Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): The objective of this work is to create a device that deposits carbon nanotubes from a floating catalyst chemical vapour deposition reactor to a substrate in one process, without extra steps.
This will create a conductive transparent thin film which can be used as raw material for the electronics industry.
The device works as proof of concept for a novel collection method.

The theoretical part of this work describes properties and applications for carbon nanotubes and the dominant production methods.
Product development methods are also presented and a deeper analysis of methods presented by Otto & Wood.

Utilizing impaction and an electric field the device collects the nanotubes from the aerosol straight to the substrate.
The produced thin film is conducting and a uniform nanotubes layer covers the film.
Most of the customer needs were satisfied and the product development project was a success.
The device can work as a modular test platform in the future
Abstract (fin): Tämän työn tarkoitus on suunnitella laite, joka kerää hiilinanoputket reaktorista tulevasta aerosolista.
Prosessissa ei ole välivaiheita ja hiilinanoputket kerätään suoraan kalvolle.
Kalvosta muodostuu sähköä johtava ohutkalvo, jota voidaan käyttää raaka-aineena elektroniikkateollisuudessa.
Laite toimii proof of concept:ina uudelle keräysmetodille.

Kirjallisuuskatsaus käsittelee hiilinanoputkien ominaisuuksia ja käyttömahdollisuuksia sekä myös tuotantomenetelmiä.
Erilaisia tuotekehitysmenetelmiä esitellään ja syvempi katsaus tehdään Otto and Wood:n esittämiin metodeihin.

Impaktion ja sähköstaattisen keräyksen avulla laite kerää hiilinanoputkia aerosolista suoraan kalvolle.
Tuotettu ohutkalvo on johtava ja hiilinanoputket ovat tasaisesti jakautuneet sen pinnalle.
Suurin osa asiakkaan tarpeista täytettiin ja tuotekehitysprojekti oli onnistunut.
Jatkossa laite voi toimia modulaarisena testilaitteena.
