Fracture Toughness and Acoustic Emission of Granite Under Pre-static and Cyclic Loading

工程科学与技术, 2018
The drilling and blasting method is the major excavation method for large underground caverns. Except for the load from in-situ stresses (static), the cavern rock mass will also bear the dynamic load frequently from blasting during excavation.

Experimental study on mechanical properties of red-bed mudstone under the action of water–rock hydro-mechanical coupling

Materials & Design
Red-bed mudstone, a key engineering material commonly encountered in infrastructure construction in rain-prone regions, exhibits critical instability under water exposure and excavation. Yet research linking its hydro-mechanical (HM) coupling behavior to

The Influence of Ethical Ideologies on Corporate Social Performance in Small and Medium‐Sized Enterprises in the United Kingdom

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Research addressing the microfoundations of corporate social performance (CSP) in small and medium‐sized enterprises (SMEs) remains sparse. This paper aims to investigate how SME managers' ethical ideology affects CSP and examines the mediating role of their CSR orientation (CSRO): economic, legal, ethical, and philanthropic.

Firm‐Level Corporate Social Responsibility and Employees' Affective Outcomes: A Multilevel Approach

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study advances research on corporate social responsibility (CSR) and employees' work attitudes by distinguishing between employee‐level CSR perceptions and firm‐level CSR practices. Prior research has mainly focused on how employees' perceptions of CSR relate to their affective outcomes; this study extends that perspective by jointly ...

Smart Functional Hydrogels: Emerging Platforms for Thermal and Electrochemical Energy Harvesting and Conversion Systems

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydrogel exhibits versatile functions, including efficient thermogalvanic conversion under a temperature difference, and acting as a cooling layer/forming a thermally conductive nanoactive composite for thermovoltaic conversion. Additionally, its self‐healing and self‐powered flexibility play a key role in energy storage systems. The growing demand

Asymmetric Synthesis of Tertiary α‐Aryl Stereocentres in Tetrahydro‐4H‐pyran‐4‐ones Using Pd‐Catalyzed Decarboxylative Asymmetric Protonation

European Journal of Organic Chemistry, EarlyView.
The Pd‐catalyzed decarboxylative asymmetric protonation (DAP) has been developed for sterically hindered tetrahydro‐4H‐pyran‐4‐one derived α‐aryl‐β‐keto esters. A substrate scope of nine examples of DAP showed that substrates containing a di‐ortho methoxy substitution pattern on the aryl ring gave rise to the highest enantioselectivities of up to 85 ...
