Amorphous carbon materials (hard carbon) have micropores and impurities, facilitating the intercalation of sodium ions to form \"quasi-metallic sodium,\" resulting in a high sodium storage capacity and a low sodium storage potential. Consequently, hard carbon is one of the most widely studied negative electrode materials. It can be prepared from biomass by thermochemical conversion and has the advantages of large specific capacity, low cost, good cycling stability, and renewability. This review focuses on the recent advances in biomass-based hard carbon materials. Firstly, the preparation methods of hard carbon, including precursor selection, pretreatment, drying methods, and carbonization processes, are summarized. Secondly, the effects of precursor composition and heteroatom doping structure and properties of hard carbon are examined, and the changes in carbon material pores during the activation process, as well as the selection of optimal drying method, pyrolysis temperature, carbonization temperature, activator dosage, and additive, are discussed. Thirdly, the impact of preparation methods on hard carbon's cost, efficiency, and stability is briefly summarized, and the relevant improvement measures and prospects are proposed. Finally, some insights are provided into preparing highperformance biomass-based anode materials for sodium-ion batteries.","PeriodicalId":49324,"journal":{"name":"Recent Patents on Nanotechnology","volume":"61 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140561660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a lipid and surfactant, Gleceryl monostearate and Pluronic -68 were used in the formulation process. background: Nanotechnology is essential for developing novel methods for transporting potentially therapeutic and symptomatic substances to specific regions of the central nervous system. Since these formulations reduce the long-term adverse effects associated with the aberrant distribution of medications, they increase the drug concentration at the site of action, thereby enhancing therapeutic efficacy. Method: During characterization, it was determined that ingredient quantity variations significantly impacted Rosiglitazone loading capacity, particle size, polydispersity index, etc. In an optimized formulation of RSG-PB loaded SLNs, spherical particles with a mean particle size of 147.66±1.52 nm, PDI of 0.42±0.02, and loading capacity of 45.36±0.20 were identified. Result: Moreover, the developed SLNs had the potential to discharge the drug for up to 24 hours, as predicted by Higuchi's pharmacokinetic model. The SLNs were stable at 25⁰C/60%RH for up to 60 days. There was little to no change in particle size, PDI, or loading capacity. In addition, the number of probiotic bacteria was determined using the standard plate count procedure. Further, the antioxidant effect of the prepared formulation is evaluated using the DPPH assay method. Conclusion: This study concludes that the method used to fabricate RSG-probiotic-loaded SLNs is straightforward and yields favorable results regarding various parameters, including sustained release property, particle size, PDI, and percent drug loading stability. Furthermore, DPPH radical scavenging activity shows the high antioxidant potential of RSG-PB SLNs when compared to RSG and probiotics alone.","PeriodicalId":49324,"journal":{"name":"Recent Patents on Nanotechnology","volume":"10 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139662459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
