In order to\r develop the waste material recycling process, the silica nanoparticle was prepared from\r environmental agro waste. This research intended to utilize the waste material rice straw as a\r valuable material silica nanoparticles. In this study the rice straw sample was collected from\r Hmawbi Township, Yangon Region. At first, rice straw ash was prepared from rice straw by\r calcination at 650 °C for 3 h. A chemical method of dissolution-precipitation was applied to\r produce silica nanoparticles from rice straw ash. The rice straw powder was characterized by\r using XRD, FTIR, SEM and TG-DTA. Characterization of rice straw ash, silica powder and\r silica nanoparticles were carried out by the above techniques except TG-DTA. XRD pattern of\r the silica nanoparticles confirms the amorphous nature of silica. By using Scherrer equation,\r the crystalline size of the prepared silica nanoparticles was 46.70 nm. Infrared spectral data\r support the present of hydrogen bonded silanol groups and siloxane groups on the silica. SEM\r micrograph of silica nanoparticles showed porous structure."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "rice straw ash"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "A Study on Synthesis of Silica Nanoparticles from Rice Straw.pdf", "filesize": [{"value": "322 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 322000.0, "url": {"url": "https://meral.edu.mm/record/330/files/A Study on Synthesis of Silica Nanoparticles from Rice Straw.pdf"}, "version_id": "b5cf27c3-179b-4cb9-a553-ca2b826f2401"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "1", "subitem_journal_title": "Yadanabon University Research Journal", "subitem_volume": "10"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Thida Wynn"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Journal article"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2019"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://oar.ydbu.edu.mm/handle/123456789/276"}, "item_title": "A Study on Synthesis of Silica Nanoparticles from Rice Straw", "item_type_id": "21", "owner": "1", "path": ["1582966466300"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000000330", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "330", "relation": {}, "relation_version_is_last": true, "title": ["A Study on Synthesis of Silica Nanoparticles from Rice Straw"], "weko_shared_id": -1}
