Graphene Infrared Eye Needs No Signal Amplification


In the research described in the journal Nature Communications, scientists ... found that the combination of graphene and pyroelectric materialsÃÆâ€â„¢ÃƒÆ’ƒâہ¡ÃƒÆ’‚¢ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â€š¬Ã…¡Ãƒâ€šÃ‚¬ÃƒÆ’…¡Ãƒâہ¡ÃƒÆ’‚¬ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â‚¬Å¡Ã‚¬Ãƒâ€¦Ã‚¡ÃƒÆ’‚¬Ãƒâہ¡ÃƒÆ’‚ÂÂwhich generate a voltage when they are heated or cooledÃÆâ€â„¢ÃƒÆ’ƒâہ¡ÃƒÆ’‚¢ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â€š¬Ã…¡Ãƒâ€šÃ‚¬ÃƒÆ’…¡Ãƒâہ¡ÃƒÆ’‚¬ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â‚¬Å¡Ã‚¬Ãƒâ€¦Ã‚¡ÃƒÆ’‚¬Ãƒâہ¡ÃƒÆ’‚ÂÂyields a unique synergy that boosts the performance of thermal photodetectors.


The actual design of the device is fairly simple. The pyroelectric material acts as the substrate; a conductive channel made from single-layer graphene runs through it, and a floating gate electrode floats above it....

FGR's "Graphene Operations" update of 29 March didn't do much to excite the market. It hit the buzz words, but Company has still got a few boxes to tick (& down 9% today)

- feedstock ... is Sri Lankan vein graphite, which is being sourced from third party mines and very soon from the mine shafts being developed by the Company

- Sept 2016; commissioned its proto-type Graphene Cell with a nominal capacity to produce 5 tonnes p.a. of graphene

- Where customers are needing bulk supplies of graphene it is likely that a Cell can be installed on their factory floor under the supervision of FGR personnel

- FGR recognises the need to appoint serious and experienced marketing agents to accelerate the process of market penetration rather then rely on organic growth supervised by the FGR staff

- (and the humdinger) shareholders should be aware that the delays (?!) have had little or no impact upon the far more significant graphene commercialisation program.

Last month Sunshine Coast-based Nano-Nouvelle passed a new milestone in its quest to become a supplier to the battery industry ÃÆâ€â„¢ÃƒÆ’ƒâہ¡ÃƒÆ’‚¢ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â€š¬Ã…¡Ãƒâ€šÃ‚¬ÃƒÆ’…¡Ãƒâہ¡ÃƒÆ’‚¬ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â‚¬Å¡Ã‚¬Ãƒâ€¦Ã‚¡ÃƒÆ’‚¬Ãƒâ€Â¦ÃƒÆ’¢Ã¢Ã¢â‚¬Å¡Ã‚¬Ãƒâ€¦Ã¢â‚¬Å“ it successfully added a layer of graphite to its copper-coated polymer electrode component. Graphite adds energy storage to a battery's copper current collector and the success of the graphite coating trial means Nano-Nouvelle is ready to make "plug and play" anodes that can be dropped into existing battery manufacturing processes, chief executive Stephanie Moroz says.


"We are really pleased with this because we did have some concerns that have been raised by manufacturers and we have been able to answer them and come out with some good results," Ms Moroz told AFR Weekend.


Nano-Nouvelle is one of a growing band of Australian firms striving to improve on lithium-ion batteries or commercialise alternative technologies that are more durable, efficient and cleaner.

- Adelaide-based 1414 Degrees claims its molten silicon storage device can displace lithium at a tenth of the cost and is aiming for a $10 million mid-year IPO

- Melbourne-based Applied Nano Technologies is seeking $7.5 million to fund a commercial rollout of new hydrogen fuel cell technology,

- Brisbane-based Redflow has developed a household size zinc bromide flow battery.

- First Graphite Resources is commercialising "supercapacitor" storage technology that Tesla founder Elon Musk says is the next big breakthrough

- Relectrify, based in Richmond in inner Melbourne, is using technology to rejuvenate tired electric vehicle batteries and give them a second life in household storage.


