Celdas solares orgánicas como fuente de energía sustentable

open access: yesActa Universitaria, 2012
Las celdas solares inorgánicas han mostrado un gran desarrollo, sin embargo el alto costo de producción ha imposibilitado su amplio uso.  Por otro lado, el empleo de materiales orgánicos en la fabricación de celdas es una alternativa actualmente ...

Generating clean few-cycle pulses in an all-bulk multipass cell scheme [PDF]

open access: yesEPJ Web of Conferences
We theoretically demonstrate the generation of clean few-cycle pulses in a three-stage all-bulk multipass cell scheme. By meticulously selecting the number of round trips and the width of the material used in each cell, we are able to keep the three ...

Disordered plasmonic system with dense copper nano‐island morphology

open access: yesNanophotonics, Volume 14, Issue 12, Page 2151-2160, June 2025.
Abstract Dry synthesis is a highly versatile method for the fabrication of nanoporous metal films, since it enables easy and reproducible deposition of single or multi‐layers of nanostructured materials that can find intriguing applications in plasmonics, photochemistry and photocatalysis, to name a few.

Biocompatibility of Water‐Dispersible Pristine Graphene and Graphene Oxide Using a Close‐to‐Human Animal Model: A Pilot Study on Swine

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 10, April 15, 2025.
Graphene‐based materials are attracting considerable interest for biomedical applications. Analysis of their biocompatibility is required before their clinical translation, and swine represents an excellent close‐to‐human model. This study evaluates the toxicological and immunological impact of pristine graphene and graphene oxide through a compendium ...
