Controlled alignment and patterning of individual semiconducting nanowires at a desired position in a large area is a key requirement for electronic device applications. High-speed, large-area printing of highly aligned individual nanowires that allows control of the exact numbers of wires, and their orientations and dimensions is a significant challenge for practical electronics applications. Here we use a high-speed electrohydrodynamic organic nanowire printer to print large-area organic semiconducting nanowire arrays directly on device substrates in a precisely, individually controlled manner; this method also enables sophisticated large-area nanowire lithography for nano-electronics. We achieve a maximum field-effect mobility up to 9.7 cm(2) V(-1) s(-1) with extremely low contact resistance (<5.53 Ω cm), even in nano-channel transistors based on single-stranded semiconducting nanowires. We also demonstrate complementary inverter circuit arrays comprising well-aligned p-type and n-type organic semiconducting nanowires. Extremely fast nanolithography using printed semiconducting nanowire arrays provide a simple, reliable method of fabricating large-area and flexible nano-electronics.

Natural seawater electrolysis is emerging as a desirable approach for hydrogen production, but it suffers from long-term instability due to severe chloride corrosion. In this study, Zr doped CoO is proposed for natural seawater oxidation, which requires an overpotential of only 570 mV to drive a current density of 100 mA cm, and a sustained natural seawater electrolysis at 10 mA cm for 500h exhibits only 0.78 % decay.

Cadmium sulfide is widely employed in environmental catalysis due to its excellent catalytic behaviors. However, the inherent toxicity and leaching risk of CdS-based catalyst presents significant challenges for practical applications. This study explored the incorporation of CdS nanowires on the nitrogen-doped multi-wall carbon tubes (N-MWCNTs) substrate to minimize the leaching rate and mitigate the bio-toxicity by regulating the electron transfer process.

Herein, cuprous oxide (CuO) nanowires are synthesized by a simple process, realizing the high selectivity electrocatalytic reductive amination of biomass-derived pyruvate to alanine (organic product selectivity: ∼100%). Importantly, a total of 8 different amino acids can be efficiently synthesized using CuO nanowires, confirming the universality of CuO nanowires.
