Self-assembly of silicon metamaterial for nanoscale reflectors

Recently highlighted in a C&EN article titled Simple Process Creates Near-Perfect Mirrors Out of a Metamaterial, researchers out of Vanderbilt University developed a method to self-assemble silicon nanostructures to achieve highly (Bragg-like) reflective mirrors which capitalize on nanoscale properties not present in bulk structures. The self-assembly method is far simpler than previous, conventional electron beam… Continue reading Self-assembly of silicon metamaterial for nanoscale reflectors

Computational nanotechnology reveals complex interactions in double-walled carbon nanotubes

Density functional theory calculations of the electronic properties of double-walled carbon nanotubes (DWCNTs) comprising two concentric zigzag tubes of different chiralities reveal complex effects upon the electronic band gap, identifying candidate combinations for diverse applications from transistors to macroscopic conducting wires.

Arrays of pure semiconducting carbon nanotubes for nanoelectronics

A very efficient and scalable method of completely removing metallic carbon nanotubes from mixtures of metallic and semiconducting carbon nanotubes produces arrays suitable for many applications and for studies of thin film transistors.

Conference video: Multi-Million Atom Simulations for Single Atom Transistor Structures

At the 2013 Conference Gerhard Klimeck presented the work of his computational nanotechnology network modeling nanoelectronic devices, using simulations of multi-million atom domains to understand the function of single atom devices embedded in larger nanostructures.

Nanoparticles shepherd DNA into cells to regulate immune response

DNA sequences designed to either stimulate a specific immune response or to down-regulate an undesirable response deliver superior performance when organized on nanoparticles to reach their intended cellular targets.

Nanowires and bacteria harnessed for artificial photosynthesis

A prototype system to produce chemicals and fuels from sequestered carbon dioxide, water, and sunlight uses semiconductor nanowires to produce electron-hole pairs, which are then used by two types of bacteria to produce oxygen and a variety of useful chemical products.

Science and technology roadmaps for nanotechnology

A European Science and Technology Roadmap for Graphene, Related Two-Dimensional Crystals, and Hybrid Systems hints at the opportunities to be harvested from, and the need for, the development of atomically precise manufacturing (APM).

Nanothreads formed from smallest possible diamonds

A new form of carbon produced by very slowly releasing benzene compressed at 200,000 times atmospheric pressure may be the strongest material possible.

UK SuperSTEM facility advances imaging and analysis of materials

Advanced aberration-corrected scanning transmission electron microscopes in UK facility provide atomically precise characterization of a variety of materials to guide R&D in alloys, drug delivery, lasers and other areas.

Gold nanotubes engineered for diagnosis and therapy

Gold nanotubes engineered to a specified length, modified surfaces, and to have other desirable characteristics showed expected abilities to enter tumor cells in laboratory studies, and to distribute to tissues within live mice as intended.
