The fifth generation (5G) of telecommunication is a promising technology that is yet to become globalized for the effective and fastest mode of communication. This wireless communications system has an extended entail for different Multiple Input Multiple Output (MIMO) antenna systems, focusing on low and high, and less gain, also at millimeter frequency. The frequency ranges have more capability varying from 28 GHz to 150 GHz with the easiest generation of 5G for higher data rates. A mono-element antenna working over the two different 5G mm-Wave frequency bands [n257 (28 GHz) and n260 (38 GHz) bands] is proposed to obtain. The prototype is built upon Duroid-5880 substrate having a permittivity of 2.3 and Loss tangent value of 0.00092. The prototype resonates at 28 GHz and 38GHz of the spectrum to yield better return loss than conventional. The proposed antenna-Inverted Matchstick Slotted Rectangular Patch (IMSRP) is implemented to be 9.84 dBi at 28 GHz band and 1.1195 dBi at 38 GHz by dual band for 5G. The overall designed parameters of the antenna are 16.5 20 0.508 mm, also does not have any defective in the ground portion made to resonate for dual bands of millimeter wave frequency band of 5G communication.

Titania nanoparticles have several industrial applications, including cosmetics, optical, photonic, and electrical devices. However, industrial production of these particles is difficult, complicated, and dependent on a variety of physical characteristics such as temperature and infrastructure availability. This research describes an instant industrial method for producing titania nanoparticles using a wet chemical sol-gel synthesis. X-ray diffractogram (XRD) and Fourier transform infrared spectroscopy (FTIR) analysis of as-synthesized titania nanoparticles revealed a strong diffraction peak at Bragg angle 25 , which can be attributed to the titania anatase phase, and vibration bonds at 463 cm – 1 , which confirms the presence of titania. The morphology of these titania nanoparticles was examined using a field emission scanning electron microscope (FESEM), which determined the particle size to be around 37 nm. Using diffuse reflectance spectroscopy (DRS), the optical properties of the as-synthesized nanoparticles were studied, and their band gap was determined to be 3.37 eV. At room temperature, the dielectric constant and loss of titania nanoparticles were measured as a function of frequency. Additionally, titania particles were mixed into transformer oil to assess its dielectric breakdown strength for better insulating properties.
二氧化钛纳米粒子有许多工业应用，包括化妆品、光学、光子和电子设备。然而，这些颗粒的工业生产是困难的，复杂的，并且依赖于各种物理特性，如温度和基础设施的可用性。本研究描述了一种使用湿化学溶胶-凝胶合成法生产二氧化钛纳米颗粒的即时工业方法。通过x射线衍射(XRD)和傅里叶变换红外光谱(FTIR)对合成的二氧化钛纳米粒子进行分析，发现在Bragg角25阶处有很强的衍射峰，这可以归因于锐钛矿相，并且在463 cm - 1处有振动键，证实了二氧化钛的存在。利用场发射扫描电子显微镜(FESEM)检测了这些二氧化钛纳米颗粒的形貌，确定了颗粒尺寸约为37 nm。利用漫反射光谱(DRS)研究了合成的纳米粒子的光学性质，确定了其带隙为3.37 eV。在室温下，测量了纳米二氧化钛的介电常数和损耗随频率的变化。此外，将二氧化钛颗粒混合到变压器油中，以评估其介电击穿强度，以获得更好的绝缘性能。

In 5G applications, the antenna system plays a vital role to maintain the efficiency of the signal coverage during transmission. The millimeter-wave (mm-wave) and sub-6 GHz bands are integrated into the new antenna system which is suggested for the 5G handheld devices. The suggested antenna is a single antenna system that covers a 32.4 GHz bandwidth from 5.8 GHz to 38.2 GHz. The intended antenna structure has been obtained by introducing T-Shaped slots in the patch along with presence of parasitic elements on either side. The antenna's FR-4 substrate is developed with dimensions of 30 28 1.6 mm 2 . The gain varies be-tween 5 and 32 dBi across the operating frequency. The parasitic components are designed and connected with the patch to support the patch's ability to radiate with multiple resonances over a wide operating band. The optimal antenna includes six resonant frequencies 11 GHz, 18.2 GHz, 20.3 GHz, 21.7 GHz, 23.2 GHz, and 27 GHz. During the entire working frequency, the Voltage Standing Wave Ratio (VSWR) is obtained below 2, which signifies well impedance matching. The antenna maintains an efficiency of at least 65 % throughout, making it a strong candidate for 5G devices. The novel antenna geometry with compact size, wide operating band with multiple fruitful resonant frequencies, high gain, good radiation efficiency, omni-directional stable radiation patterns are the major findings reported in this article.

