This is a qualitative study that aims to describe the opinion of nursing students on the use of an educational hypermedia on Peripheral Venipuncture. We interviewed 16 nursing students of a private university on second semester of 2014. The interviews allowed the identification of units of meaning and categorization by content analysis and led to four categories: influence of hypermedia on learning, educational technology as support to teaching classroom, contribution of hypermedia for professional practice and access difficulties. Hypermedia showed positive results as most scholars reported that the material helped in learning and generated autonomy and interactivity in the moment of studying. However some reported difficulties in access hypermedia related mainly to the server used. So hypermedia proved to be a valuable tool to use, since it favored the learning and aroused the interest and curiosity of students.

Obtaining Thin Film of SnO2/Cu2O and Characterization by X-Ray Diffraction

引用

Journal of Chemistry and Chemical Engineering 2014年第12期8卷 1104-1108页

作者： Francisco Marcone Lima Maria Katiane Diogenes marques Paulo Herbert Franca Junior Igor frota de Vasconcelos Ana Fabiola Leite Almeida Francisco Nivaldo Aguiar Freire Technology Center Federal University of Ceara Fortaleza 60455-900 Brazil

Thin films of tin and copper oxide forming heterojunction are being studied for applications in photovoltaic systems. The procedure for obtaining such a film was based on the technique of spray pyrolysis with working temperature of 600 °C. The XRD (X-ray diffraction) showed the formation of tin oxides (SnO2) and copper (Cu2O) and its structural parameters are a, b and c, 4.7534 ?, 4.7534 ?, 3.1998 ? (tetragonal form) and 4.2580 ?, 4.2580 ?, 4.2580 ? (cubic form), respectively. Highscore Plus program was used for phase identification and DBWSTool2.4 program used for refinement. The grain size was estimated by Williamson-Hall.
