Graphene Liquid Cells for Electron Microscopy Studies
A team of scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley has developed a technique for encapsulating liquids of nanocrystals between layers of graphene so that chemical reactions in the liquids can be imaged with an electron microscope. With this technique, movies can be made that provide unprecedented direct observations of physical, chemical and biological more
Transient Absorption: Label-free Imaging of Nanotubes in Cells
Researchers have demonstrated a new imaging tool for tracking structures called carbon nanotubes in living cells and the bloodstream, which could aid efforts to perfect their use in biomedical research and clinical medicine.more
Humbold University Berlin Uses AFM in the Study of Graphenes
The Physics of Macromolecules group of Prof. J.P. Rabe at the Humbold University in Berlin has recently shown the use of AFM in the study of the properties of graphenes. The research was published in Nano Letters 2011, 11 (6), pp 2436-2439. moreOct. 29, 2010How Graphene Nanotubes Interact
In awarding this year's Nobel Prize in Physics, the Nobel Prize Committee referred to graphene as a material with exceptional properties and huge potential for fabricating new materials and manufacturing innovative electronics. When a layer of graphene is rolled up to a seemless cylinder, a carbon nanotube is formed. The young investigators group of Dr Carola Meyer studied what happens if several of these tubes stick into each other. more
How Soccer Ball Molecules Push Their Way Under Surfaces
Fullerene and graphene, two forms of carbon only recently discovered, have been stimulating the imaginations of researchers ever since their discovery (fullerene in 1970, graphene in 2004). With graphene especially, researchers see a chance for a new chapter in electronics, since this semiconductor material could one day replace the long-standing key element silicon. For this to happen, it would have to be possible to dope graphene - which is a single-atom layer of graphite - with foreign atoms. And in such a way that the important structural properties of graphene remain intact. more
Single Carbon Atom Chains
80kV- High Resolution Transmission Electron Microscopy (HRTEM) characterization of micromechanically cleaved graphene shows in real- time atomically resolved dynamics of the carbon atoms in graphene constrictions. During electron irradiation, processes of hole formation generate graphene constrictions and eventually lead to stable single carbon atom chains. Carbon chains also occur between carbonaceous adsorbates and looping along graphene edges. more
Graphene Synthesis & Applications
Electron Microscopy Sciences (EMS) announced the addition of graphene transmission electron microscope support films to its product line. Graphene is a single atomic layer of carbon atoms tightly packed in a two-dimensional honeycomb lattice. The novel material has generated great interest throughout the scientific and technological community because of its remarkable properties and numerous potential applications. However, obtaining pure and highly ordered graphene has been a challenge. more- Legal
