Scanning Electron Microscopy

Secondary electron micrograph of an isolated seta from a Lower Cambrian filter-feeding arthropod; the discovery of such fossils has established the presence of an active zooplankton in the earliest Palaeozoic (scale bar 10 um) ©NJ Butterfield
Our SEM is equipped with secondary and backscattered electron imaging.
Cathodoluminescence images can also be produced. Energy-dispersive X-ray detector is available. This can be operated with an ultra-thin window for detection of light elements (2<10).

For any quantitative chemical analyses the electron microprobe should be used.

Transmission Electron Microscopy

When examined by transmission electron microscopy, the silicate mineral kalsilite can be seen to have a lamellar intergrowth texture on a scale of a few hundred Ångstroms.
The TEM is used for sample characterisation, particularly in the study of the formation of microstructures associated with displacive and order/disorder phase transitions.

International team head to Papua New Guinea to measure volcanic carbon degassing

Sep 01, 2016

An international team of scientists is traveling to the islands of Papua New Guinea this September to study degassing from active volcanoes in remote jungles there. Some of these volcanoes are among the most active on Earth, ejecting a significant proportion of global volcanic gases into the atmosphere.
