Combined high-resolution transmission electron microscopy, selected area electron diffraction and parallel electron energy loss spectroscopy are used to characterise carbon nano-phases found embedded in fused quartz. These appear after implantation o

Domain structure in perovskite ferroelectric particles of PbTiO3 and BaTiO3 was studied. The fact that most observed domains are 90° domains implies that elastic energy is the controlling influence on domain configuration. With decreasing particle s

We describe experiments which demonstrate that carbon atoms introduced into a fused-silica substrate by means of MeV ion implantation can, after suitable annealing, form nanocrystalline diamond. Unlike other methods of creating diamond, the coalescen

Barium titanate ultra-fine particles prepared by sol–gel (SG) and stearic acid-gel (SAG) methods are studied by high-resolution transmission electron microscopy (HRTEM). Physical property measurements showed that the barium titanate particles made

A prototype model is introduced for self-replicating octahedral shell structures. The structure is inherently aperiodic and unable to grow like a normal crystal. Conditions under which this growth mechanism may become favored energetically are discus

The analogy between carbon nanotubes and synthetic imogolite, an aluminosicate of stoichiometry (OH)3Al2O3SiOH, having a tubular structure of external diameter 2.4 nm and internal diameter 0.9 nm, is examined. High-resolution transmission electron mi

The film morphology and defect structure of ferroelectric bismuth titanate thin films are studied by high resolution transmission electron microscopy. As-grown and RTA-processed thin films have similar defect structures, consisting of stacking faults
