Recyclable Naturally Derived Magnetic Pyrrhotite for Elemental Mercury Recovery from Flue Gas.
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.
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.
Field-Control, Phase-Transitions, and Life’s Emergence
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.
Magnetism, FeS Colloids, and Origins of Life
A number of features of living systems, reversible interactions and weak bonds underlying motor-dynamics; gel-sol transitions; cellular connected fractal organization; asymmetry in interactions and

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
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.
