From leather wastes to leather: enhancement of low quality leather using collagen recovered from leather tanned wastes

Clean Technologies and Environmental Policy, 2023
AbstractLeather industry produces huge amounts of solid wastes. In the last decade, several methods for the recovery and valorization of these wastes were developed, mainly focused on the extraction of collagen using chemical methods. The extracted collagen, due to its poor quality, is mostly used in agriculture as a nitrogen source ingredient of ...

Extreme‐Temperature Resistant, Flexible, and Sensitive Strain Sensor for Aerospace Parachute Deployment

Advanced Materials Technologies, EarlyView.
In this study, we report a resistive‐type strain sensor fabricated using single‐walled CNTs, are used layer using the pray technique to deposit as conductive, and UV‐resin was spin‐coated as a protection layer. The sensor functioned in harsh temperature variation conditions from −50°C to 125°C without deterioration.

Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites

Advanced Materials Technologies, EarlyView.
Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.
