Controllable Dynamic Mechanical Cell Stimulation using Magnetically Actuated Artificial Cilia

open access: yesAdvanced Healthcare Materials, EarlyView.
This paper introduces a platform based on magnetic artificial cilia for providing controllable dynamic mechanical stimulation to single cells, suitable for investigating large cell populations and enabling live cell imaging. Proof‐of‐principle experiments show that cell morphology is strongly influenced by the artificial cilia, that cellular forces can

Unravelling the Atomic Structure of a Metal‐Covalent Organic Framework Assembled from Ruthenium Metalloligands

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Relaxation phenomena in poly(methyl methacrylate)

open access: yesТонкие химические технологии, 2015
Spectra of internal friction for plasticized and non-plasticized poly(methyl methacrylate) (PMMA) are obtained by dynamic methods of external distortion effect within a frequencies range from 10-2 to 103 Hz and within a temperature range from -50 up to ...

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Additional XPS Studies on the Degradation of Poly(Methyl Methacryalte) and Polystyrene Nanocomposites [PDF]

open access: yes, 2004
XPS studies have been undertaken on exfoliated nanocomposites of polystyrene and poly(methyl methacrylate). One can clearly see that carbon is lost and that oxygen, silicon and aluminum accumulate at the surface of the degrading polymer.
