The semiconducting and metallic phases of conjugated polymers
Miguel Lagos
Recently a variety of -conjugated polymers have been developed and essayed for a number of applications such as organic light-emitting diodes, organic field-effect transistors,…
Theoretical approach to the ductile fracture of polycrystalline solids
Miguel Lagos, César Retamal, Rodrigo Valle
It is shown here that fracture after a brief plastic strain, typically of a few percents, is a necessary consequence of the polycrystalline nature of the materials. The polycrystal…
Fourier transform spectrometry without Fourier analysis of the interferogram
Miguel Lagos, Rodrigo Paredes, Cesar Retamal
It is shown here that precision is gained by analyzing the interferometric spectra directly from the interferograms, with no previous Fourier transformation to put them in the stan…
High Precision Energy Measurements from the Analysis of Wide Spectral Features. Application to the fluorescence of YAG:Ce3+
Miguel Lagos, Rodrigo Paredes, César Retamal
Advantage is taken of a complete and precise experimental study of the luminescent properties of yttrium aluminium garnet doped with Ce, previously accomplished by other authors, t…
Why old tires are still being preferred as dock bumpers in harbours
Miguel Lagos
The usage of old tires as dock and tugboat bumpers has been a common practice from long ago, proving to be safe for docking even the largest freighters. The reaction force and stor…
Evidence of a two--dimensional grain sliding regime in the plastic deformation of micron and sub--micron films
Miguel Lagos, Víctor Conte, Michel Ignat
Copper and aluminium sub-micron films are structured as columnar arrays of grains traversing the entire film, and hence are virtual two-dimensional polycrystalline solids. A closed…
