QUARTZ TUNING FORK The small QCL has only become available in recent years, Tittel says, and is far better able to detect trace amounts of gas than lasers used in the past.

What makes the technique possible is the small quartz tuning fork, which vibrates at a specific frequency

#A portable asbestos detector that could save thousands of lives. A European research project, ALERT, has developed an asbestos detection device that could save thousands of lives.

The project team is building the first real-time, portable detector of asbestos fibres in the air. The low-cost ALERT Rapid Asbestos Detection (ARAD) tool,

which will be the size of a hand-held drill, is expected to enable construction workers and surveyors to test for the mineral's presence in building and demolition sites.

ALERT project coordinator Alan Archer says the tool is expected to instantly give potentially lifesaving information about the levels of asbestos to people working on building and demolition sites

surveying premises, and even firefighters. e hope this instrument will prompt a major change in the way the world addresses the dangers of asbestos, with the ultimate goal of saving lives,

he states. Once embraced as the iracle mineralfor its tough, flexible, fireproof qualities, asbestos is seen now as a health hazard.

It causes lung diseases like the malignant form of cancer called mesothelioma. Yet asbestos is still with us.

Exposure from legacy asbestos products like insulation is the leading cause of work related deaths worldwide,

and until now there has been no way of detecting the lethal presence of asbestos fibres in the air.

The World Health Organisation (WHO) says 125 million people worldwide encounter white asbestos in the workplace

while the International labour organization (ILO) estimates that 100,000 workers worldwide die each year from all asbestos-related diseases.

ALERT project picks up research from the 1990s by the University of Hertfordshire, UK, which found a way to detect asbestos fibres through a new light scattering technique.

At the time, the project stalled as it was seen as too costly, but the ALERT consortium used recent technological innovations

and added them to existing research to build a low-cost, portable detector. ur challenge was to take this science

Archer says the project has potentially immense implications. here are no safe levels of asbestos exposure

often leaving those working in asbestos-laden buildings at risk of exposure. Archer is currently working with third parties to develop new prototypes capable of addressing specific market sectors such as demolition

emergency services, asbestos removal and hazardous waste sites. ith ALERT tool, we can give 30 million European workers a means of detecting asbestos the moment it is disturbed,

and avoid becoming one of the 100,000 people worldwide killed each year by exposure to asbestos,

#OXYMOD-Cleaner power thanks to mathematics Mathematical modelling has in recent years proven to be a useful and cost-cutting tool for designing and modernising coal fired power plants.

The Oxymod project supported by the European union (EU) Research Fund for Coal and Steel (RFCS) has striven to extend existing combustion modelling capabilities to oxy fuel combustion conditions.

Oxy fuel technology was proposed for conventional pulverised coal fired combustion already in the'80s; however, recent developments have led to a renewed interest in the technology, with the ultimate goal of significantly reducing CO2 EMISSIONS via capture.

An extensive database of oxy fuel and air combustion trials in gas-and coal fired testing facilities has been compiled.

SMARTFIRE was a 42 month Research Fund for Coal and Steel (RFCS) project that greatly enhanced reheating furnace operation,

In their experiments reported in the journal Science researchers measured the MRI signal with a novel diamond sensor chip using an optical readout in a fluorescence microscope.

The sensor consisted of an impurity in diamond known as the nitrogen-vacancy center. In this case two carbon atoms are missing in the otherwise regular diamond lattice

while one of them is replaced by a nitrogen atom. The nitrogen-vacancy center is both fluorescent and magnetic making it suitable for extremely precise magnetic field measurements.

For their experiment the researchers prepared an approximately 2×2 millimeter piece of diamond such that nitrogen-vacancy centers formed only a few nanometers below the surface.

Fusion power designs aren t cheap enough to outperform systems that use fossil fuels such as coal and natural gas.

The lab discovered boiling down a solution of graphene quantum dots (GQDS) and graphene oxide sheets (exfoliated from common graphite) yielded self-assembling nanoscale platelets that could then be treated with nitrogen and boron.

#New nanothreads are like diamond necklaces Scientists say super-thin iamond nanothreadsould be stronger and stiffer than the strongest nanotubes

The core of the nanothreads is a long thin strand of carbon atoms arranged just like the fundamental unit of a diamond s structure zigzag yclohexanerings of six carbon atoms bound together in

as if an incredible jeweler has strung together the smallest possible diamonds into a long miniature necklacebadding says. ecause this thread is diamond at heart we expect that it will prove to be extraordinarily stiff extraordinarily strong

and to link up in a highly ordered chain of single-file carbon tetrahedrons forming these diamond-core nanothreads. adding s team is the first to coax molecules containing carbon atoms to form the strong tetrahedron shape then link each tetrahedron end to end to form a long thin nanothread.

The resulting diamond-core nanothread is surrounded by a halo of hydrogen atoms. During the compression process the scientists report the flat benzene molecules stack together bend

The result is a structure that has carbon in the tetrahedral configuration of diamond with hydrogens hanging out to the side and each tetrahedron bonded with another to form a long thin nanothread. t really is surprising that this kind of organization happensbadding says. hat the atoms

so that when we release the pressure very slowly an orderly polymerization reaction happens that forms the diamond-core nanothread.

arts of these first diamond nanothreads appear to be somewhat less than perfect so improving their structure is a continuing goal of Badding s research program.

