The Story of Graphene

Fascination with this material stems from its remarkable physical properties and the potential applications these properties offer for the future. Although scientists knew one atom thick, two-dimensional crystal graphene existed, no-one had worked out how to extract it from graphite.

Scientists cook up material 200 times stronger than steel out of soybean oil

Many production techniques involve the use of intense heat in a vacuum, and expensive ingredients like high-purity metals and explosive compressed gases. Now a team of Australian scientists has detailed how they turned cheap everyday ingredients into graphene under normal air conditions. They said the research, published today in the journal Nature Communications, may open up a new avenue for the low-cost synthesis of the highly sought-after material.

Physicists patent detonation technique to mass-produce graphene

Forget chemicals, catalysts and expensive machinery-a Kansas State University team of physicists has discovered a way to mass-produce graphene with three ingredients: hydrocarbon gas, oxygen and a spark plug. Their method is simple: Fill a chamber with acetylene or ethylene gas and oxygen. Use a vehicle spark plug to create a contained detonation. Collect the graphene that forms afterward.

Why graphene hasn’t taken over the world...yet - prof petrik demonstration




To demonstrate the ease of production of the HRCM, mainly responsible for purifying water, professor did small-scale demo. The HRCM produced in the demo could in itself be used in 10 filters and last 5 yrs. The same sorbet will be produced in factories and due to its ease of production it will be massively available making the technology economical as well.
As one of the other advantages the attendees got to see a demo of how oil spillage can be cleared using the black sorbet.

To prove the effectiveness of the filter firstly a demonstration of filtering water out of cocoa cola was done. HRCM Bucket (Balti) Filter the sp. Filter for India was used as a filter for the demonstration.
Secondly water polluted with all the impurities like sand, oils, solid, etc was used for the demonstration. It amazed the guests that water was clear and absolutely pure for drinking in no time. As all the presentations were done in front of the eyes and guests themselves were volunteers it proved there are no deceptions and this technology is indeed revolutionizing.
The entire reception of the technologies was quite welcoming and it got lot of people interested from business point of view. Next invention which professor showcased was antistoke compound. He showed that how the antistoke compound be helpful in catching the forfeited currency notes. The banking sector can safeguard themselves and control crime against duplicated currency notes.

Is This New Super Carbon Better Than Graphene?

Scientists have been searching for schwarzites for decades, here’s how their discovery could change our world.

Generating carbon schwarzites via zeolite-templating

Nanocarbons can be characterized by their curvature—that is, positively curved fullerenes, zero-curved graphene, and negatively curved schwarzites. Schwartzites are fascinating materials but have not been synthesized yet, although disordered materials with local properties similar to schwarzites (“random schwarzites”) have been isolated.

Simulations suggest graphene’s elusive cousin may become a reality

“Now, Berend Smit’s laboratories at the Ecole Polytechnique Fédérale de Lausanne (EPFL) and the University of California, Berkeley, have developed a computational method which suggests that some kinds of zeolite-templated carbons (ZTCs), including some that have been attempted in labs, are in fact Schwarzites. Smit credits the project’s success to collaboration between chemists and mathematicians in his group.”

Long-sought carbon structure joins graphene, fullerene family

“UC Berkeley chemists have proved that three carbon structures recently created by scientists in South Korea and Japan are in fact the long-sought schwarzites, which researchers predict will have unique electrical and storage properties like those now being discovered in buckminsterfullerenes (buckyballs or fullerenes for short), nanotubes and graphene.”

Taking GRAPHENE out of the Lab - The Current State [2019]

Taking GRAPHENE out of the Lab - The Current State [2019]

We’ve all been following the evolution of Graphene for years now or ever since it came into light with the 2010 Nobel prize.
But graphene has been around for longer than that, or at least 63 years in the making. Nine years after graphene took the world by storm, many of us are still wondering about where are all of the things that we were promised, made with graphene.

The Strength of GRAPHENE Explained

The Strength of GRAPHENE Explained - In this video I discuss about Graphene and where does the 10x stronger or 200x stronger than steel comes from.

Enjoy!

World's Lightest Solid!

