This paper describes a new class of anti-stiction coatings for silicon MEMS that is based on the free radical reaction of a primary alkene (e.g., 1-octadecene, C16H33CH=CH2) with hydrogen terminated silicon [1,2]. The new monolayer coating has several key advantages over the previously reported octadecyltrichlorosilane (OTS) and 1H,1H,2H,2Hperfluorodecyltrichlorosilane (FDTS) based self-assembl...

Coated multiparticulate systems are increasingly popular on the market. Their manufacture in a fluid bed often requires polymer binders. Polymers have been widely studied as inhibitors of crystallization [1]. Migration of drugs into the coating layer has also been described [2] but the influence of the coating polymers on the crystallization of the drug is yet to be studied in more depth. In ou...

In this paper, two-step sequential spin-dip and spin-spin coating, as well as one-step spin coating, methods are used to fabricate methylammonium lead mixed-halide perovskites to study the effect of process parameters, including the choice of the solvent, annealing temperature, spin velocity, and dipping time on the characteristics of the perovskite film. Our results show that using a mixture o...

Anxiety is feeling of danger in a person who is threatening with something. Nowadays, anxiety is increased in different populations and, thus it is became an important problem in many countries. Melissa officinalis (Melissa) and Valeriana officinalis (Valerian) are two medicinal plants. These two plants are traditionally used as sedative herbal drugs and new studies on their pharmacological act...

In this study, the polydopamine (PDA) film was coated on polished 316Lss and then thermally treated at 150 °C (labeled as PDA-Th150), and the stability of coatings was also investigated. Straining test indicated that PDA-Th150 coating performed better in affording sufficient adherence to 316 L SS substrate. Moreover, both PDA and PDA-Th150 coating suffered slight swelling during immersion in de...
