Covalent Organic Frameworks for Water Sorption: The Importance of Framework Physical Stability
This study explores the water‐vapor stability of 2D covalent organic frameworks (COFs) with varying pore sizes. Results reveal microporous COFs demonstrate superior stability compared to mesoporous ones, despite lower water uptake. Mesoporous keto‐enamine‐linked COFs show enhanced stability due to intralayer hydrogen bonds, confirmed by simulations and

Multiband Switchable Microwave Absorbing Metamaterials Based on Reconfigurable Kirigami–Origami
A reconfigurable metamaterial featuring tunable microwave‐absorbing and load‐bearing performance is proposed. Stretchable kirigami and bistable origami configurations are integrated as actuating components, and the synergistic deformation mechanisms are systematically analyzed.

A modular multi-level DC-DC converter for HVDC grids
A double-T DC-DC modular multilevel converter (DC-DC-MMC) topology for high-voltage dc (HVdc) applications is presented in this paper. The topology is intended to interconnect large power dc grids with different voltage levels or to control the power flow in meshed dc grids. A two level control hierarchy is used to regulate the dc voltage of each cell.

Offshore wind energy is expected to have a steep grow in Europe due to increase demand for electricity originated from renewable sources. If the sector is to fulfil the expectations, Europe will have to install yearly circa 4.1 GW of offshore wind for the next ten years.

The highly anisotropic Fermi surface of bismuth results in variations in magnetotransport properties across different crystallographic directions, which can be characterized by studying microcrystals. To avoid the observed surface melting under room temperature Focused Ion Beam (FIB) irradiation, two low‐temperature FIB fabrication methods are proposed
