Two derivative ligands of diethylenetriamine-N,N,N′,N′′,N′′-pentaacetic acid (H5DTPA; H5L1) were synthesized: the symmetric and asymmetric mono(methylamides) DTPA-N′-MA (H4L3) and DTPA-N-MA (H4L4). The protonation constants (log KiH) of L3 and L4 were obtained by pH-potentiometric titration: 10.04, 8.41, 2.73, 1.94 an…

Photoelectrochemical experiments have been carried out for characterizing passive films on Mo‐Ta sputtered alloys having different compositions, as well as on pure Mo and Ta metals. Both corrosion layers, formed by simple immersion in solution, and films grown anodically were investigated. The presence of Mo species i…

In this paper we examine nonradiative processes (cross relaxation and energy migration) vital for the generation of blue avalanche emission in ${\mathrm{T}\mathrm{m}:\mathrm{L}\mathrm{i}\mathrm{Y}\mathrm{F}}_{4}$ crystals subjected to radiation near 648 nm. Time-domain and temperature-dependent measurements indicate t…

A UNESCO designated World Heritage Site, the city of Bath has many important listed buildings largely constructed of limestone from local quarries. Among present day atmospheric pollutants, SO2 is particularly damaging to calcareous stone, although its levels are decreasing with the use of low sulphur oil and coal, fl…

With tetrahydrofuran as a solvent and pyridium p-toluenesulfonate as a catalyst, the hydroxyalkyl vinyl ethers 2-hydroxyethyl vinyl ether (2E), 4-hydroxybutyl vinyl ether (4B), and 6-hydroxyhexyl vinyl ether (6H) underwent step-growth self-polyaddition, generating polymers with an acetal main-chain structure. The mole…

Differential scanning calorimetry (DSC) is one of the most used methods for kinetic studies of thermoset cure reactions. The basic assumption made in this technique is the proportionality between the heat generation rate and cure reaction rate. To have access to the heat generation rate that provides information about…

The production of spherical crystals has recently gained great attention due to the fact that the crystal habit (form, surface, size, etc.) can be modified during the crystallization process. Spherical crystals of ASA were developed by non-typical and typical spherical crystallization techniques. The non-typical spher…

Blends of two or more ethylene–styrene (ES) copolymers that differed primarily in the comonomer composition of the copolymers were studied. Available thermodynamic models for copolymer–copolymer blends were utilized to determine the criteria for miscibility between two ES copolymers differing in styrene content and al…

New biomedical polymers were designed with attention to the surface of biological membranes, i.e. the surface was completely covered with phospholipid polar groups. The polymers with a phosphorylcholine group, 2-methacryloyloxyethyl phosphorylcholine (MPC) co-polymerized with hydrophobic alkyl group, could interact wi…

Blue-laser irradiation of a single crystal of the chloride salt of a cationic complex, trans-[Ru(en)2(H2O)(NO)]3+ (en = ethylenediamine), yielded MS1 (a metastable state of end-on type) which is remarkably stable (decay temperature Td = 267 K) compared with MS1 of sodium nitroprusside Na2[Fe(CN)5(NO)] (SNP). No MS2 st…

A two-dimensional, coupled, cellular automaton-continuum model was developed to model the evolution of solidification grain structures and the deflection behavior of the columnar dendritic grains solidified in a flowing melt. Al-Cu alloys were solidified on an inclined Cu chill in order to investigate the deflection b…

Mitomycin-C (MMC)-loaded poly(DL-lactide) (PLA)/poly(DL-lactide-co-glycolide) (PLGA) films which have different drug loading capacities and thicknesses were prepared by a solvent-evaporation technique. Degradation and release studies were conducted at 37 degrees C in pH 7.4 phosphate buffered saline. The results showe…

Cyanoethylation of jute fiber in the form of nonwoven fabric was successfully achieved using an acrylonitrile monomer which is said to react with the hydroxyl groups of fiber constituents. The degrees of cyanoethylation to different extents were undertaken by varying the reaction time. An IR study showed that extent o…

To improve the interfacial adhesion between evaporated copper film and poly(ethylene terephthalate) (PET), the surface of PET films was modified by treating with hydrazine monohydrate. The effect of the treatment time in the range of 5-20 min with 80 wt% hydrazine monohydrate at 60 °C on the number of polar groups cre…
