Researchers Launch Coating That Protects Cotton From Flame And Water

In china a team of researchers have introduced a triple layer coating that makes cotton waterproof and fire resistant as well as self cleaning.The researchers Shanshan Chen , Xiang Li, Yang Li and Junqi Sun from Jilin University found a way to extend the life of fire retardants and hit on an idea to formed water resistant materials.

They dipped a strip of cotton into different chemicals such as a binding agent "polyethylenimine" to stuck the chemicals into the strip of cotton, then dipped into a fire retardants known as ammonium polyphosphate and at the end they dipped it into ethanol and silsesquioxane solution which work as a seal against water.

Then they exposed both strips, treated as well as untreated, to flame.The treated cotton released a gas that cut off the oxygen supply and blasts out fires in a few seconds.While the other strip burns up quickly.The first layer allows waterproofing that remain on cotton strip after 1000 times rubbing.The second layer of hydrophobic molecules act as a self-healing, fills the gaps where the first layer is damaged.

British Scientists Generate Electricity With Urine

British scientists at the University of the West of England in Bristol, have revealed a toilet which create electricity with urine, that could be used to provide electricity in distant areas such as refugee camps.British scientists with aid agency Oxfam developed this urinal toilet.The Bill and Melinda Gates Foundation was funded this project "Urine tricity."

"It is always a challenge to light inaccessible areas far from a power supply," explained Andy Bastable, Head of Water and Sanitation at Oxfam.This invention is a great step to future.It is very difficult to live in a camp without light.Invention of this technology is a big sucess for scientists.

According to Ioannis Ieropoulos, who is a research team leader, a single unit costs approx £600 to install and supply electric power.It contains bacteria that break urine's chemicals during this process energy release in the form of electricity then stored on a capacitor in a fuel cell.

"The microbial fuel cells (MFC) work by employing live microbes which feed on urine for their own growth and maintenance," explained Ieropoulos."The MFC is, in effect, a system which taps a portion of that biochemical energy.

"This technology is about as green as it gets, as we do not need to utilise fossil fuels and we are effectively using a waste product that will be in plentiful supply," said Ieropoulos.

Earlier in 2013 the University of West of the England has displayed a urine powered cell to charge a smartphone.

Ocean Cleanup Project to Remove Wastes From Sea Surface

 A 19 year old aerospace engineering student at the Delft University of Technology, Boyan Slat has introduced a plan to clean the oceanic wastes from the surface of sea, this project is known the Ocean Cleanup Array.

Boyan Slat said, "it is a project to clean one-third of the total ocean surface plastic pollution or about 7,250,000,000 kilogrammes."This project could reduce the death rate of aquatic animals and also help out to reduce oceanic pollutants like PCB and DDT.

He posted in his website.“Plastic pollution costs governments, companies and individuals millions of dollars in damages per year, due to loss in tourism, vessel damages and (inefficient) beach clean-ups.”

Ocean Cleanup Array would have platform with booms to collect plastic waste due to the gyre current and by the flow of water wastes come to the platform then the trasher will recycle it.He said booms is better than nets because it covers a wider area and will save auqutic animals from catch.



The platforms would be stationary, will be self-supporting because of harnessing solar energy or currents.“According to current estimations – due to the plan’s unprecedented efficiency – recycling benefits would significantly outweigh the costs of executing the project,” Slat describes.The concept has the ability to remove 7,250,000,000 kg of world’s oceans plastic in just five years.This forcast is based on Ocean Surface Current Simulator (OSCURS) data.

This project is still under construction.If we want succee in this project we need to rise the importance of recycling, and reducing our consumption of plastic packaging,” said Slat.

London Announces New Technique For Pedestrian Safety

London has introduced the new technology for pedestrian to cross the raod more safely.The new pedestrian crossing sensors to help make it easier and safer for people to cross the road throughout the capital.

The Mayor of London "Boris Johnson" said the system has ability to adjust times of traffic signals automatically, traffic lights help the system to measure situations how many pedestrians are standing on the side of raod and need some more time.

The new technology "Pedestrian Split Cycle Offset Optimization Technique" or "pedestrian SCOOT", uses state-of-the-art camera technology to notice circumstances like how many pedestrians are waiting to cross the raods.If the cameras detect the number of pedestrians are waiting , they inform the signals that pedestrians want more "green light" time with the signaling system.

"The system would be bringing huge benefits to those waiting to cross the road where there is heavy pedestrian demand," managing director of surface transport at TfL, Leon Daniels said.

TfL made its Safe Streets for London in July, according to report on a road safety action plan for London 2020 and the main purpose of the report is to discrease the rate of people killed and badly injured on London's streets.

By 3D Printer Teen Develops Robohand for Boy(Video)

Mason Wilde is interested in 3-D printers and made a hand for a 9-year-old family friend. Matthew was born with only a thumb on his right hand, but a 3-D printer solves this problem.

Mason Wilde, a 16-year-old Louisburg High School junior, loaded blueprints from "Robohand" onto computers and using their 3-D printer at Johnson County Public Library made a prosthetic hand that is driven by the motion of the wrist.The hand opens if the wrist move up and the fingers close if move down.Mason Wilde wants eight hours to build this Robohand with the 3-D printer.

