The study of solidarity and the social theory of Alain Touraine [PDF]

open access: yes, 1996
This chapter is a critical assessment of the study of Solidarity carried out by Alain Touraine and his research team in 1981 and first published in French in 1982 and in English in 1983. The book (Touraine et al.

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

open access: yesAdvanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Media transformation and new practices of citizenship: the example of environmental activism in South Durban [PDF]

open access: yes, 2002
South African media and telecommunications have been fundamentally restructured in the last decade. Corporate unbundling and black economic empowerment have transformed the ownership of broadcasting, print media, publishing, and telecommunications; new ...

Hybridized Charge‐Transfer Window within a Fully Conjugated Multi‐Resonance Thermally Activated Delayed Fluorescence Framework for Ultrafast Reverse Intersystem Crossing and High‐Efficiency in Deep‐Blue Organic Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
A hybridized charge‐transfer window combining short‐range and long‐range charge transfer is realized within a fully conjugated multi‐resonance thermally activated delayed fluorescence framework. The resulting excited‐state hybridization minimizes the singlet–triplet energy gap (0.04 eV) and enables ultrafast reverse intersystem crossing (krISC = 2.1 ...

Hydro‐Torsional Compaction for Scalable Production of Aramid Nanofiber Threads with Densely Assembled Double‐Helical Nanostructures

open access: yesAdvanced Materials, EarlyView.
This paper introduces a scalable strategy for producing hierarchically aligned PBDT threads through wet‐spinning, controlled drawing, and post‐spinning twisting. Ionic crosslinking reinforces structural stability, whereas alignment and twisting optimize mechanical performance.

Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems

open access: yesAdvanced Materials Technologies, EarlyView.
Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.

Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing

open access: yesAdvanced Materials Technologies, EarlyView.
Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the
