Co‐Delivery of Ca‐MOF and Mg‐MOF Using Nanoengineered Hydrogels to Promote In Situ Mineralization and Bone Defect Repair: In Vitro and In Vivo Analysis

Advanced Healthcare Materials, EarlyView.
Metal‐organic frameworks (MOFs) have been synthesized using calcium (Ca‐MOF), magnesium (Mg‐MOF), and as hybrids (Ca/Mg‐MOF) for bone healing applications. MOFs are integrated into hydrogel polymer networks for injectable, sprayable, and coating applications.

Embedded Fe‐Cu Pairs Enable Tandem Nitrate‐to‐Ammonia Electroreduction

Advanced Materials, EarlyView.
A tandem Fe‐Cu pair catalyst, composing a single copper atom (Cu–N3) coordinated to adjacent iron clusters (Fe3N8), is designed. The electron‐deficient copper sites markedly enhance nitrate adsorption, while the electron‐rich iron clusters facilitate nitrite adsorption and water activation, thereby accelerating the electroreduction of nitrate and ...

The Decoration of ZnO Nanoparticles by Gamma Aminobutyric Acid, Curcumin Derivative and Silver Nanoparticles: Synthesis, Characterization and Antibacterial Evaluation

Nanomaterials, 2021
Zinc oxide nanoparticles (ZnO NPs) are applied in various applications in catalysis, biosensing, imaging, and as antibacterial agents. Here we prepared ZnO nanomaterials decorated by γ-aminobutyric acid (GABA), curcumin derivatives (CurBF2) and silver ...

Tunable Plasmonic Response of Silver Nanoparticles Entangled in Detonation Nanodiamond Network via Colloidal Self‐Assembly

Advanced Materials Interfaces, EarlyView.
Detonation nanodiamonds form a network that entangles silver nanoparticles into stable nanocomplexes. The structure can fine‐tune and enhance plasmonic absorption through nearfield electromagnetic interactions but prevents silver particle aggregation. The study shows how the arrangement and concentration of particles affect light absorption, offering a

Green Synthesis of Highly Luminescent Carbon Quantum Dots from Lemon Juice

Journal of Nanotechnology, 2019
Highly luminescent carbon dots (C-dots) were synthesized by the one-pot simple hydrothermal method directly from lemon juice using different temperatures, time, aging of precursors, and diluted solvents to control the luminescence of C‐dots. The obtained

An Atlas of Spectrophotometric Landolt Standard Stars

, 2005
We present CCD observations of 102 Landolt standard stars obtained with the R-C spectrograph on the CTIO 1.5 m telescope. Using stellar atmosphere models we have extended the flux points to our six spectrophotometric secondary standards, in both the blue

Molecular Signatures in the Near Infrared Dayside Spectrum of HD 189733b [PDF]

, 2008
We have measured the dayside spectrum of HD 189733b between 1.5 and 2.5 microns using the NICMOS instrument on the Hubble Space Telescope. The emergent spectrum contains significant modulation, which we attribute to the presence of molecular bands seen ...

Near‐Infrared‐Driven Metal–Organic Frameworks‐Based Nanorobots for Controlled Photothermal‐Chemical Therapy Synergistic Induction of Cancer Cell Death

Advanced Robotics Research, EarlyView.
To achieve efficient cancer cell death, a bowl‐shaped PDA@UiO‐66@DOX nanorobot drug‐delivery nanoplatform was developed. Near‐infrared irradiation not only drives the nanorobot to exhibit self‐thermophoretic motion and elevates temperature but also triggers Doxorubicin (DOX) release via hyperthermia, enhancing cancer cells uptake of DOX and thereby ...

Assessing variability of literature based methane indicator traits in a large dairy cow population

Biotechnologie, Agronomie, Société et Environnement, 2015
Description of the subject. Dairy production is identified as a major source of methane (CH4) emissions. Selective breeding represents one method for mitigating CH4 emissions but practical and cheap ways to measure this trait are not currently available.
