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.

Polymer nanocomposites - additives, properties, applications, environmental aspects

polymer-nanocompositeVarious additives are added to plastics to either improve processability, change product properties or protect them against thermal, UV or light influences. In the case of a polymer nanocomposite, the additives have at least one dimension of less than 100 nm and can be found in the form of platelets, fibres or particles. They primarily serve to improve tensile strength, thermoformability, flame retardancy, optical and electrical properties, and the barrier properties of the plastic into which they are incorporated.

What is the effect of temperature on a catalytic gold nanoparticle?

gold-nanoparticlesGold nanoparticles are of great importance for a wide range of industrial processes such as CO oxidation, water-gas shift reactions and oxygen reduction at the cathode of hydrogen fuel cells. Scientists investigated the three-dimensional atomic structure of gold nanoparticles at high temperatures. By combining two powerful techniques, electron tomography with atom counting, researchers tracked the morphology changes in gold nanoparticles when heated.

Textile electronics for virtual and augmented reality applications

virtual-realityVirtual reality (VR) and augmented reality (AR) are some of the hottest multidisciplinary technology trends right now, integrating computer, various sensor, graphic image, communication, measurement and control multimedia, artificial intelligence, and other technologies. Interactive electronic textiles will provide suitable platforms for VR/AR applications to provide a full range of sensory perceptions. Intrinsic conductive nanomaterials such as carbon nanotubes and metallic nanowires as well as nanoscale devices such as triboelectric nanogenerators are key to developing these electronic textiles.

Nanotechnology in fiction

nanobotThe ability to communicate new advances in science and technology has never been more important, and in that regard innovations with nanotechnology are growing more rapidly than ever with benefits to both society and the economy. However, for many consumers and the general public, the very idea of nanotechnology is both a wonder and an enigma. But how do we keep our society engaged with new nanotechnology at a time when everyone is more discerning? Well, one approach is to use storytelling.

Passive cooling of enclosed spaces

passive-coolingRadiative cooling is a passive cooling strategy for lowering the temperature of an object without consuming energy or emitting pollution. However, this cooling method becomes ineffective when heat accumulates continuously in an enclosed space, such as a stationary vehicle exposed to direct sunlight. Researchers propose a Janus thermal emitter that acts as a selective emitter on the top side and a broadband emitter on the bottom side. This design effectively draws heat from an inner space and the surface, because the bottom side can absorb thermal input in a broad spectral range, while the top side emits heat into space without disturbing ambient radiation.

Nanocoatings could prevent bird-strikes

birdstrikeTo birds, trees and sky reflected in glass appear to be habitat. They fly into windows at high speeds, and the loss of life is staggering. Unlike humans, most birds can see UV light. It therefore stands to reason that applying UV-reflecting coatings or patterns on windows and glass buildings can be particularly advantageous to prevent bird strikes. Tuning the UV reflectance properties of window glass (or any other surface for that matter) could result in higher UV reflectance that could be noticed by birds and potentially reduce bird-strike incidences, particularly in high-rise buildings and airplanes.
