Superconducting Chips To Become Reality PDF Print E-mail
Friday, 29 May 2009 10:39
Most chemical elements become superconducting at low temperatures or high pressures, but until now, copper, silver, gold, and the semiconductor germanium, for example, have all refused superconductivity. Scientists at the Forschungszentrum Dresden-Rossendorf (FZD) research center were now able to produce superconducting germanium for the first time. Furthermore, they could unravel a few of the mysteries which come along with superconducting semiconductors.
Long-sought Way to Make 'Nano-raspberries' May Fight Foggy Windows and Eyeglasses PDF Print E-mail
Tuesday, 26 May 2009 09:00
In an advance toward preventing car windshields and eyeglasses from fogging up, researchers in China are reporting development of a new way to make raspberry-shaped nanoparticles that can give glass a permanent antifogging coating. 
Scientists Create Custom 3-dimensional Structures with 'DNA Origami' PDF Print E-mail
Friday, 22 May 2009 09:49
By combining the art of origami with nanotechnology, Dana-Farber Cancer Institute researchers have folded sheets of DNA into multilayered objects with dimensions thousands of times smaller than the thickness of a human hair. These tiny structures could be forerunners of custom-made biomedical nanodevices such as "smart" delivery vehicles that would sneak drugs into patients' cells, where they would dump their cargo on a specific molecular target.
'Five Dimensional' Discs with a Storage Capacity 2,000 Times that of Current DVDs PDF Print E-mail
Friday, 22 May 2009 09:45
Futuristic discs with a storage capacity 2,000 times that of current DVDs could be just around the corner, thanks to new research from Swinburne University of Technology in Australia.
Aerosolized Nanoparticles Show Promise for Delivering Antibiotic Treatment PDF Print E-mail
Tuesday, 19 May 2009 15:03
Aerosol delivery of antibiotics via nanoparticles may provide a means to improve drug delivery and increase patient compliance, thus reducing the severity of individual illnesses, the spread of epidemics, and possibly even retarding antibiotic resistance.
Progress toward Artificial Tissue? PDF Print E-mail
Tuesday, 19 May 2009 13:40

For modern implants and the growth of artificial tissue and organs, it is important to generate materials with characteristics that closely emulate nature. However, the tissue in our bodies has a combination of traits that are very hard to recreate in synthetic materials: It is both soft and very tough.

Liquid Lens Creates Tiny Flexible Laser on a Chip PDF Print E-mail
Thursday, 14 May 2009 09:56
Like tiny Jedi knights, tunable fluidic micro lenses can focus and direct light at will to count cells, evaluate molecules or create on-chip optical tweezers, according to a team of Penn State engineers. They may also provide imaging in medical devices, eliminating the necessity and discomfort of moving the tip of a probe.
Chemists Discover Rare Rydberg Molecule with 'New' Type of Bonding PDF Print E-mail
Thursday, 14 May 2009 09:53
A rare “Rydberg” molecule discovered by scientists from the University of Stuttgart and University of Oklahoma has upheld scientific theory predicting the molecule existed. The team used a gas of rubidium atoms cooled to a temperature of 3 millionths of a degree above absolute zero to produce the molecule. The longest-lived molecule produced by the team survived only for 18 microseconds.
Silver Nanoparticles Show 'Immense Potential' In Prevention Of Blood Clots PDF Print E-mail
Tuesday, 02 June 2009 12:55
Scientists are reporting discovery of a potential new alternative to aspirin, ReoPro, and other anti-platelet agents used widely to prevent blood clots in coronary artery disease, heart attack and stroke. Their study involves particles of silver — 1/50,000th the diameter of a human hair — that are injected into the bloodstream.
New Rotors Could Help Develop Nanoscale Generators PDF Print E-mail
Friday, 29 May 2009 10:41
In collaboration with the Chinese Academy of Sciences in Beijing, scientists have investigated the rotation of molecules on a fixed surface to understand how they may help in the development of future rotor-based machinery at nanoscale level.
Buckyball Computer Simulations Help Team Find Molecular Key to Combating HIV PDF Print E-mail
Tuesday, 26 May 2009 09:02
Rice University's Andrew Barron and his group, working with labs in Italy, Germany and Greece, have identified specific molecules that could block the means by which HIV -- the deadly virus that causes AIDS -- spreads by taking away its ability to bind with other proteins.
New Memory Material May Hold Data for One Billion Years PDF Print E-mail
Tuesday, 26 May 2009 08:58
Packing more digital images, music, and other data onto silicon chips in USB drives and smart phones is like squeezing more strawberries into the same size supermarket carton. The denser you pack, the quicker it spoils. The 10 to 100 gigabits of data per square inch on today's memory cards has an estimated life expectancy of only 10 to 30 years. And the electronics industry needs much greater data densities for tomorrow's iPods, smart phones, and other devices.
Novel Approach Estimates Nanoparticles in Environment PDF Print E-mail
Friday, 22 May 2009 09:47
Without knowing how much of an industrial chemical is being produced, it is almost impossible for scientists to determine if it poses any threat to the environment or human health.
Non-wovens as Scaffolds for Artificial Tissue PDF Print E-mail
Thursday, 21 May 2009 15:24
When someone’s knee hurts with every step it’s a sign that the cartilage has been so badly damaged that the bones rub together when walking. Medical scientists are developing a technique to produce cartilage tissue artificially so that patients with such knee problems can walk free of pain again.
Single Electron Captured in Tunable Carbon Nanotube Quantum Dot PDF Print E-mail
Tuesday, 19 May 2009 13:42
Researchers from the Kavli Institute of NanoScience in Delft are the first to have successfully captured a single electron in a highly tunable carbon nanotube double quantum dot. This was made possible by a new approach for producing ultraclean nanotubes. Moreover, the team of researchers, under the leadership of Spinoza winner Leo Kouwenhoven, discovered a new sort of tunnelling as a result of which electrons can fly straight through obstacles.

New Method for Producing Transparent Conductors Developed PDF Print E-mail
Thursday, 14 May 2009 09:55
Researchers at UCLA have developed a new method for producing a hybrid graphene–carbon nanotube, or G-CNT, for potential use as a transparent conductor in solar cells and consumer electronic devices. These G-CNTs could provide a cheaper and much more flexible alternative to materials currently used in these and similar applications.
Chemists Develop New Preparation Process for Metal-organic Frameworks PDF Print E-mail
Tuesday, 12 May 2009 08:48
Many molecular materials, be they hydrogen for fuel cells or drugs, can be stored in metal-organic frameworks (MOFs). This would even be possible for metal nano particles for catalysis, were there not one little hindrance: if the void spaces in the MOF are too large, a second embedded framework system automatically develops during the synthesis process. This “uncontrolled proliferation” leads to a significant reduction in the size of the voids.
