Prediction and identification of point defect fingerprints in the X-ray photoelectron spectra of TiN$_x$

Autor: Ondračka, Pavel, Kümmerl, Pauline, Hans, Marcus, Mráz, Stanislav, Primetzhofer, Daniel, Holec, David, Vašina, Petr, Schneider, Jochen M.

We investigate the effect of selected N and Ti point defects in $B$1 TiN on N 1s and Ti 2p$_{3/2}$ binding energies (BE) by experiments and ab initio calculations. X-ray photoelectron spectroscopy (XPS) measurements of Ti-deficient TiN films reveal a

Supercapacitor Degradation Assesment by Power Cycling and Calendar Life Tests

Autor: Sedlakova Vlasta, Sikula Josef, Majzner Jiri, Sedlak Petr, Kuparowitz Tomas, Buergler Brandon, Vasina Petr

Publikováno v: Metrology and Measurement Systems, Vol 23, Iss 3, Pp 345-358 (2016)

Degradation of Supercapacitors (SC) is quantified by accelerated ageing tests. Energy cycling tests and calendar life tests are used since they address the real operating modes. The periodic characterization is used to analyse evolution of the SC par

Bond formation at polycarbonate | X interfaces (X = Al$_2$O$_3$, TiO$_2$, TiAlO$_2$) studied by theory and experiments

Autor: Patterer, Lena, Ondračka, Pavel, Bogdanovski, Dimitri, Mráz, Stanislav, Pöllmann, Peter J., Aghda, Soheil Karimi, Vašina, Petr, Schneider, Jochen M.

Interfacial bond formation during sputter deposition of metal oxide thin films onto polycarbonate (PC) is investigated by ab initio molecular dynamics simulations and X-ray photoelectron spectroscopy (XPS) analysis of PC | X interfaces (X = Al$_2$O$_

Towards Supercapacitors in Space Applications

Autor: Buergler Brandon, Faure Bertrand, Latif David, Diblik Lukas, Vasina Petr, Gineste Valéry, Simcak Marek

Publikováno v: E3S Web of Conferences, Vol 16, p 17003 (2017)

Supercapacitors offer a wide range of applications for space flight. The aim of this activity was to pursue life tests on commercial off the shelf (COTS) supercapacitors from different manufacturers, to evaluate their performance after long term vacu
