From Interest to Intention: Factors Shaping Black Boys’ STEM Career Expectation in Early Adolescence

The Career Development Quarterly, EarlyView.
ABSTRACT This study examines the predictors of STEM career expectation among Black boys in ninth grade using nationally representative data from the High School Longitudinal Study of 2009. Guided by social cognitive career theory, we analyze associations between math and science self‐efficacy, career exploration activities, and STEM career expectation ...

Accurate Molecular Size Determination by Diffusion Ordered NMR Spectroscopy Based on an Improved Diffusion Model

Chemistry – A European Journal, EarlyView.
A semi‐empirical Stokes‐Einstein‐based model for describing the diffusion of organic, organometallic and coordination compounds is developed for the interpretation of diffusion constants obtained by diffusion‐ordered NMR spectroscopy (DOSY). This model uses the molecular volume as a descriptor and shows a high accuracy, enabling application to ...

Assessment of Gibbs Free Energy Calculation in PI‐Controlled Heating

Chemie Ingenieur Technik, EarlyView.
For description and control of chemical processes in lab or industry thermodynamic variable Gibbs free energy provides opportunity to compare and interpret phenomena, even on a quantitative level. In a case study for PI‐controlled heating, impacts on its limits from control delay until parameter quantization are highlighted and assessed.
