Transparent conducting oxides (TCO’s) have widespread uses as electrodes in solar cells and liquid crystal displays and as heat-reflecting window coatings. The commercial TCO of choice is ITO (tin-doped indium oxide). ITO has a typical conductivity of 1!5]103 S/cm and a transparency 85—90% in thin films (1). In addition to ITO, which has been reviewed (2), a number of promising TCO’s consisting...
The Sn(IV) atom in the title salt, [N(CH(3))(3)(C(6)H(5))](2)[SnBr(4)(C(6)H(4)Cl)(2)], exists in a distorted all-trans SnC(2)Br(4) octa-hedral geometry. The Sn(IV) atom lies on a center of inversion. Weak inter-molecular C-H⋯Br hydrogen bonding is observed between trimethyl-phenyl-ammonium cations and the Sn complex anion in the crystal structure.
The valence band (VB) electronic structure and VB alignments at heterointerfaces of strained epitaxial stannate ASnO3 (A=Ca, Sr, and Ba) thin films are characterized using in situ X-ray and ultraviolet photoelectron spectroscopies, with band gaps evaluated using spectroscopic ellipsometry. Scanning transmission electron microscopy with geometric phase analysis is used to resolve strain at atomi...
OBJECTIVE The aim of this study was to determine an orthorexia nervosa scale score for and evaluate orthorexic tendency among students of nutrition and dietetics according to various sociodemographic characteristics. METHODS This cross-sectional study was carried out in May and June of 2016 among 208 students in the nutrition and dietetics department at a university in Istanbul. After receivi...
Introdução: A ortorexia nervosa (ON), tem sido amplamente estudada como um comportamento alimentar patológico, com alta prevalência em estudantes universitários, apesar de não ser considerada transtorno alimentar. Objetivo: avaliar a por uma revisão literatura sobre o conceito e partir das pesquisas realizadas questionário Orto-15. Métodos: Os participantes responderam formulário caracterização...
