Active Thermal Field Integration for Marangoni‐Driven Salt Rejection and Water Collection

Advanced Functional Materials, EarlyView.
A thermal gradient fabric (TGF) evaporator with an auxiliary active thermal field can simultaneously increase evaporation rates and achieve long‐term salt rejection. The auxiliary active thermal field is well integrated with solar energy to construct moderate, extensive, and circulating Marangoni flow for salt rejection.

Study of an Elastic Electric Power and Energy Balance Strategy for Distribution Networks Considering Generalized Loads

Zhejiang dianli, 2022
The large-scale access of generalized loads to distribution networks makes load sources on the user side a carrier of both load and power supply. It is a trend for distribution planning and research to build a new elastic balance. This paper proposes an elastic electric power and energy balance strategy for distribution networks considering generalized

Predictive Control for Energy Management in Ship Power Systems under High-power Ramp Rate Loads [PDF]

arXiv, 2017
Electrical weapons and combat systems integrated into ships create challenges for their power systems. The main challenge is operation under high-power ramp rate loads, such as rail-guns and radar systems. When operated, these load devices may exceed the ships generators in terms of power ramp rate, which may drive the system to instability.

Elucidating Sodium Ion Storage Mechanisms in Hard Carbon Anodes at the Electronic Level

Advanced Functional Materials, EarlyView.
High‐resolution, multi‐frequency continuous wave, and pulsed Electron Paramagnetic Resonance (EPR) spectroscopy uncover the intricate Na ion storage mechanisms in hard carbon. This study reveals the coexistence of Na ion intercalation and solvent co‐intercalation, alongside a subsequent transition of Na ions from ionic to quasi‐metallic to metallic ...
