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

open access: yesChemSusChem, 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)

Manipulating drying‐induced carbon nanotube assemblies through substrate surface engineering

open access: yesDroplet, EarlyView.
During the observation of CNT droplet drying on modified substrates with varying surface properties, high‐friction surfaces induced long‐range orientation of CNTs through fixed contact lines and material flow during evaporation. This provides a programmable substrate strategy for assembling ordered nanostructures via controlled droplet drying ...

Fractal Patterns in Reasoning [PDF]

open access: yes, 2011
This paper is the third and final one in a sequence of three. All three papers emphasize that a proposition can be justified by an infinite regress, on condition that epistemic justification is interpreted probabilistically.

Financial Applications of Human Perception of Fractal Time Series

open access: yes, 2015
The purpose of this thesis is to explore the interaction between people’s financial behaviour and the market’s fractal characteristics. In particular, I have been interested in the Hurst exponent, a measure of a series’ fractal dimension and ...
