Flavone scaffold is one of the most often perceived parts in biologically active organic compounds. In light of this, a flavone; 2-(4-fluorophenyl)-4H-chromen-4-one (FPC) has been synthesized, characterized and studied by using density functional theory (DFT) at B3LYP/6-31G(d,p) basis set. The geometry of the FPC molecules has been optimized by using B3LYP/6-31G(d,p) basis set and in-depth structural analysis on bond lengths and bond angles has been discussed. The HOMO-LUMO analysis and various quantum chemical parameters are computed and discussed for the better understanding of chemical behaviour of the title molecule. Molecular electrostatic potential (MEP) surface investigation is presented to understand the reactivity sites of the title molecule.

Present investigation deals with the synthesis and density functional theory study (DFT) of a Biginelli adduct; 6-methyl-2-oxo-4-phenyl-1,2,3,4-tetrahydropyrimidine-5-carboxylate (MOPTHPC). The synthesis of a MOPTHPC has been carried out by the reaction of benzaldehyde, ethyl acetoacetate and urea in ethanol 70-80 ℃ under stirring condition in presence of catalytic amount of sulfamic acid. The structure of a synthesized chalcone is affirmed on the basis of 1H NMR and 13C NMR. The geometry of a MOPTHPC is optimized by using the density functional theory method at the B3LYP/6-311G(d,p) basis set. The optimized geometrical parameters like bond length and bond angles have been computed. Quantum chemical parameters have been determined and examined. Molecular electrostatic surface potential (MESP) surface plot analysis has been carried out at the same level of theory. Mulliken atomic charge study is also discussed in the present study.

Article history: Received 16 February 2021 Accepted 08 March 2021 Available online 04 April 2021 The vital physical characteristics of aggregates used in engineering and for interpretation of the genesis of naturally occurring sediment are shape and size of rocks. The mineralogical and physical composition of the rock is necessary to cater to the interaction within bounded space and soundings. Several image processing programs are available to measure the size and shape of various types of objects. The accuracy and reproducibility of the results of these imaging methods could be bettered. This paper aims to determine the aggregate dimension and volume to space behaviors through image processing tools. This study is extended investigation of the coarse aggregate shape properties such as area, volume, center of gravity (CG), elongation and flakiness index. Also, this paper discuss the development of an easy to use image processing tool to determine the shrinkage of soils due to lack of moisture content either because of natural ways/artificial ways. Two different types of soils including first sample near the SNU lake and second sample near Business Management School at Shiv Nadar University (SNU), India were collected. The samples were oven-dried over a period and shrinkage values were determined by Digital Image Processing (DIP) using MATLAB. The results are compared to wax-water method (manual method) results of shrinkage. The properties found by DIP method are reasonably agreeable for multiple aggregates and minor percentage differences in the soil shrinkage results.

Twenty-five authentic samples of Prunus amygdalus gum samples were collected from five different locations in northwest of Libya. Different physicochemical methods were used to characterize this type of gum samples. The mean values of the moisture ranged from 12.55 to 14.93%, ash mean values 4.03 to 4.62%, pH 3.89 to 4.40, W.H.C 52.85 to 60.0%, and O.H.C 136.2 to 156.3%. Solubility of Prunus amygdalus gum showed that it had low solubility in distilled water with the mean values ranged from 20.01 to 35.40%, but it dissolved perfectly in alkali media where solubility increased to 96.3% in 0.05 M Na2CO3. The study exhibited that the mean values of cationic concentration in %(w/w) such as calcium was ranged from 0.552 to 0.585, potassium 0.402 to 0.505, iron 0.0975 to 0.1125, and sodium 0.064 to 0.079, which indicates that Ca has the highest concentration of metallic ions present. Atomic absorption method indicate that all samples contain traces of elements, Li, Cr, Mn, Ni, Zn, Pb, Hg, and Cd. The main functional groups recorded from FTIR spectrum included bands at 3293 cm-1 (O-H in carboxylic group), 1601.77 cm-1 (C=O, amide N-H bend, and C=C), 1357.53 cm-1 (CH3-, and C-O-H in- plane bending vibration), and 1025.74 cm-1 (C-O stretching).

