Blue and White Capsule Pill: Insights from Recent Research
Thermochromic Capsules in Textile Applications
Temperature-Induced Color Change in Capsules
Recent advancements in textile technology have led to the development of temperature-induced color-changing cotton fabrics. This innovation utilizes epoxy-modified thermochromic capsules, which change color from blue to white at a transition temperature of 53°C. The capsules are created through the hydrolysis-polycondensation of siloxane groups from 3-glycidoxypropyltrimethoxysilane (GPTMS) with the hydroxy groups of the capsules. The successful grafting of GPTMS onto the thermochromic capsules is confirmed by FTIR and XPS analyses.
Durability and Application
The thermochromic capsules exhibit excellent thermal stability, withstanding temperatures over 300°C. When these capsules are bonded to cotton fabric, they maintain their reversible color-changing properties, shifting from blue to white and back. The covalent bonding between the fabric and the capsules ensures high washing and rubbing fastness, making the modified fabric durable and suitable for practical applications.
Defect Detection in Pharmaceutical Capsules
Image Processing for Quality Control
In the pharmaceutical industry, ensuring the quality and consistency of pills is crucial. Advanced image processing techniques have been developed to detect defects in pharmaceutical pills, including capsules. These methods classify pills into tablets and capsules, with further classification based on shape and color. Specifically, blue and white capsules, among other color combinations, are considered in these quality control processes .
Types of Defects and Detection Methods
The image processing methods focus on identifying various defects such as variations in count, cracks, breaks, and inconsistencies in size and shape. For capsules, the detection system checks for the absence of capsules, size and shape variations, and the presence of capsules with incorrect colors. These automated systems enhance the accuracy and efficiency of defect detection, allowing non-defective pills to be reused and defective ones to be discarded, thereby maintaining the integrity of pharmaceutical products .
Conclusion
The integration of thermochromic capsules in textiles and the use of image processing for defect detection in pharmaceuticals represent significant advancements in their respective fields. The reversible color-changing properties of thermochromic capsules offer innovative applications in smart textiles, while image processing techniques ensure the quality and safety of pharmaceutical products. These technologies highlight the ongoing efforts to enhance functionality and reliability in various industries.
