Super-thin, ultra-strong sheet glass produced in China

Published

on

BEIJING: A Chinese research institute has created super-thin, ultra-strong sheet glass that can resist the impact force of a car, running at 150 kilometers an hour.

Created by the Glass Research Institute in Bengbu City, Anhui Province, a unit of the technical engineering platform of China National Building Material Co., Ltd, the glass is only 0.12 millimeter thick, roughly as thick as a standard A4-sized piece of paper, which is 0.095 mm, according to Chinese media today.

The sheet glass, which came off the production line in April, is the thinnest one mass-manufactured using the float process, according to Cao. Modern windows are usually made from float glass, which is a sheet of glass made by floating molten glass.

Points to be noted: 

1) Created by the Glass Research Institute in Bengbu City, a unit of the engineering technical platform of China National Building Material Co., Ltd, the glass is only 0.12 millimeter thick — roughly as thick as a standard A4-sized piece of paper.

2) In an experiment led by leading researcher Cao Xin, a 55-gram steel ball was dropped from one meter to hit the glass, equivalent to the impact force made by a car at 150kph, and the glass remained intact.

3) The sheet glass, which came off the production line in April, is the thinnest one mass-manufactured using the float process, according to Cao.

4) Cao said the ultra-thin glass can be used widely in the electronic information sector, such as for screens for cellphones, computers and TVs. He said his next goal is to mass produce sheet glass at 0.1 millimeter thick.

5) Led by chief scientist Peng Shou, the research institute has made a series of strides in recent years, making 0.33-millimeter sheet glass in June 2014, 0.15-millimeter in April 2016 and now 0.12-millimeter.

6) It was previously just an illusion in the country to produce the material at less than half a centimeter. Reports say that the Chinese market used to rely on imports of the thin float glass, which made it very expensive.

Facebook users to get good safeguards!

Published

on

PARIS: Facebook users to get good safeguards, Facebook CEO Mark Zuckerberg said Thursday that he was rolling out the privacy controls demanded by European regulators to Facebook users worldwide because “everyone cares about privacy”.

Speaking at the VivaTech trade fair in Paris a day before new European data protection rules come into force Zuckerberg said Europe’s history had made its citizens particularly wary when it comes to data collection.

“There are specific points about history in Europe. If you’re a German citizen and you grew up here you’re worried about the Stasi (former East German secret police).

“That’s more recent in your memory than what we have in the US or other folks around the world.” But “everyone cares about privacy.

That’s not only here, that’s a global thing,” Zuckerberg said, confirming he would extend the protections demanded by the EU’s General Data Protection Regulation – including on facial recognition – to Facebook’s two billion users worldwide.

“We’ve been very clear that we’ll roll out the same controls all around the world,” he said, adding that “good regulation” would increase user trust in how tech giants use their data. 

Relevant piece published earlier:  The dreaded Islamic State militant group has made death threats to Facebook founder Mark Zuckerberg and Twitter CEO Jack Dorsey in a new video which shows their photos riddled with digitally added bullet holes, mocking the social media websites’ attempts to block terrorist content from their platforms. In the 25-minute video, the IS claim they are fighting back against efforts by the social media giants to wipe their platforms of accounts promoting terrorism. The video includes a direct threat to the tech entrepreneurs, branding them allies of the American “Crusader government”. Pictures of Zuckerberg and Dorsey can be seen being blasted with a hail of bullets in the amateur footage which emerged. In a separate slide, they also claim to have hacked more than 10,000 Facebook accounts, 150 Facebook groups, and more than 5,000 Twitter accounts.

Twin sports car-sized satellites to chase water changes on Earth

Published

on

TAMPA: A pair of identical, sportscar-sized satellites are poised to zoom around the Earth and track changes in water and ice, offering new insights into global warming and sea level rise, NASA said Monday.

Groundwater, oceans, lakes, rivers and ice sheets will be monitored by the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO), a joint mission between the US space agency and German Research Centre for Geosciences (GFZ).

The satellites are scheduled to blast off from Vandenberg Air Force Base in California on Tuesday at 12:47 pm Pacific time (1947 GMT). A SpaceX Falcon 9 rocket will propel the satellites to an orbit about 310 miles (500 kilometers) above the Earth. The pair will fly 137 miles (220 kilometers) apart, or about the distance from Los Angeles to San Diego.

NASA has spent $430 million on the mission, and Germany has spent about $91 million. The new pair of satellites will pick up where the first GRACE mission left off, having completed its 15-year mission in 2017. The first GRACE mission gave scientists a trove of data about the ever-dwindling ice mass.

China satellite heralds first mission to dark side of Moon

China satellite heralds first mission to dark side of Moon

BEIJING: China satellite heralds first mission to dark side of Moon, China launched a relay satellite today that will allow a rover to communicate with the Earth from the far side of the Moon during an unprecedented mission later this year.

The Queqiao (“Magpie Bridge”) satellite was blasted into space from the southwestern Xichang launch center in the pre-dawn hours, according to the China National Space Administration.

The satellite split from its carrier, a Long March-4C rocket, after 25 minutes and unfolded its solar panels and communication antennas, as it headed towards its destination, the CNSA said.

“The launch is a key step for China to realize its goal of being the first country to send a probe to soft-land on and rove the far side of the Moon,” Zhang Lihua, manager of the relay satellite project, was quoted as saying by the official Xinhua news agency.

The satellite will relay communications between controllers on Earth and the far side of the moon, where the Chang’e-4 lunar probe – named after the moon goddess in Chinese mythology – will be sent later this year.

Also known as the “dark side” of the Moon, the far hemisphere is never directly visible from Earth and while it has been photographed, with the first images appearing in 1959, it has never been explored.

The Chang’e-4 rover will be sent to the Aitken Basin in the lunar south pole region, according to Xinhua. It will be the second Chinese probe to land on the Moon, following the Yutu (“Jade Rabbit”) rover mission in 2013.
