Low-energy electron transmission imaging of clusters on free-standing graphene [PDF]

open access: yes, 2012
We investigated the utility of free-standing graphene as a transparent sample carrier for imaging nanometer-sized objects by means of low-energy electron holography.

Datasets: Sensitivity and protein digestion course of proteomic Filter Aided Sample Preparation

open access: yes, 2019
Sensitivity of FASP was tested using SDS lysates from HeLa cells and mouse brain. Peptides were analyzed using a QExactive HF-X instrument. Whole cell lysates of Hela cells were processed with FASP using single or double, consecutive or successive ...

Polarization fields in GaN/AlN nanowire heterostructures studied by Off axis holography [PDF]

open access: yes, 2013
In this work, we present an off-axis holography study of GaN/AlN heterostructured nanowires grown by plasma-assisted molecular-beam epitaxy. We discuss the sample preparation of nanowire samples for electron holography and combine potential profiles ...

Recent insights into xerogel and aerogel mineral composites for CO 2 mineral sequestration [PDF]

open access: yes, 2011
Supercritically dried composites have already been analysed and proposed as carbon dioxide sequesters. However, the economical and energetic costs of the supercritical drying process had to be re-evaluated, and were eventually found not to enhance the ...

Development and application of micromechanical techniques for characterising interfacial shear strength in fibre-thermoplastic composites [PDF]

open access: yes, 2012
The development of single fibre pull-out and microbond tests for characterising interfacial strength in thermoplastic composites is reviewed in detail. Manufacture of an experimental jig and sample preparation regimes for both tests are described.

Carbon nanotubes in high internal phase emulsion polymer composite for packed-cartridge micro-solid-phase extraction of fluoroquinolones in urine

open access: yesAdvances in Sample Preparation
Aim of this study stands in the evaluation of a carbon nanotubes-based polymerized high internal phase emulsion composite (CNT/polyHIPE) as sorptive phase in biological sample preparation. A micro-solid-phase extraction procedure (µSPE) was developed for

Sample Preparation — the First Step of Successful Research [PDF]

open access: yes, 2013
The overall goal of our research project is to study the unfrozen water mass and mobility in frozen soils. Frozen samples of standard clays with different adsorbed cations will be analyzed to determine their surface potential, micro-fabric, and how they ...

Size-independent Shear Band Formation in Amorphous Nanowires made from Simulated Casting

open access: yes, 2010
Molecular dynamics simulations indicate that surfaces strongly influence the strain localization behavior of amorphous nanowires in tension. A sample preparation routine that simulates casting was employed to facilitate the relaxation of the sample ...
