Blastability Classification of Fractured Rock Mass Based on Weighted Clustering Analysis
Chemical Engineering Transactions, 2017 This paper classifies the blastability of fractured rock mass based on the solid coefficient, rock impedance, unit explosive consumption and mean fracture spacing. Specifically, an evaluation model was established according to the principle of clustering

The effect of drainage on the capillary retention of CO2 in a layered permeable rock [PDF]
, 2008 Buoyant plumes of CO2 spreading through water-saturated permeable rock, bounded by layers of lower permeability, tend to spread laterally. As they advance, they may gradually leak through fractures or discontinuities in the lower permeability boundary ...

Non-Linear FEM Analysis for the Layered Rock-Mass Tunnel Based on the Twin Shear Strength Criterion
, 2010 According to the geotechnical conditions, A FEM model has been established to analyse the mechanical characteristics of the highway tunnel in the layered rock mass. In this model the layered rock mass and the soften joint are simulated by the transversal

An Index for Estimating the Stability of the Layered Rock Masses under Excavation Disturbance
Advances in Materials Science and Engineering, 2018 The mechanical behaviours of layered rock mass exhibit significant differences in the directions parallel and vertical to the bedding planes. The deformation and failure of a layered rock mass has remarkable weak-plane dependence, which brings a major ...

Sn-Driven Grain Boundary Elimination for Single-Crystalline Ni-Rich Cathodes with Superior High-Voltage Stability in Lithium-Ion Batteries. [PDF]
Adv Sci (Weinh)A low‐temperature synthesis method of single‐crystalline NCA was successfully achieved by Sn doping, employing the same synthetic conditions as its polycrystalline counterparts. This synthesis was conducted at a temperature that was 150 °C lower than that required for synthesizing single‐crystalline NCA without Sn doping.

Rock mass ratings and properties
, 2019 Engineers have excavated rocks for mining and tunnel purposes for hundreds of years. Unfortunately, there have been several occasions where a section or the whole tunnel collapsed in weak or heavily weathered rocks.

FEBS Letters, EarlyView.Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

FEBS Letters, EarlyView.Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...
