This article describes the influence of heterogeneous surface morphology on analytical signal formation in total-reflection X-ray fluorescence analysis (TXRF). We propose a theoretical consideration of the dependence of X-ray fluorescence lines on the mechanism of new phase nucleation and growth on a foreign low-density substrate...

We have combined a commercial confocal scanning head to a Ti:sapphire laser and to an inverted microscope for the detection of single-molecule fluorescence of various dyes by two-photon excitation. The fluorescent probes were spread on chemically etched glass slides by spin-coating and we have developed three independent criteria to discriminate the fluorescence signal emitted by single molecules from that of the aggregates and the background...

In biomedical research, non-destructive imaging of small laboratory animals is a prerequisite. Non-invasive X-ray microtomography (?CT) was applied to visualize growth and development in rats and mice...

Temperature at a constant heat flux was measured on an integral resistor sample that showed apparent interfacial mobility. Initial measurements were made using infrared, optical, and scanning electron microscopies...

There have been no corresponding confocal laser scanning microscopy (CLSM) studies of dental caries or comparisons with the changes seen by other established imaging techniques. This study deals with the comparative findings obtained from light microscopy, microradiography and CLSM of ground sections from permanent human teeth with early fissure enamel caries...

In the mid 1990s the internet began to impact the commercial world of microscopy. While the subsequent buzz, hype and investment never reached the manic proportions of the fast moving consumer goods or leisure sectors, there was a definite feeling of excitement that a new way of doing business was emerging...
