Students’ Experiences of Teachers’ Ways of Unpacking Visual Representations in the Context of Intermolecular Forces

open access: yesScience Education, EarlyView.
ABSTRACT This is the third article in a series, emanating from a project that used social semiotics and phenomenography to explore the role visual representations play in the teaching and learning of chemistry. Building on our earlier work that identified five qualitatively different ways that teachers may use to unpack visual representations in their ...

Who gets redeployed? Inventor characteristics and resource redeployment decisions

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary While the literature highlights the benefits of internally redeploying resources, there is less empirical guidance on which resources are most likely to be redeployed. We examine the relationship between inventor characteristics and redeployment decisions, motivated by the tension between costs and benefits of keeping a ...

Toward Efficient and Reliable Chemical Upgrading Using Solid Oxide Electrochemical Reactors, Mechanisms, Challenges, and Design Principles

open access: yesSmall, EarlyView.
Solid oxide electrochemical reactors (SOERs) offer a compelling pathway for coupling renewable electricity with chemical manufacturing, but their real application is still limited by low efficiency and instability. This review systematically summarizes SOER reaction mechanisms, performance‐limiting factors, and recent progress toward high‐efficiency ...

Microscopic seepage simulation of gas and water in shale pores and slits based on VOF

open access: yesOpen Physics
The microscopic pore-fracture structure and wettability have a significant influence on the two-phase seepage of shale gas and water. Due to the limitation of experimental conditions, the seepage patterns of gas and water in shale pores and slits under ...

Forgoing Nuclear: Nuclear Power Plant Closures and Carbon Emissions in the United States

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT This paper examines the effect of nuclear power plant decommissioning on electricity generation and carbon emissions in the United States. Using data on nuclear reactor closures in the United States between 1993 and 2022 and data on state‐level carbon emissions and electricity generation from the Energy Information Administration (EIA), this ...

THE PELLETS APPLICATION IN LABORATORY RESEARCHING OF INHIBITIVE MUD/SHALE INTERACTION

open access: yesRudarsko-geološko-naftni Zbornik, 2012
Wellbore instability appears to be a serious problem during drilling process through shale. Shales instability cause basically comes out of its mineralogical composition (especially clay minerals content) and physico-chemical properties.

Regulation, Taxation, and Resources: Unpacking Greenhouse Gas Emission Drivers Across G7 Economies

open access: yesThunderbird International Business Review, EarlyView.
ABSTRACT Advanced economies are under growing pressure to downscale greenhouse gas (GHG) emissions without undermining growth, yet G7 (Group of Seven) nations, representing almost 10% of the world's population, still generate one quarter of global GHGs.
