Screening Surface Modifications to Benzene to Improve Solubility in Hydroxyl‐Terminated Polybutadiene (HTPB)—A DFT Demonstration

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT The objective of this paper is to demonstrate the advantage of computationally pre‐screening surface‐modifying material candidates, using density functional theory (DFT), to inform experimental synthesis and formulation efforts. This demonstration focuses on improving the solubility of benzene‐based materials in hydroxyl‐terminated ...

The role of identification in data‐driven policy iteration: A system theoretic study

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

Who Can Afford to Fail? Investigating Science Students' Perceptions of Failure Through the Lens of Their Identities

open access: yesScience Education, EarlyView.
ABSTRACT Scientists agree that learning to cope with failures is an important skill for science students to develop, and students who participate in science research often have positive outcomes after coping with science failures. However, the experience of failure in undergraduate science education more broadly seems to have an overall negative impact

What Do We Mean When We Say Epistemic Agency? How Considering Multiple Facets of Epistemic Cognition Can Clarify a Murky Theoretical Construct

open access: yesScience Education, EarlyView.
ABSTRACT Opening space for students to help shape knowledge building practices in the classroom—that is, epistemic agency—is necessary to achieve a variety of goals held by the science education community. As such, many scholars have explored how students might be positioned with, perceive, and take up epistemic agency.
