CdS doped TiO2 nanotube composite was fabricated by chemical bath deposition, and was characterized by the structural, spectral and photoelectrochemical properties. The results of the structural and spectral properties showed that CdS particles were successfully deposited onto the surface of TiO2 nanotube. It is demonstrated that CdS doped TiO2 nanotube composite improved the light harvesting ability. Power conversion efficiency of about 0.32% was observed. This value is about 2.9 times higher than that of pure TiO2 nanotube. The CdS doped TiO2 nanotube composite possesses relatively higher photocatalytic activity and photodegradation efficiency than that of pure TiO2 nanotube under UV light irradiation, and the degradation efficiency of methyl orange was about 42% at UV intensity of 32 W.
Demystifying Light Levels for Cannabis Grows
As more and more investors, opportunists and growers are jumping onto the green rush that is the cannabis industry right now there is also a big influx of folks who are learning as they go. Lighting is a major purchase for this industry as a big margin of growers still prefer the better climate control and security of growing indoors and even those who choose to grow in a greenhouse are finding that no matter where they are in the world, they still need to supplement lighting to continue producing a high-quality...
LED Lighting and Compatibility Issues with Legacy Dimming Systems
LED Lighting and Compatibility Issues with Legacy Dimming Systems LED technology is being adopted by numerous businesses around the world. Its energy saving benefits, long lifespan and modern features have won over individuals who are looking for reliable lighting solutions. But in order for the transition to gain full acceptance by consumers and commercial sectors, LEDs have to be able to support legacy dimming systems and controls. LED Dimming Definition and Standards Dimming is a crucial aspect of...
Types of UV Light for Different Applications
Types of UV Light for Different Applications Ultraviolet (UV) radiation was discovered in 1801 when the German physicist Johann Wilhelm Ritter observed that invisible rays just beyond the violet end of the visible spectrum darkened silver chloride-soaked paper more quickly than violet light itself. He called them "oxidizing rays" to emphasize chemical reactivity and to distinguish them from "heat rays", discovered the previous year at the other end of the visible spectrum. In 1878 the effect of short-wavelength...
The Importance of Explosion Proof Lights in Cleanrooms
Cleanrooms are pushing the limits of industrial manufacturing and scientific research programs. For professionals, the rooms provide a predictable environment with low levels of stray pollutants, germs, dust and chemical vapors. Activities conducted in cleanrooms are carried out with greater precision and safety. Class 1 Division 1 Explosion Proof Lights Explosion proof lights are typically installed in cleanrooms to prevent sparks from igniting flammable or combustible elements in the hazardous location....
