A study on the fractal characteristics of displacement time-series during the evolution of landslides

open access: yesGeomatics, Natural Hazards & Risk, 2016
Landslides are one of the major natural disasters that are frequently occurring in southwestern China. The main objective of this study is to investigate the relationship between failure of landslide and fractal dimension using displacement time-series ...

Influence of Raw‐Material Processing on Gold and Silver Nanoparticles Stability Using Ultrasound‐Extracted Pink‐Pepper Compounds

open access: yesChemistry &Biodiversity, EarlyView.
Schinus terebinthifolius extract and metal nanoparticle synthesis. ABSTRACT The ultrasound‐assisted green synthesis of gold (AuNPs) and silver nanoparticles (AgNPs) from Schinus terebinthifolius extracts delivered stable colloids whose physicochemical properties depend on raw‐material preprocessing.

Self‐Assembly of Heterochiral and Homochiral Peptides Conjugated to PNA Dimers and Their Integration in Peptide‐Based Hydrogels

open access: yesChemistry – A European Journal, EarlyView.
Homochiral PNA‐peptide conjugates mixed to homochiral peptides yield hydrogels supporting cell growth. Abstract Hybrid biomolecules composed of short peptides and nucleic acid analogues can self‐assemble and are good candidates to produce new materials thanks to their biocompatibility and versatility.

Fractal dimensions of fractal transformations and quantization dimensions for bi-Lipschitz mappings

open access: yesJournal of Fractal Geometry, Mathematics of Fractals and Related Topics
In this paper, we study the fractal dimension of the graph of a fractal transformation and also determine the quantization dimension of a probability measure supported on the graph of the fractal transformation. Moreover, we estimate the quantization dimension of the invariant measure corresponding to a weighted iterated function system consisting of ...

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)

Controls on carbonate island formation and evolution: South Joulter Cay, Great Bahama Bank

open access: yesThe Depositional Record, EarlyView.
The evolution of South Joulter Cay occurs in three stages: linear ridges shaped by waves and longshore currents, arcuate ridges influenced by tidal currents and channels, and cuspate ridges formed by variable wind and wave directions. These processes are driven by climatic and oceanographic factors.
