Transport is responsible for around 23% of energy-related carbon dioxide emissions globally. This is expected to double by 2050. Motor vehicles also put a burden on society, especially in urban environments where they are chiefly responsible for noise and air pollution. Electric vehicles (EVs) have been considered as critical technology for …
Read More »Nonlinear optical (NLO) materials have long been known to interact with light, to produce a nonlinear response. Nonlinear optical materials use nonlinear dependence of the refraction index on the applied electric field to produce other frequencies. This results in either harmonic generation or frequency shifting. The development of the field was …
