Elucidation of the chemical changes that take place during the ageing of polyethylene by weathering can be accomplished by infrared (IR) spectroscopy. Accelerated ageing was applied to the most representative low density polyethylene (LDPE) found in

Optical filters for the infrared to the UV spectral range made of porous silicon are produced and tuned by modulating the current density during the etching process. Using such filters in an optical sensor it is possible to do quantitative absorption
