Graphene Mode-Locked Ultrafast Laser



Graphene Mode-Locked Ultrafast Laser





ABSTRACT Graphene is at the center of a significant research effort. Near-ballistic transport at room

temperature and high mobility make it a potential material for nanoelectronics. Its electronic and mechanical

properties are also ideal for micro- and nanomechanical systems, thin-film transistors, and transparent and

conductive composites and electrodes. Here we exploit the… Continue

Graphene mode-lockers for fiber lasers functioned with evanescent field interaction





Graphene mode-lockers for fiber lasers functioned with evanescent

field interaction





Employing graphene as an intracavity passive power modulating element, we demonstrate the

efficient laser pulsation in high pulse-energy regime with evanescent field interaction between the

propagating light and graphene layer. Graphene is prepared by the solution based reduction of

graphene… Continue

raphene-based long-wave infrared TM surface plasmon modulator





Graphene-based long-wave infrared TM surface plasmon modulator



We describe theoretically a new long-wave infrared optical modulator based on the characteristics of TM surface plasmons in graphene. Calculations made using a finite-τ random

phase approximation model, of relevant surface

plasmon propagation parameters, are presented. We show that the plasmon losses vary as…

PhD Studentship Available in Scanning Probe Microscopy of Biomolecular Surfaces - Dublin, Ireland





Investigating Electrostatic Interactions in Biomolecular Systems at the Nanoscale



Nanoscale characterization of electric charge and electric surface potentials in biomolecular systems is critical for understanding biomolecular interactions. Changes in surface potential dictate cellular-membrane transport and thus provide a crucial pathway for cells to interact with their environment. This project will focus on

investigating… Continue

My science fiction titled "The House" published in www.kalkion.com

Dear friends,

Greetings to all. I am pleased to inform you that my science fiction titled "The House" has been published in www.kalkion.com . You can see it in the Fiction-X section.

The gist of the fiction is : Ranjani wants to meet a guy living atop a hill. When she wants to land her sky vechicle near his house it shrinks inwards and expands. She is afraid to go into this…

Transient Optical Studies of Interfacial Charge Transfer at Nanostructured Metal Oxide/PbS Quantum Dot/Organic Hole Conductor Heterojunctions

We report a transient absorption and luminescence study addressing the charge separation, recombination, and regeneration reactions at nanostructured metal oxide/PbS quantum dot/organic hole conductor

heterojunctions. We show that yields of charge separation are

significantly higher at PbS/SnO2 interfaces relative to PbS/TiO222. We also report a correlation between the PbS particle size and the…

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
