In Situ Study of Resistive Switching in a Nitride‐Based Memristive Device
Advanced Functional Materials, EarlyView.In situ TEM biasing experiment demonstrates the volatile I‐V characteristic of MIM lamella device. In situ STEM‐EELS Ti L2/L3 ratio maps provide direct evidence of the oxygen vacancies migrations under positive/negative electrical bias, which is critical for revealing the RS mechanism for the MIM lamella device.

APPLICATION OF THE FACTORIAL EXPERIMENT IN THE QUALITY ANALYSIS OF THE MACHINED SURFACE OF AN ALUMINUM ALLOY RELATED TO THE VARIATION OF THE CUTTING PARAMETERS [PDF]
Annals: Series on engineering sciences (Academy of Romanian Scientists), 2020 In the cutting industry, surface finishing and product strength are essential in determining the quality. In this scientific research paper it is desired to analyze the way in which the influence of some cutting parameters that take different values, on

The geomorphological setting of some of Scotland's east coast freshwater mills: a comment on Downward and Skinner (2005) ‘Working rivers: the geomorphological legacy...’ [PDF]
, 2005 Many of the water mills on Scotland's east coast streams, unlike those discussed recently by Downward and Skinner (2005 Area 37 138–47), are found in predominantly bedrock reaches immediately downstream of knickpoints (i.e. bedrock steps).

Multiscale Structuring of Hydroxyapatite via Two‐Photon Lithography of Nanocomposites
Advanced Functional Materials, EarlyView.Hydroxyapatite scaffolds are of great interest in bone tissue engineering applications, ranging from 3D cell culture to regenerative medicine. Using two‐photon lithography of a transparent nanocomposite, hydroxyapatite microstructures with features ranging from submicron to centimeter‐scale are fabricated. This allows to mimic the natural bone geometry,
