A polymeric photosensitizer, poly(NIPAM-co-RB), consisting of N-isopropylacrylamide and rose bengal units, demonstrates a temperature-controlled changeable oxygenation selectivity by singlet oxygen in water.

In the present work, a new polymeric adsorbent; Poly(NIPAM-co-AN)/clay composite was prepared via in-situ polymerization. The copolymerization of N-isopropylacrylamide, acrylonitrile and calculated clay (about 5% w/w) were carried out at 65°C in presence 10 mL 1,4-dioxane using AIBN as an initiator. Characterization P(NIPAM-co-AN)/clay determined by FT-IR techniques. NIPAM-AN/clay has been used...

Abstract Three different dosimetry systems were prepared based on diphenyl thiocarbazone (DTH) dye: polymer films made with, poly(vinyl alcohol), DTH liquid dosimeter and gel dosimeter. All the received several gamma doses. The three analyzing by UV–Vis spectrophotometery before after irradiation. effective dose range in linear part of these is between 1–10 kGy, 0.3–2 50–200 Gy. dosimeters reli...
