Anionic phosphate gemini surfactants

Gemini surfactants are a new class of surfactants. They are made up of two identical or different amphiphiles moieties having the structure of conventional (monomeric) surfactants connected by a spacer group. Geminis are known for their superior properties such as the low critical micelle concentration (cmc), high efficiency of reducing the surface tension of water, and micelle structural characteristics. Anionic geminis are further sub classified into four types i.e. sulphate, sulphonate, carboxylate and phosphate. Phosphate gemini surfactants are a class of gemini surfactants. Phosphate esters represent specialty surfactants fitting a number of niche markets. The phosphate gemini surfactants found application as antistatic agents, emulsifiers, wetting agents, and hydrotropes. The aim of this book is to provide up to date information on synthesis and characterization of higher fatty alcohols based anionic phosphate gemini surfactants. Physicochemical and surface active properties of synthesized anionic phosphate gemini surfactants have been studied thoroughly.

Studies on Surfactant-Additive Systems

Nowadays considerable research has been carried out on a new type of surfactants called as gemini surfactants, using variety of experimental methods. By far the most studied of gemini surfactants are cationic gemini, m-s-m (N, N?-bis(alkyldimethyl)-?, ?-alkanediammonium dibromide type) type surfactant. In particular, the choice of cationic gemini surfactants was made in an effort because of the low toxicity of quaternary ammonium surfactants as well as low critical micelle concentration. In addition to low toxicity, quaternary ammonium surfactants exhibit broad spectrum of antimicrobial activity including antibacterial, antifungal and antiviral. Gemini surfactants may be an appropriate alternative to traditional quaternary ammonium compounds. The geminis used in the present studies, though extensively studied, still lack a quantitative interpretation of their mixed micellar behaviour with the conventional surfactants. Therefore, a thorough investigation and relative comparison among the mixed micellar properties with the conventional surfactants would allow their appropriate applications to achieve both fundamental as well as applied goals.

Interaction of metal-ions and surfactants with proteins

This research work is based on the studies on the binding of soluble ovalbumin, transfusion gelatin, ?-amylase proteins with vanadium and molybdenum etc. applying various physico-chemical methods such as pH-metery, dialysis equilibrium, spectrophotometry, polarography etc. The work also includes the binding of metal hydrous oxide sols to these proteins. The effect of anionic surfactants like triethanolamine lauryl sulphate, sodium dodecyl benzene sulphonate was also studied on ovalbumin casein and ?-amylase by viscometric and other related methods. The binding results are helpful in proposing a mechanism of ligand interaction with biopolymers in livings mediated by metal ions. The additions of proteins may decrease the critical micelle concentrations of the surfactants. This aspect possesses a good means of increasing the detergency of the surfactants.
Association of Anionic Surfactant with Ethyl(hydroxyethyl) Cellulose Association of Anionic Surfactant with Ethyl(hydroxyethyl) Cellulose Новинка

Association of Anionic Surfactant with Ethyl(hydroxyethyl) Cellulose

This book reports the interactions between the non-ionic polymer of ethyl(hydroxyethyl)cellulose (EHEC) and mixed anionic surfactant sodium dodecanoate (SDoD)-sodium, decanoate (SDeC) and sodium dodecyl sulfate (SDS) in aqueous media, at pH 9.2 (20 mM borate/NaOH buffer) were investigated by surface tension, electric conductivity and light transmittance measurements at 25 ?C. Some aspects of ethyl(hydroxyethyl)cellulose (EHEC) aqueous behavior in the presence of ionic surfactants are described in the literature; however, most of the studies reported deal with moderately concentrated solutions. Few studies have been carried out in the dilute regime using mixtures of anionic surfactants. The main proposal of this work is to investigate the interaction of EHEC in diluted regime and to verify the mixtures of the surfactants SDS, SDoD and SDeC. Through the results was not observed a specific link of polymer with the surfactant, implying therefore a phenomenon only cooperative association.

Characteristic Features of Dendrimers in Aqueous Micellar Solutions

Our work suggests that dendritic macromolecules studied herein exist in the form of aggregated self-assembled structures in aqueous phase and these aggregates have been clearly viewed by surface topography. In the presence of ionic surfactants, the macromolecules show significant interactions both with the monomeric and micellar species due to the electrostatic interactions, which become more clearer under the pH effect. The cationic surfactants show strong electrostatic interactions in the basic medium, while anionic surfactants demonstrate this behavior in the acidic medium. The nature of head group as well as counter ion demonstrates a clear influence on the magnitude of dendrimer-surfactant interactions. The cationic surfactant with dimeric nature and bromide counter ion demonstrate much stronger interactions with both amine and ester terminated generations of PAMAM.

