Defective graphene decorated with TiO2 nanoparticles as negative electrode in Li-ion batteries

  In this work, the performance of novel negative electrodes for Li-ion batteries based on defective graphene synthesized via a scalable thermal exfoliation of graphite oxide and decorated with TiO2 nanoparticles is investigated. Titania polymorphs are interesting as battery electrode … Continue reading

Degassing and phase transitions with temperature in melanophlogite

Melanophlogite (type I clathrate) has a microporous framework of corner sharing SiO4 tetrahedra, which can host guest gases. Here, a multi–analytical approach has been employed to understand the phase transitions with temperature and the degassing behaviour of a melanophlogite sample, which … Continue reading

Structural investigation of N,N’-methylenebisacrylamide via X-ray diffraction assisted by crystal structure prediction

This gallery contains 1 photo.

The crystal structure of N,N’-methylenebisacrylamide was determined through the geometry optimization of the molecular unit with density functional theory and conformational analysis, and then through the calculation of the packing via a crystal structure prediction protocol, based on lattice energy … Continue reading

Li12C60: A lithium clusters intercalated fulleride

This gallery contains 1 photo.

We reported the structural analysis of the highly-doped lithium fulleride Li12C60, performed using low temperature neutron powder diffraction. Although the main reflections could be initially indexed with a fcc cell, Monte Carlo Simulated Annealing suggests an unusual monoclinic arrangement for … Continue reading

Fullerenium Salts: A New Class of C60-Based Compounds

We report on the preparation and characterization of a fullerenium salt in the solid state, where the fullerene is in the 2+ oxidized state. To succeed in this long-standing challenge, we exploit the oxidizing power of one of the strongest … Continue reading
