A Cold Plasma-Enabled Reduction Process For The Fabrication Of Metallic Nanostructures Onto Polymeric Biomaterials, Gerardo Hernandez-Moreno
All ETDs from UAB
The design and manufacture of novel materials has served as the bedrock for tissue engineering and regenerative medicine. There exists a need for more biocompatible implantable materials in the biomedical device space. The approach to developing biomaterials fit for biomedical devices has been focused on decreasing overall physiological interaction with the local environment. However, the development of more biomechanically favorable materials has placed an emphasis on designing materials that display biomimetic and biomechanical properties resembling that of the host tissue at the implant site. As biomaterials engineering has progressed, the race to find materials that interact at the nano- and …
Zero-Sequence Current In Cable Systems: A Study, Shimaa A. F. Salem, Rabab R. M. Eiada, Ebrahim A. Badran
Zero-Sequence Current In Cable Systems: A Study, Shimaa A. F. Salem, Rabab R. M. Eiada, Ebrahim A. Badran
Mansoura Engineering Journal
Large zero-sequence current is not a new phenomenon for cable bus duct systems; the question is what influences its magnitude. It was found that the zero-sequence currents were circulating between different circuits in the cable system and that they were being generated by induction between phases in the same cable route. It was determined that the zero-sequence currents could be greatly reduced in a twin circuit by symmetrical configuration of the cables. However, in a four-circuit system, no significant reduction could be achieved even by the symmetrical configuration. Therefore, in this paper, this phenomenon will be analyzed and discussed. ATPDraw …

Mechanical And Impact Properties Of Fibrous Rubberized Geopolymer Concrete, Metwally Abd Allah Abd-Elaty, Mariam Farouk Ghazy, Omar Hussein Khalifa
Mansoura Engineering Journal
Geopolymer concrete significantly contributes to reducing harmful emissions by reducing the cement industry and replacing it with by-product materials produced by different industries. Geopolymers have enhanced mechanical properties compared with cementitious products, however, their ductility and impact resistance tend to be relatively low. Additionally, the used rubber tires provide a significant environmental risk. Consequently, this research's primary objective is to develop and investigate improved rubberized geopolymer concrete concerning ductility and impact resistance. Reusing Crumb Rubber (CR) as an alternative to natural sand was investigated to meet these goals using volume replacement ratios of (3%, 6%, and 9%). Additionally, different volume …

We investigated interactions between Ti6Al4V alloys and strontium zirconate (SrZrO3) ceramic to assess its potential as a refractory mold material in investment casting. We developed a robust yet simple procedure to examine both the liquid–solid and solid–solid interactions using pellets in drop casting and diffusion couple methods. Reaction layers were characterized using optical microscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and x-ray diffraction (XRD). The results were compared to alumina (Al2O3) which is still a common refractory ceramic for molds in investment casting. Our findings indicate that Ti6Al4V surfaces in contact with …

A Data-Driven Scheduling Approach For Integrated Electricity-Hydrogen System Based On Improved Ddpg, Yaping Zhao, Jingsi Huang, Endong Xu, Jianxiao Wang, Xiaoyun Xu
Graduate School of Business Publications
The involvement of hydrogen energy systems has been recognised as a promising way to mitigate climate problems. As a kind of efficient multi-energy complementary system, the hydropower-photovoltaic-hydrogen (HPH) system could be an ideal approach to combining hydrogen with an installed renewable energy system to improve the flexibility of energy management and reduce power curtailment. However, the intra-day scheduling of HPH system brings challenges due to the time-related nonlinear hydropower generation process, the complex energy conversion process and the uncertain natural resource supply. Faced with these challenges, an improved deep deterministic policy gradient (DDPG)-based data-driven scheduling algorithm is proposed. In contrast …
Synthesis Of Quasi-Freestanding Graphene Films Using Radical Species Formed In Cold Plasmas, Michael A. Mathews Jr.
Synthesis Of Quasi-Freestanding Graphene Films Using Radical Species Formed In Cold Plasmas, Michael A. Mathews Jr.
Graduate Theses, Dissertations, and Problem Reports
For over a decade, the Stinespring laboratory has investigated scalable, plasma assisted synthesis (PAS) methods for the growth of graphene films on silicon carbide (SiC). These typically utilized CF4-based inductively coupled plasma (ICP) with reactive ion etching (RIE) to selectively etch silicon from the SiC lattice. This yielded a halogenated carbon-rich surface layer which was then annealed to produce the graphene layers. The thickness of the films was controlled by the plasma parameters, and overall, the process was readily scalable to the diameter of the SiC wafer.
The PAS process reproducibly yielded two- to three-layer thick graphene films …

