Advanced Functional Materials, EarlyView.The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene
Advanced Functional Materials, EarlyView.Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

Advanced Functional Materials, EarlyView.Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies
Advanced Functional Materials, EarlyView.The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

The Geometer of Particle Physics
Scientific American, 2006This article profiles French mathematician Alain Connes, focusing on his contribution to mathematics with the development of "noncommutative geometry." This form of geometry places emphasis on the order of events in a sequence, rather than the location of objects. Connes hopes that further research in this field will aid in modelling spacetime.

Time and space are shown to have very different properties, both from each other and from that of the macroscopic world, when they are investigated at distances of the size of elementary particles; even the definition of time is in some doubt in such a case. Space reflection is violated maximally, but time reversal is not.

Particle Physics: A Very Short Introduction
2004Abstract Particle Physics: A Very Short Introduction takes a journey into the atom and presents an overview of the fundamental particles and forces that make up the universe. The VSI discusses the features and functions of particles such as quarks, electrons, and neutrinos, and of gluons and bosons.
