4D printing of fast‐responsive liquid crystalline elastomers for light‐driven actuators

Responsive Materials, EarlyView.
Combining 3D printing with responsive materials, known as 4D printing, enables the fabrication of smart structures with programmable actuation. This study presents a photoresponsive LCE ink for DIW, achieving millisecond‐scale activation under blue light.

Impact of Device Architecture on Proton Detection Efficiency in 2D Perovskite Thick Film Detectors

Small, EarlyView.
This work shows the role of device architecture in MeV proton detection with 2D perovskite thick (> 1 µm) films. A direct comparison between planar and stacked devices demonstrates that the stacked geometry achieves superior response by enabling more efficient charge collection and better exploitation of the active layer volume, ensuring stable and ...

Assessing Proton Radiation Hardness of Antimony Chalcogenide Solar Cells

Solar RRL, EarlyView.
This paper discusses the effect of proton radiation on the device performance of antimony chalcogenide solar cells. Sb2S3 and Sb2(S, Se)3 solar cells are exposed to two different proton energies (100 and 300 keV) with fluences ranging from 1011 to 1014 protons/cm2.

Anisotropic Hierarchical Assembly of C60 from One Dimensional to Three Dimensional via Thiolate‐Mediated van der Waals Epitaxy

Small Structures, EarlyView.
This work shows a thiolate‐mediated van der Waals epitaxial strategy that enables the growth of anisotropic C60 structures with tunable dimensionality on Au(111). By employing pentanethiol as a cohost species, we achieve precise structural control, yielding architectures from 1D C60 nanochains to 3D superstructures possessing an orthorhombic lattice ...

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Errors in reconstruction of dichroic X‐ray orientation tomography due to polarization rotation of the incident beam

Journal of Synchrotron Radiation, EarlyView.
Linear dichroic X‐ray tomography is a technique in which the linear dichroism of anisotropic materials is used to image crystal orientation in three dimensions. We show that the reconstruction of tomograms is subject to errors due to the change in polarization on propagation through the material and propose strategies for mitigating these effects ...

On the astronomical orientation of the Hardknott Fort

, 2017
Among the remote Roman forts, which were situated at extreme points of the Empire, we find the Hardknott Fort. Located on the western side of the Hardknott Pass in the English county of Cumbria, this fort possesses a remarkable symbolic layout, as we have shown in a previous article (Philica, Article n.442).

China's Strategic Approach to Tech Diplomacy in a Time of Global Uncertainty

Global Policy, EarlyView.
ABSTRACT In the wake of U.S.‐China technological competition and the COVID‐19 pandemic, “tech diplomacy” has gained prominence in Chinese political and academic discourse. This concept is often ideologically framed to critique Western hegemonic narratives perceived as hindering China's technological advancement.

Cerebrovascular Function in Women With Polycystic Ovary Syndrome: A Pilot Multi‐Parameter Magnetic Resonance Imaging Study

Clinical Endocrinology, EarlyView.
ABSTRACT Objective Polycystic ovary syndrome (PCOS) is associated with an increased risk of cerebrovascular disease, but the effects on cerebrovascular function are unknown. In this pilot study, we sought to compare cerebrovascular perfusion, pulsatility, reactivity and metabolism between women with PCOS and healthy volunteers using MRI, and ...
