Warm Dark Matter Sterile Neutrinos in Electron Capture and Beta Decay Spectra

open access: yesAdvances in High Energy Physics, 2016
We briefly review the motivation to search for sterile neutrinos in the keV mass scale, as dark matter candidates, and the prospects to find them in beta decay or electron capture spectra, with a global perspective.

Biological and Biologically Inspired Functional Nanostructures: Insights into Structural, Optical, Thermal, and Sensing Applications

open access: yesAdvanced Materials, EarlyView.
Biological and biologically‐inspired functional nanostructures with structural, thermal, optical, and sensing applications are reviewed. The role of nanoscale features in biological materials on performance is described, and their blueprints are used for bio‐inspired nanomaterials, synthesized using advanced techniques (i.e., photolithography, bio ...

Challenges of II‐VI and III‐V Blue Quantum Dot Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
Blue‐emitting electroluminescent quantum dot light‐emitting diodes (QD‐LEDs) face critical challenges that limit their practical application, including short operational lifetimes, low color purity, broad spectral linewidths, and unpredictable transient effects like blinking and positive aging.

Lithium‐Charged Gold Nanoparticles: A New Powerful Tool for Lithium Delivery and Modulation of Glycogen Synthase Kinase 3 Activity

open access: yesAdvanced Materials, EarlyView.
This study introduces glutathione‐stabilized gold nanoparticles for targeted lithium delivery (LiG‐AuNPs), enabling the controlled modulation of Glycogen Synthase Kinase‐3 (GSK‐3β). These non‐toxic, 2‐nm particles release lithium intracellularly, effectively inhibiting GSK‐3β in the brain without significant plasma lithium alterations.

Rotation curves velocities obtained by warm low-density plasma simulating dark halos and “dark matter”

open access: yesAIP Advances
The free electron model with Boltzmann statistics for spherical low-density plasmas is developed further, with asymptotic relations obtaining the density of electrons, mass densities, and the potentials of such plasmas.

Antibody‐Functionalized DNA Hydrogels Recognize and Isolate Living Tumor Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
We present a novel strategy using DNA Y‐motif nanostar hydrogels and DNA‐functionalized antibodies for precise live‐cell manipulation. Target cells are labeled with DNA sticky ends that hybridize with DNA Y‐motifs, enabling their incorporation and capture within the hydrogel during self‐assembly.

Populating secluded dark sector with ultra-relativistic bubbles

open access: yesJournal of High Energy Physics
We study Dark Matter production during first order phase transitions from bubble-plasma collisions. We focus on scenarios where the Dark Matter sector is secluded and its interaction with the visible sector (including the Standard Model) originates from ...

Transparent, Sprayable Plastic Films for Luminescent Down‐Shifted‐Assisted Plant Growth

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
Spreading the light: A modular approach to down‐shifting europium‐containing polyoxotitanium luminescent cages is developed, allowing their incorporation into sprayable plastic coatings on agricultural greenhouses for accelerated plant growth. Abstract The world's steadily growing population and global heating due to climate change are a threat to food
