Femtosecond‐Laser‐Induced Physical Unclonable Random Maze Structure for Storage‐Free Encryption

open access: yesAdvanced Science, EarlyView.
Femtosecond‐laser‐induced gold random maze structures serve as multimodal physical unclonable functions for storage‐free encryption. Their stochastic optical, electrical, and Raman responses are generated by plasmon‐assisted Marangoni formation and converted into AES‐compatible keys without permanent secret‐key storage, offering a portable route toward

Strain‐Adaptive Dielectric Metamaterials via Bioinspired “Ligament‐Bone” Architecture for Ultrahigh‐Energy Capacitive Storage

open access: yesAdvanced Science, EarlyView.
A bioinspired strain‐adaptive ligament‐bone architecture achieves record‐high energy density of 26.1 J cm−3 and 90% efficiency at 600 MV m−1, coupled with a Young's modulus of 2.13 GPa. ABSTRACT Polymer dielectrics for capacitive energy storage face fundamental trade‐offs between breakdown strength, energy density, efficiency, and mechanical robustness.

The Hausdorff dimension and exact Hausdorff measure of random recursive sets with overlapping

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
We weaken the open set condition and define a finite intersection property in the construction of the random recursive sets. We prove that this larger class of random sets are fractals in the sense of Taylor, and give conditions when these sets have ...

Fractals and Nonlinearity of Ocean Waves

open access: yesJurnal Teknik Sipil, 2003
From observations using secondary field data and dimension calculations, ocean waves exhibit fractals. Fractals are also hypothesized to have a direct relation with the degree of the waves nonlinearity.

Review of Fractal and Fractal Derivatives in relation to the Physics of Fractals

open access: yes, 2013
Fractional and fractal derivatives are both generalizations of the usual derivatives that consider derivatives of non-integer orders. Interest in these generalizations has been triggered by a resurgence of clamor to develop a mathematical tool to describe “roughness” in the spirit of Mandelbrot’s (1967) Fractal Geometry. Fractional derivatives take the

Harnessing Li‐Ion Binding Energy for Solvation‐Guided Electrolyte Additive Design and Robust Solid Electrolyte Interphase Reinforcement

open access: yesAdvanced Science, EarlyView.
A solvation‐guided design strategy for electrolyte additives is established, identifying Li‐ion binding energy as a crucial determinant for effective interface reinforcement. ABSTRACT The rational design of electrolyte systems is essential for stabilizing the electrode−electrolyte interface to enhance the electrochemical performance of lithium‐ion ...
