A bioinspired bead-on-string Ag/AgCl heterostructure for stable ion-electron transduction in stretchable dry electrodes is developed, opening a route to long-term, high-fidelity wearable electrophysiological monitoring and personalized hands-free human-machine interaction.

This work develops an asymmetric polarization strategy for covalent triazine frameworks (CTFs) by introducing naphthalene units to strengthen the internal electric field and promote charge separation. The resulting CTF-P1 achieves an H₂O₂ production rate of 2762.0 μmol g⁻¹ h⁻¹ in pure water without sacrificial agents. Mechanistic studies reveal that enhanced polarization facilitates both oxygen reduction and water oxidation, enabling efficient photocatalytic H₂O₂ synthesis.

Under the dual challenges of global climate change and food security, agricultural environmental monitoring is at a critical juncture of transitioning from “passive remediation after the event” to “proactive prevention and control in advance.” With the development of smart agriculture, although mobile robots and multimodal sensors have addressed the problems of low efficiency and high cost in traditional manual sampling, most existing monitoring solutions remain at the “post-event detection” stage—that is, pollution has already occurred before an alarm finally arrives, causing control measures to often lag behind. To truly achieve green and sustainable agricultural development, there is an urgent need to give mobile robots a “smart brain”, enabling them not only to perceive the present but also to accurately predict the dynamic trends of pollutants based on complex environmental data.

This study proposes a novel Alamouti-Orthogonal Frequency Division Multiplexing (OFDM) system that mitigates constructive and destructive interference in practical multi-antenna wireless communications. Experimental results across multiple scenarios demonstrate that, under spatial misalignment, the Alamouti-OFDM system provides a maximum Signal-to-Noise Ratio (SNR) gain of 3.45 dB over traditional diversity transmission systems; in scenarios where traditional methods exhibit  > 10 dB spectral fluctuations, our system confines the spectral variations of the received signals within 2 dB.

A new study examines how limited parking affects electric vehicle commuters and shows that parking permit schemes can reduce inefficient competition for spaces. By modelling commuting, charging and parking decisions across multiple travel corridors, the researchers find that carefully designed permit allocation can lower system-wide travel costs while revealing important trade-offs between efficiency and equity.

Anyone buying a new smartphone usually wants to transfer their data from their old device quickly and easily. However, moving the digital contents of their phone is often more dangerous than people realise, as researchers at TU Graz have shown.
