[EN] The production of carbon fibers based on Polyacrylonitrile (PAN) precursor fibers is a very
energy intensive process. In order to increase the energy efficiency, microwave plasma
processes and, alternatively, ...

[EN] In this research, we ameliorated the problems of carbon quantum dots synthesis and
luminescence (quantum yields) by the novel synthesis protocol using microwave chemistry.
Specifically, we synthesized high quantum ...

[EN] Uneven heating and hot spots, irregular matching conditions and deterioration of organoleptic qualities are typical drawbacks of magnetron-based food processing with microwave radiation. The proposed “Kopernicook” ...
[EN] For drying building structures, dielectric heating using RF energy (13.56 MHz) is an
efficient and fast alternative to conventional heating methods relying solely on heat transfer
from the surface to the interior ...
