Ultrafast Room‐Temperature Nanofabrication via Ozone‐Based Gas‐Phase Metal‐Assisted Chemical Etching for High‐Performance Silicon Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
Ozone‐based gas‐phase metal‐assisted chemical etching enables unprecedented room‐temperature fabrication of high‐quality silicon nanowires. The superior oxidation potential of O3 drives rapid vertical etching (1 µm min−1) while maintaining exceptional structural integrity. The pristine nanowire surfaces enable high‐performance core‐shell photodetectors

Dual Side Chain Functionalization of Small Molecule Acceptors Affords High‐Performance Organic Solar Cells With Refined Blend Morphology

open access: yesAdvanced Functional Materials, EarlyView.
A new small‐molecule acceptor (SMA‐Ph‐CF3) is developed using a dual side chain functionalization strategy that incorporates trifluoromethyl and phenyl groups. This approach enables precise tuning of blend morphology, leading to the fabrication of high‐performance organic solar cells with a power conversion efficiency of 18.5%.

Eco‐Fabricated Nanowave‐Textured Implants Drive Microtubule‐Assisted Nuclear Mechanotransduction and Chromatin Modification: Biophysical Priming for Osteogenesis and Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
Eco‐friendly nanowave‐textured implants produced via femtosecond laser fabrication enhance bone regeneration by orchestrating a precise mechanotransduction cascade. This nanotopography directs mesenchymal stem cell alignment and cytoskeletal organization, triggering changes in nuclear shape and chromatin acetylation that prime cells for osteogenesis ...

Answering the age-old question: what does democracy mean to those who protest for it? [PDF]

open access: yes, 2017
There has long been a debate about democracy as a form of governance and whether it is in decline – Brexit and Trump have only exacerbated it. Drawing on research in four capital cities, Armine Ishkanian explains how activists view democracy.

Tuning the Hydrogen Bond Network Inside the Helmholtz Plane for Industrial Hydrogen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
The hydrogen bond network within the Helmholtz plane, a key component affecting the hydrogen evolution kinetics, remains far from having a consensus owing to the lack of fundamental understanding. Herein, it is discovered that the introduction of the atomic electric field generated by the weak Ru─Ga bonds can further improve the proportion of 4 ...
