Magnetically Actuated Surface Microstructures for Efficient Transport and Tunable Separation of Droplets and Solids

open access: yesAdvanced Engineering Materials, Volume 25, Issue 22, November 2023., 2023
A novel multifunctional magnetically actuated micro‐lamellar mechatronic platform for efficient transportation of droplets and small solid objects is reported. The propulsion is realized using a four‐pole rotating magnet, resulting in two modes of object transportation: “pushing” mode for precise positioning and “bouncing” mode for heavier solid ...

Oceanic lobate ctenophores possess feeding mechanics similar to the impactful coastal species Mnemiopsis leidyi

open access: yesLimnology and Oceanography, Volume 67, Issue 12, Page 2706-2717, December 2022., 2022
Abstract Lobate ctenophores are often numerically dominant members of oceanic epipelagic and midwater ecosystems. Despite this, little is known about their trophic ecology. Multiple, co‐occurring species are often found in these ecosystems and appear to feed similarly via feeding currents that entrain prey.

Mathematical Modeling of Mucociliary Clearance: A Mini-Review

open access: yesCells, 2019
Mucociliary clearance is an important innate host defense of the mammalian respiratory system, as it traps foreign substances, including pollutants, pathogens, and allergens, and transports them out of the airway.

Fractional Burgers Fluid Flow Due to Metachronal Ciliary Motion in an Inclined Tube

open access: yesFrontiers in Physiology, 2019
Cilia-induced flow of fractional Burgers fluid is studied in an inclined tube for both symplectic and antiplectic wave patterns. The solution of the problem is persued under the long wave length limitation.

Cilia-assisted hydromagnetic pumping of biorheological couple stress fluids

open access: yesPropulsion and Power Research, 2019
A theoretical study is conducted for magnetohydrodynamic pumping of electro-conductive couple stress physiological liquids (e.g. blood) through a two-dimensional ciliated channel. A geometric model is employed for the cilia which are distributed at equal

Pathogenesis of chronic rhinosinusitis with nasal polyps: role of IL-6 in airway epithelial cell dysfunction

open access: yesJournal of Translational Medicine, 2020
Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by an alteration in airway epithelial cell functions including barrier function, wound repair mechanisms, mucociliary clearance.
