Sensitive sensors could be made from spider silk fibre

Sensitive sensors could be made from spider silk fibre

Physicists have developed a way to help structurally modify spider silk fibre and microweld it with various metals and carbon-based materials1 — a method that could be useful for making various spider-silk-based microstructures such as ultrasensitive sensors. Spider silk is a tough and lightweight biomaterial. However, existing techniques that modify silk fibres using ultraviolet lightRead more about Sensitive sensors could be made from spider silk fibre[…]

Artificial leaf for harnessing sunlight

Artificial leaf for harnessing sunlight

Using a nanocomposite, researchers have made a thin-film device that can absorb sunlight like a natural leaf and split water, making it potentially useful for generating hydrogen fuel1. Producing hydrogen by harnessing the Sun’s power depends on various factors such as light-absorbing efficiency, charge separation and migration in a photocatalyst. It is difficult to makeRead more about Artificial leaf for harnessing sunlight[…]

Glowing quantum dots made from mango leaves

Glowing quantum dots made from mango leaves

By heating dried mango leaf extract, researchers have synthesized fluorescent graphene quantum dots that can be used for bioimaging and as intracellular temperature-sensing probes1. Existing fluorescent materials, such as organic dyes, metal clusters and quantum dots, are toxic to biological cells and unstable when exposed to light. In search of a biocompatible fluorescent material, scientistsRead more about Glowing quantum dots made from mango leaves[…]

Flame resistant green wood

Flame resistant green wood

By using multiwalled carbon nanotubes, starch and softwood, researchers have synthesized a green wood nanocomposite that is thermally stable and flame retardant, making it potentially useful for home and industrial applications1. Wood polymer composites made from petroleum-based polymers and solvents are not biodegradable and could pollute the environment. To prepare an ecofriendly wood nanocomposite, theRead more about Flame resistant green wood[…]
