Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

Strategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

Rounded Monodisperse Fluorescent Nanodiamonds

Small, EarlyView.
Nanodiamond (ND) shape control using rapid molten‐nitrate etching is studied as a scale‐up method for monodispersed rounded particles. Optimal etching condition (567°C for 6 min) yields NDs with atomically stepped surfaces and reduced sp2 content. Compared to angular control, rounded NDs exhibit an increased proportion of luminescent particles (66% vs.

Role of 1D and 2D Materials in Achieving Transparent and Flexible Lithium‐Ion Batteries for Wearable Electronics

Small, EarlyView.
Hybrid 1D–2D architectures redefine material design strategies for TFLIBs by decoupling competing performance parameters. This approach accelerates the transition of TFLIBs from proof of concept to practical wearable technologies. ABSTRACT Transparent and flexible lithium‐ion batteries (TFLIBs), enabled by advanced nanomaterials and flexible ...

Unbiased Tandem System for Simultaneous Methane and Glycerol Upgrading to Formic Acid Under Ambient Conditions

Small, EarlyView.
A bias‐free photovoltaic‐photoelectrochemical tandem system enables simultaneous methane and glycerol upgrading to formic acid under ambient conditions. The cathode generates hydrogen peroxide for methane oxidation, while the photoanode efficiently oxidizes glycerol.

Hierarchically Engineered Nanocellulose‐Halloysite Composite Foams for Integrated Thermal Insulation and Intrinsic Fire Resistance

Small, EarlyView.
Hierarchically engineered cellulose‐based nanocomposite foams integrate thermal insulation, mechanical robustness, hydrophobicity, and intrinsic flame retardancy. A multiscale hybrid network enables efficient heat and mass transport suppression, promoting char formation and self‐extinguishing behavior without toxic additives.
