Scientists and engineers at BAE Systems have lifted the lid on some futuristic technologies that could be incorporated in military and civil aircraft of 2040 or even earlier. One of the four concepts is a nanotechnology that allows jets to quickly heal themselves from damage sustained in flight.
A recent study provides new insights on the physical mechanisms governing the interplay of spin and heat at the nanoscale, and addresses the fundamental limits of ultrafast spintronic devices for data storage and information processing.
The storage capacity of hard drives is increasing explosively, but the speed with which all that data can be written has reached its limits. Researchers present a promising new technology which potentially allows data to be stored 1,000 times as fast. The technology, in which ultra-short laser pulses generate a 'spin current', also opens the way to future optical computer chips.
A new discovery will make it possible to create pixels just a few hundred nanometres across that could pave the way for extremely high-resolution and low-energy thin, flexible displays for applications such as 'smart' glasses, synthetic retinas, and foldable screens.
This Timeline outlines important events related to nanotechnology policy and regulation in Canada, Australia, the European Union, the United Kingdom and the United States with an emphasis on developments since 2000.
Protons and neutrons are the basic constituents of atomic nuclei. Are they distributed homogeneously, or perhaps in quartets consisting of two protons and two neutrons? Physicists have recently presented an idea how this issue may be investigated in future experiments.
The first research program is aimed at so-called '7 nanometer and beyond' silicon technology that will address serious physical challenges that are threatening current semiconductor scaling techniques and will impede the ability to manufacture such chips. The second is focused on developing alternative technologies for post-silicon era chips using entirely different approaches, which IBM scientists and other experts say are required because of the physical limitations of silicon based semiconductors.
The method is able to drastically accelerate the development of materials that have a friction coefficient suited to the purpose of use, such as low-friction materials for reducing energy loss and high-friction materials required for high-performance brakes.
Researchers have developed a new methodology that can easily and precisely control the timing of and the structure as well as functions obtained in self-assembly of ?-conjugated molecules, which is a key technology in the field of organic electronics materials.
Researchers have caught a central step of photosynthesis in action for the first time. The team used the world's most powerful X-ray flashlight to record still frames of a molecular complex called photosystem II as it splits water into hydrogen and oxygen, a process that maintains the oxygen in earth's atmosphere.
Scientists explore the dynamics of correlated quantum systems. What does it mean for objects to interact locally versus globally? How do local and global interactions translate into larger, increasingly connected networks? How fast can certain entanglement patterns form?
Using high-brilliance X-rays, researchers track the process that fuel cells use to produce electricity, knowledge that will help make large-scale alternative energy power systems more practical and reliable.
