Interfacial Yield Stress Response in Synthetic Mucin Solutions

Advanced Materials Interfaces, EarlyView.
The solution rheology of novel synthetic mucins mimicking natural mucin domains is studied. Like many natural mucin solutions, apparent solid‐like rheology is seen. However, no bulk structural features are found to explain it. Interfacial rheology and robust modelling reveal that this arises from molecular associations at the air–water interface ...

Optical Nanotweezers Based on All-Dielectric Resonant Structures

Advanced Devices & Instrumentation
Optical tweezers are a valuable tool for manipulating micro- and nano-objects due to their noncontact and nondestructive nature. These features render them highly valuable for applications such as biological detection and precision measurement.

Measuring storage and loss moduli using optical tweezers: broadband microrheology

, 2009
We present an experimental procedure to perform broadband microrheological measurements with optical tweezers. A generalised Langevin equation is adopted to relate the time-dependent trajectory of a particle in an imposed flow to the frequency-dependent ...

Manipulating rod-shaped bacteria with optical tweezers

Scientific Reports, 2019
Optical tweezers have great potential in microbiology for holding and manipulating single cells under a microscope. However, the methodology to use optical tweezers for live cell studies is still at its infancy.

Effective Manipulation of Water Droplets on Open Superhydrophobic Glass Surfaces by Using a Triboelectrically Charged Polytetrafluoroethylene Rod on the Back Side of These Surfaces

Advanced Materials Interfaces, EarlyView.
The movement of pure water droplets on a superhydrophobic glass surface is precisely controlled through electrostatic manipulation using a polytetrafluoroethylene (PTFE) rod from the opposite side. With just a few seconds of triboelectric charging, the PTFE rod directs droplets, achieving acceleration over 10 000 mm s−2.

Improvement of Electrochromic Stability of Viologen‐Based Ionic Gel by Layered Metal–Organic Frameworks

Advanced Materials Interfaces, EarlyView.
Metal–organic framework doped viologen‐based ionogel electrochromic device demonstrates superior performance including homogeneous chromatic transition, enhanced coloration efficiency, and exceptional cycling stability. These advancements originate from dual mechanisms: 1) physical confinement effect effectively suppressing viologen molecular ...

Theoretical and Experimental Investigation of the Ligand‐Directed Assembly and Photovoltaic Performance of PbSe Nanorods

Advanced Materials Interfaces, EarlyView.
This study delves into the critical role of ligand type on morphology, photophysical behavior, and optoelectronic performance of PbSe Nanorods (NRs). A combination of computational modelling and experimental techniques reveals that EDT‐capped PbSe NRs exhibit well‐ordered packing with strong interfacial coupling and improved optoelectronic performance.
