Photochromic properties of thienylpyrrole azo dyes in solution [PDF]
, 2006 The photochromic behaviour of thienylpyrrole azo dyes in THF solutions was studied for the first time. The photochromic properties are strongly dependent on the substitution pattern on the dyes.

Synthesis and Identification of Phenyl Azochalcone & bis- azo – Chalcone Derivatives Derived from P-amino Acetophenone [PDF]
Kirkuk Journal of Science, 2018 This work involves the synthesis of different substituted amino-chalcones via claisen- schmidt condensation reaction between p-amino acetophenone and different aromatic substituted benzaldehydes. The second step involves the conversion of amino-chalcones

Transparent Conductive Oxides-based Architectures for the Electrical Modulation of the Optical Response: A Spectroscopic Ellipsometry Study [PDF]
Journal of Vacuum Science & Technology B 37, 061209 (2019), 2021 Transparent Conductive Oxides (TCOs) are a class of materials that combine high optical transparency with high electrical conductivity. This property makes them uniquely appealing as transparent-conductive electrodes in solar cells and interesting for optoelectronics and infrared-plasmonics applications.

Nanoclay as Adsorbent: Evaluation for Removing Dyes Used in the Textile Industry [PDF]
, 2015 The dyes commonly used in the textile industry have structural resonant valence distribution, within a complex molecule, which determines the color of the dyes. The coloring is produced by chromospheres holding radiation in UV-visible range.

Photoinduced ordering and anchoring properties of azo-dye films [PDF]
Physical Review E 72, 061703 (2005), 2005 We study both theoretically and experimentally anchoring properties of photoaligning azo-dye films in contact with a nematic liquid crystal depending on photoinduced ordering of azo-dye molecules. In the mean field approximation, we found that the bare surface anchoring energy linearly depends on the azo-dye order parameter and the azimuthal anchoring ...

Oblique helicoidal state of the twist-bend nematic doped by chiral azo-compound [PDF]
arXiv, 2023 A novel light-sensitive chiral dopant ChD-3816 (an azo compound containing 4-hexanoyloxyphenyl and 2-isopropyl-5-methylcyclohexylbenzoate moieties) was used for inducing helical twisting in Ntb-forming mixtures of CB7CB/CB6OCB with 5CB added to decrease the phase transition temperatures.

Improved Performance and Reliability of p-i-n Perovskite Solar Cells via Doped Metal Oxides [PDF]
Advanced Energy Materials 2016, 1600285, 2016 Perovskite photovoltaics (PVs) have attracted attention because of their excellent power conversion efficiency (PCE). Critical issues related to large area PV performance, reliability and lifetime need to be addressed. Here, we show that doped metal oxides can provide ideal electron selectivity, improved reliability and stability for perovskite PVs. We

Effect of annealing on the structural, topographical and optical properties of sol gel derived ZnO and AZO thin films [PDF]
Materials Letters Volume 83, 15 September 2012, Pages 84-87, 2019 A comparative study of the physical properties of undoped Zinc Oxide (ZnO) and Al doped Zinc Oxide (AZO) thin films were performed as a function of annealing temperature. The structural properties were analyzed using X-ray diffraction and the recorded patterns indicated that the crystallinity of the films always enhanced with increasing annealing ...