He also wants to discover how to make more of them. he high pressures that we used to make the first diamond nanothread material limit our production capacity to only a couple of cubic millimeters at a time so we are not yet making enough of it to be useful on an industrial scalebadding says. ne of our science goals is to remove that limitation by figuring out the chemistry

necessary to make these diamond nanothreads under more practical conditions. he nanothread also may be the first member of a new class of diamond-like nanomaterials based on a strong tetrahedral core. ur discovery that we can use the natural

alignment of the benzene molecules to guide the formation of this new diamond nanothread material is really interesting

#From coal, cheap quantum dots in one step Chemists have discovered how to reduce three kinds of coal into graphene quantum dots (GQDS) that could be used for medical imaging as well as sensing electronic and photovoltaic applications.

The new process described in the journal Nature Communications allows a measure of control over their size generally from 2 to 20 nanometers depending on the source of the coal.

That involved crushing the coal and bathing it in acid solutions to break the bonds that hold the tiny graphene domains together. ou can'##t just take a piece of graphene

GQDS were derived from bituminous coal anthracite and coke a byproduct of oil refining. The coals were each sonicated in nitric and sulfuric acids and heated for 24 hours.

Bituminous coal produced GQDS between 2 and 4 nanometers wide. Coke produced GQDS between 4 and 8 nanometers and anthracite made stacked structures from 18 to 40 nanometers with small round layers atop larger thinner layers.

Just to see what would happen the researchers treated graphite flakes with the same process

and got mostly smaller graphite flakes.)The dots are water-soluble and early tests have shown them to be nontoxic offering the promise that GQDS may serve as effective antioxidants Tour says.

Medical imaging could also benefit greatly as the dots show robust performance as fluorescent agents. ne of the problems with standard probes in fluorescent spectroscopy is that

when you load them into a cell and hit them with high-powered lasers you see them for a fraction of a second to upwards of a few seconds

Cheaper graphite is $800 a ton from China. And coal is $10 to $60 a ton. oal is the cheapest material you can get for producing GQDS

and we found we can get a 20 percent yield. So this discovery can really change the quantum dot industry.

The theoretical calculations pointed to new families of materials where this often mutually exclusive combination of properties could in fact be stabilized. his structure is something known as a perovskite crystal.

A perovskite crystal has the same cubic lattice of metal atoms but inside of each cube is an octahedron of oxygen atoms

It's not something we had to architect ourselves. fter several failed attempts to physically produce the specific perovskite crystals they had theorized the researchers succeeded with a combination of potassium niobate the parent polar material and barium nickel niobate

Similar sulfur-polyaniline composites have previously been synthesized in a ore-shellstructure but the new method provides an internal void within the polymer shell called a olk-shellstructure. hen the lithium-sulfur battery was discharged fully the volume of the sulfur expanded dramatically to 200 percent.

#rtificial nose detects dangerous vapors Researchers have developed a way to sniff out solvent gases by combining a common mineral zeolite with a metallic compound based on rhenium.

The challenge for Angel Mart assistant professor of chemistry and bioengineering at Rice university and his team of student researchers was to get their large metallic particles through the much smaller pores of a zeolite cage.

but when they self-assemble inside the zeolite they re trapped. Once washed to eliminate complexes that form outside the zeolites the compound is ready for use.

#Is this mineral to blame for deep earthquakes? University of Chicago rightoriginal Studyposted by Steve Koppes-Chicago on September 25 2013scientists are closer to understanding deep earthquakes which occur

-triggered brittle failures during the olivine-spinel (mineral) phase transformation has many similar features to deep earthquakes. ang

when a mineral common in the upper mantle olivine undergoes a transformation that weakens the whole rock temporarily causing it to fail. ur current goal is to understand why

or flow rather than by the kind of brittle fracturing we see at smaller depthsgreen explains. oreover at depths of more than 400 kilometers the mineral olivine is no longer stable

and undergoes a transformation resulting in spinel a mineral of higher density. he research team focused on the role that phase transformations of olivine might play in triggering deep earthquakes.

They performed laboratory deformation experiments on olivine at high pressure and found the arthquakesonly within a narrow temperature range that simulates conditions where the real earthquakes occur in Earth. sing synchrotron X-rays to aid our observations we found that fractures nucleate at the onset of the olivine to spinel transitiongreen says. urther these fractures propagate dynamically

so that intense acoustic emissions are generated. These phase transitions in olivine we argue in our research paper provide an attractive mechanism for how very deep earthquakes take place. ang says researchers next goal is to study the material silicate olivine which requires much higher pressures.

The Institut National des Sciences de l Univers and L Agence Nationale de la Recherche and the National Science Foundation funded the work.

Federal emissions regulations make retrofitting aging coal plants prohibitively expensive while pending rules means it s unlikely any new coal fired power stations will be built in the years ahead.

So the TVA directors voted to transform the utility into a power provider that will obtain a majority of its electricity from carbon-free sources.
