Where are the binary source galactic microlensing events? [PDF]

open access: yesAstron.Astrophys.333:893,1998, 1998
Though there have been some galactic microlensing events which show a clear signature of a binary lens, no event has yet been claimed as due to lensing of a binary source. Here I argue that this may be due to the fact that most of the binary source events show light curves which can be fitted with the simpler model of a blended single source.

Technoeconomic Insights into Metal Hydrides for Stationary Hydrogen Storage

open access: yesAdvanced Science, EarlyView.
Stationary hydrogen storage is essential for enabling the use of hydrogen and fuel cell technologies in applications such as backup power supply. This work evaluates the benefits of metal hydrides for storage, demonstrating the impacts of system design and operation, and material properties on viability.

Metallic nanowires: multi-shelled or filled ? [PDF]

open access: yesComputational Materials Science 18, 333 (2000), 2000
The room temperature structure of aluminum, copper and gold infinite nanowires is studied. The molecular dynamics simulation method and the same type of the embedded atom potentials made by Voter and coworkers are used. It was found that multi-shelled and various filled metallic nanowires exist depending on the metal and the initial configuration.

Manipulation of Oxygen Tension in Damaged Regions via Hypoxia‐Induced IPN Hydrogel Microspheres for Intervertebral Disc Regeneration

open access: yesAdvanced Science, EarlyView.
A novel interpenetrating network hydrogel microsphere (NSC‐Exos@HIMS) is developed to manipulate oxygen tension in damaged regions and recruit endogenous stem cells. In vitro and in vivo results show that NSC‐Exos@HIMS maintains the hypoxia microenvironment for up to 5 days, which triggers nucleus pulposus cell‐like differentiation and enhanced ECM ...

Endocrine-Disrupting Chemicals Exposure and Neurocognitive Function in the General Population: A Community-Based Study

open access: yesToxics
Background: Endocrine-disrupting chemicals (EDCs) are pervasive in everyday environments. The impacts of these chemicals, along with EDC-related lifestyle and dietary habits on neurocognitive function, are not well understood.

New Insights into Heavy Metal Sequestration Through Metal‐Phenolic Network‐Confined Nano‐HFO: Overlooking Iron Utilization and Modulating Electron Density

open access: yesAdvanced Science, EarlyView.
Iron‐based nanocomposites are widely used for trace heavy metal removal, but the low utilization of HFO nanoparticles remains a challenge. Here, a metal‐phenolic network (MPN) strategy is proposed to confine nano‐HFO within polystyrene beads, creating a negative electrostatic field and optimizing electron density at oxygen sites. This approach enhances
