Light and chemical oscillations: Review and perspectives
Journal of Photochemistry and Photobiology C: Photochemistry Reviews ( IF 12.8 ) Pub Date : 2019-11-10 , DOI: 10.1016/j.jphotochemrev.2019.100321

When UV–vis radiation interacts with matter, it can play as either a pump, or a developer, or a signal. In this paper, we show that when UV–vis radiation interacts with very-far-from-equilibrium systems, it can exert its threefold role. It can originate oscillations when it works as a pump. It can track the hydrodynamics of fluids by inducing fluorescence or colour formation of specific probes when it works as a developer. Finally, it can affect spontaneous chemical oscillations, chemical waves, Turing patterns, and promote synchronization phenomena when it works as a signal. A cross-disciplinary analysis of many experiments shows that the interplay between UV–vis radiation and very-far-from-equilibrium systems has promising technological applications. Such interaction can be exploited to control the morphology of materials, implement chemical systems for computing, and promote soft robotics. Since dissipative chemical systems exhibit life-like functionalities, this work can be inspirational for those researchers engaged in the study of the origin of life where spontaneous phenomena of self-organization induced by light are relevant.

光和化学振荡:回顾与展望

当紫外线可见辐射与物质相互作用时,它可以充当泵,显影剂或信号。在本文中,我们表明,当紫外线可见光与非常远离平衡的系统相互作用时,它可以发挥三重作用。当它作为泵工作时,可能会引起振荡。当它用作显影剂时,它可以通过诱导特定探针的荧光或颜色形成来跟踪流体的流体动力学。最后,它可以影响自发的化学振荡,化学波,图灵模式,并在用作信号时促进同步现象。对许多实验的跨学科分析表明,紫外线可见辐射与极不平衡的系统之间的相互作用具有广阔的技术应用前景。可以利用这种相互作用来控制材料的形态,实施用于计算的化学系统,并推广软机器人。由于耗散的化学系统表现出类似于生命的功能,因此这项工作对于那些研究生命起源的研究人员来说是鼓舞人心的,在这些研究中,与光诱导的自组织自发现象有关。
