Problem of safety in nanoparticle mass production and its solution by means of advanced scanning electron microscopy
“Problem of safety in nanoparticle mass production and its solution by means of advanced scanning electron microscopy” – an article written by S.K. Maksimov and K.S. Maksimov is published by IOP: Conference Series. It is suggested possible approaches to the comprehensive solution of the problem of structural-morphological control in mass production of nanoparticles only by the use of advanced methods of scanning electron microscopy.
Currently, none of the manufactured scanning electron microscopes do not allow measure the size of nanostructure in directions not lying in the plane of projection. But even in the plane projections transition from the object image to true size of the object is a complex and not always solvable problem. Consequently, none of the modern SEM is not suitable for monitoring nanoregions, where the properties depend on the size of the object in the directions and cut (habit). It is the solution to the problem of determining the true size of the object in directions, and his habit directed the proposed solution. This is the first physically real offer in the world, which is confirmed by expert opinion.
Added a section dedicated to solving the problem of output control in the field of nanotechnology, using methods of scanning electron microscopy (SEM). Given a scientific justification of the proposed solutions, explains the basic principles of the approach and possible technological risks.
An article “New Approach to Metrology in Nanotechnology” uploaded. Published in Technical Physics Letters (Pis’ma v Zhurnal Tekhnicheskoі Fiziki), 2010, Vol. 36, No. 20, pp. 21–28. Notions of a fractional method of control in nanotechnology are presented and a key stage of the method is described that is related to determining the shape and dimensions of nanoobjects based on their scanning electron microscopy images obtained at various convergence angles of the electron probe.
(only in Russian) An article «Principles of standard safety and production control techniques for nano-sized particles» uploaded. Published in Nanotechnology magazin (Журнал Нанотехника) № 3(19), 2009, С. 5 – 12. The complex environmental problems associated with nanoparticlesand their production discussed. Their solution requires the adoption of security standards and technical regulations based on the characteristics of a three-pronged: the size-structure-cut offered.
An article “Principles of Nanomaterial Control for the Development of Safety Standards as Illustrated by Establishing the Laws of Nanostructuring in CayLa1-yF3-y and LaxCa1-xF2+x“ uploaded. Published in Technical Physics Letters (Pis’ma v Zhurnal Tekhnicheskoі Fiziki), 2009, Vol. 35, No. 3, pp. 224–227. The general principles of ecological safety control over nanomaterials are formulated. Specific features of this control for materials in the form of solid solutions are illustrated by the laws of nanostructuring in fluorite-like CayLa1-yF3-y and LaxCa1-xF2+x systems.
The problem of measurement in the nanotechnology industry – a key at this time. This task involved many scientific teams worldwide. But an adequate idea of a solution of the characterization of large arrays of nanoscale objects is not currently offered.
A lot of scientific teams try to find a way to solve the problem. Fragmentation and lack of adequate ideas leads to the loss of time and slows down development in this direction.
We proposed the way to solves this problem. OUr approach is theoretically verified. And we starting it’s implementation.
Work being done by our team, show that a practical solution to problems of measurement exists. And we want to share it.
