Using Sound To Levitate And Move Things In Three Dimensions

Posted by in categories: biotech/medical, health

ultrasonic 3D levitation
Japanese researchers have developed a way of not only levitating, but also moving objects three dimensionally using sound waves. The device uses four arrays of speakers to make soundwaves that intersect at a focal point that can be moved up, down, left, and right using external controls. And to human ears the device is completely quiet, as it uses ultrasound.

Occupational exposure to ultrasound in excess of 120 dB may lead to hearing loss. Exposure in excess of 155 dB may produce heating effects that are harmful to the human body, and it has been calculated that exposures above 180 dB may lead to death.[45] The UK’s independent Advisory Group on Non-ionising Radiation (AGNIR) produced a report in 2010, which was published by the UK Health Protection Agency (HPA). This report recommended an exposure limit for the general public to airborne ultrasound sound pressure levels (SPL) of 70 dB (at 20 kHz), and 100 dB (at 25 kHz and above).

Sensors Lead A New Age Of Man-Machine Collaboration

Posted by in categories: energy, health

“We shape our tools”, the old maxim goes, “and thereafter our tools shape us.” But what if both man and tools could shape and guide each other — as equals?

That’s the dream of the Senior Director of Advanced Technology at InvenSense, a TDK Group Company, Dr. Peter G. Hartwell, who believes we are heading into a profound new age of man-machine collaboration, led by breakthroughs in sensor technology. “Some problems simply can’t be solved using human senses or machine capabilities alone; we need a fusion of the two,” says Hartwell.

The problems which Hartwell targets are at the very core of a life well lived: customized health care, more energy-efficient infrastructure, productive workplaces, safer cities, and improved environmental monitoring.

Why the fuss about nurdles?

Posted by in categories: computing, transportation

Nurdles. The name sounds inoffensive, cuddly even… However, nurdles are anything but. “Nurdle” is the colloquial name for “pre-production plastic pellets” (which is in itself rather a mouthful); these are the raw material of the plastic industry – the building blocks for plastic bottles, plastic bags, drinking straws, car components, computer keyboards – in fact almost anything you can think of that’s made of plastic.

However, nurdles are also covering our beaches. I found that out for myself when Fauna & Flora International (FFI) first started researching this issue in 2009. Having read about them I went looking on my local beach, and was shocked to find so many nurdles in the strandline and trapped in washed-up seaweed. I had never noticed them before, but they had clearly been accumulating for some time.

While pictures of the tide of larger plastics in the ocean are front page news, the issue of nurdle pollution has received much less attention. Recent storms, however, have resulted in higher levels of nurdles being reported from a range of sites around UK coasts, highlighting the numbers of nurdles that are in our waterways, seas and sediments – a level of pollution which we can only see when they are flushed out and onto the beach. The Great Nurdle Hunt (an initiative of our partner Fidra) has mapped nurdle finds from around the UK and Europe, which has identified a number of nurdle hotspots in key industrial estuaries. However, this problem isn’t unique to Europe; nurdles are reported worldwide, but only hit the headlines when there are significant local spills from containers lost at sea, as recently occurred in South Africa. However, such one-off events aren’t the only source of nurdle pollution.

Robust and inexpensive catalysts for hydrogen production

Posted by in categories: energy, materials

Researchers from the Ruhr University Bochum (RUB) and the University of Warwick were able to observe the smallest details of hydrogen production with the synthetic mineral pentlandite. This makes it possible to develop strategies for the design of robust and cost-effective catalysts for hydrogen production. The working groups of Prof. Wolfgang Schuhmann and Dr. Ulf-Peter Apfel from the RUB and the team headed by Prof. Patrick R. Unwin from the University of Warwick published their results in the journal Angewandte Chemie.

Hydrogen gas is considered a possible future source of energy and can be produced from water using platinum catalysts and electricity. However, researchers seek alternative catalysts made of cheaper and more readily available with equally high efficiency. There are a number of materials that, like platinum, are able to catalyse the reaction of water into hydrogen. “These include metal chalcogenides such as the mineral pentlandite, which is just as efficient as platinum and is also significantly more stable toward poisons such as sulphur,” explains Ulf-Peter Apfel. Pentlandite consists of iron, nickel and sulphur. Its structure is similar to that of the catalytic centres of hydrogen-producing enzymes found in a variety of sources, including green algae.

In the current study, the researchers investigated rates of artificially prepared crystalline surfaces of the mineral pentlandite in a drop of liquid with a diameter of a few hundred nanometres. They used scanning electrochemical cell microscopy for this purpose.
