Effects Of Cobalt Salts On Biomass Conversion To Functional Carbon-Based Catalysts For Peroxymonosulfate Activation, Zhihao Tian, Qianru Chen, Shiying Ren, Huayang Zhang, Wenjie Tian, Hongqi Sun, Shaobin Wang

Research outputs 2022 to 2026

Metal functionalization is an effective structure-engineering strategy for preparing biomass-derived carbon materials, whereas the influences of different metal precursors on the structure and catalytic performance remain unclear. Herein, an investigation of four typical cobalt salts for pyrolytic biomass conversion is performed. The melting points and anion species of cobalt salts are found to be critical factors. Co-salts (cobalt nitrate (Co(NO3)2), cobalt acetate (Co(OAc)2), cobalt acetylacetonate (Co(acac)2)) melted at low temperatures ( ≤ 165 °C) could promote mesopore formation and catalyze the graphitization process of a biomass flower during the carbonization, finally forming mesoporous graphitic carbon matrixes with Co@graphitic-C nanoparticles and …

Understanding Undergraduate Student Borrowing In China: A Qualitative Analysis, Hanwen Zhang

Journal of Student Financial Aid

As China moved from elite to mass higher education, student borrowers as the product of state intervention have surged. Yet little attention has been paid to their voices. This study conducts reflexive thematic analysis with a qualitative inquiry into lived experiences of 41 current borrowers. A five-factor typology of debt attitudes yields a dynamic explanation of debt and repayment complexities. Students perceive borrowing as an investment in human and social capital. They are, however, cautious of consumer credit. Far from being a deterrent or added burden, educational indebtedness grants them a measure of freedom and autonomy in college. And they …

Gender And Loans: Understanding Differences In Student Debt Burden, Rong Chen, Katie N. Smith

Journal of Student Financial Aid

Based on combined data from Baccalaureate & Beyond (B&B:16/17), Integrated Postsecondary Education Data System (IPEDS), and Barron’s Profiles of American Colleges, this study utilizes zero-inflated beta regression methods and analyzes individual and institutional factors that predict debt burden by gender. Results show that women are less likely than men to have a zero debt burden one year after college graduation. Interaction effect tests show that the relationship between gender and zero debt burden differs by race/ethnicity. Additional analyses disaggregating the debt and earnings components indicate that women’s salary is significantly lower than men’s. The combined results of lower probability of …

Neural Network Learning For Pdes With Oscillatory Solutions And Causal Operators, Lizuo Liu

Mathematics Theses and Dissertations

In this thesis, we focus on developing neural networks algorithms for scientific computing. First, we proposed a phase shift deep neural network (PhaseDNN), which provides a uniform wideband convergence in approximating high frequency functions and solutions of wave equations. Several linearized learning schemes have been proposed for neural networks solving nonlinear Navier-Stokes equations. We also proposed a causality deep neural network (Causality-DeepONet) to learn the causal response of a physical system. An extension of the Causality-DeepONet to time-dependent PDE systems is also proposed. The PhaseDNN makes use of the fact that common DNNs often achieve convergence in the low frequency …

Eyes are one of the main critical organs of the body that provide our brain with the most information about the surrounding environment. Disturbance in the activity of this informational organ, resulting from different ocular diseases, could affect the quality of life, so finding appropriate methods for treating ocular disease has attracted lots of attention. This is especially due to the ineffectiveness of the conventional therapeutic method to deliver drugs into the interior parts of the eye, and the also presence of barriers such as tear film, blood-ocular, and blood-retina barriers. Recently, some novel techniques, such as different types of …

Tutorial: Using Neuron For Neuromechanical Simulations, Hillel J. Chiel, Peter J. Thomas

Faculty Scholarship

The dynamical properties of the brain and the dynamics of the body strongly influence one another. Their interaction generates complex adaptive behavior. While a wide variety of simulation tools exist for neural dynamics or biomechanics separately, there are few options for integrated brain-body modeling. Here, we provide a tutorial to demonstrate how the widely-used NEURON simulation platform can support integrated neuromechanical modeling. As a first step toward incorporating biomechanics into a NEURON simulation, we provide a framework for integrating inputs from a “periphery” and outputs to that periphery. In other words, “body” dynamics are driven in part by “brain” variables, …

Transcriptional Regulation Of The Synthesis And Secretion Of Farnesol In The Fungus Candida Albicans: Examination Of The Homann Transcription Regulator Knockout Collection, Daniel Gutzmann, Jaxon J. Kramer, Brigid M. Toomey, Cory Honsinger Thomas Boone, Audrey L. Atkin, Kenneth Nickerson

School of Biological Sciences: Faculty Publications

Candida albicans is an efficient colonizer of human gastrointestinal tracts and skin and is an opportunistic pathogen. C. albicans exhibits morphological plasticity, and the ability to switch between yeast and filamentous morphologies is associated with virulence. One regulator of this switch is the quorum sensing molecule farnesol that is produced by C. albicans throughout growth. However, the synthesis, secretion, regulation, and turnover of farnesol are not fully understood. To address this, we used our improved farnesol assay to screen a transcription regulator knockout library for differences in farnesol accumulation in whole cultures, pellets, and supernatants. All screened mutants produced …
