Positron is the only probe that can detect individual atomic vacancies and small and large
vacancy clusters induced by irradiation with remarkable sensitivity, providing information …

Positron is an excellent probe of lattice defects in solids. A thermallized positron delocalized
in lattice can be trapped at open volume defects, eg vacancies, dislocations, grain …

New conductive materials for tissue engineering are needed for the development of
regenerative strategies for nervous, muscular, and heart tissues. Polycaprolactone (PCL) is …

Abstract Sr 1-x La x TiO 3 (SLTO) ceramics with colossal permittivity were fabricated by
conventional solid-state reaction method. The point defects of pure STO and SLTO ceramics …

To study the vacancy-solute-atom interaction, diluted Al-In and Al-Sn alloys with 0.005 and
0.025 at.% indium/tin cast from very high purity elements were investigated by positron …

In recent years, superconducting radio-frequency (SRF) cavities have been considered as
candidates for qubits in quantum computing, showing longer photon lifetimes and, therefore …

High-resolution digital coincidence Doppler broadening spectrometer equipped with two
high-purity Ge detectors and two-channel 12-bit fast digitizer was developed and tested in …

The main objective of the present paper is to communicate a study of defects behavior in
zirconia-based nanomaterials—pressure-compacted yttria-stabilized zirconia (YSZ) …

The development of intrinsic vacancies in SnSe single crystals was investigated as a
function of annealing temperature by means of positron annihilation spectroscopy …

Emerging metal-halide perovskites (MHPs) have shown advanced charge transport
properties suitable for application in solar cells, photodetectors, and many more. While the …
