Self-supported NiTe@NiMo electrodes enabling efficient sulfion oxidation reaction toward energy-saving and chlorine-free hybrid seawater electrolysis at high current densities The sulfion oxidation reaction (SOR) assisted seawater electrolysis has been proposed to be a potentially cost-effective approach to hydrogen production because SOR happens at an anodic potential significantly lower than that of the energy-demanding oxygen evolution reaction (OER).

Hydroxyl radicals (·OH) are important reactive oxygen species in environmental chemistry. The most efficient way to generate them is through a single-electron water-oxidation step, but this light-driven process is inefficient over inorganic semiconductor materials. Now, a judiciously designed polymeric carbon nitride has demonstrated high photocatalytic efficiency.

AbstractThe exponential growth of various complex images is putting tremendous pressure on storage systems. Here, we propose a memristor-based storage system with an integrated near-storage in-memory computing-based convolutional autoencoder compression network to boost the energy efficiency and speed of the image compression/retrieval and improve the storage density. We adopt the 4-bit memristor arrays to experimentally demonstrate the functions of the system.

Seawater electrolysis (SWE) is a promising and potentially cost-effective approach to hydrogen production, considering that seawater is vastly abundant and SWE is able to combine with offshore renewables producing green hydrogen that can be readily shipped by sea to end users. However, SWE has long been suffering from technical challenges including mainly the high energy demand and the interference of chlorine chemistry, leading electrolyzers to a low efficiency and short lifespan.
