Advanced Science, EarlyView.We report, for the first time, an external electric field (EEF) strategy to achieve co‐aggregation of conjugated polymer blends (i.e., poly(3‐butylthiophene) and poly[3,3'''‐dialkyl‐quaterthiophene]s) in the solution and thus their cocrystals in thin films, demonstrating cocrystal‐improved charge mobilities due to the synergy of two components ...

Fractal image compression [PDF]
Fractals are geometric or data structures which do not simplify under magnification. Fractal Image Compression is a technique which associates a fractal to an image. On the one hand, the fractal can be described in terms of a few succinct rules, while on

Reconfigurable Acoustofluidic Microvortices for Selective Microcargo Delivery
Advanced Science, EarlyView.This work introduces a frequency‐encoded, reconfigurable acoustofluidic system that overcomes the low throughput and poor selectivity of conventional micro‐delivery methods. By exploiting discrete microbubble resonances to program adaptive microvortex modes, the platform enables real‐time switching and selective guidance of microscale payloads through ...

Fractality in selfsimilar minimal mass structures
, 2017 In this paper we study the diffusely observed occurrence of Fractality and Self-organized Criticality in mechanical systems. We analytically show, based on a prototypical compressed tensegrity structure, that these phenomena can be viewed as the result ...

Advanced Intelligent Discovery, EarlyView.CrossMatAgent is a multi‐agent framework that combines large language models and diffusion‐based generative AI to automate metamaterial design. By coordinating task‐specific agents—such as describer, architect, and builder—it transforms user‐provided image prompts into high‐fidelity, printable lattice patterns.

Survey on Fractal image compression
Journal of Research in Science, Engineering and Technology, 2020 The need for multimedia applications has increased over the years. Due to this issue, image and video compression becoming an essential problem in reducing time and data storage. Fractal Image Compression (FIC) is a compression technique which results in loss, and we can have large amounts of compression.

Fractal image compression: A resolution independent representation for imagery [PDF]
A deterministic fractal is an image which has low information content and no inherent scale. Because of their low information content, deterministic fractals can be described with small data sets.
