Dynamics of hydrogen-like atom bounded by maximal acceleration
, 2012 The existence of a maximal acceleration for massive objects was conjectured by Caianiello 30 years ago based on the Heisenberg uncertainty relations. Many consequences of this hypothesis have been studied, but until now, there has been no evidence that ...

Development of polymer network of phenolic and epoxies resins mixed with linseed oil: pilot study [PDF]
, 2010 Epoxy resin was mixed with phenolic resins in different percentages by weight. Composite 40/60 means the proportion by weight of epoxy resin is 40 percent. It was found that only composites 50/50 and 40/60 could be cured in ambient conditions. Dynamic

Corrosion protection of carbon steel by an epoxy resin containing organically modified clay [PDF]
, 2007 This study focusses on the use of montmorillonite clay (MMT) treated with an organic compound (aminotrimethylphosphonic acid (ATMP)) and dispersed in an epoxy resin to improve corrosion protection of carbon steel.

Synthesis of an aromatic N-heterocycle derived from biomass and its use as a polymer feedstock
Nature Communications, 2019 Aromatic N-heterocyclic compounds are important chemicals, but produced from petroleum. Here the authors show a pyridazine-based compound 6-(4-hydroxy-3-methoxyphenyl)pyridazin-3(2H)-one, used as polymer feedstocks, can be synthesized by a Friedel-Crafts

Dynamics of trace metal sorption by an ion-exchange chelating resin described by a mixed intraparticle/film diffusion transport model. The Cd/Chelex case [PDF]
, 2017 The time-evolution of Cd2+ ion sorption by Chelex 100 resin was studied in batch experiments as a function of time, pH, ionic strength, stirring rate, mass of resin and initial metal ion concentration.

Adhesion between the Resin Shell and Composite Resin.
The Journal of Nihon University School of Dentistry, 1992 Adhesiveness between the resin shell and composite resin was examined. As the resin shell, SR-PE-ISOCETTE, made from thermosetting crown and bridge resin, was used. The shear bond strengths between the resin shell and photocurable composite resin bonded by various methods were measured after 1-day of immersion in water at 37 degrees C. Super-bond C & B
