Eight half-sandwich iridiumIII (IrIII) complexes of the general formula [(η5-Cpxbiph)Ir(O^N)Cl] (Cpxbiph is tetramethyl(biphenyl)cyclopentadienyl, and the O^N is α-picolinic acid chelating ligand and its derivatives) were synthesized and characterized. Compared with cis-platin widely used in c...

The effect of adding styrene-butyl acrylate (SBA) nano copolymer latex on the mechanical properties of concrete is investigated via performing scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDX) analyses. For decreasing entrapped air content and increasing workabili...

Styrene-butyl acrylate (St-BuA) copolymers were obtained by mass free radical copolymerization reactions, using BPO as initiator. A 70:30 (St-BuA) comonomer composition was selected. Three different molar concentrations of sulfonating agent (50, 100 and 150%) were considered to obtain the sulfon...

The paper presents the studies on the optimization of the free-radical graft reaction applying the “grafting from” method of terpene acrylate monomers prepared from two geometric isomers of terpene alcohol such as trans-3,7-dimethyl-2,6-octadien-1-ol (geraniol) and cis-3,7-dimethyl-2,6-octadie...

Nowadays, conductive and semi-conductive fabrics has been attracted by different industries such as medical textile, electronic, sensors, electrodes and flexible resistance due to flexibility, lightness and wide range of applications. Here, poly (3, 4-ethylenedioxythiophene):poly(styrenesulfonat...

The creation of micrometer adhesive pads by dewetting and subsequent crosslinking of a benzophenone-acrylate copolymer onto a substrate that is lithographically patterned with a benzophenone-fluoropolymer, has been investigated in relation to the adhesive performance of either continuous or patt...

In the present work, the temperature dependence of the molar heat capacity of chitosan-graft-poly(2-ethylhexyl acrylate) copolymer was measured for the first time in the temperature range from 6 to 350 K by precise adiabatic calorimetry, and the thermophysical properties of copolymer were studie...

This paper focuses on the chemical modification of potato starch by the cinnamyl acrylate monomer during the graft copolymerization. The maximum of the grafting percent (G) was found to be 49.2% ± 0.3 at the temperature of 65 °C for 120 min in the presence of 1.0 wt% of potassium persulfate at...

A novel polyurea-crosslinked cationic acrylate copolymer (PUAM) with antibacterial activity, using 3-(methacryloylamino) propyl trimethyl- ammonium chloride (MPAC) as antibacterial functional monomer, had been successfully synthesized by via soap-free emulsion polymerization. The microscopic mor...

The effect of the structure of aromatic acrylate-fluoroacrylate copolymers on CO2 viscosity at elevated pressures was investigated. These copolymers were all found to be miscible with CO2 at pressures between 10–15 MPa (295 K) and induce an increase in the viscosity to some degree. It appears t...

The role of heart-type fatty acid-binding protein (FABP3) in human physiology as an intracellular carrier of fatty acids (FAs) has been well-documented. In this study, we aimed to develop an analytical method to study real-time interaction kinetics between FABP3 immobilized on the sensor surface...
