Comparing the relative influence of obesity and ancestry on timing of dental development.

Introduction: The dentition is one of the most accurate features for age estimation in children. However, there is some evidence that timing of dental development varies across populations. Recent research suggests that dental development may also be susceptible to influence by environmental factors, such as obesity.

Ferrocene containing redox-responsive poly(2-oxazoline)s.

A new monomer, 2-ferrocene-ethyl-2-oxazoline, was copolymerized with 2-alkyl-2-oxazolines. The cationic ring opening polymerization (CROP) of 2-oxazolines allows the synthesis of well-defined copolymers with adjustable molar masses as well as end-group control, which was also evident from kinetic studies. The utilization of this new comonomer led to redox-active polymers as proven by UV-VIS-measurements and cyclic-voltammetry.

Emulsion Polymerizations for a Sustainable Preparation of Efficient TEMPO-based Electrodes.

Organic polymer-based batteries represent a promising alternative to present-day metal-based systems and a valuable step toward printable and customizable energy storage devices. However, most scientific work is focussed on the development of new redox-active organic materials, while straightforward manufacturing and sustainable materials and production will be a necessary key for the transformation to mass market applications. Here, a new synthetic approach for 2,2,6,6-tetramethyl-4-piperinidyl-N-oxyl (TEMPO)-based polymer particles by emulsion polymerization and their electrochemical investigation are reported.

One-Pot Synthesis of Block Copolymers by a Combination of Living Cationic and Controlled Radical Polymerization.

The reversible addition-fragmentation chain-transfer (RAFT) process represents a sophisticated polymerization technique for the preparation of tailored and well-defined polymers from acrylates, acrylamides, and (meth)acrylates. The direct switching from other methods, such as cationic polymerizations, without the need for tedious functionalization and purification steps remains challenging. Within this study, it is demonstrated that poly(2-oxazoline) (P(Ox)) macro chain-transfer agents (macro-CTAs) can be prepared through the quenching of the cationic ring-opening polymerization with a carbonotrithioate salt.
