Big Tech in Taiwan

This report examines how 17 leading U.S. technology companies are economically and operationally entangled with Taiwan. By mapping investments, R&D efforts, data centers, and supply chains, it sheds light on how these ties could influence corporate behavior in a future conflict with China, and what risks and incentives may shape tech companies ...

Photoelectric‐Coupled Ferroelectric Heterojunctions for Ultrahigh NO2 Sensing With Polarization‐Memory‐Assisted Interfacial Modulation

Advanced Science, EarlyView.
This study demonstrates a Bi2WO6/SrBi2Ta2O9 heterojunction where light‐driven ferroelectric polarization reversal couples with persistent photoconductivity, enabling exclusive NO2 selective room‐temperature sensing. The device achieves a two‐order‐of‐magnitude sensitivity enhancement over an unpolarized device, a sub‐ppb detection limit, and robust ...

Femtosecond‐Laser‐Induced Physical Unclonable Random Maze Structure for Storage‐Free Encryption

Advanced Science, EarlyView.
Femtosecond‐laser‐induced gold random maze structures serve as multimodal physical unclonable functions for storage‐free encryption. Their stochastic optical, electrical, and Raman responses are generated by plasmon‐assisted Marangoni formation and converted into AES‐compatible keys without permanent secret‐key storage, offering a portable route toward

Mechanistic Understanding of Protein–MOF Integration Through Surfactant‐Driven Interfacial Design

Advanced Science, EarlyView.
This study reveals how surfactant‐driven interfacial design governs the assembly and stability of protein@MOF composites. Using lipid‐based nonionic surfactants, we modulate protein–MOF interactions to improve encapsulation efficiency, MOF crystallization, and catalytic performance.

History in the making: Whistleblowers and big tech

First Monday
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 ...

Adaptive Coordination Engineering for Efficient and Robust H2 Release

Advanced Science, EarlyView.
β‐H elimination is a pivotal but challenging step in homogeneous formic acid dehydrogenation reactions due to strict hydride‐metal matching. By using a rationally designed Pd1Ag2 bimetallic system with adaptive Pd1‐Ag2/L2 coordination and formate bridges, it enables boosted formic acid dehydrogenation under ambient air (7.7 times higher than a Pd ...

Big Tech in Österreich

‘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.
