In this Letter, we show that the shape of a freezing drop of water can be sensitive to the presence of impurities. We measure the tip angle of water drops frozen on a cold plate. The fine changes in the tip angle are robustly captured by our image analysis method, which shows a deviation from that of pure water in solutions with salt (NaCl), polymer polyethylene glycol, and surfactant tetradecyltrimethylammonium bromide starting at concentrations of 10 – 6, 10 – 4, and 10 – 6 M, respectively. The method could be adapted into a portable water purity tester, but this work also highlights the complexity of water freezing as it is influenced by trace concentrations of impurities.

In principle electroseparation methods are well suited for the analysis of relatively polar compounds such as underivatized amino acids. These systems provide several benefits such as high performance, the possibility of miniaturization and integration and low cost of analysis. The absence of a derivatization step implicates additional advantages like the avoidance of all types of pitfalls related to this procedure. Unfortunately the analysis of amino acids in their underivatized form also generates some new problems such as the necessity to separate compounds with very similar structures and the need to find detection systems providing sufficient sensitivity for these compounds. The capillary electroseparation method most commonly employed for underivatized amino acids is capillary zone electrophoresis and up to now a substantial number of reports describing the application of this technique for a wide range of different samples can be found. Optimized procedures allowing the separation of the whole set of protein amino acids in a single run have been developed. Detection is mostly performed using either spectrophotometric detectors (mainly because of their presence in most commercially available instruments) or electrochemical detection. Although substantial efforts to improve its sensitivity for underivatized amino acids have been made, spectrophototmetric detection can not be regarded as the best choice for this type of analytes. Electrochemical detection in particular the more recently presented contactless conductivity detector provides better performance. Optimum choice for the detection of underivatized amino acids after their separation using capillary electrophoretic or electrochromatographic methods is the use of a mass spectrometric detector. This can also be seen from the increasing number of publications dealing with this issue.

The adsolubilization of the cationic dye rhodamine B (RB) into the adsorbed layers of dodecyl- (DTAB) and tetradecyltrimethylammonium bromide (TTAB) on high silica mordenites (HSZ-1, HSZ-3) and P-type zeolite (PZ) was examined quantitatively. The adsolubilization constant for the HSZ-1/TTAB system was determined at temperatures from 10 to 40 C. As the surfactant adsorption increased, the adsolubilization of RB by the zeolite/surfactant complexes was enhanced. Adsolubilization of RB by HSZ-3/surfactant complexes required a critical quantity of adsorbed surfactant, whereas the PZ/TTAB complex needed only a very small quantity of adsorbed TTAB to adsolubilize RB. Both the adsolubilization constant and the maximum capacity were calculated using a Langmuir-type equation, and the enthalpy and entropy changes were determined for the HSZ-1/TTAB mixed system. The difference in the adsolubilization mode of the three zeolite/surfactant complexes is discussed in relation to the aggregation mode of the cationic surfactant.

The effect of the type and the concentration of ionic surfactants on the electric charge on small silicone oil droplets is studied by using an electrical suspension method. The adsorption process of a cationic surfactant, cetyltrimethylammonium bromide (CTAB), is characterized by gradual neutralization of the negative charge on the oil-in-water (O/W) emulsion droplets at low surfactant concentrations. As the surfactant concentration increases, the adsorption process leads to the charge reversal. The point of charge reversal (pcr) occurs approximately at 2.5 x 10-6 M CTAB. Further increasing the surfactant concentration causes an increase in the positive charge and eventually results in the maximum positive charge on the oil droplets near the critical micelle concentration (CMC) of CTAB. The limited charge reflects the saturation of the adsorption of surfactant molecules on the oil-water interface. In an anionic surfactant solution of sodium dodecyl sulphate (SDs), however, the silicone oil droplets are all negatively charged and the negative charge increases with increasing the surfactant concentration. The saturation state is also observed for the anionic surfactant adsorption. The maximum negative charge is achieved when SDs concentration approaches its CMC. In addition, two types of ionic adsorption onto the oil-water interface may occur for NaCl electrolyte solutions containing either CTAB or SDS: the surfactant adsorption and the electrolyte adsorption, although the former is much stronger than the latter. At constant surfactant concentration, their cooperation strengthens the charge at lower NaCl concentrations and leads to the strongest charge at some concentration. However, their competition at higher NaCl concentrations reduces the charge on the oil droplets.

The zeta potential of cellulose nanocrystal (CNC) aqueous dispersions was studied as a function of solution conditions, including changing pH and different electrolyte identities and concentrations. A range of electrolytes that spans typical Hofmeister/hydrophobic effects was explored, along with both cationic and anionic surfactants. A subtle interplay of electrostatic and hydrophobic effects in ion adsorption was uncovered, including evidence of charge reversal and supercharging when hydrophobic surfactants are added to aqueous CNC dispersions. The apparent effects of zeta potential on dispersion stability were explored by using atomic force microscopy (AFM) to determine the roughness of resulting CNC films. The root mean square roughness (RMS) of these cellulose films was unaffected by the presence of surfactants (achieving a constant value of ?9 nm), but scaled inversely and non-linearly with the zeta potential of the CNC suspension while using the ionic salts from ?2 nm to 10 nm, indicating a facile method for the control of cellulose film roughness.

