Researchers developed a terbium(III) complex with salicylic acid hydrazide that produced predominantly green luminescence and was tested for anti-counterfeiting inks, latent fingerprint visualization, and several laboratory bioactivity measures. Under the study conditions, the material showed durable visible luminescence, resolved fingerprint details across varied surfaces, and produced preliminary antioxidant, antimicrobial, cytotoxic, and a-glucosidase-inhibitory results that require further validation.
Xianglan Bai illustrates her development of biobased carbon fiber with two beakers in researchers' hands.
Researchers developed a pre-embedded solid-solid redox mediation strategy that mixes sulfur and iodine at the nanoscale inside mesoporous carbon to accelerate sulfur conversion in all-solid-state lithium-sulfur batteries. The iodine redox chemistry enabled fast charging, long cycle life, and strong performance at higher active-material loadings across several sulfide solid electrolytes.
A new $2.7 million industry-led project will help establish the sovereign capability Australia needs to manufacture critical metal components for defense, maritime and medical applications.
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.
Quantum information systems could one day shape everyday life through faster computing, sharper sensing and more secure communication.
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.
Researchers used a hierarchical machine learning strategy to identify tungsten bronze oxides and guide bismuth and germanium substitutions that improved permittivity and thermal stability. The resulting Ba4(Nd0.5Bi0.5)9.33(Ti0.99Ge0.01)18O54 ceramic combined high permittivity, very low dielectric loss, and near-zero temperature dependence, and was used to make compact prototype chip capacitors.
Researchers engineered lead-free BCZT/STO superlattice capacitors that achieved a recoverable energy storage density of 12.6 J/cm³ with near-99 % efficiency at 920 kV/cm, while maintaining stable performance through 2 × 108 charge–discharge cycles. Atomic-scale measurements indicate that the superlattice changes the size and spatial organization of polar nanoregions, while a strain-gradient-related internal field also contributes to the observed energy-storage behavior.
A research team led by Professor Ji-Sang Park of the Sungkyunkwan University, SKKU Advanced Institute of Nanotechnology (SAINT), in collaboration with Professor Yong-Young Noh's team at Pohang University of Science and Technology (POSTECH) and the teams of Professors Ao Liu and Huihui Zhu at the University of Electronic Science and Technology of China (UESTC), has successfully overcome the critical oxidation problem of conventional eco-friendly, lead-free perovskite semiconductors and developed a p-type transistor with world-class performance.
