Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 8, Page 505-516, December 2025.
Epithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.

Optimization of Thermally Radiative and Mass Wavy Flow Analysis Affected by Induced Magnetic Field and Joule Heating

open access: yesEnergy Science &Engineering, Volume 13, Issue 10, Page 4917-4932, October 2025.
ABSTRACT The role of magnetic induction is declared fundamental in many technological systems, including electric generators, inductors, transformers, and so on. This is an important source for converting energy from one form to another while utilizing electromagnetic induction. This phenomenon is efficient when the induced magnetic field is introduced

Magnetic Reprogramming of Self‐Assembled Hard‐Magnetic Cilia

open access: yesAdvanced Materials Technologies, Volume 9, Issue 13, July 8, 2024.
Hard‐magnetic cilia form through self‐assembly of NdFeB microparticles within a thermoplastic polyurethane elastomer. NdFeB cilia can be remagnetized, which reprograms their actuation behaviors. Performing demagnetization prior to remagnetization improves the reprogrammability of the cilia.

Light‐Fueled Nonreciprocal Self‐Oscillators for Fluidic Transportation and Coupling

open access: yesAdvanced Materials, Volume 36, Issue 12, March 21, 2024.
Non‐equilibrium self‐sustained motions are widely reported in stimuli‐responsive material systems. Here, a cilia‐like soft actuator that can perform self‐sustained oscillation under water, with programmable nonreciprocal strokes, is demonstrated. The self‐oscillators can realize microfluidic pumping, translocation of a micro‐object, and coupling ...
