A resorcinol resin/water dispersion and a rubber latex are added to 1% 2,2,6,6,-tetramethylpyperidine-1-oxyl (TEMPO)-oxidized cellulose nanofibers (TEMPO-CNFs) dispersed in water, followed by oven drying at 40 °C for 20 h prepare dried TEMPO-CNF/resorcinol resin/latex (DTRL) mixture with weight ratio of 1/0.5/3. DTRL is then nitrile-butadiene (NBR) or carboxy group-containing NBR (X-NBR) sheet,...
Introduction: Di (2-ethylhexyl) phthalate is one of the most abundant phthalate esters and it is widely used as softeners in plastic products. Malformation, carcinogenicity, the poisoning of the reproductive system, and also the disruption of the human endocrine system are the harmful effects of these substances. Materials and Methods: In this research, the removal of di (2-ethylhexyl) phthal...
هدف: شناسائی عملکرد پلیمر کلوسلجی با افزودن نانوالیاف سلولزِ BCN[1] و NFC[2] در دمای نرمشوندگی (Tg) با هدف ایجاد مادۀ پلیمری اصلاحشده برای مرمت آثار کاغذی. روش٫ رویکرد پژوهش: دادهها با استفاده از گرماسنج روبشی تفاضلی (DSC)[3] به روش استاندارد ASTM[4] گردآوری و با استناد به تجربیات آزمایشگاهی مرتبط تحلیل و تفسیر شدهاست.<br ...
We experimentally investigate the fluorescence photon emission characteristics for single q-dots by using optical nanofibers. We demonstrate that single q-dots can be deposited along an optical nanofiber systematically and reproducibly with a precision of 5 μm. For single q-dots on an optical nanofiber, we measure the fluorescence photon numbers coupled into the nanofiber and the normalized pho...
In this study, Poly (L-lactic acid)/Captopril composite nanofiber membranes were electrospun for drug delivery. Different mass fractions of Poly (L-lactic acid), different ratios of Captopril and the influences of PEG4000 added in the spinning solution are discussed. The morphology, chemical components, the surface areas and pore sizes, wettability of the composite nanofiber membranes were inve...
