  • Plasma Synthesis of Carbon Films
    Argemiro S. Argemiro S. / Armstrong Godoy Junior / Douglas M. G. Leite
    The aim of this work was to use plasma processes to deposit thin carbon films on certain substrates (glass, silicon and FTO-coated glass) and then corrode them in SF6 plasma combined with H2, O2 and Ar in order to increase the roughness and consequently the contact area of these films with the electrolyte of a dye-sensitized solar cell (DSSC). The films produced were characteri...

  • Synthèse par plasma de films de carbone
    Argemiro S. Argemiro S. / Armstrong Godoy Junior / Douglas M. G. Leite
    Le but de ce travail était d’utiliser des procédés plasma pour déposer des films minces de carbone sur certains substrats (verre, silicium et verre revêtu de FTO) puis de les corroder dans un plasma SF6 combiné à H2, O2 et Ar afin d’augmenter la rugosité et par conséquent la surface de contact de ces films avec l’électrolyte d’une cellule solaire à colorant (DSSC). Les films pr...

  • Роль наночастиц серебра в очистке загрязненной воды
    Русул Саеед Радхи
    Некоторые из экстрактов имели хороший потенциал для терапевтического применения против некоторых патогенов. Оказалось, что экстракты с высокой антимикробной активностью против грамотрицательных бактерий не обязательно обладают высокой активностью против других грамотрицательных бактерий по сравнению с грамположительными бактериями. Экстракт серебряных наночастиц Lilium candidum...

    All the matter that we see around us is made up of atoms and can be characterized by its properties. The matter can be categorized into three states: solid, liquid, and gas. For example, ice is solid, the vapour is gas, and water is liquid at the Standard Temperature and Pressure (STP). Some macroscopic observables, such as temperature, pressure, etc., are control parameters. T...

    Our current understanding of nature is in terms of matter that is acted on by forces. There are four fundamental forces, of which three are described by so-called gauge theories, a type of quantum field theory. The fourth force, gravity, is best described by general relativity, and our traditional ways of thinking about gauge theories and gravity look completely different from ...
