A new metal-affinity sorbent based on lanthanum stearate monolayers has been developed and characterized. The prospect of its application to specific extraction of organophosphorous compound (OP) adducts of blood proteins was demonstrated. For this, the patterns of soman adducts of human serum a...

One of the main goals of computing with words is the accurate modeling of natural language. In this direction, Z-numbers were introduced by Zadeh in 2011 as a pair of fuzzy numbers, (A, B), where A is interpreted as a fuzzy restriction on the values of a variable, while B is interpreted as a mea...

An embedded graph is called z-knotted if it contains a unique zigzag (up to reversing). We consider z-knotted triangulations, i.e. z-knotted embedded graphs whose faces are triangles, and describe all cases when the connected sum of two z-knotted triangulations is z-knotted.

Zn-substituted Z-type Sr hexaferrites (Sr3Co2-xZnxFe24O41, x = 0, 0.5, 1.0, 1.5) were prepared by solid-state reaction routes. The magnetic and high-frequency properties of the sintered bodies and powder–epoxy composites were studied. Almost-single-phase Z-type hexaferrite could be obtained in ...

Let Γ be a triangulation of a connected closed 2-dimensional (not necessarily orientable) surface. Using zigzags (closed left–right walks), for every face of Γ we define the z-monodromy which acts on the oriented edges of this face. There are precisely 7 types of z-monodromies. We consider th...

Bacterial cell division is mediated by the divisome which is organized by the Z ring, a cytoskeletal element formed by the polymerization of the tubulin homologue FtsZ. Despite billions of years of bacterial evolution, the Z ring is nearly universal among bacteria that have a cell wall and divid...

Albumin-scavenging surfaces decorated with n-alkyl chains represent an established strategy for blood-contacting applications. To evaluate this concept, a set of poly (2-hydroxyethyl methacrylate) (pHEMA) films modified with different amounts of octadecyl isocyanate (C18) was investigated in an ...

The solid-state photopolymerization of octadecyl vinyl ether was verified occur in rotator phase, and the stability of octadecyl vinyl ether in rotator phases was explained through the study of its electrostatic surface potential. Four binary systems were constructed by mixing the octadecyl viny...

Emulsion polymerizations of dodecyl and octadecyl methacrylate were carried out using a conventional water soluble initiator and sulphonate surfactant in the presence of β cyclodextrin. For the first time stable latices that were taken to high conversion of monomer were produced. It is thought ...

Stationary phase selectivities for halogenated compounds in reversed-phase HPLC were compared using C18 monolithic silica capillary columns modified with poly(octadecyl methacrylate) (ODM) and octadecyl moieties (ODS). The preferential retention of halogenated benzenes on ODM was observed in met...

Nanocomposites with polystyrene, poly(styrene-co-methyl methacrylate) and poly(styrene-co-octadecyl methacrylate) matrix and pristine or oxidized, methyl ester, dodecyl ester, ethyl benzene ester functionalized multiwall carbon nanotubes are prepared by in situ polymerization reaction. Performed...

The side chain crystallization of poly(n-octadecyl methacrylate) (PODMA) homopolymers with different molecular weight as well as small lamellar and cylindrical PODMA domains in microphase-separated poly(styrene-b-octadecyl methacrylate) block copolymers is studied by calorimetry and scattering t...

Polyethylene glycol octadecyl ether methacrylate (C18E2MMA) was synthesized using polyethylene glycol octadecyl ether (C18E2) and methyl methacrylate (MMA) as raw materials. Then it was free radical polymerized to form a comb-like polymeric phase change material (PPCM)-poly(polyethylene glycol o...

Miscibility and rheological properties like kinematic viscosity at 40 °C and 100 °C, viscosity index, shear stability and pour point for solutions of polyolefin copolymer (OCP) and terpolymer poly(styrene-co-dodecyl methacrylate-co-octadecyl methacrylate) (PSAMA) in lubricating mineral oil are...

The novel liquid membrane system, which is named polymeric pseudo-liquid membrane, was constructed from poly(octadecyl methacrylate) (PC18MA), which showed a rubbery state under operating conditions, as a membrane matrix, and dibenzo-18-crown-6 (DB18C6) for the transport of KCl or O-allyl-N-(9-a...

During the development of a palladium catalyzed C–H activation cross-coupling reaction involving acyl halides, it was noted that palladium(II) acetate catalyzes the acylative cleavage of tetrahydrofuran (used as a solvent) at room temperature to afford the corresponding 4-chlorobutyl ester deri...

Tris(2-butoxyethyl) phosphate (TBOEP) is an organophosphate ester used as substitute following the phase-out of brominated flamed retardants. Because of its high production volume and its use in a broad range of applications, this chemical is now frequently detected in the environment and biota....

Following the ban of polybrominated diphenyl ether (PBDEs) flame retardants under well-documented toxicity issues, organophosphate such as tris(2-butoxyethyl) phosphate (TBOEP) and tris(2-cloroethyl) phosphate (TCEP) were considered as potential substitutes. Although TBOEP and TCEP are consisten...

Tris(2-butoxyethyl) phosphate (TBOEP) is a plasticizer present in indoor dust, reaching levels of several micrograms per gram. Such levels could lead to significant daily exposure of adults and children. Currently, no toxicokinetic data are available to estimate TBOEP clearance in humans after u...

The isothermal synthetic method was used to measure CO2 solubilities in three high-boiling-point absorbents, such as 2-ethoxyethyl ether, 2-butoxyethyl acetate and 2-(2-ethoxyethoxy)ethyl acetate under pressures ranging from 0 to 1.3 MPa and temperatures ranging from 293.15 to 333.15 K. Henry&#x...
