Rough surface could keep small electronic parts from sticking together
When a piece of gift-wrapping tape sticks to itself, it's frustrating, but when small parts in a microgear or micromotor stick together, an electronic device may not work well, if at all. Scientists now report in the journal ACS Applied Materials & Interfaces that rough zinc oxide coatings can prevent tiny silicon parts from adhering to each other. The study could accelerate the development of even more advanced, high-performance electronics and small sensors.

Horizons of science in an e-book available for everyone
Science knows everything and is always ready with a clear answer to any problem -- this is what we think of science while leaving school and how the media present it. The real science is, however, different. What's like? The answer can be found in an e-book prepared by the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw.

New innovation could mean eye injections are a thing of the past
Drugs used to treat blindness-causing disorders could be successfully administered by eye drops rather than unpleasant and expensive eye injections, according to new research led by UCL scientists that could be a breakthrough for the millions worldwide suffering from age-related macular degeneration and other eye disorders.

Ultra sensitive detection of radio waves with lasers
Radio waves are used for many measurements and applications, for example, in communication with mobile phones, MRI scans, scientific experiments and cosmic observations. But 'noise' in the detector of the measuring instrument limits how sensitive and precise the measurements can be. Now researchers at the Niels Bohr Institute have developed a new method where they can avoid noise by means of laser light and can therefore achieve extreme precision of measurements.

A new renewable energy source?
Physicists at Harvard SEAS envision a device that would harvest energy from Earth's infrared emissions into outer space. Thanks to recent technological advances, the researchers say, Earth's warmth could soon be transformed into direct-current power, taking advantage of a vast and untapped energy source. Their analysis of the thermodynamics, practical concerns, and technological requirements will be published this week in PNAS.

Newly discovered catalyst could lead to the low-cost production of clean methanol
An international research team has discovered a potentially clean, low-cost way to convert carbon dioxide into methanol, a key ingredient in the production of plastics, adhesives and solvents, and a promising fuel for transportation. Scientists from Stanford, SLAC and the Technical University of Denmark combined theory and experimentation to identify a new nickel-gallium catalyst that converts hydrogen and carbon dioxide into methanol with fewer side-products than the conventional catalyst.

A molecular ballet under the X-ray laser
An international team of researchers has used the world's most powerful X-ray laser to take snapshots of free molecules. The research team headed by Professor Jochen Küpper of the Hamburg Center for Free-Electron Laser Science choreographed a kind of molecular ballet in the X-ray beam. With this work, the researchers have cleared important hurdles on the way to X-ray images of individual molecules, as they explain in the scientific journal Physical Review Letters.

Advantages emerge in using nanostructured material when forging mechanical components
In his Ph.D. thesis, the Industrial Engineer Daniel Salcedo-Perez has studied the process to forge mechanical components using nanostructured material. Specifically, he has been able to produce matrices to forge a set of mechanical parts like cogs and gears. 'These functional nanostructured components have been produced free of faults, and this is something that had not been done previously,' he pointed out.

More dangerous chemicals in everyday life: Now experts warn against nanosilver
Endocrine disruptors are not the only worrying chemicals that ordinary consumers are exposed to in everyday life. Also nanoparticles of silver, found in dietary supplements, cosmetics and food packaging, now worry scientists. A new study from the University of Southern Denmark shows that nano-silver can penetrate our cells and cause damage.
