Brain-inspired acoustic-optical system recognizes voice commands and drone trajectories
Tsinghua University PressPeer-Reviewed Publication
Researchers at Ningbo University have developed a brain-inspired acoustic-optical information reservoir system that combines a self-powered triboelectric acoustic sensor with an indium-zinc-oxide photoelectronic neuromorphic transistor. The integrated system can sense sound and light, reproduce synaptic-like memory behaviors, and convert voice commands and drone trajectory images into high-dimensional conductance states. Combined with a multilayer perceptron classifier, the system achieved average testing accuracies of approximately 89.8% for nine voice commands and 93.6% for nine drone trajectories. The work provides a potential hardware platform for intelligent voice interaction, multimodal edge sensing and autonomous applications in the low-altitude economy.

Selective laser reduction uncovers why graphene oxide becomes more vulnerable to fatigue
Tsinghua University PressPeer-Reviewed Publication
Laser processing is widely used to “repair” and pattern graphene oxide for flexible electronics. Surprisingly, researchers found that laser treatment can shorten rather than improve the material’s fatigue lifetime. By combining Raman spectroscopy, nano-infrared imaging and atomic force microscopy, the team discovered that laser irradiation selectively removes epoxide groups while leaving behind vacancy defects, revealing the chemical origin of fatigue degradation.

Wafer-scale growth of ultrathin amorphous tellurium oxide via pulsed laser deposition for p-channel transistors
Tsinghua University PressPeer-Reviewed Publication
Oxide semiconductors are promising building blocks for complementary transparent electronics, and however p-type oxide semiconductors suffer from limited material choice and low carrier mobility as compared to their n-type counterparts. Herein, a wafer-scale growth of amorphous tellurium oxide (TeOx) thin films with p-type transport characteristics was demonstrated, through a pulsed laser deposition (PLD) method coupled with a low-temperature post-annealing treatment. Ultrathin TeOx with the thickness down to several nanometers is prepared by oxidizing the Te thin films precisely deposited and controlled by PLD technique, where their stoichiometric ratio can be modulated by the annealing time. Moreover, the optical bandgap of TeOx is found to be varied from 0.59 eV to 0.98 eV during the oxidation process. As a result, the TeOx-based field-effect transistors exhibit a competitive hole transport behavior as compared to reported amorphous TeOx, along with the current on/off ratio exceeding 2 × 103 (1.3 × 107) and hole mobility of 47.6 ± 2 cm2·V-1·s-1 (41.8 ± 0.5 cm2·V-1·s-1) at 300 K (80 K). These findings promise a facile and controllable approach to synthesize wafer-scale and ultrathin p-type oxides for future complementary electronics.

Surface hydrogen‑bonded network boosts plasma‑driven CO2 to C2H4 conversion
Tsinghua University PressPeer-Reviewed Publication
Non‑thermal plasma (NTP) offers a low‑temperature route for direct CO2 reduction using H2O as the hydrogen source, but the non‑selective reactivity of gaseous ·H and ·OH radicals often limits product selectivity. Now, researchers from Southwest University of Science and Technology have designed a CeHfZr metal‑organic framework that adsorbs H2O to form a surface hydrogen‑bonded network. Under NTP, this network generates solvated ·H and ·OH radicals in situ, achieving a C2H4 production rate of 164.6 μmol·g-1·h-1, 15 times higher than single‑metal Ce. The work provides a new catalyst design strategy for converting industrial CO2 exhaust into valuable C2H4.

Machine learning co-optimizes flexible carbon nanotube transistors for low-voltage logic
Tsinghua University PressPeer-Reviewed Publication
Flexible carbon nanotube thin-film transistors combine high carrier mobility, low-temperature fabrication and mechanical compliance, but reliable circuits require several tightly coupled electrical metrics to be optimized at the same time. Researchers at Peking University developed a machine-learning-guided framework that translates circuit-level targets into fabrication recipes, enabling 2 V ring oscillators, basic logic gates and a 1-bit full adder on flexible substrates.

Zn2+-doped Cs-Cu-I perovskite nanocrystals for white light-emitting diodes with high color rendering index
Tsinghua University PressPeer-Reviewed Publication
The rapid advancement of solid-state lighting technology has made white LEDs the preferred choice for energy-efficient illumination. Nevertheless, commercial white LEDs based on blue chips and yellow phosphors suffer from inadequate red components and poor spectral continuity, leading to low color rendering index (CRI). Lead-free Cs-Cu-I perovskites, with their unique self-trapped exciton (STE) emission, offer a promising single-component white-light platform, yet their low photoluminescence quantum yield (PLQY) remains a major obstacle. Therefore, enhancing both the PLQY and spectral coverage of Cs-Cu-I is critically important.
A team led by Aiwei Tang professor from Beijing Jiaotong University recently reported a Zn2+ doping strategy for Cs-Cu-I perovskite nanocrystals (NCs) to achieve high-CRI white LEDs, advancing eco-friendly solid-state lighting.

Synergistic effects in Pt-Pd binary electrocatalyst for efficient hydrogen peroxide electrosynthesis
Tsinghua University PressPeer-Reviewed Publication
Prof. Jun Bao’s team developed a synergistic PtPd-Al2O3 catalyst for highly selective (96%) and durable (>20 h, FE >80%) electrochemical H2O2 production via the 2e⁻ oxygen reduction pathway under neutral conditions. In-situ synchrotron and DFT studies revealed that Pd modulates Pt’s electronic structure, upshifts the d-band center, optimizes *OOH adsorption, and suppresses O–O cleavage, while also stabilizing the alloy structure during operation. This work offers a general strategy for designing stable noble-metal catalysts for various electrochemical transformations.

Achieving rigid-flexible coupling in polyimide aerogels via biomimetic cross-scale architecture for extreme condition protection
Tsinghua University PressPeer-Reviewed Publication
Extreme-environment protection requires lightweight materials that can simultaneously provide thermal insulation, mechanical resilience, and impact resistance. Inspired by the hierarchical structure of bamboo, researchers at Donghua University developed a biomimetic polyimide composite aerogel with cross-scale molecular crosslinking, nanofiber interlocking, and porous scaffold support, enabling rigid–flexible coupling and integrated thermo-mechanical protection for aerospace, firefighting, and other harsh-environment applications.
