In this study, a new ferrocenyldithiophosphonate functionalized; [O-1-(4-phenyl)-1H-pyrrole ferrocenyldithiophosphonate (TPFc)] monomer and its conductive copolymers with pyrrole and 4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)butane-1-amine were synthesized, characterized and their electrochromic properties were investigated. The spectroelectrochem. analyses demonstrated that the copolymer films reveal a reversible cycling with distinctive color changes in their reduced/oxidized forms. For the copolymer films P(TPFc-co-Py)/DCM, P(TPFc-co-Py)/CH3CN and P(TPFc-co-TPA)/DCM, the maximum optical contrasts (ΔT %) were measured as 28, 12 and 27% at 800, 900 and 900 nm, resp. Spectroelectrochem. anal. also revealed that all copolymers prepared with TPFc have lower band gaps compared to those of corresponding polymers.

Ikawa, Kurumi published the artcileNew in vitro SPF evaluation method for hydrophilic sunscreen samples, COA of Formula: C11H24O3, the publication is Journal of Oleo Science (2022), 71(2), 321-331, database is CAplus and MEDLINE.

A new method was developed for the in vitro sun protection factor (SPF) evaluation of sunscreen samples. A new type of substrate, a hydroxyalkyl cellulose-coated plate, was also prepared specifically for hydrophilic samples. This new substrate was required because hydrophilic samples would be unlikely to wet the surface of the standard cosmetic PMMA UV evaluation plate. A super-hydrophilic quartz plate was prepared by corona-discharge treatment before an aqueous solution of hydroxyalkyl cellulose was spread on it. A flat and uniform hydroxyalkyl cellulose film was subsequently formed through the evaporation of water. Special care was taken to inhibit the generation of spatial non-uniformity. Six hydrophilic sunscreen samples with in vivo SPF values of 56, 55, 52, 25, 15, and 4, were then applied to the prepared hydroxyalkyl cellulose-coated plate, as well as a super-hydrophilic quartz plate and a flat hydrophobic PMMA plate. The thicknesses of the applied layers were determined using a wheel-shaped wet film thickness gauge immediately after the application, and UV transmission was measured using an SPF analyzer. The value of in vitro SPF was calculated from the UV absorbance and the thickness of the layer. For two out of the six samples, PMMA plate could not be available, as the samples were unable to wet the PMMA surface. Relatively small differences were observed between the in vitro SPF values when the super-hydrophilic and hydroxyalkyl cellulose-coated plates were used. Samples exhibiting higher in vivo SPF were also associated with higher in vitro SPF values, although a linear relationship was not observed In contrast to the super-hydrophilic plate whose half-life of the super-hydrophilicity is only approx. five days, the hydrophilicity of the hydroxyalkyl cellulose-coated plate scarcely varied during six months of storage. Finally, a simplified evaluation method was also proposed. The validity of the method was verified through a ring test where three researchers employed this method in different laboratories at three independent organizations.

Gyulai, Orsolya published the artcileOn-line observation of the crystal growth in the case of the non-typical spherical crystallization methods of ambroxol hydrochloride, Safety of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride, the publication is Powder Technology (2018), 144-149, database is CAplus.

Spherical crystallization can be an important technol. step in the production of a solid form active agent. By the production of spherical crystals, direct compression tablet making can be applied to the powder material. This method makes the tableting process quicker, shorter and more economical with reduced amounts of additives and a reduced number of technol. steps. This way, the granulation method can be avoided, which is also advantageous for a moisture sensitive drug. In this paper, we presented Focused Beam Reflectance Measurement (FBRM) studies applied in the case of the non-typical spherical crystallization methods of the active pharmaceutical ingredient ambroxol hydrochloride. Spherical agglomeration and controlled cooling crystallization methods were carried out based on our previous studies regarding these methods and the crystal formation processes were investigated with FBRM probe. Critical agglomeration periods and other mechanisms, such as the breakage of the agglomerates and the precipitation of small particles, were investigated. Chord length values were observed continuously and samples were taken out in certain points of the crystallization Particle size anal. was carried out in each case to obtain information on the particle size enlargement caused by the crystallization methods. With the application of light microscopic anal., aspect ratio and roundness values were also determined to obtain pieces of information on the sphericity-changes of the particles throughout the crystallization and large improvements were presented either for these parameters (aspect ratio from ∼ 1.7 to ∼ 1.3; roundness from ∼ 2.4 to ∼ 1.5) and the mean particle size (from ∼13μm to 120-400μm). Among others, it was revealed that after the spherical agglomeration method (SA), mostly crystal agglomerates were formed, while slow cooling crystallization with alternating temperature profile (ATP) yielded larger and probably harder individual crystals.

Alsabte, Ahmed published the artcileEffects of Volatile Organic Compounds (VOCs) emitted by citrus infested with Aonidiella aurantii on the predator Rhyzobius lophanthae attraction, Safety of cis-3,7-Dimethyl-2,6-Octadien-1-Ol, the publication is Phytoparasitica (2022), 50(3), 645-653, database is CAplus.

