What are solid-state batteries?
In solid-state batteries, both electrodes and the electrolyte consist of solid material. Although some solid-state batteries are already in use […]
What are liquid electrolyte batteries?
Liquid electrolyte batteries have been used for many years and are currently the most commonly used batteries, e.g. lithium ion […]
What types of liquid electrolytes are there?
Liquid electrolytes are mostly water-based salt solutions consisting of organic and inorganic acids. However, simple saline solutions can also be […]
What types of rechargeable batteries (secondary batteries) are there and where are they used?
There are a variety of rechargeable batteries or secondary batteries, which can be roughly divided into liquid electrolyte batteries (also […]
What is the difference between perovskite and conventional solar cells?
Conventional solar cells are often made of silicon dioxide, which is used in amorphous or crystalline form. It takes a […]
Graffiti protection and easy-to-clean surfaces – how does that work and is it safe?
Special coatings are used to generate self-cleaning surfaces or anti-graffiti-protection. The coatings are virtually invisible and protect the base material […]
Is the UV-protection in nanomaterial-containing sunscreens only effective if the nanomaterials enter the skin and how are they excreted later?
No, to effectively act as inorganic UV-blocker (also called mineral UV-blocker) in sunscreen, the materials either in nanoform or lager […]
Can nanomaterials used in sunscreen cross the skin barrier and enter the body?
Typically nanomaterials used in sunscreens like titanium dioxide or zinc oxide (inorganic uv-blockers) as well as the organic nanoscale UV-blockers […]
Nanosilver in the mattress – what is the purpose and is it safe?
In many cases, silver threads are woven into the mattress’ cover and the fabric can be additionally impregnated with a […]
How can you produce safe nano-textiles?
The Swiss project NanoSafe Textiles has carefully assessed current and future applications of synthetic nanoparticles in textiles and evaluated their potential […]
