Platform competition and strategic trade‐offs for complementors: Heterogeneous reactions to the entry of a new platform

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary We study how the entry of a rival platform affects the strategies of the incumbent's complementors. The latter face a trade‐off: While the entry threatens their benefits from indirect network effects, it also allows them to escape intense within‐platform competition.

Spontaneously Formed Orientation Polarization Thin Films for Engineering Organic‐Organic Interfaces

open access: yesSmall, EarlyView.
Asymmetric molecular interactions at the film surface during vacuum deposition facilitate the spontaneous formation of orientation polarization of polar molecules. Well‐designed polar molecules form significantly strong film polarizations, which can be used as dipolar interlayers to enhance the photovoltaic properties of heterojunction‐type organic ...

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

open access: yesStructural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Strip loading in steel fiber reinforced concrete: Experimental and theoretical investigation

open access: yesStructural Concrete, EarlyView.
Abstract Fiber reinforced concrete is becoming increasingly popular in engineering practice due to its high robustness, post‐cracking behavior, and crack control. For strip loading, as common, for example, in longitudinal joints of tunnel lining segments, the use of fiber reinforced concrete has the potential to reduce conventional reinforcement ...

Experimental and theoretical investigation of longitudinal tunnel lining joints with confining reinforcement

open access: yesStructural Concrete, EarlyView.
Abstract Precast reinforced concrete segmental linings are frequently used in modern tunneling. In these linings, the longitudinal joints typically have a reduced contact cross‐section and thus often govern the design, particularly in tunnels under high hydrostatic pressure or crossing squeezing or swelling ground with correspondingly high ...
