Thermochromic films with intriguing functionalities have great potential in soft actuators, heat storage devices, and interactive interface sensors. Inspired by the unique features of bird feathers (such as Nicobar pigeon, Anna hummingbird, mandarin duck, etc.), a superhydrophobic thermochromic film (STF) with robust healability is proposed for the first time through sandwiching an electric heater between a top thermochromic layer and a bottom poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) substrate. The STF exhibits fast and reversible color conversions of blue-pink-yellow under a low input power and has a superhydrophobic property with a contact angle of 155. Furthermore, owing to the strong dynamic dipole-dipole interactions between the polar CF3 groups of flexible PVDF-HFP chains, the STF possesses a robust healing capability of structure and conductivity. By means of the temperature difference generated by the objects contacting (finger, iron, and water) as a stimulus, the STFs achieve tactile imaging and writing record with advantages of transient display, automatic erasure, and excellent reusability. Additionally, the STF-based anti-counterfeiting security labels with superhydrophobicity and three-state color switching simultaneously realize facile distinguishment and difficult forgery. The findings conceivably stand out as a new methodology to fabricate functional thermochromic materials for innovative applications.

The solubilization effect of 14-s-14 series dicationic surfactants is quantified via spectrophotometry using a thymolphthalein hydrophobic indicator. It is shown that the solubilization capacity of the studied micellar solutions with respect to the neutral form of thymolphthalein increases along with the length of the spacer moiety and grows by as much as five times upon transitioning from 14-2-14 to 14-6-14. It is concluded that the solubilization of thymolphthalein is accompanied by a shift in the acid-base equilibria in which this compound participates, as is reflected in the drop of its pK a value and the shift of the region of color change.

An activity is described in which items found around the home are used in electrochemical experiments to create messages and artistic designs. To do so, a battery is connected to wires fashioned out of aluminum foil. When these wire electrodes are touched to a paper towel soaked in fluids obtained from household cleaners or disinfectants, the resultant redox reactions cause color changes on the paper towel. For example, the reduction of water at a cathode can cause a blue color to develop on a paper towel soaked in foam cleaner that contains thymolphthalein, and oxidation of iodide ions at an anode can produce a black color on a paper towel soaked in decolorized iodine. The experiments are very simple to set up and carry out; produce striking visual results; and relate to concepts in electrochemistry, acid-base chemistry, and thermodynamics. As such, the activity may be tailored for use in settings that range from outreach events to general- and analytical-chemistry courses.

Chemistry is traditionally divided into organic and inorganic chemistry. Formula: C26H29N3O2, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 1552-42-7

In this article, a crucial compound, crystal violet lactone (CVL), was prepared by the reaction of N,N-dimethylaniline, p-dimethylanimobenzaldehyde and m-dimethylanimobenzoic acid. Taking alcohols or carboxylic acids as solvents, 15 novel reversible thermochromic complexes were prepared by means of chelation reaction between electron donor CVL and electron acceptor such as various phenols, aromatic amines, carboxylic acids, and Lewis acids, respectively. The structure of CVL is characterized by 1H NMR and MS. The reversible thermochromic behavior of these compounds are studied by DSC/TG, IR, and Raman spectrum. Results indicate that mechanism of these reversible thermochromic complexes is the lactone ring tautomerism when the temperature is low or high. Thermochromic color degree of these complexes is dependent on the acidity of electron acceptor and thermochromic temperature is dependent on the properties of solvent compounds. The properties of electron acceptor and solvent compounds also determined the thermochromic process of the complexes, which followed the first-order kinetic equation, and the values of energy of activity (E a) of thermochromic process are correlated with the components of the complexes nearly. The stronger the acidity of phenols is, and the deeper the thermochromic color degree is, the higher the value of Ea is, when electron acceptors are phenols.

Pancreatic lipase inhibitory effect of some edible spices in light of percent inhibition, efficacy, reversibility/irreversibility and effect of pH on inhibition is presented here. Lipase inhibitory activities of methanolic extracts of eighteen spices were evaluated. Extracts of Zanthoxylum armatum, Cinnamomum tamala, Syzygium aromaticum and Myristica fragrans were considered to be of high potency in synthetic substrate assay. Only Syzygium aromaticum showed high potency in natural substrate based lipase assay. Zanthoxylum armatum extract displayed lowest IC50 of 9.0 mug/mL. On dialysis, all extracts lost their lipase inhibitory activity indicating reversible nature of inhibition. pH significantly affected the performance of spice extracts during inhibition of pancreatic lipase. Most of the extracts lost their pancreatic lipase inhibitory activity at pH 3.0 with the exception of Brassica nigra and Cinnamomum tamala. Results showed spice are good source of pancreatic lipase inhibitor and its potential as drug for obesity can be explored by addressing various issues.

Antiatherosclerotic effects of small-molecular-weight compounds enhancing endothelial nitric-oxide synthase (eNOS) expression and preventing eNOS uncoupling

Many cardiovascular diseases are associated with reduced levels of bioactive nitric oxide ( NO) and an uncoupling of oxygen reduction from NO synthesis in endothelial NO synthase ( eNOS uncoupling). In human endothelial EA.hy 926 cells, two small-molecular-weight compounds with related structures, 4-fluoro-N-indan-2-yl-benzamide ( CAS no. 291756-32-6; empirical formula C16H14FNO; AVE9488) and 2,2-difluoro-benzo[1,3] dioxole-5-carboxylic acid indan-2-ylamide( CAS no. 450348-85-3; empirical formula C17H13F2NO3; AVE3085), enhanced eNOS promoter activity in a concentration-dependent manner; with the responsible cis-element localized within the proximal 263 base pairs of the promoter region. RNA interference-mediated knockdown of the transcription factor Sp1 significantly reduced the basal activity of eNOS promoter, but it did not prevent the transcription activation by the compounds. Enhanced transcription of eNOS by AVE9488 in primary human umbilical vein endothelial cells was associated with increased levels of eNOS mRNA and protein expression, as well as increased bradykinin-stimulated NO production. In both wild-type C57BL/6J mice and apolipoprotein E-knockout ( apoE-KO) mice, treatment with AVE9488 resulted in enhanced vascular eNOS expression. In apoE-KO mice, but not in eNOS-knockout mice, treatment with AVE9488 reduced cuff-induced neointima formation. A 12-week treatment with AVE9488 or AVE3085 reduced atherosclerotic plaque formation in apoE-KO mice, but not in apoE/eNOS-double knockout mice. Aortas from apoE-KO mice showed a significant generation of reactive oxygen species. This was partly prevented by nitric-oxide inhibitor N-omega- nitro-L-arginine methyl ester, indicating eNOS uncoupling. Treatment of mice with AVE9488 enhanced vascular content of the essential eNOS cofactor ( 6R)-5,6,7,8- tetrahydro-L-biopterin and reversed eNOS uncoupling. The combination of an up-regulated eNOS expression and a reversal of eNOS uncoupling is probably responsible for the observed vasoprotective properties of this new type of compounds.
