Small Structures, Volume 5, Issue 7, July 2024.Cellulose nanocrystals are abundant, biodegradable nanoparticles that can self‐assemble into a helical stacking that exhibits structural color. By adding a single surfactant, cellulose nanocrystals can be made compatible with apolar solvents, which are widely used for industrial coatings.

CONSTRAINTS ON PHOTOIONIZATION FEEDBACK FROM NUMBER COUNTS OF ULTRA-FAINT HIGH-REDSHIFT GALAXIES IN THE FRONTIER FIELDS [PDF]
, 2014 We exploit a sample of ultra-faint high-redshift galaxies (demagnified Hubble Space Telescope, HST, H160 magnitude > 30) in the Frontier Fields clusters A2744 and M0416 to constrain a theoretical model for the UV luminosity function in the presence of ...

Small Structures, Volume 5, Issue 4, April 2024.An ultrasensitive and visible detection for influenza A virus is presented by leveraging the properties of gold nanoparticles (GNPs). Dual amplification, achieved through a synthetic nanoprobe utilizing the enzymatic properties of layered GNPs, exhibits a higher sensitivity. This system is suitable for point‐of‐care tests within 55 min by verifying its

Evolution of Nonparametric Morphology of Galaxies in the JWST CEERS Field at z ≃ 0.8–3.0
The Astrophysical Journal, 2023 Galaxy morphology is one of the most fundamental ways to describe galaxy properties, but the morphology we observe may be affected by wavelength and spatial resolution, which may introduce systematic bias when comparing galaxies at different redshift ...

THERMAL AND RADIATIVE ACTIVE GALACTIC NUCLEUS FEEDBACK HAVE A LIMITED IMPACT ON STAR FORMATION IN HIGH-REDSHIFT GALAXIES [PDF]
, 2014 The effects of active galactic nuclei (AGNs) on their host galaxies depend on the coupling between the injected energy and the interstellar medium (ISM). Here, we model and quantify the impact of long-range AGN ionizing radiation—in addition to the often

Chemical Evolution of the Universe and its Consequences for Gravitational‐Wave Astrophysics
Annalen der Physik, Volume 536, Issue 2, February 2024.Population properties of double compact object mergers (especially binary black holes) are sensitive to the metallicity dependent cosmic star formation history. The uncertainty of this quantity cannot be ignored and makes the interpretation of current gravitational wave observations difficult.

ACCOUNTING FOR COSMIC VARIANCE IN STUDIES OF GRAVITATIONALLY LENSED HIGH-REDSHIFT GALAXIES IN THE HUBBLE FRONTIER FIELD CLUSTERS [PDF]
, 2014 Strong gravitational lensing provides a powerful means for studying faint galaxies in the distant universe. By magnifying the apparent brightness of background sources, massive clusters enable the detection of galaxies fainter than the usual sensitivity ...
