Synthesis of Amylose−Polystyrene Inclusion Complexes by a Facile Preparation Route [PDF]

, 2013
The formation of amylose−polystyrene inclusion complexes via a novel two-step approach is described. In the first-step, styrene was inserted inside the amylose helical cavity, followed by free radical polymerization in the second step.

Flexible Axial Shielding Strategy for Improving Ethylene (Co)polymerization with 8‑Cycloalkylnaphthyl α‑Diimine Catalysts

, 2023
8-aryl or alkyl-naphthyl substituents are widely used as an effective axial shielding strategy for the suppression of chain transfer in late-transition metal-catalyzed ethylene (co)polymerization to yield high molecular weight polyethylene and copolymers.

Exciton Binding Energy of Phosphorescent Emitter Molecules in Organic Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
Energy level alignment is key to efficient OLED design, yet determining LUMO energies remains challenging. A methodology based on field‐induced dissociation and kinetic Monte Carlo simulations is presented to extract LUMO energies of iridium‐based phosphorescent emitters from their exciton binding energy.

Free Radical Emulsion Polymerization of Ethylene

, 2016
Free radical polymerization of ethylene in aqueous media was performed under mild conditions (T ethylene < 250 bar) using an anionic initiating (ammonium persulfate, APS) and stabilizing (sodium dodecyl sulfate, SDS) system, yielding polyethylene latexes.

Near‐Infrared Light‐Driven Zn/Au Janus Micromotors for Multiplex SERS Detection of Anticancer Drugs

Advanced Functional Materials, EarlyView.
Zn/Au Janus micromotors, propelled by thermophoretic effects under NIR light, function as active SERS platforms for single and multiplex detection of anticancer drugs. Their dynamic motion enhances analyte exchange at the Au interface, reducing saturation and competitive adsorption, thereby improving sensitivity and extending the linear detection range.

Backbone‐Controlled Ion‐Side Chain Accessibility in Conjugated Polymers for Organic Electrochemical Synaptic Transistors

Advanced Functional Materials, EarlyView.
Backbone modulation in glycolated conjugated polymers governs ion accessibility to side chains, strengthes anion adsorption, and suppresses back‐diffusion. As the number of thiophene units increases, structural reorganization, retention, and synaptic plasticity are enhanced, leading to improved neuromorphic performance in electrolyte‐gated organic ...

Nutzen und Grenzen der Anwendung kinetischer Modelle für die Reaktorberechnung, dargestellt am Beispiel des Hochdruck-Polyäthylen-Verfahrens

CHIMIA, 1974
The design of a reactor for complex reactions by means of the generally adapted balances of mass, energy and momentum is only possible if the reaction mechanism can be described by a kinetic model.

Spectroscopic Investigation of Polysulfide Redox Evolution in Catholyte Solutions for Potassium–Sulfur Batteries

Advanced Functional Materials, EarlyView.
Potassium–sulfur batteries are investigated using UV–vis spectroscopy to track the evolution of potassium polysulfide species at elevated temperature. The study reveals sulfur radical anions as key intermediates and shows how solvent composition and cell design influence polysulfide stability, redox behavior, and cycling performance, providing insights
