Scientists have carried out a research on how ion irradiation can shape nanoscale pore. Findings of the research have been published Nature Communications recently.
Professor Ostrikov, one of the authors of the research, from QUT’s Science and Engineering Faculty and Institute of Health and Biomedical Innovation informed that it was an example of the scope to alter behavior of atoms and create new materials by using helium ion beams created in a microscope for helium ion.
It was found that a beam of proactive helium ions created in a microscope of helium ion reorganized a material of nanoporous anodized alumina on the atomic scale; it shrank pores to various, new super-small sizes.
Discovery to Help in Early Cancer Detection
Such ultra-small pores will enable scientists to “sift” molecules into various sizes so as to examine them separately. This could pave the way for detection of cancer in its early stages. For instance, via a blood test that can uncover DNA produced by a cancer before the tumor developed.
Such changing of the matter on a super micro scale leveraging ion totally altered the behavior of the aluminum oxide. On applying moderate exposure to ions of helium, its pores shrank. They upped exposure to the ions and the typically porous and brittle ceramic changed into a superplastic which could two times without breaking.
The breakthrough findings will enable scientists to tweak materials and see the materials and see their properties transform. This can be used to generate futuristic smart materials.
