Interspecies interactions mediated by conductive minerals in the sediments of the Iron rich Meromictic Lake La Cruz, Spain
espanolLa laguna de La Cruz puede considerarse como un analogo biogeoquimico de los ambientes marinos en la Tierra primitiva, porque su columna de agua, muy escasa en sulfato pero rica en metano y…
Recyclable Naturally Derived Magnetic Pyrrhotite for Elemental Mercury Recovery from Flue Gas.
- Environmental ScienceEnvironmental science & technology
The control of Hg0 emission from coal-fired plants by the recyclable pyrrhotite was cost-effective and did not have secondary pollution, and the ultralow concentration of gaseous Hg2+ in the flue gas was concentrated to high concentrations of gases during the regeneration process, which facilitated the centralized control of mercury pollution.
Quantifying the origin of inter-adsorbate interactions on reactive surfaces for catalyst screening and design.
- ChemistryPhysical chemistry chemical physics : PCCP
The large magnitude of inter-adsorbate interactions as well as their strong dependence on lattice strain demonstrate the need for using coverage-dependent adsorption energies for more accurate screening, for example for strained catalytic systems like core-shell and overlayer structures.
Dynamics of point defect formation, clustering and pit initiation on the pyrite surface

Field-Control, Phase-Transitions, and Life’s Emergence
- PhysicsFront. Physio.
A causal link of life’s macroscopic irreversible dynamics to the microscopic reversible laws of statistical mechanics is indicated via the “functional-takeover” of a soft magnetic scaffold by organics.

From volcanic origins of chemoautotrophic life to Bacteria, Archaea and Eukarya
- BiologyPhilosophical Transactions of the Royal Society B: Biological Sciences
The theory of a chemoautotrophic origin of life in a volcanic iron–sulphur world postulates a pioneer organism at sites of reducing volcanic exhalations that gave rise to two major strands of evolution: cellularization and emergence of the genetic machinery.
Abiotic synthesis of organic compounds from carbon disulfide under hydrothermal conditions.
It is concluded that the abiotic formation of aliphatic straight-chain and cyclic polysulfides is possible under hydrothermal conditions and warrants further studies.

It is a consequence of this hypothesis that the postulated cycle cannot exist as a single isolated cycle but must be a member of a network of concatenated homologous cycles, from which all anabolic pathways appear to have sprung.
Biomineralization of ferrimagnetic greigite (Fe3S4) and iron pyrite (FeS2) in a magnetotactic bacterium

THE ability of magnetotactic bacteria to orientate and navigate along geomagnetic field lines is due to the controlled intracellular deposition of the iron oxide mineral, magnetite (Fe3O4)1,2. The…
Magnetic iron-sulphur crystals from a magnetotactic microorganism
- Materials ScienceNature
IN all magnetotactic microorganisms studied so far, the geomagnetic field is detected by magnetic particles with a permanent magnetic moment. These are crystallites enveloped by a membrane that forms…
Submarine hot springs and the origin of life
The popular hypothesis that life arose in hydrothermal vents is examined, based on a number of misunderstandings concerning the organic chemistry involved, which would not allow synthesis of organic compounds but would decompose them, unless the exposure time at vent temperatures was short.
