Abstract

Characterizing the properties of micro-/nanomaterials and micro-/nanospaces is crucial due to their widespread use in diverse applications, including analytical methods. While microspectroscopy offers a powerful characterization technique, limitations in acquisition speed and instrument accessibility persist. This study comprehensively explores the use of color coordinates to elucidate the chemical phenomena within confined micro-/nanospaces. Encoding spectral information directly as color coordinates within digital images enables rapid data acquisition. In addition, simple instrumentation that requires only a camera as a detector expands the versatility of solving tasks that occur in microspectroscopy. This work details the fundamental principles of color coordinates and presents illustrative research examples demonstrating their utility in characterizing chemical reactions and physicochemical properties within confined spaces. Herein, the evaluation of the chemical reactions occurring in the confined microspace is explained, including the steel corrosion occurring in the freeze concentration of the salt solutions (FCS) formed in the frozen salt solutions, proton-involved reactions in the FCS, liquid/liquid and solid/gel interface. This work aims to promote the adoption of image processing for colorimetric analysis as a complementary or alternative approach to conventional microspectroscopy.

显微图像中保存的颜色坐标在限定微/纳米空间中解释化学行为的应用。

表征微/纳米材料和微/纳米空间的性质是至关重要的，因为它们广泛应用于各种应用，包括分析方法。虽然微光谱学提供了一种强大的表征技术，但在采集速度和仪器可及性方面的限制仍然存在。本研究全面探讨了使用颜色坐标来阐明有限微/纳米空间内的化学现象。将光谱信息直接编码为数字图像中的颜色坐标，可以实现快速的数据采集。此外，简单的仪器只需要一个相机作为探测器，扩展了解决微光谱学中出现的任务的多功能性。这项工作详细介绍了颜色坐标的基本原理，并提出了说明性的研究实例，展示了它们在表征有限空间内的化学反应和物理化学性质方面的效用。本文解释了在密闭微空间中发生的化学反应的评价，包括在冷冻盐溶液中形成的冷冻浓度盐溶液（FCS）中发生的钢腐蚀，FCS中涉及质子的反应，液/液和固/凝胶界面。这项工作的目的是促进采用图像处理比色分析作为补充或替代方法，以传统的显微光谱学。
