However, a lack of advanced modular design strategies for complex systems has hindered progress in mechanical computing. This study introduces a top-down design approach to non-volatile logic mechanical computing using multi-output logic gates designed with square lattices and bistable beams, addressing functional scalability through a modular design that facilitates the assembly of mechanical circuits.

Specifically, cubic perovskite materials exhibit significant MO effects in the visible light band. It is found that heavy element bismuth (Bi)-doped MAPbBr3 can enhance spin-orbit coupling effects and generate defect energy levels. Essentially, this doping increases the probability of electronic transitions and alters the energy of electronic transitions, thereby enhancing the MO effect of perovskite. Here, the optimization approach is investigated for perovskite MO materials and prepare methylammonium lead bromide (MAPbBr3) films doped with varying concentrations of Bi ranging from 1–20% using the spray method. The experimental results of the Faraday rotation angle indicate that the 1% Bi-doped MAPbBr3 film achieved a 61.3% performance improvement compared to the MO material terbium gallium garnet material at a wavelength of 650 nm.

However, realizing the full potential of 2D materials in industrial applications requires overcoming challenges in fabricating scalable and CMOS-compatible devices, particularly concerning metal-semiconductor contacts. Here, a hybrid-contact configuration is presented by developing a hard-mask scanning probe lithography (SPL) for high-performance molybdenum disulfide (MoS2) field-effect transistors (FETs). After systematically comparing with the fabricated top-contact and edge-contact configurations, the hybrid-contact substantially improves carrier injection efficiency, enabling an enhanced on-current of 50.5 µA·µm⁻¹, an on/off ratio exceeding 5 × 1010, a reduced contact resistance of 2.14 kΩ·µm, and a Schottky barrier height of 26 meV, which is evidently illustrated by using the equivalent resistor network. The hard-mask SPL also facilitates the high-resolution nanoscale patterning on MoS2 flakes with a feature size of ≈18 nm.

This study introduces a gravity-switch-triggered triboelectric nanogenerator (GS-TENG) designed to enhance the efficiency of wave energy collection. The GS-TENG uses a gravity switch to control circuit connections and disconnections, optimizing the internal structure and experimentally adjusting the number of nylon balls to enhance output performance. In experiments, the GS-TENG demonstrated adaptability to various wave directions and achieved a short-circuit current of 22.2 µA, an open-circuit voltage of 196 V, and a transferred charge of 75 nC under specific conditions. This showcases its superior performance in low-frequency wave energy collection. Additionally, the device successfully lit 100 LEDs in a simulated wave environment, validating its potential for practical applications.

Density functional theory (DFT) calculations guide the experiments that reveal a homeotropic-to-planar transition in the LCs upon exposure to SARS-CoV-2 spike-decorated yeast, providing a basis for sensitive virus detection. The sensor's reversibility/specificity is confirmed through antibody-induced orientation recovery of the LCs initial orientation. Strikingly, the sensor can detect ≈2000 copies of the spike protein per mL, which is well below the typical concentration of the virus in the saliva of an infected human (104 copies per mL)- revealing the practical applicability of the sensor.

Three electrode designs (double, top, bottom) are evaluated, revealing that the double-electrode configuration delivers the highest output. This enhanced performance arises from synergistic droplet motion, electrical double-layer formation, and charge discharge, as validated by an equivalent circuit model. By varying droplet heights from 1–20 cm, volumes of 7.7–50 µL, flow rates of 50–300 drops/min, and tilt angles of 0–90°, an optimized setup yields −70 V and 22 mA, translating to a power density of 0.28 µW cm−2. High-speed imaging correlates these outputs with droplet impact dynamics and the resulting charge transfer. Additionally, the optimized DEG can power small electronic devices, charge capacitors, and monitor artificial acid rain in real-time, displaying distinct electrical signals compared to typical rainwater.

Here, a low environment-dependent, portable, high-speed multi-material electrospinning device (LEPHE) is proposed based on a gas-electric coupling field. With an internal electric field and airfield, LEPHE can decouple the electrospinning process into two stages: jet formation and delivery. This design eliminates the effects of environmental factors on film formation, which are common challenges in traditional electrospinning. By utilizing a multi-needle gas-electric coupling field head with alternating bifurcated channels inside, LEPHE significantly improves efficiency and allows for in situ composite film preparation. Experimental results demonstrate the system's excellent environment adaptability, high spinning efficiency, and good uniformity in film formation. Additionally, LEPHE is capable of achieving uniformly mixed deposition of multi-material fibers.
