GRAPHYNE - What is STRONGER than Graphene? - Explained in 3 min
What is stronger than Graphene? There are two carbon based materials, and today I will talk about Graphyne which is by far the strongest material that will ever be made by man for a while.
Graphyne is nothing but a combination of Graphene and Carbyne where the introduction of the chain with triple bond connections gives the extra strength.
Microbullet hits confirm graphene's strength at Rice University
Graphene's great strength appears to be determined by how well it stretches before it breaks, according to Rice University scientists who tested the material's properties by peppering it with microbullets.
The two-dimensional carbon honeycomb discovered a decade ago is thought to be much stronger than steel. But the Rice lab of materials scientist Edwin Ned Thomas didn't need even close to a pound of graphene to prove the material is on average 10 times better than steel at dissipating kinetic energy.

Simple test for Graphene
Here is a simple test to see if you have graphene on your hands. It's not the most definitive thing, but it really does get you in the ballpark.
Strength of strong materials: graphene, spider's silk and steel
A talk given by Harry Bhadeshia at the National University of Science and Technology (NUST-MISIS) in Moscow. Videos courtesy of Professor Alyona Ponomarenko.
Strength is a reflection of the ability of a material to support a load without undergoing permanent change, although ultimate strength refers to fracture. Spider's thread has a tensile strength of about 700 MPa but a density of only 1.3 grams per cubic centimetre, which apparently giving it a specific strength that is six times greater than steel of identical tensile strength. The silk is also claimed to be much tougher than steel. Graphene or carbon nanotubes with a strength of 130 GPa is said to be 100-300 times stronger than steel. When examining these and other claims in detail, it seems that the elementary science of strong materials has been forgotten. The purpose of this talk is to regurgitate the science and introduce methods of comparing materials that are justified.
New Discovery Could Unlock Graphene's Full Potential
It's time for an update on graphene, that super material of the future! Scientists have come up with some new ways of making it that are easier and cheaper than ever before.

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.

CARBYNE LAC Explained in 4 Min - Stronger than Graphene
CARBYNE LAC Explained - In this video we will talk about the two know or at least in theory, carbon structures that are by far stronger than Graphene.
In organic chemistry, a carbyne is a general term for any compound whose molecular structure includes an electrically neutral carbon atom with three non-bonded electrons, connected to another atom by a single bond. A carbyne thus has the general formula R-C3•
Its right name is Linear Acetylenic Carbon (LAC for short), and from wiki again, it’s an allotrope of carbon with chemical structure (−C≡C−)n where n is any number really. The key here is the triple bonds that make it really strong.

Graphene is a form of carbon that could bring us bulletproof armor and space elevators, improve medicine, and make the internet run faster — some day. For the past 15 years, consumers have been hearing about this wonder material and all the ways it could change everything. Is it really almost here, or is it another promise that is perpetually just one more breakthrough away?
