Balancing allocative and dynamic efficiency with redundant R&D allocation: The role of organizational proximity and centralization

Strategic Management Journal, EarlyView.
Abstract Research Summary Resource‐based‐view scholars have mainly examined two resource allocation approaches for competitive advantage in multiunit firms: resource sharing and resource redeployment. These approaches emphasize allocative efficiency—the optimal allocation of resources to maximize their current value. In technology‐intensive industries,

Kinetically Controlled Direct In Situ Photolithography of Perovskite Color‐Conversion Layers

Small, EarlyView.
Kinetically controlled direct in situ photolithography (KC‐ISP) enables high‐resolution patterning of micrometer‐thick perovskite color‐conversion layers. By regulating thiol–ene reaction kinetics and redistributing precursors within the polymer matrix, lateral curing is suppressed and spatially selective crystallization is achieved.

Dibenzofuran‐Modulated Narrowband Red MR‐TADF Emitters for BT.2020 OLEDs With Ultralow Roll‐Off and Long Lifetime

Small, EarlyView.
A materials‐to‐device strategy enabling high‐efficiency, longer‐lifetime narrowband red OLEDs. Dibenzofuran‐integrated BNO MR‐TADF emitters provide tunable red emission (611–633 nm) with high color purity. Exciplex‐assisted PSF devices achieve 31.6% EQE, <1% roll‐off at 5000 cd m−2, and LT90 584 h @ 5000 cd/m2.
