Interlayer Expansion of Bulk MoS2 via Top‐Down Organic Pillaring Enables Tunable Li+ Intercalation and Controlled Solvent Co‐Intercalation

Advanced Functional Materials, EarlyView.
Top‐down organic pillaring expands the interlayer spacing of bulk‐sized MoS2 particles while preserving the bulk morphology. Operando X‐ray diffraction and electrochemical dilatometry show that MoS2‐bulk undergoes solvent co‐intercalation in diglyme electrolyte, causing large structural expansion, while pillared, expanded MoS2 suppresses solvent uptake

Collapse of Rotating Very Massive Stellar Cores Leading to a Black Hole and a Massive Disk as a Source of Gravitational Waves

The Astrophysical Journal
We derive models of rotating very massive stellar cores with mass ≈10 ^2 –10 ^4 M _⊙ that are marginally stable to the pair-unstable collapse, assuming that the core is isentropic and composed primarily of oxygen.

Double‐Interpenetrating Composite Bioink for Multi‐Component 3D Bioprinting and Biofabrication

Advanced Functional Materials, EarlyView.
Marine‐polysaccharides‐derived double interpenetrating network hydrogel‐based bioink, combining the attributes of physical and ionic crosslinking, enables room‐temperature bioprinting of mechanically defined structures that can be handled and are cytocompatible.

GW231123: Likely a Product of Successive Mergers from ∼10 Stellar-mass Black Holes

The Astrophysical Journal
GW231123 is an exceptionally massive binary black hole (BBH) merger with unusually high component spins. Such extreme properties challenge conventional stellar evolution models, predicting a black hole (BH) mass gap due to pair-instability supernovae. We

Packed for Ossification: High‐Density Bioprinting of hPDC Spheroids in HAMA Toward Endochondral Ossification

Advanced Healthcare Materials, EarlyView.
Human periosteum‐derived cell spheroids bioprinted at high density within a hyaluronic acid matrix promote fusion and hypertrophic cartilage formation in vitro. Early encapsulation enhances spheroid interaction and matrix maturation, generating scalable cartilage templates intended for endochondral bone regeneration.

Formation of Sub-Chandrasekhar-mass Black Holes and Red Stragglers via Hawking Stars in Ultrafaint Dwarf Galaxies

The Astrophysical Journal
Primordial black holes (PBHs) in the asteroid mass window from 10 ^−16 M _⊙ to 10 ^−10 M _⊙ are currently a popular dark matter candidate. If they exist, some stars would capture them upon formation, and they would slowly accrete the star over gigayears.

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

Advanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Stellar-mass black holes on the millimetre Fundamental Plane of black hole accretion

Monthly Notices of the Royal Astronomical Society
ABSTRACT Recent work revealed the existence of a galaxy ‘millimetre Fundamental Plane of black hole accretion’, a tight correlation between nuclear 1 mm luminosity, intrinsic 2–10 keV X-ray luminosity and supermassive black hole mass, originally discovered for nearby low- and high-luminosity active galactic nuclei.

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
