Colour-changing polymer adapts camouflage to vegetation and desert

Scientists are closer to producing outfits for the armed forces that change colour to match surroundings when soldiers move from a forest to a desert.

Clothing that adapts quickly to camouflage troops in different places would protect them against visual detection. Sunglasses, anti-glare mirrors and electronic display devices all use conducting polymers to change colour. Now, Wei Huang and Hong Meng at Nanjing Tech University, and their team in China, have designed an organic polymer that is green in the reduced state but oxidises and turns a sandy-brown when a low voltage is applied.

The full article can be read in Chemistry World.

Squid beak insight shifts chitosan composites up the pecking order

Inspired by squid beak, researchers in the US have created a lightweight composite from naturally abundant components that can be rigid at one end yet bendy at the other.

With a chitin beak and serrated chitin teeth on their arms and tentacles, nothing showcases biopolymer versatility quite like the giant squid. Unlike many strong biological materials, such as nacre in pearls or chiton mollusc teeth made of magnetite, chitin is devoid of metals and derives its extreme properties solely from organic molecules.

Interested? Read the full story in Chemistry World.

Journal of Materials Chemistry A, B and C – Hot Article Highlights

graphical abstractBidirectional acceleration of carrier separation spatially via N-CQDs/atomically-thin BiOI nanosheets nanojunctions for manipulating active species in a photocatalytic process
Jun Di, Jiexiang Xia,* Mengxia Ji, Li Xu, Sheng Yin, Zhigang Chen and Huaming Li*
J. Mater. Chem. A, 2016, Advance Article
DOI: 10.1039/C6TA00284F

Nitrogen-doped carbon quantum dots (N-CQDs) modified atomically-thin BiOI nanosheets nanojunctions have been controllably prepared. The obtained BiOI consisted of 1–2 [Bi–O–I] units, which is the thinnest BiOX material reported so far. The atomically-thin structure was designed to accelerate carrier transfer among the BiOI nanosheet interior while the N-CQDs were constructed to facilitate surface charge carrier separation. Bidirectional acceleration of carrier separation can be achieved via this unique structure for both the materials interior and the surface.

Bismuth doped materials with near infrared (NIR) photoluminescence (PL) have recently attracted tremendous attention because of their great potential for photonic and optoelectronic devices that could find broad applications in modern optical telecommunications. However, the mechanistic studies of the NIR PL from these materials still significantly lag behind, which imposes substantial limitations in rationally discovering and designing new materials. In this contribution, we investigated the optical and structural properties of Bi doped CsPbI3 using a diverse range of experimental techniques.

Conductive calligraphy

Wearable electronics have an array of potential uses from fashion to monitoring health, but washing them is far from straightforward. This prompted scientists in South Korea to return to a millennia old drawing board, where they discovered that calligraphy ink might solve the problem.
