Bromide counterion as a spectroscopic sensor at the interface of cetyltrimethylammonium micelles

The strong UV absorption of the bromide in aqueous solution undergoes a remarkable red shift of more than 10 nm induced by the addition of the salts that constitute a saline buffer. The maximum absorption wavelength of the bromide is displaced from approximately 194 nm in ultrapure water to wavelengths above 200 nm, depending on the composition of the solution. The bromide spectrum as counterion of the cetyltrimethylammonium in the surfactant CTAB also shows sensitivity to the aggregation behavior of the tensioactive, being able to detect intermolecular interactions even at concentrations lower than the critical micelle concentration. And, when the micelles are assembled, the bromide absorption detects the interfacial rearrangements caused by the incorporation of ions. To know more about those interfadal features, the pyrene molecular probe was used, taking advantage of the extensive knowledge of its spectroscopy. Pyrene verifies the existence of changes in the interfadal organization which confirm that the sensitivity of the bromide spectrum is based on the ability of the ion to detect its microenvironment, and therefore reaffirms that its absorption spectrum can be used as a local sensor. The present work encourages the use of bromide as a sensor ion in the UV region between 190 and 210 nm. which would avoid the introduction of external molecular probes that could disturb the system.

N-Arylation of Nitrogen-Containing Heterocycles with Cu(II) Complex of 4-(2,2 ‘:6 ‘,2 ”-Terpyridin-4 ‘-yl)toluene as a Versatile and Efficient Catalyst

Copper(II) complex of 4-(2,2′:6′,2 ”-terpyridin-4’-yl)toluene(ttpy) was found to be a profitable catalyst for the N-arylation of a variety of nitrogen-containing heterocycles, such as some kinds of azoles and a secondary aliphatic amine, with aryl halides (iodides, bromides, and chlorides) under moderate conditions. A variety of functionalized aryl halides were tolerated in good to excellent yields by this air stable and low cost Cu(II)-based catalytic system. Phenyl boronic acid was also used as an alternative to aryl halides to supply aryl moiety.

Molecular design and experimental study on synergistic catalysts for the synthesis of cyclocarbonate from styrene oxide and CO2

Taking the reaction between styrene oxide and CO2 to yield cyclocarbonate as the target, the activities of synergistic catalysts, which are composed of Br- and alcohol compounds serving as hydrogen bond donors (HBDs), were predicted by DFT calculations and confirmed by subsequent experiments. Intramolecular reactions of the active intermediate as well as intermolecular reactions between the active intermediate and styrene oxide were possible side reactions. DFT calculation results show that the most likely by-product is phenylacetone, which is produced from the intramolecular reaction of the active intermediate. According to the calculation results, the catalytic activity of a synergistic catalyst is related to the pK(a) of the HBD, and the optimal calculated pK(a) is about 3-4 fold higher than the pK(a) of 2-bromo-1-phenylethanol, which is the protonated active intermediate of the target reaction. The combination of water and tetraethylammonium bromide (TEAB) was found to be a promising synergistic catalyst, and it can give a conversion of 50% and a yield of 43% under the conditions of 1% (mol%) catalyst loading, solvent free, 100 degrees C, 1.0 MPa and 1 h. Additionally, the TEAB can be reused. The observed catalytic activity of water is higher than expected but similar to that of styrene glycol, which is the hydration product of styrene oxide. Water is therefore an indirect catalyst and the catalytic activity is mainly contributed by the styrene glycol.

Irreversibility in Anion Exchange Between Cesium Lead Bromide and Iodide Nanocrystals Imaged by Single-Particle Fluorescence

Anion exchange is a powerful method to tune the emission wavelength of perovskite CsPbX3 (X = CI, Br, or I) nanocrystals across the visible spectrum. CsPbX3 nanocrystals can possess a number of crystal structures that depend on both their composition and size. Understanding the role these structural variations play during anion exchange is important for their future application in optoelectronic devices. In this work, we used fluorescence microscopy to monitor reaction trajectories of individual nanocrystals as they undergo anion exchange between CsPbBr3 and CsPbI3. By varying the concentration of substitutional ion used to induce anion exchange, we quantify differences in reaction times for exchange in opposite directions. CsPbI3 nanocrystals undergo more abrupt shifts in their emission characteristics as they transform to CsPbBr3, while CsPbBr3 nanocrystals exhibit a smoother transition during their transformation to CsPbI3. Simulations of anion exchange using Monte Carlo trajectories are consistent with a larger degree of structural reorganization when CsPbI3 nanocrystals undergo anion exchange. Together, these results reveal that there are structural differences between CsPbI3 nanocrystals synthesized by the hot-injection method and those produced by anion exchange. The narrower distribution of reaction times when CsPbI3 nanocrystals transform to CsPbBr3 may produce better compositional homogeneity when this reaction is scaled-up to incorporate these materials into optoelectronic devices.

