Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory, in collaboration with Brookhaven National Laboratory and three universities, have conducted a study that combined supercomputer simulation and X-ray characterization of a unique peroskite material that gradually "forgets", like the human brain, and could one day be used for advanced bio-inspired computing.

The material in the study, called a quantum perovskite, offers researchers a simpler non-biological model of what "forgetfulness" might look like on an electronic level. The perovskite shows an adaptive response when protons are repeatedly inserted and removed that resembles the brain's desensitization to a recurring stimulus.

Researchers from Samsung and Sungkyunkwan University announced that it has developed a new perovskite-based technology for X-ray machines that can cut radiation exposure by 90%. Samsung said that the new X-ray system comes with better sensitivity and is capable of collecting data while exposing patients to less radiation.

The commercialization of the technology may pave the way for the creation of X-ray devices that can scan full bodies, as previous methods had limitations the size of detectors. "If we overcome the remaining technological hurdles," Samsung said, "it could lead to advances in X-ray medical imaging technology that cuts radiation exposure to one tenth that of existing machines".

The Riken research institute in Japan recently announced that it has found a new candidate material for perovskite solar cells, by using the "K" supercomputer to carry out a search based on high-efficiency material screening.

The supercomputer enables running simulations in which elements of a well-known compound are replaced with different elements to theoretically design a compound with new functions prior to an experiment. This technology can be used, for example, for finding suitable replacements for compounds that are toxic due to lead like methylammonium-lead-iodine and formamidine-lead-iodine.
