Because of the much larger surface area than that of the corresponding bulk liquid, DM, which contains amino-functionalized ionic liquids (ILs), is a promising CO2 absorption material provided with quick absorption speed. In the present study, we successfully prepared powdery DMs by utilizing aqueous solutions of amino acid-based ILs (tetraethylammonium glycine [N2222][Gly], and tetraethylammonium alanine [N2222][Ala]). Although a DM with lysine-based IL (N2222) [Lys]) was also prepared, only a souffle-like material was obtained. We measured CO2 absorption performance for the DMs to find that the mass-base absorption ability (mass-base A.A.) (CO2 mol/DM kg) and the mol-base one (CO2 mol/IL mol) of [N2222][Lys] were ca. two times of [N2222][Gly] and [N2222][Ala], while the absorption speed of the former was inferior to the latter two, i.e., ca.15 min vs. 5 min for 90% absorption. In order to improve the mass-base A.A. of [N2222][Gly], we used 10% of aqueous poly(allylamine) (PAlAm) solution instead of water. The resultant mass-base A.A. proved to be significantly larger (1.9) than either of those of the respective single component systems (1.1 and 0.75 for the bulk IL and aq. PAlAm, respectively), and comparable to the A.A. (1.6 - 2.5) of 20% - 30% monoethanolamine solution which is commonly used in industrial application.","PeriodicalId":12770,"journal":{"name":"Green and Sustainable Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82304540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result: 1) New technique of forming p-n junctions in silicon has been elaborated. The technique provided easy and comparatively cheap process of production of semiconductor devices such as solar cells. The essence of the technique under the study is comprised in formation p-n junctions in silicon by a change of conductivity in the bulk of the sample occurring as a result of redistribution of the impurities, which already exists in the sample before its processing by ions. It differs from the techniques of diffusion and ion doping where change of conductivity and formation of p-n junction in the sample occur as a result of introduction of atoms of the other dopants from the outside; 2) The conditions for synthesis of GaAs/Ge/Si epitaxial substrates with a thin (200 nm) Ge buffer layer featured with (1 - 2) × 105 cm-2 density of the threading dislocation in the GaAs layer. Ge buffer was obtained by chemical vapor deposition with a hot wire and GaAs layer of 1 μm thick was grown by the metal organic chemical vapor deposition. Root mean square surface roughness of GaAs layers of the less than 1 nm and good photoluminescence properties along with their high uniformity were obtained; 3) The conditions ensuring the synthesis of uniform functional (buffer, insulating and protective) fianite layers on Si and GaAs substrates by means of magnetron and electron-beam sputtering have been determined. Fianite films have been shown to be suitable for the use as an ideal anti-reflecting material with high protective and anticorrosive properties.","PeriodicalId":12770,"journal":{"name":"Green and Sustainable Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73141948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chicken \u0000manure contains rich amounts of nitrogen and phosphorus and has been \u0000used as crop fertilizer. However, little is known about whether nutrients of \u0000chicken manure are suitable and efficient to support the rapid growth of microalgae. \u0000In this study, we explore the possibility of using nutrient extracted \u0000from chicken manure to grow microalgae. We used an algal strain Scenedesmus sp. HTB1, which is an oleaginous species with high CO2 tolerance capability. \u0000The growth performance of HTB1 on various media amended with nutrient \u0000extracted from three different chicken manure sources was monitored \u0000and compared to the growth rate of HTB1 grown in the standard medium \u0000BG11. Meanwhile, the changes of total nitrogen (N) and phosphorus (P), both \u0000organic and inorganic, were measured during the growth period. Culture media \u0000enriched with the nutrient extracted from two chicken manure sources \u0000outperformed the standard culture medium BG11 in terms of algal biomass \u0000production. When cultivated with manure nutrient, HTB1 utilized inorganic \u0000N efficiently, but consumed very little organic N during the experimental \u0000growth period. However, HTB1 was able to utilize both organic and inorganic \u0000phosphorus. We demonstrate that nutrient extracted from chicken manure \u0000support rapid growth and high biomass yield in microalgae Scenedesmus obliquus HTB1. Therefore chicken manure holds great promise to be used as a \u0000cost-effective and efficient fertilizer for large-scale production of microalgae.","PeriodicalId":12770,"journal":{"name":"Green and Sustainable Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72626774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
