The physical basis of high-throughput atomically precise manufacturing

nanotechnologyAtomically precise manufacturing (APM) can be understood through physics, engineering design principles, proof-of-concept examples, computational modeling, and parallels with familiar technologies. APM is a prospective production technology based on guiding the motion of reactive molecules to build progressively larger components and systems. Bottom-up atomic precision can enable production with unprecedented scope (in terms of product materials, components, systems, and performance), while fundamental mechanical scaling laws can enable unprecedented productivity.

Definition of the term 'nanomaterial'

nanomaterial_definitionIn order to regulate nanomaterials and to determine mandatory product labelling a generally accepted agreement what the term 'nanomaterial' means has to be reached beforehand. The EU Parliament requires that a definition shallbe science-based and comprehensive. Furthermore, for regulatory measures in individual sectors, it shall be unambiguous, flexible, easy and practical to handle. During the past few years various institutions came up with suggestions for a definition, leading to a recommendation of the EU commission, which finally is being accepted into new and existing EU legislation. Some provisions in this proposal are controversial and the implementation into specific sectoral legislation constitutes a major challenge.

Nanotechnology in sports equipment: The game changer

sports_equipmentThe degree of competitiveness in sports has been remarkably impacted by nanotechnology like any other innovative idea in materials science. Within the niche of sport equipments, nanotechnology offers a number of advantages and immense potential to improve sporting equipments making athletes safer, comfortble and more agile than ever. Baseball bats, tennis and badminton racquets, hockey sticks, racing bicycles, golf balls/clubs, skis, fly-fishing rods, archery arrows, etc. are some of the sporting equipments, whose performance and durability are being improved with the help of nanotechnology. Nanomaterials such as carbon nanotubes, silica nanoparticles, nanoclays fullerenes, etc. are being incorporated into various sports equipment to improve the performance of athletes as well as equipments.

Nanotechnology tools for neuroscience and brain activity mapping

brainA comprehensive understanding of the brain remains an elusive, distant frontier. To arrive at a general theory of brain function would be an historic event, comparable to inferring quantum theory from huge sets of complex spectra and inferring evolutionary theory from vast biological field work. The proposed Brain Activity Map is a project that will tap the hive mind of experts to make headway in the understanding of the field. Engineers and nanotechnologists will be needed to help build ever smaller devices for measuring the activity of individual neurons and, later, to control how those neurons function. Recent developments in nanoscale analysis tools and in the design and synthesis of nanomaterials have generated optical, electrical, and chemical methods that can readily be adapted for use in neuroscience.

Nanotechnology in the pulp and paper industry

nanocelluloseDuring the past few decades, nanotechnology has had tremendous advances in several areas of research and development. Every week we are witnesses to hundreds of articles and scientific publications reporting new pathways for nanoparticle/nanofiber production, modification and use in modern and high-tech applications. In this respect, the pulp and paper industry has not been absent of this development, which has motivated massive research about nanocellulose. This wonderful material, which is synthesized naturally in wood, is composed of nanofibrils with widths usually less than 20 nm, high aspect ratio and remarkable strength.

Researchers discover a naturally occurring topological insulator

KawazuliteStrange new materials experimentally identified just a few years ago are now driving research in condensed-matter physics around the world. Tthese "strong 3-D topological insulators" - TIs for short - are seemingly mundane semiconductors with startling properties. Topological insulators offer unique opportunities to control electric currents and magnetism, and are promising materials for future spintronic applications or could provide access to novel, fascinating physical phenomena. While so far, only synthetic TIs had been experimentally identified, researchers in Germany report the discovery of a natural occurring topological insulator: the mineral Kawazulite.

Nanotechnology sensors for the detection of trace explosives

explosionTrace detection of explosives generally involves the collection of vapour or particulate samples and analyzing them using a sensitive sensor system. Various factors, such as wide variety of compounds that can be used as explosives, the vast number of deployment means and the lack of inexpensive sensors providing both high sensitivity and selectivity have made trace detection a very complex and costly task. High sensitivity and selectivity, along with the availability of low-cost sensors, is essential to combat explosives-based terrorism. Nanosensors have the potential to satisfy all the requirements for an effective platform for the trace detection of explosives.

Nanotechnology in the media

pressThe media play an important role in the formation of society's opinion by drawing attention to selected topics and bringing them closer to the public. This applies in particular to areas with which a large percentage of the population would otherwise have no direct points of contact, such as nanotechnology. A new study of selected print media in the German-speaking countries now reveals the general picture of nanotechnology in the media, what topics are given significant treatment, which actors are consulted, and explains that (at least as yet) there is no need for any concerns about risk-centred controversial reporting on this technology.