Lithium-ion batteries have made great strides but need to pack more energy and become cheaper still to play a big role alongside other solutions such as demand management in stabilising the emerging decentralised, wind and solar power-dependent power grid.



This Lumafoil current collector could cut 10 per cent from the weight of lithium-ion batteries ÃÆâ€â„¢ÃƒÆ’ƒâہ¡ÃƒÆ’‚¢ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â€š¬Ã…¡Ãƒâ€šÃ‚¬ÃƒÆ’…¡Ãƒâہ¡ÃƒÆ’‚¬ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â‚¬Å¡Ã‚¬Ãƒâ€¦Ã‚¡ÃƒÆ’‚¬Ãƒâ€Â¦ÃƒÆ’¢Ã¢Ã¢â‚¬Å¡Ã‚¬Ãƒâ€¦Ã¢â‚¬Å“ the industry standard made by Tesla, Panasonic and LGChem ÃÆâ€â„¢ÃƒÆ’ƒâہ¡ÃƒÆ’‚¢ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â€š¬Ã…¡Ãƒâ€šÃ‚¬ÃƒÆ’…¡Ãƒâہ¡ÃƒÆ’‚¬ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â‚¬Å¡Ã‚¬Ãƒâ€¦Ã‚¡ÃƒÆ’‚¬Ãƒâ€Â¦ÃƒÆ’¢Ã¢Ã¢â‚¬Å¡Ã‚¬Ãƒâ€¦Ã¢â‚¬Å“ increasing the range of drones and electrical vehicles. Ms Moroz said Nano-Nouvelle was concentrating on the Lumafoil now because it was getting a lot of interest in it, and hoped to conduct field trials later this year and be in commercial production with battery manufacturers by the end of 2018.


In future, by substituting lithium metal or tin for graphite, it expects to be able to increase the capacity of lithium-ion batteries by 50 per cent ÃÆâ€â„¢ÃƒÆ’ƒâہ¡ÃƒÆ’‚¢ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â€š¬Ã…¡Ãƒâ€šÃ‚¬ÃƒÆ’…¡Ãƒâہ¡ÃƒÆ’‚¬ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â‚¬Å¡Ã‚¬Ãƒâ€¦Ã‚¡ÃƒÆ’‚¬Ãƒâ€Â¦ÃƒÆ’¢Ã¢Ã¢â‚¬Å¡Ã‚¬Ãƒâ€¦Ã¢â‚¬Å“ a huge boon for grid storage and households and businesses that want to run "off-grid" during blackouts. (pretty sure that should read "substituting graphite for Li or Sn" but there you go)

This New Graphene-Based Electrode Could Boost Solar Storage by 3,000%




The technology is flexible and can be attached directly to solar cells - which means we could finally be one step closer to smartphones and laptops that draw their power from the Sun, and never run out. .... a team from RMIT University in Melbourne, Australia decided to investigate how living organisms manage to cram a lot of energy into a small space, and their imagination was soon spurred on by the ingenious fractal-based leaves of a common North American plant ....


[for] an efficient way to store [energy] for later use without leakage over time. ...... engineers have been turning to supercapacitors - a type of technology that can charge extremely fast and release energy in large bursts. But for now, supercapacitors aren't able to store enough energy to make them viable as solar batteries. Using a fractal-based design in the graphene electrode and combining it with existing supercapacitors, [the] team achieved 30 times higher energy storage capacity.

FGR waiting on a "number of potential customers to complete their test work on samples which have been provided in recent months with the most likely applications being polymers in the first instance. It would be reasonable to expect sales order within the next few months, and certainly well before the end of the year."



...latest optimisation work has more than doubled the capacity of [a Graphene] Cell so that it can now produce up to 13 tonnes per annum with full utilisation, with the ability to produce at even higher rates demonstrated in some test runs, with as high as 300% improvement.


Each Cell now has the potential to generate sales in the order of $2m per annum as a result of these productivity improvements.


The number of operating cells will increase in line with the growth in demand for graphene. The actual manufacturing cost of the Cell as announced previously, was less than $50,000.

and .... still "actively seeking a graphene specialist with international exposure to strengthen its graphene production and marketing capabilities"
