Assessment of the PETase conformational changes induced bypoly(ethylene terephthalate) binding
(WileyWiley-Liss, 2021-06-02)
Recently, a bacterium strain of Ideonella sakaiensis was identified with the uncommon ability to degrade the poly(ethylene terephthalate) (PET). The PETase from I. sakaiensis strain 201-F6 (IsPETase) catalyzes the hydrolysis ...
Mechanistic insight into the formation of colloidal WS2 nanoflakes in hot alkylamine media

Energy Spotlight. Stabilization of Perovskite Solar Cells
(American Chemical Society, 2021-11-12)
Long-term operational stability remains a major challenge in the commercialization of perovskite solar cells (PSCs). While the major thrust of recent research effort has been on understanding the degradation mechanism, ...
Unveiling the stereoelectronic properties of a triphenylene-based tris N-heterocyclic carbene
(Royal Society of Chemistry, 2013-06-14)
Two rhodium complexes with a triphenylene-based tris-NHC have been fully characterized. DFT and electrochemical studies suggest that the electronic communication between the metals is very weak, and that the electron ...

Improved Stability of Inverted and Flexible Perovskite Solar Cells with Carbon Electrode
(American Chemical Society, 2020-06-02)
We demonstrate highly efficient, stable, and flexible perovskite solar cells of large areas, utilizing a carbon back-contact electrode in a p–i–n cell configuration. We enabled good electronic contact at the interface with ...
Gel–Polymer Electrolytes Based on Poly(Ionic Liquid)/Ionic Liquid Networks
(American Chemical Society, 2021-01-08)
The use of electrically charged, polymerized ionic liquids (polyILs) offers opportunities for the development of gel–polymer electrolytes (GPEs), but the rational design of such systems is in its infancy. In this work, we ...
Enhanced Open-Circuit Voltage of Wide-Bandgap Perovskite Photovoltaics by Using Alloyed (FA1–xCsx)Pb(I1–xBrx)3 Quantum Dots
(American Chemical Society, 2019-07-16)
We report a detailed study on APbX3 (A=Formamidinium (FA+), Cs+; X=I-, Br-) perovskite quantum dots (PQDs) with combined A- and X-site alloying that exhibit, both, a wide bandgap and high open circuit voltage (Voc) for the ...

(WileyWiley-VCH Verlag, 2021-01-19)
Sustainable electrocatalysis of the oxygen evolution reaction (OER) constitutes a major challenge for the realization of green fuels. Oxides based on Ni and Fe in alkaline media have been proposed to avoid using critical ...
Stabilization of Black Perovskite Phase in FAPbI3 and CsPbI3
(American Chemical Society, 2020-05-28)
Although halide perovskites allow a great versatility, the application on single-absorber solar cells restricts significantly the number of available materials. In this context, CsPbI3 and FAPbI3 (FA, formamidinium) present ...