Aerogels are the world's lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission. The focus of this video is silica aerogels, though graphene aerogels are now technically the lightest.

At one point Dr. Steven Jones literally held the Guinness World Record for making the lightest aerogel and therefore lightest solid. If you're interested in learning more about aerogels, let me know in the comments as there is a potential trilogy in the works...

Huge thanks to Dr. Stephen Steiner and the crew at Aerogel Technologies. To find out more or buy your own aerogel sample, check out:

What's Graphene And Why It'll Soon Take Over The World - nano technology.




The demonstration is how to produce Graphene HRCM by the method of cold destruction of carbon laminated compounds into carbon clusters, graphenes. GrapheneCl2O7 is produced by a special reaction on NaCl in platinum electrolyzers. A retardant is added to Cl2O7 to slow down the reaction by avoiding explosion. The reaction is autocatalytic chain reaction. It was claimed that this method of Graphene production is only known to Prof. Petrik. Carbon material produced by cold destruction of stratified carbon compounds, mostly consisting of graphenes and having high activity to pressing is named High Reactivity Carbon Mixture [HRCM]. It consists of graphenes, various web type carbon structures in rolls, nanotubes, branching nanotubes, nanofractals, etc, which form homogenous carbon mass as a result of chaotic concretion possessing tremendous specific surface and high chemical activity. Abnormal sorption properties of HRCM can be explained by the fact that carbon atoms at the graphene periphery are not saturated have increased chemical activity and can be bound to many compounds in order to compensate free valence. Graphene has unique properties -very high sorption ability, very light 2 kg/m3, high thermal conductivity, high electrical conductivity very strong- 200 times steel.
Prof.Petrik informed that industrial method for production of graphenes is patented in 56 countries, including the USA and countries of the European Union.The method enables to produce HRCM in industrial quantities under field conditions without necessity of special hardware.It was claimed that HRCM is a new substance of a certain class having no analogues in the world by physical, chemical, functional and economic characteristics as well as by ecological purity, versatility and variety of spheres of application.

Graphene _ The Future ("STRONGEST MATERIAL IN THE WORLD")

Graphene is a semi-metal with a small overlap between the valence and the conduction bands. It is an allotrope of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It is the basic structural element of many other allotropes of carbon, such as graphite, diamond, charcoal, carbon nanotubes and fullerenes.

This monster plant is trying to take over. What if we let it?

Silicon Valley is home to tech giants, venture capital…and a years-long battle between an invasive species, a tiny bird, and a bunch of scientists trying to decide what counts as “nature.” We put on the biggest boots we could find and headed out to the strange salt flats of the San Francisco bay to check it out.

NOTE: All footage of U.S. and California Fish and Wildlife Service land was obtained via special agreement with those agencies. Filming on said land requires a Special Use Permit. Additionally, launching, landing, or operating an unmanned aircraft (drone) from or on lands and waters administered by the California and U.S. Fish and Wildlife Services is prohibited unless special permits are obtained.

Science Documentary: Graphene, Nanomaterials, a Documentary on Nanotechnology

Science Documentary: Graphene, Nanomaterials, a Documentary on Nanotechnology

We use nanotechnology and nanomaterials every day or our lives. They are in sporting goods, microelectronics, automotive goods, biomedical devices, etc.

Graphene is a nanomaterial that comes from the oldest and cheapest material, called graphite. Graphene is a none atom thick layer of carbon. To put it in perspective, graphite is made of billions of layers of carbon, if you take one layer of that graphite, you have graphene. Graphene is very flexible, light and transparent; and it is 300 times stronger than steel, which makes graphene the strongest material known to man. The biggest problem with graphene, is that it is difficult to make.

Graphene was first discovered by taking scotch tape and a pencil with graphite, then scribbling on the piece of scotch tape, then by continuously separating the scotch tape over and over, you get a thinner piece of graphite. until eventually you reach about an atom thickness and you then have graphene. But this process, would be very difficult to produce graphene commercially. By using magic solvents, we can produce billions of graphene sheets in a half hour. Now scientists have improved that figure to one kilogram of graphene an hour. Graphene is not the only layered material in nature, so by exploring these different materials, we can produce totally different nanomaterials with completely different properties, because they would be made by different atoms.

