Reported herein is the preparation of a series of TMD NDs, including TMD quantum dots (e.g. MoS\n                    <jats:sub>2<\/jats:sub>\n                    , WS\n                    <jats:sub>2<\/jats:sub>\n                    , ReS\n                    <jats:sub>2<\/jats:sub>\n                    , TaS\n                    <jats:sub>2<\/jats:sub>\n                    , MoSe\n                    <jats:sub>2<\/jats:sub>\n                    and WSe\n                    <jats:sub>2<\/jats:sub>\n                    ) and NbSe\n                    <jats:sub>2<\/jats:sub>\n                    NDs, from their bulk crystals by using a combination of grinding and sonication techniques. These NDs could be easily separated from the\n                    <jats:italic>N<\/jats:italic>\n                    \u2010methyl\u20102\u2010pyrrolidone when post\u2010treated with n\u2010hexane and then chloroform. All the TMD NDs with sizes of less than 10\u2005nm show a narrow size distribution with high dispersity in solution. As a proof\u2010of\u2010concept application, memory devices using TMD NDs, for example, MoSe\n                    <jats:sub>2<\/jats:sub>\n                    , WS\n                    <jats:sub>2<\/jats:sub>\n                    , or NbSe\n                    <jats:sub>2<\/jats:sub>\n                    , mixed with polyvinylpyrrolidone as active layers, have been fabricated, which exhibit a nonvolatile write\u2010once\u2010read\u2010many behavior. These high\u2010quality TMD NDs should have various applications in optoelectronics, solar cells, catalysis, and biomedicine.\n                  <\/jats:p>","DOI":"10.1002\/anie.201501071","type":"journal-article","created":{"date-parts":[[2015,3,11]],"date-time":"2015-03-11T09:26:51Z","timestamp":1426066011000},"page":"5425-5428","source":"Crossref","is-referenced-by-count":204,"title":["A Facile and Universal Top\u2010Down Method for Preparation of Monodisperse Transition\u2010Metal Dichalcogenide Nanodots"],"prefix":"10.1002","volume":"54","author":[{"given":"Xiao","family":"Zhang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhuangchai","family":"Lai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhengdong","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chaoliang","family":"Tan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bing","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meiting","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linghai","family":"Xie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hua","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,3,11]]},"reference":[{"key":"e_1_2_2_1_2","unstructured":"\u00a0"},{"key":"e_1_2_2_2_2","doi-asserted-by":"publisher","DOI":"10.1039\/C4CS00269E"},{"key":"e_1_2_2_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/nmat2378"},{"key":"e_1_2_2_4_2","doi-asserted-by":"publisher","DOI":"10.1039\/c2ee22982j"},{"key":"e_1_2_2_5_2","unstructured":"\u00a0"},{"key":"e_1_2_2_6_2","doi-asserted-by":"publisher","DOI":"10.1039\/c2cs35387c"},{"key":"e_1_2_2_7_2","doi-asserted-by":"publisher","DOI":"10.1038\/nchem.1589"},{"key":"e_1_2_2_8_2","doi-asserted-by":"publisher","DOI":"10.1038\/nnano.2012.193"},{"key":"e_1_2_2_9_2","unstructured":"C.
