The ability of corncob biochar as a modifier of carbon paste electrodes for nitrite sensing was investigated and compared to unmodified carbon paste electrodes. 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.
研究了玉米芯生物炭作为碳糊电极亚硝酸盐传感改性剂的性能，并与未改性的碳糊电极进行了比较。采用循环伏安法，在0.1 M磷酸盐缓冲溶液(pH 7.0)中测定亚硝酸盐标准溶液，电位范围为0.1 ~ 1 V，扫描速率为100 mV s - 1。玉米芯生物炭修饰的碳糊电极性能优于未修饰的电极，在0.84 V电位下出现20 mg L - 1亚硝酸盐的阳极峰，表明亚硝酸盐氧化。相比之下，未经修饰的碳糊电极没有出现明显的峰值。为了证实观察到的峰确实是亚硝酸盐的阳极峰，我们在不同的亚硝酸盐浓度(0、20和50 mg L - 1)下进行了测量。在没有亚硝酸盐的情况下，没有观察到明显的峰。然而，在亚硝酸盐溶液中，阳极峰随着亚硝酸盐浓度的增加而增加。此外，玉米芯生物炭修饰的碳膏电极对亚硝酸盐检测具有良好的选择性，因为某些干扰组分的循环伏安测量在亚硝酸盐氧化电位范围内不会产生氧化还原峰。这些发现表明，玉米芯生物炭具有开发电化学亚硝酸盐传感器的巨大潜力。

A significant difference between electrical impulses, used for stimulation of elements of the acoustic location systems, and acoustic pulses, emitted by the systems, that occurs in the systems during their operation, has been discovered experimentally. 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.

Free Space Optical (FSO) communication is a method of transmitting data using modulated light waves through free space, such as air or vacuum, instead of using traditional wired or fiber-optic cables. 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.

This paper describes a graphical user interface developed for the normalization of radiograms and semi-automatic search for the most contrast images using a given reference, the experimental data for which were obtained using the analytical technique of X-ray phase contrast imaging. 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.

In this paper, a simple and novel Ultra-wideband (UWB) micro strip patch antenna is developed with a compact dimension (15 12 0.8) mm 3 and low complexity. 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.
