Interaction between tetradecyltrimethylammonium bromide and benzyldimethylhexadecylammonium chloride in aqueous/urea solution at various temperatures: An experimental and theoretical investigation

The mixed micelle formation between tetradecyltrimethylammonium bromide (TTAB) and benzyldimethylhexadecylammonium chloride (BDHAC) has been investigated in the absence as well as attendance of urea using conductivity technique. The evaluated values were examined in accordance with Rubingh model. The obtained values of critical micelle concentration (cmc) were smaller than cmcid values suggesting attractive interactions between the constituents of solution. The micellar mole fractions (X1Rub) of BDHAC, estimated by Rubingh model, were always higher than their ideal values (X1id) suggesting the high contributions of BDHAC in mixtures of TTAB and BDHAC. Interaction parameter (beta) value was found to be negative showing an attractive interaction between the studied components. Activity coefficients (f1Rub and f2Rub) were always smaller than one in all cases and it indicates the attractive interaction between TTAB and BDHAC. The values of DeltaGmo are found to be negative in all the cases which indicate the spontaneous formation of micelle. The values of DeltaH0m are negative in all cases indicating the exothermic process. The values of DeltaS0m are positive in case of aqueous medium and 500?mmol¡¤kg??1 urea solutions but found to be negative in attendance of 1000?mmol¡¤kg??1 urea. The values of excess free energy of micellization (DeltaGexRub) were also estimated and achieved to be negative showing the stability of mixed micelles.

Final Thoughts on Chemistry for 15862-18-7

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 15862-18-7, help many people in the next few years.15862-18-7

15862-18-7, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.15862-18-7, Name is 5,5′-Dibromo-2,2′-bipyridine, molecular formula is C10H6Br2N2, introducing its new discovery.

Development of fluorescent film sensors based on electropolymerization for iron(III) ion detection

Two electroactive materials, M1 and M2, are synthesized and their fluorescent electropolymerized (EP) films are prepared and used to detect metal ions. From the tested metal ions, M1 and M2 are demonstrated to be sensitive and selective for Fe3+ ions. In particular, M2 exhibits higher sensitivity towards Fe3+ ions. The fluorescent detection ranges from 10-5M to 4¡Á10-4M. The excellent performance of the EP fluorescent films is mainly due to the strong metal-chelated properties of M2 and the intrinsic porous cross-linked-network microstructure of the EP films. This study, thus, provides a promising Fe3+ sensing candidate and a potential preparation method for fluorescent sensing films. Film sensors: Two films made by electropolymerization of electroactive compounds with different metal-chelation sites are made and shown to be highly sensitive and selective fluorescent sensors for Fe3+ ions (see figure; ITO= indium tin oxide).

Turpentine valorization by its oxyfunctionalization to nopol through heterogeneous catalysis

Turpentine is a mixture of monoterpene hydrocarbons obtained as a by-product in the paper industry. In this contribution we present its transformation process towards an alcohol named nopol, that is an important household product and fragrance raw material. Reaction conditions were established for the oxyfuntionalization of crude turpentine oil over Sn-MCM-41 catalyst for the selective conversion of beta-pinene to nopol. Synthesized materials were characterized by XRD, N2 adsorption, FT-IR, TEM and chemical absorption. The reaction was tested in 2 mL glass reactor with a sample of commercial turpentine with alpha-pinene (55.5% w/w) and beta-pinene (39.5% w/w) as main components and scaled up into a 100 mL Parr reactor, getting 92% conversion of beta-pinene and a nopol selectivity of 93%. The reusability tests showed that the catalyst can be reused 4 times without loss of activity. The results showed that 86% less solvent and 37.5% less paraformaldehyde can be used with turpentine, compared to the conditions used with beta-pinene for getting similar catalysts activity.

Facile Synthesis of Concave Cuboid Au NCs with Precisely Tunable Dimensions and Mechanistic Insight

Concave cuboid (CCB) nanostructure is a member of the high-index facet (HIF) nanocrystals (NCs) family, geometrically derived from regular cuboid-excavation of each face. CCB NCs hold some additional characteristics such as surface cavity and sharp edges and corners as compared to its convex counterpart that makes it relatively more active in applications like electrochemical catalysis, surface enhanced Raman spectroscopy (SERS), and plasmonics. To date, there are only few reports available on the synthesis of CCB Au NCs where Br- containing surfactants have been used as a shape directing and stabilizing agent. However, none of them led to decent yield and size tunability. Herein, we report a robust seed mediated growth strategy where cetyltrimethylammonium chloride (CTAC) and tannic acid (TA) have been used as shape-directing/stabilizing and mild reducing agents, respectively. Our method not only allows the high yield fabrication of CCB Au NCs with uniform shape and size but also precise control over dimensions and degree of surface concavity. Moreover, the investigation of growth mechanism revealed that the evolution of CCB Au NCs from cylindrical nanorods (NRs) take place via arrow-headed nanorods and truncated CCB nanostructures. Furthermore, it has been observed that the presence of excess of Cl- is indeed playing a decisive role despite the headgroup of counter cationic part of surfactant. We anticipate that our findings may pave the path to design new synthetic strategies and understand the evolution of new nanostructures.