The composition, properties, structure and morphology of electrodeposited Zn-Fe alloy deposits obtained from an acid sulphate bath containing triethanolamine have been investigated. A bath containing less zinc (20%) produced an alloy deposit with higher zinc content (80%), i.e. anomalous co-deposition process. The composition of alloy remained constant with pH of the plating bath and thickness of the alloy deposit. The cathodic current efficiency depends on plating variables. The shift in deposition potentials of Zn-Fe alloy is a chief cause in the co-deposition process to produce alloy of varying composition. Phase structure determination by X-ray diffraction studies showed a wide variety of inter metallic phases. Zn-Fe alloy showed a superior corrosion resistance than zinc coatings. An alloy containing greater than 40% Fe showed a good paintability. Hardness of the alloy deposits increased with increase in iron content in the alloy. Smooth, uniform and fine grained deposits were obtained for the Zn-Fe alloy containing 20% Fe.

This work reports synthesize of polypyrrole nano powder by chemical in-situ polymerization of pyrrole in aqueous solution and ammonium persulfate solution which acts as oxidant. It is characterized by X-ray diffraction (XRD), Fourier infra-red spectroscopy (FTIR) and scanning electron microscopy (SEM). The XRD spectrum reveals that the materials are amorphous in nature. FTIR analysis confirms that all peaks are the main characteristic of PPy. SEM analysis showed that the powder has a uniform granular morphology and the size varies from ∼500 nm to 1 μm. The micrograph of polypyrrole reveals the presence of globular particles. The formed particles are irregular in nature. The results show that the fibers are chemically formed as spherical nanostructures.

Removal of malachite green from water bodies is an environmental concern of utmost priority. It requires adsorbents that can efficiently operate under real conditions. In view of this, a new polyacrylic acid based nano-hybrid polymer was synthesized by using sol-gel method in which acrylic acid acts as an organic part and tetraethoxysilane (TEOS) as an inorganic component. The new series of two other nano-hybrid polymers were also synthesized by using nanoparticles of iron oxide and titanium dioxide. The synthesized nano-hybrid polymers were extensively characterized using FTIR and XRD spectroscopic techniques. Further the synthesized nano-hybrid polymers were subjected to swelling studies with respect to different parameter such as time, temperature and pH. Malachite green was used as a cationic dye for studying the uptake behavior of synthesized polymers. Maximum retention capacity (MRC) and reusability of hybrid polymers were also evaluated up to ten cycles. The hybrid polymer, poly(AAc)/TEOS was more effective with high dye retention capacity.

It requires adsorbents that can efficiently operate under real conditions. In view of this, a new polyacrylic acid based nano-hybrid polymer was synthesized by using sol-gel method in which acrylic acid acts as an organic part and tetraethoxysilane (TEOS) as an inorganic component. The new series of two other nano-hybrid polymers were also synthesized by using nanoparticles of iron oxide and titanium dioxide. The synthesized nano-hybrid polymers were extensively characterized using FTIR and XRD spectroscopic techniques. Further the synthesized nano-hybrid polymers were subjected to swelling studies with respect to different parameter such as time, temperature and pH. Malachite green was used as a cationic dye for studying the uptake behavior of synthesized polymers. Maximum retention capacity (MRC) and reusability of hybrid polymers were also evaluated up to ten cycles. The hybrid polymer, poly(AAc)/TEOS was more effective with high dye retention capacity.","PeriodicalId":14902,"journal":{"name":"Journal of Advanced Chemical Sciences","volume":"48 1","pages":"682-685"},"PeriodicalIF":0.0,"publicationDate":"2020-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85254779","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}
