Twist and turn: elastohydrodynamics of microscale active fibres
The European Physical Journal Special TopicsAbstractCellular locomotion often involves the motion of thin, elastic filaments, such as cilia and flagella, in viscous environments. The manuscript serves as a general introduction to the topic of modelling microscale elastohydrodynamics. We briefly characterise the specific features of biological filaments that affect their propulsion modes, and ...

Advanced Healthcare Materials, EarlyView.Comparison of therapeutic and diagnostic applications of a surface‐emitting light source with multiwavelength emission characteristics. Abstract Conventional light‐emitting‐diode‐based light sources suffer from rigidity, localized heating, and poor adaptability to skin deformation, limiting their use in skin‐attached medical devices.

Optically active additives in twisted nematic devices
Revue de Physique Appliquée, 1975 A study has been made of the use of optically active additives in twisted nematic devices to remove areas of reverse twist, the results obtained depending on the chirality of the additives and the director alignment on the two containing surfaces. Under certain conditions degeneracy of the field induced reorientation of the director produces a patched ...
