The efficiency of a heterogeneous catalyst depends on the nature and number catalytically active sites, but these are often inhomogeneous. One possible solution is to construct site-isolated catalysts in which most, if not all, sites structurally uniform well-defined. Metal phosphides sulfides form with distinct crystal structures based range component stoichiometries. Hence, incorporating comp...

The control and understanding of the chemical and physical properties of quantum dots (QDs) demands detailed surface characterization. However, probing the immediate interface between the inorganic core and the ligands is still a major challenge. Here we show that using cross-polarization magic angle spinning (MAS) NMR, unprecedented information can be obtained on the surface ligands of Cd3P2 a...

Transition metal phosphides exhibit high catalytic activity toward the electrochemical hydrogen-evolution reaction (HER) and resist chemical corrosion in acidic solutions. For example, an electrodeposited CoP catalyst exhibited an overpotential, η, of -η < 100 mV at a current density of -10 mA cm-2 in 0.500 M H2SO4(aq). To obtain a chemical description of the material as-prepared and also while...

Introduction: Among the magmatic iron meteorites, group IVB irons have some unusual characteristics, such as high bulk Ni (15-18 wt%), high refractory elements (e.g., Ir), low volatile elements (e.g., Ga, Ge) [1, 2], fast cooling rates and a small parent body [3, 4]. IVB irons do not have a Widmanstatten pattern as in lower Ni IIIAB or IVA irons. Instead, IVB irons have a plessite structure wit...
