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 materials 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 polymer semiconductors, 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.

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 memory required for conventional simulations.

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.”

Most of us probably don’t think too much about the foodstuffs we buy in the supermarket. But behind the scenes, today’s food production system relies on a centralized, industrial-scale supply chain that’s still dependent upon soil-based agriculture for the majority of our food crops.

In many instances, that means that food has to travel long distances from farm to table, meaning that food has lost much of its freshness and nutritional value by the time it reaches your table. There’s also a growing awareness that this model isn’t sustainable: the pressures of increasing urbanization and loss of arable land, rising populations and the increased frequency of extreme weather events like droughts and floods — brought on by climate change — means that slowly but surely, we are going to have to change the way we grow our food.

The food retail, foodservice and industrial cooling industries are in the midst of a momentous transition in refrigeration system architectures. Regulations are driving the need to implement sustainable systems with options growing exponentially. Emerson’s natural refrigerant expert, Andre Patenaude, provides advice on the best alternatives to future proof your system.

To get to what many call the “end game” of achieving compliance and meeting corporate sustainability objectives, more businesses are looking at systems based on natural refrigerants to help them achieve these goals.

The term “natural refrigerant” refers to substances that naturally occur in the environment. Unlike the synthetic refrigerants that have commonly been used in refrigeration applications — including hydrofluorocarbons (HFCs) and chlorofluorocarbons (CFCs) — ammonia (NH3 or refrigerant name R-717), propane (refrigerant name R-290) and carbon dioxide (CO₂ or refrigerant name R-744) are three naturally occurring refrigerants that pose very little threat to the environment.

Who is responsible if a self-driving car crashes and causes property damages, physical harm or even death? Autonomous vehicle legislation is still very much in its infancy though it will certainly be an evolutionary process over the years. Corporations such as Tesla and Volvo have publicly stated that they will take responsibility for any faults in their software. However, Comma.ai’s CEO George Hotz (geohot) has stated that he is not responsible for any accidents caused by those who download his free self-driving vehicle software.

You’ve never seen a farm like this.
