Emergent dark matter in late time universe on holographic screen

Journal of High Energy Physics, 2018
We discuss a scenario that the dark matter in late time universe emerges as part of the holographic stress-energy tensor on the hypersurface in higher dimensional flat spacetime.

Functional Hydrogel for Modulating Lipid Droplets and Neuroinflammation in Head Injury

Advanced Functional Materials, EarlyView.
After TBI, elevated cholesterol levels in activated microglia lead to the accumulation of cholesterol esters in lipid droplets, exacerbating neuroinflammation. A β‐cyclodextrin‐conjugated GelMA (βCD‐GelMA) hydrogel is developed to promotes cholesterol efflux and reduces LDL influx, thereby alleviating intracellular cholesterol and lipid droplet buildup.

FeDSNP‐Pa Nanoassemblies: A Triple‐Action Therapeutic Strategy Targeting Oxidative Stress, Inflammation, and Pyroptosis for Retinal Ganglion Cell Protection in Glaucoma

Advanced Functional Materials, EarlyView.
FeDSNP‐Pa, a metallized nanoparticle loaded with sodium pyruvate (Pa), exerts triple therapeutic effects by scavenging reactive oxygen species (ROS), suppressing inflammatory responses, and inhibiting pyroptosis signaling pathways. This multifunctional neuroprotective strategy protecting retinal ganglion cells (RGCs) from elevated intraocular pressure ...

Synergistic Osteogenesis After Co‐Administration of cmRNAs Encoding BMP‐2 and BMP‐7 Utilizing a Transcript‐Activated Matrix

Advanced Functional Materials, EarlyView.
This study demonstrates that the dual delivery of BMP‐2/‐7 coding cmRNAs for bone healing is demonstrated as feasible, safe, and highly osteogenic. Compared to single BMP‐2 or BMP‐7 cmRNAs, the combination enhances the production of both mineral and organic components of the extracellular matrix when delivered using a collagen‐HA scaffold, supporting ...

Structural and Chemical Studies of the Nanoscale Modifications Induced by Swift Heavy Ion Irradiation in SrTiO3 at Grazing Incidence

Advanced Functional Materials, EarlyView.
The nanoscale structural and chemical transformations in SrTiO3 under Swift‐Heavy‐Ion irradiation at grazing incidence are investigated, emphasizing the formation of well‐ordered nanohillocks at the surface of the material, demonstrating significant material decomposition in the created hillocks with: a phase separation of SrO and TiOx, a reduction in ...

Bicontinuous Microarchitected Scaffolds Provide Topographic Cues That Govern Neuronal Behavior and Maturation

Advanced Functional Materials, EarlyView.
A scalable biomimetic platform transforms bioinert poly(ethylene glycol) diacrylate into neuroinstructive matrices via integrating solvent transfer‐induced phase separation, microfluidics, and 3D bioprinting. Bicontinuous, hyperbolically curved microporous networks embedded within a fibrous construct elicit rapid adhesion, robust proliferation, and ...
