The ashes generated in the processes of coal combustion in the power industry can be converted into zeolites, so-called molecular sieves with a high CO2 capture efficiency, say scientists who have been investigating this possibility for over three years in an international research project.
Chemists from the Nicolaus Copernicus University in Toruń are working on membranes that will transport water better and retain salts and impurities. The starting point was the study of a desert beetle that can both collect and repel water. Ultimately, the solution can be used to obtain drinking water.
We live in modern times, that is full of electronics. Smartphones, laptops, tablets, and many other devices need electrical energy to operate. Portable devices made our lives easier, so novel solutions in clean energy and its storage are desirable. Lithium-ion (Li-ion) batteries are the most common solutions that dominate the global market and are a huge problem due to their insufficient recovery. Because of their limited power, short cycle life, and non-environment-friendly nature, scientists recently focused on novel solutions like supercapacitors that offer much more than batteries. Why? Let's take a look closer at these devices.
