Gelatin/Alginate hydrogels were engineered for bioplotting in tissue engineering. One major drawback of hydrogel scaffolds is the lack of adequate mechanical properties. In this study, using a bioplotter, we constructed the scaffolds with different pore architectures by deposition of gelatin/alginate hydrogels layer-by-layer. The scaffolds with different crosslinking degree were obtained by post-crosslinking methods. Their physicochemical properties, as well as cell viability, were assessed. Different crosslinking methods had little influence on scaffold architecture, porosity, pore size and distribution. By contrast, the water absorption ability, degradation rate and mechanical properties of the scaffolds were dramatically affected by treatment with various concentrations of crosslinking agent (glutaraldehyde). The crosslinking process using glutaraldehyde markedly improved the stability and mechanical strength of the hydrogel scaffolds. Besides the post-processing methods, the pore architecture can also evidently affect the mechanical properties of the scaffolds. The crosslinked gelatin/alginate scaffolds showed a good potential to encapsulate cells or drugs.

Of the various dopant precursors, TiCl(3) was well recognized due to its pronounced catalytic effect on the reversible dehydrogenation processes of sodium aluminium hydrides. Quite recently we experimentally found that TiF(3) was even better than TiCl3 in terms of the critical hydrogen storage properties of the doped hydrides, in particular the dehydriding performance at Na(3)AlH(6)/NaH + Al step at moderate temperature. We present here the DFT calculation results of the TiF(3) or TiCl(3) doped Na(3)AlH(6). Our computational studies have demonstrated that F(-) and Cl(-) anions differ substantially from each other with regard to the state and function in the doped sodium aluminium hydride. In great contrast to the case of chloride doping where Cl(-) anion constitutes the \"dead weight'' NaCl, the fluoride doping results in a substitution of H(-) by F(-) anion in the hydride lattice and accordingly, a favorable thermodynamics adjustment. These results well explain the observed dehydriding performance associated with TiF(3)/TiCl(3)-doping. More significantly, the coupled computational and experimental efforts allow us to put forward a \"functional anion'' concept. This renews the current mechanism understanding in the catalytically enhanced sodium alanate.","authors":[],"categoryName":"|","doi":"","fpage":"1499","id":"6d09cb0d-2fcc-4970-b102-9d289b04851f","issue":"12","journal":{"abbrevTitle":"PCCP","id":"c3cd9a3f-bac1-4dbc-b490-7a3781d33479","issnPpub":"1463-9076","publisherId":"PCCP","title":"Physical Chemistry Chemical Physics"},"keywords":[{"id":"5daeace5-7922-4c00-add2-c41a977a645e","keyword":"total-energy calculations;x-ray-absorption;wave basis-set;structural-characterization;aluminum hydrides;ti;naalh4;diffraction;libh4","originalKeyword":"total-energy calculations;x-ray-absorption;wave basis-set;structural-characterization;aluminum hydrides;ti;naalh4;diffraction;libh4"}],"language":"en","publisherId":"1463-9076_2007_12_1","title":"Functional anion concept: effect of fluorine anion on hydrogen storage of sodium alanate","volume":"9","year":"2007"},{"abstractinfo":"The anionic species of the SiO_2-containing sodium aluminate solutions prepared by different methods have been investigated by Raman spectra and ultraviolet spectra.It was found that these solutions have different SiO_2-containing anions.The solution prepared by leaching in- dustrial sinter of soda-lime sintering process contains polvsilicate ions with Si-O-Si radicals.","authors":[{"authorName":"LIU Miaoxiu ZHOU Peifang CHEN Nianyi Shanghai Institute of Metallurgy","id":"05543384-cc92-4233-88a8-c4dcad587a93","originalAuthorName":"LIU Miaoxiu ZHOU Peifang CHEN Nianyi Shanghai Institute of Metallurgy"},{"authorName":"Academia Sinica","id":"0f77ae3b-40b3-4f84-89bc-53e77d80432c","originalAuthorName":"Academia Sinica"},{"authorName":"Shanghai","id":"cae6a8cc-669d-44ab-8e8c-6768e64f83c4","originalAuthorName":"Shanghai"},{"authorName":"ChinaLI Yu Shanghai University of Science and Technology","id":"3c3e05e4-f7aa-4a94-9840-b0fc2f01b117","originalAuthorName":"ChinaLI Yu Shanghai University of Science and Technology"},{"authorName":"Shanghai","id":"8d1546c6-fda9-427b-8e00-69c0e7a8ca74","originalAuthorName":"Shanghai"},{"authorName":"ChinaKE Jiajun Institute of Chemical Metallurgy","id":"2ae264c4-9bd5-4cd9-a972-ec231c0e4a31","originalAuthorName":"ChinaKE Jiajun Institute of Chemical Metallurgy"},{"authorName":"Academia Sinica","id":"93cd8442-1fa8-42fd-b4a9-e315f466b734","originalAuthorName":"Academia Sinica"},{"authorName":"Beijing","id":"84c1287d-a7bf-40a7-9be1-81e3e0cff3cd","originalAuthorName":"Beijing"},{"authorName":"China","id":"77ad7c8b-54c4-49a9-bc85-2489d5742686","originalAuthorName":"China"}],"categoryName":"|","doi":"","fpage":"431","id":"254de8d2-0ff8-4f6b-9dd3-6007a36c8691","issue":"12","journal":{"abbrevTitle":"JSXBYWB","coverImgSrc":"journal/img/cover/amse.jpg","id":"49","issnPpub":"1006-7191","publisherId":"JSXBYWB","title":"金属学报(英文版)"},"keywords":[{"id":"5cf6a3d3-d2a8-4ddf-b202-53766e83905c","keyword":"silicate anion","originalKeyword":"silicate anion"},{"id":"669089e9-8092-4f29-ab3d-333508dc75bd","keyword":"null","originalKeyword":"null"},{"id":"e6c31f83-20dd-4f07-aac6-9dc26fccf7f9","keyword":"null","originalKeyword":"null"}],"language":"en","publisherId":"1006-7191_1990_12_14","title":"ANIONIC SPECIES OF SiO_2-CONTAINING SODIUM ALUMINATE SOLUTIONS","volume":"3","year":"1990"},{"abstractinfo":"The addition of an alkali has been identified as a simple but effective approach for promoting aluminium (Al)/water (H(2)O) reactions.

