Rheology Modifiers For Water-Based Slurry Pipeline Transportation: Overview, Efficiency, And Intensification, Ahmed Alalou, Mohammed El Asri, Ahmed Boulahna, Muthanna H. Al-Dahhan

Chemical and Biochemical Engineering Faculty Research & Creative Works

Owing to their cost-efficiency and eco-friendliness, water-based slurry pipelines are the state-of-the-art technology for the transportation of several types of solids such as coal, fly ash, petcoke, iron ore, phosphate rock and other minerals. This review comprehensively examines the effect of numerous commercial dispersants and novel chemical additives that are used as rheology modifiers to enhance the slurryability and fluidity of solid-water slurries at high solids loading. Several key performance parameters such as the rheological characteristics (shear stress, apparent viscosity, yields stress, and flow behavior), the potential stability, surface tension and contact angle that highlight the efficiency of the rheology …

Failed Gay Rights Amendment To Mankato's Human Rights Ordinance In Mankato, Minnesota In 1987, Kellian Clink

Library Services Publications

In 1987, small but passionate people urged the city to pass an amendment to Mankato’s existing human rights ordinance to protect LGBTQ+ communities.   Advocates argued that gays were entitled to the same rights as straight people and were looking for protection in housing and employment, particularly. They demonstrated that people had lost jobs, housing, and access to dance venues. Some opponents equated gays with promiscuity, child molestation, solicitation, sin, and AIDS; some were convinced it was not needed; some pinned their arguments on the existence of laws already on the books.  This narrative is based on articles from the local …

Ph-Compensated Hydrogen Peroxide Quantification Using A Dual-Modal Fiber-Optic Probe, Homayoon Soleimani Dinani, Bohong Zhang, Maryam Karimi, Rex E. Gerald, Shelley D. Minteer, Jie Huang

Electrical and Computer Engineering Faculty Research & Creative Works

We report a dual-modal fiber-optic probe that integrates electrochemical quantification of hydrogen peroxide (H₂O₂) with co-localized fluorescent pH sensing for pH-indexed interpretation of the H₂O₂ response. H₂O₂ is a reactive oxygen species involved in oxidative stress, inflammation, and cellular signaling, and local pH modulates both its production and electrochemical response. Many electrochemical H₂O₂ sensors exhibit pH-dependent sensitivity, creating ambiguity unless pH is measured and used for compensation, which is difficult in small, heterogeneous, or rapidly changing microenvironments. A three-electrode configuration—working (WE), counter (CE), and Ag/AgCl pseudo-reference (pRE) electrodes—is fabricated directly on the cylindrical surface of a 710-µm-diameter optical fiber using …

Graphene Oxide–Driven In Situ Bismuth Reduction Enables Highly Efficient Electroreduction Of Co2 To Formic Acid, Hao Feng, Bohong Zhang, Jie Huang, Xinhua Liang

Electrical and Computer Engineering Faculty Research & Creative Works

To enable large scale efficient electrochemical CO₂ reduction reaction (CO₂RR) to formic acid (HCOOH), it is important to develop catalysts that can be operated in a wide potential window with good stability. Herein, we successfully synthesized Bi₂O₃ catalyst supported on graphene oxide (GO) and graphene (G) and found that Bi₂O₃/GO catalyst had a better overall performance than Bi₂O₃/G. The Bi₂O₃/GO catalyst demonstrated an outstanding CO₂RR performance with a greater than 90% faradaic efficiency (FE) across a wide applied potential window …

Thermo-Mechanical Behaviour Of Metal-Coated Optical Fibers For Distributed High-Temperature Sensing: From Laboratory Characterization To Industrial Case Validation, Koustav Dey, Rony Kumer Saha, Bohong Zhang, Laura Bartlett, Jeffrey D. Smith, Ronald J. O'Malley, Jie Huang

Electrical and Computer Engineering Faculty Research & Creative Works

Reliable distributed temperature sensing in high-temperature environments remains a significant challenge due to the thermal and mechanical limitations of conventional optical fibers. In particular, polymer-coated fibers degrade above ∼300 °C due to coating failure, mechanical fragility and hydrogen ingress. Metal-coated optical fibers offer a robust alternative for harsh environments such as Electric Arc Furnaces (EAFs), aerospace engines, nuclear systems, and oil and gas wells, owing to their superior mechanical strength and hermetic sealing. In this work, a first comprehensive experimental investigation of the thermo-mechanical behavior of metal-coated optical fibers for distributed high temperature sensing is presented over a wide temperature …

BACKGROUND: There are few prospective studies of mycophenolate mofetil (MMF) versus cyclophosphamide (CYC) for pediatric lupus nephritis (pLN) and none evaluating rituximab (RTX).

