Advanced Functional Materials, EarlyView.Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

The evolution of mine waters quality at the locality of Smolník [PDF]
Acta Montanistica Slovaca, 2006 At the present time, acid mine drainage (AMD) is considered to be one of the worst environmental problems associated with the mining activity. AMD originates as a result of natural oxidation of sulphide minerals, mainly pyrite when exposed to the ...
