Iron catalysis at the origin of life [PDF]

, 2017
Iron–sulphur proteins are ancient and drive fundamental processes in cells, notably electron transfer and CO2 fixation. Iron–sulphur minerals with equivalent structures could have played a key role in the origin of life. However, the ‘iron–sulphur world’

Genome size evolution in the Archaea [PDF]

, 2018
What determines variation in genome size, gene content and genetic diversity at the broadest scales across the tree of life? Much of the existing work contrasts eukaryotes with prokaryotes, the latter represented mainly by Bacteria.

Optimization of Climate Neutrality for a Low-Energy Residential Building Complex in Poland

Energies
Since 2021, the design and construction of nearly zero-energy buildings (nZEBs) have been mandatory for European Union Member States. Subsequent requirements for the building sector, characterized by high energy demand and significant environmental ...

Mutational and structural studies of (βα)₈-barrel fold methylene-tetrahydropterin reductases utilizing a common catalytic mechanism [PDF]

Methylene-tetrahydropterin reductases catalyze the reduction of a methylene to a methyl group bound to a reduced pterin as C1 carrier in various one-carbon (C1) metabolisms.

Catalysts, autocatalysis and the origin of metabolism [PDF]

, 2019
If life on Earth started out in geochemical environments like hydrothermal vents, then it started out from gasses like CO2, N2 and H2. Anaerobic autotrophs still live from these gasses today, and they still inhabit the Earth's crust.

Deep Borehole Heat Exchangers -A Conceptual Review [PDF]

, 2020
Borehole heat exchangers are used for transforming a rock mass into an underground heat storage. Usually, their depth does not exceed 200 m, but some extend to a depth of almost 3000 m. Underground heat storages can operate as part of heating and cooling
