On February 8th, the Japan Industrial Technology Research Institute announced an invention of the institute, which used light-emitting diodes (LEDs) to produce ultraviolet light with bactericidal effect. Compared with the mercury germicidal lamps currently in use, such LED ultraviolet lamps have the advantages of low power consumption, high safety, and small volume.
Due to the rampant global epidemic diseases such as H1N1 influenza A, the market for sterilization equipment in society and life is growing. The sterilization methods currently used are high temperature sterilization, chemical sterilization, and ultraviolet sterilization. Among these sterilization methods, ultraviolet sterilization of mercury lamps is an important sterilization method. Ultraviolet sterilization is effective not only for heat-resistant bacteria, but also has no side effects of chemical sterilization, and can directly act on bacterial DNA to inhibit its proliferation. In particular, DNA absorbs light having a wavelength of about 260 nm, and the bactericidal effect is remarkable. At present, most of the sterilization methods used are low-pressure mercury lamps that emit ultraviolet light of 256 nm wavelength. However, if mercury leaks, it will cause damage to the environment. In addition, the mercury lamp device itself is also very large, so the market requires the development of a UV sterilization device that does not use mercury and is light and simple.
LED lighting is mostly used in energy-saving light sources such as street decoration, and LED ultraviolet light has not yet been realized. However, a small number of LEDs used in gallium nitride materials emit ultraviolet light. Due to technical bottlenecks, there are technical difficulties in manufacturing short-wavelength light. LEDs with wavelengths below 350 nm have not appeared on the market.
The research team led by Yamazaki Satoshi and Makino Junqing of the Institute successfully developed a near-practical diamond LED with a luminous power of 0.3 mW through the transformation of artificial diamond quality and the improvement of electronic devices. The research team used artificial diamonds to make 0.5. The millimeter-diameter LED was irradiated with ultraviolet light to the E. coli coated on the tray with an LED to confirm the death of Escherichia coli. The illumination distance is 2 mm and the illumination range is 1 cm.
In the future, the research team plans to improve the luminous intensity and verify the short-time sterilization effect through the transformation of electronic devices, so as to be applied to oral sterilization and tableware sterilization as soon as possible.

There are plenty of benefits for using usb type c cable For starters, the port is reversible! But that is only the tip of the cable. And like ice bergs, there is much more than meets the eye in type c cables. They allow for faster transfers, charging, 4K monitor output and more.
Needless to say we will have to start populating our living spaces with USB 3.1 Type C and accessories.It measures in at 1.8 meters of length and can handle USB 2.0 charging, as well as up to 60W of fast charging power. Not bad at all.
