Hutchinson, a professor at the University of Oregon, United States, and director of the Safer Nanomaterials and Nanomanufacturing Initiative, wants to change that.\u00a0 Hutchinson says, for too long, nano development has been split into two groups: one developing applications, and the other working on the implications of this emerging technology on the environment and people.\u00a0 \u201cThe vision that we\u2019ve had is to really enhance that feedback loop between those two groups,\u201d Hutchison said.\u00a0 Hutchinson describes two examples of how to make \u201cgreen chemistry\u201d a deeper shade of green.\u00a0 A method developed by his students involved finding a more benign way to make gold nanoparticles \u2013 a process that traditionally requires two highly toxic gases.\u00a0 The students used different materials, and, in so doing, found that their process was cheaper and yielded more particles.\u00a0 Another way scientists can get greener is to change the way they purify nanoparticles.\u00a0 Purification is a key step in getting a substance that works well in a test environment.\u00a0 Reducing the resources used, whether it\u2019s water or chemicals, is a positive step, he said.\u00a0 Furthermore, says Hutchinson, if manufacturers can avoid using any toxic elements, it is another way to avoid trouble down the line, as is developing production methods that use less energy and resources.<\/p>\n<p>http:\/\/www.newhavenindependent.org\/index.php\/archives\/entry\/giving_nano_a_deeper_hue_of_green\/id_36381<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nanotechnology\u2019s dirty little secret, according to this article, is that while using nanoscale materials may hold great promise, making these [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[34],"tags":[],"class_list":["post-2424","post","type-post","status-publish","format-standard","hentry","category-technology-update"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
