Conjugated Copolymers That Shouldn't Be [PDF]

open access: yesAngewandte Chemie International Edition, 2021
AbstractMultiple studies have explored using cage silsesquioxanes (SQs) as backbone elements in hybrid polymers motivated by their well‐defined structures and physical and mechanical properties. As part of this general exploration, we report unexpected photophysical properties of copolymers derived from divinyl double decker (DD) SQs, [vinyl(Me)Si(O0.5)

Co-existing morphologies of lamellae and double arrays of cylinders by A1BA2C tetrablock terpolymer

open access: yesGiant, 2023
Here, we observed, via small-angle X-ray scattering and transmission electron microscopy, co-existing morphologies of lamellae and cylinders by precisely tailoring the volume fraction of each block in polystyrene-b-polyisoprene-b-polystyrene-b-poly(2 ...

Morphological Diversity in Diblock Copolymer Solutions: A Molecular Dynamics Study

open access: yesColloids and Interfaces, 2023
Coarse-grained molecular dynamics simulations that incorporate explicit water-mediated hydrophilic/hydrophobic interactions are employed to track spatiotemporal evolution of diblock copolymer aggregation in initially homogeneous solutions.

Potential Effects of Poloxamer 188 on Rat Isolated Brain Mitochondria after Oxidative Stress In Vivo and In Vitro

open access: yesBrain Sciences, 2021
Outcome after cerebral ischemia is often dismal. Reperfusion adds significantly to the ischemic injury itself. Therefore, new strategies targeting ischemia/reperfusion (I/R) injury are critically needed.

Antifoaming Agent for Lubricating Oil: Preparation, Mechanism and Application

open access: yesMolecules, 2023
In the process of using lubricating oil, it is inevitable that bubbles will be produced, which can not only accelerate the oil’s oxidation and shorten the oil change cycle but also reduce its fluidity and lubricity, aggravate the wear of mechanical parts

Discussion on “Aperiodic Copolymers” [PDF]

open access: yesACS Macro Letters, 2015
In a recent Viewpoint (ACS Macro Lett. 2014, 3, 1020), J.-F. Lutz brought to the community's attention the need for more informative nomenclature, especially with respect to macromolecules with prescribed but not repeating sequences of monomers. Lutz proposes the use of the term "aperiodic" for this situation.
