Processability and Crosslink Density: Role of Peptizers in Natural Rubber and Chlorobutyl Rubber

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 22, June 10, 2026.
This work evaluates how chemical and physical peptizers affect mastication, vulcanization behavior, and network formation in natural rubber and chlorobutyl rubber. Size‐exclusion chromatography, rheometry, DSC, and swelling analyses demonstrate improved processability but reduced crosslink density with peptizer addition.

Characterization of Goat Milk Fermented With Streptococcus thermophilus, Limosilactobacillus mucosae CNPC007 and Inulin With Addition of Cereus jamacaru

open access: yesApplied Research, Volume 5, Issue 3, June 2026.
Limosilactobacillus mucosae maintained viability above 7 log CFU/g during storage of the fermented goat milk with inulin and Cereus jamacaru jam and survived over 4 log CFU/g during the in vitro gastrointestinal simulation. This jam enriched the total phenolic content of the fermented milk that achieved overall acceptability scores close to or above 7.

What's there beyond the sun and the sea? Detecting tourists' interest towards nature in a mass tourism destination using social media data

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1802-1816, June 2026.
Abstract Nature‐based tourism is a rapidly growing subsector of the international tourism industry. However, capturing broad‐scale patterns of nature visits during touristic trips or visitors' appreciation of nature may be difficult using traditional data sources and methods. In this study, we harness geotagged social media data to understand the scale
