Graphene-based stress sensor could help NASA in testing anxiety levels of astronauts

A new graphene-based sensor that measures stress via cortisol in sweat could be used by NASA to gauge the anxiety levels of astronauts.

Developed by Caltech assistant professor of medical engineering, Wei Gao, the device features a plastic sheet etched with a laser to generate a 3D graphene structure with tiny pores in which sweat can collect. Those pores create a large amount of surface area in the sensor, which makes it sensitive enough to detect compounds in the sweat that are only present in very small amounts. Those tiny pores are also coupled with an antibody sensitive to cortisol, allowing the sensor to detect the compound.

UK-based rocket company Orbex develops graphene-enhanced rocket

Orbex, a UK-based private, low-cost orbital launch services company, has developed what it calls an "advanced, low carbon, high performance micro-launch" rocket called "Orbex Prime" and states that it already has a customer to fly on it.

Built with 3D-printed engines and a carbon fiber-and-graphene body, Orbex Prime will utilize renewable "bio-propane" as its fuel of choice. The two-stage rocket will be designed to carry up to 150 kilograms of payload, contained within a 1.3-meter fairing, into Sun Synchronous Orbit. Orbex even says its Prime rocket will be "80% reusable", although it is rather unclear how this would be executed.

New Graphene Flagship "Spearhead Projects" get €92 million in funding

The Graphene Flagship has announced the launch of eleven new "Spearhead Projects", each developed to take graphene-enabled prototypes to commercial applications. Now, the Graphene Flagship has committed €45 million to invest in eleven commercialization projects led by key industrial partners in Europe such as Airbus, Fiat-Chrysler Automobiles, Lufthansa Technik, Siemens, and ABB. Notably, the project partners will also co-fund the projects with a further combined contribution of €47 million, showing their interest in the development of graphene-enabled products.

The newly launched projects combine the results of the Graphene Flagship's innovative scientific research with the ambitions of commercial partners for marketable applications. This initiative will bring the number of companies involved in the Graphene Flagship to 78, which makes up nearly half of the whole consortium.

Graphene Flagship launches Airbus-Backed Project for graphene-based thermoelectric ice protection systems

The Graphene Flagship has announced the GICE Spearhead Project - development of a graphene-based thermoelectric ice protection system, that will aim to advance the technology readiness of graphene in such applications.

If ice accumulates on the wings, propellers or other surfaces of an aircraft, control can be dangerously inhibited. Thermoelectric ice protection systems prevent this from happening, using an ultra-thin conductive coating layer to generate heat when current is applied. The GICE project will attempt to use graphene to improve existing technology for this application.

2D Fab collaborates with SAAB and Blackwing to develop graphene-enhanced components for the aviation industry

2D fab, together with SAAB and Blackwing Sweden, developed new graphene-enhanced components for the aviation industry that offer increased lightning strike protection and strength.

The project, called Multigraph, was launched in 2017 with the mission to create better components for the aviation industry. The aim was to use graphene’s multifunctional properties to increase the mechanical strength and electrical conductivity of the materials used, the latter reducing the amount of maintenance required due to lightning strikes.

Haydale launches functionalized graphene prepreg for lightning strike protection

Haydale has launched a range of graphene-enhanced prepreg materials for lightning-strike protection, utilizing functionalized graphene to improve the electrical conductivity.

The material has been developed in collaboration with Airbus UK, BAE Systems, GE Aviation and Element Materials Technology Warwick, within the NATEP-supported GraCELs project where the first iterations of materials were developed and subjected to lighting strike tests. The consortium is now looking to manufacture a demonstrator component using the materials developed to establish composite manufacturing protocols as a showcase part for commercial purposes.

Graphene oxide proposed as significant component of interstellar dust

Peter J Sarre, Professor of Chemistry and Molecular Astrophysics at the University of Nottingham in the UK, has released a fascinating work that infers, based on previously unassigned optical and infrared astronomical observations and comparison with laboratory data on graphene oxide (GO), that GO is a significant component of interstellar dust.

Interstellar dust image

Dust particles play a major role in the formation, evolution and chemistry of interstellar clouds, stars, and planetary systems. Commonly identified forms include amorphous and crystalline carbon-rich particles and silicates. Also present in many astrophysical environments are polycyclic aromatic hydrocarbons (PAHs), detected through their infrared emission, and which are essentially small flakes of graphene.

Rice team designs graphene-based air filter that grabs and zaps pathogens

Rice University team under chemist James Tour has transformed their laser-induced graphene (LIG) into self-sterilizing filters that grab pathogens out of the air and kill them with small pulses of electricity. This may be of special interest to hospitals, where according to the Centers for Disease Control and Prevention, patients have a 1-in-31 chance of acquiring a potentially antibiotic-resistant infection during hospitalization.
