Batch Heterogeneous Catalytic Selective Hydrogenation of Vegetable Oils Over Lindlar Catalyst: Kinetic Modeling Supported by Reaction Mechanisms

open access: yesChemistryOpen, EarlyView.
Heterogeneous catalytic selective hydrogenation of vegetable oils was modeled by Hougen–Watson approach to obtain kinetic rate laws. Parameters were obtained by nonlinear regressions on batch experimental data, and the best mechanism to interpret those experimental data was chosen on a statistical basis (higher coefficient of determination R2) and by ...

Investigating the Effects of Functionalized Single Wall Carbon Nanotubes on the Cure Behavior of a Carbon/Epoxy Prepreg System by an Optimized Parameter Approach

open access: yesPolymer Composites, EarlyView.
Mathematical Modeling of the Effect of Carbon Nanotubes on the Cure Behavior of a Carbon/Epoxy Prepreg Syste. ABSTRACT Carbon/Epoxy composite materials are used in a wide range of applications due to their superior performance. However, their properties are strongly related to cross‐linking reactions occurring during the curing process, and a prior ...

Unraveling the Link Between n‐Back Working Memory and Algebraic Ability in Adolescents: Correlations and Training Effects

open access: yesPsyCh Journal, EarlyView.
ABSTRACT Individuals with higher working memory capacities excel in mathematics performance. However, limited research has explored the impact of working memory on adolescents' algebraic ability and the transferability of training effects. Therefore, we conducted the current investigation with Chinese adolescents. In a correlational study (n = 218), we

Exploration of the Predictive Validity of Middle School Math Screeners

open access: yesPsychology in the Schools, EarlyView.
ABSTRACT Universal screening is a key element of multi‐tiered systems of support. Relative to literacy, fewer studies have investigated the psychometric properties of math assessments particularly amongst middle school students. We investigated whether outcomes from two types of curriculum‐based measures (CBMs), computational fluency (M‐COMP) and ...
