Ratiometric nanothermometer in vivo based on triplet sensitized upconversion
Nature Communications, 2018 Though luminescence imaging is a promising approach for contactless thermometry in vivo, the low thermal sensitivity of existing thermometers limits its potential.

Geminate labels programmed by two-tone microdroplets combining structural and fluorescent color
Nature Communications, 2021 Creating an enhanced-security-level label that carries entirely distinct information in different optical states has proven challenging. Here, the authors design geminate labels by programming fluorescent cholesteric liquid crystal microdroplets to ...

Conformational landscape of long semiflexible linear and ring polymers near attractive surfaces [PDF]
arXiv, 2023 Conformations of a crowded neutral semiflexible polymer under confinement near an attractive wall are studied via coarse-grained simulations. We study the effects of the interplay of the length of the polymer, bending rigidity, and the repulsive crowder density on such equilibrium semiflexible polymer conformations.

Polymer scission in turbulent flows [PDF]
J. Fluid Mech. 912 (2021) A18, 2020 Polymers in a turbulent flow are subject to intense strain, which can cause their scission and thereby limit the experimental study and application of phenomena such as turbulent drag reduction and elastic turbulence. In this paper, we study polymer scission in homogeneous isotropic turbulence, through a combination of stochastic modelling, based on a ...

Nano-Micro Letters, 2022 The anode-free design is a promising strategy to increase the energy density of aqueous Zn metal batteries (AZMBs). However, the scarcity of Zn-rich cathodes and the rapid loss of limited Zn greatly hinder their commercial applications.

Environmentally Friendly Polymers and Polymer Composites [PDF]
Materials, 2020 In the last decade, continuous research advances have been observed in the field of environmentally friendly polymers and polymer composites due to the dependence of polymers on fossil fuels and the sustainability issues related to plastic wastes. This research activity has become much more intense in the food packaging industry due to the high volume ...

Influence of Solvent Quality on Conformations of Crowded Polymers [PDF]
J. Chem. Phys. 149, 124901 (2018), 2018 The structure and function of polymers in confined environments, e.g., biopolymers in the cytoplasm of a cell, are strongly affected by macromolecular crowding. To explore the influence of solvent quality on conformations of crowded polymers, we model polymers as penetrable ellipsoids, whose shape fluctuations are governed by the statistics of self ...
