Using a combination of scanning tunneling microscopy (STM) and density functional theory calculations, we have studied the adsorption of tetracene on the Cu(1 1 0) (2 × 1)O substrate. At monolayer coverage the adsorbed molecules are in the flat-laying geometry with their long axis along the clo...

Adsorption structures of tetracene on the Ru(101¯0) surface has been investigated by means of ab initio density functional theory (DFT) calculations. Several adsorption geometries of tetracene on Ru(101¯0) were examined in details. The optimized structures have an adsorption energy of 4.23 eV ...

Adventitious root cultures of Anthemis nobilis were established from roots of in vitro plantlets. GC-MS analysis of the n-hexane extract of the root cultures revealed that they accumulated geranyl isovalerate, a compound which is generally not detectable in parental plants, and negligible amount...

ObjectiveThe aim was accomplished by a comparative analysis of the physicochemical properties of urethane-dimethacrylate (UDMA) monomers and their homopolymers with regard to the properties of basic dimethacrylates used presently in dentistry. The homologous series of UDMA were obtained from fou...

Gelation properties of the copolymers of styrene with various proportions of 14C labelled ethylene glycol dimethacrylate, tetraethylene glycol dimethacrylate and polyethylene glycol (MW = 400) dimethacrylate have been studied. The thermal copolymerizations were carried out in 15% (v/v) solution ...

Grafting of poly(triethylene glycol dimethacrylate) (poly(TriEGDMA)), onto chitosan by ceric ion initiation has been investigated. The grafting conditions were optimized by studying the effect of monomer and initiator concentrations as well as time and temperature. Products with lower grafting y...

Acrylate esters are applied in industrial and consumer products often associated with polymers and resins. The difunctional methacrylate, triethylene glycol dimethacrylate (TEGDMA), is also frequently included in dental composite materials. Recently, mutagenicity testing of the compound revealed...

ObjectiveBulk fracture is one of the primary reasons for resin-based dental restoration failures. To date, there has been no report on the use of polymerizable dental monomers with acceptable biocompatibility to develop a resin with substantial self-healing capability. The objectives of this stu...

Amphiphilic copolymers of N-vinylpyrrolidone and triethylene glycol dimethacrylate, synthesized by radical copolymerization at equimolar and unequimolar brancher and chain transfer agent ratios, as well as their precipitated fractions with given chemical composition and physico-chemical characte...

ObjectiveVarious protective effects of N-acetylcysteine (NAC) against triethylene glycol dimethacrylate (TEGDMA)-induced cell damage have been demonstrated, but so far there is no evidence on NAC direct monomer detoxification mechanism. Here, we hypothesized that NAC might reduce TEGDMA cytotoxi...

ObjectivesEarlier studies demonstrated that dental resin monomers lower cellular viability and provoke oxidative stress. Reactive oxygen species (ROS) formation has a key role in triethylene glycol dimethacrylate (TEGDMA) induced adverse reactions. In the present study the effects of TEGDMA on m...

ObjectiveDental pulp stem cells (DPSCs) can differentiate into tissue specific lineages to support dental pulp regeneration after injuries. Triethylene glycol dimethacrylate (TEGDMA) is a widely used co-monomer in restorative dentistry with adverse effects on cellular metabolism. Aim of this stu...

Oxidative stress (OS) plays crucial roles in triethylene glycol dimethacrylate (TEGDMA, a major component in dental resin)-induced apoptosis of dental pulp cells. Mitochondria are important target organelles for regulating the balance of OS, meanwhile, imbalance of the mitochondrial dynamic asso...

The polymer nanoparticles based on an amphiphilic copolymer of N-vinylpyrrolidone with triethylene glycol dimethacrylate downloaded by antitumor agents (binuclear nitrosyl complexes of iron) were produced.

Previously, we found that nine kinds of new morpholin-3-one derivatives could inhibit the growth of A549 lung cancer cells in a dose-dependent manner, but how they performed their function remained unknown. In this paper, we studied the effects of the three more effective morpholin-3-one derivat...

The equimolal CO2 solvent, 4 m 2-methylpiperazine (2MPZ)/4 m piperazine (PZ), was modeled in Aspen Plus® using the eNRTL thermodynamic framework. Data were regressed using binary interaction parameters. The sequential regression method was used starting from prior PZ and 2MPZ models. The model c...

Three series of novel 2-methylpiperazine derivatives were designed and synthesized using a fragment-assembly strategy. Among them, six compounds (13, 16, 18, 22, 33, and 36) showed potent activity against CCR5 comparable to that of the positive control, maraviroc, in calcium mobilization assay. ...

In this work, the absorption performance of potassium carbonate (K2CO3) promoted by 2-methylpiperazine (2-MPZ) was examined for CO2 capture by using a stirred cell reactor at temperatures between 303 and 323 K. The density, viscosity and loading capacity of K2CO3 + 2MPZ solutions were experiment...

With increasing of worldwide demand for natural gas, as one of the primary energy sources, the separation of CO2 from raw natural gas streams has caught high attention. Hollow fiber membrane contactors (HFMC) are known as the potential gas-liquid contactor for removal of CO2. In such systems, th...

2-methylpiperazine (2MPZ) and equimolar 2-methylpiperazine/piperazine (PZ) blends are attractive as they preserve most of the benefits of PZ and overcome its limitations of solid solubility. The CO2 absorption rate and vapor liquid equilibrium (VLE) of 4 m 2MPZ and 2.5 m/2.5 m 2MPZ/PZ were measu...
