PHOTOOXIDATION SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
Polimerlerin Foto-oksidasyonu
Foto oksidasyon, bir polimer yüzeyinin oksijen veya ozon varlığında parçalanmasıdır. Etki, UV veya yapay ışık gibi ışınım enerjisi ile kolaylaştırılır. Bu süreç, polimerlerin hava koşullarında en önemli faktördür. Foto oksidasyon, polimerin molekül ağırlığını azaltan kimyasal bir değişikliktir. Bu değişikliğin sonucu olarak malzeme çekme, darbe ve uzama gücünde bir azalma ile daha kırılgan hale gelir. Renk bozulması ve yüzey yumuşaklığı kaybı foto-oksidasyona eşlik eder. Yüksek sıcaklık ve lokalize stres konsantrasyonları foto-oksidasyonun etkisini önemli ölçüde arttıran faktörlerdir. UV ışınlarının polipropilen halat üzerine etkisi ...
İngilizce sözlükte photooxidation sözcüğünün tanımı
Sözlükte fotooksidasyon tanımı fotoexcitation nedeniyle bir elektron kaybıdır. Fotoksidasyonun diğer tanımı, ışığın neden olduğu oksijenle olan reaksiyonudur.

been demonstrated by their reponse to common free-radical catalysts and
inhibitors. Irradiation with near ultraviolet light promotes oxidation even of benzyl

As there is more than sufficient photooxidation taking place in the ocean to
oxidize all the terrestrial CDOM, photooxidation is probably the dominant removal
mechanism for this CDOM as well as a removal mechanism for some marine-
