a photosensor based on lead free perovskite like methyl ammonium bismuth iodide
Sensors and Actuators A-physical, 2019Co-Authors: Kai Eckhardt, Julia Grothe, Nicolas Perez, Bertold Rasche, Alexander Zeugner, Thomas Doert, Kornelius Nielsch, Stefan KaskelAbstract:Abstract Methylammonium bismuth iodide (CH3NH3)3Bi2I9 (MBI) is a promising Hybrid Organic-Inorganic Material for photo-voltaic applications. A complete photodetector with a fast response time, in the order of 150 ms, was fabricated using MBI crystals grown via anti-solvent diffusion crystallization. Analyzing single crystals under varying illumination intensities clearly revealed an illumination dependant carrier density providing good photodetector performance. While band structure calculations predict a band gap of 1.4 eV, a more complex transport mechanism is revealed by Hall measurements, indicating the presence of states within the band gap close to the Fermi energy, possibly originating from crystallographic defects or internal redox processes.

crystallographic insights into ch3nh3 3 bi2i9 a new lead free Hybrid organic inorganic Material as a potential absorber for photovoltaics
Chemical Communications, 2016Co-Authors: Kai Eckhardt, Volodymyr Bon, Jurgen Getzschmann, Julia Grothe, Florian M Wisser, Stefan KaskelAbstract:The crystal structure of a new bismuth-based light-absorbing Material for the application in solar cells was determined by single crystal X-ray diffraction for the first time. (CH3NH3)3(Bi2I9) (MBI) is a promising alternative to recently rapidly progressing Hybrid organic–inorganic perovskites due to the higher tolerance against water and low toxicity. Single crystal X-ray diffraction provides detailed structural information as an essential prerequisite to gain a fundamental understanding of structure property relationships, while powder diffraction studies demonstrate a high degree of crystallinity in thin films.

pre osteoblastic cell response on three dimensional organic inorganic Hybrid Material scaffolds for bone tissue engineering
Journal of Biomedical Materials Research Part A, 2013Co-Authors: Konstantina Terzaki, Maria Kissamitaki, Amalia Skarmoutsou, C Fotakis, Costas A Charitidis, Maria Farsari, Maria VamvakakiAbstract:Engineering artificial scaffolds that enhance cell adhesion and growth in three dimensions is essential to successful bone tissue engineering. However, the fabrication of three-dimensional (3D) tissue scaffolds exhibiting complex micro- and nano-features still remains a challenge. Few Materials can be structured in three dimensions, and even those have not been characterized for their mechanical and biological properties. In this study, we investigate the suitability of three novel Materials of different chemical compositions in bone tissue regeneration: a Hybrid Material consisting of methacryloxypropyl trimethoxysilane and zirconium propoxide, a Hybrid organic–inorganic Material of the above containing 50 mole% 2-(dimethylamino)ethyl methacrylate (DMAEMA) and a pure organic Material based on polyDMAEMA. More specifically, we study the mechanical properties of the aforementioned Materials and evaluate the biological response of pre-osteoblastic cells on them. We also highlight the use of a 3D scaffolding technology, Direct femtosecond Laser Writing (DLW), to fabricate complex structures. Our results show that, while all three investigated Materials could potentially be used as bioMaterials in tissue engineering, the 50% DMAEMA composite exhibits the best mechanical properties for structure fabrication with DLW and strong biological response. © 2013 Wiley Periodicals, Inc.

maya blue as a nanostructured polyfunctional Hybrid organic inorganic Material the need to change paradigms
New Journal of Chemistry, 2009Co-Authors: Antonio Doménech, Maria Teresa Domenechcarbo, Maria Pascual, Enrique LimaAbstract:Maya Blue, an ancient nanostructured organic–inorganic Hybrid Material resulting from the attachment of indigo, a natural dye, to a phyllosilicate clay, palygorskite, has received considerable attention of late. Despite intensive research, several aspects remain unsolved, in particular the nature of the indigo–palygorskite association. Recent results suggest that the Maya Blue pigment is a complex system in which different topological isomers of various indigoid molecules attached to the palygorskite matrix coexist.
