BiOI is a nontoxic semiconductor that absorbs visible light and has already been studied for use in solar cells. Its two chemical elements, bismuth and iodine, absorb X-rays, but previous attempts to create X-ray detectors with the material failed because defects in its nanocrystalline structure caused major energy loss. Now, researchers from the universities of Oxford and Cambridge, UK, have developed a way of producing single crystals that greatly reduces structural defects and increases the sensitivity and limits of X-ray detection. In the future, this material could make medical imaging safer through the use of lower doses of radiation, preventing harm to patients (<em>Nature Communications<\/em>, April 28; <em>University of Cambridge Newsletter<\/em>, May 10).<\/p>\n","protected":false},"excerpt":{"rendered":"Material used in solar panels can detect smaller X-ray doses with better accuracy than existing medical equipment","protected":false},"author":475,"featured_media":497529,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[1651],"tags":[243,247],"coauthors":[785],"class_list":["post-497601","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-notes","tag-innovation","tag-medicine"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/497601","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=497601"}],"version-history":[{"count":1,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/497601\/revisions"}],"predecessor-version":[{"id":497602,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/497601\/revisions\/497602"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media\/497529"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=497601"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=497601"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=497601"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=497601"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
