Chitosan‐Graft‐Gelatin Hydrogel Containing Bromothymol Blue as a Food Spoilage Indicator for Intelligent Food Packaging

open access: yesAdvanced Materials Interfaces, EarlyView.
A chitosan‐graft‐gelatin hydrogel, incorporating a pH‐responsive dye, bromothymol blue, as a colorimetric freshness indicator is introduced to monitor the spoilage of chicken breasts. The hydrogel indicates microbial activity, and the production of carbon dioxide due to deteriorating food freshness via a change in pH, and serves as a smart and visual ...

Elastomeric Nanocomposite with Solvent‐Free, One Step, In Situ Shear Exfoliation of Graphite to Graphene

open access: yesAdvanced Materials Interfaces, EarlyView.
This work presents a novel strategy for nanocomposite fabrication that imparts high shear and elongational forces, overcoming the interlayer van der Waals forces within bulk 2D materials and facilitating their exfoliation in elastomers. Additionally, the high shear forces promote effective nanoparticle dispersion and in situ bond formation, leading to ...

Non-Invasive Monitoring of Vital Signs in Calves Using Thermal Imaging Technology [PDF]

open access: yesarXiv
This study presents a non-invasive method using thermal imaging to estimate heart and respiration rates in calves, avoiding the stress from wearables. Using Kernelised Correlation Filters (KCF) for movement tracking and advanced signal processing, we targeted one ROI for respiration and four for heart rate based on their thermal correlation.