There are several useful products that can be produced from nanomaterials, including printable and flexible electronics. Nanotechnology can also be used to make solar panels more affordable. Although, at the present time, solar panels are being produced, at a price that many people are happy to pay , for the output they produce. The problem is that when they are placed outside they become damaged from the sunlight. What happens is that the solar panels power output begins to slowly degrade up to 30% from its initial value, which is a very significant loss, and greatly affects the cost of the solar panel.

In microelectronics, a problem was discovered that was traced to ionized copper being affected by a light source. Since copper is positively charged, and positive and negative charges attract each other, if we put a material with a negative charge on the surface of the solar cell we can remove the effects caused by the harmful copper.

In the study of advanced nanotechnology, there are two engineering methods. The standard method and the exploratory method. Products engineered using the standard methodology must be able to be described and modeled, and must be able to be manufactured. In the standard model, ideas must be concrete, whereas in the exploratory method, parametric designs are more acceptable and are open to designs that are not yet understood.

We have seen winged flight and optical imaging, for example, and we have artificial systems that mimic them. The materials may be different but the systems are the same. In the molecular world, there are also several biological systems with there artificial counterpart. The biological systems use enzymes, whereas the artificial system uses digital information to create several new materials which can be used for making bulletproof vests with silk fiber.

Carbon nanotubes built this bizarre ultrablack material

Carbon nanotubes are a lot like graphene: both are super-hyped materials that haven’t changed the world the way we hoped they would. At least, not yet. But while producing nanotubes, one research team accidentally found something else: one of the blackest materials on the planet. We explore how nanotubes help comprise Vantablack, and how ultrablack materials are actually used around the world.

Why Haven’t Hydrogen Vehicles Taken Over the World Yet?

Hydrogen fuel cells are promoted as efficient and carbon free, but what happened to hydrogen cars?

Why a Half Degree Rise in Global Temperature Would Be Catastrophic -

Gas guzzlers reborn: Why your next car could run on hydrogen

“Now, there are signs of a comeback. A recent survey of more than 900 global automotive executives by consulting firm KPMG found that 52 percent rated hydrogen fuel cell vehicles as a leading industry trend. Japan has announced plans to put 40,000 hydrogen vehicles on the road in the next five years, and South Korea 16,000. Germany wants to have 400 refuelling stations for hydrogen vehicles by 2025 and California has already opened 35.”

Fuel Cells

“Fuel cells work like batteries, but they do not run down or need recharging. They produce electricity and heat as long as fuel is supplied. A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte. A fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode.”

Toyota plans to expand production, shrink cost of hydrogen fuel cell vehicles

“TOYOTA CITY (Reuters) - Toyota Motor Corp (7203.T) is doubling down on its investment in hydrogen fuel cell vehicles, designing lower-cost, mass-market passenger cars and SUVs and pushing the technology into buses and trucks to build economies of scale.”

Forget Graphene - Borophene may take over the world

Stronger and more flexible than graphene, a single-atom layer of boron could revolutionize sensors, batteries, and catalytic chemistry.


This brave new graphene-based world has yet to materialize. But it has triggered an interest in other two-dimensional materials. And the most exciting of all is borophene: a single layer of boron atoms that form various crystalline structures.


The reason for the excitement is the extraordinary range of applications that borophene looks good for. Electrochemists think borophene could become the anode material in a new generation of more powerful lithium-ion batteries.

Chemists are entranced by its catalytic capabilities. And physicists are testing its abilities as a sensor to detect numerous kinds of atoms and molecules.


Borophene has a short history. Physicists first predicted its existence in the 1990s using computer simulations to show how boron atoms could form a monolayer.

