Controlling Polystyrene Particle Distribution in Colloidal Lithography For Correlated‐Disorder Structures

open access: yesAdvanced Optical Materials, EarlyView.
Colloidal lithography is a low‐cost, simple and scalable technique to fabricate correlated‐disorder nanostructures for light‐trapping in solar cells. This work investigates the control of polystyrene particle distribution in colloidal lithography, highlighting the importance of particle surface functionalization as well as the ability to tune the ...

Heteroleptic Ag(I) Complexes Bearing Benzothiazole and Benzoxazole Ligands for Orange‐Red Light‐Emitting Electrochemical Cells

open access: yesAdvanced Optical Materials, EarlyView.
Light‐emitting Electrochemical Cells (LECs) are appealing electroluminescent devices with potential application in low‐cost, large‐area display technology and disposable devices. In the manuscript, a novel family of bright photo‐ and electro‐active heteroleptic silver(I) is presented and comprehensively investigated.

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

open access: yesAdvanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

A Critical Time Window of Neocortex Modulation for Remote Fear Memory in Rats and Humans

open access: yesAdvanced Science, EarlyView.
This study identifies a delayed consolidation window around 18 h after fear learning in the mPFC essential for remote fear memory. VTA dopaminergic input during this window sustains remote memory in rats, while non‐invasive stimulation of homologous human mPFC at the corresponding time selectively weakens remote but not recent fear memory, revealing a ...

Egyptian pyramid or Aztec pyramid: How should we describe the industrial architecture of automotive supply chains in Europe? [PDF]

open access: yes
This article questions a terminology that is frequently used to describe automotive supply chains’ industrial architecture. Since vertical disintegration became a trend in the 1980s, this architecture has been represented using the image of the pyramid ...

Gm26550 Modulates Learning and Memory by Increasing IGF1 mRNA Expression and Stability in Nrf2−/− Mice

open access: yesAdvanced Science, EarlyView.
The present study shows that Nrf2 directly binds to the Gm26550 promoter, thereby activating Gm26550 transcription and increasing its expression. Mechanistically, Gm26550 promotes IGF1 expression by functionally antagonizing miR‐26a‐5p‐mediated repression and sequestering the RBP KHSRP, thereby enhancing hippocampal neuronal synaptic plasticity and ...
