For sustainable and responsible development of nanomaterials technology, the establishment of ethical system for sound social acceptance of the technology as well as the development of the technology itself is necessary. In this paper, global efforts to identify and resolve the ethical issues regarding nanotechnology is reviewed, in particular the environmental, health and safety issues in nanomaterials, and the tools such as communication and engagement of stakeholders, regulations, certifications and workplace guidelines are scrutinized. Finally the policy recommendations for the establishment of ethical systems for safe usage of nanomaterials.

Effect of Injection Stage of SF₆Gas Incorporation on the Limitation of Carbon Coils Geometries

Carbon coils could be synthesized on nickel catalyst layer-deposited silicon oxide substrate using C2H2 and H2 as source gases and SF6 as an additive gas under thermal chemical vapor deposition system. The characteristics (formation density and morphology) of as-grown carbon coils according to the injection stage of SF 6 gas incorporation were investigated. A continuous injecting of SF6 gas flow could give rise to many types of carbon coils-related geometries, namely linear tub, micro-sized coil, nano-sized coil, and wave-like nano-sized coil. However, the limitation of the geometry as the nano-sized geometries of carbon coils could be achieved by the incorporation of SF6 in a short time (1 min) during the initial deposition stage. A delayed injection of a short time SF 6 gas flow can deteriorate the limitation of the geometries.It confirms that the injection time and its starting point of SF 6 gas flow would be very important to determine the geometries of carbon coils.
