Concept of Recycling‐on‐Demand Investigated on Linear Poly(Ester‐Co‐Acetal)s

open access: yesMacromolecular Materials and Engineering
Effective recycling of polymers into valuable resources is the basis for establishing a circular economy. Whereas mechanical recycling often leads to downcycling, the concept of recycling‐on‐demand (ROD) has high promise.

Effective Regulation of Polycaprolactone Molecular Weight and Oligomers Content Using Tetraphenyltin Catalyst [PDF]

open access: yes, 2020
There is a lack of effective approaches that produce polycaprolactone materials (PCL) with a high molecular weight, narrow polymer dispersity index (PDI), and fewer formation of oligomers.

Characterizing Cutaneous α‐Synuclein Deposition and Seeding Activity in Parkinson's Disease Subtypes

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cutaneous phosphorylated α‐synuclein (p‐syn) and α‐synuclein seeding activity are promising biomarkers for Parkinson's disease (PD), but their clinical value remains uncertain due to disease heterogeneity. This study evaluates these two biomarkers in PD patients to inform phenotype‐specific diagnosis and disease severity assessment ...

Perylenediimide‐Siloxane Block Molecules Displaying Circularly Polarized Emission from Achiral Nanostructured Surfaces

open access: yesChemistryEurope
The development of organic dyes is crucial for high‐tech technologies such as displays, telecommunication, and anticounterfeiting. While rylene diimides such as naphthalene and perylene diimides (NDIs and PDIs) exhibit promising optical properties, their

Phenylethynyl terminated imide oligomers [PDF]

open access: yes, 1994
Four phenylethynyl amine compounds - 3 and 4-aminophenoxy-4'-phenylethynylbenzophenone, and 3 and 4-amino-4'-phenylethynylbenzophenone - were readily prepared and were used to endcap imide oligomers.

Amyloid β-protein oligomers and Alzheimer’s disease [PDF]

open access: yes, 2013
The oligomer cascade hypothesis, which states that oligomers are the initiating pathologic agents in Alzheimer's disease, has all but supplanted the amyloid cascade hypothesis, which suggested that fibers were the key etiologic agents in Alzheimer's ...

Kinetics‐Controlled Architecture of Binder‐Free Organic Electrodes for Enhanced Ion Transport

open access: yesAdvanced Functional Materials, EarlyView.
Pulse reverse electrodeposition controls nucleation and growth to create hierarchically porous Py‐derived oligomeric electrodes with enhanced ionic accessibility and reduced transport resistance. The resulting binder‐free architectures translate these transport advantages into practical sodium‐storage functionality.
