The intensive development of new technologies, especially in the field related to the construction of new portable devices used as sensors for the detection of many chemical compounds has brought many surprising solutions. One of them is an electronic tongue that can answer various questions about unknown samples: presence and amount of some specific compound, contamination, spoilage, or providing seemingly unmeasurable information such as taste. Such devices, however, would not have succeeded without the development of efficient, fast and inexpensive sensors, such as electrochemical sensors. Recent paper published by the researchers from the Institute of Physical Chemistry, Polish Academy of Sciences led by dr. Emilia Witkowska Nery demonstrates the low-cost, ion-selective syringe electrodes to be used to quantify potassium level in a wide range of food products, and pharmaceutical supplements. Let’s take a look closer on this research.

A team of international researchers led by the Plasma Science and Fusion Technology Laboratory of the University of Seville, have demonstrated the key role that energetic particles play in the stability of a tokamak plasma edge. The findings have been published in Nature Physics and could be key for the design of compact fusion power plants.
