Graphene samples preparation and some possible uses in developing optical communication devices
Journal Title: Revista Facultad de Ingeniería-Universidad de Antioquia - Year 2015, Vol 1, Issue 75
Abstract
Graphene is a two-dimensional material which has been attracting the attention of worldwide scientific community, motivated by their optical and electronic properties. There are different methods for obtaining grapheme; however, the micromechanical exfoliation process is the simplest and it allows samples with high quality to be obtained. In this paper, the preparation process of graphene flakes by exfoliation method and their characterization by Raman spectroscopy are shown. Moreover, some possible uses of graphene flakes applied to develop optical communication high speed devices are described.

Incorporación de otras materias primas como fuentes de azúcares fermentables en destilerías existentes de alcohol
This paper presents alternatives for meeting the deficit in sugared substrates in a territory with several sugar mills and ethanol distilleries so they can reach their current production capacity. By using secondary curr...
Influence of precipitation scavenging on the PM2.5/PM10 ratio at the Kennedy locality of Bogotá, Colombia
Objective: To establish whether the scavenging effect reduces the PM2.5/PM10 ratio in rainy periods in comparison with dry periods, at the Kennedy locality of Bogotá, Colombia. Materials and methods: Relationships among...
A two-stage decision support model for a retail distribution center location
This paper proposes a model to support the decision-making process of selecting the location of a distribution center for the retail sector. The model was structured in two stages to consider objective and subjective cri...
Maximum power point tracking in PV systems based on adaptive control and sliding mode control
Photovoltaic (PV) systems are commonly controlled using PI or PID structures, which cannot ensure global stability and a constant settling time. Therefore, the optimization algorithms, e.g. Perturb and Observe (P&O), are...
Simulating gas-liquid mass transfer in a spin filter bioreactor
Computational fluid dynamics (CFD) and population balance model (PBM) model have been used to simulate hydrodynamics and mass transfer in a 0.014 m3 Spin Filter Bioreactor. The operating conditions chosen were defined by...
