The research is aimed at the synthesis of 4-methyl-N-(p-methylphenylsulphonyl)-N-(pyridin-2-yl)benzene sulphonamide via the ditosylation of 2-aminopyridine. The ditosylated 2-aminopyridine was complexed with Zinc (II) ion and Copper (II) ion. The structural elucidations were achieved through UV–Vis, FTIR, 1HNMR, 13CNMR, ESI-MS and Micro-analysis. The data of the elemental analysis agrees with the molecular masses of ESI-MS. The molar conductance revealed that all the complexes are non-electrolyte in nature. The UV-VIS electronic band of 375–362 nm was assigned to n → π* electronic transition of ligand metal charge transfer (LMCT) of zinc (II) complex while 490–358nm and 690nm were assigned to n → π* electronic transition of ligand metal charge transfer (LMCT) and d→ d to electronic transition of copper (II) complex respectively. The infrared (IR) spectra studies indicated the bond between the ligand and the transition metals. The spectra of the complexes showed an absorption shift, with the free ligand of azomethine having the absorption band of 1689.70 cm-1 while that of the complexes, Zn (II) and Cu(II) have the absorption bands of 1674.27cm-1 and 1651.12cm-1 respectively. The complexation of 4-methyl-N-(p-methylphenylsulphonyl)-N-(pyridin-2-yl)benzene sulphonamide may hopefully increase the biological and catalytic potential of the ligand in the pharmaceutical and chemical industries.","PeriodicalId":18605,"journal":{"name":"Modern Chemistry & Applications","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77148991","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}

Moreover, application of balanced fertilizers and nutrient requirements of the crop is the basis to produce more crop yield from the land under cultivation. Accordingly, field experiment was conducted in 2018 & 2019 main cropping season from the mid of July to first of December at Gedo and Shambu research station to identify the optimum amount of NPS and N fertilizer rate and to evaluate the economic profitability of NPS and N fertilizers for Barley production. The experiment was consisted of twenty treatments combined factorial with five NPS (75, 87.5, 100, 112.5 and 125 kg ha-1) and four Nitrogen (17, 23, 29 and 35 kg ha-1) rates keeping the other managements and cultural practices uniform. The experiment was laid out in randomized complete block design with three replication. The pre soil analysis indicated that the soil of experimental area is acidic (pH = 4.99 at Gedo and 4.98 at shambu) and low in available Phosphorus (12 ppm at Gedo and 13 ppm at Shambu). The main effect of days to heading, grain per spike, thousand seed weight and harvest index were not significantly (P>0.05) influenced due to NPS and N rate. Whereas, days to maturity, plant height and panicle length were significantly different (P<0.05) due to the main effects of N rates though not influenced due to NPS rates at Gedo and Shambu. On the other hand, number of effective tiller, grain yield and above ground biomass were highly significantly (P<0.01) influenced due to the main and interaction effect of NPS and N rates at both locations. Among different NPS and N fertilizer rates tested, the combination of 125 NPS and 35 N kg ha-1 rates gave the highest yield thereby resulting in the highest net benefit. Thus, economic analysis indicated that combination of 125 NPS (47.5 P2O5, 23.75 N, 8.75 S kg ha-1) and 35 N kg ha-1 rates on HB -1307 variety gave grain yield (3631.79 kg ha-1) with the net benefit (39849.01 birr/ha) and the highest marginal rate of return (992.16%) are economically feasible alternative to the other treatments. Therefore it is advisable to use combination of 125 NPS and 35N kg/ha rates on HB -1307 variety since economically feasible to the farmers. However, to reach at conclusive idea there is future line of work to get the peak point at which this fertilizer combination showed turning point.","PeriodicalId":18605,"journal":{"name":"Modern Chemistry & Applications","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84055932","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 menace of these waste plastics in the environment leaves much to be desired. The negative impact of waste plastics in our society cannot be overemphasized. There is need to develop an efficient and cost effective method to manage waste plastics because traditional method such as recycling have been unsuccessful. Some of the disadvantages in recycling include inefficient method of sorting, time consuming, labour intensive, high demand for water and environmental pollution. Therefore, there is need to develop a more efficient and effective method to manage waste plastics. Waste to energy concept through pyrolysis has been identified as a very innovative method of managing these waste plastics. Through research it has been identified that oil from waste plastics through pyrolytic processes tend to have high calorific value and could be used as alternative fuel. This work explored a detailed review on the pyrolytic breakdown of waste plastics through thermal and catalytic degradation and factors that play a critical role in these processes. The end products after pyrolytic breakdown are oil, gaseous materials, and char. The most effective way of controlling the factors for the pyrolytic degradation of the waste plastic that will give optimal fuel production and increase yield for each kilogram of waste plastic was also an area of interest covered in this work.","PeriodicalId":18605,"journal":{"name":"Modern Chemistry & Applications","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73287284","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}

Bioethanol is an attractive, renewable, environment friendly fuel which is considered one of the most promising substitute for fossil fuels. As an agricultural country it produces a large amount of mangoes (Mangifera indica L.) every year. However, Bangladesh is the 8th largest mango producing country in the world. The aim of this research was to find out the potentiality of bioethanol production from different over-ripen mango varieties of Bangladesh. About 100 g of sample mango pulp was blended with 300 ml of distilled water and then sterilized. For fermentation, 200 ml (1x105 cell/mL) 24-hours old yeast culture (Saccharomyces cerevisiae) was added to make the total volume 500 ml and incubated at 35°C for 6-days. Five different local mango varieties (Lengra, Khershapat, Amropali, Fazli and Lakhna) were assessed for bioethanol production. Out of these mango varieties a highest yield and purity of bioethanol was found in Khershapat (Mangifera indica L.) 77.67 g/L with 32% (v/v) purity. This research proved that Bangladesh has a good opportunity of bioethanol production from over-ripen mangoes.","PeriodicalId":18605,"journal":{"name":"Modern Chemistry & Applications","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85438164","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}

Epoxy-based compositions were prepared and their properties were studied using various fillers. For this purpose, polyethylene polyamine ED-20 brand epoxy oligomer and its hardener were used. In scientific research, the effect of various fillers on the properties of epoxy resin has been studied experimentally. The dependence of the composition of the insoluble part of ENO on the drying time at a temperature of 110°C - 150°C was determined. It was found that the inclusion of fillers in the composite material greatly affects the mechanical properties. Thus, in a certain mass fraction of kaolin and eggshell powder, the adhesion strength increased, but the subsequent increase in the amount of fillers decreased. In general, it can be noted that the tensile strength of unmodified epoxy resin is higher than the strength of epoxy compositions, and the modulus of elasticity is lower. This indicates that the addition of filler to the epoxy resin and glass / epoxy resin reduced the tensile strength and increased the modulus of elasticity. The result allows the buoy to be used in industry.","PeriodicalId":18605,"journal":{"name":"Modern Chemistry & Applications","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79036104","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}
