Selective elimination of quiescent cancer cells by dequalinium chloride via ROS‐mediated ferroptosis

FEBS Open Bio, EarlyView.
Dequalinium chloride (DQ) selectively eliminates quiescent cancer cells (QCCs) by amplifying mitochondrial ROS. QCCs exhibit elevated basal ROS and limited redox‐buffering capacity, making them vulnerable to further ROS increases. DQ‐induced ROS exceeds the tolerance threshold, triggering lipid peroxidation and ferroptosis, whereas proliferating cells ...

THE REACTION OF POLYSTYRENES WITH BROMINE

, 1940
The quantitative determination of the absorption by polystyrenes of oxygen from benzoyl hydrogen peroxide yields low results in all cases. The action of bromine on polystyrenes is a function of the concentration. With relatively higher concentrations of

Using fluorescence fluctuation spectroscopy to quantify molecular dynamics within cells

FEBS Open Bio, EarlyView.
Microscopy techniques like fluorescence correlation spectroscopy (FCS) and number and brightness analysis (N&B) allow to quantify concentrations, diffusion rates, and oligomerization of fluorescently labeled molecules in the living cell. In this protocol the principles of how to set up these types of experiments are described including calibration ...

High triplet energy electron transport side-chain polystyrenes containing dimesitylboron and tetraphenylsilane for solution processed OLEDs

, 2017
A series of polystyrenes was developed as electron transport materials (ETMs) for solution processed organic light emitting diodes (OLEDs), containing dimesitylboryl (BMes2) and tetraphenylsilanyl in their side-chains.

Surface modification of 3D‐printed polycaprolactone scaffolds with silk fibroin for bone tissue engineering

FEBS Open Bio, EarlyView.
Coating 3D‐printed PCL scaffolds with silk fibroin can improve biocompatibility and bone cell adhesion. One innovative design for tissue‐engineering scaffolds uses 3D printing technology. Here, we used polycaprolactone (PCL) filament as a biocompatible material to design a porous 3D scaffold for bone tissue engineering.

Recycled Polystyrene Waste to Triboelectric Nanogenerators: Volumetric Electromechanically Responsive Laminates from Same‐Material Contact Electrification

Advanced Energy & Sustainability Research
Millions of tonnes of polystyrene (PS) are produced annually, with only an estimated 12% being recycled. Herein, the upcycling of expanded or foamed PS waste into electromechanically responsive triboelectric laminates (TLs) is described.

Polystyrene grafted onto high-cis-1,4 polybutadiene backbone via 'living' radical polymerization with 2,2,6,6-tetramethylpiperidinyl-1-oxy (TEMPO) radical

eXPRESS Polymer Letters, 2011
A stable nitroxide radical (2,2,6,6-tetramethylpiperidinyl-1-oxy, TEMPO) was employed to a grafting polymerization of styrene onto the high-cis-1,4 polybutadiene (PB) rubber initiated by 1,1-bis(tert-butylperoxy)cyclohexane (DP275B).

Adjusting Nucleation Chemistry for the Atomic Layer Deposition of Antimony Selenide on Metal Oxide Surfaces

Advanced Engineering Materials, EarlyView.
The ALD precursor bis(trimethylsilyl)selenide is simultaneously a substrate surface inhibitor. It allows for the growth of Sb2Se3 in combination with tris(dimethylamido)antimony, but also silylates surface hydroxyl groups on the substrate if such hydroxyls are present.
