Ignorance about phytochemical composition particularly knowledge of the bio-active principle of medicinal plant restricts the demonstration of the real picture of the enhancement of any bio-efficacy. The present communication scientifically established anti-inflammatory bio-efficacy in seeds of the folk plant Madhuca longifolia and its significant enhancement by bio-active principle (saponin) loaded silver nanoparticles (S@AgNps). A family of four saponins has been explored quantified (3.59%) and characterized (Micro Mass ESI-TOF MS spectra). Synthesis of S@AgNps has been conducted in a green single step and thoroughly characterized. In- vivo assessment of anti-inflammatory bio-efficacy has been carried out using carrageenan induced hind paw edema in Swiss albino mice model. Anti-inflammation bio-efficacy of native seed extract (15 mg/kg/bw) was found 46.84% which was further elevated and further rose to 56.10% by saponin at considerable low optimized dose (1.5 mg/kg/bw). Anti-inflammatory bio-efficacy was further successfully enhanced to (70.99%) by S@AgNps, almost close to that of reference drug (Diclofenac sodium; 76.42%). Saponin loaded silver nanoparticles (S@AgNps) prepared from the seed extract of the plant M. longifolia seem to be an ideal candidate for the development of complimentary herbal nanomedicine for anti-inflammation.","PeriodicalId":8523,"journal":{"name":"Asian Journal of Nanoscience and Materials","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80658209","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}

In our synthesis route, FeCl3 and FeCl2 were employed as precursors to synthesize γ-Fe2O3NPs. This approach is very effective and economical.

This is due to the fact that copper and copper-based materials have the potential to convert CO2 to oxygenates such as ethanol, methanol, formates etc. and hydrocarbons such as ethane, methane etc. Mechanistic details on how these products are formed on the catalyst-electrolyte interphase during the reduction process have remained relatively uncovered. This review, therefore, seeks to uncover the mechanism of electrochemical reduction of CO2 on Cu/Cu based electrodes, factors that affect catalytic activity and selectivity for these electrodes as reported in the various literature. This paper is therefore organized as follows: section 1 covers the introduction; an overview of some basic concepts in electrochemical CO2 reduction (ECR) was discussed in section 2, experimental studies were discussed in section 3, and finally the conclusion.","PeriodicalId":8523,"journal":{"name":"Asian Journal of Nanoscience and Materials","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83948914","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}

The mechanical alloying was carried out in the attendance of various Mo contents as a micro-alloying element for various milling times. Microstructural characterization and structural changes of powder particles during mechanical alloying were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Outcomes confirmed that the synthesis behavior of NiAl intermetallic depends on the milling time and Mo content. The results show that after than 80h milling, the intermetallic phase is produced after opening the vial lid. X-ray map show that, in the fixed milling time, enhancing the Mo content leads to acceleration in the NiAl formation in air atmosphere. The mechanical alloyed powders have a microstructure consisting of nanometer size particles. Mo enhance has a considerable effect on the lowering of crystallite size.
