TL;DR: The discovery of CaCO3·6H2O crystals in natural sea ice provides the necessary evidence for the evaluation of previous assumptions and lays the foundation for further studies to help elucidate the role of ikaite in the carbon cycle of seasonally sea ice-covered regions.

TL;DR: It is demonstrated that using a solution-processed, fully bridged dinuclear Cu(I)-complex can yield very high efficiencies, and an optimized device gives a maximum external quantum efficiency.

TL;DR: This study provides first direct spectroscopic evidence for Tl(I) uptake by illite and indicates the need for further studies on the sorption of Tl to clay minerals and Mn-oxides and its impact on Tl solubility in soils.

TL;DR: The concentration, distribution, and speciation of selenium in different parts of wheat and Indian mustard, grown in a seleniferous area in Punjab, were investigated using synchrotron based (XAS) and classical acid digestion and extraction methods.

TL;DR: In this article, a detailed mineralogical, geochemical, and microbiological investigation of two tailing impoundments near the town of Pezinok, Slovakia is presented. But the primary objective of this study was the mineralogy that formed in the impoundment after the deposition of the tailings (so-called tertiary minerals), which are present as grains and as rims on primary ore minerals.
