Synthesis, Characterization and Copolymerization of N-(phenylamino)maleimide with MMA

E-Journal of Chemistry, 2007
The free radical copolymerization of N-(phenylamino)maleimide (N-PAMI) was carried. The copolymerization with methyl methacrylate (MMA) was performed at 65°C with AIBN as the initiator in THF solvent.

Bond-specific reaction kinetics during the oxidation of (111) Si: Effect of n-type doping

, 2010
It is known that a higher concentration of free carriers leads to a higher oxide growth rate in the thermal oxidation of silicon. However, the role of electrons and holes in oxidation chemistry is not clear.

Kinetic Isotope Effect in the Unfolding of a Protein Secondary Structure: Calculations for Beta-Sheet Polyglycine Dimers as a Model

Biomolecules
In the present work, we performed calculations of the kinetic isotope effect (KIE) on H/D, 14N/15N, 16O/18O, and 12C/13C isotopic substitution in the dissociation of beta-sheet polyglycine dimers of different lengths into two monomer chains.

Modelling acid attack of oilwell cement exposed to carbonated brine: effect of specimen geometry on experimental results [PDF]

, 2019
In recent years, the authors and co-workers have developed a diffusion-reaction model for the degradation process of oilwell cements exposed to carbonated brines in the context of CO2 capture and storage in abandoned oil reservoirs.

Optimization and Evaluation of Drying Kinetics and Quality Attributes of Persimmon Using Infrared Dryer: Influence of Operational Parameters [PDF]

Iranian Journal of Chemistry & Chemical Engineering
The impact of infrared drying parameters on drying time and the qualitative characteristics of the persimmon was thoroughly investigated by varying sample thickness (3, 5, and 7 mm), air velocity (0.5, 1.25, and 2 m/s), and infrared power levels (1000 ...
