the bonding of electronic products, uvled point light source has low energy consumption, small footprint, light weight and other advantages.The characteristics of uvled point light source are introduced as follows:1. low energy consumption, mercury-free, ozone-free...
But such experiments present challenges to researchers doing live cell imaging: not only is UV light unable to pen-etrate deep enough into living tissue for some applications, but short-wavelength, high-energy UV radiation is highly photo-toxic to cells. Infrared (IR) light, whose wavelengths ...

In most cases, a hybrid eclipse starts as an annular eclipse because the tip of the umbra falls just short of making contact with Earth; then it becomes total because the roundness of the planet reaches up and intercepts the shadow's tip near the middle of the path, then finally it retur...
the molecular properties of Rh7 indicated that it is a UV light-sensitive pigment with bistable character. However, it exhibited an unusual broad absorption band that was not observed previously, suggesting that this property is one of the important clues to the elucidation of the function of Rh...
Visible light falls in the range of the EM spectrum between infrared (IR) and ultraviolet (UV). It has frequencies of about 4 × 1014 to 8 × 1014 cycles per second, or hertz (Hz) and wavelengths of about 740 nanometers (nm) or 2.9 × 10−5 inches, to 380 nm (1.5 × 10−...
UV (Ultraviolet) LEDs: Emitting ultraviolet light, these LEDs find applications in sterilization, forensic analysis, curing, and medical devices. IR (Infrared) LEDs: Emitting infrared light, these LEDs are used in applications like remote controls, sensors, night vision devices, and communication syst...
of GG with glycidyl methacrylate [7], displays enhanced water solubility (so that solutions at 1–2% can be prepared in water at room temperature) and is capable of crosslinking mediated by monovalent and divalent cations, as well as by ultraviolet light (due to the methacrylate substituent)....
of wavelengths is known as theelectromagnetic (EM) spectrum. The spectrum is generally divided into seven regions in order of decreasing wavelength and increasing energy and frequency. The common designations are radio waves,microwaves,infrared(IR), visible light, ultraviolet (UV),X-raysandgamma-...
