Jul 11, 2022 (Nanowerk Spotlight) Hydrogels are fascinating natural or synthetic polymer materials that exhibit very versatile chemistries and physical or biological properties. They are 3D networks of either physically or chemically cross-linked polymers that resemble organic tissues and that can hold large amounts of water within their interlocked molecular...
Nanoparticles can save historic buildings
Jul 11, 2022 (Nanowerk News) Many historical buildings were built of limestone, such as Vienna's St. Stephen's Cathedral. Limestone is easy to work with, but does not withstand weathering well. It consists mainly of calcite minerals that are relatively weakly bound to each other, which is why parts of the...

What do molecules look like?
Jul 11, 2022 (Nanowerk News) A molecule is a group of atoms bonded together. Molecules make up nearly everything around you – your skin, your chair, even your food. They vary in size, but are extremely small. You can’t see an individual molecule with your eyes or even a microscope....

Future smart homes could be powered with electronics built on stones
Jul 11, 2022 (Nanowerk News) What if you could power the smart thermostats, speakers and lights in your home with a kitchen countertop? Stones, such as marble and granite, are natural, eco-friendly materials that many people building or renovating houses already use. Now, in a step toward integrating energy storage...
Black Hole Hunters – A citizen science search for black hole self-lensing
Jul 11, 2022 (Nanowerk News) A research team from the Open University and the University of Southampton is asking for the public’s help to find some of the most mysterious, elusive objects in the Universe – black holes. By examining data from the SuperWASP survey, the UK's leading extra-solar planet...

Physicists discover a ‘family’ of robust, superconducting graphene structures
Jul 09, 2022 (Nanowerk News) When it comes to graphene, it appears that superconductivity runs in the family. Graphene is a single-atom-thin material that can be exfoliated from the same graphite that is found in pencil lead. The ultrathin material is made entirely from carbon atoms that are arranged in...