Jennifer said, “Every day, kids were asking him, ‘What happened to your hand, what happened to your hand,’ and I noticed it was wrecking his spirit,”. “Social stigma was starting to creep in on him.” 



Matthew's mother discovered a Robohand on the internet but it is so expensive approximately $18,000, his mother cannot afford this hand.Mason Wilde made ​​some changes to the hand developing the structures of the mechanism.

"When it is all done, to be able to say you gave a kid a hand, gave a kid the ability to grasp something and let him high five or hand shake, it is a pretty amazing feeling," Mason Wilde said.

"I actually have fingers. I didn't know what that felt like until now," Matthew said.

Matthew said, “I call it my toy tool, It is the future.”

"It has been a huge blessing. It has changed the conversation from, 'what happened to your hand?' to, 'oh my gosh! That is so cool.' That is huge when you are 9 and when you're a little bit different," Matthew's mom said.

Mason Wilde is looking into a career in the biomedical field and has inspired to start a non-profit to make prosthetics from 3-D printers for other children.

Inflatable Jungle Gym Gives New Experience

It is designed by Croatian-Austrian collective Numen/For Use, "string prototype" is a inflatable jungle gym made up of a grid of cables which are able to carry human weight.It is located near the Viennese countryside. The designer group that build "String jungle gym" is known for its large-scale interactive environments and made an inflatable building with a network of cables known as large geomatric inflatable object installation.


It works on the same pattern(principles) or rules like a bounce house.In jungle gym air is filled into the whole things of gym like wires to make the cables strong to climb on.When the body will inflate, the cables will pull and tight into a structure and able to support human body weight.


"Bodies entrapped in 3D grid, fly in unnatural positions throughout superficial white space, resemble Dadaist collages.Impossibility of perception of scale and direction results in simultaneous feeling of immenseness and absence of space." said designers who are working on the project.

A New Laser Makes Optical-Fiber Network 20 Times Faster

A team of researcher at Caltech has developed a new laser which has enough potential to increase the rate of data transmission in the optical-fiber network and replace the 40 years old fiber optic communications system.The study was published the week of February 10–14 in the online edition of the Proceedings of the National Academy of Sciences.

Light is capable of carrying vast amounts of information, approximately 10,000 times more bandwidth than microwaves.This new laser is noticeable due to its high spectral purity, spectral purity means close to operates on a single frequency.The closer (narrower) the tone, the more information laser light can carry and allows data to travel with the faster speed, so it is called faster internet.

Nowadays worldwide's optical-fiber network is known as the distributed-feedback semiconductor (S-DFB) laser.This distributed-feedback semiconductor (S-DFB) technology developed in the mid 1970s in Yariv's research group.The S-DFB laser manages to attain such spectral purity by using a nanoscale corrugation within the laser's structure that acts like a internal filter, discriminating against spurious "noisy" waves that effecting or making bad the ideal wave frequency.

The old S-DFB laser consists of continuous crystalline layers of materials called III-V semiconductors which absorb light causing a damage of spectral purity.The new laser technology still using the III-V material which stores the light in a layer of silicon, silicon does not absorb light.This new high spectral purity allows the laser to achieve range of frequencies Which is 20 times narrower the S-DFB laser.

Yariv and his team trying hard to improve laser technology and believe that the new laser will certainly improve the optical-fiber networking system.

Million year Old Footprints Have discovered In Britain

Scientists have discovered human footprints in England that are at least 800,000 years old.These footprints have been discovered when heavy seas washed sand off a beach in Happisburgh, Norfolk.

The footprints were discovered by a team of the British Museum, the Natural History Museum and Queen Mary University of London.

British Museum archaeologist Dr. Nick Ashton said published in the journal PLOS ONE "a tangible link to our earliest human relatives."

There are five different types of footprints.The footprints indicating adults, males and children walked through the beach.They are the earliest evidence of human ancestors and belong to first ever Britains.

The scientists and researchers believe the human who left the prints may have been related to ancestor known as Homo antecessor, or "Pioneer Man".

Natural History Museum archaeologist Chris Stringer said that 800,000 or 900,000 years ago Britain was "the edge of the inhabited world."

There are three sites in the world where older footprints found, 3.5 million years old in Tanzania and 1.5 million years old in Kenya, which are in Africa.

Isabelle De Groote, a specialist in ancient human remains at Liverpool John Moores University who worked on the find, said that "These individuals traveling together, may be that they were somehow related," and also said about the pattern of the prints.

The footprint will be a part of an exhibition, "Britain: One Million Years of the Human Story," open at the Natural History Museum on 13 February.

Beautiful Message

A woman said: ”while I was praying, my little daughter came to me and called me over and over again, but I didn't answer her of course because I was performing Salah. 

Her 6 years old brother came to her and told her: ”Shame on you!! How can you interrupt their dialogue!! Don’t you see that mom is talking to Allah!!” 

When I heard these words coming from my little son, I got chills throughout my body, I felt humiliation and shame of myself because I was in the presence of the Creator of the heaven and the earth, talking to Him and yet I was rushing through my salah. 

The words of my little son moved me so much that I remembered them every time I made Takbeer to perform Salah! 

Subhan Allah !!!.... The One Who sends wise messages through children to remind the adults. 

Share this wonderful message to also remind others!
