Small molecules fail to induce direct reprogramming of adult rat olfactory ensheathing glia to mature neurons

Frontiers in Molecular Neuroscience, 2023
An approach to generate new neurons after central nervous system injury or disease is direct reprogramming of the individual's own somatic cells into differentiated neurons.

Characterizing Conformational Change of a Thermoresponsive Polymeric Nanoparticle with Raman Spectroscopy

Sensors, 2023
Molecular conformational changes in the collapsing and reswelling processes occurring during the phase transition at the lower critical solution temperature (LCST) of the polymer are not well understood. In this study, we characterized the conformational

Froth flotation separation of spodumene ore using (E)-octadec-9-enoylglycine as the flotation collector

Results in Engineering
Effectively separating complexly associated spodumene from calcium-bearing gangue minerals presents significant challenges when using conventional oleate (OA) collectors, primarily due to their limited selectivity and versatility.

Toward a Rational Design of Conjugated Copolymers with Oxygenated Side Chains for Boosting Thermoelectric Properties

Advanced Energy Materials, EarlyView.
The molecular design strategy that integrates both side chain and backbone engineering in diketopyrrolopyrrole‐based conjugated polymers to identify the optimal balance between doping efficiency and microstructural order is demonstrated. Comprehensive spectroscopic, electrochemical, morphological, and structural characterizations reveal that the ...

Globular Aggregates Stemming from the Self-Assembly of an Amphiphilic N-Annulated Perylene Bisimide in Aqueous Media

Nanomaterials, 2021
Herein, we describe the synthesis of highly emissive amphiphilic N-annulated PBI 1 decorated with oligo ethylene glycol (OEG) side chains. These polar side chains allow the straightforward solubility of 1 in solvents of different polarity such as water ...

Supramolecular Assemblies of Self‐Immolative Janus Dendrimers With Rapid Photodegradation Response

Small, EarlyView.
Self‐immolative Janus dendrimers assemble into spherical nanoparticles with solid cores. Upon irradiation, rapid end‐to‐end depolymerization triggers a unique degradation pathway from spheres to crescents within minutes, enabling on‐demand release of encapsulated cargo.