This study identifies the volatile organic compounds (VOCs) emitted by citrus when infested with California red scale (Aonidiella aurantii) and determines which of these elicit behavior responses in the predator Rhyzobius lophanthae. Headspace solid-phase micro extractions (HS-SPME) technique combined with gas chromatog.-mass spectrometry (GC-MS) was used to identify compounds and Y-tube olfactometer to determine R. lophanthae behavior responses. According to the results, 22 VOCs were detected in infested citrus plants and some of them were increased in lemon, orange and tangerine by A. aurantii infestation. R. lophanthae individuals were attracted to infested citrus saplings. According to bioassays with the olfactometer, they were attracted to Me salicylate and D-limonene at dosages of 1 and 10μL/mL by using a Y-tube olfactometer. These results explain how citrus volatiles can affect the response of the predator R. lophanthae.

Naous, M. published the artcileSynergism in mixtures of n-octyl-β-D-thioglucoside and different n-alkyltrimethylammonium bromides: effect of the alkyl chain length, Synthetic Route of 85618-21-9, the publication is Colloid and Polymer Science (2012), 290(11), 1041-1051, database is CAplus.

Mixtures of n-octyl-β-D-thioglucoside with three different n-alkyltrimethylammonium bromides (n = 12 (DTAB), 14 (TTAB), and 16 (CTAB)) have been studied by using fluorescence spectroscopic techniques. The critical micelle concentration values of pure and mixed systems were determined by the pyrene 1:3 ratio method. The exptl. results were treated by using thermodn. mixing approaches based on the pseudo-phase separation model. All the mixed systems show a neg. deviation from ideal behavior, more pronounced with a larger alkyl tail of the co-surfactant. The three mixed systems fulfill the conditions of synergism, this behavior being also dependent on the alkyl chain length. By using the static quenching method, the mean micellar aggregation numbers of mixed micelles were obtained. In all the cases, the aggregation number is initially reduced with the participation of the cationic surfactant, remaining almost constant and close to the aggregation number of the pure cationic micelles. The local viscosity of pure and mixed micelles was examined by the photophys. response of the hydrophobic probe coumarin 6 solubilized in the micellar medium. The participation of the ionic component induces the formation of a less ordered structure than that of pure nonionic micelles. This effect becomes less pronounced as the chain hydrocarbon length of the co-surfactant increases.

Molina-Bolivar, J. A. published the artcileSurface Activity, Micelle Formation, and Growth of n-Octyl-β-D-Thioglucopyranoside in Aqueous Solutions at Different Temperatures, SDS of cas: 85618-21-9, the publication is Journal of Physical Chemistry B (2004), 108(34), 12813-12820, database is CAplus.

Micellization, surface activity, and structures of the aggregates of the nonionic surfactant n-octyl-β-D-thioglucopyranoside in aqueous solutions through a temperature range have been investigated. By using surface tension measurements, information was obtained on both changes in the critical micelle concentration and adsorption behavior in the air-liquid interface with the temperature These data were used to obtain the thermodn. properties of micellization along with the corresponding adsorption parameters in the air-liquid interface. The results obtained indicated that the surfactant headgroup has a more pronounced hydrophilic character than that of the common polyoxyethylenic nonionic surfactants. Size and structure of the micelles formed at different temperatures were investigated by light scattering measurements. The light scattering data, including static and dynamic experiments, account for micelle growth and hydration. The anal. of the exptl. results was focused on the phase transition from sphere to rodlike structures. To corroborate this point, addnl. measurements of d. and intramol. excimer formation of 1,2-dypyrenylpropane vs. the surfactant concentration were performed. Satisfactory agreement of the results, showing a significant micellar growth starting from a certain surfactant concentration, was observed by means of the different techniques used.

Hierrezuelo, J. M. published the artcileMicellar properties of a mixed surfactant system constituted by n-octyl-β-D-thioglucopyranoside and sodium dodecyl sulphate, Related Products of alcohols-buliding-blocks, the publication is Colloids and Surfaces, A: Physicochemical and Engineering Aspects (2005), 264(1-3), 29-36, database is CAplus.

A fluorescence probe study on micellization of the binary surfactant system formed by n-octyl-β-D-thioglucopyranoside (OTG) and Na dodecyl sulfate (SDS) in 0.1M NaCl aqueous solutions was carried out. The CMC exptl. data, as obtained by the pyrene 1:3 ratio method, were analyzed in the context of the pseudophase separation model. The interaction parameter (β₁₂) determined by using the regular solution theory (RST) is neg. and independent on the solution composition The exptl. data on micellar composition showed a good agreement with those predicted by RST. Data reported by a treatment based on the Gibbs-Duhem equation showed a reasonable agreement with those obtained by RST, suggesting that the mixed system behaves as a regular solution From the mixing thermodn. function values can be inferred that the electrostatic repulsions between the sulfate groups of SDS control the stability of the mixed micelles. Size of micelles was examined through the micellar aggregation number as obtained by the static quenching method. The aggregation number initially increases, giving a maximum value at low content of the ionic component, remaining almost constant at larger content of this one. This behavior was interpreted from the role played by the electrostatic repulsions between the headgroups of SDS in the stabilization of the mixed micelles. Finally, studies based on both pyrene 1:3 ratio index and intramol. excimer forming of 1,3-dipyrenylpropane solubilized in the micellar phase, reported information on the microenvironmental properties of mixed micelles. The results obtained were rationalized from 2 effects: the electrostatic repulsions between the headgroups of the ionic component and the micellar hydration.
