Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.Abstract The storage/release of freshwater in the Beaufort region has changed rapidly since the early 2000s. Using a suite of coupled ocean‐sea ice Nucleus for European Modeling of the Ocean (NEMO) model simulations with different configurations, resolutions, versions of sea ice module, and atmospheric and runoff forcings, we review hydrographic ...

A Control Strategy for Variable Speed Condenser Based on Doubly‐Fed Machine
IET Smart Energy Systems, Volume 2, Issue 2, Page 120-130, June 2026.This paper proposes a variable speed condenser (VSC) control strategy based on a doubly fed machine. It can be installed in PV stations and wind farms to enhance the grid‐connection performance of renewable energy power plants. ABSTRACT The lack of active power support capability in power systems with large‐scale renewable energy integration has become

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.ABSTRACT Conductive pitch‐based porous carbon materials were synthesized and systematically investigated as high‐performance electrode materials for supercapacitors. Petroleum‐derived pitch was thermally treated and chemically activated using KOH and NaOH at different pitch: activating agent molar ratio (1:1, 1:2, and 1:4) to optimize the pore ...

Battery Energy, Volume 5, Issue 3, May 2026.Conventional battery energy storage system models assume constant efficiencies, overlooking key physical limitations. This work introduces an analytical model with realistic state‐of‐charge (SOC)‐dependent efficiencies and charge acceptance, predicting that system operation concentrates in intermediate SOC ranges—a critical, overlooked behaviour ...
