The discovery of magnetism by the ancient Greeks was enabled by the natural occurrence of
lodestone–a magnetized version of the mineral magnetite. Nowadays, natural minerals …

The piezochromic properties of spin-crossover complexes have been recognized for a long
time, with increasing pressure favouring the low spin state due to its smaller volume and …

The European XFEL delivers up to 27000 intense (> 1012 photons) pulses per second, of
ultrashort (≤ 50 fs) and transversely coherent X-ray radiation, at a maximum repetition rate …

The presence of carbonates in inclusions in diamonds coming from depths exceeding 670
km are obvious evidence that carbonates exist in the Earth's lower mantle. However, their …

Synchrotrons and free electron lasers are unique facilities to probe the atomic structure and
electronic properties of matter at extreme thermodynamical conditions. In this context,'matter …

The pressure effects on the optical and structural properties of NiWO4 have been studied
experimentally and theoretically. The fundamental bandgap decreases with a pressure …

Siderite (FeCO3) is an iron-bearing carbonate mineral that is the most abundant
sedimentary iron formation on Earth. Mineralogical alteration of four siderite samples …

Diamond-anvil cell (DAC) experiments focusing on the solubility of carbonates and aqueous
carbon speciation at subduction zones require pressure monitoring with sensitive …

Iron (II) oxalate dihydrate FeC2O4× 2 H2O—humboldtine is not only an important synthetic
intermediate, but also a key building block for the preparation of various advanced materials …

The vibrational and electrical transport properties of natural siderite are systematically
investigated by means of in-situ Raman spectroscopy and alternating current impedance …
