Dimensional Engineering of Carbon‐Based Hybrids: From 1D Conductive Networks to 3D Porous Architectures for Next‐Generation Microwave Absorption

Advanced Science, EarlyView.
This review explores dimensional architecture engineering to overcome the impedance‐attenuation trade‐off in electromagnetic wave absorbing materials. By analyzing 1D to 3D structures and their multidimensional hybrids, we highlight synergistic mechanisms for enhanced performance.

Massive star clusters detected by JWST as natural birthplaces of intermediate-mass black holes

Astronomy & Astrophysics
The James Webb Space Telescope (JWST) has detected, through gravitational lensing, several young massive star clusters (YMCs), which are considered as relevant building blocks of high-redshift galaxies. In this work, we show how a significant fraction of

Clusters, Clumps, Dust, and Gas (CCDG) in NGC 1614: Benchmarking Cluster Demographics in Extreme Systems

The Astronomical Journal
Observations of young star clusters in a variety of galaxies have been used to constrain basic properties related to star formation, such as the fraction of stars found in clusters (Γ) and the shape of the cluster mass function (CMF).

A Microenvironment‐Adaptive Scaffold Rejuvenates Peripheral Nerve Regeneration During Aging Via Dual Modulation of Ferroptotic Stimuli in Schwann Cells

Advanced Science, EarlyView.
(i) Aging impairs peripheral nerve regeneration via its dual ferroptosis‐mediated pathologies in senescent schwann cells. (ii) The composite nerve conduit is a symbiosis niche integrating microenvironment‐responsive nanoparticles (Ga‐PTAs) and maxillofacial‐derived mesenchymal stem cells (Mmscs).

Young Massive Clusters – Formation Efficiencies and (Initial) Mass Functions [PDF]

, 2008
Globular clusters are often assumed to be good tracers of major star formation episodes in their host galaxies. While observations over the past 2 decades have confirmed the presence of young objects with globular cluster-like properties in many galaxies, it is still not well understood exactly how the formation efficiency of bound star clusters ...
