When does category spanning hurt or help producers?

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Scholars have theorized many factors shaping whether category spanning helps or hurts producers. We first synthesize evidence by meta‐analyzing 25 years of empirical research, which reveals a null effect of spanning on average, yet with significant subsample heterogeneity. To unpack it, we theorize and find that spanning hurts

Synthesis of Amorphous‐Crystalline Mixture Boron Nitride for Balanced Resistive Switching Operation

open access: yesSmall, EarlyView.
An amorphous–crystalline mixture BN (acm‐BN) is synthesized through low‐pressure chemical vapor deposition, achieving balanced resistive switching with low SET voltage and stable RESET. High‐resolution transmission electron microscopy reveals that BN films are fully amorphous at 930 °C, a mixed amorphous–crystalline phase is achieved at 990 °C.

Buchanan and the Social Contract: Coordination Failures and the Atrophy of Property Rights

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT James Buchanan advocated that societies should be based on a social contract. He rejected anarchy, seeing it as a “Hobbesian jungle” that calls for government intervention to maintain social order. He also opposed theories of spontaneous order. These views led to debates about the compatibility of Buchanan's works with classical liberalism and

Thermodynamic Modeling of Sn–C and Fe–Sn–C Systems for the Tramp Elements Control in Steel Production

open access: yessteel research international, EarlyView.
A CALculation of PHAse Diagrams thermodynamic modeling for Fe–Sn–C system is carried out. The model and the developed database can be used to calculate phase diagrams and thermodynamic properties of this system over wide temperature/composition range, and a part of a larger thermodynamic database for steel and alloy system, and effectively used to ...

HWTS 50 Tool Steel Tailored for Laser Powder Bed Fusion: Sliding Wear of Bare Surfaces and Nitriding Response in Comparison with 18Ni300 and AISI H13

open access: yessteel research international, EarlyView.
This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...

Press Hardening for Sustainable Lightweight Chassis Design in Heavy‐Duty Vehicles: A Material Performance and Life Cycle Assessment Approach

open access: yessteel research international, EarlyView.
The article explores how high‐strength steels and press hardening revolutionize lightweight chassis design for heavy‐duty vehicles. It reveals that press hardened steels combined with shot peening can cut weight by up to 34% and reduce environmental impact by 21%–32%.
