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.”

Top 10 Uses for the World's Strongest Material

Graphene is the world's new wonder material. It's the thinnest electronic material ever invented, consisting of a layer of carbon atoms just a single atom thick -- the atoms are arranged in a hexagonal pattern. It weighs almost nothing, coming in at only 0.77 grams for a square meter. But it's no lightweight. Graphene is 100 times stronger than steel of the same thickness. It conducts both heat and electricity better than copper, and has outstanding optical and mechanical properties. If it could be produced on an industrial scale, graphene might revolutionize fields such as electronics and even body armor.

A Lucky Lab Accident Results in Bucketloads of Graphene

Apparently, when it comes to making graphene, the 21st-century 'miracle material' taking manufacturing by storm, you can do things the hard way or the fun way. The hard ways - and there are dozens - all have their own complications. Some require high temperatures and long 'cooking' times, others require the use of hazardous chemicals like sulfuric acid or hydrazine. The easy way comes from physicists at Kansas State University, and the process is admirably straightforward: Fill a steel containment unit with oxygen and hydrocarbon gas, detonate it with the spark and, voila, a bucketload of soot-like graphene. Scrape it out and repeat.

Graphene sieve turns seawater into drinking water

Graphene-oxide membranes have attracted considerable attention as promising candidates for new filtration technologies. Now the much sought-after development of making membranes capable of sieving common salts has been achieved. New research demonstrates the real-world potential of providing clean drinking water for millions of people who struggle to access adequate clean water sources. The new findings from a group of scientists at The University of Manchester were published today in the journal Nature Nanotechnology. Previously graphene-oxide membranes have shown exciting potential for gas separation and water filtration.

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.

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 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.

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.

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.”

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.
