Transient Stiffness Patterning in Hydrogels Driven by Dissipative Mechanochemical Coupling

Advanced Functional Materials, EarlyView.
Force‐induced disulfide bond rupture in a polymer‐based hydrogel, coupled with chemical or electrochemical reoxidation, leads to the transient modulation of the hydrogel's stiffness properties. High spatiotemporal control is achieved by this dissipative process, enabling the development of out‐of‐equilibrium stiffness patterns and transient, dose ...

Optical Continuum Reverberation Mapping of a Candidate IMBH in a Nearby Seyfert 1 Galaxy

The Astrophysical Journal
To investigate the short-term variability and determine the size of the optical continuum emitting region of intermediate-mass black holes (IMBHs), we carried out high-cadence, multiband photometric monitoring of a Seyfert 1 galaxy J0249−0815 across two ...

Binary Intermediate-mass Black Hole Mergers in Globular Clusters [PDF]

Astrophysical Journal, 2019
We consider the formation of binary intermediate black holes (BIMBHs) in globular clusters (GC), which could happen either in situ or due to the mergers between clusters.

Plasma‐Treated Hydrogel for Combined RONS and Chemotherapy Delivery: A Proof‐of‐Concept In Ovo

Advanced Functional Materials, EarlyView.
This study explores plasma‐treated hydrogels (PTH) as a new way to deliver both reactive oxygen and nitrogen species and chemotherapy (Doxorubicin) directly to tumors. In ovo tests show effects after a single dose, especially in osteosarcoma tumors. Tumor weight decrease, and a resistance‐related protein is reduced.

Constraints on metric-Palatini gravity from QPO data

European Physical Journal C: Particles and Fields
In this work, we study metric-Palatini gravity extended by the antisymmetric part of the affine curvature. This gravity theory leads to general relativity plus a geometric Proca field.

X-ray study of HLX1: intermediate-mass black hole or foreground neutron star? [PDF]

, 2010
We re-assess the XMM-Newton and Swift observations of HLX1, to examine the evidence for its identification as an intermediate-mass black hole. We show that the X-ray spectral and timing properties are equally consistent with an intermediate-mass black ...

Achieving Chemical Recognition, Recycling, and Circularity With Radical Nanostructures

Advanced Functional Materials, EarlyView.
Here, innovative 3D radical nanostructures based on 4,4′‐dicyano‐2,2′‐biphenylene‐fused tetrazolinyl radical, fabricated on interdigitated gold‐SiO2 hybrid surfaces are presented. They retain their magnetic properties, their morphology and size can can tune, selectively remove them from specific substrate regions using distilled water, and return the ...

DAVOS: Dwarf Active Galactic Nuclei from Variability for the Origins of Seeds: Properties of Variability-selected Active Galactic Nuclei in the COSMOS Field and Expectations for the Rubin Observatory

The Astrophysical Journal
We study the black hole mass–host galaxy stellar mass relation, M _BH – M _* , of a sample of z < 4 optically variable active galactic nuclei (AGNs) in the COSMOS field. The parent sample of 491 COSMOS AGNs were identified by optical variability from the

Gravitational Radiation from Intermediate‐Mass Black Holes [PDF]

The Astrophysical Journal, 2002
Recent X-ray observations of galaxies with ROSAT, ASCA, and Chandra have revealed numerous bright off-center point sources which, if isotropic emitters, are likely to be intermediate-mass black holes, with hundreds to thousands of solar masses. The origin of these objects is under debate, but observations suggest that a significant number of them ...
