Simple measurement of surface free energy using a web cam
Neste trabalho, descrevemos uma experiência simples e pedagógica para medir a energia livre de superf́ıcie (SFE) que é um tema dominante no ensino da F́ısica, a ńıvel de estudos de graduação e pós-graduação. A vantagem desta experiência baseia-se na simplicidade dos materiais utilizados, ou seja, produtos de baixo custo e não prejudiciais, como água, glicerol, etileno glicol e propanol, que ofere...
متن کاملMicromechanical measurement of active sites on silicon nitride using surface free energy variation.
We have investigated chemical reactions between adsorbed water and active sites on a silicon nitride surface as a function of temperature and relative humidity using microcantilevers. Effects that might produce a change in the response of the microcantilever, such as a mass adsorption, surface tension of the adsorbed water, and changes in thermal conductivity, were systematically investigated. ...
متن کاملNovel Poly (glycerol-adipate) Polymers Used for Nanoparticle Making: A Study of Surface Free Energy
Nanoparticles made of biodegradable polymers has become the best approach for nanoparticle making due to their compatibility with the human body. New glycerol adipate polymers with hydroxyl group substituted with different percent of acyl group, sited as figures within the abbreviated name in the text, and triptophan were synthesized and proposed to be used in the preparction of dexamethason ph...
