Studies on the titanium dioxide nanoparticles: biosynthesis, applications and remediation
Springer Science and Business Media LLC - Tập 1 - Trang 1-9 - 2019
Nanoparticles have wide applications in various fields due to their small size. Titanium dioxide nanoparticles are bright with high refractive index (n = 2.4) which makes them suitable for industry dealing with toothpaste, pharmaceuticals, coatings, papers, inks, plastics, food products, cosmetics and textile. Three crystalline phases of titanium dioxide, are anatase (tetragonal), rutile (tetragon......
Modeling dynamic mechanical system behavior using sequence modeling of embodiment function relations: case study on a hammer mechanism
Springer Science and Business Media LLC - Tập 3 - Trang 1-17 - 2021
In engineering design, an issue for using complex simulation models in system analysis are unknown causes for dynamic system behavior, which make parameterization difficult. This paper presents a case study in which a structured system analysis is used for the parameterization of complex dynamic multi-domain models. The dynamic system behavior of an impact wrench during fastening of a bolt is anal......
Three-layer model for the control of epidemic infection over multiple social networks
Springer Science and Business Media LLC - - 2023
This paper presents a hierarchical approach for controlling the spread of an epidemic disease. The approach consists of a three-layer architecture where a set of two-layer multiple social networks is governed by a (third) top-layer consisting of an optimal control policy. Each of the two-layer social networks is modeled by a microscopic Markov chain. On top of all the two-layer networks is an opti......
Geophagic clay around Uteh-Uzalla near Benin: mineral and trace elements compositions and possible health implications
Springer Science and Business Media LLC - Tập 3 - Trang 1-12 - 2021
Geophagic clay consumption, which is an age-long cultural practice by humans and animals in many parts of the world, and particularly in Nigeria, may have long time health effects on the consumers. This is particularly so because of the relatively high concentration of harmful minerals and toxic elements. This study sought to determine the mineralogical and trace element compositions of geophagic ......
Assembly of quinone-based renewable biobattery using redox molecules from Lawsonia inermis
Springer Science and Business Media LLC - Tập 1 - Trang 1-7 - 2019
The current study tested the hypothesis whether common plant extracts could be used as redox molecules in biobattery. Natural quinone molecules were extracted from Lawsonia inermis (henna) via sequential extraction using hexane, ethyl acetate, methanol and 80% methanol in water, followed by purification using column chromatography to examine their potential function as redox molecules in biobatter......
Tác động của việc gia cường bằng vi hạt SiC/Si3N4 đến các thuộc tính cơ học và khả năng chống mài mòn của mối hàn nhôm hợp kim AA6061-T6 bằng phương pháp hàn trộn ma sát Dịch bởi AI
Springer Science and Business Media LLC - Tập 2 - Trang 1-11 - 2020
Hàn trộn ma sát (FSW) được sử dụng rộng rãi để kết nối các thành phần hợp kim nhôm trong các ứng dụng xây dựng, hàng không và ô tô. Trong nghiên cứu này, các thuộc tính cơ học (độ bền kéo, tỷ lệ kéo dài và độ cứng vi mô), tính chất chống mài mòn và cấu trúc vi mô của mối hàn trộn ma sát của AA6061-T6 đã được nghiên cứu bằng cách gia cường giữa các tấm bằng vi hạt silicon carbide (µSiC) và vi hạt s......

Facile one-pot synthesis of water-soluble fcc FePt3 alloy nanostructures
Springer Science and Business Media LLC - Tập 2 - Trang 1-8 - 2020
Proccessible FePt3 alloy nanoparticles with sizes smaller than 50 nm open the avenue to novel magnetic sensor, catalytic and biomedical applications. Our research objective was to establish a highly scalable synthesis technique for production of single-crystalline FePt3 alloy nanoparticles. We have elaborated a one-pot thermal decomposition technique for the synthesis of superparamagnetic FePt3 na......
Highly efficient removal of As(V) using metal–organic framework BUC-17
Springer Science and Business Media LLC - Tập 2 - Trang 1-11 - 2020
Arsenic contamination is a great threat worldwide due to its toxicity and hardly degradable. The development of highly efficient adsorbents is an essential challenge in the water treatment field. A 2D metal–organic framework [Co3(tib)2(H2O)12](SO4)3 (BUC-17) has been synthesized by hydrothermal method, and was utilized as an efficient adsorbent to remove As(V) from contaminated water. The results ......
Analysis of the implementation of microgrid: case study of wide-area Bjelimići
Springer Science and Business Media LLC - Tập 1 - Trang 1-9 - 2018
Microgrids are increasingly put forward as key concepts of future energy supply, complementing as well as transforming the conventional, centralized energy system. Here, the aim was to construct microgrid composed of wind and solar power plants, diesel generator and battery storage which will be independent of a large, centralized electricity grid and incorporate more than one type of power source......
Detection of colon cancer based on microarray dataset using machine learning as a feature selection and classification techniques
Springer Science and Business Media LLC - Tập 2 - Trang 1-8 - 2020
Microarray data is an increasingly important tool for providing information on gene expression for analysis and interpretation. Researchers attempt to utilize the smallest possible set of relevant gene expression profiles in most gene expression studies to enhance tumor identification accuracy. This research aims to analyze and predicts colon cancer data employing a machine learning approach and f......
