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

Small, 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

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.

The effect of processing route on properties of HfNbTaTiZr high entropy alloy [PDF]

, 2019
High entropy alloys (HEA) have been one of the most attractive groups of materials for researchers in the last several years. Since HEAs are potential candidates for many (e.g., refractory, cryogenic, medical) applications, their properties are studied ...

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

Thermal exchange effects on steel thixoforming processes [PDF]

, 2010
Steel thixoforging is an innovative semi-solid forming process. It allows the manufacturing of complex parts and minimises the forming load. This work aims to identify and characterise the main feature zones of a thixoforging part.
