These Japanese-made lamps effectively kill COVID-19 virus

Dr. Hiroki Ohge, Professor, Department of Infectious Diseases, Hiroshima University Hospital, and a group of researchers lead by Dr. Takemasa Sakaguchi, Professor, Hiroshima University Graduate School of Biomedical and Health Sciences, have completed a research study that demonstrates that irradiation with filtered 222nm UV-C light effectively reduces SARS-CoV-2 in an in vitro experiment. This is the first study conducted in the world on the efficacy of 222nm UV-C light against SARS-CoV-2, the virus causing COVID-19.

These lamps are targetted to be used in places like airports to help prevent the spread of bacteria and viruses.

In this study, Ushio’s Care222 UV-C disinfection module was placed 24 cm above the surface of the plates in which the viral samples were placed. The study showed that exposure to the 222nm light resulted in at least a 99.7% reduction of viable SARS-CoV-2 samples. The researchers concluded that the study demonstrated the effectiveness of 222nm UVC irradiation on SARS-CoV-2. The researchers further noted that the results suggest that the 222nm UVC technology could be used for infection prevention and control against COVID-19 both in occupied and unoccupied spaces.

The company notes that it is important to use filtered 222nm UV-C light in occupied spaces. Unfiltered 222nm UV-C lamps will emit radiation in the 230nm (UV-C) to 320nm (UV-B) range. Irradiation without blocking these higher wavelengths of light has been reported to cause erythema and damage to the cellular DNA at considerably lower levels than filtered 222nm light.

Ushio’s Care222 device features a specially designed bandpass filter that is based on groundbreaking research and technology developed by Columbia University and filters the longer UV wavelengths from the lamp. To know more about the product, watch the video below:

Specs comparison: Xiaomi Mi 10 vs Mi 10 Pro

03/31/2020

While it’s true that Xiaomi still has phones that offer capable performances without breaking the bank, the company is also going toe-to-toe with big players in the smartphone market.

Xiaomi has launched its flagship phones globally in the form of the Mi 10 and Mi 10 Pro. Obviously, the Pro variant will be loaded with better features and is the top variant among the three (including the entry-level Mi 10 Lite 5G).

Let’s take a quick look at the differences and similarities between the Mi 10 and Mi 10 Pro.

[supsystic-tables id=3]

The two phones are basically one in terms of general capabilities. Apart from colors, they both have the same form factor, display, processor used, and support for wireless charging. They even have the same main and selfie cameras.

Where they differ mainly, though, is in the rest of the camera department. The Mi 10 Pro is loaded with a tandem of zoom sensors comprising of its 8-megapixel hybrid zoom for subjects far away and a 12-megapixel optical zoom that comes in handy for portraits.

Its 108-megapixel main sensor is also a tad bit better than the mid-tier model since it carries an 8P lens vs the Mi 10’s 7P setup. It should technically produce sharper images but we still have to find out how much difference it makes.

Battery implementation is the next differentiator of the two flagship devices. The Mi 10 actually carries a larger capacity than the Mi 10 Pro but it features a faster wired charging with its 50W output. Wireless charging is rated at 30W for both handsets.

Finally, and of course, pricing is also different. The Xiaomi Mi 10 is tagged at EUR 799 (approx. PhP 44,700 or US$ 879) while the higher-end Mi 10 Pro is at EUR 999 (approx. PhP 56,000 or US$ 1,099).
