The thermodynamic method for fractal analysis is applied to mercury intrusion data. The results for representative commercial carbon black samples and a series of resorcinol-formaldehyde (RF) freeze-dried gels for different values of the molar ratio of resorcinol (R) to catalyst (C) are discussed in relation with the type of behavior exhibited by the samples during mercury porosimetry measurements. The obtained surface fractal dimensions are compared with those derived previously from the small-angle X ray scattering (SAXS) and the nitrogen adsorption. Copyright 1999 Academic Press.

Alternating- and direct-current (ADC) bipolar electropolymerization (EP) offers an efficient and scalable approach for the lateral synthesis of conjugated macromolecules, enabling the simultaneous polymerization and deposition of large conducting polymer films with intriguing fractal-like ramified topographies onto arbitrary insulating substrates under remote control. In this study, we presented the remote synthesis of poly(3,4-ethylenedioxythiophene) (PEDOT):anion sensing films on a plastic substrate, aimed at their use in flexible nitrogen dioxide (NO) gas sensors. Notably, the PEDOT:ClO films exhibited excellent gas-sensing characteristics, with a sensitivity of 54.

Objectives: Previous studies reported various methods of measuring fracture toughness of dental ceramics. The objectives of this study were to compare different methods and to validate fractal analysis to estimate fracture toughness for a polycrystalline dental ceramic.
Methods: Bar-shaped specimens were prepared from 3 mol% yttria-stabilized tetragonal polycrystalline (3Y-TZP) ceramic.
The study of mechanical properties and fracture evolution of coal-rock masses under hard roof-soft floor conditions.

As the depth of coal mining in China continues to increase, the fracturing of coal rock masses has an increasingly complex impact on the surrounding rock roadways. The majority of the mine's roadways run through coal rock masses with hard roofs and soft bottoms, which typically exhibit complex dynamic behaviour. To further research the mechanical behaviour and fracture evolution of coal rock masses under hard-roof and soft-floor conditions, the study is based on the majority of working faces in a mine, which have hard roofs and soft floors.

Pancreatic Ductal Adenocarcinoma (PDAC) is a devastating disease with poor clinical outcomes, which is mainly because of delayed disease detection, resistance to chemotherapy, and lack of specific targeted therapies. The disease's development involves complex interactions among immunological, genetic, and environmental factors, yet its molecular mechanism remains elusive. A major challenge in understanding PDAC etiology lies in unraveling the genetic profiling that governs the PDAC network.