The demand for concrete in the construction sector is growing gradually due to its strength and durability. Concrete's interior relative humidity influences its strength and longevity. In the process of internal curing concrete along with the surface moisture, extra internal moisture is provided so that self-desiccation or dehydration can be avoided. In this paper, biomaterial extract is used to examine the performance of internally cured concrete and is compared with the performance of air-cured and conventionally cured concrete. The dosages of biomaterial extract used as internal curing agents are 0.0 %, 0.20 %, 0.40 %, 0.60 %, 0.80 %, and 1.0 % by weight of cement. This manuscript focuses on the compressive power of M-20 grade concrete and using Biomaterial extract as an internal curing agent determined for 3, 7, and 28 days and compared with air-cured and traditional cured cement concrete respectively. From the experimental test results and observations, the compressive potency of M-20 grade tangible enhances with a boost in dosages of extract of biomaterial up to 0.60% by weight of cement, if the dosage increased more than 0.60 % compressive strength decreases. The results are optimistic in bio-self-cured concrete which is environmentally friendly and low-cost and also improves the level of hydration.

Analytical relations describing the electric fields of a radio-electronic element made in the form of a piezoceramic cylindrical shell with an internal acoustic screen and an elastic medium in the cavity between them are obtained by the method of coupled fields in multiply connected regions. A comparative analysis of the results of a numerical experiment carried out according to the frequency characteristics of the electric current of the element excitation, depending on the parameters of the design of constituents of the element, made it possible to establish a number of subtle effects in the formation of fields that are important for matching the element with the electronic generator that excites it. Possible ways to control the dynamic properties of the electric field of the transducer are determined for different compositions of the piezoceramic material of its shell and different distances between the screen and the shell. The ways of controlling the properties of the electric field of the transducer are determined, which include changes in the composition of the piezoceramic material of its shell, the dimensions of the inner screen and the distance between the screen and the shell. The results obtained make it possible to support the requirements for generator devices to ensure the energy efficiency of the corresponding radiating paths.

The characteristics of an overvoltage high-voltage nanosecond discharge in air at atmospheric pressure between polycrystalline electrodes made of a superionic conductor, silver sulfide (Ag 2 S), are given. In the process of microexplosions of inhomogeneities on the working surfaces of the electrodes in a strong electric field, vapors of the Ag 2 S compound and its dissociation products in the plasma are introduced into the interelectrode space due to the formation of ectons. This creates prerequisites for the synthesis of thin films from this material, which have the properties of superionic conductors and photovoltaic compounds and can be deposited on a dielectric substrate installed in a discharge gap. Spatial and electrical properties of nanosecond overvoltage discharges and Raman scattering spectra of synthesized thin films and their surfaces were investigated. Discharge plasma parameters were modeled in a mixture of Ag 2 S superionic conductor vapor and air. Numerical calculations were performed using a program that solves the Boltzmann equation for the electron energy distribution function. The transport characteristics of discharge electrons and rate constants of electronic processes were calculated depending on the values of the E / N parameter in the experimental range of 1-1000 Td of the study of discharge properties.

In this paper, a novel wide band monopole antenna is designed to operate at the millimetric wave (mmW) frequency band with impedance bandwidth of 26-70 GHz for 5G wireless communication applications. First of all a conventional antenna is designed on full ground then it designed on partial ground with size 5mm x 10mm but both designs didn’t achieve bandwidth of 50 GHz-55 GHz, The conventional antenna is a simple rectangular patch antenna with compact size 5 mm 6.5 mm. In order to generate the wideband width of 26-70 GHz a proposed antenna is designed. The design composed of rectangular patch antenna with edge-cut technique (making slots at the corner of the patch) and introduced on partial ground plane for an improved impedance matching. The suggested microstrip antenna (proposed antenna) has been designed and examined on Rogers RT5880 substrate with dimensions 10 mm 10 mm with dielectric constant 2.2, loss tangent 0.0009 and thickness of 1.57 mm using computer simulation tool (CST) software 2019. The results reveal that the antenna shows a return loss under – 10 dB over a range from 26-70 GHz and resonated at multiple frequencies 29 GHz, 32.8 GHz, 42 GHz, 47 GHz, 56.6 GHz, and 66 GHz. The gain varies from 6 dBi to 11.9 dBi with maximum obtained value at the frequency of 70 GHz, the antenna exhibits a broadside radiation pattern at both resonant frequencies 32.8 GHz and 56.6 GHz and realized gain are 7.24 dBi and 8.72 dBi at both frequencies respectively therefore the simulated outcomes of return loss, gain , radiation pattern and realized gain show the ability of the super wideband antenna to suit 5G mmW applications.