Thermal Effect During Laser-Induced Plasmonic Heating Of Polyelectrolyte-Coated Gold Nanorods In Well Plates, Sujin Jiracheewanun, Michael B. Cortie, Dakrong Pissuwan
Faculty of Engineering and Information Sciences - Papers: Part B
We examined the generation and transfer of heat when laser irradiation is applied to water containing a suspension of gold nanorods coated with different polyelectrolytes. The ubiquitous well plate was used as the geometry for these studies. The predictions of a finite element model were compared to experimental measurements. It is found that relatively high fluences must be applied in order to generate biologically relevant changes in temperature. This is due to the significant lateral heat transfer from the sides of the well, which strongly limits the temperature that can be achieved. A 650 mW continuous-wave (CW) laser, with a …
A New Economic Dispatch For Coupled Transmission And Active Distribution Networks Via Hierarchical Communication Structure, Wael T. El-Sayed, Ahmad Sa Awad, Maher Azzouz, Mostafa F. Shaaban
A New Economic Dispatch For Coupled Transmission And Active Distribution Networks Via Hierarchical Communication Structure, Wael T. El-Sayed, Ahmad Sa Awad, Maher Azzouz, Mostafa F. Shaaban
Electrical and Computer Engineering Publications
Traditionally, the economic dispatch problem (EDP) of the bulk generators connected to transmission networks (TNs) is solved in a centralized dispatching center (CDC) while modeling distribution networks as passive loads. With the increasing penetration levels of distributed generation, coordinating the economic dispatch between TNs and active distribution networks (ADNs) became vital to maximizing system efficiency. This article proposes a hierarchical communication structure, which requires minimal upgrades to the CDC, for solving the EDP of coupled TNs and ADNs. Based on the minimal data transfer between the CDC and distribution network operators, the problem is formulated and solved while considering the …

High Energy Blue Light Induces Oxidative Stress And Retinal Cell Apoptosis, Jessica Malinsky
High Energy Blue Light Induces Oxidative Stress And Retinal Cell Apoptosis, Jessica Malinsky
Capstone Showcase
Blue light (BL) is a high energy, short wavelength spanning 400 to 500 nm. Found in technological and environmental forms, BL has been shown to induce photochemical damage of the retina by reactive oxygen species (ROS) production. Excess ROS leads to oxidative stress, which disrupts retinal mitochondrial structure and function. As mitochondria amply occupy photoreceptors, they also contribute to oxidative stress due to their selectively significant absorption of BL at 400 to 500 nm. ROS generation that induces oxidative stress subsequently promotes retinal mitochondrial apoptosis. BL filtering and preventative mechanisms have been suggested to improve or repair BL-induced retinal damage, …

Although it is known that practicing a motor skill updates the associated internal model, it is still unclear as to how cortical oscillations linked with the motor skill change under differing practice schedules. The current study investigated α- and β-power changes associated with motor skill acquisition. Firstly, we investigated the behavioral effects of practice on motor learning and retention during repetitive (RP) and variable (VP) practice schedules on an anticipation timing task. Secondly, we investigated changes in cortical α (10-13 HZ) and β (15-30 Hz) event-related synchronization and dyssynchronization (ERS/ERD) under RP and VP during early (EP) and late …

Engineering and Physics Faculty Research and Publications
Contrary to common stereotypes, engineering education and practice are not purely rational activities. Emotions, just like cognition, play important roles in teaching, learning, and professional practice. Today, there is a nascent body of research exploring emotions in engineering education (EEE). However, much of the existing research does not adequately theorize emotions, and the range of theories and methods used is still relatively narrow. With this chapter, we hope to inspire more investigators to conduct EEE research and to explore currently underutilized theories, methods, and research foci. This chapter introduces the reader to the multidisciplinary field of emotion research, then focus …

Combinedeepnet: A Deep Network For Multistep Prediction Of Near-Surface Pm2.5 Concentration, Prasanjit Dey, Soumyabrata Dev, Bianca Schoen-Phelan
Conference papers
PM2.5 is a type of air pollutant that can cause respiratory and cardiovascular problems. Precise PM2.5 ( μg/m3 ) concentration prediction may help reduce health concerns and provide early warnings. To better understand air pollution, a number of approaches have been presented for predicting PM2.5 concentrations. Previous research used deep learning models for hourly predictions of air pollutants due to their success in pattern recognition, however, these models were unsuitable for multisite, long-term predictions, particularly in regard to the correlation between pollutants and meteorological data. This article proposes the combine deep network (CombineDeepNet), which combines multiple deep networks, including a …

Dense, dual-phase (Cr,Hf,Nb,Ta,Ti,Zr)B2-(Cr,Hf,Nb,Ta,Ti,Zr)C ceramics were synthesized by boro/carbothermal reduction of oxides and densified by spark plasma sintering. The high-entropy carbide content was about 14.5 wt%. Grain growth was suppressed by the pinning effect of the two-phase ceramic, which resulted in average grain sizes of 2.7 ± 1.3 µm for the high-entropy boride phase and 1.6 ± 0.7 µm for the high-entropy carbide phase. Vickers hardness values increased from 25.2 ± 1.1 GPa for an indentation load of 9.81 N to 38.9 ± 2.5 GPa for an indentation load of 0.49 N due to the indentation size effect. Boro/carbothermal …
