthesis of natural rubber latex-supported gold nanoparticles for flexible SERS substrates

, 2015
Natural rubber latex (NRL) from Hevea brasiliensis was used as a matrix to synthesize gold nanoparticles (AuNPs), leading to an organic-inorganic hybrid latex of NRL-supported AuNPs (AuNPs@NRL).

Natural Rubber Latex Allergy

, 2012
Natural rubber latex (NRL) is a milky fluid from the Hevea brasiliensis (Hev b) tree, which functions as a protective sealant (Ownby, 2002). Because of its excellent elastic properties, it is widely used in the manufacture of medical devices and in a variety of everyday articles such as gloves, condoms, balloons, baby nipples, syringe plungers, and ...

State‐Level Politics in Forest Governance: The Role of the Narrative‐Policy Nexus in the Brazilian Amazon

Environmental Policy and Governance, EarlyView.
ABSTRACT Deforestation and its social impacts are an enduring challenge in agrarian frontiers, especially in the tropics. Fueled by global demand for commodities, this process is mediated by ideas, concepts, meanings, and policies that uphold socioenvironmental degradation. A key and understudied—arena in which this mediation occurs is the sub‐national

Latex Serum‐Derived Supramolecular Networks Enable Toughening of Natural Rubber

Macromolecular Rapid Communications, EarlyView.
Latex‐serum addition enhances strain‐induced crystallization (SIC) toughening in natural rubber, increasing tearing strength and extending the SIC activation window. Supramolecular networks form via bifurcated hydrogen bonding between polyol components (e.g., quebrachitol) and end‐functionalized polyisoprene chains, serving as effective crystallization

Analysis of radioactivity concentration in natural rubber latex and radiation prevulcanized natural rubber latex (RVNRL)

IOP Conference Series: Materials Science and Engineering, 2021
Abstract Radiation vulcanization of natural rubber latex (RVNRL) is an alternative technology to conventional sulphur vulcanization. To eliminate some public members sceptical view toward the radioactivity of the prevulcanized latex produced using gamma radiation, RVNRL was prepared at several radiation doses and then their radioactivity
