Monolithic nanocomposites of silica aerogels with hydroxy-terminated poly(dimethylsiloxane) (PDMS(OH)) were prepared by reactive supercritical deposition technique. The depositions were performed by using PDMS(OH) having two different molecular weights (Mn = 2750 g/mol and 18,000 g/mol) and at t...

The effect of hydrogen addition on silica growth in burner-stabilized methane/air flames with trace amounts of hexamethyldisiloxane are reported. Profiles of the aggregates' radius of gyration Rg and monomer radius a versus residence time were measured by laser light scattering. Experiments...

Mictrostructured silicon oxide (SiOx) thin films were deposited on glass and metal substrates from 1,1,1,3,3,3-hexamethyldisilazane (HMDSN) and hexamethyldisiloxane (HMDSO) by using atmospheric-pressure thermal microplasma jet. Two kinds of string-like products, randomly bent string-like product...

In this study, the effect of amylose content and cold plasma treatment on starch films properties was investigated. Films from normal (30%) and high amylose (50 and 70%) starches were subjected to hexamethyldisiloxane (HMDSO) cold plasma treatment. Morphological, structural, mechanical and barri...

The ionization cross section of hexamethyldisiloxane (HMDSO) molecules (m/z = 162), pentamethyldisiloxane radicals (m/z = 147) and tetramethyl hydro disiloxane radicals (m/z = 133) have been measured versus electron energy up to 30 eV. The radicals are produced selectively by two different mecha...

We demonstrated the feasibility to fabricate two-terminal non-volatile-memory (NVM) devices using pulsed radio frequency (rf) plasma polymerization and simple solution route. The two-terminal NVM devices were fabricated based on a metal-insulator-metal structure consisting of graphene quantum do...

A superhydrophobic thin film was deposited on an aluminium oxide substrate by low pressure plasma polymerization of hexamethyldisiloxane (HMDSO). The coating was determined to be superhydrophobic due to its high water contact angle (∼158°) and low contact angle hysteresis. The aim of this work...

Fragment ions produced from hexamethyldisiloxane (HMDSO) with a hot tungsten wire in a Freeman-type ion source were studied using a low-energy mass-selected ion beam system. The mass numbers of the fragment ions were identified. Although the chemical formulae of these fragments were not complete...

An empirical fundamental equation of state correlation in terms of the Helmholtz energy is presented for hexamethyldisiloxane. The relatively small amount of thermodynamic data that is available in the literature for this substances is considerably extended by speed of sound measurements and num...

A thermal stability test-rig for organic Rankine cycles working fluids was designed and commissioned at the Laboratory of Compressible-fluid dynamics for Renewable Energy Applications (CREA Lab) of Politecnico di Milano, in collaboration with the University of Brescia. The set-up is composed by ...

Three-layered zinc phosphites containing single monoamine molecules with different roles have been synthesized using hydro(solvo)thermal methods and characterized by single-crystal X-ray diffraction, thermogravimetric analysis, and infrared spectroscopy. Compound 1, (C8H17NH3)4Zn3(HPO3)5·3H2O, ...

This work focused on sex differences in rats exposed to sarin. Females were found to be more sensitive to sarin toxicity (LD50 67 μg/kg) than males (88 μg/kg), showed less acute hypothermic effects than males (at 120 min post sarin, 3.1 ± 1.1 and 4.5 ± 1 °C decrease, respectively), but with...

The efficacy and pharmacokinetics of the aqueous co-formulation contents of the Trobigard™ (atropine sulfate, obidoxime chloride) auto-injector were evaluated in a sarin exposed guinea pig model. Two subcutaneous (sc) sarin challenge doses were evaluated in guinea pigs instrumented with brain an...

A common consequence of exposure to organophosphate nerve agents is the centrally mediated seizure activity that appears even after conventional treatment with atropine and oximes. We have previously demonstrated a major inflammatory response with subsequent brain damage which was correlated wit...

Sarin is an organophosphorus compound, poisonous and deadly, which is used in the preparation of chemical weapons. We are looking for materials for using as sensing and capturing of Sarin, so the effect of Li, Ti, Fe and Ni single atoms on the structural and electronic properties of graphyne (GY...

Ion bombardment on graphene sheets can produce atomic vacancies that can trap metal atoms. In this paper, we demonstrated that these trapped metal atoms can effectively bind other molecules with heteroatoms, making them chemisorbed to the graphene. The trapped cobalt atom can bind sarin molecule...

BackgroundWe investigated the relationships between serum choline and betaine levels with metabolic syndrome-related indices in the general population of Newfoundland.

Reactions of hexafluoro-1,4-naphthoquinone with phosphorus-centered bis-phenylphosphanes with structure Ph2P(CH2)nPPh2 (where n = 1–5) and Et2P(CH2)2PEt2 in various solvents (anhydrous C6H6, aq. C6H6, aq. dioxane, aq. DMSO, or MeOH) were investigated. It was shown that the use of aqueous dioxan...

Betaine-based polyfluoroalkyl surfactants are major perfluoroalkyl and polyfluoroalkyl surfactants (PFASs) found in many aqueous film-forming foams (AFFF) impacted sites, while the transport behavior (i.e., mobility and adsorption) of PFAS-based betaines in groundwater and natural geosorbents in...
