High‐Power Hybrid Nanogenerator With Multi‐Degree‐of‐Freedom Mechanical Coupling for Harvesting Water Wave Energy

Advanced Science, EarlyView.
A high‐power hybrid nanogenerator (HP‐HNG) with multi‐degree‐of‐freedom mechanical coupling is reported, integrating multi‐directional wave energy for output to achieve 1 + 1 > 2 energy harvesting. The HP‐HNG achieves a peak output power of 0.764 W, corresponding to a peak power density of 127.303 W m−3. At a wave frequency of 1 Hz, the HP‐HNG delivers

Characterization and bias correction of low-level jets at FINO1 using lidar observations and reanalysis data [PDF]

Wind Energy Science
Low-level jets (LLJs) are wind maxima typically observed within a few hundred meters of the surface. They are often associated with high vertical wind shear, which significantly impacts the performance and loading of modern wind turbines.

Electric Double Layer Engineering Induces O‐Down Interfacial Water Reorientation for Efficient and Long‐Term Seawater Electrolysis

Advanced Energy Materials, EarlyView.
The additive EDTMPS inhibits hydroxides deposition by chelating with Ca2+/Mg2+. It also disrupts the hydrogen bond network of interfacial water and expands the thickness of electric double layer, promoting more free water to flip into adsorbable O‐down configuration.