A transparent-to-gray electrochromic device based on an asymmetric viologen

A transparent-to-gray electrochromic device (ECD) based on an asymmetric viologen was fabricated and characterized. The core material derived from novel bipyridine salt (named 1-(2-(diethoxy-phosphoryl)ethyl)-1 ‘-(4-vinylbenzyl)-[4,4 ‘-bipyridine]-1,1 ‘-diium chloride bromide, DVB) combined with complementary species of ferrocene was assembled in a device with a simple configuration of ITO/EC solution/ITO. The device was first converted to blue color from transparent when 1.0 V was applied, and then neutral gray color when the potential bias was increased to 2.0 V. Meanwhile, the corresponding optical contrasts (Delta T) were 54.5% and 22% at 392 nm and 605 nm, respectively. In addition, a good coloration efficiency of 128.9 cm(2) C-1 at 2.0 V and fast switching time (<2.5 s) were obtained. Finally, satisfied stability with 43.8% of Delta T (maintaining 80% of initial Delta T at 392 nm) was achieved after 2000 cyclic processes, which paves a new way to design colorless to neutral color ECDs.

Solvothermal synthesis and modification of NaYF4:Yb/Er@NaLuF4:Yb for enhanced up-conversion luminescence for bioimaging

Water-soluble NaYF4:Yb/Er@NaLuF4:Yb up-converting nanoparticles (UCNPs) with a strong green emission were successfully prepared by a solvothermal method in a short period of time and at a low temperature. First, the hydrophobic UCNPs were prepared by a simple solvothermal method, then modified using a polyetherimide (PEI) surfactant or oxidation of the oleic acid ligands with the Lemieux-von Rudloff reagent. The modified UCNPs, having an average particle diameter of 60 +/- 5 nm, showed a high dispersity. The oleic acid ligand on the sample surface was oxidized azelaic acid (HOOC(CH2)(7)COOH), identified from Fourier transform infrared (FTIR) spectroscopy, which results in the generation of free carboxylic acid, hence conferring a high solubility in water. The 3-4,5-dimethylthiazol-2-yl-2,5-diphenyl tetrazolium bromide (MTT) method and cell-targeted labeling proved that oleic acid-capped UCNPs after oxidation (UCNPs-OAO) have a higher biocompatibility than polyetherimide-capped UCNPs (UCNPs-PEI). Therefore, the UCNPs-OAO have a great potential in biomedical applications, such as multimodal imaging, targeted therapy, and gene therapy.

Improving the Identification and Coverage of Plant Transmembrane Proteins in Medicago Using Bottom-Up Proteomics

Plant transmembrane proteins (TMPs) are essential for normal cellular homeostasis, nutrient exchange, and responses to environmental cues. Commonly used bottom-up proteomic approaches fail to identify a broad coverage of peptide fragments derived from TMPs. Here, we used mass spectrometry (MS) to compare the effectiveness of two solubilization and protein cleavage methods to identify shoot-derived TMPs from the legume Medicago. We compared a urea solubilization, trypsin Lys-C (UR-TLC) cleavage method to a formic acid solubilization, cyanogen bromide and trypsin Lys-C (FA-CTLC) cleavage method. We assessed the effectiveness of these methods by (i) comparing total protein identifications, (ii) determining how many TMPs were identified, and (iii) defining how many peptides incorporate all, or part, of transmembrane domains (TMD) sequences. The results show that the FA-CTLC method identified nine-fold more TMDs, and enriched more hydrophobic TMPs than the UR-TLC method. FA-CTLC identified more TMPs, particularly transporters, whereas UR-TLC preferentially identified TMPs with one TMD, particularly signaling proteins. The results suggest that combining plant membrane purification techniques with both the FA-CTLC and UR-TLC methods will achieve a more complete identification and coverage of TMPs.

MiR-16 inhibits hepatocellular carcinoma progression by targeting FEAT through NF-kappa B signaling pathway

OBJECTIVE: MicroRNA-16 (miR-16) expression has been proved to take part in the initiation and development of several cancers, including hepatocellular carcinoma (HCC). However, its role and its molecular mechanism in HCC cells remain unclear. Our study aimed to elucidate miR-16 probable role and potential mechanism in HCC cells. PATIENTS AND METHODS: MiR-16 expression in HCC was measured by Real Time-Polymerase Chain Reaction (RT-PCR). MiR-16 mimic or inhibitor was applied to increase or decrease miR-16 expression in Huh7 cells separately. The cell viability was measured by MTT (3-(4,5-dimethylthiazol-2-yl)-2.5-diphenyl tetrazolium bromide). The invaded cells and migrated cells were detected by the transwell assay. The epithelial-mesenchymal transition (EMT) and the nuclear factor-kappa B (NF-kappa B) were performed using Western blot. The tumor growth was measured via xenograft tumor formation assay. Moreover, bioinformatical methods and luciferase reporter assay were carried out to confirm the miR-16 target gene. RESULTS: MiR-16 expression was downregulated in HCC tissues and cells. Furthermore, the increasing miR-16 expression was suppressed. whereas the decreasing miR-16 expression promoted cell proliferation, invasion, and migration in Huh7 cells. Moreover, miR-16 targeted FEAT in regulating HCC progression. FEAT was associated with a poor prognosis of HCC patients. Especially. miR-16 suppressed EMT and NF-kappa B pathway in HCC and inhibited the tumor growth in vivo. CONCLUSIONS: We stated that miR-16 suppressed HCC cell progression by targeting FEAT and inhibiting EMT and NF-kappa B pathway. MiR-16 may be clinically utilized as a factor for the clinical diagnosis and prognosis of HCC.
