Nanofluids are advantageous due to their superior thermophysical properties compared to base fluids. Increasing nanoparticle concentration increases thermophysical properties. However, viscosity enhancement results in increased pressure drop and pumping power requirement in the flow channel, which may limit the potential nanofluid applications. Because nanofluids is a relatively new subject, complexity of the nanofluid systems and nanofluid viscosity being affected by many parameters make the subject even more complicated. When literature is overviewed, lack of a general model for nanofluid viscosity is observed. In this study, nanofluid viscosity was investigated and given viscosity models were compared based on some effective parameters.

Systematic evolution of novel 2′F-PY RNA aptamers targeting the membrane protein l-arginine/agmatine antiporter purified in mild detergent
Ayoub, Nooraldeen; Son, Çağdaş Devrim; İlgü, Müslüm; Department of Biochemistry (2021-2-15)
Bacterial microorganisms have developed numerous and diverse systems to handle potentially detrimental acidic conditionsintheir external environment. In particular, some pathogenic and other nonpathogenic enteric bacteriahave a number of exceptionaland well-organized acid resistance (AR) mechanismsthat work together to counter intracellular acidification and damage and enable survival under the extreme acidic conditions of the mammalian stomach. The common Escherichia coliwith both its virulent ...
Accurate formation energies of charged defects in solids: A systematic approach
Vinichenko, Dmitry; Sensoy, Mehmet Gokhan; Friend, Cynthia M.; Kaxiras, Efthimios (2017-06-30)
Defects on surfaces of semiconductors have a strong effect on their reactivity and catalytic properties. The concentration of different charge states of defects is determined by their formation energies. First-principles calculations are an important tool for computing defect formation energies and for studying the microscopic environment of the defect. The main problem associated with the widely used supercell method in these calculations is the error in the electrostatic energy, which is especially pronou...
Highly Stable, Near-Unity Efficiency Atomically Flat Semiconductor Nanocrystals of CdSe/ZnS Hetero-Nanoplatelets Enabled by ZnS-Shell Hot-Injection Growth
Altintas, Yemliha; Quliyeva, Ulviyya; Gungor, Kivanc; Erdem, Onur; Keleştemur, Yusuf; Mutlugun, Evren; Kovalenko, Maksym V.; Demir, Hilmi Volkan (2019-02-01)
Colloidal semiconductor nanoplatelets (NPLs) offer important benefits in nanocrystal optoelectronics with their unique excitonic properties. For NPLs, colloidal atomic layer deposition (c-ALD) provides the ability to produce their core/shell heterostructures. However, as c-ALD takes place at room temperature, this technique allows for only limited stability and low quantum yield. Here, highly stable, near-unity efficiency CdSe/ZnS NPLs are shown using hot-injection (HI) shell growth performed at 573 K, enab...
Single and multicomponent ion exchange of silver, zinc and copper on zeolite 4a
Ay, Hale; Yücel, Hayrettin; Department of Chemical Engineering (2008)
Ion exchange of heavy metals with zeolites is important in terms of different application areas. Industrial wastewater treatment and antibacterial applications are two essential areas that have taken great attention. While silver, zinc and copper are well known for their toxicity, they are also used as antibacterial agents in zeolites. The objective of this study is to investigate the single and multicomponent ion exchange behavior of zeolite 4A for silver, zinc, copper and sodium ions. For this purpose Ag+...
Addition of Selenium Nanoparticles to Electrospun Silk Scaffold Improves the Mammalian Cell Activity While Reducing Bacterial Growth
Chung, Stanley; Ercan, Batur; Roy, Amit K.; Webster, Thomas J. (2016-07-14)
Silk possesses many beneficial wound healing properties, and electrospun scaffolds are especially applicable for skin applications, due to their smaller interstices and higher surface areas. However, purified silk promotes microbial growth. Selenium nanoparticles have shown excellent antibacterial properties and are a novel antimicrobial chemistry. Here, electrospun silk scaffolds were doped with selenium nanoparticles to impart antibacterial properties to the silk scaffolds. Results showed significantly im...
