science television is just television [PDF]

open access: yesActes d'història de la ciència i de la tècnica, 2014
Aquest article parla de televisió, no pas de ciència. De fet, es basa en la meva pròpia experiència com a directora d'un programa de ciència (Tres14) a Televisió Espanyola. En primer lloc, s'analitzarà el fet que els professionals de la televisió no necessitin d'una formació científica per esdevenir divulgadors de ciència.

Ultrahigh‐resolution (λ/10) Femtosecond Laser Writing of Polymer‐Encapsulated Multicolor Perovskite Patterns Beyond the Diffraction Limit

open access: yesAdvanced Functional Materials, EarlyView.
Fabrication of in situ polymer‐encapsulated stable perovskite patterns of arbitrary shapes and pixel arrays with a resolution of 80 nm is reported by the femtosecond (fs) laser (800 nm) super‐resolution writing technique. The two‐photon absorption‐induced laser ablation is attributed to the achieved feature sizes as small as λ/10.

Dual‐Nanoparticle Engineered Hydrogel Reverses Bicellular Oxidative Stress to Accelerate Diabetic Fracture Healing

open access: yesAdvanced Functional Materials, EarlyView.
CD105‐LNPs and PS‐LNPs can deliver α‐lipoic acid to bone marrow mesenchymal stem cells and bone marrow‐derived macrophages, reversing high glucose‐induced oxidative stress while enhancing osteogenesis and M2 polarization. Integrating both nanoparticles into glucose‐responsive hyaluronic acid hydrogel forms DLNPs@HA hydrogel, which accelerates diabetic ...

Quasi‐Periodic Surface Functionalization by Ultra‐Short Pulsed Laser Processing: Unlocking Superior Heat Transfer in Vapor Chambers

open access: yesAdvanced Functional Materials, EarlyView.
Ultra‐short pulsed laser processing (ULSP) enables scalable, open‐air fabrication of self‐organized, quasi‐periodic micro/nanostructures on copper using 100 µm laser beams, orders of magnitude larger than the resulting surface features. Integrated into ultra‐thin, wick‐free vapor chambers, these laser‐functionalized surfaces dramatically enhance ...

Portrayal of Mental Illness on Television: A Review of the Literature [PDF]

open access: yes, 2008
The focus of this thesis is to present peer-reviewed studies relating to mental illness and television. Up to this point there has not been a review paper exclusively examining mental illness and television exclusively.

The Welfare Effects of Bundling in Multichannel Television Markets

open access: yes, 2012
We measure how the bundling of television channels affects welfare. We estimate an industry model of viewership, demand, pricing, bundling, and input market bargaining using data on ratings, purchases, prices, bundles, and input costs.

Controlled Release of Human Dental Pulp Stem Cell‐Derived Exosomes from Hydrogels Attenuates Temporomandibular Joint Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
Exosomes can reduce tissue damage in temporomandibular joint osteoarthritis (TMJOA), but rapid clearance limits their efficacy. This study encapsulates exosomes in hyaluronic acid hydrogels for controlled release. In a rat model, hydrogel‐encapsulated exosomes outperform free exosomes in preserving bone integrity and reducing tissue destruction ...
