Molecularly Dissipative Liquid Crystal Elastomer Foams for Impact and Vibration Attenuation

open access: yesAdvanced Functional Materials, EarlyView.
Liquid crystal elastomer foams integrate cellular deformation with mesogen reorientation to create a dual‐scale energy dissipation mechanism. Progressive pore collapse absorbs mechanical loads, while stress‐induced mesogen reorientation provides additional damping, resulting in reduced impact transmission and broadband suppression of vibrational ...

The impact of varieties of democracy on subjective well-being: Global evidence

open access: yesActa Psychologica
This paper investigates the effect of democracy on subjective well-being (SWB) using panel data from 144 countries from 2005 to 2020. SWB measures the evaluation of life satisfaction, positive and negative emotions. In addition, democracy is conceived as

Oxygen Evolution Electrocatalysts with Trinuclear, Mixed‐Valence Iron Motifs on Electronically Aligned Carbon Dots

open access: yesAdvanced Functional Materials, EarlyView.
Trinuclear iron oxo‐bridged catalytic ensembles stabilized by aspartic‐acid‐derived carbon dots provide an effective platform for alkaline oxygen evolution. Mixed‐valence charge balancing, inner‐sphere charge transport, and work‐function alignment within the N/O‐rich carbon framework promote cooperative Fe‐site chemistry and efficient OER ...

Liberal democracy

open access: yes, 2002
Throughout recent history, the political ideologies of I iberal ism and democracy have been closely associated with each other. Despite this common association, there is a continuing tension between the two sy stems.

Democracy, Liberalism and the Middle East : On the Universality of Liberal Democracy

open access: yes, 2008
Democracy promotion has become a ‘big business’ for foreign policy makers and is generally assumed to foster global peace, political liberty and prosperity. Democratization is closely linked to the process of state-building and liberal peace- building, and is often regarded as a universal ideal which guarantees peace and freedom.

Nanoamphizymes: Self‐Assembled Amphiphilic Enzymatic Nanomaterials for High‐Performance Biocatalysis and Biosensing

open access: yesAdvanced Functional Materials, EarlyView.
An amphiphilic GOx nanoamphizyme was constructed by covalently introducing hydrophobic PPNI linkers onto GOx, enabling spontaneous self‐assembly into tunable nanoparticles. Mild crosslinking further stabilized the assemblies and enhanced catalytic performance and stability.

Multidimensional‐Encoded High‐Fidelity Spectrometers With a Floating‐Base Bipolar Junction

open access: yesAdvanced Functional Materials, EarlyView.
A floating‐base bipolar junction photodetector enables multidimensional spectral encoding through synergistic gate‐ and drain‐bias modulation of interfacial barrier matching. The resulting complementary spectral responses form a diverse, weakly correlated response matrix, enabling robust and high‐fidelity spectral reconstruction even at sub‐nanoampere ...

Neuromorphic Devices for Extreme Environments: State‐Variable Reliability and Stabilization Strategies

open access: yesAdvanced Functional Materials, EarlyView.
Neuromorphic devices for extreme environments are interpreted through the physical states that store and process information. Radiation, temperature extremes, and vacuum can perturb vacancies, filaments, trapped charges, polarization, interfaces, and readout signals.

Democracias, ciudadanías y formación ciudadana.Una aproximación.

open access: yesRevista de Estudios Sociales, 2007
This article examines some ofthe ideas developed in Western culture around the political and social organization of democracy. It argues that the way we understand democracy today (the liberal model) by no means exhausts its different meanings or ...
