Core/shell magnetite/copolymer composite nanoparticles enabling highly stable magnetorheological response

open access: yesInternational Journal of Mechanical System Dynamics, 2022
Magnetorheological fluids (MRFs) have been successfully used in a variety of smart control systems, but are still limited due to their relatively poor settling stability.

Electrostatically gated membrane permeability in inorganic protocells [PDF]

open access: yes, 2013
Although several strategies are now available to produce functional microcompartments analogous to primitive cell-like structures, little progress has been made in generating protocell constructs with self-controlled membrane permeability.

Application of Self-Assembled Polyarylether Substrate in Flexible Organic Light-Emitting Diodes

open access: yesMicromachines, 2023
The structure used in this study is as follows: substrate/PMMA/ZnS/Ag/MoO3/NPB/Alq3/LiF/Al. Here, PMMA serves as the surface flattening layer, ZnS/Ag/MoO3 as the anode, NPB as the hole injection layer, Alq3 as the emitting layer, LiF as the electron ...

Aperiodic Copolymers

open access: yesACS Macro Letters, 2014
Current polymer terminology only describes very simple copolymer structures such as block, graft, alternating periodic, or statistical copolymers. This restricted vocabulary implies that copolymers exhibit either segregated (i.e., block and graft), regular (i.e., alternating and periodic), or uncontrolled (i.e., statistical or random) comonomer ...

Exploring Class I polyhydroxyalkanoate synthases with broad substrate specificity for polymerization of structurally diverse monomer units

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
Polyhydroxyalkanoate (PHA) synthases (PhaCs) are key enzymes in PHA polymerization. PhaCs with broad substrate specificity are attractive for synthesizing structurally diverse PHAs.
