Физики и химики из Тартуского университета совместно с учеными из Эстонского центра по развитию нанотехнологий в ходе эксперимента, который вначале считался неудачным, открыли материал с совершенно новой структурой.

Неизвестный осадок, возникший в колбе в ходе обычного эксперимента, оказался потенциальным сырьем для производства крайне стойких материалов.

Materials scientists at the National Institute of Standards and Technology (NIST) have developed a process to build complex, three-dimensional nanoscale structures of magnetic materials such as nickel or nickel-iron alloys using techniques compatible with standard semiconductor manufacturing. The process, described in a recent paper,* could enable whole new classes of sensors and microelectromechanical ...

LIVERMORE, Calif. - Researchers have identified a signature for water inside single-walled carbon nanotubes, helping them understand how water is structured and how it moves within these tiny channels.This is the first time researchers were able to get a snapshot of the water inside the carbon nanotubes.Single-walled carbon nanotubes (SWCNTs) offer the potential to act as a unique nanofiltration system. ...

CHAMPAIGN, Ill. — Now you see it, soon you might not, researchers at the University of Illinois say.In computer simulations, the researchers have demonstrated an approximate cloaking effect created by concentric rings of silicon photonic crystals. The mathematical proof brings scientists a step closer to a practical solution for optical cloaking."This is much more than a theoretical exercise," said ...

AUSTIN, Texas–Mechanical engineering Assistant Professor Adela Ben-Yakar at The University of Texas at Austin has developed a laser "microscalpel" that destroys a single cell while leaving nearby cells intact, which could improve the precision of surgeries for cancer, epilepsy and other diseases."You can remove a cell with high precision in 3-D without damaging the cells above and below it," Ben-Yakar ...

LIVERMORE, Calif. - Lawrence Livermore National Laboratory researchers have captured time-series snapshots of a solid as it evolves on the ultra-fast timescale.Using femtosecond X-ray free electron laser (FEL) pulses, the team, led by Anton Barty, is able to observe condensed phase dynamics such as crack formation, phase separation, rapid fluctuations in the liquid state or in biologically relevant ...

A team of University of British Columbia researchers has developed a technique that controls the number of electrons on the surface of high-temperature superconductors, a procedure considered impossible for the past two decades.Led by Physics Assoc. Prof. Andrea Damascelli, the team deposited potassium atoms onto the surface of a piece of superconducting copper oxide. The approach allows the scientists ...

Applications of nanotechnology to electronics, photonics and renewable energy will be the focus of a joint forum to be held from August 10 to 14, 2009 at McMaster University in Hamilton, Ontario, Canada. An innovation workshop will also be presented in conjunction with the event.The 4th Nano and Giga Challenges Symposium and Summer School (NGC2009) and the 14th Canadian Semiconductor Technology Conference ...

The search for these natural but 'invisible' nanoparticles is important. If they can be proved to exist, the knowledge will help give us a deeper understanding of how gold can be transported and deposited by geological processes, and therefore help explorers to find new gold deposits in Australia.Now, hard evidence that gold nanoparticles have finally been seen in nature is presented in a paper published ...

WEST LAFAYETTE, Ind. - Researchers at Purdue University are developing a miniature refrigeration system small enough to fit inside laptops and personal computers, a cooling technology that would boost performance while shrinking the size of computers.Unlike conventional cooling systems, which use a fan to circulate air through finned devices called heat sinks attached to computer chips, miniature refrigeration ...
