Can Depopulation Stop Deforestation? The Impact of Demographic Movement on Forest Cover Changes in the Settlements of the South Banat District (Serbia)

Frontiers in Environmental Science, 2022
The key problem of rural settlements in the South Banat district lasted into the 21st century through the spread of depopulated areas. Considering that settlements give a cultural landscape its basic features, that they are the main bearers of functional

GeSn on Insulators (GeSnOI) Toward Mid-infrared Integrated Photonics

Frontiers in Physics, 2019
In recent years, Ge and Ge1−xSnx materials and devices have achieved rapid progress in integrated photonics. However, conventional heteroepitaxy of active photonic devices compromises the area on Si for CMOS electronics, limiting the scale of integration.

Synthesis, Structure and Physical Properties of the Sodium‐Rich Phosphidogermanate Na8GeP4

Zeitschrift für anorganische und allgemeine Chemie, Volume 649, Issue 20, October 16, 2023., 2023
Abstract Sodium ion conductor materials hold promise to be an affordable substitute for ever growing lithium demand. To achieve high ionic conductivity in all‐solid state ion conductor materials, fundamental understanding of the atomic structure of the materials as well as the structure‐property relationship are basic prerequisites.

Spatial distribution of the CO2 stream in archaeological dark earth area under cocoa and coffee cultivation in the municipality of Apuí, AM, Brazil

Revista Ambiente & Água, 2016
The Archaeological Dark Earth (ADE) are soils that can hold up to six times more organic carbon than surrounding soils without anthropic horizons, thus assuming higher CO2 emissions from these soils.

Single‐Source Precursors for the Chemical Vapor Deposition of Iron Germanides

European Journal of Inorganic Chemistry, Volume 26, Issue 29, October 12, 2023., 2023
The reaction of GeCl2 ⋅ 1,4‐dioxane with Fe2(CO)9 gives [Cl2GeFe(CO)4]2, Cl2Ge[Fe2(CO)8]Ge[Fe2(CO)8] or Ge[Fe2(CO)8]2, depending on the educt ratio. [Cl2GeFe(CO)4]2, Ge[Fe2(CO)8]2 and Me₂iPr₂NHC ⋅ GeCl2 ⋅ Fe(CO)4 were characterized in their thermal decomposition behavior and applied as single source precursors in chemical vapor deposition, resulting in

Untersuchung von Ladungstransferprozessen in einer kovalent verknüpften [Ge9]‐Cluster‐Imin Dyade

Angewandte Chemie, Volume 135, Issue 29, July 17, 2023., 2023
Chemochrome Cluster. Silylierte [Ge9]‐Cluster bilden ein neuartiges Chromophorsystem. Die Protonierung einer kovalent an den Cluster gebundenen Imineinheit führt zu einem intensiven Farbwechsel von rot nach grün. Transiente Absorptionsspektroskopie und DFT‐Rechnungen an der protonierten Form zeigen eine ultraschnelle Dynamik bei Lichtanregung, die zu ...
