Photometric Redshifts: A New Tool for Studying High-Redshift Clusters [PDF]
arXiv, 1999 We present the first results of our application of photometric redshifts to the study of galaxy populations in high-redshift clusters. For this survey, we are examining a sample of galaxy clusters at z > 0.6 which have already been well-studied in the optical and infrared wavelengths (Oke, Postman & Lubin 1998).

Advanced Materials Interfaces, EarlyView.This study investigates the plasmonic properties and biosensing capabilities of a nanocomposite incorporating Cu and Ag nanoparticles for detecting anti‐DbpA antibodies associated with Lyme disease. The enhanced LSPR response is explained through FDTD simulations of Cu–Ag near‐field interactions and increased surface roughness.

The High-Redshift Gas-Phase Mass–Metallicity Relation in FIRE-2
The Astrophysical Journal LettersThe unprecedented infrared spectroscopic capabilities of JWST have provided high-quality interstellar medium metallicity measurements and enabled characterization of the gas-phase mass–metallicity relation (MZR) for galaxies at z ≳ 5 for the first time ...

Exploring DNA Functionalization Techniques for Silver Nanoparticles
Advanced Materials Interfaces, EarlyView.This study evaluates four functionalization methods—salt‐aging, pH‐assisted, freezing‐directed, and microwave‐assisted—for attaching DNA strands to 20 nm silver nanoparticles (AgNPs). The resulting DNA‐AgNP conjugates are characterized and colloidal stability and DNA loading are assessed.

Is the emission line redshift the redshift? [PDF]
Monthly Notices of the Royal Astronomical Society, 1977 openaire +2 more sources
Advanced Materials Interfaces, EarlyView.A quinone‐functionalized hexaazatriphenylene‐based covalent organic framework (HAQ‐COF) is synthesized, making HAQ‐COF a promising polymer electrolyte membrane material for polymer electrolyte fuel cells. HAQ‐COF exhibits high water retention at room temperature and atmospheric pressure, along with high thermal stability.

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices
Advanced Materials Interfaces, EarlyView.This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.

Dynamical Analysis of the Redshift Drift in FLRW Universes
UniverseRedshift drift is the phenomenon whereby the observed redshift between an emitter and observer comoving with the Hubble flow in an expanding FLRW universe will slowly evolve—on a timescale comparable to the Hubble time.
