A budget version of the newly-launched BlackBerry KEY2, which is likely to be named BlackBerry KEY2 Lite or KEY2 LE, may be launched at the upcoming IFA 2018 in Berlin, Germany.
“TCL- the manufacturer behind the BB brand has sent out ‘save the date’ invites for an IFA event. It will be held on August 30 and while it offers no official details on what will be announced, there is only one rumoured phone in our database — the BlackBerry KEY2 LE,” GSM Arena reported late on Monday.
Similar to Key2, the physical keyboard experience would be the smartphone’s main USP.
“KEY2 will have less processing power on tap — the Snapdragon 660 chipset will be swapped out for a 636 and RAM capacity will drop to 4GB (still better than the Keyone),” the report added.
The device is expected to replace the 12+12MP dual camera set-up of KEY2 with a 12MP+5MP model.
The KEY2 Lite is faintly reminiscent of the BlackBerry Q5, which was a cheaper alternative to the flagship Q10. Like the KEY2 Lite, the Q5 had a playful, colorful aesthetic, and lower-spec internals, according to The Next Web portal. (IANS)
Researchers, led by one of Indian-origin, have developed a new technology that can clean water twice as fast as commercially available ultrafiltration membranes, an advance that brings hope for countries like India where clean drinking water is a big issue.
According to a team from the Washington University in St. Louis, more than one in 10 people in the world lack basic drinking water access, and by 2025, half of the world’s population will be living in water-stressed areas.
The team led by Srikanth Singamaneni, Professor at the varsity, developed an ultrafiltration membrane using graphene oxide and bacterial nanocellulose that they found to be highly efficient, long-lasting and environment-friendly.
The membrane technology purifies water while preventing biofouling, or build up of bacteria and other harmful micro-organisms that reduce the flow of water.
For the study, published in the journal Environmental Science and Technology, they used bacteria to build such filtering membranes.
The Gluconacetobacter hansenii bacteria is a sugary substance that forms cellulose nanofibres when in water.
The team then incorporated graphene oxide (GO) flakes into the bacterial nanocellulose while it was growing, essentially trapping GO in the membrane to make it stable and durable.
They exposed the membrane to E. coli bacteria, then shone light on the membrane’s surface.
After being irradiated with light for just three minutes, the E. coli bacteria died. The team determined that the membrane quickly heated to above the 70 degrees Celsius required to deteriorate the cell walls of E. coli bacteria.
While the bacteria are killed, the researchers had a pristine membrane with a high quality of nanocellulose fibres that was able to filter water twice as fast as commercially available ultrafiltration membranes under a high operating pressure.
When they did the same experiment on a membrane made from bacterial nanocellulose without the reduced GO, the E. coli bacteria stayed alive.
While the researchers acknowledge that implementing this process in conventional reverse osmosis systems is taxing, they propose a spiral-wound module system, similar to a roll of towels. Also Read: India Gets Assistance of Rs 3,420 Crore From Japan
It could be equipped with LEDs or a type of nanogenerator that harnesses mechanical energy from the fluid flow to produce light and heat, which would reduce the overall cost.
If the technique were to be scaled up to a large size, it could benefit many developing countries where clean water is scarce, the researchers noted. (IANS)
