Graphene carpets: So neurons communicate better

13.06. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

A study led by SISSA and published in Nature Nanotechnology reports for the first time the phenomenon of ion trapping by graphene carpets and its effect on the communication between neurons. The researchers have observed an increase in the activity of nerve cells grown on a single layer of graphene. Combining theoretical and experimental approaches, they have shown that the phenomenon is due to the ability of the material to 'trap' several ions present in the surrounding environment on its surface, modulating its composition. Graphene is the thinnest bi-dimensional material available today, characterised by incredible properties of conductivity, flexibility and transparency. Although there are great expectations for its applications in the biomedical field, only very few works have analysed its interactions with neuronal tissue.

Ocean carbon imaged on the atomic scale

05.06. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Dissolved Organic Carbon (DOC) in the ocean is one of the largest pools of reduced carbon on Earth. It's about 200 times larger than the living biosphere and comparable in size to the atmospheric CO2 reservoir.  Due to its complexity, less than 10 percent of dissolved organic carbon has been characterized.  It's important to understand what this carbon pool is, so we can predict how this pool of carbon will respond to increasing temperatures from climate change.

Photoexcited graphene puzzle solved

04.06. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Light detection and control lies at the heart of many modern device applications, such as smartphone cameras. Using graphene as a light-sensitive material for light detectors can offer significant improvements with respect to materials being used nowadays. For example, graphene can detect light of almost any color, and it gives an extremely fast electronic response within one millionth of a millionth of a second. Thus, in order to properly design graphene-based light detectors it is crucial to understand the processes that take place inside the graphene after it absorbs light.
