From recent references, this work gives informations on structural, morphological, electrical and optical properties as well as perfomance behaviour of the nanocomposite devies. The analyzed data have demonstrated that nanostructured composite materials consisting of conducting polymers (CP) and nanoparticles have significantly contributed to enhance both the performance parameters and working time of devices. The presence of inorganic nanoparticles in polymers has strongly influenced all physical properties of the polymers. In this work we concentrated to analyze the most interesting properties of the OLEDs, OSCs and OGSs, such as electro-luminescence, photo-electrical conversion, and gas sensing. This review work also shows in general, the discovery source of the CPs, some typical CPs and their composites used for the fabrication of nanocomposite devices which aim at different practical purposes.</p> Nguyen Nang Dinh Copyright (c) 2025 Communications in Physics https://vjs.ac.vn/cip/article/view/22081 Sat, 01 Mar 2025 00:00:00 +0700 Dispersion management in organic liquid-cladding photonic crystal fiber based on GeSe2–As2Se3–PbSe chalcogenide https://vjs.ac.vn/cip/article/view/22079 <p><em>We present a numerical study of the influence of the liquids on fiber properties. The PCF was proposed based on the GeSe<sub>2</sub>–As<sub>2</sub>Se<sub>3</sub>–PbSe chalcogenide, infiltrated with six organic liquids in air holes in the cladding. The guiding properties in terms of dispersion characteristics, mode area, nonlinear coefficient, and confinement loss of the fundamental mode were numerically investigated. The result is that it is possible to shift the wavelength of the zero dispersion by about 20 nm to longer wavelengths and to reduce the slope of the dispersion curve of the fiber by the liquid filling. The results obtained also show that the PCF has a larger mode area (lower nonlinear coefficient) when infiltrated with liquids with a higher refractive index. </em><em>At the same time, the presence of liquid in the cladding is responsible for the increase in confinement loss. In particular, the fiber has a lower confinement loss when infiltrated with liquids with a higher refractive index.</em></p> Van Hieu Le Copyright (c) 2025 Communications in Physics https://vjs.ac.vn/cip/article/view/22079 Tue, 01 Apr 2025 00:00:00 +0700 Impact of CHF Correlations on DNBR of the TRIGA Mark II Research Reactor under different operational modes and burn-up conditions https://vjs.ac.vn/cip/article/view/21959 <p>Departure from Nucleate Boiling Ratio (DNBR) is a crucial thermal hydraulics safety parameter for nuclear reactors. Hence selecting appropriate DNBR correlation is vital for design, licence and operation. The Bernath, Misrak, and Tong correlations have been utilized in PARET/ANL code in this study to calculate DNBR in TRIGA Mark II research reactor during both steady state and transient conditions, spanning from the beginning of cycle (BOC) to 1000 MWD of operation life. The findings reveal that the Bernath correlation consistently yields the lowest values across all operational phases compared to the Misrak and Tong correlations. Remarkably, the results obtained from the Bernath correlation align with the recommendations put forth by the General Atomics (GA) and Safety Analysis Report. Consequently, it is deemed suitable for application throughout all modes of reactor operation.</p> Md Altaf Hossen Copyright (c) 2025 Communications in Physics https://vjs.ac.vn/cip/article/view/21959 Fri, 07 Mar 2025 00:00:00 +0700
