Tuning Colloidal Stability and Photothermal Conversion Efficiency of Graphite Nanofluids via Anionic‐Nonionic Surfactant Engineering

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Graphite nanofluids were stabilized using a mixed SDS/Tween 80 surfactant system. The optimized formulation exhibited enhanced colloidal stability, red‐shifted UV–Vis absorption, and improved photothermal conversion under solar irradiation. Achieving stable dispersion of graphite flakes (GFs) in aqueous media remains a critical challenge in developing ...

Liquid‐Mediated Kinetically Controlled Synthesis of Porous Carbon with Homogeneous Graphitic Networks for High‐Rate and High‐Loading Organic Supercapacitor

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Liquid‐mediated kinetic control reconstructs a “rigid–flexible” carbon precursor into homogeneously graphitized porous carbon. The resulting porous structure and homogeneous graphitic network accelerate ion/electron transport, enabling superior performance in high‐rate and high‐loading organic supercapacitors.

An algorithm for seizure detection in rodents

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Epilepsy animal research often relies on long‐term intracranial electroencephalographic (iEEG) recordings. Here, we describe an artificial neural network (ANN) algorithm for automatic detection of seizures. Methods The algorithm was trained on iEEG recordings of three mouse models of chronic epilepsy: (1) the pilocarpine model of ...

Research on Crack Propagation and Stress Propagation in Coal‐Rock Combinations Under Different In Situ Stresses Subjected to Blasting Loads

open access: yesEnergy Science &Engineering, EarlyView.
A stress wave propagation model for coal‐rock combinations under in situ stress was established. Taking a coal mine in Huainan, China as the engineering background, isotropic and anisotropic numerical models were constructed. Field engineering practices were carried out to verify the reliability of the conclusions.

On Complex Dimensions and Heat Content of Self-Similar Fractals

open access: yesFractal 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 ...

Damage Characteristics and Stress Distribution Law of Overburden Rock in Multiple Mining of Close Coal Seams

open access: yesEnergy Science &Engineering, EarlyView.
This study on close coal seams shows that multi‐seam mining increases the height of the fractured zone from approximately 26 m (single upper‐seam mining) to about 49 m. When the lower seam is mined after the extraction of the upper seam, the heights of both the caved zone and the fractured zone increase by approximately two times.

Mechanical stability in flexible perovskite solar cells: Interface engineering and device design

open access: yesFlexMat, EarlyView.
Statistics of the improvement methods for f‐PSCs. Abstract Flexible perovskite solar cells (f‐PSCs) demonstrate significant potential for application in next‐generation wearable electronic devices and photovoltaic building integration due to their high power conversion efficiency and excellent power‐to‐weight ratio. However, the inherent brittleness of

Donor‐acceptor fractal synergy: Decoding self‐similarity for stable organic photovoltaics

open access: yesFlexMat, EarlyView.
Morphological congruence between donor and acceptor refines the fractal structure of bulk heterojunction films and enhances their self‐similarity. This optimized multiscale morphology preserves charge‐transport pathways against external disturbances, suppresses structural degradation, and improves the operational stability of organic solar cells while ...
