In this research, Novel UV curable conductive nanocomposites containing urethane acrylate and PANi-Co3O4 nanocomposite have been prepared. At first, PANi- Co3O4 nanocomposites have been synthesized and then PUA-PANi-Co3O4 nanocomposites films were prepared by ultraviolet radiation. UV-Vis and FT-IR studies confirm that there was strong chemical interaction between PANi and Co3O4 nanoparticles, ...

اخیرا با کاربرد ترمیمهای همرنگ غیرمستقیم، تحقیقات جهت یافتن ماده مناسب جهت چسباندن این ترمیمها وسعت زیادی یافته است. سیمانهای رزینی به لحاظ استحکام، زیبایی، و ضخامت لایه ای مطلوب، کاربرد مناسبی در این زمینه دارند و انواع آنها با سیستمهای مختلف پلیمریزاسیون (شیمیایی، نوری، dual) بدین منظور توصیه شده اند؛ لیکن سیمانهای dual cure به دلیل ادعای کارخانه ها مبنی بر این که پس از قطع نور، پلیمریزاسیون ...

Replica molding of ultra-high-Q toroidal microresonators can produce polymer microresonators with material-limited quality factors (Q). This was demonstrated previously using polymers which cure thermally. In this work, high Q polymer microresonators were fabricated using the replica molding technique from previously uncharacterized polymers which require either a thermal or UV cure. The qualit...

It has been argued that a self-interacting massive vector field is pathological due to dynamical formation of singular effective metric the field, which onset gradient or ghost instability. We discuss this singularity not necessarily fundamental problem but breakdown theory (EFT) description field. By using model ultraviolet (UV) completion we demonstrate Proca star, self-gravitating condensate...

Ultraviolet light emitting diodes (UV-LEDs) have attracted great interest in recent years. They can be used to polymerize coatings, such as those used for prefinished wood flooring. In this project, two lamps were compared for their suitability to be used on a wood flooring finishing line: a UV-microwave and a UV-LED lamp. Low heat emission was found for the UV-LED lamp compared to the UV-micro...

Direct ink writing (DIW) offers a flexible and readily available processing route for achieving ceramic components with complex shapes geometries. The successful printing of green bodies using DIW typically requires the formulation particle-loaded inks having narrow window rheological properties that enable both flow through nozzle support weight additional layers. Herein, we present method emp...

A simple process which utilizes a 2D stamp based on UV-NIL is proposed. The main idea is to control the cured region on the micrometer scale by using a developable resist. For the conventional UV-NIL process, a collimated UV light is transmitted through the transparent stamp to cure the overall resist as shown in Fig. S1a. However, if the size of the UV light is reduced, the cured region of the...

Mask projection microstereolithography (MPμSL) uses a dynamic mask and focusing optics to digitally pattern UV light and selectively cure entire layers of photopolymer resin. These systems have been shown to be capable of creating parts with features smaller than 10μm. In this paper, the authors analyze existing MPμSL systems using functional decomposition. Within the context of a morphological...
