Researchers have developed a wide-field Fourier transform hyperspectral imaging system that captures electrochemical reactions on hundreds of individual nanoparticles simultaneously. By integrating a common-path interferometer with a fast 2D camera, the method provides real-time spectral evolution during electrodeposition of palladium and cadmium sulfide on gold nanoparticles. Statistical analysis reveals distinct deposition behaviors on nanospheres versus nanorods—insights that would require thousands of tedious single-particle measurements using conventional approaches.
Flexible terahertz devices are essential for wearable photonics and intelligent communication systems, yet mechanical deformation can cause information loss and signal interruption. Here, Te nanofilms grown on PET substrates are introduced as flexible all-optical terahertz modulators with high modulation efficiency, picosecond response, low insertion loss, and robust bending tolerance. The device further enables stable neural-network-based image recognition under different bending conditions, providing a route toward flexible intelligent terahertz optoelectronics.
Researchers have developed a compact, built-in neutron analyzer for on-site measurement of uranium loading and element changes in wet ion-exchange resins. The 80 kg system combines prompt fission-neutron counting with prompt-gamma spectroscopy. Laboratory tests yielded a 0.129 g/L uranium detection limit in 60 s, while a field campaign at a commercial in-situ recovery mine followed adsorption, elution, transformation and a second adsorption cycle.
A review by researchers from Shandong University and collaborating institutions argues that making virtual objects look real is no longer enough; the next advance in virtual reality (VR) and augmented reality (AR) will require making them feel real as well. Published in Materials Futures, the article proposes a closed-loop "human-machine-environment" haptic interaction framework that links tactile sensing, intelligent processing, and physical feedback into a single system for more realistic digital interaction.A review by researchers from Shandong University and collaborating institutions argues that making virtual objects look real is no longer enough; the next advance in virtual reality (VR) and augmented reality (AR) will require making them feel real as well.

A new review brings together research on geopolitical tensions, meteorological disasters, regional environmental degradation, supply chain disruption, systemic financial instability, and technology-mediated societal and institutional risks. It shows how shocks can spread through interconnected political, economic, ecological, technological, and social systems, and outlines a flexible cycle of risk identification, assessment, management, and adaptive monitoring supported by international cooperation.
Medical imaging datasets are essential for training artificial intelligence systems, but sharing brain magnetic resonance imaging (MRI) scans can expose patient-specific anatomical patterns. Anonymization must therefore do more than remove identifiers: it must make the overall image harder to link back to a patient while retaining the lesion information needed for segmentation and classification. Existing generative approaches often emphasize global image quality or facial de-identification, leaving lesion-centric utility and re-identification risk insufficiently addressed.
