Freezing performance of selective artificial ground freezing based on three-pipe structure and its influencing analysis

Selective artificial ground freezing (S-AGF) enables directional cooling and mitigates unnecessary thermal loss through air-insulated casings, thereby exhibiting superior energy-saving and stratum-protection performance relative to conventional artificial ground freezing (C-AGF)....

Proton-Exchange Surface Engineering Enables Air-Stable Sodium Layered Oxide Cathodes for Carbon-Neutral Energy Storage

O3-type layered oxides have emerged as one of the most promising cathode candidates for sodium-ion batteries, which are widely regarded as a key enabling technology for carbon-neutral grid-scale energy storage. However, their practical application is hindered by surface degradati...

Characteristics and Mechanism of Water Vapour Resources in the Northern Slope of Kunlun Mountains

ABSTRACT Atmospheric water resources in the northern slope of Kunlun Mountains (NKM) are a crucial limiting factor for regional economic development and ecological security. Consequently, it is urgent to accurately assess the atmospheric water vapour and potential mechanisms in N...

The ecology of insolvency: Why the same legal framework produces different outcomes in China's cross‐border restructurings

Abstract The cross‐border insolvency interaction between Hong Kong and Mainland China represents a rare and unusually well‐documented example of sustained cooperation—and recurring friction—between a common law jurisdiction and a civil law jurisdiction operating within a single s...

A Grid-Forming Control Strategy Based on a Hybrid Approach Combining a Physical Model and LSTM for Photovoltaic and Energy Storage Systems

Traditional grid-forming converter (GFC) control faces fundamental challenges in maintaining DC bus stability during rapid power transients, primarily due to the limited dynamic response capability of source-side energy storage devices. To address this, this paper proposes a hybr...
