Functional Aerogel Fibers

In their Research Article (10.1002/admt.202501315), Mohammad Arjmand and co-workers report the synthesis of nature-inspired core–shell aerogel fibers using coaxial wet spinning, featuring a polyimide shell encapsulating a Ti₃C₂T_x MXene core. By optimizing the solvent-exchange process, they achieve hierarchical porosity, resulting in moisture-resistant, knittable, and flame-retardant fibers with a tensile strength of 20.4 MPa and an absorption-dominant electromagnetic interference shielding effectiveness of 54.9 dB.

Volumetric Additive Manufacturing

The cover displays micrographs of the pore structure obtained for parts produced by tomographic volumetric additive manufacturing with the foaming material developed in The Research Article (10.1002/admt.202501355) by Dorothea Helmer and co-workers. Expanding the printed parts via foaming allows to produce structures exceeding the print volume. The same part as-printed, foamed and shrunken shows very different structure and mechanical properties.

Perovskite Photodetectors

In their Research Article (10.1002/admt.202500932), Chih-Yu Chang and Abhisek Panda present an additive engineering strategy that leverages the synergistic effect of zwitterionic molecules within perovskite films. These molecules form cross-linked polymer networks, which concurrently passivate charged defects, enhance crystallinity, and improve the moisture resistance of perovskite films. Consequently, the highest reported performance for self-powered perovskite photodetectors and substantially improved device stability under high-humidity conditions are achieved simultaneously.

Ultrasound-Driven Triboelectric Nanogenerators

This cover illustrates the concept of an ultrasound-driven triboelectric nanogenerator for functional wireless power transfer. The flexible nanogenerator receives mechanical ultrasonic waves emitted from a transducer and converts them into electrical energy through triboelectric coupling. The generated energy wirelessly powers various applications, including battery-free biotherapeutic devices for neural modulation and wound healing, rechargeable implantable bioelectronics such as cardiovascular and neurostimulator devices, and underwater energy harvesting systems for communication and chemical production. More details can be found in the Research Article by Sunghoon Hur, Hyun-Cheol Song, and co-workers (10.1002/admt.202501606).

The implementation of adaptive multifunctional transistors is key to improving data processing capabilities and overcoming the scaling and power density limitations of conventional complementary metal-oxide-semiconductor (CMOS) technology. In this context, anti-ambipolar transistors (AATs) enabling negative differential transconductance (NDT) characteristics hold promise of enhancing the performance and functionality of computational systems by implementing multivalued logic (MVL). Here, we demonstrate a Si-based multi-functional run-time reconfigurable transistor with a distinct hysteresis-free AAT mode showing stable and reproducible NDT characteristics through precise carrier polarity control. The proposed multi-gate device exhibits a bias voltage-tunable room temperature peak-to-valley ratio (PVR) up to approximately 10⁷ and bias-independent ultra-low off-state currents below 50 fA, strongly surpassing the capabilities of state-of-the-art negative differential resistance (NDR) diodes and transistors. A detailed and systematic study of the NDT characteristic revealed stable device operation beyond 400 K. Most notably, the demonstration of NDT in a Si-based AAT FET may contribute to the co-integration of high-frequency doublers, spiking neuron circuits, and MVL alongside conventional CMOS technology.

Reconfigurable Metasurfaces

In their Research Article (10.1002/admt.202500789), Yan Shi, Long Li, and co-workers propose a method of staged controlled electromagnetic resonance to decouple the modulation processes for amplitude and phase. Using their VO₂-based metasurface, the decoupled modulation processes can be stage-triggered at different laser power levels. This work provides an interesting method for new multifunctional terahertz devices in the next-generation communication system.
