Open Access, Innovation, and Research Infrastructure
Publications, 2016 In this article we argue that the current endeavors to achieve open access in scientific literature require a discussion about innovation in scholarly publishing and research infrastructure. Drawing on path dependence theory and addressing different open

Advanced Engineering Materials, EarlyView.Nickel‐based alloys are widely used in high‐temperature applications due to their excellent mechanical strength and oxidation resistance. However, properties such as high‐temperature strength and pronounced work‐hardening make them difficult to machine.

Advanced Engineering Materials, EarlyView.The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Research on Diamond Open Access in the Long Shadow of Science Policy
PublicationsThis review paper reviews research literature on Diamond Open Access (DOA) journals—sometimes also called Platinum Open Access—that was produced after this journal segment started to become a priority in European research policy around 2020.

Small firms, borrowing constraints, and reputation [PDF]
, 1995 This paper presents a simple model relating firm age with firm size and access to credit markets. Lending to new firms is risky because lenders have had no time to accumulate observations about them.

Advanced Engineering Materials, EarlyView.Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

EludamosPlaying on the double-meaning of the abbreviation DOA as referring to both diamond open access and dead-on-arrival, the editorial presents the rationale, politics, and not least severe challenges connected to Eludamos’s radical open access practices ...

Advanced Engineering Materials, EarlyView.This study investigates thermo‐chemical processes during high‐temperature testing of two commercial MgO‐C brick grades, one containing 47.5 wt.% MgO‐C recyclate. Using ETV, DTA/TG‐MS, XRD, and SEM/EDS/EBSD, mechanisms such as carbothermal reduction of magnesia, impurity incorporation into the secondary MgO surface layer, and calcium‐rich phase ...
