Piezoresistive Natural Rubber Composites: A Comparison Between Low‐Temperature Glutaraldehyde Curing Agents and Conventional Sulfur Curing Systems

open access: yesPolymer Composites, Volume 47, Issue 5, Page 4310-4325, 10 March 2026.
The secondary electrical signal peak during cyclic experiment observed in S‐cured NR sensors was eliminated with GA curing due to the homogeneous distribution of crosslink points in the GA‐cured NR network. ABSTRACT This study examines the piezoresistive behavior of natural rubber (NR) composites cured with sulfur (S) and glutaraldehyde (GA) and ...

Some considerations concerning the panel management in rubber tapping (Hevea brasiliensis) [PDF]

open access: yes, 2006
Research devoted to long term panel management deserved less efforts, mainly due to the long duration required for experimentation. The present study deals with the comparison of two panel management strategies on nine clones tapped in 1/2S, over a total

Molecular mechanisms associated with rootstock–scion interactions in rubber trees

open access: yesThe Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Hevea brasiliensis (rubber tree) is the main source of natural rubber worldwide. In commercial plantations, high‐yield rubber tree clones are propagated by grafting onto seedling rootstocks. In this study, the transcriptomes of the RRIM 600 clone grafted on different rootstocks in southeastern Brazil were evaluated. Exclusively expressed genes

Desempenho do método de dissipação térmica na medida do fluxo de seiva em seringueira Performance of a thermal dissipation method for sap flow measurement in rubber tree

open access: yesEngenharia Agrícola, 2006
A medida da transpiração de árvores no campo é de difícil consecução. Nas duas últimas décadas, tem-se dado ênfase à medida de fluxo de seiva no caule como indicador da transpiração, principalmente se a escala de tempo usada é igual ou menor que um dia ...
