2-Alkyl-7-methoxy-5-nitrobenzo[b]furan, 2-alkyl-9-methoxy-7-nitro-3-oxo-2,3-dihydro-5H-benzo[e][1,4]-dioxepin-5-yl acetate and 2-alkyl-5-hydroxy-9-methoxy-7-nitro-5H-benzo[e][1,4]-dioxepin-3-one were formed as a result of the cyclization of 2-(2-formyl-6-methoxy-4-nitrophenoxy)alkanoic acids und...

Ultrathin fluoropolymer films were prepared by depositing poly[2-(perfluorooctyl)ethyl acrylate] (PFOEA) on 12.5 cm diameter silicon wafer substrates using high-pressure free meniscus coating (hFMC) with liquid CO2 (l-CO2) as a coating solvent. Dry film thickness across the wafer substrate and t...

Deposition from two immiscible supercritical phases (DISP), in which a solution of supercritical carbon dioxide (scCO2) with a desired solute is displaced by supercritical helium (scHe), has been applied to deposit poly[2-(perfluorooctyl)ethyl acrylate] (PFOEA) on silicon wafer substrate coupons...

Topologically ordered surfaces with a polymer brush-grafted layer were prepared by a combination of nano-imprinting (NI) and surface-initiated atom transfer radical polymerization (SI-ATRP). The molecular aggregation state and the wetting were evaluated by synchrotron radiation X-ray analyses an...

Publisher SummaryThis chapter focuses on β-hydroxydecanoyl thioester dehydrase, the present preparations of which are homogeneous in the ultracentrifuge and migrate as a single entity on polyacrylamide gels. The thioester derivatives of the straight-chain 10-carbon acids are the most active sub...

β — Hydroxydecanoyl — [acyl — carrier — protein] dehydrase catalyzes the essential step in the formation of unsaturated fatty acids in Escherichia coli. This reaction was characterized with native C10 acyl—acyl-carrier protein (ACP) structures in both an aqueous phase system and a substrat...

BackgroundThe most fundamental problem in cancer biology research is to understand the mechanisms of cancer cell resistance to oncological therapies. Literature reports emphasize the important role of adhesion molecules: intercellular adhesion molecule 1 and vascular cell adhesion molecule 1 (IC...

The role of calcium-activated chloride channels for renal function is unknown. By immunohistochemistry we demonstrate dominant expression of the recently identified calcium-activated chloride channels, Anoctamin 1 (Ano1, TMEM16A) in human and mouse proximal tubular epithelial (PTE) cells, with s...

Polycystic kidney diseases are characterized by multiple bilateral renal cysts that gradually enlarge and lead to a decline in renal function. Cyst enlargement is driven by transepithelial chloride secretion, stimulated by enhanced levels of cyclic adenosine monophosphate, which activates apical...

Rate constants for the decay of the Eu3+(5D1) state in dilute Eu3+-doped tris(2,2,6,6-tetramethyl-3,5-heptanedionato)gadolinium(III) are reported for a temperature range 50–315 K. A temperature-independent contribution of 1.3×106 s−1 is attributed to carbonyl mediated 5D1→5D0 relaxation. A te...

In this work is reported the synthesis, characterization, luminescent properties and positronium formation yields of europium(III) and terbium(III) complexes of stoichiometric formula Ln(dpm)3(2-pyr), where: Ln = Eu and Tb, dpm = 2,2,6,6-tetramethyl-3,5-heptanedionato (dipivaloylmethanate) ion, ...

Zinc oxide (ZnO) nanowire (NW) arrays were grown on Si (100) substrate by metal-organic chemical vapor deposition (MOCVD) via Zn[TMHD]2 as precursor. Here we adopted two different procedures to grow ZnO NWs namely, colloid and sputtered Au pre-deposition on Si (100) substrate. Comparative studie...

The fabrication and photophysical characterization of polymeric fiber preforms, obtained from a polymerization process of poly(methyl methacrylate) (PMMA) doped with terbium(III)-tris-(2,2,6,6-tetramethyl-3,5-heptanedionate) (Tb(tmhd)3) at 1.12–1.13 mmol concentration and co-doped with europium...

The potential of aqueous ammonium based IL, tetrabutylammonium-hydroxide (TBAOH), the aqueous tertiary amine, piperazine (PZ) and two aqueous solutions of TBAOH and PZ blend for CO2 capturing was estimated by solubility study. For this purpose, the experiments were carried at five different pres...

The efficiency of various gold compounds containing bis(phosphino)ferrocene ligands for catalyzing ring-closing reactions was examined. Six commercially available bis(phosphino)ferrocene ligands: 1,1′-bis(ditert-butylphosphino)ferrocene (dtbpf), 1,1′-bis(diphenylphosphino)ferrocene (dppf), 1,1...

Despite the interactions of tetrabutylammonium fluoride and tetrabutylammonium acetate interacted with 1-(4-nitrophenyl)-3-((pyridin-4-yl)methyl)thiourea (L) show similar absorption at 479 nm, the color intensities are different. This helps to distinguish these two ions in independent solution b...

This work reports on the successful exploitation of a nanocomposite comprising HO-functionalized multi-walled carbon nanotubes decorated with electrochemically-grown rhodium nanoparticles (MWCNT-OH/Rh) as a cathode material in dye-sensitized solar cells (DSCs). Electrochemical investigations rep...

A novel struvite crystallization method induced by electrochemical acidolysis of cheap magnesite was investigated to recover phosphorus from aqueous solution. Magnesite was confirmed to continuously dissolve in the anolyte whose pH stabilized at about 2. Driven by the electrical field force, ove...

During the struvite (MgNH4PO4·6H2O) recovery from agricultural or industrial wastewater, the extensive existence of heavy metals would pose great threats to the planting and environment. This work revealed the association of kinds of heavy metals, as possible substances in the wastewater, with ...
