Will your medical or bank records stored on CD or DVD still be retrievable 10 or 20 years from now? The answer depends on how well this type of media are cared for and on specific manufacturing processes used, according to a study* by researchers at the National Institute of Standards and Technology (NIST).
Knowing that CDs and DVDs will work reliably for a certain number of years is critical to government agencies, hospitals, banks and other organizations that store massive amounts of vital data on optical discs.
As part of a long-term project* with the Library of Congress (LOC), NIST researchers tested how well recordable optical disks made with different manufacturing processes held up when exposed to high temperatures, humidity and light levels. They found that some disks performed better than others and that excessive exposure to any of these conditions can accelerate the deterioration. Crucially however, they found that some disks can be expected to reliably store data for decades.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...
What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team of researchers has worked out the details of how...
For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
