Imaging Ionic Displacements Across Inclined Ferroelectric Domains by a Reciprocity Approach to 4D‐STEM

Small, EarlyView.
Four‐dimensional STEM comprises a vast portfolio of electron microscopy methods in one data set, conventional plane‐wave illumination TEM being one of them. Here, the principle of reciprocity is employed to produce true structural projections of misoriented ferroelectric domains at atomic resolution. By reciprocal TEM imaging from four‐dimensional STEM

HS‐AFM Reveals Hierarchical RNA Folding Driving Condensate Assembly and Material States

Small, EarlyView.
High‐speed atomic force microscopy reveals the nanoscale pathway of RNA condensate formation, from individual RNA folding to higher‐order assembly. Quantitative analyses of fusion dynamics and nanomechanical properties distinguish liquid‐like poly A condensates from solid‐like total RNA assemblies, providing a direct link between RNA self‐assembly and ...

Revealing Airflow–Particle Dynamics in Dry Powder Inhalers

Small, EarlyView.
An integrated framework combining device and formulation characterization, CFD–DEM simulations, and interpretable machine learning is established. This framework reveals how airflow and particle interactions govern powder dispersion across prevailing dry powder inhalers.

Vat Polymerization 3D Printing of Hydrogels With Tunable Porosity

Small Methods, EarlyView.
Nanodroplet emulsion templating enables DLP printing of porous hydrogels with pore sizes tunable across two orders of magnitude, from 46.15 to 0.66 µm. The printed interconnected networks retain high fidelity while improving mechanical robustness and cellular responses, providing a versatile platform for porous hydrogel biofabrication.
