Organo-copper(i) halide complexes with a Cu4I4 cubane core and cyclic amines as ligands have been synthesized and their crystal structures have been defined. Their solid state photophysical properties have been measured and correlated with the crystal structure and packing. A unique and remarkably high luminescence quantum yield (76%) has been measured for one of the complexes having the cubane...

aim. To monitor changes in the microbial component of gray forest soil under influence traditional and modern types fertilizers used agriculture. Methods. Microbiological, laboratory-analytical, statistical. Results. It has been established that use organo-mineral fertilization system allows to intensify development organic matter by 56.3%, mineralization nitrogen compounds 14.7%, increases oli...

N 2 and CO 2 gases adsorption by tetramethylammonium(TMA)-montmorillonites and hexadecylpyridinium(HDP)-montmorillonites was carried out using volumetric equipment at 25 °C and 0.1 MPa. The addition of organic compounds to montmorillonites was 1 and 4 times the cation exchange capacity (CEC) of the montmorillonites and the contact times between the TMA (or HDP) and the montmorillonites were 4 a...

The biosphere organic matter is stored in nature various forms. Most of it associated with classical terrestrial organo-mineral soils. carbon woody plant biomass counted separately from soil as the standing biomass. Nevertheless, humification a universal process already begins residues before they reach surface tropical mineral soil. Moreover, humid-forest ecosystems, most does not at all and a...

Lactols and cyclic hemiaminals were directly used in a one-pot organo/organo dual catalytic system induced [2+2+2] tandem reaction for the asymmetric construction of six-membered carbocycles. The enamine-based stereoselective Michael addition of lactols or cyclic hemiaminals to electron-deficient olefinic oxindole motifs provided chiral C4 components, which were further combined with triethylam...

Cropping systems with legumes play key roles in farming sub-Saharan Africa. However, how commonly legume associations perform low input-systems is not well-known. Here, we studied four species used three rotation upland rice, i.e., groundnut monocropping, sorghum–cowpea intercropping, and velvet bean–crotalaria two fertilization managements on the previous manure alone or complemented mineral f...

Abstract The study aimed to investigate the temporal changes of pH, sorption complex, and structure soil organic matter through forest profile under beech spruce forests located in Jizera mountains (Czech Republic) affected by natural anthropogenic acidification. Soil samples were collected four different years (2008, 2013, 2015, 2020) each horizon: fermented horizons (F), humified (H), organo-...

The spatial distribution of organic substrates and microscale soil heterogeneity significantly influence matter (OM) persistence as constraints on OM accessibility to microorganisms. However, it is unclear how changes in driven by factors such depth affect the relative importance substrate persistence. This work evaluated decomposition 13C 15N labeled water-extractable inputs over 50 days eithe...
