Real‐Time Probing of Morphological Evolution and Recrystallization During Solvent Annealing in Blade‐Coated All‐Polymer Organic Solar Cells Using In Situ X‐Ray Scattering

Advanced Science, EarlyView.
In situ grazing‐incidence X‐ray scattering and in situ UV–vis spectroscopy are being used for the first time to reveal the morphological evolution of all‐polymer solar cell (APSCs) blends during solvent vapor annealing (SVA). SVA strongly influences the recrystallization and reordering behavior of APSCs blends, successfully establishing the ...

Microstructural Origin of Nonmonotonic Piezoresistivity in Polymer Nanocomposites

Advanced Science, EarlyView.
When polymer nanocomposites are subjected to tensile loading, the electrical resistance‐strain relationship may be nonmonotonic, hampering the use of these materials in real‐world applications. This challenge is addressed through the collaborative use of physical experimentation and computer simulations, establishing the inter‐nanotube junction ...

Multipole Moments of Fractal Distribution of Charges

, 2005
In this paper we consider the electric multipole moments of fractal distribution of charges. To describe fractal distribution, we use the fractional integrals. The fractional integrals are considered as approximations of integrals on fractals.

Quantum interference in nanofractals and its optical manifestation

, 2004
We consider quantum interferences of ballistic electrons propagating inside fractal structures with nanometric size of their arms. We use a scaling argument to calculate the density of states of free electrons confined in a simple model fractal.

Superelastic Fire‐Safe Aerogel with Hierarchical Structures via Dual Templates Aided by Microbubble Engineering

Advanced Science, EarlyView.
Here, a dual‐template strategy (ice and bubble template) is used to prepare fire‐safe aerogels with hierarchical structures. When the foam expansion ratio exceeds the jamming transition value in the foam system, the aerogels demonstrate superelasticity and extreme shape adaptability.

Fractal Dimension of Particle Showers Measured in a Highly Granular Calorimeter

, 2013
We explore the fractal nature of particle showers using Monte-Carlo simulation. We define the fractal dimension of showers measured in a high granularity calorimeter designed for a future lepton collider.

Interfacial Roughness‐Reinforced Magnetic Nanosheet Colloidal Gels for Stable Embolization and Magnetothermal Therapy of Hepatic Tumor

Advanced Science, EarlyView.
A rough‐interface reinforcement strategy is implemented to construct nanosheet‐mica‐based magnetic colloidal hydrogels with enhanced mechanical robustness and injectability. These hydrogels achieve stable vascular embolization and effective magnetothermal performance, offering synergistic therapeutic benefits in hepatic tumor treatment.

Switchable Bidirectional Sound Absorption Via Exceptional Point Modulation in Acoustic Metastructures with Interleaved Resonator Coupling

Advanced Science, EarlyView.
A switchable bidirectional acoustic metastructure is proposed, enabling broadband and frequency‐selective absorption via interleaved resonator coupling and exceptional point modulation. It outperforms traditional unidirectional designs, offering compact, efficient sound control from both directions and establishing a generalized framework for extending
