1,2-Bis(2,4,6-tribromophenoxy)ethane (BTBPE) is currently one of the most commonly applied novel brominated flame retardants. In this contribution, we analyze in detail the mechanisms pertinent to its thermal decomposition in view of analogous experimental findings. We demonstrate that a 1,3-hydrogen shift, leading to 2,4,6-tribromophenol (M9) and 1,3,5-tribromo-2-(vinyloxy)benzene (M10) molecu...

The ubiquitous nature of certain viral exanthematous diseases, particularly varicella and rubeola, results in the occasional occurrence of these illnesses in patients with disorders of a more chronic character (Gordon, 1962). This fortuitous association offers an opportunity to detect possible reciprocal influences and presents clinical problems, the solution of which may lead to a better under...

We have employed a classical molecular dynamics simulation for the direct pick-up reaction of adsorbates by very low energy (1-60 eV) ions scattered at a surface. The system investigated is the reactive ion scattering (RIS) of Cs+ with an adsorbate on a Pt(111) surface. The ion-dipole attraction between the projectile and the physisorbed adsorbate drives the abstraction reaction, in which the i...

The adsorption of a model nerve agent, O,S-dimethyl methylphosphonothiolate (DMPT), on the hydroxylated and unhydroxylated nano-crystalline magnesium oxide surface followed by the nucleophilic attack of ammonia (NH3) is investigated at the M06-2X/6-311++G(d,p) level of theory using the representative cluster models. The geometries of DMPT and NH3 are fully optimized, while the geometry of the o...

A feature scale simulator for atomic layer deposition (ALD) is presented that combines a Boltzmann equation transport model with chemistry models. A simple but instructive chemistry is considered; one reactant species adsorbs onto the surface, and a second reactant reacts with it from the gas phase (Eley–Rideal). This work includes potential desorption of the adsorbed species during purge steps...

8 Kinetics of the catalytic dehydration of 1-butanol to di-n-butyl ether (DNBE) over 9 Amberlyst-70 was investigated. Experiments were performed in liquid phase at 4 MPa and 10 413-463 K. Three elementary reaction mechanisms were considered: a Langmuir‐Hinselwood‐ 11 Hougen‐Watson (LHHW) formulation; an Eley-Rideal (ER) formulation in which DNBE 12 remains adsorbed; an ER formulation in which w...

In recent years, due to improvements in calculation methods and increased computer power, it has become possible to perform first-principles investigations for ‘simple’ chemical reactions at surfaces. We have carried out such studies for the catalytic oxidation of CO at transition metal surfaces, in particular, at the ruthenium surface for which unusual behavior compared to other transition met...
