Fluorine atom substituted aromatic polyimides: Unlocking extraordinary dielectric performance and comprehensive advantages

Giant
Low-dielectric polymers face prominent development challenges at high frequency. Particularly, the relationship between the high-frequency dielectric loss and polymer structures remains not clear enough.

Sequential self-assembly of DNA functionalized droplets

Nature Communications, 2017
Natural complex systems are often constructed by sequential assembly but this is not readily available for synthetic systems. Here, the authors program the sequential self-assembly of DNA functionalized emulsions by altering the DNA grafted strands.

Dynamic light scattering for particle characterization subjected to ultrasound: a study on compact particles and acousto-responsive microgels

Scientific Reports
In this report, we investigate dynamic light scattering (DLS) from both randomly diffusing silica particles and acousto-responsive microgels in aqueous dispersions under ultrasonic vibration.

Elastin-like polypeptide coacervates as reversibly triggerable compartments for synthetic cells

Communications Chemistry
Compartmentalization is a vital aspect of living cells to orchestrate intracellular processes. In a similar vein, constructing dynamic and responsive sub-compartments is key to synthetic cell engineering.

Two energy barriers and a transient intermediate state determine the unfolding and folding dynamics of cold shock protein

Communications Chemistry, 2021
Force-dependent transitions can provide insights into the free-energy landscape of proteins. Here, the authors observe the folding and unfolding dynamics of the model protein Csp using magnetic tweezers, from which a free-energy landscape with two energy
