Smog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution—some visible, some invisible.
Generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment is considered air pollution.
Air pollution through the ozone, nitrogen dioxide, volatile organic compounds (VOCs) and particulate dust puts a burden on the environment and impairs human health.
Especially now, during the lazy and hazy days of the summer months air pollution is being worse than in the winter time.
Days are longer, there is more sunlight and generally more stability in the atmosphere which leads into stagnant air. The air doesn’t move, it just “sits and cooks”.
Emissions that cause air pollution come from different sources, like power plants, cars, planes, ships etc. To limit emissions, they need to be measured.
Heraeus Noblelight develops analytical lamps that enable cost-efficient and reproducible precise analysis.
Photoionisation detection lamps (PID) for example are most commonly used in VOC gas detection, in gas chromatography (GC) and sample ionization for mass spectrometry.
Whilst high-intensity Deuterium lamps are the ideal choice for high-end HPLC instruments or UV-Vis spectrophotometer.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale
Researchers from the Institute of Organic Chemistry and Biochemistry of the CAS (IOCB Prague), Institute of Physics of the CAS (IP CAS) and Palacký University...
For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
