Solid-state reactions – observation and recording in real time

Real time observation of the formation of hollow nanostructures through solid state reactions.

We demonstrate the formation of hollow nickel germanide nanostructures of Ni-Ge core-shell nanoparticles by solid state reactions. The structural evolutions of nickel germanide hollow nanostructures have been investigated in real-time ultrahigh vacuum transmission electron microscopy (UHV-TEM). Annealed above 450 °C, the nonequilibrium interdiffusion of core and shell species occurred at the in...

Manganese Antimonate: Facile solid state synthesis, characterization and its application for Biginelli reactions

Nanostructured Mn2Sb2O7 powders were synthesized via stoichiometric1:1 Mn:Sb molar ratio solid state reaction at different reactions temperatures for 8 h using MnSO4.H2O and Sb2O3 as raw materials. The synthesized materials were characterized by powder X-ray diffraction (PXRD) technique. Structural analyses were performed by the FullProf program employing profile matching with constant scale fa...

Real-Time Time-Frequency Two-Dimensional Imaging of Ultrafast Transient Signals in Solid-State Organic Materials

In this review, we demonstrate a real-time time-frequency two-dimensional (2D) pump-probe imaging spectroscopy implemented on a single shot basis applicable to excited-state dynamics in solid-state organic and biological materials. Using this technique, we could successfully map ultrafast time-frequency 2D transient absorption signals of β-carotene in solid films with wide temporal and spectral...
