Solar Cells Will be Made Obsolete

Rectenna Naval Optical 150928122542_1_540x360
A new kind of nanoscale rectenna (half antenna and half rectifier) can convert solar and infrared into electricity,
plus be tuned to nearly any other frequency as a detector.

Right now efficiency is only one percent, but professor Baratunde Cola and colleagues at the Georgia Institute of Technology (Georgia Tech, Atlanta) convincingly argue that they can achieve 40 percent broad spectrum efficiency (double that of silicon and more even than multi-junction gallium arsenide) at a one-tenth of the cost of conventional solar cells (and with an upper limit of 90 percent efficiency for single wavelength conversion).

Researchers have developed a new and highly efficient method for gene transfer. The technique, which involves culturing and transfecting cells with genetic material on an array of carbon nanotubes, appears to overcome the limitations of other gene editing technologies.

The device, which is described in a study published today in the journal Small, is the product of a collaboration between researchers at the University of Rochester Medical Center (URMC) and the Rochester Institute of Technology (RIT).

BUFFALO, N.Y. (WIVB) – The number of people being diagnosed with diabetes is growing. Every third American adult will develop type 2 diabetes within the next 35 years. But there may be a new way to manage the illness.

A new device might make managing your insulin levels or even treating allergies virtually painless. We know Western New York is becoming a hub for nano-medicine. Now a local organization is on the front lines of whats called nano- patch technology.

Nanoparticles can grow in cubic shape

Posted by in categories: energy, nanotechnology

The efficiency of many applications deriving from natural sciences depends dramatically on a finite-size property of nanoparticles, so-called surface-to-volume ratio. The larger the surface of nanoparticles for the same volume is achieved, the more efficiently nanoparticles can interact with the surrounding substance. However, thermodynamic equilibrium forces nanostructures to minimize open surface driven by energy minimization principle. This basic principle predicts that the only shape of nanoparticles can be spherical or close-to-spherical ones.

Nature, however, does not always follow the simple principles. An intensive collaboration between University of Helsinki, Finland, and Okinawa Institute of Science and Technology, Japan, showed that in some condition iron nanoparticles can grow in cubic shape. The scientists also succeeded in disclosing the mechanisms behind this.

“Now we have a recipe how to synthesize cubic shapes with high surface-to-volume ratio which opens the door for practical applications”, says Dr. Flyura Djurabekova from the University of Helsinki.

Researchers Found a Way to Shrink a Supercomputer to the Size of a Laptop

Posted by in categories: energy, nanotechnology, supercomputing

Scientists at the University of Lund in Sweden have found a way to use “biological motors” for parallel computing. The findings could mean vastly more powerful and energy efficient computers in a decade’s time.

Nanotechnologists at Lund University in Sweden have discovered a way to miniaturize the processing power that is found today only in the largest and most unwieldy of supercomputers. Their findings, which were published in the Proceedings of the National Academy of Sciences, point the way to a future when our laptops and other personal, handheld computing devices pack the computational heft of a Cray Titan or IBM Blue Gene/Q.

But the solution may be a little surprising.

Magic Microbes: The Navy’s Next Defense?

Posted by in categories: bioengineering, biotech/medical, computing, materials, nanotechnology, neuroscience, robotics/AI

Synthetic biology involves creating or re-engineering microbes or other organisms to perform specific tasks, like fighting obesity, monitoring chemical threats or creating biofuels. Essentially, biologists program single-celled organisms like bacteria and yeast much the same way one would program and control a robot.

But 10 years ago, it was extremely challenging to take a DNA sequence designed on a computer and turn it into a polymer that could implement its task in a specific host, say a mouse or human cell. Now, thanks to a multitude of innovations across computing, engineering, biology and other fields, researchers can type out any DNA sequence they want, email it to a synthesis company, and receive their completed DNA construct in a week. You can build entire chromosomes and entire genomes of bacteria in this way.
