Synthesis and characterization of 4-nitro benzaldehyde with ZnO-based nanoparticles for biomedical applications
Globally, cancer is the leading cause of death and morbidity, and skin cancer is the most common cancer diagnosis. Skin problems can be treated with nanoparticles (NPs), particularly with zinc oxide (ZnO) NPs, which have antioxidant, antibacterial, anti-inflammatory, and anticancer properties. An antibacterial activity of zinc oxide nanoparticles prepared in the presence of 4-nitrobenzaldehyde (4NB) was also tested in the present study. In addition, the influence of synthesized NPs on cell apoptosis, cell viability, mitochondrial membrane potential (MMP), endogenous reactive oxygen species (ROS) production, apoptosis, and cell adhesion was also examined. The synthesized 4-nitro benzaldehyde with ZnO (4NBZnO) NPs were confirmed via characterization techniques. 4NBZnO NPs showed superior antibacterial properties against the pathogens tested in antibacterial investigations. As a result of dose-based treatment with 4NBZnO NPs, cell viability, and MMP activity of melanoma cells (SK-MEL-3) cells were suppressed. A dose-dependent accumulation of ROS was observed in cells exposed to 4NBZnO NPs. As a result of exposure to 4NBZnO NPs in a dose-dependent manner, viable cells declined and apoptotic cells increased. This indicates that apoptotic cell death was higher. The cell adhesion test revealed that 4NBZnO NPs reduced cell adhesion and may promote apoptosis of cancer cells because of enhanced ROS levels. 2023 Wiley-VCH GmbH. -
Calcination process of porous metalorganic frameworks derived from nickel sulfide composites for supercapacitor and computer vision for investigating the porosity-electrochemical correlation
The utilization of metalorganic framework nanostructured electrode materials in supercapacitors and sensor applications is achieved by various chemical methods. In this study, we create NiS and NiS@MOF-BDC by employing nickel precursors and benzene dicarboxylic acid (BDC) as chelating organic linkers through a thermal reduction procedure at a temperature of 400 C to produce the composite. The composite heterostructure enhanced the conductivity, porous characteristics, and diverse potential morphological qualities. The production of composite electrodes demonstrates a specific capacity of 260F/g (104C/g) when subjected to a current density of 1A/g. Additionally, these electrodes exhibit exceptional cyclic stability, enduring 5000 cycles, when used with a 2 M KOH electrolyte. Moreover, the synthesized composite HR-TEM images were analyzed using computer vision and AI techniques for estimating the porosity and investigating the enhanced electrochemical correlation. 2024 Elsevier B.V. -

File Validation intheData Ingestion Process Using Apache NiFi
In the industries of today, development and maintenance of data pipelines is of paramount importance. With large volumes of data being generated across industries on a continuous basis, there is a growing need to process and store this ingested data in a fast, and efficient manner. Apache NiFi is one such tool which possesses crucial capabilities that can be used to enhance, modify, and automate data pipelines. However, automation of the ingestion process creates certain inherent issues which, without being resolved, tend to be detrimental to the entire ingestion process. These issues vary in nature, ranging from corrupted data to changes in the file schema, to name a few. In this paper, a solution to this problem is proposed. By exploiting Apache NiFis custom processor development capabilities, problem-specific processors can be designed and deployed which can ensure accurate validation of the ingestion process on a real-time basis. To demonstrate this, two processors were developed as a proof-of-concept, which tackle specific file-related validation issues in the ingestion processthat of the file size, and, the ingestion frequency. These custom-built processors are designed to be inserted into the pipeline at key points to ensure that the ingested data is validated against certain standards and requirements. Having successfully demonstrated its capabilities, the paper presents the exploitation of Apache NiFis custom processor capabilities as a potential way forward to resolve the plethora of ingestion issues in industry, today.

Each sector of the digital world generates enormous data as human life continues to transform. Areas like data analytics, data science, knowledge discovery in databases (KDD), machine learning, and artificial intelligence depend on highly distributed data which requires appropriate storage in a data lake. Collecting the data from different heterogeneous sources and creating a single lake of data is called data ingestion. Ironically, data ingestion has been treated as a less important stage in data analysis because it is considered a minor first step. There are several misconceptions in the data and analytics domain about data ingestion. The survey employed in this research presents a list of significant challenges faced by information technology (IT) industries during data ingestion. The available frameworks are compared in terms of standard parameters that are set against the existing challenges and myths. The findings from the comparison are compiled in a tabular format for easy reference.

