Flexible modeling and dynamics simulation of four-bar beating-up system with clearance

Journal of Industrial Textiles, 2023
To explore the actual working characteristic of the beating-up mechanism on looms, the Step function is adopted to convert the beating-up resistance to an equivalent torque acting on the rocking shaft, and a new method of calculating and simulating the ...

Towards vibrational spectroscopy on surface-attached colloids performed with a quartz crystal microbalance

Sensing and Bio-Sensing Research, 2016
Colloidal spheres attached to a quartz crystal microbalance (QCM) produce the so-called “coupled resonances”. They are resonators of their own, characterized by a particle resonance frequency, a resonance bandwidth, and a modal mass.

Tuning Separator Chemistry: Improving Zn Anode Compatibility via Functionalized Chitin Nanofibers

Advanced Functional Materials, EarlyView.
Nanochitin derived from waste shrimp shells is used to fabricate separators for aqueous zinc batteries. By tuning the density of amine and carboxylic surface groups, water mobility at the separator interface is controlled, promoting uniform zinc deposition, suppressing dendrite growth, and enabling exceptional cycling stability exceeding 2000 h ...

Respiratory entrainment of the locus coeruleus modulates arousal level to avoid physical risks from external vibration

Scientific Reports, 2023
Slow rocking chairs can easily put people to sleep, while violent shaking, such as during earthquakes, may lead to rapid awakening. However, the influence of external body vibrations on arousal remains unclear.
