Relaxation dynamics in a transient network fluid with competing gel and glass phases

open access: yes, 2015
We use computer simulations to study the relaxation dynamics of a model for oil-in-water microemulsion droplets linked with telechelic polymers. This system exhibits both gel and glass phases and we show that the competition between these two arrest ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Effect of Alkyl Side Chain Length on the Lithium-Ion Conductivity for Polyether Electrolytes

open access: yesFrontiers in Chemistry, 2022
The design guidelines of polymer structure to effectively promote lithium-ion conduction within the polymer electrolytes (PEs) are crucial for its practical use.

Two-Dimensional Controlled Syntheses of Polypeptide Molecular Brushes via N-Carboxyanhydride Ring-Opening Polymerization and Ring-Opening Metathesis Polymerization. [PDF]

open access: yes, 2017
Well-defined molecular brushes bearing polypeptides as side chains were prepared by a "grafting through" synthetic strategy with two-dimensional control over the brush molecular architectures.

Steric Hindrance in Metal Coordination Drives the Separation of Pyridine Regioisomers Using Rhodium(II)-Based Metal-Organic Polyhedra.

open access: yesAngewandte Chemie, 2021
The physicochemical similarity of isomers makes their chemical separation through conventional techniques energy intensive. Herein, we report that, instead of using traditional encapsulation-driven processes, steric hindrance in metal coordination on the

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Gas-Phase Construction of Compact Capping Layers for High-Performance Halide Perovskite X-Ray Detectors

open access: yesNano-Micro Letters
Highlights A gas-phase method has been developed, which can directly grow two-dimensional perovskite on three-dimensional perovskite with nanoscale precision. The steric hindrance of the organic layer within 2D perovskites influences the ion migration in

Catalytic enantioselective construction of axial chirality in 1,3-disubstituted allenes

open access: yesNature Communications, 2019
Highly enantioselective synthesis of allenes has been relying, so far, on the steric hindrance of substrates. Here the authors achieve excellent stereocontrol in the synthesis of chiral allenes with a palladium-DTBM-SEGPHOS catalytic system in a non ...

Crystallinity and phase separation induced morphological modulation for efficient ternary all-polymer solar cells

open access: yesAPL Energy, 2023
All-polymer solar cells (all-PSCs) have attracted enormous attention and achieved significant progress in recent years due to their long-term stability and excellent film stretchability.

RNA polymerase interactions and elongation rate

open access: yes, 2018
We show that non-steric molecular interactions between RNA polymerase (RNAP) motors that move simultaneously on the same DNA track determine strongly the kinetics of transcription elongation.
