We present mapping results in several rotational transitions of HC3N, C6H, both cyclic and linear C3H2 and C3H, towards the cyanopolyyne peak of the filamentary dense cloud TMC-1 using the IRAM 30m and MPIfR 100m telescopes. The spatial distribution of the cumulene carbon chain propadien...

One of the most important creation mechanisms of carbonaceous species, assuming bottom-up carbon growth occurs, is probably the transition from 1D (linear carbon chains) to 2D and 3D structures. Hence, our results may shed light on the more general unexplained creation of large carbon-based ...
Consequently, carbon atoms can link together in chains of almost any length and rings of various sizes, allowing for an enormous range in molecular size and shape. Moreover, the ability to form four bonds means there is potential for branching at each carbon in the chain. And each carbon at...
Carbon-based low-dimensional materials exist as chains and rings at the nanoscale that have great potential for application in nanodevices. However, some of these nanoscale structures are reactive on substrates and lose their properties. We investigate the mechanical and thermal properties of the low-...
Therefore, it can be assumed that the partial oxidation of aromatic rings and aliphatic carbon chains of polystyrene corresponds to the induction period of the reaction. The partial oxidation (C–H bond activation) seemed easier than the final depolymerization (C–C bond breakage) because almost no...
The life-cycle perspective, on the other hand, is considered in this study in the way that we based carbon impact calculations on input data which included supply chains, as far as possible (seeAppendix). This refers to the impact calculations of our own universities (UCB Birkenfeld and NTU...
complex chains of biochemical reactions are aggregated in ‘macroscopic’ fluxes of C or N. Similarly, soil water changes dynamically in space and time. In practice, however, only soil moisture estimates at the soil core scale or larger are common. Hence, both biochemical fluxes and soil moistur...
Carbon forms a large number of compounds because of its unique ability to form stable covalent bonds with other carbon atoms and also with hydrogen, oxygen, nitrogen, and sulphur atoms, resulting in the formation of a variety of compounds containing chains and rings of carbon atoms. ...
