Silicone Nanofilament Support Layers in an Open-Channel System for the Fast Reduction of Para-Nitrophenol [PDF]

open access: yesNanomaterials, 2021
Chemical vapor phase deposition was used to create hydrophobic nanostructured surfaces on glass slides. Subsequently, hydrophilic channels were created by sputtering a metal catalyst on the channels while masking the outside. The surface tension gradient

Impact of Flow in Pipe and Box Coverages on Open Channel’s Performance [PDF]

open access: yesJES: Journal of Engineering Sciences, 2023
This experimental study aims to characterize the behavior of pipe and box coverages concerning their size, form, and upstream blockage ratio. In an artificial trapezoidal cross-section, five experimental cases were carried out: Case 1 involved an ...

Effect of Duration on Variations in Bed Topography and Water Surface Profile in a Meandering Channel [PDF]

open access: yesJournal of Hydraulic Structures, 2021
In this study, variations in water surface profile and bed topography along a meandering path were examined under different experiment durations. Although several studies have been conducted on sediment and scour in open channels, addressing temporal ...

3D numerical simulation of the separation zone at the channel–pipe junction

open access: yesWater Science and Technology, 2023
At the confluence zone, the separation zone affects the flow, pollutant transport, and damages the bed and sidewalls of the channel. In this research, the geometric characteristics of the separation zone and the tailwater effect at the 90° channel–pipe ...

Obtaining High Temperature Stable Sepiolite via Optimization of Acid Treatment Conditions

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2023
Acid treatment of sepiolite under different molarity of HCl at various times was studied to find the best acid treatment conditions for obtaining anhydrous sepiolite without structural folding and with fully open and empty channels.

Feshbach resonances with large background scattering length: interplay with open-channel resonances [PDF]

open access: yes, 2004
Feshbach resonances are commonly described by a single-resonance Feshbach model, and open-channel resonances are not taken into account explicitly. However, an open-channel resonance near threshold limits the range of validity of this model.
