But unprotected exposure to the sun's ultraviolet (UV) rays can cause damage to the skin, eyes, and immune system. It can also cause cancer. There are other contributing factors such as heredity and ...

The first results of the ETH Zurich and ANSTO collaboration focused on silicon carbide (SiC) devices have been reported in ...

The bistability characteristics of GaN/AlN resonant tunneling diodes (RTDs) grown on a sapphire substrate were investigated. The RTDs exhibit bistability characteristics with high and low resistivity ...

The UV and visible electronic transitions of a series of red-emitting dyes based on the triangulenium motif are investigated. We resolve overlapping features in the spectra and assign the orientation ...

You won't get sunburned if you don't feel the sun on your skin: UV rays that cause sunburns cannot be felt. The feeling of heat is caused by the sun's infrared radiation, not the UV.

Wear Sunglasses Look for lenses labeled ‘100% UV protection’ or “UV400” to block both UVA and UVB rays. Additionally, choose wraparound or oversized frames that offer better coverage and prevent UV ...

The significant role of relativistic effects in altering the NMR chemical shifts of light nuclei in heavy-element compounds has been recognized for a long time; however, full understanding of this ...
