Recent Graphene news:
Graphene might be better than silicon as substrate for polymer films, with many possible organic electronics application
Researchers at the Swedish Umea University revealed that semiconducting polymers, placed on a layer of graphene, transport electrical charges more efficiently than when the same polymer is placed on a silicon substrate.
The researchers say that graphene enhances the charge transport through the polymer film, making it potentially useful for producing more efficient electronic devices like organic solar cells, OLEDs and more.
Nokia, based in Finland and functions as a large multinational corporation, has recently published a job opening that raises the notion that it might move towards the prototyping phase of graphene-based sensors.
Nokia, which is known to be working on the R&D relating to optical sensors and has already patented a graphene-based photo detector in the past, published a job opening seeking "an expert in optoelectronics" that will be respnosible for developing graphene devices to create the basis for a range of optical sensor products. The ad also stresses the need for capabilities pertaining to fabrication of devices that are capable of volume production.
The Spanish company Graphenea, focused on the production of high quality graphene for industrial applications, is working with Spanish alliance of R&D centers IK4-Tekniker to jointly design automate graphene production precess.
Their objective is to design a more automated, standardisable, scalable and reliable production process, since the production of graphene sheets is often difficult and laborious.
It is well within the realm of gossip, but too interesting to pass on: rumor has it that a Chinese based international company called DJI is planning to come out with a drone called DJI Inspire Graphene around March-April 2015.
The multi-rotor aircraft is said to have graphene used in components like frame, arms and props to achieve light-weight and stiffness, but also in the drone's battery, for more capacity, faster loading and longevity. The battery part seems especially hard to believe as graphene batteries have not yet been commercially used.
Sheets of graphene and tungsten create innovative substance to potentially be used in solar panels and flexible electronics
Scientists at the University of Kansas managed to fabricate an innovative substance made of an atomic sheet of graphene interlocked with a sheet tungsten disulfide that could be used for solar cells and flexible electronics.
The material was formed using "layer to layer assembly" as a versatile bottom-up nanofabrication technique. The scientists then examined the motion of electrons between the layers through ultrafast laser spectroscopy, and found that nearly 100% of the electrons that absorbed energy from the laser pulse moved from the tungsten layer to the graphene within one picosecond, proving that the new material combines the properties of each component layer.
The U.S based public comapny Graphene 3D Lab, developer of graphene-enhanced materials for 3D printing, announced the signing of a memorandum of understanding with Taulman 3D, an American company that focuses on research and development of new 3D printing materials (with an accent on proprietary nylon materials), for the cooperation on research and development of 3D printing materials.
The agreement states that the companies will collaborate on the development of a graphene-infused nylon material for use in 3D printers, and Graphene 3D Lab will be granted exclusive distribution rights in North American for Taulman3D's Nylon 680 material, meant to start being sold in the beginning of 2015, for a two-year period.
Reseachers from University of Nebraska-Lincoln used graphene and ammonia to enhance the properties of a component that can be used in next generation RAM.
The scientists placed ammonia between graphene the ferroelectric layer to produce an enhanced ferroelectric tunnel junction that improved the reliability of RAM devices and allowed them to read data without the need to rewrite it.
