Its large diffusivity and high reactivity allow it to contribute to a wide spectrum of physiological functions including vasodilation, immune-cytotoxic defenses, lymphatic pumping, and cellular respiration. One of the more interesting reactions of NO occurs with thiols (-SH), including those found on gluthatione and albumin, through the formation of an s-nitrosothiol\u0026nbsp;adduct. This adduct is implicated in stabilizing NO for transport throughout the body (albumin) and for mediating some of NO\u0027s signalling properties (gluthatione). We have exploited this chemistry to develop s-ntirosylated polypropylene sulfide nanoparticles that take advantage of the functionality of micelles as controlled drug delivery vehicles and can exert the physiological signaling activity of NO for therapeutic purposes.\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003EOn the Role of Bromide\u0026nbsp;Ions in Shaping Palladium Nanocrystals\u003C\/em\u003E\u003Cbr \/\u003EHsin-Chieh Peng; School of Chemistry and Biochemistry\u003C\/p\u003E\u003Cp\u003EBr- is a typical {100}-specific capping agent for several noble metals, including Pd, Pt, and Rh. We demonstrate an approach based on a combination of inductively coupled plasma mass spectrometry and X-ray photoelectron spectroscopy for quantitative analysis of the role played by Br\u2212 ions in the synthesis of Pd nanocrystals. The Br\u2212 ions were found to adsorb onto Pd{100} facets selectively with a coverage density of ca. 0.8 ion per surface Pd atom. \u0026nbsp;Based on the coverage density information, we were able to estimate the minimum amount of Br- ions needed to generate Pd nanocrystals with specific proportions of {100} and {111} facets.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Nano@Tech Featuring Two Lecture Topics by Alex Schudel; School of Materials Science and Engineering, Georgia Tech and Hsin-Chieh Peng; School of Chemistry and Biochemistry, Georgia Tech"}],"uid":"27522","created_gmt":"2013-07-12 09:31:59","changed_gmt":"2016-10-08 02:03:56","author":"Susan Perlman","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2013-11-12T11:00:00-05:00","event_time_end":"2013-11-12T12:00:00-05:00","event_time_end_last":"2013-11-12T12:00:00-05:00","gmt_time_start":"2013-11-12 16:00:00","gmt_time_end":"2013-11-12 17:00:00","gmt_time_end_last":"2013-11-12 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":["free_food"],"hg_media":{"222591":{"id":"222591","type":"image","title":"Nano@Tech","body":null,"created":"1449243535","gmt_created":"2015-12-04 15:38:55","changed":"1475894894","gmt_changed":"2016-10-08 02:48:14","alt":"Nano@Tech","file":{"fid":"197332","name":"dsc00582_4_1.jpg","image_path":"\/sites\/default\/files\/images\/dsc00582_4_1_0.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/dsc00582_4_1_0.jpg","mime":"image\/jpeg","size":4802,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/dsc00582_4_1_0.jpg?itok=5MUhLSJg"}},"222601":{"id":"222601","type":"image","title":"Nano@Tech","body":null,"created":"1449243535","gmt_created":"2015-12-04 15:38:55","changed":"1475894894","gmt_changed":"2016-10-08 02:48:14","alt":"Nano@Tech","file":{"fid":"197333","name":"gt-ecrelectrocyclotronresonance_000_0_0.jpg","image_path":"\/sites\/default\/files\/images\/gt-ecrelectrocyclotronresonance_000_0_0_0.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/gt-ecrelectrocyclotronresonance_000_0_0_0.jpg","mime":"image\/jpeg","size":5303,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/gt-ecrelectrocyclotronresonance_000_0_0_0.jpg?itok=-ItLzx_o"}},"222611":{"id":"222611","type":"image","title":"Nano@Tech","body":null,"created":"1449243535","gmt_created":"2015-12-04 15:38:55","changed":"1475894894","gmt_changed":"2016-10-08 02:48:14","alt":"Nano@Tech","file":{"fid":"197334","name":"nano_brownsmill009_000_0.jpg","image_path":"\/sites\/default\/files\/images\/nano_brownsmill009_000_0_0.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/nano_brownsmill009_000_0_0.jpg","mime":"image\/jpeg","size":4417,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/nano_brownsmill009_000_0_0.jpg?itok=4SR3iDwZ"}},"222621":{"id":"222621","type":"image","title":"Nano@Tech","body":null,"created":"1449243535","gmt_created":"2015-12-04 15:38:55","changed":"1475894894","gmt_changed":"2016-10-08 02:48:14","alt":"Nano@Tech","file":{"fid":"197335","name":"nano_brownsmill007_000_2_0.jpg","image_path":"\/sites\/default\/files\/images\/nano_brownsmill007_000_2_0_0.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/nano_brownsmill007_000_2_0_0.jpg","mime":"image\/jpeg","size":5251,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/nano_brownsmill007_000_2_0_0.jpg?itok=IcLoJNV2"}}},"media_ids":["222591","222601","222611","222621"],"groups":[{"id":"1271","name":"NanoTECH"},{"id":"197261","name":"Institute for Electronics and Nanotechnology"}],"categories":[],"keywords":[{"id":"66411","name":"Nano@TECH; nanotechnology; Marcus Nanotechnology Building"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EDr. David Gottfried\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022mailto:david.gottfried@ien.gatech.edu\u0022\u003Edavid.gottfried@ien.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
