Purposive doping of low electronegative Ba2+ (0.89) at La3+ (1.1) site in LaFe0.7Ni0.3O3‐δ induces the formation of a tri‐phase composite, which shortens Fe─O bond and lowers activation energy, thereby significantly improves electrical conductivity and catalytic activity, and finally offers a record‐high peak power density in La0.5Ba0.5Fe0.7Ni0.3O3‐δ ...

Molecular dipole engineering in dendritic perylene diimide polymers through nitrogen‐rich heterocyclic linkers amplifies the built‐in electric field, enabling sub‐picosecond charge separation and efficient multi‐electron accumulation. This structure–dynamics–performance relationship establishes a versatile design strategy for high‐performance organic ...

History in the making: Whistleblowers and big tech
The recent history of computing has been drafted in the press as the story of corporations and the men who lead them. Another story, reported on widely but often less explicitly connected by the general public to the progress of computing history is the story of the people — mostly women, and mostly women of color — who have been engaged in various ...

Tumor‐Infiltrating mregDCs Restrain Anti‐Tumor Immunity in Early Relapse HCC
Tumor‐infiltrating mregDCs are regulated by the TNFR2‐non‐canonical NF‐κB axis, which is mediated by TNF‐α secreted by CD161+CD8+ T cells. These mregDCs recruit CD161+CD8+ T cells via the CCL20‐CCR6 axis, forming a positive feedback loop that enhances immunosuppression, promotes early recurrence of HCC, and further confirms TNFR2 as a key therapeutic ...

‘Big Tech’ hat die Welt grundlegend verändert. Wir profitieren von Big Tech durch eine Reihe neuer Technologien und Dienste, die oft unentgeltlich – allerdings gegen Preisgabe persönlicher Daten – angeboten werden. Viele sehen den Einfluss von Big Tech auf Bereiche des täglichen Lebens aber auch mit zunehmender Skepsis.

The configurational‐entropy strategy enables rapid and sensitive ethanol detection using a multicomponent oxide. The high‐entropy (InSnFeZnW)Ox provides enriched oxygen vacancies and diverse adsorption sites that strengthen surface reactivity. The sensor achieves a 5135% ethanol response with fast kinetics and stable long‐term operation.
