Dotz Nano reveals proof of concept for a new type of flash memory

Posted by in categories: computing, quantum physics, solar power, sustainability

New Graphene based flash memory card coming.

Dotz Nano (ASX: DTZ) has successfully completed a proof of concept research study into the use of Graphene Quantum Dots (GQDs) in flash memory devices with the Kyung Hee University in South Korea.

GQDs are being developed for use in various applications including medical imaging, sensing, consumer electronics, energy storage, solar cells and computer storage.

Architects Reveal What They Think “The City of the Future” Will Look Like

Posted by in categories: space, sustainability

In Brief

  • From colonies on Mars to massive pods under the sea, architects and urban planners have come up with some wildly imaginative designs for the future of city living.
  • Given current population trends and our ever-worsening environment, we need to start thinking now about how humanity will live in the future.

When you imagine what the cities of the future will look like, it’s hard to think that we can do more than what some nations have already achieved. For instance, Dubai, Japan, and Singapore feature some of the world’s most impressive modern architectural marvels; Helsinki is pioneering a future in data transparency; Brazil is setting the standard for efficient and sustainable mass transportation and eco-consciousness; and Korea is defining an urban landscape anchored on digital connectivity.

But architects and urban planners are letting their imaginations run wild — after all, where else can we go but toward our most outlandish, exciting, and sometimes even dystopian imaginings of the future?

Full(erene) potential: Adding specific molecules to ‘trap’ charge carriers in semiconducting polymers

Posted by in categories: solar power, sustainability

In what could be called a classic “Eureka” moment, UC Santa Barbara materials researchers have discovered a simple yet effective method for mastering the electrical properties of polymer semiconductors. The elegant technique allows for the efficient design and manufacture of organic circuitry (the type found in flexible displays and solar cells, for instance) of varying complexity while using the same semiconductor material throughout.

“It’s a different strategy by which you can take a material and change its properties,” said Guillermo Bazan, a professor of chemistry and at UCSB. With the addition of fullerene or copper tetrabenzoporphyrin (CuBP) molecules in strategic places, the charge carriers in semiconducting materials—negative electrons and positive “holes”—may be controlled and inverted for better device performance as well as economical manufacture. The discovery is published in a pair of papers that appear in the journals Advanced Functional Materials and Advanced Electronic Materials.

In the realm of , device functionality depends on the movement of the appropriate charge carriers across the material. There have been many advances in the synthesis of high-mobility, high-performance materials, said lead author Michael Ford, graduate student in materials, but the fine control of the electrons and holes is what will allow these sophisticated polymers to reach their full potential.

Graphene cooking oil?

In Brief

  • Researchers have discovered a way to make soybean oil into the super-strong material graphene. The material has a wide variety of potential uses and can revolutionize electronics.
  • The material could be used to make cell phone batteries last 25 percent longer, make more effective solar cells, and even filter fuel out of air.

Researchers have found a way to turn cheap, everyday cooking oil into the wonder material graphene – a technique that could greatly reduce the cost of making the much-touted nanomaterial.

Quantum RAM: Modelling the big questions with the very small

Posted by in categories: climatology, computing, finance, quantum physics, singularity, sustainability

Nice write up. What is interesting is that most folks still have not fully understood the magnitude of quantum and how as well as why we will see it as the fundamental ingredient to all things and will be key in our efforts around singularity.

When it comes to studying transportation systems, stock markets and the weather, quantum mechanics is probably the last thing to come to mind. However, scientists at Australia’s Griffith University and Singapore’s Nanyang Technological University have just performed a ‘proof of principle’ experiment showing that when it comes to simulating such complex processes in the macroscopic world quantum mechanics can provide an unexpected advantage.

Griffith’s Professor Geoff Pryde, who led the project, says that such processes could be simulated using a “quantum hard drive”, much smaller than the required for conventional simulations.

Solar Power Has Officially Become the Cheapest Source for New Energy

Posted by in categories: finance, solar power, sustainability

When it comes to obtaining new energy, solar energy now costs less than fossil fuels, according to a report by the World Economic Forum (WEF). Data from Bloomberg New Energy Finance (BNEF) also show decreased prices, with the mean price of solar power in about 60 countries dropping to $1.65 million per megawatt, closely followed by wind at $1.66 million per megawatt.

Michael Drexler, Head of Long Term Investing, Infrastructure and Development at the World Economic Forum, found the downturn in prices to be an encouraging sign.

“Renewable energy has reached a tipping point—it now constitutes the best chance to reverse global warming. Solar and wind have just become very competitive, and costs continue to fall. It is not only a commercially viable option, but an outright compelling investment opportunity with long-term, stable, inflation-protected returns.”
