Imagine seeing the world in muted shades gray sky, gray grass. Some people with color blindness see everything this way, though most can t see specific colors. Tinted glasses can help, but they can t be used to correct blurry vision. And dyed contact lenses currently in development for the condition are potentially harmful and unstable. Now, in
ACS Nano, researchers report infusing contact lenses with gold nanoparticles to create a safer way to see colors.
Scientists at St Petersburg University have developed a new technology to prevent lithium-ion batteries from catching fire. What scientists propose is to use a chemical fuse to cover the main conductor cable of the battery. It is a special protective covering made from conducting polymer. In case of abnormal situation, it breaks circuits and prevents the battery from catching fire.

Most people are probably familiar with the unpleasant feeling of eating overripe or underripe fruit. Those who work in agriculture are tasked with ensuring a timely harvest so that ripeness is at an optimal point when the fruit is sold, both to minimize the amount of fruit that goes to waste and maximize the quality of the final product. To this end, a number of techniques to assess fruit ripeness have been developed, each with their respective advantages and disadvantages depending on the type of produce.

Researchers at Tokyo Institute of Technology working in collaboration with colleagues at the Kanagawa Institute of Industrial Science and Technology and Nara Medical University in Japan have succeeded in preparing a material called cerium molybdate (γ-Ce2Mo3O13 or CMO), which exhibits high antiviral activity against coronavirus.
The ongoing coronavirus pandemic has highlighted the urgency not only of vaccine development and rollout but also of developing innovative materials and technologies with antiviral properties that could play a vital role in helping to contain the spread of the virus.

Advances in wearable devices have enabled e-textiles, which fuse lightweight and comfortable textiles with smart electronics, and are garnering attention as the next-generation wearable technology. In particular, fiber electronic devices endowed with electrical properties, while retaining the specific characteristics of textiles, are key elements in manufacturing e-textiles.
Optoelectronic devices are generally constructed using layers of semiconductors, electrodes, and insulators; their performance is greatly affected by the size and structure of the electrodes. Fiber electronic components for e-textiles need to be fabricated on thin, pliable threads; sin
