Machine Learning Paradigm for Advanced Battery Electrolyte Development

Carbon Energy, EarlyView.
Electrolyte materials determine ion transport kinetics within the bulk and interphases, ultimately influencing the performance of battery systems. As data‐driven paradigms increasingly reshape materials discovery, this review provides an application‐oriented exploration of the intersection between machine learning and electrolyte science. By evaluating

Tunable amylopectin graft copolymers for flocculating and dewatering iron ore tailings

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Polyacrylamide (PAM), the standard flocculant for mining tailings, often produces turbid supernatants and poorly dewatered sediments, limiting water reuse and tailings densification. We synthesized amylopectin‐graft‐poly[(2‐methacryloyloxy)ethyl]trimethylammonium chloride (AP‐g‐PMETAC) copolymers with systematically varied graft frequency (N =

Research on diffusion characteristics of cutting turbulent dust in fully mechanized working face with large mining height

Meikuang Anquan
Taking Sandaogou Coal Mine 85219 fully mechanized coal mining face as an example, the dust migration rules of the front and rear cylinders under the influence of different cutting turbulent wind conditions were numerically simulated, and the effects of downwind and upwind cutting on the diffusion of turbulent dust on the working face were compared.

Study on Rib Spalling Mechanism and Spalling Depth in Large Mining Height Fully-Mechanized Face

, 2016
Due to the influence of the high intensity mining operation in the Shendong mining area located in Ordos City, Inner Mongolia Region of China, the problem of rib spalling in large mining height and fully-mechanized working face production is increasingly

Regulatory Convergence and Divergence in ESG Reporting in the Indo‐Pacific Region

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Environmental, social, and governance (ESG) reporting has evolved significantly globally over the past few decades. Many countries are now signatories to international agreements such as the United Nations Framework Convention on Climate Change (UNFCCC) and the Paris Agreement, with increasing commitments to emissions reduction targets and the

Review and prospects of shear test of bolted rock joints

Deep Underground Science and Engineering, EarlyView.
The laboratory shear test equipment, test method, and numerical simulation of bolted rock joints were summarized. The shortcomings and limitations of the current research were analyzed, and the research prospects were proposed. Abstract Rock bolting is a critical approach in geotechnical engineering for supporting weak rocks.

Failure characteristics analysis of the inclined interlayer during water‐soluble cavity construction of underground salt caverns for large‐scale energy storage

Deep Underground Science and Engineering, EarlyView.
In the process of water‐soluble cavern construction of salt cavern energy storage, since the interlayer does not dissolve in water easily, sudden collapse will cause engineering accidents such as bending and damage of the inner tube of the cavern.

A rock brittleness index based on the postpeak energy release rate and damage surface characteristics for brittle hard rock

Deep Underground Science and Engineering, EarlyView.
This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.
