Combining rival π‐space descriptions of O3 and of SO2

02-Feb-2016 | Fabio E. Penotti, David L. Cooper, International Journal of Quantum Chemistry, 2016

Two rival solutions have emerged from applications of spin‐coupled (SC) theory, also known as the full‐generalized valence bond (full‐GVB) approach, to the π system of O3. The lowest solution (SCd) corresponds to significant diradical character but there is a second solution (SCc) which lies ...

Multiway analysis applied to time‐resolved chemiluminescence for simultaneous determination of paracetamol and codeine in pharmaceuticals

02-Feb-2016 | Ali Mokhtari, Nastaran Jafari Delouei, Mohsen Keyvanfard, Mohammad Abdolhosseini, Luminescence, 2016

Abstract This method is based on the enhancing effect of codeine (COD) and paracetamol (PAR) on the chemiluminescence (CL) reaction of Ru(phen)32+ with Ce(IV). In the batch mode, COD gives a relatively sharp peak with the highest CL intensity at 4.0s, whereas the maximum CL intensity of the ...

Poly(lactic acid) fibers obtained by solution blow spinning: Effect of a greener solvent on the fiber diameter

01-Feb-2016 | Delne Domingos da Silva Parize, Juliano Elvis de Oliveira, Milene Mitsuyuki Foschini, José Manoel Marconcini, Luiz H ..., Journal of Applied Polymer Science, 2016

ABSTRACT Poly(lactic acid) (PLA) fibers has been obtained by solution blow spinning (SBS) using different solvents, however most of them are toxic and can be dangerous to human health or cause harm to the environment. Therefore, this work aimed to evaluate the use of dimethyl carbonate (DMC), ...

Preparation and characterization of poly(lactic‐co‐glycolic acid)/chitosan electrospun membrane containing amoxicillin‐loaded halloysite nanoclay

28-Jan-2016 | Sh. Tohidi, A. Ghaee, J. Barzin, Polymers for Advanced Technologies, 2016

The main attitude of new wound dressings with biocompatible natural or synthetic polymers is improving and accelerating the healing process. In this study, halloysite nanotubes (HNTs) loaded with a model antibiotic drug, amoxicillin (AMX), were incorporated within poly(lactic‐co‐glycolic acid) ...

Kinetics and mechanism of the reaction between 3‐methylbenzenediazonium ions and catechol

28-Jan-2016 | Katarzyna Jaszczuk, Anna Dudzik, Sonia Losada‐Barreiro, Marta Szymula, Jolanta Narkiewicz‐Michalek, Carlos Bravo‐Díaz, Journal of Physical Organic Chemistry, 2016

Abstract We have investigated the kinetics and mechanism of the reaction between 3‐methylbenzenediazonium, 3MBD, ions and catechol (1,2‐dihydroxybenzene, [CAT]) in aqueous buffer solution under acidic conditions by employing spectrometric UV/VIS. The variation of the observed rate constant, ...

Superhydrophobic ceria on aluminum and its corrosion resistance

27-Jan-2016 | Beibei Wan, Junfei Ou, Damei Lv, Mingshan Xue, Fajun Wang, Huiming Wu, Surface and Interface Analysis, 2016

Superhydrophobic ceria on the aluminum substrate was fabricated, and its corrosion resistance was investigated by different techniques. For example, the so‐obtained superhydrophobic sample was immersed into the NaCl aqueous solution, and the variations in the surface wettability as well as the ...

The thermal, optical, flame retardant, and morphological consequence of embedding diacid‐capped ZnO into the recycled PET matrix

27-Jan-2016 | Shadpour Mallakpour, Mashal Javadpour, Journal of Applied Polymer Science, 2016

ABSTRACT We extended our work to a fast and facile nanocomposites (NCs) manufacturing by incorporation of ZnO nanoparticles (NPs) on to a recycled poly(ethylene terephthalate) PET as a polymer matrix prepared by a dissolution/reprecipitation method. The surface of ZnO NPs was functionalized ...

Tributyltin(IV) Schiff base complexes with amino acid derivatives: synthesis, characterization and biological activity

26-Jan-2016 | Carlos Camacho‐Camacho, Irma Rojas‐Oviedo, Ariadna Garza‐Ortiz, Rubén Alfredo Toscano, Luis Sánchez‐Sánchez, Jorge C ..., Applied Organometallic Chemistry, 2016

The synthesis in one‐pot reactions and structural characterization of six new tri‐n‐butyltin(IV) derivatives of Schiff bases are reported. The compounds are derived from a condensation reaction between l‐alanine, l‐valine, l‐isoleucine, l‐methionine, l‐phenylalanine or l‐tryptophan and ...

Effect of pre‐treatment of sugarcane bagasse on the cellulose solution and application for the cellulose hydrogel films

26-Jan-2016 | Kazuki Nakasone, Takaomi Kobayashi, Polymers for Advanced Technologies, 2016

Sugarcane bagasse was used as a cellulose resource, and the transparent cellulose hydrogel films were obtained from the purified cellulose by phase inversion process without chemical cross‐linking, when the dissolved cellulose in lithium chloride/N,N‐dimethyl acetamide was transformed into the ...

Electron microscopic visualization of complementary labeled DNA with platinum‐containing guanine derivative

25-Jan-2016 | Alexandre Loukanov, Chavdar Filipov, Polina Mladenova, Svetlin Toshev, Saim Emin, Microscopy Research and Technique, 2016

ABSTRACT The object of the present report is to provide a method for a visualization of DNA in TEM by complementary labeling of cytosine with guanine derivative, which contains platinum as contrast‐enhanced heavy element. The stretched single‐chain DNA was obtained by modifying double‐stranded ...
