A facile aluminum based superhydrophobic thin films were electrodeposited by mixing aluminum isopropoxide (AlOx) with stearic acid (SA) onto the copper substrates via one-step method. The energy dispersive X-ray spectroscopy (EDS) attenuated total-reflectance Fourier Transmission infrared spectr...

Cerium and cerium containing materials have been drawing increasing attentions in industrial and biomedical applications in recent decades. The increased applications of cerium have also increased the risk of human body exposed to cerium ions. Due to its similar ionic radius to calcium(II), ceri...

We used Wiener's method (a laser sheet deflection technique abbreviated LLD) to determine how well LLD (laser line deflection) could detect different diffusive layers within a glassy polymer system of poly(methyl methacrylate) with its own monomer of methyl methacrylate. LLD showed distinct...

An organic monolithic column based on the co-polymerization of 2-naphthyl methacrylate (NAPM) as the functional monomer and trimethylolpropane trimethacrylate (TRIM) as the crosslinker was introduced for high performance reversed-phase liquid chromatography (RPC). The co-polymerization was perfo...

Poly(dimethylsiloxane)-containing macro-azo-initiator was used in dispersion polymerization of methyl methacrylate. Stable microspheres were obtained when the solvents had solubility parameters in the range of 7.4–8.2. The microspheres were stabilized by a stabilizer formed in-situ, that is, po...

Anionic polymerization high vacuum techniques were employed for the synthesis of a diblock (PS-b-PtBuMA) and two triblock (PS-b-PtBuMA-b-PS) copolymers of polystyrene (PS) and poly(t-butyl methacrylate) (PtBuMA) bearing similar low molecular weight PS end-block(s). Dilute solution viscometry, as...

Novel (meth)acrylate tetrapolymers based on 2-hydroxyethyl methacrylate (HEMA) were synthesized via free-radical polymerization in refluxing xylene under monomer-starved conditions for use in negative photoresist formulations. 2,2′-Azobis(2-methylbutyronitrile) was used as initiator and 2-merca...

Two new azo-perester compounds, di-tert-butyl-6,6′-azobis-(6-cyanoperoxyheptanoate) (6,6-di-tBu) and di-tert-amyl-6,6′-azobis-(6-cyanoperoxyheptanoate) (6,6-di-tAm), synthesized on the basis of 6,6′-azobis-(6-cyanoheptanoic acid) (ACHpA), were investigated for their use in the radical polymer...

Experimental densities, dynamic viscosities, speeds of sound and relative permittivities for ten binary mixtures of methyl acetate +, ethyl acetate +, butyl acetate +, isoamyl acetate +, methyl propionate +, ethyl propionate +, ethyl butyrate +, methyl methacrylate +, ethyl methacrylate +, and b...

A novel, high-refractive index, methacrylic monomer was produced by incorporating 1-diamantane-carboxylic acid (1-D2-CA) and glycidyl methacrylate (GMA). The resulting monomer was gently polymerized with organic peroxide, and was formed transparent polymer thin film. Physicochemical and optical ...

This paper describes the fabrication of long alkyl chain methacrylate monolithic materials for using as stationary phases in capillary liquid chromatography. Following deactivation of the capillary surface with 3-(trimethoxysilyl)propyl methacrylate (γ-MAPS), monoliths were formed by co-polymer...

Random copolymers of perfluoroalkyl ethyl methacrylate (Zonyl-TM), methyl methacrylate (MMA) and butyl acrylate (BA) monomers were synthesized by free radical copolymerization in toluene/methyl ethyl ketone solvent mixture. Batch polymerizations have been performed using different monomer feed c...

This work evaluates R-454C, R-459B, R-457A and R-455A as R-404A low-GWP substitutes in a stand-alone commercial refrigeration system for fresh product under ISO 23953-2. System is tested with and without receiver. Charge was optimized based on energy consumption tests in climatic chamber. A sign...

The equilibrium data of the thermal interconversion between a cyclopropylcarbonyl derivative with trispiro structure and a dihydrofuro[2,3-c]pyrazole have been examined.

Vascular endothelial growth factor (VEGF) plays important roles in tumor angiogenesis, and the inhibition of its signaling pathway is considered an effective therapeutic option for the treatment of cancer. In this study, we describe the design, synthesis, and biological evaluation of 2-acylamino...

Coomassie brilliant blue R250, an anionic dye is the most popular stain to detect proteins resolved in SDS-PAGE gels. Crystal violet, a cationic dye was found to be versatile and stained proteins in SDS-PAGE gels and in zymograms. Stained proteins can be transferred to nitrocellulose and the sta...
