Creep Properties of Mudstone Interlayer in Bedded Salt Rock Energy Storage Based on Multistage Creep Test: A Case Study of Huai’an Salt Mine, Jiangsu Province

Geofluids, 2022
Salt rock is internationally recognized as an excellent medium for energy storage. However, most of the domestic salt mines are lacustrine laminated formations with mudstone interlayers, which have different creep characteristics to pure salt rocks ...

Modified Nishihara Rheological Model considering the Effect of Thermal-Mechanical Coupling and Its Experimental Verification

Advances in Materials Science and Engineering, 2018
The effect of temperature and pressure, which play important roles in the mechanical properties of rocks during deep energy exploitation, has not been sufficiently studied in the previous rock creep models. In order to investigate thermal effect in creep

Experimental study on uniaxial creep characteristics of sandstone with pre-peak unloading damage

Scientific Reports, 2022
Deep resource extraction has been affected by the complex geological environment of "three highs and one disturbance" for a long time. The surrounding rocks experience strong unloading stress disturbance during the underground resource extraction.

Accelerated creep model for rock based on statistical damage principle

Yantu gongcheng xuebao, 2020
Aiming at the problems that the existing creep theoretical models cannot describe the accelerated creep characteristics of the viscoplastic phase of rock and how to determine the start conditions of its accelerated creep phase, the triaxial creep tests ...

Fractal derivative Nishihara rheology model and its application

Yantu gongcheng xuebao
The soft soil exhibits typical nonlinear rheological characteristics, while the traditional element models cannot accurately describe them. By replacing the conventional damper with a fractal damper and considering the damaging effects of soils, an ...

Nonlinear Creep Behavior and Viscoelastic-Plastic Constitutive Model of Rock-Concrete Composite Mass

Advances in Civil Engineering, 2020
The joint force deformation of rock-concrete composite structures is different from that of simple rock specimens or concrete specimens, such as the tunnel surrounding rock-lining concrete, dam foundations, and concrete.

Polypyridyl Coordination Motifs as Precursors for Ordered Carbonaceous Frameworks Toward High‐Density Ru Single‐Atom Catalysts

Angewandte Chemie International Edition, EarlyView.
Here, we introduce a molecular design principle that fundamentally expands the bottom‐up synthesis of single‐atom catalysts (SACs). Coordinatively flexible polypyridyl units enable bottom‐up formation of ordered carbonaceous frameworks containing atomically dispersed Ru (∼11 wt%) by simple carbonization.

Climate‐Related Disclosure and Bank Performance: Does Bank Type Matter?

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates whether climate‐related disclosure (CRD) affects the financial performance of conventional banks (CBs) and Islamic banks (IBs) differently. Using a unique hand‐collected dataset on CRD for 591 banks (422 CBs and 169 IBs) from 24 countries over a 4‐year period, we examine how the relationship between CRD and financial ...

Investigating the Electrochemical Double Layer with Quantum‐Chemical Simulations and Implicit Solvation Models

Chemistry – A European Journal, EarlyView.
ESM‐RISM is applied to model electrochemical interfaces and benchmarked against Poisson–Boltzmann and molecular dynamics results. Density profiles, differential capacitance, and adsorption energetics at the gold–electrolyte interface are analyzed, highlighting the capabilities of this implicit electrolyte framework.

Association between GLIM‐defined malnutrition and in‐hospital costs in adults with sepsis: A sub analysis of a prospective cohort study

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background International statements suggest using the Global Leadership Initiative on Malnutrition (GLIM) criteria in intensive care units (ICUs); however, the economic impact of GLIM‐defined malnutrition in sepsis remains unclear. This study investigated the association between GLIM‐defined malnutrition and in‐hospital costs in sepsis ...
