*If you learn how to use atomic absorption spectroscopy (AAS), you can do accurate and reliable chemical research. But it takes practice and concentration to fully grasp its basic ideas. Understanding ...

The basic principles of AAS can be expressed as follows. Firstly, all atoms or ions can absorb light at specific, unique wavelengths. When a sample containing copper (Cu) and nickel (Ni), for example, ...

This live, instructor-led course provides an introduction to the technique of Atomic Absorption Spectroscopy (AAS). The course covers the initial choice of analytical set-up through to method ...

Over the past few years, it has become possible to confine and guide light in micrometre-scale, hollow-core waveguides based on photonic-crystal structures, such as photonic-crystal fibre (HC-PCF) 6, ...

Atomic force microscopy (AFM) and infrared (IR) spectroscopy have emerged as complementary techniques that enable the precise characterisation of materials at the nanoscale. AFM provides ...

For more than thirty years, heavy metals have been considered potential toxic environmental contaminants. It is a fact that most of today’s environmental challenges revolve around the determination of ...

Fossil fuels are widely used in automobiles, industry, and power plants, but due to excessive use they are depleting at a rapid rate. This has prompted a search for renewable, sustainable, and ...
