Where did those electrons go? X-ray measurements solve decades-old mystery

Nanowerk.com - 7 ноября, 2017 - 16:51
There's been an unsolved mystery associated with mixed valence compounds: When the valence state of an element in these compounds changes with increased temperature, the number of electrons associated with that element decreases, as well. But just where do those electrons go? Using a combination of state-of-the-art tools, researchers have come up with the answer.

CNT/MOF nanocomposites enhance the performance of humidity sensors

Nanowerk.com - 7 ноября, 2017 - 16:41
Metal-organic frameworks (MOFs) are well-ordered, lattice-like crystals. The nodes of the lattices are metals, which are connected by organic molecules. Their size-controllable nanopores, special structure and large surface area make MOFs very attractive materials for next-generation, highly sensitive gas sensors. In new work, researchers demonstrate a process that can be used for developing low-cost and highly sensitive gas sensors. By increasing the sensitivity, the amount of gas sensitive material and device size can be reduced which in turn would reduce the overall cost of the device and energy consumption.
