High Dielectric Breakdown Strength Nanoplatelet‐Based Multilayer Thin Films

open access: yesMacromolecular Materials and Engineering, 2023
Dielectric materials that can withstand high voltages are of great interest due to the growing need for high‐performance insulation systems in electronics. Polymer nanocomposites have gained popularity as electrical insulators due to their processability,

High performance free-standing films by layer-by-layer assembly of graphene flakes and ribbons with natural polymers [PDF]

open access: yes, 2016
In this work, novel free-standing (FS) films based on chitosan, alginate and graphene oxide (GO) were developed through layer-by-layer assembly. First, GO was synthesized from graphite and multi-walled carbon nanotubes using a modified Hummer's method ...

Strong bonds and far-from-equilibrium conditions minimize errors in lattice-gas growth [PDF]

open access: yes, 2017
We use computer simulation to study the layer-by-layer growth of particle structures in a lattice gas, taking the number of incorporated vacancies as a measure of the quality of the grown structure.

From bi-layer to tri-layer Fe nanoislands on Cu3Au(001)

open access: yes, 2001
Self assembly on suitably chosen substrates is a well exploited root to control the structure and morphology, hence magnetization, of metal films. In particular, the Cu3Au(001) surface has been recently singled out as a good template to grow high spin Fe

Comparative study of osteogenic activity of multilayers made of synthetic and biogenic polyelectrolytes [PDF]

open access: yes, 2017
Polyelectrolyte multilayer (PEM) coatings on biomaterials are applied to tailor adhesion, growth, and function of cells on biomedical implants. Here, biogenic and synthetic polyelectrolytes (PEL) are used for layer-by-layer assembly to study the ...

Preparation of lignosulfonate‐based nanofiltration membranes with improved water desalination performance

open access: yesEngineering in Life Sciences, 2021
Pulping and papermaking generate large amounts of waste in the form of lignosulfonates which have limited valorized applications so far. Herein, we report a novel lignosulfonate‐based nanofiltration membrane, prepared by using polyethylenimine (PEI) and ...

Selective targeting of proteins by hybrid polyoxometalates: Interaction between a bis-biotinylated hybrid conjugate and avidin [PDF]

open access: yes, 2018
The Keggin-type polyoxometalate [\u3b3-SiW10O36]8 12 was covalently modified to obtain a bis-biotinylated conjugate able to bind avidin. Spectroscopic studies such as UV-vis, fluorimetry, circular dichroism, coupled to surface plasmon resonance technique
