Scalable Polyelectrolyte Complex‐Based Sorbent With Hourly Sorption−Desorption Cycles for Multicyclic Atmospheric Water Harvesting in Arid Environments

Advanced Functional Materials, EarlyView.
A polyelectrolyte complex‐based sorbent is produced by scalable, environmentally benign aqueous phase inversion. Its porous, LiCl‐ and GO‐integrated architecture enables hourly adsorption−desorption cycles at low relative humidity (RH < 30%). A large‐scale prototype achieves multicyclic, solar‐driven atmospheric water harvesting of 1.37 L kg−1 day−1 ...

Dynamic interaction analysis of grid-following and grid-forming hybrid system based on phase angle response

International Journal of Electrical Power & Energy Systems
Grid-following (GFL) converters potentially reduce the inertia and damping of the power system, thereby weakening the grid. Deploying grid-forming (GFM) converters can effectively enhance grid strength and improve system dynamic performance. However, due

Smooth switching control method for grid-following and grid-forming converters

Journal of Physics: Conference Series
Abstract In the end grid with high penetration of new energy, a single control mode of grid-following or grid-forming makes it difficult to balance stability, economy, and grid-supporting capabilities. To solve the above problems, starting from the topological structures and mathematical models of grid-following and grid-forming ...

Bioinspired Stabilization of Fluorescent Au@SiO2 Tracers for Multimodal Biological Imaging

Advanced Functional Materials, EarlyView.
This study demonstrates a bioinspired stabilization strategy for fluorescent gold‐silica nanoparticles. Inspired by natural biosilica maturation, high‐temperature calcination transforms the silica shells, preventing dissolution in cell culture media and intracellular environments.

Megawatt-level converter grid-forming control technology by adopting MPC for medium voltage distribution network

Frontiers in Energy Research
The grid-forming control (GFM) is treated as controlled voltage sources, which can enhance synchronize stability in weak grid case. However, the dynamic response of existing GFM method is limited, and the transient overcurrent in fault is still not ...

Design of a High-Performance High-Pass Generalized Integrator Based Single-Phase PLL

, 2016
Grid-interactive power converters are normally synchronized to the grid using phase-locked loops (PLLs). The performance of the PLLs is affected by the non-ideal conditions in the sensed grid voltage such as harmonics, frequency deviations and dc offsets

4D‐Printed Magneto‐Plasmonic Microrobots for Programmable Spatiotemporal De‐Icing

Advanced Functional Materials, EarlyView.
A 4D‐printing strategy is introduced to achieve programmable de‐icing devices. By aligning gold–magnetite nanofillers within a photosensitive resin, the printed structures exhibit dual magnetic and plasmonic functionalities, enabling precise spatio‐temporal ice removal through thermoplasmonic effects.

Stability analysis of grid-following converter considering DC side dynamics

电力工程技术
DC side dynamics are ignored in most of the research on grid-connected converter, which is dealt as a constant voltage source. In this case, the analysis result of small-signal stability is affected to some extent. In this paper, the impedance model of grid-following converter is reconstructed, then followed by stability analysis of the system ...
