Optical methods for bacterial detection and characterization
The development of these optical methods requires both an understanding of the biology of bacteria and how bacteria interact with light. In Sec. II, we give a brief overview of the biology ofbacteria with a strong focus on the properties that can potentially produce a characteristic or quantifiable signal, we describe standard bacteria …

What is the Purpose of a Gas Diffusion Layer (GDL)?
Typical applications that use GDLs consist of Polymer Electrolyte Membrane Fuel Cells (PEMFC) and Direct Methanol Fuel Cells (DMFC). When a GDL is coated with a catalyst it is then referred to as a Gas Diffusion Electrode(GDE), which is sometimes sold or installed separately from the Membrane or MEA.

Spectrophotometer: Principle, Parts, Types, and Uses
A spectrophotometer is a laboratory equipment that can measure the number of photons (the intensity of light) absorbed after passing through the solution of the sample. It can also detect the concentration of the solution by measuring the intensity of detected light. "Spectrophotometry" is the method used by the spectrophotometer for …

Cell Wall
The main component of the plant cell wall is cellulose, a carbohydrate that forms long fibers and gives the cell wall its rigidity. Cellulose fibers group together to form bundles called microfibrils. Other important carbohydrates …
The Blank in Photometry
Determining blank, or zero, values is an important step in all photometric measurements. It serves the calibration of the photometer, which is thus set to "zero". The blank value should encompass all those components which are included in the measurement of the sample, with the sole exception of the substance to be analyzed.
