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 ...

A mineral reconnaissance survey of the Abington-Biggar-Moffat-area, south-central Scotland [PDF]

open access: yes, 1979
Panned heavy mineral concentrates, mostly obtained from stream sediments, were collected from 195 sites in the Abington-Biggar-Moffat area. The project area, which lies immediately east of the formerly important mining district of Wanlockhead ...

Subnanometric Platinum–Germanium Clusters for Efficient Propane Dehydrogenation Catalysis

open access: yesSmall, EarlyView.
Pt─Ge alloy clusters are regioselectively encapsulated within the sinusoidal channels of pure silica MFI zeolite (PtGe@MFI). The developed Pt─Ge alloy clusters exhibit exceptional performance with 36‐fold higher activity than the most stable catalyst ever reported and twice its stability, and with comparable activity to and 21‐fold higher stability ...

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 ...

Trace Element Composition of Stream Sediments an Integrating Factor for Water Quality [PDF]

open access: yes, 1975
Bottom sediments, suspended sediments, and water were sampled along 130 miles of the Buffalo River in northern Arkansas. The water and acid extracts of the suspended sediments and the minus 95 mesh fraction of the bottom sediments were analyzed by atomic

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 ...
