Analogous to most new methods in science, photoacoustic spectroscopy (PAS) grew out of
an advance in technology, in this case the dramatic improvement in novel light sources …

The present review is intended to encompass the English language heat transfer papers
published in 1999. The papers have been placed into a number of subject categories. While …

This paper describes the design and optimisation of the photoacoustic (PA) cell for
nondestructive PA spectroscopy. The results of numerical calculations of the acoustic …

Today, non-destructive analysis techniques play an important role in industrial applications
and scientific, as well as technological research. Photoacoustic method is one of such non …

The monolayer of carbon atoms in a hexagonal lattice is called graphene. It is a monoatomic
layer of graphite. The stacking of hexagons one over the other creates a variety of layers. We …

Today, non-destructive analysis techniques for solids are playing an important role in

La detección de sustancias peligrosas, tóxicas y contaminantes es de gran interés en la
actualidad debido al impacto que tienen estas para la salud humana, el medio ambiente y …

This paper describes the construction and testing at room temperature of a resonant
photoacoustic cell which may be used to carry out photoacoustic measurements of opaque …

The thermoelastic mechanism for laser generation of acoustic waves in liquids is presented
first of all. The amplitude of the acoustic waves excited by this mechanism is so small that …
