Microbial population dynamics in rubber coagula from Hevea brasiliensis [PDF]

, 2013
Natural rubber produced from the tree Hevea brasiliensis is a material of first importance for the tyre industry and for many other sectors such as the vibration isolation and the general rubber good industries. To produce TSR10 or 20 block rubber, trees

Natural Rubber Latex Aeroallergen Exposure [PDF]

The Annals of Occupational Hygiene, 2002
We read with interest the account by Sri-Akajunt et al. (2000) of their measurement of personal exposure to latex airborne allergens in three occupational exposure groups. We were, however, surprised to note that in citing Swanson et al. (1994) and Liss et al. (1997) they misquoted the units of exposure. Swanson recorded a range of 8–978 ng/m3; this is

Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents

Polymer International, EarlyView.
The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐

Environmentally safe preservation and stabilization of natural rubber latex in an acidic environment

SPE Polymers, 2023
Natural rubber is an indispensable raw material that supplies about half of the world's rubber consumption. The latex that is extracted from the trees is composed of polyisoprene rubber, proteins, sugars, amino acids, lipids, and minerals.

Connecting tradition and technology: The digitization of the ethnobotanical collection at the Rio de Janeiro Botanical Garden

PLANTS, PEOPLE, PLANET, EarlyView.
The digitization of RBetno (JBRJ) represents a step forward for biodiversity conservation in Brazil. Aligned with the Kunming‐Montreal Global Biodiversity Framework (Target 2, 2020–2030), this project documents the use of plants, including traditional knowledge and vernacular names, with a focus on the Atlantic Forest and Amazon.

Transcript Profiling of Hevea brasiliensis during Latex Flow

Frontiers in Plant Science, 2017
Latex exploitation enhances latex regeneration in rubber trees. The latex exploitation-caused latex flow lasts from 10 min to a few hours, which is convenient for exploring the transcript profiling of latex metabolism-related genes at the different ...

Latex allergy in dentistry: clinical cases report [PDF]

, 2010
Generally natural rubber latex (NRL) allergy is detected after some exposition to the material. As NRL is com- monly found in different materials used daily in dental clinic, the allergy can be manifested in the pediatric dentistry ...

Ageing of Natural Rubber under Stress

, 2000
We report a dynamical-mechanical study of stress relaxation at small deformation in a natural (polyisoprene) rubber well above its glass transition temperature Tg. We find that an almost complete relaxation of stress takes place over very long periods of

Hevea brasiliensis seeds: A novel sustainable feedstock for ethanol production

Vietnam Journal of Chemistry, EarlyView.
Abstract The rubber tree (Hevea brasiliensis) is cultivated on a large scale mainly for the extraction of latex in Brazil and Southeast Asia, also generating large quantities of seeds. These seeds currently do not have large‐scale applications and may thus be considered as a residue.
