Scientists have found a way to estimate uncertainties in computer calculations that are widely used to speed the search for new materials for industry, electronics, energy, drug design and a host of other applications.
Researchers have have found a way to change the magnetoresistance of a thin (100 nm) organic semiconducting material by pairing it with an even thinner layer - a self-assembled monolayer - to alter its characteristics. By demonstrating that this kind of fine tuning is both straightforward and repeatable, the researchers have opened up an unprecedented level of control over materials that hold huge promise for next-generation technologies.
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.
