How to reduce your home’s ecological footprint

We’re all kings and queens of our own castles.

Why satellites have those golden foils on them — and how it saves a lot of lives

Like many other NASA technologies, this also proved to be really useful on Earth.

Insulating nanowire cloth that traps heat perfectly could help tackle climate change

Researchers at Stanford University coated flexible textile fibers with metallic nanowires to form a cohesive network that acts as a fantastic thermal insulator. The flexible material, made of silver nanowires and carbon nanotubes, is knitted together so closely that the space between individual strands is smaller than the wavelength of infrared radiation. As such, the radiation emitted by our bodies bounces between the skin and cloth.

Organic topological insulator demonstrated for first time

Researchers at University of Utah have recently demonstrated that it is indeed feasible to construct a topological insulator from organic compounds. Topological insulators are deemed very important by scientists because of their unique property of conducting electrons on their edges, while at the same time acting as an insulator on the inside. These capabilities make it an ideal component for quantum

New polymer aerogels might become the wonder insulating material

Since they were first invented in 1931, aerogels have become widely used in the industry, mostly for insulation purposes, thanks to their low thermal conductivity and light weight. Traditional silica aerogels, however, are brittle and obtuse, typically unsuited for applications where flexing of the material would occur. A novel class of polymer aerogels seeks to fix most of these inconveniences, after scientists
