Influence of the concentration (0-1610 23 M) of Mo(IV) compounds on the electroless deposition of Co-Mo-P alloy from alkaline citrate bath was investigated. The changes of the plating potential, mass of the deposits and hydrogen evolution as well as composition and morphology of the deposits with the concentration of additives were determined. Similar behaviour was observed for all compounds. Increase in the MoO 2{ 4 concentration in the bath was accompanied by inhibition of Co-Mo-P deposition and only traces of deposits were obtained at 1610 23 M Mo(VI). Molybdenum content in the deposits was low and oxygen was detected in the layers produced at 5610 24 and 1610 23 M Mo(VI). Such changes corresponded to a gradual evolution of the morphology of the deposits from needle to fine grained structure, but Na 2 MoO 4 produced deposits of the best quality. Adsorption of MoO 2{ 4 ions at the metal/ electrolyte interface was proposed as responsible for phenomena observed in the Co-Mo-P system.
The way people perceive time is interesting in itself but also as a predictor of social, cognitive, and affective aspects of behavior. It is also a correlate of important psychological traits.
Migration plays an important role in shaping contemporary society in the European Union (EU), with constituent countries being affected differently. As a result of the most recent expansion of the EU in 2004, the United Kingdom (UK) has experienced an influx of economic migrants from former "Eastern Bloc" countries, including many young people from Poland. In this study, we explore the experiences of a group of nine young Polish adults living, studying and working in the UK. Three of the nine participants were co-researchers in this participatory action research, equipping them with the tools to undertake a narrative enquiry. The resultant narratives outline emergent themes and subthemes: including reasons for coming to and staying in the UK; first impressions of and changing opinions about life in the UK; the impact of visits to Poland; and plans for the future. The data add to the literature by providing a unique developmental perspective of the changing experiences of living in the UK; and give some insight into the life impacts of migration in contemporary Europe, amongst young people in their twenties.
The sensory properties of cosmetic emulsions are part of the basic properties of products such as face creams and body balms. They are extremely important parameters in the product evaluation by consumers. Cosmetics manufacturers are increasingly introducing ingredients in the form of solid particles (talc, bentonite, clay) into formulations to improve the sensory properties of products. Their addition simplifies the application of the emulsion on the skin, effects faster absorption and leaves a feeling of silky smoothness after application. During the work, we investigated solid particles of plant origin: powder from ground orange peel and oat grain. These ingredients were introduced into the formulation of the model body balms. The antioxidant and physicochemical properties of the obtained emulsions as well as the skin hydration after their application were evaluated. It has been shown that the introduction of solid plant particles increases the antioxidant properties of the emulsions and significantly improves emulsion stability and skin moisture after application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
