How digital platforms affect local entrepreneurial activities: Evidence from the staggered entry of craigslist

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Access to markets is critical for entrepreneurial success, yet many face significant barriers. This study argues that digital platforms functioning as peer‐to‐peer marketplaces can facilitate entrepreneurial activity by improving market access for new ventures.

Influence of Steel Recycling on Phase Transformation in Medium‐Manganese Third‐Generation Advanced High‐Strength Steels

steel research international, EarlyView.
On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.

Recycling‐Induced Copper Contamination of a 42CrMo4 Quench and Tempering Steel—Scaling and Susceptibility to Hot Shortness

steel research international, EarlyView.
In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can
