The properties of quaternary ammonium salt-type cationic trimeric surfactants (m-2-m-2-m, m represents the carbon atom number in alkyl chain lengths of 8, 10, and 12) and oppositely charged anionic monomeric surfactant, sodium n-octyl sulfate (SOS), were characterized by employing several techni...
The micellization of an aqueous solution of the surface active ionic liquid (SAIL), 1-butyl-3-methylimidazolium octylsufate (C4mim)(C8OSO3) and its interaction with an anionic polymer sodium polystyrene sulfonate, (NaPSS) were studied using conductimetry, tensiometry and fluorimetry. Surface ten...
The new halogenated metabolites cryptophomic acid (1), cryptodiol (2), and cryptotriol (3) and the known dihydro-isocoumarin derivative 4, were isolated from the marine-derived fungus Phoma sp.135. The structural elucidation of these compounds was achieved by extensive analysis of spectroscopic ...
We show here that the disodium salt of 2-acetyl-5-chloro-4- hydroxycarbonylmethylthiocyclopent-4-ene-1,3-dione (salt 2) inhibits tobacco mosaic virus (TMV)-induced infections in detached leaves of TMV-resistant (Xanthi-nc) and -susceptible (Samsun) varieties of Nicotiana tabacum L. Inoculation o...
A new, easy and rapid synthesis of γ‐dilactones is cis‐fused with a cyclopentenic ring via cyclization of 7‐chlorotriethylenic‐malonic acids. The key step implicates an intramolecular cyclization to a cyclopentenyl cation, according to an electrocyclic π2s + π2a conrotatory process. This ...
Previous research showed that acute exposure to dichloromethane (DCM) produced a selective reduction in peakN 30 of flash evoked potentials (FEPs) in rats. In contrast, acute exposures top-xylene or toluene selectively reduced FEP peakN 160 . The present experiments compared the ...
Excess molar volumesV E m at the temperatures 298.15 K and 308.15 K and normal atmospheric pressure for [x{ClCH 2 CH 2 CH 2 Cl or ClCH 2 (CH 2 ) 2 CH 2 Cl} + (1 -x)CH 3 CO(CH 2 ) q - 3 CH ...
This paper reports the application of hexamethyldisilazane–trimethylsilyl trifluoromethanesulfonate (HMDS–TMSOTf) for the simultaneous silylation of 3-monochloro-1,2-propanediol (3-MCPD) and 1,3-dicholoropropanol (1,3-DCP) in solid and liquid food samples. 3-MCPD and 1,3-DCP are chloropropanol...
This review is concerned with the role of the N,N ,N -trimethylethylenediamine group as a substituent at phosphorus atoms in different coordination and/or oxidation numbers. A few examples for silicon are also presented.Intramolecular donor-acceptor interactions between the nitrogen atom of t...
A new set of values for the molar heat capacities of N-(2-aminoethyl)piperazine (AEP) and N,N,N′-trimethylethylenediamine (tMEDA) and their aqueous mixtures over the whole range of compositions are reported in the present work. Molar heat capacities of ternary mixtures of each polyamine with pi...
We investigated the effects of five allyl esters, two aromatic (allyl cinnamate and allyl 2‐furoate) and three aliphatic (allyl hexanoate, allyl heptanoate, and allyl octanoate) in established insect cell lines derived from different species and tissues. We studied embryonic cells of the fruit ...
Hydroxyapatite (HAP), a well‐known member of the calcium phosphate family, is the major inorganic component of bones and teeth in vertebrates. The highly ordered arrays of HAP structures are of great significance for hard tissue repair and for understanding the formation mechanisms of bones and...
Hydroxyapatite (Ca 10 (OH) 2 (PO 4 ) 6 , HAP), as the major inorganic component of bones and teeth in vertebrates, is a very important biomaterial with high biocompatibility, nontoxicity and high thermal stability, thus, it has wide applications in various biomedi...
This paper looks at the interaction between natural limestone fillers and sodium oleate, a waterproofing agent used in rendering mortars, which, despite being water soluble is very effective as waterproofing in cement-based mortars at very low dosages. The present paper shows that the surfactant...
Di(2-ethylhexyl) maleate (DEHM) is a non-evaluated substance newly detected in the majority of the printed cardboard boxes used for food packaging. Concentrations in the board are often sufficient for a migration into food of around 1 mg/kg. This level was reached after storage over several mont...
A copolymer system with controlled hydrophilicity has been prepared through copolymerization technique and its capability as controlled drug release carrier is investigated. The effect of copolymer composition on water uptake, thermal properties, and morphology is reported. The water uptake incr...
A novel PSA formulation that incorporates a bio-sourced lignosulphonate has been proposed. A molecular dynamics simulation study is attempted to explore the effect of lignosulphonate addition on the adhesion, thermal and mechanical properties of a conventionally used acrylic PSA composed of 2-EH...
It still remains a concern to break through the bottlenecks of anionic polymerization of polar monomers, such as side reactions, low conversion and low temperature (–78°C). In this work, potassium tert‐butoxide (t‐BuOK) was chosen to initiate the anionic polymerization of 2‐ethylhexyl metha...
Large size (15mm diameter and 80mm length) organic material 2-hydroxypyridine single crystal has been grown using the double wall ampoule with nano translation by modified vertical Bridgman technique for the first time. Material of the grown crystal was confirmed by single and powder X-ray diffr...
We synthesized some Eu(III) complexes {[Eu(dpa)(α-pc)(CH3OH)]·2CH3OH} (1), {[Eu(dpa)(2-ap)(CH3OH)]·2CH3OH}(2) and {[Eu(dpa)(2-hp)(CH3OH)]·2CH3OH}(3) [dpa = dipicolinic acid; α-pc = α-picolinic acid; 2-ap = 2-aminopyridine; 2-hp = 2-hydroxypyridine]. The structural characterization of the c...
