BODIPY atropisomer interconversion, face discrimination, and superstructure appending
2016
International audience; A strategy was developed to append sterically hindered apical pickets on both faces of the BODIPY platform to prevent stacking and aggregation. Ortho-substitution of both the meso-phenyl ring and the boron-bound catechol affords the right directionality to append pickets, achieve face discrimination, featuring two inter-convertible atropisomers, and is reminiscent of the picket-fence strategy in porphyrins.

Influence of Nitrogen Doping on Device Operation for TiO₂-Based Solid-State Dye-Sensitized Solar Cells: Photo-Physics from Materials to Devices.
2015
Solid-state dye-sensitized solar cells (ssDSSC) constitute a major approach to photovoltaic energy conversion with efficiencies over 8% reported thanks to the rational design of efficient porous metal oxide electrodes, organic chromophores, and hole transporters. Among the various strategies used to push the performance ahead, doping of the nanocrystalline titanium dioxide (TiO2) electrode is regularly proposed to extend the photo-activity of the materials into the visible range. However, although various beneficial effects for device performance have been observed in the literature, they remain strongly dependent on the method used for the production of the metal oxide, and the influence o…
Postępy w fotowoltanice w Polsce i na świecie = Progress in photovoltaics in Poland and the world
2015
W artykule przedstawiono postęp w zakresie uzyskiwanych sprawności przez ogniwa i moduły fotowoltaiczne (PV) wykonane z różnych materiałów i za pomocą różnych technologii. Zawarto w nim szczegółowe zestawienia tabelaryczne sprawności oraz ich parametrów technicznych. Zwrócono uwagę na nowe obiecujące technologie, które jeszcze nie mają rekordowych sprawności, ale z uwagi na proces ich wytwarzania rokują nadzieje na uzyskanie bardzo dużych sprawności albo tanich wielkopowierzchniowych modułów do komercyjnego zastosowania. Ponadto, omówiono ekonomiczne skutki wdrożenia nowo zawartych zapisów w uchwalonej w lutym 2015 r. Ustawie o Odnawialnych Źródłach Energii (OZE) dla rozwoju rozproszonych i…
Optical quality of hyperopic and myopic phakic intraocular lenses
2013
Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…

El útero es uno de los principales órganos internos del sistema reproductor femenino. Está compuesto de tres capas tisulares: perimetrio, miometrio y endometrio. Esta última capa recubre la cavidad intrauterina y es responsable directa de la implantación embrionaria (para la cual necesita un grosor endometrial mínimo). Entre las patologías que afectan al endometrio pueden distinguirse, entre otras, la atrofia endometrial (insuficiente grosor endometrial) y el síndrome de Asherman (presencia de adhesiones intrauterinas y tejido fibrótico), las cuales conforman el hilo conductor de esta tesis, compuesta de 4 artículos científicos. En ambos casos, el tejido endometrial se encuentra degenerado,…
