Nanotechnology in the Olympic Winter Games

skiingModern sports equipment often appears to be a showcase for new material technologies and nowhere has this been more true than in global sport competitions. Some of the high-tech materials used by athletes in competitive winter sports are using nanomaterials. But, as the 2022 Beijing Winter Olympics has shown, other areas have benefited from nanotechnologies and nanoscience as well: ice skating, wearable monitoring devices, and even nanomaterial-based Braille printing of Olympic service manuals and spectator guides for vision impaired readers.

A new method to quantify structural helicity in chiral nanoparticles (w/video)

helixal-nanorodsResearchers have developed a novel technique to quantify the helical morphology of gold chiral nanorods. Such nanoparticles exhibit unique properties in a sense that they can change the circular polarization of light. In many cases, these properties are believed to be caused by the helical (or 'screw-like') morphology of the nanoparticles, but until now it was very difficult to objectively analyze their shape. This methodology is the first building block towards a fundamental understanding of the chiroptical activity of nanoparticles.

Novel nanomaterial-based light sails for low-power spacecraft propulsion in Earth orbit and interplanetary travel

light-sailAdapting the concept of interstellar laser sailing for Earth orbital maneuvering and solar system exploration, researchers propose that the fundamental advantages of laser propulsion are manifested at much smaller laser powers in applications where conventional electric and chemical rockets are traditionally utilized. This approach makes use of low-power lasers, which are available already today, and novel light sail nanomaterials. These lasers push small, cell phone sized probes to velocities and destinations that are beyond the reach of current technologies, such as ever bigger chemical rockets being built or state-of-the-art ion engines.

Technological improvements in lubricant development due to recent advances in nano additives

drops-on-leafThis article discusses the use of nanotechnology in lubricants. Nanoparticle additives show significant enhancements in lubricant attributes like anti-oxidation capability, tribological features, and thermal properties. Nanotechnology offers the possibility of using nanosized additives to increase the performance of lubricating oil. The addition of nanoparticles to conventional base oils is a promising method for improving properties like friction and wear resistance in instruments.

The future of learning: Cambridge Advance Online meets bionanotechnology

Cambridge_Advance_OnlineBeing a relatively young field, Bionanotechnology is often neglected within undergraduate and postgraduate curriculum. With an increasing number of researchers and professionals of different backgrounds coming into the field, there is a clear need to have learning platforms that cover techniques, strategies and methods that characterise the design of bionano structures. In September 2021, Cambridge Advance Online, a new educational initiative created between the University of Cambridge and Cambridge University Press and Assessment, launched a 6-week online course about Bionanotechnology: Bionanotechnology from Theory to Practice.

How nanotechnology can benefit smart cities

smart-citiesThe development of smart cities is linked to the development of new materials and devices, the use of sensor networks, the handling of huge amounts of data, the development of communication networks between objects, decision-making, and a range of other smart technologies. Many of these areas benefit from nanotechnology enabled materials and devices such as sensors, photovoltaics, efficient lighting systems or communication networks.

Sustainable polymer nanocoatings: An innovative concept

polymer-chainsThe modification of surface properties, such as metals, medical devices, and glass mirrors, represents a vital opportunity to inhibit the buildup of proteins or contaminants (i.e., fouling) for biomedical materials/devices, food packaging, many membrane filtration applications. Surface coatings with sustainable anti-fouling, bactericidal or the killing of bacterial membrane cells, and self-cleaning surface properties are particularly desirable and are receiving great attentions. Polymer-based coatings involving fabrications of nanostructured surfaces over conventional chemical-based antimicrobial agents have become major research efforts designed to greatly prevent protein/bacteria adsorption as well as to promote self-cleaning surface abilities for numerous industry applications.
