How iron can be used to store and transport energy
Gaining sustainable energy from wind, solar and water is commonly known and applied. However, renewable sources depend on environmental conditions: in peak times of wind and sun, excess energy is produced that is needed in times of less wind and sunshine. But how to store and transport this ...
Energy in Iron and its Oxides
Transporting green-generated energy in form of iron: That is the vision of a project funded by the German Federal Ministry of Education and Research and coordinated by UDE. Hydrogen produced by solar energy, a chemical reaction and transport in metal form lead to a sustainable cycle to produce ...
A new, versatile method for temperature monitoring in materials
The right temperature matters – whether in technical processes, for the quality of food and medicines, or the lifetime of electronic components and batteries. For this purpose, temperature indicators record (un)desired temperature increases that can be read out later. Researchers in the group led ...
‘Smart rust is cheap to make and ecologically sound’
We can only guarantee that objects are manufactured in an environmentally friendly, socially sustainable way and recycled correctly if all raw materials and intermediate products are marked unambiguously using a tamper-proof method. The current optical (barcode) and electromagnetic (RFID chip) ...
Scientists observe vibrational dynamics of organic acid molecules on iron oxide surface
A Hamburg research team is paving the way for new methods of producing tailor-made materials: for the first time, the scientists from DESY NanoLab and the Hamburg University of Technology (TUHH) have deciphered the collective arrangement of organic acid molecules on an iron oxide surface at the ...
Scientists develop new material for tomorrow's technology
Smartphones with large glass housings and displays are impressive, but they are also very prone to get cracked and scratched. To prevent these kinds of damages, a material combining the hardness of diamond and the deformability of metals would be ideal – and is indeed considered the holy grail of ...
Catalyst based on a substance that comes from plant waste
Many production facilities (e.g. plastic manufacturers, pharma companies, and others) use nanocatalysts that contain palladium--an expensive component that is not sustainably produced. A chemist from RUDN University found a way to reduce palladium consumption and to make its manufacture more ...
Providing Safe, Clean Water
In many parts of the world, access to clean drinking water is far from certain. Filtration of large volumes of water, however, is slow and impractical. In the journal Angewandte Chemie, scientists have introduced a new water purification method based on magnetic nanoparticles coated with a ...
Producing nanomaterials from plant extracts
A team of scientists from Ural Federal University (Yekaterinburg), Bangladesh University of Engineering and Technology and other collaborator have published an article about a new method for the synthesis of magnetic nanoparticles. Today nanoparticles are used in various fields, from biomedicine ...
Inspired by the flashing colors of the neon tetra fish, researchers have developed a technique for changing the color of a material by manipulating the orientation of nanostructured columns in the material. "Neon tetras can control their brightly colored stripes by changing the angle of tiny ...
