Journal of Electrochemistry

Taking advantage of the extremely small size of the gold nanodisk electrode, the single hydrogen nanobubble generated on the surface of the nanoelectrode was studied to evaluate its hydrogen evolution performance. It was found that compared with the bare gold nanodisk electrode, the bubble formation potential of the gold nanodisk electrode modified with tungsten disulfide quantum dots (WS₂ QDs) on the surface was more positive, indicating that its hydrogen evolution activity was higher. Microdynamic model analysis shows that the average standard rate constant of the rate-determining step of the hydrogen evolution reaction of gold nanoelectrodes modified with WS_{2 …}

Platinum Nanoparticle-Based Collision Electrochemistry For Rapid Detection Of Breast Cancer Mcf-7 Cells, Fu-Xing Qin, Ming-Ke Li, Hui-Long Zhou, Wei Wen, Xiu-Hua Zhang, Sheng-Fu Wang, Zhen Wu

Journal of Electrochemistry

Cancer metastasis is the leading cause of death in cancer patients worldwide and one of the major challenges in treating cancer. Circulating tumor cells (CTCs) play a pivotal role in cancer metastasis. However, the content of CTCs in peripheral blood is minimal, so the detection of CTCs in real samples is extremely challenging. Therefore, efficient enrichment and early detection of CTCs are essential to achieve timely diagnosis of diseases. In this work, we constructed an innovative and sensitive single-nanoparticle collision electrochemistry (SNCE) biosensor for the detection of MCF-7 cells (human breast cancer cells) by immunomagnetic separation technique and liposome signal …

Optimizing In-Situ Upgrading Of Heavy Crude Oil Via Catalytic Aquathermolysis Using A Novel Graphene Oxide-Copper Zinc Ferrite Nanocomposite As A Catalyst, Attia Attia, Ahmed Ashraf Soliman Eng., Mostafa Aboul-Fetouh Prof., Sayed Gomaa Prof., Tarek Aboul-Fotouh Prof.

Petroleum Engineering and Gas

Unconventional resources, such as heavy oil, are increasingly being explored and exploited due to the declining availability of conventional petroleum resources. Heavy crude oil poses challenges in production, transportation, and refining, due to its high viscosity, low API gravity, and elevated sulfur and metal content. Improving the quality of heavy oil can be achieved through the application of steam injection, which lowers the oil’s viscosity and enhances its flow. However, steam injection alone falls short of meeting the growing demand for higher-quality petroleum products. Catalytic upgrading is therefore being investigated as a viable solution to improve heavy oil quality. This …

Assessing The Effectiveness Of Chatbots In Providing Personalized Academic Advising And Support To Higher Education Students: A Narrative Literature Review, Manal Dawood

2020-Current year OA Pubs

As a potent and convenient genome-editing tool, Cas9 has been widely used in biomedical research and evaluated in treating human diseases. Numerous engineered variants of Cas9, dCas9 and other related prokaryotic endonucleases have been identified. However, as these bacterial enzymes are not naturally present in mammalian cells, whether and how bacterial Cas9 proteins are recognized and regulated by mammalian hosts remain poorly understood. Here, we identify Keap1 as a mammalian endogenous E3 ligase that targets Cas9/dCas9/Fanzor for ubiquitination and degradation in an 'ETGE'-like degron-dependent manner. Cas9-'ETGE'-like degron mutants evading Keap1 recognition display enhanced gene editing ability in cells. dCas9-'ETGE'-like degron …

Joint Modeling Of Degradation Signals And Time-To-Event Data For The Prediction Of Remaining Useful Life, Sebastian Brumm, Erik Linstead, Junde Chen, Narayanaswamy Balakrishnan, Yuxin Wen

Engineering Faculty Articles and Research

Accurate prediction of remaining useful life (RUL) for in-service systems plays an important role in ensuring efficient operation of industrial equipment and in preventing unexpected equipment failures. In this paper, we present a prognostic framework for real-time RUL prediction based on joint modeling of both degradation signals and time-to-event data. The proposed model employs a change point-based general path model to capture signal non-linearity and Neural network (NN) based Cox model to link the time-to-event data with the estimated degradation trend. An empirical two-step scheme for hyperparameter estimation is proposed to enhance prognostic accuracy. Furthermore, an efficient Bayesian model updating …

Exploring The Interconnectivity Between Soilless Substrate Hydraulic Properties And Plant Root Morphology, Kristopher S. Criscione

LSU Doctoral Dissertations

Horticultural container production heavily relies upon porous soilless substrates to mass produce specialty crops. Soilless substrates are responsible for continuously maintaining optimal water, mineral nutrients, and air balances to promote healthy root growth and support productive shoot yield (foliage or fruit). Increasing evidence of substrate research continues to highlight the strong relationships associated with root development and substrate physiochemical properties. Despite the importance of the root system for overall plant health, most horticultural research to-date has focused on shoot development. Research tends to report total root biomass as the primary root-growth metric; however, this results in several developmental features becoming …

Design Of End Bent Piles For Downdrag, Tanna Frye

USF Tampa Graduate Theses and Dissertations

Embankments are commonly used for bridge approaches, with mechanically stabilized earth (MSE) walls being the preferred choice in Florida. However, the construction of embankments leads to the settlement of the underlying soil, regardless of soil type. When piles are driven before embankment construction, the initial settlement of the original soil creates relative movement between the pile and the surrounding soil, introducing frictional forces. When the existing soils move downward relative to the pile, a downward-oriented side shear known as downdrag is introduced. While downdrag is addressed in current codes and textbooks, it is often only briefly mentioned and primarily in …
