The consolidation process of the EU regulatory framework on nanotechnologies: within and beyond the EU case-by-case approach [PDF]

open access: yes, 2015
The field of nanotechnologies has been the subject of a process of wide-ranging regulation, which covers two different trends. From the 2000s the European Commission and Parliament agreed on a type of adaptive, experimental and flexible approach, which ...

Self-assembly of 3D fennel-like Co3O4 with thirty-six surfaces for high performance supercapacitor [PDF]

open access: yes, 2017
Three-dimensional (3D) fennel-like cobalt oxide (II,III) (Co3O4) particles with thirty-six surfaces on nickel foams were prepared via a simple hydrothermal synthesis method and its growth process was also researched.

Non Thermal‐Driven Photocatalytic Ammonia Decomposition at Near‐Room Temperature on a Plasmonic Nanocone Array

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic photocatalytic ammonia decomposition occurs at near‐room temperature on a plasmonic Au nanocone array under visible light illumination. The nanostructure efficiently harnesses plasmonic modes, leading to increased reaction rates upon plasmon decay.

Selective directed self-assembly of coexisting morphologies using block copolymer blends

open access: yesNature Communications, 2016
There is a limited range of structures available in nanolithography using directed self-assembled block copolymers. Here, Black and co-workers expand directed self-assembly chemical patterning by using a blend of lamellar and cylinder forming block ...

Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors

open access: yesAdvanced Functional Materials, EarlyView.
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

Non-native three-dimensional block copolymer morphologies

open access: yesNature Communications, 2016
Molecules can self-assemble to form ordered phases with defined shape and periodicity, but there are a limited set of morphologies reported. Here, the authors have manipulated block copolymer thin films via an iterative assembly process to form a diverse
