This study presents guanidinium‐ and indole‐functionalized polyphosphoesters as degradable, non‐viral gene delivery vectors. Through precise tuning of charge density and hydrophobicity, these polymers form stable polyplexes with low toxicity. Remarkably, minor structural changes yield up to 200‐fold differences in transfection efficiency, highlighting ...

Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Spatiotemporally Resolved Orbital Hall Effect in a Topological Semimetal
Real‐space mapping of orbital angular momentum (OAM) transport is achieved using contact‐free polarimetric terahertz spectroscopy. This principle is applied to the topological semimetal Td‐WTe2, revealing the spatial separation of electrons into two distinct regions characterized by opposite out‐of‐plane OAM (±Lz).

Polyphenol‐Mediated Engineering of Lipid Nanoparticles With Crystalline Mesophases
A polyphenol‐mediated strategy enables the one‐step formation of lipid nanoparticles with nonlamellar mesophases, including micellar cubic and hexagonal structures. These highly ordered nanostructures accommodate a wide range of cargos—from metal ions to mRNA—and offer a modular and versatile platform for constructing functional lipid‐based delivery ...

Characterization of Complex Stacking of Semiconductors Through Near Field Imaging and Spectroscopy
SNOM imaging and spectroscopy on a mechanically cleaved facet is used to characterize the different layers of complex epitaxial heterostructures composed of a type II superlattice and highly doped semiconductors. Both the geometrical parameters of the stack and the optical properties of the individual layers and of the interfaces are retrieved, as well

Manipulating Individual Topological Solitons and Bisolitons in an Electronic System
While localized topological modes in quantum materials promise loss‐less delivery of classical and quantum information, manipulating them individually has been challenging. This work succeeded in manipulating topological solitons formed along atomic wires on silicon surfaces with high reproducibility in various ways, including translating, transforming
