Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Advanced Materials, EarlyView.This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

Mechanically Programmable DNA Hydrogel Microparticles for 3D Cellular Systems
Advanced Materials, EarlyView.DNA hydrogel microparticles are designed to exhibit controllable viscoelasticity and stiffness across three orders of magnitude from 30Pa$30 \,\mathrm{Pa}$ to 6.5kPa$6.5 \,\mathrm{kPa}$. They are uptaken into fibroblast spheroids where they are actively remodeled by cellular forces depending on their mechanical properties.

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts
Advanced Materials, EarlyView.An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Laser-produced plasmas on Mg, Al and Si surfaces
Fizika A : a journal of experimental and theoretical physics, 2005 Experimental investigations of laser-produced plasmas of Mg, Al and Si are described in this work. Plasmas were produced by nanosecond (6 ns) nitrogen-laser pulses (λ = 337.1 nm) with maximal energy density of about 1.1 J/cm2 and were studied by UV-VIS spectroscopy.

High Charge Carrier Mobility in Non‐Conjugated 3D Covalent Organic Frameworks
Advanced Materials, EarlyView.A non‐conjugated 3D COF constructed via boronate ester linkages from tetraphenylene and pyrene‐based monomers is reported, which exhibits a high charge carrier mobility of 14 ± 1 cm2 V−1 s−1. ABSTRACT π‐Conjugation, π–π stacking, and long‐range order play a central role in determining charge transport efficiency in organic materials.

Ultra‐Confinement of Polaritons in Single Atomic Layer Ag Photonic Quantum Dots
Advanced Materials, EarlyView.Strong confinement of surface phonon polaritons of silicon carbide was achieved in photonic quantum dots fabricated from van der Waals heterostructure of epitaxial graphene over single‐atomic layer silver. Scattering‐type scanning near‐field optical microscopy combined with an analytical approach, developed to reveal local propagation constants with ...
