Researchers have successfully explained how iron-based dyes work on a molecular level in solar cells. The new findings will accelerate the development of inexpensive and environmentally friendly solar cells.
A growing field called nanotechnology is allowing researchers to manipulate molecules and structures much smaller than a single cell to enhance our ability to see, monitor and destroy cancer cells in the body.
Researchers have discovered that the chemical structure of melanin on a macromolecular scale exhibits, amongst other shapes, a four-membered ring - in other words, a chemical structure that may be conducive to creating certain kinds of batteries based on natural melanin pigments.
Granular materials are one of the least understood forms of matter due to the incredibly complex ways that those particles interact. But those complicated physics also offer tantalizing potential to create materials with unique properties - like the ability to absorb impact energy in customized ways.
What do you get if you combine nanotextured 'Cassie' surfaces with the Leidenfrost effect? Highly water-repellent surfaces that show potential for developing future self-cleaning windows, windshields, exterior paints and more.
There's a lot of stuff you'd expect to find in baby formula: proteins, carbs, vitamins, essential minerals. But parents probably wouldn't anticipate finding extremely small, needle-like particles. Yet this is exactly what a team of scientists recently discovered.
Researchers have directly detected the Peltier effect in graphene. They showed that the effect can be switched from heating to cooling by tuning the type and density of the charge carriers inside the material.
