Nitrite standard solutions in 0.1 M phosphate buffer solution (pH 7.0) were measured using cyclic voltammetry with a potential range of 0.1 to 1 V and a scan rate of 100 mV s – 1 . The corncob biochar-modified carbon paste electrode provided better performance than the unmodified electrode, with an anodic peak of 20 mg L – 1 nitrite appearing at a potential of 0.84 V, indicating nitrite oxidation. In contrast, the unmodified carbon paste electrode did not show any significant peak. To confirm that the observed peak is indeed the anodic peak of nitrite, we conducted measurements at different nitrite concentrations of 0, 20, and 50 mg L – 1 . In the absence of nitrite, no significant peak was observed. However, in nitrite solutions, the anodic peak increased with higher concentrations of nitrite. Additionally, the corncob biochar-modified carbon paste electrode demonstrated good selectivity for nitrite detection, as cyclic voltammetric measurements of some interference components did not produce redox peaks in the potential range of nitrite oxidation. These findings suggest that corncob biochar has significant potential for the development of electrochemical nitrite sensors.","PeriodicalId":16654,"journal":{"name":"Journal of Nano-and electronic Physics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68045818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Physical reasons for the appearance of these differences, for linear systems of electromechanical piezoceramic transducers, are transients in electromechanical oscillatory systems of transducers and spatial spread of the systems. It is shown that the first reason is caused by the inertia of the transducers and the second – by the delay in the wave front when it propagates along the system.Typical dynamical changes in acoustic pulses, depending on the causes of their occurrence, were discovered. It is shown that the inertia of the mechanical oscillatory systems causes smooth increases and decreses, of the front and rear edges of acoustic pulses, respectively, in the directions of main and side lobes of the directivity of the system.It was discovered that typical dynamic changes in acoustic pulses caused by the delay in the front edge of the emitted wave, for the directions that are distant from the main and side lobes and interference zeros of the directivity, led to significant increase of their length, compared to electric ones and to the emergence of dips in the pulses’ amplitudes between their edges and their long sound after the end of the electrical stimulation of the systems’ transducers. Displayed dynamic changes in the emitted acoustic pulses compared to electrical stimulation pulses significantly worsen the parameters of location systems evaluated by the parameters of electrical impulses. Therefore, they must be considered when designing such systems.","PeriodicalId":16654,"journal":{"name":"Journal of Nano-and electronic Physics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68045991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FSO systems typically use lasers or light-emitting diodes (LEDs) as light sources to transmit data, and photodiodes or other light detectors to receive the data. In this paper, we investigate the error performance of a Free Space Optical system using various modulation techniques under different intensity fluctuation conditions. Our analysis takes into account the combined effects of atmospheric turbulence-induced fading and misa-lignment fading on the propagating signal. We derive novel closed-form expressions for the statistics of the random attenuation of the propagation channel for each modulation scheme used. Additionally, we perform a comparative study of bit-error rate (BER) performance for all modulation techniques considered in this work. We present numerical results to evaluate the error performance of all modulation schemes used in FSO systems with the presence of atmospheric turbulence and/or misalignment. Furthermore, we compare the OOK, PPM, DPSK, and BSPK modulation techniques to determine the best modulation that achieves the minimum BER for a given signal-to-noise ratio value equal to 30 dB in different scenarios.","PeriodicalId":16654,"journal":{"name":"Journal of Nano-and electronic Physics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68046296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The projections of the biological object were obtained by applying free space propagation of coherent radiation when no additional optical elements are placed between the sample and the detector equipped with a YAG:Ce scintillator to exploit the interference effects characteristic of the method due to the high-intensity characteristics of the X-ray light of the SOLEIL synchrotron. The energy of the X-ray photons was 10 keV, and the distance between the sample and the detector was 16.5 cm. We consider the use of standard Matlab tools for algorithmic correction of inhomogeneities of the detector and probing light beam used to build an image of the internal structure of the object and to evaluate the contrast of a group of images, by choosing such common quality criteria as PSNR and SSIM. The program is able to generate such a set of images depending on the parameters entered by the user for a subjective search for contrast images. Numerical estimates well confirm the visual results of the algorithmic search and allow us to reach the most informative image from the generated array, which is created by the user using the interface. The aim of this work is to familiarize with the use of the developed software product and the concept of semi-automatic search among the dataset of digital phase-contrast images.","PeriodicalId":16654,"journal":{"name":"Journal of Nano-and electronic Physics","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135698810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This design improves a number of microwave circuit features, including wide bandwidth, and achieved optimum gain, among others. The proposed antenna is intended to operate in the frequency range from 22 to 29.6 GHz, the antenna is mounted on a Rogers RT Duroid 5880 compact dielectric substrate with a thickness of 0.8 mm and a dielectric constant of ( ε r  2.2). Elliptical slots have been added in the simple capsule shape radiating patch to achieve wideband performance for the proposed antenna structure. The proposed antenna, with a frequency range from 22 to 29.6 GHz, has a wide bandwidth of 7.6 GHz. As a result, the proposed antenna design is small and appropriate for higher frequencies. The results of the simulation confirm that the antenna model is appropriate. In comparison to conventional patch, performance parameters like reflection coefficient, gain, and VSWR has improved. The EM simulator Ansoft HFSS v.15.0 performs all essential simulations, and a thorough comparative analysis based on the current antennas is performed. The suggested antenna has good impedance matching at |S 11 |  – 10 dB, VSWR is less than 2 and peak gain is 6.08 dBi at 24 GHz. Since the suggested antenna resonates at millimeter wave frequencies, it can be used for 5G applications. These excellent results in terms of tiny size, UWB operating band, high gain, good impedance matching, desired radiation features suggest that the proposed antenna would be a decent choice for 5G mm-wave applications.","PeriodicalId":16654,"journal":{"name":"Journal of Nano-and electronic Physics","volume":"258 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135698816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
