Abstract Symmetrical gemini surfactants of cationic series α,ω‐alkanediyl bis (dimethyl ammonium bromide) commonly referred as “ m – s ” have been synthesized. Spectral analysis was performed to confirm compound structures and purity. Conductivity surface tension measurements provide better understanding the micellization process. Their self‐assembly behavior in aqueous solution is also discussed detail. The antimicrobial efficacy measured by bacterial fungal growth inhibition expressed...
Fulminant myocarditis is a severe form of acute myocarditis, characterized by complications such as hemodynamic compromise, often requiring advanced mechanical support. It can occur result infection, toxin exposure, or autoimmune processes. This case 53-year-old male with no past medical history who presented one week fever, shortness breath, and upper respiratory symptoms subsequently developed fulminant left ventricular dysfunction cardiogenic shock both inotropic Initial serological...

Tok become platform portrayal talent youngsters adding meaning to already existing platforms. It is fastest growing fascinated engrossed so many across globe one fastest-growing India. basically alternative version online sharing, that allows its users interface preparing short videos music pieces. obsession among giving them express innovatively ingeniously....
A series of new quinazolinone based mono azo reactive dyes (D1–10) have been prepared by subsequent diazotization 2-phenyl-3-[4′-(4″-aminophenylsulphonamido)]phenyl-4(3H)-quinazolinone-6-sulphonic acid (C) and coupling with various 4-chloro anilino cyanurated components. These give purple, red, orange yellow color shades. All the were characterized their percentage yield, UV–Vis spectroscopy, elemental analysis, IR 1H NMR spectroscopy dyeing performance on silk, wool cotton fibres. The dye...
Ten new monoazo disperse dyes (4a–j) have been synthesized by coupling of diazotized 2-amino-4-(2′,4′-dichlorophenyl)-1,3 thiazole (2) with various N-alkyl derivatives substituted aniline (3a–j) and their dyeing performance on polyester fiber has assessed. These are characterized elemental analysis, UV–vis spectra, IR NMR spectroscopy. The absorption maxima (λmax) were recorded in DMF found to be the range 530–600 nm. dyed fabric showed fair very good light fastness excellent washing rubbing...
High-performance polymers based on aromatic rings are desirable not only because of the high primary bond strengths, but also their rigid (stiff) polymer chains offer increased resistance to deformation and thermal softening. The choice s-triazine nucleus is its stability derived from molecular symmetry aromaticity. It well known that heat resistant. Modification monomer structures by introduction pendent groups or heterocyclic into backbone provides good solubility stability. A new set...
4,4′-Methylene-bis-metanilic acid (A) was synthesized by the reaction between metanilic and formaldehyde. The compound used as a bifunctional middle component in preparation of several symmetrical hot brand bis azo reactive dyes. tetrazotized coupled with various m-nitro anilino cyanurated coupling to give entired compounds have been identified IR, 1H NMR spectra elemental analysis. dyes were applied on silk, wool cotton fabrics their fastness properties evaluated. All good properties....
A series of cold brand bisazo reactive dyes (4a–h) were obtained by the coupling tetrazotised 4,4′-methylene-bis(2-methyl-5-nitro aniline) (2) with various cyanurated components (3a–h) in good yield. Their dyeing performances as have been assessed on silk, wool and cotton fabrics. These characterized UV–Vis, FTIR, 1H NMR spectroscopic techniques elemental analysis. The percentage dye bath exhaustion fixation different fibers found to be very good. dyed fabric showed moderate light fastness...
A series of some new quinazolinone based MCT reactive dyes (7a–j) were successfully and easily synthesized by the coupling route diazotized 3-{4-[4-amino-2, 6-difluorobenzyl]-3,5-difluorophenyl}-6-nitro-2-phenylquinazolin-4(3H)-one (4) with a diverse range o-chloro-p-nitro anilino cyanurated components (6a–j). The structures all confirmed UV–Vis, IR, 1H 13C NMR spectroscopies. All newly tested for their in vitro antimicrobial screening (antibacterial antifungal) against several bacteria...
The aim of this investigation is to present the synthesis and characterization some 3,3′-(methylenedi-1,4-phenylene)bis(4-substituted aminosulfonyl)sydnone (7a–j) evaluate their antimicrobial activity. All newly synthesized compounds were characterized by spectral data as well elemental analysis. Some showed excellent activity against Gram-positive Gram-negative bacteria.
An extensive characterization study on the novel series of synthesized sydnone, chalcone and pyrimidine is reported in this paper. A 3-(4-chlorophenyl)-4-{[4-(3-substitutedphenylacryloyl)phenyl]sulfamoyl}-sydnone 3-(4-chlorophenyl)-4-[4-(4-aminophenyl)-6-substitutedphenylpyrimidin-2-aminesulfonyl]-sydnone are synthesized. The structures compounds were characterized by elemental analysis, IR, 1H NMR, 13C NMR mass spectroscopy. exclusive microbial activity using various strains was also...
