A Start Up Company From Japan To Launch ‘Love Satellites’

If this service receives a good response, Warspace would expand its business and will send out more commemorative objects into space.

A Japanese start-up linked to the University of Tsukuba is set to launch small satellites with commemorative titanium plaques carrying love messages into space by the end of 2019, the company said on Monday.

Those interested would be able to engrave messages of their choice on the plaques, which would be 1.8 centimeters long and 0.8 centimeter wide, set to be carried to space aboard the satellites and orbit around the Earth for around two years before being destroyed, Efe reported.

Around 10 centimeters in size, the CubeSat satellites would be able to carry up to 600 pure titanium plaques and would be transported to the International Space Station (ISS) by a rocket of the Japan Aerospace Exploration Agency.

In the ISS, the astronauts stationed there will take photographs of the ultra-small satellite which would be then sent to the couples to prove that their messages have reached space, Warspace CEO Toshihiro Kameda said.

The start-up had planned to offer this service exclusively to the couples getting married at a hotel in Tsukuba, in Ibaraki prefecture, for the price of $270, but in the face of growing demand it decided to expand its offer and set up an online order facility in September.

Although they have not determined the number of people interested in the service yet, couples from Japan, the US and Taiwan have contacted the company.

The mini satellites and the plaques would be destroyed after two years by burning up when they come in contact with Earth’s atmosphere, said Kameda, a professor who teaches the mechanics of materials at the University of Tsukuba.

If this service receives a good response, Warspace would expand its business and will send out more commemorative objects into space which would later return to Earth, the head of the project said. (IANS)

New Technology That Can Clean Water Twice As of Now

Novel technology cleans water using bacteria

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.

The new technology is capable of identifying and quantifying different kinds of cyanobacteria, or blue-green algae, as a threat to shut down water systems when it suddenly proliferates. Pixabay

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.

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)
