A method is devised for the deposition of CuSCN on ruthenium bipyridyl dye coated nanocrystalline TiO2 films from a solution in n-propyl sulphide. The dye-sensitized solid state photovoltaic cell formed was found to yield higher short-circuit photocurrent, open-circuit voltage and efficiency com...

Long-lived radical cation dimers of diethyl sulfide, di-n-propyl sulfide and di-n-butyl sulfide have been prepared via an association reaction of the dialkyl sulfide radical cation with the dialkyl sulfide in the cell of a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer. Und...

The mechanism and kinetic aspects of the retro-ene reaction of the Allyl n-propyl sulfide and its deuterated derivative were studied using four different types of density functional theory methods with eight different levels of the basis sets. The activation energies were determined at 550.65 K....

A novel octa(propargyl propyl sulfide) POSS (OPPSP) was synthesized by the thiol-halogen reaction between octa(mercaptopropyl) POSS (POSS-SH) and propargyl chloride under phase transfer catalysis. Furthermore, OPPSP was employed as a reinforcing agent to prepare a modified silicon-containing ary...

Diethylene glycol (DEG) is a chemical compound used during offshore oil activities to prevent hydrate formation, and it may be released into the sea. A full ecotoxicological characterization is required according to European and Italian regulations for chemical substances. We have evaluated long...

Endocrine disrupting chemicals (EDCs) are known to disrupt normal metabolism and can influence the incidence of obesity in animals and humans. EDCs can exert adverse effects at low concentrations, often in a non-monotonic dose-related fashion. Among EDCs, Bisphenol A (BPA) is extensively used in...

The poor ability of many drugs to cross skin layers is the main limiting factor for the exploitation of the transdermal route for drug delivery. As a consequence, several approaches have been proposed to overcome the skin barrier, such as the inclusion of penetration enhancers in the topically a...

Densities and ultrasonic speed of ethylene glycol, diethylene glycol and triethylene glycol in (0.00, 0.01, 0.03, 0.05) mol kg−1 aqueous solutions of glycerol have been measured at T = (293.15, 298.15, 303.15, 308.15) K and experimental pressure p = 0.1 MPa. From the density data, the apparent m...

The use of a porous PTFE membrane (pore size = 0.2 μm) in the dehydration of diethylene glycol (DEG) by a vacuum membrane distillation (VMD) method was studied. Experiments on VMD for the treatment of 85 wt. % aqueous DEG were carried out at temperatures from 70 to 90°C, with stirring from 600...

In this work, the solid-liquid phase equilibrium for binary system of succinic acid + diethylene glycol at the temperatures ranging from (298.15 to 333.15) K and ternary system of (succinic acid + urea + diethylene glycol) at 298.15 K, 313.15 K and 333.15 K was built by using the isothermal satu...

A series of Cu/Zn/Al mixed oxides, as steam methanol reforming catalysts, were synthesized via the microwave assisted combustion synthesis method using diethylene glycol as the organic fuel. The nanocatalysts were analyzed by XRD, FESEM, EDX, BET, H2-TPR and FTIR techniques to ensure authenticit...

Diethylene glycol is a chemical that is readily available and has been implicated in multiple mass poisonings when used as a diluent in pharmaceutical preparations. Diethylene glycol is found commonly in various chemicals including automotive products and wallpaper stripper. It has two ethylene ...

A case of transcutaneous diethylene glycol poisoning with severe acute kidney injury, but a positive outcome, is described. A man without significant medical history was admitted to our hospital due to anuria, gastrointestinal symptoms, and hypertension. Ultrasonography excluded vascular damage ...

This study deals with improving the short-term aging resistance of bitumen with a new material, a diethylene glycol based polyboron compound (DEGPB). The compound was synthesized chemically and used 50/70 penetration grade bitumen. The bitumens are aged by means of Thin Film Oven Test (TFOT). Th...

A new ester of lasalocid with 2-allyloxyethanol (Las9) has been synthesised and its ability to form complexes with Li+, Na+, K+, Rb+ and Cs+ cations has been studied by ESI mass spectrometry as well as 1H, 13C NMR and FT-IR spectroscopic methods. The ESI-MS spectra indicate that Las9 forms stabl...

The immunotoxicity of 2,2′-dichlorodiethyl sulfide (sulfur mustard, SM), on humoral and cell-mediated immunity was compared with that of the nitrogen mustard 2-[bis(2-chloroethyl)amino]tetrahydro-2H-1,3,2-oxazophosphorine 2-oxide (cyclophosphamide, CP). SM and CP had similar effects on thymic a...

The chloromethyl groups of 2,2′-dichlorodiethyl ether and poly(epichlorhydrin) have been used to quaternize pyridine, and the quaternary compounds have been converted into simple and complex salts with TCNQ. The resistivities of these salts have been measured.
