On Complex Dimensions and Heat Content of Self-Similar Fractals

Fractal and Fractional
Complex fractal dimensions, defined as poles of appropriate fractal zeta functions, describe the geometric oscillations in fractal sets. In this work, we show that the same possible complex dimensions in the geometric setting also govern the asymptotics ...

Resource‐Efficient Electrodes with Metallized Woven‐Glass‐Grid Current Collectors for Lithium‐Ion Batteries

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The use of metallized glass‐based woven‐grids instead of metal foils as current collectors for LIBs leads to a significant reduction in metal usage by over 90 % and weight savings of more than 80 %, resulting in an 11 % increase in specific energy at the cell level. Abstract A novel class of resource‐efficient, woven‐glass‐grid current collectors (CCs)

Experimental study on dynamic behavior analysis of coal and its acoustic emission response characteristics under impact failure

Deep Underground Science and Engineering, EarlyView.
Based on acoustic emission response characteristics, it can be more accurate to identify the damage evolution process of coal under the combined dynamic and static loads, reveal the moment corresponding to coal damage, and identify the characteristics of coal failure. The research results are conducive to the further use of acoustic emission monitoring

Slit tube responses and rock fracture characteristics in slit charge blasting under high in situ stress

Deep Underground Science and Engineering, EarlyView.
In this article, the finite element method‐smoothed particle hydrodynamics adaptive coupling algorithm is applied to numerically simulate and analyze the dynamic response of the slit tube and the crack propagation under high in situ stress. The dynamic response of the slit tube mainly exhibits radial response in the vertical direction of the slit and ...

Fractals in $$S_b$$ S b -metric spaces

Complex & Intelligent Systems
This study aims to discover attractors for fractals by using generalized F-contractive iterated function system, which falls within a distinct category of mappings defined on $$S_b$$ S b -metric spaces.
