This paper reviews the most important sensor-based methods that are commonly utilized for
detecting and measuring hydrogen sulfide (H 2 S) gas. It identifies a quite comprehensive …

First a few words about the genesis of this review, which is alreadythe third on this subject in
this series (Al, A2). I tried to preserve as much as possible of the scope and the format of the …

Research activity in chemical gas sensing is currently directed towards the search for highly
selective (bio) chemical layer materials, and to the design of arrays consisting of different …

Alongshore sediment transport that is driven by waves is generally assumed to smooth a
coastline. This assumption is valid for small angles between the wave crest lines and the …

Two recent topics important for advancing gas sensor technology are introduced.
Semiconductor gas sensors have been developed so far on empirical bases but now a …

The kinetics of interaction of nitrous oxides (NOx) with SnO2 sensor surfaces were
investigated. It is shown that NO, similar to CO, undergoes a simple reducing interaction with …

This paper describes the development and use of microdevices and microarrays in chemical
sensor research. The surface-micromachined “microhotplate” structure common within the …

Microfabrication processes for chemical and biochemical sensors are reviewed. Standard
processing steps originating from semiconductor technology are detailed, and specific …

Microfabrication technologies initially developed for integrated electronics have been
successfully applied to batch-fabricate a wide variety of micromechanical structures for …

Chemical and biological sensors have found their niche among modern analytical
instruments when real-time determination of the concentration of specific sample …
