AB  - Lowlands of Central Serbia are mostly covered by alluvial soils, while the natural vegetation types are various alluvial forests differentiated by the distance from the river bad (dynamics of soil water potential regimes) and gradients of  soil structure, nutrient availability and soil pH (Marjanovic et al 2020). These forests have been heavily exploited for timber throughout the human history, but what has remained still represent significant hotspots of above and belowground biodiversity. The rare specificity of these ecosystems is the high diversity of truffles, fungi producing belowground fruiting bodies, among which the most prised white Piedmont truffle holds a special attention (Bragato and Marjanovic, 2016). 
In order to describe these special habitats of Balkan Peninsula, we have conducted various experiments, mostly concentrated on soils that support the fructification of this ecologically and economically important species. In this contribution we will summarize results on soil structure, soil water content dynamics, nutrient availability, seasonality of soil processes as well as seasonality of root associated mycobiomes of selected alluvial forests. We focus on connecting the fructification of white truffle to different soil factors (Marjanovic et al 2015), as well as on defining the differentiation factors that have been shaping root associated mycobiomes (Marjanovic et al 2020). The contribution was set to uncover as many soil traits as possible to reveal the answer to the question of what are the ideal conditions of soil/vegetation /climate combination that is suitable for such specific fungal communities.

AB  - Efficient cathodes for the hydrogen evolution reaction (HER) in acidic
water electrolysis rely on the use of expensive platinum group metals (PGMs). However, to
achieve economically viable operation, both the content of PGMs must be reduced and
their intrinsically strong H adsorption mitigated. Herein, we show that the surface effects of
hydrogenated TiO2 nanotube (TNT) arrays can make osmium, a so far less-explored PGM,
a highly active HER electrocatalyst. These defect-rich TiO2 nanostructures provide an
interactive scaffold for the galvanic deposition of Os particles with modulated adsorption
properties. Through systematic investigations, we identify the synthesis conditions (OsCl3
concentration/temperature/reaction time) that yield a progressive improvement in Os
deposition rate and mass loading, thereby decreasing the HER overpotential. At the same
time, the Os particles deposited by this procedure remain mainly sub-nanometric and
entirely cover the inner tube walls. An optimally balanced Os@TNT composite prepared at
3 mM/55 °C/30 min exhibits a record low overpotential (η) of 61 mV at a current density
of 100 mA cm−2, a high mass activity of 20.8 A mgOs
−1 at 80 mV, and a stable performance in an acidic medium. Density functional
theory calculations indicate the existence of strong interactions between the hydrogenated TiO2 surface and small Os clusters, which
may weaken the Os−H* binding strength and thus boost the intrinsic HER activity of Os centers. The results presented in this study
offer new directions for the fabrication of cost-effective PGM-based catalysts and a better understanding of the synergistic electronic
interactions at the PGM|TiO2 interface.