Furthermore, the addition of a small amount of Na2SnO3 causes a remarkable decrease of NaOH concentration, which is required for achieving favorable system performance.

In the preliminary mechanistic study, the solid samples that were collected at different reaction stages were examined by X-ray diffraction, X-ray photoelectron spectroscopy and scanning electron microscopy. Our study showed that the most likely mechanism for the promoting effect of Na(2)SnO(3) is the in situ deposition of metallic Sn particles on the Al surface, which act as local inhibitors of the repassivation of Al.","authors":[],"categoryName":"|","doi":"","fpage":"2206","id":"8ad85e6e-bff4-481b-a095-6a2eb19e3af8","issue":"6","journal":{"abbrevTitle":"E&ES","id":"3a3c4409-4985-4feb-8d22-43875e588871","issnPpub":"1754-5692","publisherId":"E&ES","title":"Energy & Environmental Science"},"keywords":[{"id":"5bdc82af-27e8-4063-891c-23c9375af4df","keyword":"generation;water;storage;al;hydrolysis;corrosion;energy;metal","originalKeyword":"generation;water;storage;al;hydrolysis;corrosion;energy;metal"}],"language":"en","publisherId":"1754-5692_2011_6_1","title":"Reaction of aluminium with alkaline sodium stannate solution as a controlled source of hydrogen","volume":"4","year":"2011"},{"abstractinfo":"The corrosion behavior of LY12 alloy in sodium chloride solution and its electrochemical noise were reported.
