This is the first comprehensive review on methods and materials for use in optical sensing of
pH values and on applications of such sensors. The Review starts with an introduction that …

Colorimetric sensors play a crucial role in promoting on‐site testing, enabling the detection
and/or quantification of various analytes based on changes in color. These sensors offer …

There has been a consistent increase in output related to the development and application
of optical chemical sensors since∼ 1980. The rise of activity was linked to the major …

Chemical analysis based on colour changes recorded with imaging devices is gaining
increasing interest. This is due to its several significant advantages, such as simplicity of …

Continuous monitoring of oxygen concentration is of great importance in many different
areas of research which range from medical applications to food packaging. In the last three …

Luminescent films have received great interest for chemo-/bio-sensing applications due to
their distinct advantages over solution-based probes, such as good stability and portability …

Nitrogen (N) fertilization in agricultural soils is the largest anthropogenic source of nitrous
oxide (N 2 O) emissions, but the underlying mechanism of the varied response of N 2 O …

Eutrophication and metal pollution are global environmental problems. The risk of metal
pollution is high in the eutrophic lakes because of high mobility of metal in sediments …

The highly sensitive optical detection of oxygen including dissolved oxygen (DO) is of great
interest in various applications. We devised a novel room‐temperature‐phosphorescence …

The divergent effects of straw returns on nitrous oxide (N 2 O) emissions from soil require
elucidation of the underlying mechanisms and factors that explain the inconsistency in in …
