Microstructural Evolution and Mechanical Properties of a Medium‐Manganese Steel Manufactured by Laser‐Based Powder Bed Fusion of Metals

open access: yesAdvanced Engineering Materials, EarlyView.
Fe–12Mn–0.2C medium‐manganese steel is processed by laser‐based powder bed fusion of metals using blended as well as pre‐alloyed powder. Various scanning speeds are used to determine the influence of energy deposition rate on microstructure and mechanical properties.

Stabilized Intermediate Phase Via Pseudo‐Halide Anions Toward Highly Efficient and Light‐Soaking Stable Perovskite Solar Cells

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.

Academic freedom as radical freedom

open access: yes, 2022
Krijnen discusses the relationship between universities and academic freedom against the background of the market-oriented contemporary state of universities and he develops what he terms as a 'humanity-focused argument' which he draws from the school of philosophical idealism in order to establish a conception of what a university is and how academic ...

Freedom to Fund [PDF]

open access: yesCell, 2007
Philanthropists are exerting an unmistakable influence on the research agenda, drawing attention to long-ignored research areas, promoting collaborations, and giving scientists the freedom to explore serendipitous ideas. Unbridled by politics or bureaucracy, philanthropic organizations can fund the riskier projects that could yield the biggest payoffs.

Poly(1,4‐anthraquinone) as an Organic Electrode Material: Interplay of the Electronic and Structural Properties due to the Unusual Lone‐Pair‐π Conjugation

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
In this study, the unique role of the unusual lone‐pair‐π conjugation mechanism in poly(1,4‐anthraquinone) (P14AQ) is explored as an organic electrode material. Unlike traditional π‐π interactions, P14AQ's conjugation involves lone pairs of oxygen atoms interacting with the π cloud of adjacent units, enabling stable charge transport even with minimal π‐
