Before carbon nanotubes can fulfill their promise
as ultrastrong fibers, electrical wires in molecular devices, or
hydrogen storage components for fuel cells, better methods are needed
for purifying raw nanotube materials. Researchers have taken a step
toward this goal by demonstrating a simple method ...
Twisted Molecule
Large and folded like a protein - but completely synthetic.
Biofuel cells without the
bio cells - Pacific Northwest National Laboratory scientists
first to measure electrical charge shuttled by proteins removed from
living cells
"Zilch" instead of
explosion - Russian researchers know how to inhibit the
hydrogen-aerial mixture explosion or at least to reduce its power
significantly.
New Quantum Technology to
control molecules
A research team at the National Research Council Canada (Ottawa) has
developed a new quantum technology which uses laser pulses to control
quantum processes.
Researchers from the University of Chicago and
Argonne National Laboratory have deciphered the three-dimensional
structure of insulin-degrading enzyme, a promising target for new
drugs because it breaks down not only insulin but also the
amyloid-beta protein, which has been linked to the cognitive decline
of Alzheimer's disease.
Photochemistry
Creates Drug-Trapping Nanoparticles
A method that uses light to create a well-defined polymeric
nanoparticle with internal spaces that can provide a friendly
environment to water-insoluble drugs and channels through which the
entrapped drugs can escape into malignant cells.
Scientists at the Department of Energy's Lawrence
Berkeley National Laboratory have discovered that nanocrystals of
germanium embedded in silica glass don't melt until the temperature
rises almost 200 degrees Kelvin above the melting temperature of
germanium in bulk. What's even more surprising, these melted
nanocrystals have to be cooled more than 200 K below the bulk melting
point before they resolidify ...
Electromagnetic Miniatures
Simultaneous production of microchannels with parallel, electrically
conducting metal wires.
Images develop clinical
applications for new DESI technology
Researchers have created the first two-dimensional images of
biological samples using a new mass spectrometry technique that
furthers the technology's potential applications for the detection of
diseases such as cancer.
The Nobel
Prize in Chemistry 2006
The Nobel Prize in Chemistry for 2006 is awarded to Roger Kornberg. He
has studied how the genetic information stored in our genes is copied
so that the body can make use of it.
From
Bubbles to Capsules
Making silicon dioxide nanocapsules by frothing polymers with
supercritical carbon dioxide
Nanoscientists Create
Biological Switch from Spinach Molecule - Nanoscientists have
transformed a molecule of chlorophyll-a from spinach into a complex
biological switch that has possible future applications for green
energy, technology and medicine.
Opening a
Door into Cells
Research Shows How Ultrasound Can Deliver Therapeutic Molecules into
Living Cells.
Scientists at Carnegies Department of Plant
Biology have made the first real-time observations of sugars in the
cells of intact and living plant tissues. With the help of
groundbreaking imaging techniques, the group has determined that
plants maintain extremely low levels of sugar in their roots - as much
as 100,000 times lower than previous estimates. The new technology
will enable new studies of sugar metabolism in plants, which will
inform the effort to engineer higher crop yields for food and biofuel
production.
University of Arizona physicists have discovered
how to turn single molecules into working transistors. It's a
breakthrough needed to make the next-generation of remarkably tiny,
powerful computers that nanotechnologists dream of.
Polymers show promise for
lab-on-a-chip technology
Researchers are touting the use of liquid crystalline polymers (LCP)
as a viable tool for use in devices such as the sought-after
lab-on-a-chip technology.
Nanotube ink:
Desktop printing of carbon nanotube patterns
A better water test
A new method for detection and measurement of small amounts of water.
'Nanocantilevers' yield
surprises critical for designing new detectors
Researchers have made a discovery about the behavior of tiny
structures called nanocantilevers that could be crucial in designing a
new class of ultra-small sensors for detecting viruses, bacteria and
other pathogens
Filters in sunscreens that keep out ultraviolet
radiation can generate compounds that attack skin cells, say UCR
chemists.
When skin is exposed to sunlight, ultraviolet
radiation (UV) is absorbed by skin molecules that then can generate
harmful compounds, called reactive oxygen species or ROS, which are
highly reactive molecules that can cause "oxidative damage."
Scientists have found a way to
trick cancer cells into committing suicide. The novel technique
potentially offers an effective method of providing personalized
anti-cancer therapy.
Scientists at the Georgia Institute of Technology
have made an important step toward solving a critical puzzle relating
to a chemical reaction that leads to DNA mutation, which underlies
many forms of cancer.
Microcapsules Open in
Tumour Cells - Max Planck researchers channel microcapsules
into tumour cells and release their contents using a laser impulse.
Scientists from the research center
Forschungszentrum Rossendorf use the survival mechanism of special
bacteria to produce solid nanoclusters out of palladium. The tiny
bullets, only a few billions of millimeters in size, show new
properties, i.e. enhanced catalytic activity. Thus, bacteria-based
nanoclusters seem to be ideally suited for building new nano-catalysts.
Rehydrate - your RNA needs it.
Researchers have uncovered two previously unknown roles for water in
RNA enzymes, molecules which themselves play critical roles in living
cells and show promising medical applications.
