The body of knowledge about the human brain is growing exponentially, but questions big and small remain unanswered. Researchers have been using electrode arrays to map electrical activity in different brain regions to understand brain function. Until now, however, these arrays have only been able to detect activity over a certain frequency threshold. A new…
Optical CO2 Sensor Useful for In Situ Practical Applications
Carbon dioxide (CO2) is a known pollutant that affects the performance of humans in workplaces, schools, and other indoor areas. Thus, the development of devices for sensing and monitoring CO2 levels is crucial for many fields such as food packaging and for human safety indoors. The Catalan Institute of Nanoscience and Nanotechnology (ICN2) groups —…
Nanoporous Graphene Incorporated into Smart Filters and Sensors
As part of a national research collaboration, Spanish researchers including the ICN2 have made uniformly nanoporous graphene a practicable reality. A major milestone in graphene research, this brings us one step closer to unlocking this wonder material’s full potential not only in electronics, but also in filtration and sensing applications. Presented at a press conference…
