A very thin layer of pure carbon is called graphene and it is a single, firmly packed sheet of carbon atoms that are bound together in a lattice that is shaped in a hexagonal honeycomb form; in a scientific terminology, graphene is a carbon allotrope in a plane structure of sp2 bonded atoms, along with […]
Even if graphene production is still limited due to it being extremely expensive, there are still no signs of slowing down when it comes to experimenting and researching about this interesting material; in addition to this, various research laboratories that are located all over the world are continuously finding new processes and ways on how to gain more information about it, such as a more in-depth knowledge about graphene structure, how can graphene technology be utilized in more applications, and a whole lot more.
Experts have carried on with their research to be able to find then develop advanced uses for graphene in the year 2015; it definitely seemed like fresh scientific advances emerged everyday and in the new year of 2016, there are even more graphene news and findings featured in the headlines. Even if there is a high possibility that new applications and functions for graphene will be introduced to the public, it is still not guaranteed that 2016 will be the year where graphene will able to reach the mainstream.
One of the most recent graphene news to date is the accurate and fast sequencing via graphene nanopore;the fresh new concept that has been developed by the NIST or National Institute of Standards and Technology have created this for an accurate and rapid gene sequencing. This works by pulling a molecule of the DNA through a miniature and chemically triggered hole in graphene – an extremely thin sheet made out of carbon atoms – then detecting the change and development in the electrical current. The new proposal from NIST is to develop a brief chemical bond that relies on the capabilities of graphene to alter mechanical strains from destroying the bonds into blimps that can be measured in electrical currents.
The study of those at the NIST focused on how the strain influences the electronic properties of graphene and discovered that temporary changes that occurred in electrical currents indicate that a certain target base had just passed. To detect all of the present target bases, graphene ribbons (four all-in-all) – each one of them having different bases introduced into the pore – can possibly be vertically stacked to create an integrated DNA sensor.
Anothercurrentgraphene news has been announced by the Rice University where they shared about the alteration of graphene oxide ‘paper’ along strain. The similar slip and stick system that commonly leads to earthquakes are being worked on at a molecular level where it ascertains the nanoscale materials’ plasticity;plasticity is the presence of a specific material that will stay permanently deformed once strained. A few researchers who have numerous and different ideas such as pliable electronics, have decided to look into graphene oxide paper and how it can handle shear strain where sheets are pulled on at the ends.
Based on thecomputer models and experiments done at the Rice University, layers of graphene oxide get evenly disfigured just by an amiable amount of strain; they have also discovered that such mechanical properties alter depending on the levels of strain given. The tested graphene oxide paper was a pile of sheets on top of each other which resembled pancakes, and the molecules of oxygen functionalized the surface by increasing the roughness to these atom-thick sheets.
Each day, the potential of graphene batteries continue to develop and grow more apparent because of the numerous headlines and graphene news that boasts about new battery materials and graphene electrodes. Graphene, which is a sheet of extremely thin atom-bound layers that form together in a lattice patterned like a honeycomb, is widely known as […]
Graphene is a translucent carbon allotrope that has 2D properties; the carbon atoms present in this material are thickly packed in acommon atomic scale that displays a strong hexagonal design. Graphene’s hexagonal lattice form can be considered as a double triangular interleaving lattice which has been successfully used for computing the band structure for one […]
