SUMMARY
The environmental scanning electron microscope (ESEM) allows the examination of specimens in a gaseous environment. It is based on an integration of efficient differential pumping with a new design of electron optics and detection systems. Backscattered, cathodoluminescence and X-ray detectors can be designed to fit and to perform optimally in the ESEM. The secondary electron signal can be detected with the gaseous detector device, which is a new multipurpose detector. Insulating, uncoated, wet and generally both treated or untreated specimens can be studied.read more

Comparative organic geochemistries of soils and marine sediments
John I. Hedges,J.M Oades +1 more
TL;DR: In the ocean, nitrogen-rich microorganisms produce and recycle most organic matter in the water column, from which degraded particles rain onto the underlying sea floor and the buried organic matter joins the geological cycle, surfacing again millions of years later as kerogen uplifted in continental rocks as discussed by the authors.

An overview of polymer latex film formation and properties.
TL;DR: Surfactant-free homopolymer model colloid latices, favoured in academic studies, together with latices containing surfactants whose redistribution can influence film properties, and the more complex copolymer, blended, core-shell and pigmented systems needed to satisfy a full range of film properties are all considered.

Opportunities and challenges in liquid cell electron microscopy
TL;DR: Recent advances that have made it possible to do liquid cell electron microscopy are reviewed, which opens up the possibility of studying problems such as the changes inside a battery during operation, the growth of crystals from solution, or biological molecules in their native state.

From food structure to texture
TL;DR: In this article, a multidisciplinary approach is proposed for studying the relationship between food structure and texture perception, combining sensory research, physiology studies and research into food physicochemical characteristics.
Journal ArticleDOI
A history of scanning electron microscopy developments: towards "wet-STEM" imaging.
TL;DR: The main advances that contributed to development of the wet-STEM technique are highlighted, which extends the scope of SEM as a high-resolution microscope, relatively cheap and widely available imaging tool, for a wider variety of samples.

Foundations of Environmental Scanning Electron Microscopy
TL;DR: In this article, the authors present new theoretical derivations and computations, explain and review experimental findings, survey existing literature and collect data and information relevant to environmental scanning electron microscope or microscopy (ESEM), and create the foundations for further use and development of ESEM.

Theory of the Gaseous Detector Device in the Environmental Scanning Electron Microscope
TL;DR: A survey of previous works in related fields, coupled with current experience in the environmental scanning electron microscope (ESEM) is presented in this paper, which allows the examination of specimens in the presence of a gaseous environment.

Charge neutralisation of insulating surfaces in the SEM by gas ionisation
TL;DR: In this article, a theory is presented in which the elimination of charging artefacts on uncoated insulating surfaces in the scanning electron microscope by a low-pressure ambient gas is taken to be due to ionisation of the gas.
