Yuan Zhimin emphasized that the corona virus that spreads in the world did not originate from his institution.
Wuhan Virology Institute finally spoke up over the allegations that the new corona virus, Covid-19, was deliberately made by his laboratory and leaked and spread.Deputy Director of the Wuhan Virology Institute, Yuan Zhiming, said the accusation was a “conspiracy theory” that unsettled the public. He denied the virus was man-made.Yuan asserted, the laboratory in his institution has a high level of security. So it is impossible for the corona virus to come from his laboratory.
Plus, none of his staff were infected with the corona virus. So Yuan said that it was very unlikely that Covid-19 would come from his institution.”As people who carry out virus studies, we clearly know what kind of research takes place at the institute and how the institute manages viruses and samples. As we said from the start, it is not possible for this virus to come from us,” Yuan said.Yuan understood why many people connected this plague to the laboratory. For one thing, this new type of corona virus was first identified in Wuhan.He also stressed this was a misleading rumor.

Research Results on LED Ultraviolet Problem Claimed to Kill Corona Virus
Pandemic outbreak makes all people in the world try to do whatever it takes to prevent their bodies from contracting Covid-19 disease. Moreover, the number of infected cases worldwide has touched the figure of 2 million people.Experts are also racing against time to find vaccines, drugs, and ways for healthy people not to be infected with the corona virus.
Reporting from Sciencedaily.com , research currently being conducted to find ways to prevent transmission of the corona virus was made by UC Santa Barbara’s Solid State Lighting & Energy Electronics Center (SSLEEC) and its member companies.Researchers at this institute are developing ultraviolet LEDs that have the ability to decontaminate surfaces – air and water – that have come in contact with the SARS-CoV-2 or Corona Covid 19 virus.

Focus on the Effectiveness of Ultraviolet Rays
Doctoral research researcher, Christian Zollner revealed, he focused on advancing ultraviolet LED lighting technology for sanitation and purification purposes. He added that there was already a market for UV-C disinfection products in the medical context.At present, indeed many researchers have turned to the power of ultraviolet light to inactivate the new corona virus. As a technology, ultraviolet light disinfection has been around for a long time. And in the meantime, its efficacy against the spread of SARS-CoV-2 has not shown results.

UV-C Light Is Able To Deactivate Microbes
UV light shows a lot of hope for getting rid of the corona covid-19 virus.SSLEEC member company, Seoul Semiconductor in early April reported that corona virus sterilization (Covid-19) could reach 99.9 percent in 30 seconds with their UV LED products.Their technology is currently being adopted for automotive use – where UV LED lights function to sterilize vehicle interiors that are not in use.
It should be noted that not all UV wavelengths are the same. UV-A and UV-B which we get a lot from the sun – actually have quite important uses.However, there is a rare ultraviolet light, UV-C which can purify air and water can also deactivate microbes. UV-C can be produced only through man-made processes.”UV-C rays in the range of 260 – 285 nm which are most relevant for disinfection technology are also dangerous for human skin. For now, research is still being done without human objects,” said Zollner.

SSLEEC Scientists Research UV-C LEDs
Actually WHO has warned against using ultraviolet disinfection lamps to clean hands or other skin areas. Because exposure to UV-C rays can cause burns and eye damage.Before the Covid-19 pandemic spread around the world, scientists at SSLEEC were already working on advancing UV-C LED technology.
This electromagnetic spectrum is a relatively new frontier for lighting solid objects. UV-C light is more commonly produced through mercury vapor lamps. According to Zollner, technological advancements are needed for UV LEDs to reach their potential in terms of efficiency, cost, reliability and service life.According to Zollner, using silicon carbide as a substrate enables the growth of high-quality UV-C semiconductor materials that are more efficient and cost-effective than using sapphire.

Still Awaiting Development
Emergence of the Covid-19 pandemic caused many parties to compete in searching for vaccines, therapies and medicines. At present we are still doing disinfection, decontamination, and isolation as a temporary solution used throughout the world.In addition to UV-C for water sanitation purposes, UV-C light can be integrated into the system. So that it will minimize costs, be free of chemicals, and be convenient for cleaning public, retail, private, and medical spaces.
For now, Zollner and colleagues are still waiting for the development of this pandemic. Research at UC Santa Barbara has also slowed down to minimize contact during a pandemic.”After continuing research activities at UC Santa Barbara, we will continue our work to improve the AlGaN / SiC platform. We hope that the platform will produce the most efficient UV-C rays in the world,” Zollner said.
