Zacharias Fthenakis; Antonios Fountoulakis; Ioannis Petsalakis; Nektarios Lathiotakis

Volume 13, Issue 3 , July 2022

http://dx.doi.org/10.5185/amlett.2022.031700

Abstract
  This work is part of a systematic study on the energy barriers for the permeation of several molecules, like He, H2, CO, CO2, H2O, NH3, CH4 etc, through nanoporous single layer graphene, having pores with different shape, size, and type. In the present work, we focus on the permeation of CO2 through ...  Read More

Volume 13, Issue 1 , January 2022, , Pages 2201-1685

http://dx.doi.org/10.5185/amlett.2022.011685

Abstract
  This paper addresses the design of a reactor system for manufacturing carbon nanotube (CNT) fabric and carbon hybrid materials (CHM). A web or sock of CNT is formed in a reactor tube in the gas phase pyrolysis method. The sock exits the reactor tube and is wound layer by layer onto a drum to directly ...  Read More

Volume 13, Issue 1 , January 2022, , Pages 2201-1688

http://dx.doi.org/10.5185/amlett.2022.011688

Abstract
  A new kind of transistor device with a graphene monolayer embedded between two n-type silicon layers is fabricated and characterized. The device is called graphene-base heterojunction transistor (GBHT). The base-voltage controls the current of the device flowing from the emitter via graphene to the collector. ...  Read More

Synthesis Tuning for Manufacturing Carbon Hybrid Materials

Sung Yong Kim; Megha Chitranshi; Anuptha Pujari; Vianessa Ng; Ashley Kubley; Ronald Hudepohl; Vesselin Shanov; Devanathan Anantharaman; Daniel Chen; Devika Chauhan; Mark Schulz

Volume 12, Issue 11 , December 2021, , Pages 1-8

http://dx.doi.org/10.5185/amlett.2021.111682

Abstract
  The overall hypothesis for this paper is that accurately tuning the gas phase pyrolysis synthesis process and using appropriate raw materials will enable manufacturing different types of carbon hybrid materials (CHM). Optimizing multiple variables including particle melting and vaporization temperatures, ...  Read More