METHODS: The Prospective Pediatric Lupus Nephritis Registry (ProPeL-R) enrolled patients <  21 years within 4 weeks of an initial kidney biopsy diagnostic of pLN. Demographic, clinical, and laboratory data were collected prospectively at enrollment, 3 months, 6 months, and then every 6 months thereafter for up to 5 years of follow-up. For this study, we compared patients receiving initial therapy with corticosteroids (CS) and either MMF (n = 33) vs. CYC (n = 18), and those treated with CS, either MMF or CYC, with RTX (n = 20) vs. without RTX (n = 51).

RESULTS: Histology consisted of 18% class III; 35% class IV; 25% mixed class; and 22% pure class V. Eighty-two percent were female. No significant differences in response or infection rates were identified between those receiving MMF or CYC. There was a significant increase in combined complete (CR) and partial response (PR) at 24 months with RTX use. Overall CR rates at 6 and 24 months were 35% …

Ddor: Delta Debugging For Explainable Overrefusal Testing And Repair, Qinyan Zhou, Peixin Zhang, Jun Sun, Haonan Zhang, Dongxia Wang

Research Collection School Of Computing and Information Systems

While safety alignment and guardrails help large language models (LLMs) avoid harmful outputs, they can also induce overrefusal, i.e., unwarranted rejection of benign queries that merely appear risky. We present DDOR (Delta Debugging for OverRefusal), a fully automated and explainable framework for overrefusal testing and repair in a black-box setting, where only model inputs and outputs are accessible and internal safety mechanisms remain opaque. DDOR applies delta debugging to localize minimal refusal-triggering fragments (mRTFs) that provide phrase-level, explainable evidence for why a refusal occurs. Conditioned on these mRTFs, DDOR generates diverse, context-rich prompts and performs multi-oracle validation to filter intrinsically …

Adjunctive Embolization Of Target Vessel Dissections To Improve Suitability For Fenestrated-Branched Endovascular Aortic Repair, Zemia C Ferreira, Hannah V Oden-Brunson, Ying Huang, Steven Maximus, Naveed Saqib, Erin Greenleaf, Thanila A Macedo, Gustavo S Oderich

Faculty, Staff and Students Publications

Suitability of renal-mesenteric target arteries is an essential criterion for fenestrated-branched endovascular aortic repair (FB-EVAR). We describe a staged adjunctive technique of target vessel false lumen (FL) embolization to improve suitability for FB-EVAR in patients with chronic postdissection thoracoabdominal aortic aneurysms (PD-TAAA) and dissection extension into the superior mesenteric artery (SMA). Three patients with SMA dissection and ectasia (diameter > 12-14 mm) underwent staged FL embolization with pre-emptive stent placement to optimize SMA incorporation. Using bilateral transfemoral access with intravascular ultrasound guidance, the proximal SMA true lumen was stented with an 8 L × 39 mm VBX balloon-expandable stent graft (W. …

An Eco-Inspired Emulsion Membrane Harnessed With Waste Vegetable Oil For Effective Separation Of Ibuprofen: Insights Into Stability, Performance, And Kinetics, Huma Warsi Khan, A. Vijaya Bhaskar Reddy, Parvez Alam Khan, Samsur Akm Rahman, Muhammad Moniruzzaman

Publications and Research

Emulsion liquid membranes (ELMs) have emerged as excellent alternatives for the separation and recovery of biologically active drugs (BADs) from industrial waste at trace concentrations. Conventional ELMs generally utilize toxic petroleum-based solvents (PBS) that pose environmental and health risks. Although virgin vegetable oils have been appeared as sustainable alternatives to PBS, their widespread application is limited by economic constraints, resource sustainability, and competition with the food supply. In contrast, waste vegetable oil (WVO) represents an abundant, low-cost, and eco-friendly alternative, yet its potential as a green diluent for ELMs remains largely unexplored. To address this challenge, present study investigated the …
