The journal club is intended to be a weekly natter about interesting recent research. We tend to stick to high-impact journals - Nature, Science, PNAS and PRL have been popular - but this is not prescriptive. Given the diversity of research in the CM group, chosen topics vary widely. Anyone and everyone is welcome: if you have a paper you want to discuss, email it to me (Joe Tavacoli
) and I'll slot you in.
Week beginning 25 January 2015

Personal Thermal Management by Metallic Nanowire-Coated Textile

Heating consumes large amount of energy and is a primary source of greenhouse gas emission. Although energy-efficient buildings are developing quickly based on improving insulation and design, a large portion of energy continues to be wasted on heating empty space and nonhuman objects. Here, we demonstrate a system of personal thermal management using metallic nanowire-embedded cloth that can reduce this waste. The metallic nanowires form a conductive network that not only is highly thermal insulating because it reflects human body infrared radiation but also allows Joule heating to complement the passive insulation. The breathability and durability of the original cloth is not sacrificed because of the nanowires' porous structure. This nanowire cloth can efficiently warm human bodies and save hundreds of watts per person as compared to traditional indoor heaters.
