Summary: Organohydrides are important organic compounds that provide hydride anions for reactions, and their hydride transfer and regeneration play a crucial role in organohydride-catalyzed reduction reactions. In this study, different forms of BIH derivatives were synthesized and their photophysical and electrochemical properties were investigated. The 4-(dimethylamino)phenyl-substituted BIH showed red-shifted absorption and visible-light-driven regeneration without using an external photosensitizer. This has implications for the development of solar-energy-based catalytic photoreduction technologies.

Summary: This paper presents the design and characteristics of a three-chamber electromagnetic-driven peristaltic micropump based on 3D-printing technology. It includes an NdFeB permanent magnet, a polydimethylsiloxane (PDMS) film, a 3D-printing pump body, bolts, electromagnets, and a cantilever valve. Simulation analysis and experiments were conducted to optimize the results using single chamber and three chambers, with and without valves, and different starting modes. It is concluded that the performance of the three-chamber valved model is optimal under synchronous starting conditions. The maximum output flow and back pressure of the micropump system are 2407.2 μL/min and 1127 Pa, respectively, with a maximum specific flow and back pressure of 534.9 μL/min·W and 250.4 Pa/W, respectively.

Summary: Current collectors in batteries provide electron transport and support to electrode materials. Metal foils are commonly used as current collectors but do not contribute to energy storage. A new type of current collector made of 3D metallic glass-fiber fabrics (MGFs) is reported, which has advantages of lightweight, electrochemical stability, fire resistance, strength, and flexibility suitable for roll-to-roll electrode fabrication. By replacing metal foils with MGFs, the energy density of lithium batteries can be improved by 9-18%. Additionally, MGFs are suitable for flexible battery fabrication, as demonstrated by a high-energy-density flexible lithium battery.

Summary: Vat polymerization is widely used for additive manufacturing of micro-architected structures. This study investigates the influence of oxygen inhibition on the mechanical properties of structures made using this technique. The surface of the structures was found to be incompletely cured, leading to softer properties. Post-print curing in nitrogen improved stiffness compared to air, but oxygen during printing resulted in softer samples than nitrogen photocured samples. These results highlight the significant impact of oxygen inhibition on micro-architected structures realized using vat polymerization.

Summary: We propose a fabrication method for intrinsically stretchable organic electrochemical transistors (OECTs) by combining a microstructured hydrophilic substrate, multimaterial printing of functional inks, and optimization of device channel geometries. The resulting OECT array exhibits high transconductance (22.5 mS), excellent mechanical softness (Young's modulus similar to 2.2 MPa), and stretchability (similar to 30%). Moreover, the device demonstrates artificial synapse functionality, mimicking biological synapses with features such as paired-pulse depression, short-term plasticity, and long-term plasticity. This study provides a promising strategy for fabricating stretchable OECTs and offers valuable insights for the development of brain-computer interfaces.
