The processing conditions of ACNs nanoliposomes (ANLs) were optimized, and the ANLs were characterized by average particle size, zeta (ζ)-potential and polydispersity index (PDI). Their storage stability under various pH, temperature, light conditions, and in vitro antiproliferative effect were analyzed. The optimal preparation parameters were suggested to be soy lecithin to cholesterol ratio of 80 mg to 19 mg (w/w, 2 mg of ACNs) by using ultrasonication at 120 W for 3.12 min. The produced ANLs had the encapsulation efficiency of 40.1 % with average particle size of 117 nm, PDI of 0.254 and ζ-potential of 8.56 mV. These ANLs presenting ≈ 130 nm of stable sizes at tested pH conditions. The ACNs showed better in vitro antiproliferative effect for two cancer cell lines than ANLs, while ANLs were more stable against temperature and light. The ACNs in nanoliposomes displayed higher retention efficiency than that of in solution under various storage conditions. This study provides a promising approach for stabilizing ACNs-containing food ingredients, which displays large potentiality in the productions of nutraceutical and functional foods.","PeriodicalId":9858,"journal":{"name":"Chemical Engineering (Engineering) eJournal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73724255","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}

Due to the uncontrolled pore structure and large grain size, the osteoinductivity of the conventional BCP bioceramics is restricted to a large extent. Herein, this study introduced a novel pore foaming method to fabricate BCP bioceramics with appropriately ordered macropores and abundant micropores by combing the advantages of the microsphere-sintering method with the H2O2 gas foaming method. Moreover, different sintering methods were adopted to adjust the micro-nano topography of BCP bioceramics. Due to the optimal design of pore size distribution and nano topography, the obtained BCP bioceramics could well trigger and regulate in vitro biological responses, such as degradation, bone-like apatite formation, protein adsorption, cell behaviors, angiogenic and osteogenic differentiation. In vivo canine intramuscular implantation further confirmed that the nanotopography and appropriately ordered pore structure might be responsible for the excellent neovascularization and osteoinductivity of the obtained BCP bioceramics. Collectedly, the osteoinductivity of BCP bioceramics was further enhanced by optimally designing pore structure and micro-nano topography, which hold huge potential to be a potential alternative to the gold standard of autogenous bone in bone repairing applications.","PeriodicalId":9858,"journal":{"name":"Chemical Engineering (Engineering) eJournal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84152089","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}

These three materials were prepared by cost effective co-precipitation method. While the thick film sensor was design by screen printing photolithography technique. The fabricated materials were characterized by several techniques. The structural properties of the screen-printed thick films measured by X-ray diffractometer (XRD), which confirms the formation of tetragonal SnO2 nanoparticles with average particle size between 15 -17 nm. The morphological properties of fabricated thick of SnO2 were studied by scanning electron microscopy (SEM), and HR-TEM to get surface and lattice characteristics of prepared material. The EDS technique was utilized to get the elemental composition of the prepared thick film sensors. While the UV-DRS technique was used to get the band gap energy of undoped SnO2 and modified SnO2 sensors. Since, the sensors effectively work over the surface, hence the prepared sensors were investigated by BET) study, from BET results the cobalt modified SnO2 found to be higher surface area. These all-prepared sensors were applied for gas sensing results of NO2, LPG, CO and volatile organic compounds (VOC’S). The modified sensors found to be very effective at NO2 and VOC gas vapours with 80.23 % and 69.13% gas response for cobalt modified SnO2 was observed. The tested gases NO2 and VOC found to be very selective modified sensors. Reusability and recycling results demonstrate that Co2+ doped SnO2 is very efficient, long time stable and reproducible sensor at NO2 and VOC gases.","PeriodicalId":9858,"journal":{"name":"Chemical Engineering (Engineering) eJournal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75409297","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}