Nanoengineering a library of metallic nanostructures using a single microfluidic reactor

Microfluidic synthesis in a microfabricated reactor enables fast and facile synthesis of a wide library of metallic nanostructures: monometallic, bimetallic, anisotropic growth and heterostructures. Specific nanostructures are realized by selection of flow pattern and synthesis parameters. The technique is shown to have advantages over conventional batch technologies. Not only does it allow faster scalable synthesis, but also realization of nanostructures hitherto not reported such as Pt-Ru, Pt-Ni and Pt-Co nanodendrites, Pt-Pd heterostructures, Ag-Pd core-shell NPs, Au-Pd nanodumbbells and Au-Pd nanosheets.

Electrical characterization of the polyaniline/p-silicon and polyaniline titanium dioxide tetradecyltrimethylammonium bromide /p-silicon heterojunctions

Au/PANI/p-Si/Al and Au/PANI TiO2 TTAB/p-Si/Al heterojunctions have been fabricated by spin coating of soluble polyaniline (PANI) and PANI titanium dioxide (TiO2) tetradecyltrimethylammonium bromide (TTAB) on the chemically cleaned p-Si substrates. The thicknesses of the polymeric films have been determined by a profilometer. The current-voltage (I-V) characteristics of the heterojunctions have been obtained in the temperature range of 98-258 K. These devices have showed the rectifying behavior such as diode. The I-V characteristics of the devices have been analyzed on the basis of the standard thermionic emission theory at low forward bias voltage regime. It has been shown that the values of ideality factor decrease while the values of barrier height increase with increasing temperature. This temperature dependence has been attributed to the presence of barrier inhomogeneities at the organic/inorganic semiconductor interface. Furthermore, analysis of the double logarithmic I-V plots at higher forward bias voltages at all temperatures indicates that transport through the organic thin film is explained by a space-charge-limited current process characterized by exponential distribution of traps within the band gap of the organic film. The total concentration of traps has been found to be 3.52 × 1014 cm- 3 and 3.14 × 1015 cm- 3 for PANI and PANI TiO2 TTAB layer, respectively.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 1119-97-7, you can also check out more blogs about1119-97-7

The biodegradation of monomeric and dimeric alkylammonium surfactants

Quaternary ammonium compounds (QACs) are salts known for having antiseptic and disinfectant properties. These compounds are toxic to aquatic organisms and should thus be removed from wastewater before its discharge into surface waters. The biodegradation of QACs takes place in the presence of microorganisms under aerobic conditions. The susceptibility of these compounds to degradation depends on numerous parameters. A number of them, such as the structure-adsorption on solids, and concentration of the QACs, as well as the presence of additional substances, have been reviewed in this article. Moreover, the biodegradability of new dimeric alkylammonium salts, i.e., cationic gemini surfactants, has been discussed and compared with that of anionic and nonionic geminis. The biodegradation study of monomeric and dimeric alkylammonium surfactants show that they are not easily degraded. The degradation process is very complex and strongly depends on the structure of the compound, adsorption-desorption processes on sludge, type of microorganism consortia and the presence of anions. Alkylammonium surfactants with biological motifs, like amide, peptides or carbohydrates, are much better degraded.

Evidence of positive co-operativity in the micellar catalysis electron transfer reaction

Microenvironments consisting of surfactants are capable of either inhibiting or catalyzing the reaction rate depending on the specific interaction between surfactant and the reactant species. In this context, micellar catalyzed electron transfer reaction between methylene blue (MB) and ascorbic acid (AA) have been studied in presence of three cationic surfactants (TTAB, CTAB & CPC) at different temperatures under pseudo-first order condition. The kinetic data have been analyzed with different models (i.e., pseudo-phase model, Piszkiewicz’s model and Raghavan-Srinivasan’s model). The micellar binding constant evaluated from the three models are in good agreement with each other. Out of three surfactants, the lower standard enthalpy of activation (??H) and higher negative standard entropy of activation (??S) of CPC have been ascribed to the planar structure of the pyridinium head group which provides less steric hindrance to the attacking ascorbate ions. The formation of catalytic sub micellar aggregates between dye and micelle in the reaction medium in a ratio of 1:1 and 1:2 have been well justified by TEM measurements and the result of positive co-operative values. The catalytic activity of surfactants as well as micellar binding constant increases in the following order: CPC > CTAB > TTAB.

9-Acridinemethanamine and Acridine-9-Carboxaldehyde as Potential Fluorescence Lifetime pH Indicators

A significant challenge concerning the development of fluorescence lifetime (FL) based pH sensors is the paucity of fluorophores with sufficiently large FL variation with pH. Acridine is amongst the indicators with highest fluoresce lifetime responses to pH, with a change in lifetime of about 13 ns within a pH range of 5?8. Here we examine the two acridine derivatives, 9-acridinemethanamine (9-AMA) and acridine-9-carbaldehyde (9-ACA) in terms of their FL pH sensitivity and pH sensing range. Both indicators are characterized when dissolved in buffer solutions, as well as when immobilized in support materials. 9-AMA has a change in FL of 11 ns between pH 2?5, both when dissolved in solution and when immobilized in surfactant-filled mesoporous silica. The FL of 9-ACA is not sensitive to pH when dissolved in buffer solutions; however, when covalently bound to amine-modified silica, its FL changes 15 ns between pH 3?6. 9-AMA and 9-ACA represent promising FL in the pH range of pH 2?6, and could potentially form the basis of new FL pH sensors.
