Synergistic Intra‐ and Inter‐Nanozyme Electron Transfer through Interfacial Assembly for Enhanced Multi‐Enzyme Activity

Advanced Science, EarlyView.
A novel Prussian blue‐based composite nanoenzymes (PB C‐NZs)‐MoS2/PB, was designed based on the electron transfer mechanism and transport pathway. The structure uses MoS2 as the substrate, with PB grown on its surface through a surface assembly method.

Three-Dimensional Numerical Simulation of Gas–Liquid Two-Phase Flow in the Izena Hole, Middle Okinawa Trough, to Clarify the Generation Process of Seafloor Hydrothermal Deposits

Journal of MMIJ
Although seafloor hydrothermal deposits are essential metal resources because of their considerable reserves and high metal grades, the concrete physical setting that causes their generation remains unclear.

Impact of geothermal heating on the global ocean circulation [PDF]

, 2001
The response of a global circulation model to a uniform geothermal heat flux of 50 mW m-2 through the sea floor is examined. If the geothermal heat input were transported upward purely by diffusion, the deep ocean would warm by 1.2°C. However, geothermal

Decoding Short‐Range Order in Amorphous Two‐Dimensional Nanosheets for Efficient and Durable Ampere‐Level Seawater Electrolysis: A Case Study of Amorphous Ni(OH)2

Advanced Energy Materials, EarlyView.
This work uncovers the atomic‐scale origins of exceptional HER performance in amorphous Ni(OH)2 nanosheets by combining atom probe tomography, DFT simulations, and operando spectroscopy. We identify distinct short‐range‐order motifs that accelerate water dissociation, proton transport, and hydrogen adsorption. Embedding Pt single atoms further enhances

The subseafloor crustal biosphere: Ocean’s hidden biogeochemical reactor

Frontiers in Microbiology
Underlying the thick sediment layer in ocean basins, the flow of seawater through the cracked and porous upper igneous crust supports a previously hidden and largely unexplored active subsurface microbial biome.

Structural and hydrogeological features of a Lias carbonate aquifer in the Triffa Plain, NE Morocco [PDF]

, 2012
The rising demand for water and the contamination of shallow water table aquifers has led authorities in NE Morocco to look for deeper groundwater resources in the Triffa Plain, namely in Lower Jurassic (Lias) dolomitic limestones. The liassic aquifer is

From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,
