The environmental scanning electron microscope (ESEM) is a scanning electron microscope (SEM) that allows for the option of collecting electron micrographs of specimens that are wet, uncoated, or both by allowing for a gaseous environment in the specimen chamber.
Environmental scanning is usually used at the start of a futures project. It aims at broad exploration of all major trends, issues, advancements, events and ideas across a wide range of activities. Information is collected from many different sources, such as newspapers, magazines, Internet, television, conferences, reports, and also science ...
Horizon scanning is "the systematic examination of potential threats, opportunities and likely future developments which are at the margins of current thinking and planning’ and, continuing, horizon scanning ‘may explore novel and unexpected issues, as well as persistent problems or trends."
Environmental analysis is the use of examination and statistical methods to study the chemical and biological factors that determine the quality of an environment. [1] The purpose of this is commonly to monitor and study levels of pollutants in the atmosphere, rivers and other specific settings. [ 2 ]
The gaseous detection device (GDD) is a method and apparatus for the detection of signals in the gaseous environment of an environmental scanning electron microscope (ESEM) and all scanned beam type of instruments that allow a minimum gas pressure for the detector to operate.

The concept of environmental scanning (Aguilar, 1967) describes a process whereby the environment in which an organization operates is systematically scanned for relevant information. The purpose is to identify early signals of possible environmental change and to detect environmental change already underway.
LP-EM systems of both open and closed type have been developed for all three main types of electron microscopy, i.e., transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), and scanning electron microscope (SEM). [9] Instruments integrating liquid-phase SEM with light microscopy have also been developed.
