In 1980 Binnig et al. reported tunneling measurements on Nb-doped SrTiO3, and interpreted their results as indicating two-band superconductivity in the bulk of SrTiO3. However: (1) Effective masses determined from tunneling results in the normal stat

A recent paper and a preprint both claim records for the lowest carrier concentration at which superconductivity has been observed. However colleagues in Australia and I found evidence for superconductivity at concentrations of the order of at least

An unusual published energy versus wave vector curve extending to the zone edge determined by ARPES in 5% La-doped SrTiO3 is interpreted using mixed-polaron theory. After modification of the theory to permit tight-binding bare energy bands and anisot

I shall discuss three small systems in which I think room-temperature superconductivity has been observed. These are: 1. Narrow channels through films of oxidised atactic polypropylene (OAPP) and other polymers. 2. Some multiwalled carbon nanotubes o

Reasons have been found for thinking that the minimum diameter of channels of a given length to support superconductivity at room temperature through films of oxidised atactic polypropylene (OAPP) is considerably larger than found in a model for Bose

Bipolaron energies are calculated as a function of wave vector by a variational method of Gurari appropriate for weak or intermediate coupling strengths, for a model with electron-phonon interactions independent of phonon wave vectors and a short-ran

Attention is drawn to the fact that some publications state or imply incorrectly that the BCS-Bose gas transition was first studied by Leggett in 1980, whereas I published a paper on this subject in 1969. Attention is also drawn to evidence from coll

There are strong reasons from dc and pulsed-current measurements, and from thermal conductivity results, for thinking that narrow channels through films of oxidised atatic polypropylene (OAPP) are superconducting at room temperature. It is thought th

A simple model is used to analyse published results on large room-temperature diamagnetism for two films of oxidised atactic polypropylene (OAPP) at low magnetic fields. The model involves induced currents expected in circular closed loops of superco
