    Abstract Corrosion is a deteriorating process for metals and alloys. It's a significant problem in every aspect of life, from the personal to the professional spheres, and it has to be addressed as soon as possible. Losses of this size occur on a daily basis in a diverse range of industries, such as the oil and gas industry, the food processing industry, the pharmaceutical industry, the maritime industry, the automobile industry, the aerospace industry, and so on. In an effort to find a way to stop corrosion before it starts, researchers are always working to advance the state of the art in corrosion resistant technology. There are several different strategies for inhibiting corrosion that are now accessible. In order to extract organic and inorganic inhibitors, extraction processes require solvents and catalysts that are both costly and dangerous to the environment. In addition to being harmful to the environment, their method of synthesis is also inefficient. Here The use of inhibitors that are generated by plants has the potential to significantly improve both the resistance to corrosion and the efficiency of the process. They are harmless to both people and the natural environment, don't require a lot of money to implement, and can be used in a wide range of different situations and with different kinds of materials. Researchers have discovered that the plant has a number of phytochemicals that are resistant to rusting. When applied to the surface of the metal or alloy, the method of characterization reveals the characteristics and effects with regard to the material's or alloy's ability to resist corrosion. In this review, we looked at the corrosion problem in industry, why plant-extracted inhibitors are a good alternative to others, how plant-extracted inhibitors work and affect metals, and where we can make improvements using plant-extracted inhibitors to either maintain or erode the corrosion problem in industry.

    Abstract It is essential to monitor any health issues during pregnancy to ensure a safe delivery because pregnancy is crucial for both mother and child. However, developing countries have poor access to healthcare, making managing possible health risks during pregnancy challenging. An Internet of Things (IoT)-based Medical Cyber-Physical System (MCPS) can offer a valuable and affordable solution for anticipating and controlling health hazards during pregnancy to solve this issue. This paper presents the design and development of an MCPS for recognizing health risks in pregnant women in developing countries. The system collects key health metrics using temperature, blood pressure, glucose levels, and heart rate sensors. It automatically considers risk factors to predict health risks using Machine Learning (ML) and sends them to the nearest clinic or hospital. Patients can manually enter their risk factors into the program and talk with a doctor through it. The efficacy of the proposed MCPS is evaluated using a dataset of pregnant women, and the results demonstrate that the system can accurately detect health issues during pregnancy. Medical experts can.enhance maternal and fetal health outcomes using the systems real-time data collecting and processing capabilities. Despite restricted access to healthcare in developing countries, the proposed MCPS provides a valuable and economical method of addressing pregnancy-related health risks. The MCPS can assist medical personnel in making quick and informed choices, enhancing the level of care provided to expectant mothers and their unborn children.

    Abstract Climate change and increased pollution caused by traditional petrochemical plastics made the biodegradable environment-friendly plastic (bioplastic) research more popular. Bioplastics can be manufactured from natural renewable ingredients and used as food packaging material without harming the environment. This research work focuses on developing bioplastic films from natural ingredients such as starch of tamarind seeds, and berry seeds, with licorice root. Attention has been paid to characterizing the material by biodegradability, mechanical testing, Fourier Transformed Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), antimicrobial analysis tests. Phenolic compounds present in the berry seeds starch increased the soil biodegradability as well as the mechanical and thermal properties of the bioplastic films. The FTIR spectra confirmed the presence of various bio-molecules. Improved antimicrobial performance is also obtained. The results of this research confirm that the prepared bioplastic samples can be used in packaging applications.

    Abstract Polymer-based coatings are widely used as a protective barrier to corrosion, but their performance is not sufficiently sustainable for industrial applications due to the formation of micropores and microcracks during solidification. Graphene is a promising reinforcing element acting as a filler for polymeric coatings. This study used 1–5 wt% graphene synthesized by the electrochemical exfoliation process as a reinforcing nanofiller to manufacture graphene-reinforced epoxy nanocomposite (GREN) coatings. Copper was used as a substrate material for coating with GREN by a bar coating method. GREN coatings were characterized by X-ray diffraction, Raman spectroscopy, FTIR spectroscopy, FESEM, and EDX. A comprehensive investigation was conducted on the various multi-physical properties of GREN coatings, including coating thickness, surface roughness, adhesiveness, surface wettability, water absorptivity, thermal stability, electrical conductivity, and anti-corrosion capabilities. The results exhibited that graphene fills micro-pores produced in epoxy during solidification. The surface roughness significantly decreased to 0.25 µm with the addition of 5 wt% graphene in pure epoxy. In addition, the adhesiveness, thermal stability, and electrical conductivity of GREN coatings increased with the increase in graphene content. The GREN coatings containing 3 wt% and 5 wt% graphene revealed hydrophobic surface showing 94° and 102° water contact angle, respectively. In the electrochemical analysis and immersion test in 3.5 % NaCl solution for 600 h, the GREN coatings showed higher corrosion resistance without compromising their electrical conductivity compared to the pure epoxy. Based on the results, GREN can be a promising coating material for aerospace, mining, and electronic packaging applications. Apart from this, the results of this work will explore the new significance in industry, where multi-physical properties from a single nanocomposite coating are crucial.

    Abstract Dental implantology has always emphasized silver nanoparticles (AgNPs) for various applications due to their biocompatibility, antibacterial activity, and increased surface volume ratio offered by these particles. It is utilized to a large extent in the dental implant industry as a surface modification, biocompatible constituent and composite material. AgNPs may be produced inexpensively, sustainably, and environmentally responsibly by utilizing technologies that extract the plant material. The phytochemical components that are contained in plants make them a better, non-toxic, and more cost-effective alternative to both physical and chemical approaches. Because the size and shape of AgNP depend on their synthesis method and technique, and because the efficacy and toxicity of AgNP depend on both size and shape, synthesis methods and techniques have recently become the focus of a significant amount of research attention. In this review, we discussed Plant Extracted Ag-NP's whose sizes range up to 100nm. This review also focuses on recent research advancements in the Plant Extracted synthesis of AgNPs, as well as their characterization methodologies, current obstacles, future possibilities, and applications in dental implantology.
