Geoactive soil fungi were investigated for phosphatase-mediated uranium precipitation during growth on an organic phosphorus source. Aspergillus niger and Paecilomyces javanicus were grown on modified Czapek-Dox medium amended with glycerol 2-phosphate (G2P) as sole P source and uranium nitrate. Both organisms showed reduced growth on uranium-containing media but were able to extensively precip...

Materials based on biodegradable polyesters such as poly(butylene terephthalate) (PBT) 20 or poly(butylene terephthalate-co-poly(alkylene glycol) terephthalate) (PBTAT) have potential 21 application as pro-regenerative scaffolds for bone tissue engineering. Herein is reported the 22 preparation of films composed of PBT or PBTAT and an engineered spider silk protein, 23 (eADF4(C16)), that displa...

to fit the nucleus of the cubic polymorph (Fig. 2b). Conversely, the nucleus of a triclinic crystal would be a poor fit to pores with right-angled corners because the crystal would need to incorporate either strain or defects. As a consequence, right-angled pores should selectively favour nucleation of the cubic polymorph. Another application of nanopatterned surfaces may be found in surface-in...

This work demonstrates the fabrication of partially mineralized scaffolds fabricated in 3D shapes using paper by folding, and by supporting deposition of calcium phosphate by osteoblasts cultured in these scaffolds. This process generates centimeter-scale free-standing structures composed of paper supporting regions of calcium phosphate deposited by osteoblasts. This work is the first demonstra...

Element incorporation in shell calcite precipitated by foraminifera reflects the chemical and physical properties of seawater lived can therefore be used to reconstruct paleo environmental conditions. One most prominent proxies for past temperature is Mg/Ca foraminiferal calcite. Still, addition temperature, also biomineralization processes impact values. As plays a major role not necessarily c...

Problematic microfossils dominate the palaeontological record between the Great Oxidation Event 2.4 billion years ago (Ga) and the last Palaeoproterozoic iron formations, deposited 500-600 million years later. These fossils are often associated with iron-rich sedimentary rocks, but their affinities, metabolism, and, hence, their contributions to Earth surface oxidation and Fe deposition remain ...
