Families in venture capital

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary This exploratory paper introduces a new type of family business by studying the investment strategies of family‐managed venture capital funds (“Family VCs”) across a multi‐country setting. It shows that Family VCs are more likely to invest in (syndicate with) geographically proximate startups (investors), indicating a ...

Large‐Scale Distribution of Physical Data Using DNA‐of‐Things Technology in Newspaper Printing

open access: yesSmall, EarlyView.
DNA‐of‐things technology enables stable data storage in large‐scale newspaper printing, with successful retrieval of 37 kB of digital data from a single ink dot containing approximately 14 femtograms of DNA. ABSTRACT DNA represents a promising solution for high‐density and long‐term data storage. In this study, we explore the scalability and robustness

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

open access: yessteel 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

A Comparative Study of Directed Energy Deposition‐Arc and Casting: Enhancing Mechanical and Thermal Properties of Hot‐Work Tool Steels

open access: yessteel research international, EarlyView.
The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage

open access: yessteel research international, EarlyView.
This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...