The Age of Graphene: Samsung's Revolutionary Battery Technology

Pre-historic times and ancient history are defined by the materials that were harnessed during that period.
We have the stone age, the bronze age, and the iron age.
Today is a little more complex, we live in the Space Age, the Nuclear Age, and the Information Age.
And now we are entering the Graphene Age, a material that will be so influential to our future, it should help define the period we live in.
Potential applications for Graphene include uses in medicine, electronics, light processing, sensor technology, environmental technology, and energy, which brings us to Samsung’s incredible battery technology!
Imagine a world where mobile devices and electric vehicles charge 5 times faster than they do today.
Cell phones, laptops, and tablets that fully charge in 12 minutes or electric cars that fully charge at home in only an hour.
Samsung will make this possible because, on November 28th, they announced the development of a battery made of graphene with charging speeds 5 times faster than standard lithium-ion batteries.
Before I talk about that, let’s quickly go over what Graphene is.
When you first hear about Graphene’s incredible properties, it sounds like a supernatural material out of a comic book.
But Graphene is real! And it is made out of Graphite, which is the crystallized form of carbon and is commonly found in pencils.
Graphene is a single atom thick structure of carbon atoms arranged in a hexagonal lattice and is a million time thinner than a human hair.
Graphene is the strongest lightest material on Earth.
It is 200 times stronger than steel and as much as 6 times lighter.
It can stretch up to a quarter of its length but at the same time, it is the hardest material known, harder than a diamond.
Graphene can also conduct electricity faster than any known substance, 140 times faster than silicone.
And it conducts heat 10 times better than copper.
It was first theorized by Phillip Wallace in 1947 and attempts to grow graphene started in the 1970s but never produced results that could measure graphene experimentally.
Graphene is also the most impermeable material known, even Helium atoms can’t pass through graphene.
In 2004, University of Manchester scientists Andre Geim and Konstantin Novoselov successfully isolated one atom thick flakes of graphene for the first time by repeatedly separating fragments from chunks of graphite using tape, and they were awarded the Nobel Prize in Physics in 2010 for this discovery.
Over the past 10 years, the price of Graphene has dropped at a tremendous rate.
In 2008, Graphene was one of the most expensive materials on Earth, but production methods have been scaled up since then and companies are selling Graphene in large quantities.

What is graphene? Uses of graphene and propetties of graphene

Graphene: Made in Manchester

Graphene is the world's thinnest material.

The two dimensional material was first isolated by Professor Andre Geim and Professor Kostya Novoselov at The University of Manchester. Graphene is the thinnest material known and yet also one of the strongest. It conducts electricity as efficiently as copper and outperforms all other materials as a conductor of heat. Graphene is almost completely transparent, yet so dense that even the smallest atom helium cannot pass through it.

The uses of graphene are limitless and because of its multi-functional properties, graphene can be used in thousands of different applications.

Sporting goods, technology and motor vehicles are just a few of the applications that can be improved with graphene. The constant research being done everyday is quickly proving that graphene is truly the material of the future.

New Batteries Could Last a Decade With Minimal Upkeep

The batteries are designed to store wind and solar energy for later use. They're non-toxic, non-corrosive and could significantly reduce the cost of production.

Lithium-Ion Battery Inventor Introduces Fast-Charging, Noncombustible Batteries

A team of engineers led by 94-year-old John Goodenough, professor in the Cockrell School of Engineering at The University of Texas at Austin and co-inventor of the lithium-ion battery, has developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage.

BU-204: How do Lithium Batteries Work?

Lithium is the lightest of all metals, has the greatest electrochemical potential and provides the largest specific energy per weight. Rechargeable batteries with lithium metal on the anode could provide extraordinarily high energy densities; however, it was discovered in the mid-1980s that cycling produced unwanted dendrites on the anode. These growth particles penetrate the separator and cause an electrical short. The cell temperature would rise quickly and approach the melting point of lithium, causing thermal runaway, also known as 'venting with flame.'

Has lithium-battery genius John Goodenough done it again? Colleagues are skeptical

Researchers have struggled for decades to safely use powerful-but flammable-lithium metal in a battery. Now John Goodenough, the 94-year-old father of the lithium-ion battery, is claiming a novel solution as a blockbuster advance. If it proves out, the invention could allow electric cars to compete with conventional vehicles on sticker price. The improbable solution, described in a new paper from Goodenough and three co-authors, has drawn intense interest from leading science and technology publications.
