Xianglan Bai illustrates her development of biobased carbon fiber with two beakers in researchers' hands.
Advanced plastic materials are increasingly recognized as one of the key enabling technologies for addressing the challenges of competitiveness, sustainability and industrial autonomy across strategic sectors.
Researchers developed an entirely rare-earth-free regenerator system for 4 K Gifford-McMahon cryocoolers by combining MnNb2-xTaxO6 with CuFe1-xAlxO2 to exploit their complementary low-temperature heat capacities. The best configuration delivered 0.163 W at 4.2 K, about 40% more cooling capacity than the CFAO-based regenerator and 73% of the performance of benchmark HoCu2 under equivalent conditions.
Researchers developed an n-type, scaffolded Si–ZnxMg1-xO photocatalyst that produced hydrogen from water without sacrificial electron donors under 100 W tungsten-lamp irradiation. By tuning the Zn/Mg ratio and associated defect states, the best-performing Si–Zn0.3Mg0.7O composition reached a hydrogen evolution rate of 1,954 µmol h?¹ cm?² and an apparent quantum yield of 36.47% at 600 nm.
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.
