A z=5.34 Galaxy Pair in the Hubble Deep Field [PDF]

, 1998
We present spectrograms of the faint V-drop (V(606) = 28.1, I(814) = 25.6) galaxy pair HDF3-951.1 and HDF3-951.2 obtained at the Keck II Telescope. Fernandez-Soto, Lanzetta, & Yahil (1998) derive a photometric redshift of z(ph) = 5.28 (+0.34,-0.41; 2 ...

Combined Photothermal and mTOR‐Targeted Therapy Overcomes Immune Evasion and Enhances Checkpoint Blockade Efficacy in Metastatic Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study reveals that photothermal therapy, while inducing immunogenic cell death in triple‐negative breast cancer, paradoxically activates the oncogenic mTOR pathway to drive immune evasion. To counter this, a smart nanocomposite is engineered to co‐deliver localized hyperthermia and mTOR inhibition.

Phyto‐Confined CeOx with Synergistic Lattice Distortion and Oxygen Vacancies Drives Efficient Urea Electrosynthesis

Advanced Science, EarlyView.
Lattice‐distorted CeOx nanoparticles with abundant oxygen vacancies, confined in porous carbon (d‐CeOx/PC), enable efficient electrocatalytic urea synthesis from CO2 and NO3−. Contracted Ce─O bonds (≈2.29 Å) stabilize OV, creating electron reservoirs for flexible multi‐electron transfer.

Tests of stellar model atmospheres by optical interferometry: VLTI/VINCI limb-darkening measurements of the M4 giant psi phe

, 2003
We present K-band interferometric measurements of the limb-darkened intensity profile of the M4 giant star psi Phoenicis obtained with VLTI/VINCI. High-precision squared visibility amplitudes in the second lobe of the visibility function were obtained ...

Laser Irradiation of Carbonaceous Chondrite Simulants: Space-weathering Implications for C-complex Asteroids

The Planetary Science Journal
Surfaces of carbonaceous asteroids (C-complex) have shown diverse, contrasting spectral variations, which may be related to space weathering. We performed laser irradiation experiments on CI and CM simulant material under vacuum to mimic the spectral ...

Photocatalytically Activated Cu‐N1S3 Single‐Atom Nanozyme: Enhancing Enzyme Activities and Antibacterial Synergy for Highly Efficient Fruit Preservation

Advanced Science, EarlyView.
This study presents S‐coordinated Cu single‐atom nanozymes (Cu/CNS) fabricated via mild photocatalytic self‐assembly strategy. The nanozyme exhibits exceptional multi‐enzyme activity and near‐perfect antimicrobial efficacy. Incorporated into chitosan‐gelatin film, it enables pH‐responsive, broad‐spectrum fruit preservation, more than doubling the shelf‐

Molecular and macromolecular structure changes in polyamide 11 during thermal oxidation [PDF]

, 2014
The present article reports a study of thermal oxidation of unstabilized polyamide 11 films at several temperatures (90–165 °C) under atmospheric pressure and under various oxygen pressures (up to 1.6 MPa) at 110 °C.

Mechanisms of Direct Electron Transfer Governed by Redox‐Active Conductive Carrier with Superior Wettability in Anaerobic Biofilms

Advanced Science, EarlyView.
A redox‐active conductive carrier of tannic acid‐modified iron‐biochar with superior wettability is demonstrated to regulate direct electron transfer at the anaerobic biofilm‐carrier interface by enhancing the cytochrome c‐mediated pathway. For the first time, integrated evidence from spectroscopy, electrochemical analyses, and metatranscriptomics ...

In Situ GISAXS Study of IZO Deposition via Magnetron Sputtering for Optoelectronic Devices: Film Growth and Ion Bombardment‐Induced Degradation Dynamics

Advanced Science, EarlyView.
The dynamics of film growth and ion bombardment‐induced degradation during the film deposition via radio frequency magnetron sputtering of indium zinc oxide are probed with real‐time monitoring via in situ grazing‐incidence small‐angle X‐ray scattering, causing physical degradation on a spin‐coated ZnO NP film and film growth on a robust, commercially ...
