Vibrational properties of black phosphorus edges unveiled by MackGraphe

2016-10-15T11:06:07+00:00July 20th, 2016|Categories: Press releases|Tags: , |

The international scientific journal Nature Communications, from the Nature Publishing Group, published, on July 14, an article gathering experimental and theoretical results about the vibrational properties of black phosphorus edges, a crystal consisting of a stack of two-dimensional layers of phosphorus atoms.

The study, conducted by Henrique Ribeiro, Dr. Christiano J. S. de Matos, Dr. Dario Bahamon, Prof. Thoroh de Souza, all from MackGraphe – the Graphene and Nanomaterials Research Center at the Mackenzie Presbyterian University – and by five other specialists from Universidade Estadual Paulista “Julio de Mesquita” (Unesp), Universidade Estadual de Campinas (Unicamp), Universidade Federal de Minas Gerais (UFMG) and the National Singapore University (NUS), unveils a previously unknown property of black phosphorus, which can ultimately contribute to the development of nanodevices with improved performance.

Since graphene was first isolated, back in 2004, researchers from all over the world have demonstrated its potential to electronic and optoelectronic applications. Part of the research has also focused on finding other atomically thin nanomaterials with similar or complementary properties. The latest crystal to join this high-tech group of materials is black phosphorus.

Discovered in 1914, the material is not found in nature and received relatively limited interest during the first century after its synthesis. However, interest has boomed since 2014, when it was demonstrated that black phosphorus can be mechanically exfoliated with an adhesive tape (the same method used to isolate graphene), leading to crystals with few-atom thicknesses.

Unlike graphene, a single layer of black phosphorus, which became known as phosphorene, exhibits a “puckered” structure

High Tech Manufacturing Breakthrough for Australia

2016-04-11T08:42:57+00:00April 11th, 2016|Categories: Press releases|Tags: |

PRESS RELEASE

Australia will become the first country in the world to use the new ‘super material’, graphene in the large scale manufacture of an industrial product, the CEO of Imagine Intelligent Materials Pty Limited, Chris Gilbey said today.

Graphene, whose discoverers were awarded the Nobel Prize for physics in 2010 is a one atom thick layer of carbon extracted from graphite. It is 100 times stronger than steel, is impervious to water and gases, can stretch like rubber and has extremely high electrical and thermal conductivity.
Mr Gilbey said that Sydney headquartered Imagine IM, the leading Australian developer of graphene applications for industry had entered into a licensing agreement with Australia’s largest geotextiles manufacturer, Geofabrics Australasia Pty Limited. He said that the insights gained from working with Geofabrics, which is headquartered in Melbourne was key to the development of the graphene manufacturing solution.

The ground-breaking agreement will see Geofabrics become the exclusive Australian  licensee of Imagine IM’s graphene coating technology for applications in geotextiles. Geofabrics will use the technology to offer Australian civil engineering companies
significantly improved capacity to locate and remedy leaks with applications in landfill and mining construction.
“Increased environmental regulations in Australia and around the world are driven by the need to address water safety and conservation and by the need for cost effective leak detection in the mining industry. We estimate our technology will save customers around 20 to 40 percent on their current solution costs,” Mr Gilbey said.
“Our graphene coating technology has the potential to become a key element of the world’s geotextiles industry which is growing at around ten percent per annum and will
