Mechanical properties can be determined by carrying out mechanical testing. The mechanical properties of this research using the Impact test have been completed. In this research each test was carried out on variations in the amount of fiberglass lamination CSM 300, CSM 450 and WR 600 and the variation in weight percentages of 99.5% -0.5%, 99% -1%, 98.5% -1 , 5%, 98% -2% and 97.5% -2.5% have been used. The result show that the more the amount of laminate the greater impact strength, which is equal to 413,712 MPa, and the more the percentage hardener the greater the impact strength 2.0 wt .-%, which is equal to 416,487 MPa.

Moreover, physical and chemical methods are widely used for the synthesis of nanoparticles, but these methods have expensive and not ecofriendly. This study highlights the green, rapid, facile, cost-effective, and ecofriendly synthesis and synthesized nanoparticles also investigate their antibacterial activity. Synthesized silver nanoparticles are analyzed by different techniques of modes like XRD, UV-Visible spectroscopy, TEM, FTIR, and photoluminescence (PL). The prepared AgNPs show characteristic absorption peak in UV-Visible spectroscopy due to SPR (surface plasmonic resonance) band between 400 to 450 nm wavelength, which was confirmed by TEM (transmission electron microscopy) image. X-ray diffraction (XRD) results showed the crystalline nature of AgNPs as well as the size of nanoparticles calculated with the help of TEM (20-25 nm) and XRD (25 nm). ATR spectroscopy identified the functional groups that are involved in the reduction of silver ion to AgNPs and the PL spectrum indicates higher emission in the green region and low emission peak in the UV region. Antibacterial activity of AgNPs analyzed against with the help of E.Coli bacteria and the result shows that a higher concentration of AgNPs is increasing as well as a zone of inhibition increased.

Higher electrical conductivity of a defect form of II=VI oxides (Cd-O in particular) is highlighted for possible practical exploitations. For 2nd generation Electromagnetic Interference (EMI) Shielding, polymeric composites with either newer absorbing agents or newer reflecting agents or their mixtures will be outlined. Novel Fe- or Ni- based HTSCs (high temperature superconductors) are less anisotropic and rather metallic in contrast to Cu-oxide HTSCs.

Global warming, national calamities, fossil-fuel shortages have drawn global attention to environment friendly and renewable energy source. The hydrogen fuel cell technology most certainly fits those requisites. New researches facilitate improving performance, endurance, cost-efficiency, and overcoming limitations of the fuel cells. The various factors affecting the features and the efficiency of a fuel cell must be explored in the course of advancement in a specific manner. Temperature is one of the most critical performance-changing parameters of Proton Exchange Membrane Fuel Cells (PEMFC). In this review paper, we have discussed the impact of temperature on the efficiency and durability of the hydrogen fuel cell, more precisely, on a Proton Exchange Membrane Fuel Cell (PEMFC). We found that increase in temperature increases the performance and efficiency, power production, voltage, leakage current, but decreases mass crossover and durability.

The continuous efforts in searching for new functional and smart materials facilitated the design of miniaturized and more efficient devices, and led to great advancements in pharmaceutical, medicinal, agricultural, energy related industries, and many more. Before employment in a given application, a newly developed material needs to be fully characterized and tested for efficient delivery and fulfillment of industrial and technological requirements. This calls for establishing experimental setups equipped with modern testing facilities that could be exceedingly expensive, and time consuming. In addition, the cost of materials for experimental work could be high in some cases. The financial limitations, however, make it difficult to construct such facilities for a large fraction of researchers worldwide, especially in nations with limited financial resources. Accordingly, computational techniques have been developed to provide efficient materials characterization, and design of smart materials and devices for practical applications at a relatively low cost. These techniques are also crucial in providing detailed information about the structural and physical properties of the material at the molecular level, thus allowing for better understanding of how the material functions, and facilitating the tuning and improvement of the material’s characteristics for a specific application. However, comparison of the results of the computational techniques with experimental results is crucial to examine the reliability of the computational techniques, at least in its initial stages.","PeriodicalId":18247,"journal":{"name":"Material Science Research India","volume":"75 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77329105","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}
