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 ...

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 ...

Fe thermomechanics and material sampling points [PDF]

Computer Methods in Applied Mechanics and Engineering, 1987
The thermomechanics of finite elements of continuous media is discussed. The novel key concept introduced is that of material sampling points attributed to each finite element. Similar to representing the spatial interactions by a finite number of nodal quantities, the state of a finite element is represented by the set of local states at its sampling ...
