Tungsten trioxide‐poly(3,4‐ethylenedioxythiophene) (WO3‐PEDOT) and tungsten trioxide‐polyfuran (WO3‐PFu) were prepared by rf rotating plasma polymerization. Electrochromic hybrid thin films were fabricated onto flexible polyethylene terephthalate (PET)/ indium tin oxide (ITO) film using electron beam evaporation method. In order to deeply characterize all films, scanning electron microscopy‐energy dispersive X‐ray spectroscopy (SEM‐EDS) and electrochemical impedance spectroscopy (EIS) techniques were used. The counter electrode effect on plasma modified WO3 nano hybrids‐based electrochromic devices (ECDs) was evaluated. By incorporating flexible vanadium pentoxide (V2O5) film as counter electrode, complementary ECDs were constructed through combining the hybrid flexible films (WO3‐PEDOT, WO3‐PFu) as working electrodes, which exhibit highly efficient electrochromic performance with low voltage operation. Especially, WO3‐PEDOT/V2O5‐based ECD owns a high optical modulation of 61.5 % at 750 nm driven by −1.0 V (coloration) and +1 V (bleaching) with fast response times (coloration time: 13.58 s, bleaching time: 8.07 s) and a high coloration efficiency of 527 cm2 C−1. This study can supply useful and efficient avenue for designing flexible complementary electrochromic device for energy‐saving flexible electronics.

“…The current research involving an inorganic compound nanomaterial as the strain gauge is a new adventure in meeting the latest trends. From the extensive literature survey, it was noticed that the exploration of the sensor application based on the V2O5 nanoparticles are limited [13], this work based on the development of pressure sensors offer a great deal of opportunity in exploring its potential.…”

A high yield of single phase orthorhombic vanadium oxide (V2O5) nanoparticles with solution combustion method is obtained in a very quick succession at 500 °C, by the utilization of Butea monosperma seed extract, to study its suitability towards pressure sensors. The Structural, Transmission spectral, Morphological, Compositional and the Absorption spectral analysis of the deposited vanadium oxide nanoparticle samples are examined using X-Ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM), High resolution transmission electron microscope (HRTEM), Energy dispersive X-Ray analysis (EDX) and Ultraviolet–visible spectroscopy (UV) respectively. The results from the structural analysis denote the nanoparticles with the crystallite size of 4.76 Å, dislocation density of 441.35*1016/m2 along with the micro strain of 76.0366*10-3. Infrared transmission spectral images clearly display three strong peaks at 1633.76 cm-1, 1070.80 cm-1 and 537.25 cm-1, stating the presence of a strong and stable vanadyl bonding structure. Images from its morphological analysis depict the nanoparticles are homogeneously porous without any cracks on its surface. The composition of the nanoparticles clearly displays the presence of vanadium and oxygen atoms in a strong bonding structure. Absorption spectral results showed that the obtained samples after synthesis are in nano size with narrow size distribution. The results obtained from the experimental analysis indicate a stable performance, good linearity and stability, indicating its suitability for pressure sensing application.

“…In contrast, the use of sacrificial soft biotemplates, i.e., deformable systems based on organic molecules or supramolecules, remains, as yet, a virtually unexplored area, with only a couple of recent works addressing this issue [20,21], despite the known ability of Ht to form nanocomposites with soft biopolymers [22]. There is no doubt, however, that this methodology will soon gain on importance, since soft biotemplating procedures proved fruitful in the syntheses of nanostructured metal oxides [23][24][25][26].…”

Synthesis of Nanocrystalline Mg-Al Hydrotalcites in the Presence of Starch—the Effect on Structure and Composition

et al. 2020

The study describes the synthesis of Mg-Al hydrotalcite (Ht) with the use of starch as a structure controlling biotemplate. Syntheses were carried out at room temperature, by co-precipitation at pH = 10. The investigated synthesis parameters included the nature of the precipitating agent (NaOH/Na2CO3 or NH3aq/(NH4)2CO3), the nature of starch (potato, corn and cassava), the method of starch addition to reagents, the method of drying and the effect of washing. The materials were examined with X-ray diffraction, scanning electron microscopy/energy dispersive X-ray spectroscopy and infrared spectroscopy. The data show that synthesis of Ht materials in the presence of starch, with use of the ammonia-based precipitant, enabled preparation of nanocrystalline Ht with very fine (<50 nm) particle size. All investigated starches had a similar effect on the crystallinity and the grain size of Ht precipitates. Ht with the smallest nanocrystals was obtained when starch was present in all solutions used for synthesis, and the final product subjected to freeze drying. Washing with water was found to enhance recrystallization and exchange of nitrates for carbonates. Infrared spectra showed that an interaction exists between the biopolymer template and the Ht particles, resulting in a higher degree of order within the Ht-adhering starch component.
