Deformation and Failure Mechanisms of Natural/Waste Rubber Blends Under Mechanical and Thermal Cycles: A Synchrotron In Situ Study [PDF]
Macromolecular Rapid Communications, Volume 46, Issue 21, November 6, 2025.This study explores how ground tire rubber (GTR) enhances strain‐induced crystallization (SIC) in natural rubber (NR) under mechanical and thermal cycles. Using in situ WAXD, it reveals improved reinforcement, delayed failure, and increased thermal resistance while increasing GTR content.

Computer-assisted initial diagnosis of rare diseases [PDF]
PeerJ, 2016 Introduction. Most documented rare diseases have genetic origin. Because of their low individual frequency, an initial diagnosis based on phenotypic symptoms is not always easy, as practitioners might never have been exposed to patients suffering from ...

Journal of Applied Polymer Science, Volume 139, Issue 41, November 5, 2022., 2022 Abstract PLA/natural rubber (NR)/wastes tire rubber (GTR) were dynamically vulcanizing using dicumyl peroxide (DCP). Swelling, dissolution, and electron microscopy revealed that the unvulcanized and weekly vulcanized blends (DCP < 3 wt%) show a continuous rubber phase while the highly vulcanized blends (DCP > 3 wt%) show co‐continuous rubber/PLA phase.

Journal of Applied Polymer Science, Volume 139, Issue 23, June 15, 2022., 2022 The strain‐rate dependence for an ABS and a PMMA polymer have been analyzed in both compression and tension to determine hydrostatic pressure‐dependence. For ABS, a yield criterion has been compared to finite element simulations using the EGP model. Both methods give quantitatively similar results for yield stress prediction, but only the FE model is ...

Ultrathin Wide‐Bandgap a‐Si:H‐Based Solar Cells for Transparent Photovoltaic Applications
Solar RRL, Volume 6, Issue 1, January 2022., 2022 Ultrathin a‐Si:H/oxide transparent solar cells are reported. The use of oxide‐based carrier selective contacts and the effect of varying thickness of a‐Si:H films on the transparent photovoltaic properties of the devices, namely Average Visible Transmittance (AVT), Power Conversion Efficiency (PCE) and Light Utilization Efficiency (LUE) is studied.

The role of public administrations in promoting open municipal markets
Urban Agriculture &Regional Food Systems, Volume 7, Issue 1, 2022., 2022 Abstract Agroecological transitions require steps to be taken to shorten food circuits that prioritize local food markets and their social dimension. Such a measure would include open municipal markets (OMMs) because of their role in promoting the social nature of the agroecological transitions.

Reinforcement Learning with Probabilistic Boolean Network Models of Smart Grid Devices
Complexity, Volume 2022, Issue 1, 2022., 2022 The area of smart power grids needs to constantly improve its efficiency and resilience, to provide high quality electrical power in a resilient grid, while managing faults and avoiding failures. Achieving this requires high component reliability, adequate maintenance, and a studied failure occurrence. Correct system operation involves those activities
