Oznake: metamateriali;negativni lomni količnik;negativna relativna dielektričnost;negativna relativna permeabilnost;uporabnost;diplomske naloge;
Pri tem diplomskem delu bomo spoznali, še dokaj novo idejo uporabe materialov, kjer njihove lastnosti ne izhajajo iz kemijske sestave, ampak iz strukture. Osnovno načelo metamaterialov je, da takšnih materialov ne najdemo v naravi in da so umetno izdelani. Začetek diplomskega dela obsega začetke nas ...

The effects of microplastics (MP) are extensively studied, yet hazard data from long-term exposure studies are scarce. Moreover, for sustainable circular use in the future, knowledge on the biological impact of recycled plastics is essential. The aim of this study was to provide long-term toxicity d ...

The COVID-19 pandemic has increased the use of disposable plastics, including medical masks, which have become a necessity in our daily lives. As these are often improperly disposed of, they represent an important potential source of microplastics in the environment. We prepared microplastics from p ...
