Structure and Intermolecular Interactions between L-Type Straight Flagellar Filaments. [PDF]

open access: yes, 2017
Bacterial mobility is powered by rotation of helical flagellar filaments driven by rotary motors. Flagellin isolated from the Salmonella Typhimurium SJW1660 strain, which differs by a point mutation from the wild-type strain, assembles into straight ...

Instability of Myelin Tubes under Dehydration: deswelling of layered cylindrical structures

open access: yes, 2001
We report experimental observations of an undulational instability of myelin figures. Motivated by this, we examine theoretically the deformation and possible instability of concentric, cylindrical, multi-lamellar membrane structures. Under conditions of

Hydrogel Thermostat Inspired by Photoprotective Foliage Using Latent and Radiative Heat Control

open access: yesAdvanced Materials, EarlyView.
Guided by Populus alba foliage, this hydrogel latent‐radiative thermostat (LRT) actively balances latent and radiative heat fluxes. An LRT switches solar reflectance, maintains high mid‐IR emissivity, and reversibly evaporates/regenerates water, while titanium oxide (TiO2) nanoparticles toughen the film.

Electrically Tunable Friction: From Sticky to Slippery with Ionic Hydrogels

open access: yesAdvanced Materials, EarlyView.
This work demonstrates electrically tunable friction “from sticky to slippery” using ionic hydrogels, achieving reversible more‐than‐fifty‐fold modulation without liquid lubricants. An electric field extracts a salt‐rich interfacial layer that dramatically reduces friction.

Cancer Cells Traverse Faster in Confined Space by Modifying Vimentin filaments With Nuclear Deformation and Promoting the Growth of Desired Tumor Spheroids

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates how the Vimentin intermediate (VIM) filaments distribution/density regulates the attainment of different migration modes through cytoskeleton rearrangement and controls the nuclear morphology in migrating cells under physical confinement, which facilitates the faster traversing of those cells and the growth of post‐migration ...
