Numerical Simulation of Non-Stationary Parameter Creep Large Deformation Mechanism of Deep Soft Rock Tunnel

open access: yesApplied Sciences, 2022
The accelerated creep plays an important role in the disasters of soft-rock tunnels under high stress. However, most of previous studies only involved attenuation creep and uniform creep.

Ultra‐Thick Carbon Microhoneycomb Cathode for High‐Capacity Lithium‐Oxygen Batteries

open access: yesCarbon Energy, EarlyView.
This work demonstrates ultra‐thick biochar‐derived carbon microhoneycomb cathodes for lithium‐oxygen batteries. The penetrated macrochannels serve as highly efficient pathways for Li+ and O2 and provide abundant accommodation space for the discharge product. The optimized cathode achieved a high areal capacity of 38.2 mAh cm–2, providing guidelines for

Dietary Patterns and Risk of Colorectal Cancer Subtypes Classified by Fusobacterium nucleatum in Tumor Tissue [PDF]

open access: yes, 2018
Importance—Fusobacterium nucleatum appears to play a role in colorectal carcinogenesis through suppression of host immune response to tumor. Evidence also suggests that diet influences intestinal F. nucleatum. However, the role of F.

Polarity on Demand: Nucleophilic, Electrophilic, and Ambiphilic Reactivity at a 9,10‐Dihydro‐9,10‐Disilaanthracene Platform

open access: yesChemistry – A European Journal, EarlyView.
A 9,10‐dihydro‐9,10‐disilaanthracene platform was efficiently synthesized and features intrinsically electrophilic Si sites. Upon stepwise reductive Si─H bond cleavage, these Si sites are converted into nucleophilic centers. This controlled polarity switching also enables ambiphilic reactivity within a homo‐heteroelement framework.

Spallative ablation of dielectrics by X-ray laser

open access: yes, 2009
Short laser pulse in wide range of wavelengths, from infrared to X-ray, disturbs electron-ion equilibrium and rises pressure in a heated layer. The case where pulse duration $\tau_L$ is shorter than acoustic relaxation time $t_s$ is considered in the ...

Mapping the Socialization Externalization Combination Internalization Model's Evolution: A Systematic Literature Review for Future Research

open access: yesKnowledge and Process Management, EarlyView.
ABSTRACT This systematic literature review examines the evolution and contemporary relevance of the SECI model in knowledge management. A hybrid methodology, combining bibliometric analysis with the TCCM (Theories, Contexts, Characteristics, Methods) framework, was used to provide a comprehensive overview of the research domain.
