Progress made in developing nanoscale electronics: New research directs charges through single molecules

molectronics

Scientists are facing a number of barriers as they try to develop circuits that are microscopic in size, including how to reliably control the current that flows through a circuit that is the width of a single molecule. Chemical engineers have now figured out how to reliably control the current that flows through a circuit that is the width of a single molecule.

Earlier work assumed that the liquid medium in which certain self-assembling particles float could be treated as a placid vacuum, but scientists have now shown that fluid dynamics play a crucial role in the kind and quality of the structures that can be made in this way.

Berkeley Researchers Create First Soluble 2D Supramolecular Organic Frameworks

2D Supramolecular Organic Frameworks

Berkeley Lab researchers have demonstrated the first soluble single-layer 2D honeycomb supramolecular organic framework that combines the ordering and porous features of metal-organic frameworks with the solubility of supramolecular polymers.

Scientists use DNA to shape graphene into the transistor of the future

graphene 2

Increasingly, quantum computers are predicted to be the next great leap in computational power — but in reality they are more likely to be the next next great leap. Right now we have to tailor experimental quantum chips to their particular mathematical process of interest, literally build them to solve a specific problem; today’s silicon solutions will reach the peak of their potential long before we can go buy Intel or AMD’s new plug-and-play quantum processor.

Engineers invent programming language to build synthetic DNA

1 uwengineersi

Similar to using Python or Java to write code for a computer, chemists soon could be able to use a structured set of instructions to “program” how DNA molecules interact in a test tube or cell.
A team led by the University of Washington has developed a programming language for chemistry that it hopes will streamline efforts to design a network that can guide the behavior of chemical-reaction mixtures in the same way that embedded electronic controllers guide cars, robots and other devices.

New nanotechnology breakthrough – “giant surfactants”

Giant Surficant Slide2

University of Akron researchers have developed new materials that function on a nanoscale, which could lead to the creation of lighter laptops, slimmer televisions and crisper smartphone visual displays.

Known as “giant surfactants” — or surface films and liquid solutions — the researchers, led by Stephen Z.D. Cheng, dean of UA’s College of Polymer Science and Polymer Engineering, used a technique known as nanopatterning to combine functioning molecular nanoparticles with polymers to build these novel materials.

3-D Self-Assembling Polymer and New Microchips

3-D Self-Assembling Polymer Materials Could Lead to New Microchips.

As computer chips continue to shrink, developers are reaching the limits on how small they can make patterns for wires. A team of researchers at MIT believe they have a solution to this problem. By using self-assembling polymer materials that form tiny wires and junctions, they found a new way of making complex three-dimensional structures.
