Nanotechnologie PDF

Nanotechnology is the study of phenomena and fine-tuning of materials at atomic, molecular and macromolecular scales, where properties differ significantly from those at a larger scale. The current direct employment in the nanomaterial sector is estimated at 300 000 to 400 000 in Europe. In recent years, many new nanomaterial-related applications have been developed. Those include a number of consumer nanotechnologie PDF such as UV-filters in sun creams and anti-odour textiles.

Die Nanotechnologie ist die große Querschnittstechnologie des 21. Jahrhunderts. Ihre Anwendungsbereiche reichen von Computern mit bisher unvorstellbarer Leistungsfähigkeit bis hin zu völlig neuen Krebstherapien.
Dieses Buch bietet Studierenden der Natur- und Ingenieurwissenschaften, aber auch für die berufsbegleitende Weiterbildung und für interessierte Laien, einen umfassenden Überblick über die interdisziplinären Grundlagen und industriellen Anwendungen. Bestimmte Schlüsselthemen von grundlegender Bedeutung, wie etwa die Rastersondenverfahren oder die Nanobiotechnologie, werden in Form vertiefender Kapitel ausführlich behandelt.

However, many medical and technical applications such as tumour therapies, lithium-ion batteries which can drive electrical cars, or solar panels also exist. Possible risks are related to specific nanomaterials and specific uses. Therefore, nanomaterials require a risk assessment, which should be performed on a case-by-case basis, using pertinent information. As part of the Communication on the Second Regulatory Review on Nanomaterials, the European Commission will launch an impact assessment to identify and develop the most adequate means to increase transparency and ensure regulatory oversight on nanomaterials. A public consultation was conducted in support of the impact assessment. The European Commission received 202 responses to this public consultation. 100 respondents submitted the questionnaire for industry stakeholders, while 102 respondents submitted the questionnaire for other stakeholders.

14 respondents requested that their contributions would not be published. A full summary and analysis of the public consultations will be published in due course. The Commission has launched a public consultation on the modification of the REACH Annexes on nanomaterials. The consultation will run from 21 June to 13 September 2013 and is open to all interested stakeholders.

The objective of this policy initiative is to ensure further clarity on how nanomaterials are addressed and safety demonstrated in registration dossiers. DG Enterprise and Industry launched a call for tenders titled ‚ Study to assess the impact of possible legislation to increase transparency on nanomaterials on the market‘ with the deadline set for 19 August 2013. Commission to the launch of an Impact Assessment that would ‚include those nanomaterials currently falling outside existing notification, registration or authorisation schemes‘.
