Researchers describe a new method for designing geometric forms built from DNA. They present a novel variant on a technique known as DNA origami, in which the base-pairing properties of DNA are exploited for the construction of tiny structures in 2 and 3 dimensions.
The review is one part of the proceedings of a 2015 workshop organized by the PETA International Science Consortium, at which scientists discussed recommendations for designing an in vitro approach to assessing the toxicity of nanomaterials in the human lung.
This idea is part of the evolving science of precision agriculture, in which farmers use technology to target their use of water, fertilizer and other inputs. Precision farming makes agriculture more sustainable because it reduces waste.
Researchers aim to improve upconversion nanocrystals' composition and atomic structure to expand the library of bright and multicolor upconverters, while also generating fundamental understanding of light-matter interactions at the nanoscale.
A new rersearch report reveals a way to reduce the energy demand in one key step of the process for the polymerization of ethylene. It describes how a class of so-called Metal Organic Frameworks (MOFS) can effectively and selectively adsorb acetylene from the ethylene feedstock.
Scientists have developed a statistical method that obtains detailed descriptions of metal-molecule interfaces in single molecule junctions and verifies how molecular conformation can influence their performance. Their insights could help fine-tune the capabilities of nanoscale circuits.
Using atomic layer deposition, researchers deposited a thin film of nickel oxide onto a single crystal of titanium dioxide. Gold nanoparticles were introduced between the two layers to act like an antenna that harvests visible light.
