Uranium monitoring is essential for managing nuclear materials and assessing contamination in aquatic environments.
As wireless devices and high-frequency electronics become more widespread, materials that prevent electromagnetic interference are increasingly important. Many conductive shields work primarily by reflecting incoming waves, which can create unwanted secondary radiation. Polymer composites offer a lightweight and versatile alternative, and biochar provides a renewable source of conductive carbon.
An innovation company is turning waste milk proteins into high-value sustainable materials thanks to a collaboration with SRUC through the UK Research and Innovation (UKRI)-funded Digital Dairy Chain program.
The United States is working to reduce its reliance on petroleum-based aviation fuel by increasing the use of sustainable aviation fuel derived from renewable resources by 2050. A Rowan University research team is studying ways to produce these fuels.
Researchers synthesized Al-substituted Na5FeS4 positive electrode materials for all-solid-state sodium batteries and found that slight aluminum substitution increased apparent sodium-ion transport while preserving high capacity. Na5Fe0.95Al0.05S4 delivered about 500 mAh g-1 in initial testing, maintained more than 460 mAh g-1 for over 70 cycles, and showed reversible sulfur-related structural changes during cycling.
Researchers converted lignocellulosic pulp recovered from unrecyclable household waste, along with its post-hydrolysis residue, into reinforcements for biodegradable poly(L-lactide) composites. At 30 wt% loading, both waste-derived materials increased PLLA stiffness to about 6 GPa and accelerated disintegration under simulated industrial composting conditions.
Researchers used machine learning-assisted laser-induced breakdown spectroscopy (LIBS) to classify PP, PET, HDPE, and LDPE under three laser-energy conditions designed to mimic variations in laser irradiance, training the models on standard plastics and testing them on physically separate real-waste specimens. Combining preprocessing with wavelength selection raised the best test accuracy from 0.617 to 1.00, although that result was based on repeated measurements of only four held-out waste specimens, one per polymer class.
Commercial cameras can be powerful, producing images with exquisite details that mimic real life. In the lab, specially designed cameras can photograph objects in the infrared region, invisible to the naked eye.
Every summer, fires once again highlight the importance of solutions that can help minimize their consequences.
A research team led by Professor Boseok Kang of the SKKU Advanced Institute of Nanotechnology (SAINT), Department of Nano Engineering, and Department of Semiconductor Convergence Engineering has raised the doping efficiency of electrically conductive plastics (conducting polymers) to a world-class level by attaching specific molecules to them, and has for the first time elucidated the underlying operating mechanism.
