Acoustic attenuation due to transformation twins in CaCl2: Analogue behaviour for stishovite [PDF]
CaCl2 undergoes a tetragonal (P42/mnm) to orthorhombic (Pnnm) transition as a function of temperature which is essentially the same as occurs in stishovite at high pressures.

Heterovalent, Homometallic Rings: Synthesis, Optical, and EPR Studies of {TiIV7TiIII} Complexes
Chemistry – A European Journal, EarlyView.A new class of heterovalent, homometallic complexes is reported, based on cyclic {TiIV7TiIII} cores with oxide and carboxylate bridges between nearest neighbors. The clusters show Class II mixed‐valent behavior at room temperature, but are valence localized at low temperature.

Gel-Sol Synthesis of Rutile Nanoparticles
Acta Chimica Slovenica, 2014 Titanium dioxide (TiO2) rutile nanoparticles were synthesized at temperatures below 100 °C using a gel-sol process that provides control of the final particles’ characteristics, such as the nanoparticle size, morphology, crystal structure and ...

Synthesis of bio-active titanium oxide coatings stimulated by electron-beam plasma
Open Chemistry, 2014 Advantages of the electron-beam plasma (EBP) for production of bioactive titanium oxide coatings were experimentally studied. The coatings were synthesized in EBP of oxygen on the surface of plane titanium substrates.

Chemistry – A European Journal, EarlyView.We propose a novel displacement‐assisted approach for temperature‐programmed desorption (TPD), allowing for the detection of reactive intermediates of on‐surface reactions. We demonstrate the approach by investigating the temperature‐dependent ring fusion reactions (cyclodehydrogenations) of tetraphenylporphyrin on Cu(111), revealing the quantitative ...

Rutile (U-Th)/he Thermochronology [PDF]
, 2019 Rutile is a relatively common phase in metamorphic and to a lesser extent igneous rocks. Its development as a (U-Th)/He thermochronometer would allow its application to decipher thermal histories in a broader range of lithologies than currently ...

EcoEnergy, EarlyView.An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)
