“…12 The WO 3 /polyvinylimidazole core-shell structures have chemical and thermal stabilities higher than those of pure WO 3 nanoparticles. 13 Carbon coated CdS coreshell nanowires were reported by using a room-temperature chemical reduction method. 14 In addition, Bando et al published a series of articles on the core-shell morphologies for cable like 15a-f structures.…”

In this article, we report a simple, one-stage, efficient synthetic method for the growth of carbon sausages filled with in situ formed tungsten oxide nanorods (CSTON), without any external catalyst. The thermal dissociation of tungsten(VI) isopropoxide, 5% w/v in isopropanol at 700 1C in a closed Swagelok cell in an inert atmosphere yielded a CSTON product. The product is characterized by SEM, TEM, EDAX, C, H, N, S analysis, TGA, Raman spectroscopy, and HR-TEM. The assignment of the structure of the sausages as a carbon shell, with the central part being the WO x , is based on SAEDS spectra. The same reaction was also conducted at a lower temperature closer to the temperatures of solvothermal reactions, at 350 1C. The reaction yielded WO x nanorods with a diameter ranging from 10 nm to 50 nm and a length of up to 6 mm.

“…Electron rich species may neutralize the nucleophilicity of imine sites and resist hydrolysis. Yang et al 55 showed that covalently bonded composites of WO 3 and polyvinylimidazole exhibit better thermal and chemical stability as compared with non bonded composites. Core-shell structure 53,55 of the composites have proved to be specifically beneficial for electrochromic behaviour.…”

Electrochromic devices have emerged as new age technology devices due their low power consumption, eye friendly working modes, and simple structure with easily adjustable features. Such devices have vast application prospects in areas like energy efficient building architecture, flexible displays, next generation smart wearables, satellite thermal control, etc. Organic electrochromic material offers several advantages, including rich color, stretchable and flexible architecture, facile synthesis, and easy modification of optical properties. However there are certain technical issues, such as cyclic stability, durability, uniform color performance, etc, which are still to be resolved before large scale commercialization of organic electrochromic devices can occur. In recent years, various research teams have made efforts in developing new methods and technologies to overcome such issues. Here, we have summarized these innovative efforts taken in the last decade to help researchers analyze and compare different techniques adopted toward improving the performance of organic electrochromic devices.

“…Having been heated at 80°C for several hours, the H 2 WO 4 solution with citric acid was turned into a gel precursor. Next, high temperature treatment at 800°C in air made it finally possible to obtain light green tungsten trioxide nanoparticles [27]. The size of nanoparticles depended on the heating time of the H 2 WO 4 solution with citric acid at 80°C.…”
