These europium silsesquioxane complexes are highly soluble in organic solvents and show a red emission. Photoluminescence of Eu3+-CF-POSS is higher compared with Eu3+-CH-POSS. This fluorescence enhancement is due to the significant effect of the large POSS units. The europium silsesquioxane complexes were characterized by Fourier transform infrared spectrophotometer (FT–IR), field emission scanning electron microscopy (FE–SEM), energy dispersive X-ray analysis (EDX) and thermogravimetric analysis (TGA). The excitation and emission pattern of polyhedral europium silsesquioxanes was studied using photoluminescence spectrophotometer. The results show an excellent emission property at the wavelength between 612 and 620 nm which correspond to the 5D0–7F2 transition of europium in polyhedral silsesquioxanes.","PeriodicalId":8523,"journal":{"name":"Asian Journal of Nanoscience and Materials","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79678078","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}

Nowadays Lithium-ion batteries (LIBs) appeared to be one of the most important energy storage technologies. Today’s Li-ion technology has conquered the portable electronic markets and still on the track of fast development. The success of lithium-ion technology will depend largely on the cost, safety, cycle life, energy, and power, which are in turn determined by the component materials used for its fabrication. Accordingly, this review focuses on the challenges of organic based materials and prospects associated with the electrode materials. Specifically, the issues associated with organic based batteries, advances and prospects are presented. This review aims to summarize the fundamentals of the polymer-based material for lithium-ion batteries (LIBs) and specifically highlight its recent major advancement in material design, challenges, performance and finally its prospects. We anticipate that this Review will inspire further improvement in organic electrolyte materials and the electrode for the battery as energy device storages. Some of these concepts, relying on new ways to prepare electrode materials by the use of eco-efficient processes, on the use of organic rather than inorganic materials in order to overcome environmental issues associated with their use. Organic electrodes are important for solid electrode batteries because they can make device cost-effective, allow flexibility, and can also enable the use of multivalent ions without the problems typically associated with inorganic compounds.","PeriodicalId":8523,"journal":{"name":"Asian Journal of Nanoscience and Materials","volume":"61 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80584839","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}

And, chitosan is an eco-friendly nano-adsorbent to remove oils, grease, heavy metals and the fine particulate matter from water solution. Electronic and structural properties of chitosan during functionalization by metal were studied by density functional theory (DFT) calculations. Isolated and functionalized chitosan were optimized and their properties were evaluated. The results indicated that the properties of linking sites detect the most significant effects of functionalization process. Degradation efficiency of MX and its analogous in water solvent and also the possibility of absorption of MX by chitosan nanoparticles in aqueous solution were studied via different level of theory.","PeriodicalId":8523,"journal":{"name":"Asian Journal of Nanoscience and Materials","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85437150","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}

Regardless of its positive features, its application is hampered by its low water solubility, bioavailability, and low cellular uptake. During last year’s several ways have been developed to protect curcumin from degradation and increase its capability to targeting unhealthy cells. The progress in nanotechnology encouraged nanotechnologists to formulate nanoparticles encapsulating curcumin, such as polymer nanoparticles, solid nanoparticles, liposome/lipid nanoparticles, micelles, dendrimers, polymer conjugates, etc. to enhance sustained release of curcumin at target cells and to improve curcumin bioavailability. Nowadays newer formulations of nanoparticles as called Hybrid nanoparticles are designed in order to efficient and specific targeting of curcumin that result in improved therapeutic efficacy of curcumin with high biocompatibility with the aid of aptamers, folic acid, chitosan coated halloysite loaded with curcumin-Au hybrid nanoparticle and so on. This review describes a number of hybrid nanoparticles formulated and their efficacy in specific targeting to cancerous cells.","PeriodicalId":8523,"journal":{"name":"Asian Journal of Nanoscience and Materials","volume":"150 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76416214","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}
