Sublimable materials facilitate the TEM sample preparation of oil-soluble nanomaterials

Applied Microscopy, 2020
Sample preparation is significantly important to the high-resolution transmission electron microscopy (HRTEM) characterization of nanomaterials. However, many general organic solvents can dissolve the necessary organic polymer support layer in TEM grid ...

Optical Characterization of ALD-Coated Nanoporous Alumina Structures: Effect of Sample Geometry or Coated Layer Material

Micromachines, 2023
Optical characterization of nanoporous alumina-based structures (NPA-bSs), obtained by ALD deposition of a thin conformal SiO2 layer on two alumina nanosupports with different geometrical parameters (pore size and interpore distance), was performed by ...

Internet of Samples (iSamples): Toward an interdisciplinary cyberinfrastructure for material samples [PDF]

GigaScience, 2021
Abstract Sampling the natural world and built environment underpins much of science, yet systems for managing material samples and associated (meta)data are fragmented across institutional catalogs, practices for identification, and discipline-specific (meta)data standards.

Aerosol filtration efficiency of household materials for homemade face masks: Influence of material properties, particle size, particle electrical charge, face velocity, and leaks

Aerosol Science and Technology, 2020
As a consequence of the COVID-19 pandemic caused by the SARS-CoV-2 virus, the widespread daily use of face masks is promoted worldwide. Particle-size dependent filtration efficiencies (FE; dp = 30 nm–10 µm), applying a particle counting approach, and ...

RANdom SAmple Consensus (RANSAC) algorithm for material-informatics: application to photovoltaic solar cells

Journal of Cheminformatics, 2017
An important aspect of chemoinformatics and material-informatics is the usage of machine learning algorithms to build Quantitative Structure Activity Relationship (QSAR) models. The RANdom SAmple Consensus (RANSAC) algorithm is a predictive modeling tool

Biodegradable carboxymethyl cellulose based material for sustainable packaging application

Scientific Reports, 2020
The main goal of the present work was to develop a value-added product of biodegradable material for sustainable packaging. The use of agriculture waste-derived carboxymethyl cellulose (CMC) mainly is to reduce the cost involved in the development of the

New double indentation technique for measurement of the elasticity modulus of thin objects [PDF]

, 2011
In this paper we introduce a new method to determine the Young's modulus of thin (biological) samples. The method is especially suitable for small objects with a thickness of a few hundred micrometers.

Interference of the Spectral Line Mζ in the M Energy Level Series of Ce on the F Element Kα Peak in Monazite Samples

Yankuang ceshi
Quantitative analysis of the ultra-light element fluorine (F) has always been one of the difficulties in electron probe microanalysis (EPMA). High-resolution qualitative analysis and proper subtraction of spectral interferences from major elements are ...