The design and analysis of helical cross - Axis wind turbine
Environmental conditions such as high turbulence, low wind speed, and persistent changes in oncoming wind direction can minimize the performance of a horizontal axis wind turbine (HAWT). Some specific vertical axis wind turbine (VAWT) designs can work fine in these rare functioning conditions but still, they pose an occasional power coefficient. So a unique design of a helical cross-axis wind turbine (HCAWT) was modeled which will operate under multiple wind directions such as horizontal wind stream and vertical wind stream from the underside of the turbine. The HCAWT consists of three helical vertical blades and six horizontal blades arranged in cross-axis orientation for enhancing its performance and self-starting behavior. The obtained analysis study results show that the power generated by the HCWAT was improved when compared to the Straight-Bladed VAWT. Both the turbines were placed at height of 100, 150, 200 & 250?mm in the simulation study, coefficient of power (Cp) achieved by HCAWT was 0.43, 0.52, 0.48, and 0.51 at an RPM of 554, 512, 474 and 449 respectively whereas in the case of Straight-Bladed VAWT was 0.15, 0.18, 0.13 and 0.23 at an RPM of 179, 189, 212 and 233 were obtained. 2022 Author(s). -

Use of zeolite and industrial waste materials in high strength concrete - A review
Concrete is widely used in construction material by the construction industry. It is considered as a vital material because of its properties. Different grades of concrete (M10, M20, M30, M40, M50, M60and M70) are used in construction and are chosen based on the requirements. Higher grade concrete requires cement of different properties. The manufacturing process of cement, releases a huge amount of Carbon footprints. To reduce the emission of CO2, usage of virgin cement can be minimized by partially replacing with pozzolanic materials or industrial wastes like zeolite, metakaolin, silica fume and fly ash. These materials improve the durability and strength of concrete by filling the pores and reduce the porosity and permeability of the concrete without compromising on the desired properties. For sustainable development and protecting the environment, enormous research has been done on concrete by using various industrial waste materials. This article is a state-of-the-art review of research on the use of industrial waste materials to produce High Strength Concrete (HSC). Different materials were studied to prepare HSC by using distinct methods. Different experimental tests were conducted on concrete when cement is partially replaced with industrial waste materials and are compared with conventional concrete. It is observed that the partial replacement of cement with zeolite, metakaolin, fly ash, and silica fume, the properties of concrete increases up to certain age and mixing proportions when compared to conventional concrete. It is observed that there is limited research was done on zeolite with the combination of industrial waste materials for health analysis of the structures at different w/c ratios for large production. So, further investigation is needed on the technical, environmental, economic aspects and educating the public through the use of industrial waste materials as a sustainable approach. 2021 Elsevier Ltd.

Mathematical Modeling for Evaluating the Mechanical Properties of High Strength Concrete with Natural Zeolite and Additives
The cement manufacturing industry is a major contributor to atmospheric pollution, primarily due to carbon dioxide emissions. Consequently, there is a pressing need to develop eco-friendly concrete capable of mitigating air pollution by sequestering atmospheric carbon dioxide. In this context, the incorporation of Natural Zeolite in concrete has been investigated, as it can absorb environmental carbon dioxide. This study explored the effects of partial cement replacement with Natural Zeolite (5%) and varying percentages of Silica Fume, Metakaolin, and Fly Ash (5%, 10%, and 15%) on the mechanical properties and carbon sequestration potential of High Strength Concrete (HSC). Comprehensive testing was conducted to evaluate the split tensile, compressive, and flexural strengths of the modified HSC. Experimental results indicated that the addition of Natural Zeolite and Metakaolin enhanced the strength of HSC, with Mix 3 displaying a higher 90-day compressive strength compared to the reference mix. The findings suggest that incorporating Natural Zeolite and other supplementary cementitious materials in concrete has the potential to alleviate environmental pollution. The dataset, comprising 900 samples, exhibited no autocorrelation or multicollinearity issues, making it suitable for multiple regression analysis. The statistically significant regression models developed in this study can effectively predict concrete strength. (2023). All Rights Reserved.
