Abstract 3D bioprinting has developed tremendously in the last couple of years and enables fabrication simple, as well complex, tissue models. The international space agencies have recognized unique opportunities these technologies for manufacturing cell models basic research space, particular investigating effects microgravity cosmic radiation on different types human tissues. In addition, is capable producing clinically applicable grafts, its implementation therefore can support autonomous...
Bioprinting is considered a key technology for future space missions and currently being established on the International Space Station (ISS). With aim to perform bioink production as critical resource-consuming preparatory step already Earth transport cartridge "ready use" ISS, storability of bioinks investigated. Hydrogel blends based alginate methylcellulose are laden with either green microalgae species Chlorella vulgaris or different human cell lines including immortilized mesenchymal...
Abstract A series of eight new and three known cobalt polypyridyl‐based hydrogen‐evolving catalysts (HECs) with distinct electronic structural differences are benchmarked in photocatalytic runs water. Methylene‐bridged bis‐bipyridyl is the preferred scaffold, both terms stability rate. For a complex tetradentate methanol‐bridged bispyridyl–bipyridyl [Co II Br(tpy)]Br, detailed mechanistic picture obtained by combining electrochemistry, spectroscopy, photocatalysis. In acidic branch,...
Abstract A range of different N‐ and S‐containing heterocyclic bromides can be efficiently coupled with gaseous ammonia in the presence copper(II) acetylacetonate [Cu(acac) 2 ] as catalyst absence additional ligands. Unstable aminothiophenes aminobenzothiophenes further reacted situ to afford functionalized derivatives.
A new, molecular system for the light-driven production of hydrogen in aqueous solution was developed by combining a water-soluble tin porphyrin ([Sn(IV)Cl2TPPC], A) acting as photosensitizer with cobalt-based proton-reduction catalyst ([Co(III)Cl(dmgH)2(py)], C). Under visible light illumination and triethanolamine (TEOA) electron source, evolves H2 hours is clearly catalytic both dye catalyst. detailed analysis relevant redox potentials combination time-resolved spectroscopy resulted...
Cu diimine complexes present a noble metal free alternative to classical Ru, Re, Ir and Pt based photosensitizers in solution photochemistry, photoelectrochemical or dye-sensitized solar cells. Optimization of these dyes requires understanding factors governing the key photochemical properties: excited state lifetime emission quantum yield. The involvement exciplex formation deactivation photoexcited is question. We investigate excited-state structure [Cu(dmp)2]+ [Cu(dsbtmp)2]+ (dmp =...
Preventing hypoxic zones in 3D bioprinted mammalian cell-laden constructs using an internal oxygen supply could enable a more successful cultivation both vitro and vivo. In this study, the suitability of green microalgae as photosynthetic generators within was evaluated by defining investigating important parameters for co-culture. First, we assessed impact light-necessary photosynthesis-on two non-light adapted cell types defined red-light illumination temperature 37°C essential factors The...
