Researchers discovered that lithium-doped graphene sheets (3-60 layers in thickness) result in the highest ever sheet resistance and transmittance ever reported for continuous thin-films. This may prove to be an important step towards an ITO replacement for touch panels and solar cells.
The lithium was inserted between the graphene layers. As a result of this electrochemical intercalation, the Fermi level is upshifted by the doping effect, resulting in a more transparent and conductive material.
The Ningbo government in China decided to help build the local graphene industry as part of its strategic industry plans. The government will launch several graphene projects as part of its "medium and long-term plan for the technological innovation and industrial development of the graphene industry (2014 – 2023) in Ningbo" plan.
Ningo government will help support three stages of the graphene market - raw materials, graphene composite materials and equipment and final products.
Update: It turns out that Konstantin Novoselov did not join the new research institute, he just visited to give a lecture...
In 2013, Shanghai-based Powerbooster Technology developed a graphene-based flexible touch-panels for mobile devices, with ambitious plans to mass produce those panels. The graphene supplier for powerbooster is Bluestone Global Tech (BGT).
Now it is reported that BGT, Power Booster and Xiamen University established the Graphene Industrial Technology Research Institute in Xiamen. The will mainly develop the applications of graphene in batteries, touch screens, cancer treatment, LED lamps, sea water desalination and more.
Researchers from Monash University use graphene and carbon nanotubes to develop a spaser (a nano-laser that emits a beam of light through the vibration of free electrons unlike the electromagnetic wave-emission process of regular lasers).
This new spaser is more robust and flexible compared to regular spasers made from silver and quantum-dots. It can also withstand high temperatures and is eco-friendly.
Researchers from Rice University developed a method to create a hybrid graphene-nanotube material that promises to have a better electrical and mechanical qualities than both materials. They call this new material "rebar graphene" because it resembles the way a rebar is used in concrete.
The researchers say that the resulting material contains large, flexible and conductive transparent sheets of graphene that are much easier to manipulate than pure graphene. A few layers of this new material could prove to be a cost-effective ITO alternative for displays and solar cells.
Last month we reported that UK-based Perpetuus Carbon Technologies entered the graphene supply market and will soon start producing graphene materials (GNPs) in its new 100 annual-ton factory. Today Perpetuus launched two new graphene based products (developed in collaboration with Gwent Electronics Group).
The first is a graphene based ink that features a resistance below one ohm per square centimeter. Perpetuus says this is the most conductive graphene enabled ink in the world, and they are already able to immediately deliver single kilogram batches for R&D and manufacturing optimization. The company will be able to offer ton quantities later on. Perpetuus' inks are available in formulations for ink jet, flexographic printing and sensors technologies.
UK-based Perpetuus Carbon Technologies announced that it entered the graphene supply market. The company will soon start production of customer-tailored surface modified graphene materials (excellent quality stacked graphene flakes) in its new 100 annual ton facility. The company can provide 50Kb batches within 48 hours and ton-sized orders within 28 days. The price of their graphene materials is £50 ($83) per kilogram.
The company also holds an R&D arm (called Perpetuus Research and Development). The development activities focus on graphene based ink, and also include transparent condcutive films (for ITO replacement), stress strain actuators and printable coatable electrodes for use in lithium Ion batteries.
