Utilizing the Potential of Polyvinylidene Fluoride in Developing Durable Superhydrophobic and Antibacterial Nanocomposite Coatings for Oil/Water Separation
...Show More Authors
ABSTRACT<p> The increasing demand for durable and multifunctional separation materials necessitates polymer‐based coatings that combine mechanical robustness with high selectivity. This study aims to develop antibacterial oil/water separation systems that effectively address challenges posed by microorganisms, which can decrease filter effectiveness and impact overall separation efficiency. Metal meshes were coated with titanium dioxide (TiO <sub>2</sub> ), octadecanethiol (ODT), and polyvinylidene fluoride (PVDF) via spray coating using four formulations: TiO <sub>2</sub> , PVDF, TiO <sub>2</sub> /ODT, and TiO <sub>2</sub> /ODT/PVDF. PVDF‐containing coatings exhibited superior superhydrophobicity, with a water contact angle of 161° and a sliding angle of 3°, attributed to the dense nano‐roughened texture formed upon drying. The ODT contributed to uniform surface coverage, while PVDF imparted excellent adhesion and mechanical durability, maintaining self‐cleaning performance after 50 abrasion cycles. The TiO <sub>2</sub> /ODT/PVDF formulation demonstrated the highest oil/water separation efficiency and improved oil flux, highlighting the critical contribution of the polymer–nanoparticle interface. Moreover, the nanocomposite coating exhibited pronounced antibacterial activity against <italic> <styled-content style="fixed-case">S</styled-content> taphylococcus <styled-content style="fixed-case">aureus</styled-content> </italic> (98.7%) and <styled-content style="fixed-case"> <italic>Escherichia coli</italic> </styled-content> (99.2%). These findings underline the potential of polymer‐based nanocomposite coatings as scalable and multifunctional materials for advanced oil/water separation technologies. </p>

Counseling program efficiency in developing emotional competence of intermediate school students
...Show More Authors

Emotional competence, is relatively a new concept, stands for the ability of people to perceive their feelings and emotions, and sharing them with others. It also refers to capability in optimizing these feeling and emotions, and managing them over various situations. Thus, this study aims to examine the efficiency of counseling program in developing an emotional competence among intermediate school students in Baghdad city. The sample included group of female students at intermediate stage. The findings revealed none of experimental and control groups have statistically significant differences in pre-posttests of emotional competence efficiency.

The Study was achieved adjectives physical and chemical water wells in the district of
Samarra , where a study has 42 sample groundwater in different regions of the judiciary
randomly distributed all over the judiciary and examined in vitro.
The study showed that the quality of groundwater in the general area of study
Kipritateh punctuated Klordih water quality and other quality Bicarboonatih.
Varied the key components of groundwater in the study area in concentrations
between periods of rain and drought, especially because of the cation ion exchange processes
as well as mitigation as a result of filtering rain water and dominated the calcium ion,

Eco-friendly and Secure Data Center to Detection Compromised Devices Utilizing Swarm Approach
...Show More Authors

Modern civilization increasingly relies on sustainable and eco-friendly data centers as the core hubs of intelligent computing. However, these data centers, while vital, also face heightened vulnerability to hacking due to their role as the convergence points of numerous network connection nodes. Recognizing and addressing this vulnerability, particularly within the confines of green data centers, is a pressing concern. This paper proposes a novel approach to mitigate this threat by leveraging swarm intelligence techniques to detect prospective and hidden compromised devices within the data center environment. The core objective is to ensure sustainable intelligent computing through a colony strategy. The research primarily focusses on the

Improved DDoS Detection Utilizing Deep Neural Networks and Feedforward Neural Networks as Autoencoder
...Show More Authors

Software-defined networking (SDN) is an innovative network paradigm, offering substantial control of network operation through a network’s architecture. SDN is an ideal platform for implementing projects involving distributed applications, security solutions, and decentralized network administration in a multitenant data center environment due to its programmability. As its usage rapidly expands, network security threats are becoming more frequent, leading SDN security to be of significant concern. Machine-learning (ML) techniques for intrusion detection of DDoS attacks in SDN networks utilize standard datasets and fail to cover all classification aspects, resulting in under-coverage of attack diversity. This paper proposes a hybr

The use of laurylamine hydrocholoride CH3(CH2)11 NH3 –Cl for secondary oil recovery
...Show More Authors

Laurylamine hydrochloride CH3(CH2)11 NH3 – Cl has been chosen from cationic surfactants to produce secondary oil using lab. model shown in fig. (1). The relationship between interfacial tension and (temperature, salinity and solution concentration) have been studied as shown in fig. (2, 3, 4) respectively. The optimum values of these three variables are taken (those values that give the lowest interfacial tension). Saturation, permeability and porosity are measured in the lab. The primary oil recovery was displaced by water injection until no more oil can be obtained, then laurylamine chloride is injected as a secondary oil recovery. The total oil recovery is 96.6% or 88.8% of the residual oil has been recovered by this technique as shown