Cationic Surfactants as Corrosion Inhibitors under H2S environment

The use of chemical inhibitors to decrease the rate of corrosion processes is quite varied. In the oil extraction and processing industries, inhibitors have always been considered to be the first line of defense against corrosion. A great number of scientific studies have been devoted to the subject of corrosion inhibitors.Cationic surfactants represent only 5-6% of the total surfactant production. However they are extremely useful for some specific uses, because of their peculiar properties .They are not good detergents nor foaming agents, and they cannot be mixed in formulations which contain anionic surfactants
Imidazoline surfactants derived from diethylenetriamine & fatty acids Imidazoline surfactants derived from diethylenetriamine & fatty acids Новинка

Imidazoline surfactants derived from diethylenetriamine & fatty acids

The conventional thermal methods used for synthesis of imidazolines suffer from many disadvantages such as long reaction times, low yield of products and tedious work up. To overcome the above disadvantages microwave assisted synthesis of imidazolines is, therefore gaining momentum as an alternative method to conventional methods. The aim of the book is to provide latest information about microwave synthesis and characterization of diethylene triamine based imidazoline surfactants derived from renewable fatty feed stocks. The surface active and performance properties of various imidazoline surfactants have been studied. Besides this, laundry applications of these surfactants in combination with suitable non-ionic surfactants have also been stressed. Furthermore, development of cost - effective imidazoline surfactants has also been explored.

Magnesium phosphate cements for clinical applications Magnesium phosphate cements for clinical applications Новинка

Magnesium phosphate cements for clinical applications

A family of magnesium phosphate cements was explored as candidate biomaterials for hard tissue applications. These cements were prepared by mixing magnesium oxide with either sodium dihydrogen phosphate, ammonium dihydrogen phosphate or an equimolar mixture of both. The exothermia and the setting kinetics of the cement formulations were tailored. The ammonium-containing magnesium phosphate cements resulted in struvite, whereas the cement prepared with sodium dihydrogen phosphate resulted in an amorphous product. The magnesium phosphate cements studied had an early compressive strength and antimicrobial properties. These properties make magnesium phosphate cements good candidates for endodontic applications. It is with this latter point in mind that their radiopacity was enhanced. The sealing efficiency of the magnesium phosphate cements and their adhesion to dentin were shown to be comparable or even higher than those presented by other inorganic cements used for endodontic treatments.

Phosphate-deficiency response: Phosphate-deficiency response: Новинка

Phosphate-deficiency response:

Phosphate sensing and signaling allow plants to adapt to phosphate availability. However the knowledge about the transduction pathway that integrates phosphate deficiency responses to adjust growth to match resources is patchy. Here it is presented a genetic screen for conditional mutants aiming to dissect the signaling of phosphate deficiency. Two mutant lines, pdr1 and pdr2 are characterized. Steady-state mRNA levels of multiple Pi-starvation-incucible genes are reduced in pdr1 plants. Its cytokinin sensitivity is altered and its short root phenotype is rescued by the omission of nitrate in high phosphate. The second mutant, pdr2, show a determined meristem growth dependent on the local phosphate availability. We hypothesize that PDR1 is involved in P-N crosstalk and PDR2 is required for maintaining primary root cell division in low P. Recent advances in phosphate signaling are discussed.

Mature Municipal Landfill Leachate Treatment: Ion Exchange Practice Mature Municipal Landfill Leachate Treatment: Ion Exchange Practice Новинка

Mature Municipal Landfill Leachate Treatment: Ion Exchange Practice

Mature leachate generated from an aged sanitary landfill is typically classified as non-biodegradable.Disposal of untreated landfill leachate can be a source of hazard to receiving waters. Therfore, treatment of landfill leachate is considered environmentally essential. The application of ion exchange process in landfill leachate treatment was not well established in literature. Optimized operational conditions and the interaction among process variables for this treatment process were unidentified, leaving a substantial gap in landfill leachate treatment knowledge. In the present work, the treatment of mature landfill leachate using vriouse ion exchange process ssuch as cationic resin, anionic resin only, cationic followed by anionic (cationic-anionic), and anionic followed by cationic (anionic-cationic) were established and documented for the first time.

Effects of airborne surfactants on the coastal forest Effects of airborne surfactants on the coastal forest Новинка

Effects of airborne surfactants on the coastal forest

Under natural conditions, the plants are subjected to multiple environmental stresses and to interaction between those. The simultaneous action of several stresses could be very complex, and the plants response is unpredictable, due to the overlapping or antagonistic effects. Linear Alkylbenzene Sulfonates (LAS) are a group of synthetic anionic surfactants widely used in the composition of household or industrial detergents and agrochemicals. Even though these molecules are readily biodegradable, they have been reported as contaminants of different environmental compartments. This research was designed to understand the actual contribution of LAS to the decline of Mediterranean coastal forest exposed to marine aerosols contaminated with surfactants. Therefore, of key importance was to unravel the particular mechanism of synergistic action of the LAS and marine salts in order to predict the effects on the plants health status, among other factors. This work addresses to both academic and industry professionals in the field of environmental risk assessment.
