“Plasma” refers to a gas with a significant proportion of ionized molecules, which produce various excited ions, atoms, and molecules. Electrons liberated from ions and atoms are highly energetic and ...

Nonlinear optics is the branch of photonics that studies material responses wherein the induced polarisation is not directly proportional to the applied electromagnetic field. In these media, intense ...

A team of researchers from the Keck School of Medicine of USC and California Institute of Technology (Caltech) have developed a potential new way to measure a person's stroke risk that is ...

Optical properties and spectroscopy have become integral to modern biomedical applications by providing non‐invasive methods for tissue analysis, diagnostics and therapeutic guidance. Through the ...

A new book on infrared spectroscopy picks up where all previous books leave off. Jena-based scientist PD Dr. Thomas Mayerhöfer has written the first book on infrared spectroscopy that explains spectra ...

Normal, physiologic, autoregulated blood flow to the brain is central to essentially all aspects of human health, and when it goes wrong, the results can be catastrophic. However, due to our thick ...
