Three spiro-acridine-fluorene based hole transporting materials (HTMs), namely CW3, CW4 and CW5, are employed in the fabrication of organic-inorganic hybrid perovskite solar cells. The corresponding mesoscopic TiO2/CH3NH3PbI3/HTM devices are investigated and compared with that made with commercial spiro-OMeTAD. The best conversion efficiency of 16.56% is achieved for CW4 in the presence of tBp ...

Resumo— Este trabalho apresenta um modelamento genérico para IMU (Inertial Measurement Unity). Através de ajustes de parâmetros de desempenho de sensor tais como bias, ruı́do e resposta em frequência além de outros, o modelamento oferece capacidade para simular desempenho de sensor desejado. possibilitando testar requisitos de sensor e desempenho. O modelo é comparado com uma simualação de senso...

We suggest that all horizons of spacetime, no matter whether they are black hole, Rindler, or de Sitter horizons, have certain microscopic properties in common. We propose that these properties may be used as the starting points, or postulates, of a microscopic theory of gravity. ∗ e-mail: [email protected]

The surface spin wave branches in ferromagnetic films are studied using a microscopic theory which considers both magnetic dipole-dipole and Heisenberg exchange interactions. The dipole terms are expressed in a Hamiltonian formalism, and the dipole sums are calculated in a rapidly convergent form. The Damon-Eshbach surface modes are analyzed for different directions of the spin-wave propagation...

OBJECTIVE The aims of this study were to obtain cross-sectional data on capillaroscopy in an international multi-center cohort of Systemic Sclerosis (SSc) and to investigate the frequency of the capillaroscopic patterns and their disease-phenotype associations. METHODS Data collected between June 2004 and October 2011 in the EULAR Scleroderma Trials and Research (EUSTAR) registry were examine...

Autoantibodies against components of neutrophil cytoplasm develop during adult vasculitic diseases such as Wegener's granulomatosis and microscopic polyarteritis, and they are predominantly of the IgG class. Similar but distinct antibodies have been described in children with Kawasaki disease and both IgM and IgG class antibodies are represented. This adds another clinically distinct childhood ...

The microscopic theory of current carrying states in the ballistic superconducting microchannel is presented. The effects of the contact length L on the Josephson current are investigated. For the temperatures T close to the critical temperature Tc the problem is treated selfconsistently, with taking into account the distribution of the order parameter ∆ (r) inside the contact. The closed integ...
