Fluctuations of Dry and Total Mass of Cells Exposed to Different Molecular Weights of Polyethylene Glycol

Advanced NanoBiomed Research, 2023
Polyethylene glycol (PEG) is used in many applications, and in the clinical field, it is one of the main components of the latest Covid vaccines. Its wide use is justified by a relatively safe profile and few known side effects.

Nano and Micro indentation studies of bulk zirconia and EB PVD TBCs [PDF]

, 2004
In order to model the erosion of a material it is necessary to know the material properties of both the impacting particles as well as the target. In the case of electron beam (EB) physical vapour deposited(PVD) thermal barrier coatings (TBCs) the ...

Predicting the Mechanical Behaviour of Starch Gels through Inverse Analysis of Indentation Data

Applied Rheology, 2010
Two types of starch gels made with various starch/water concentrations were studied in terms of their mechanical behaviour. Indentation tests were performed which revealed a rate independent load-deflection response.

Experimental Analysis of Transseptal Puncture to Investigate the Mechanical Properties of Fossa Ovalis

Applied Sciences, 2023
Background/Objective: Optimization of needle characteristics for trans-septal puncture is of paramount importance to reduce the extent of tissue deformation. This was achieved by studying the mechanical behavior of fossa ovalis (FO) in lamb hearts.

On the Evolution of Nano-Structures at the Al–Cu Interface and the Influence of Annealing Temperature on the Interfacial Strength

Nanomaterials, 2022
Molecular dynamics (MD) simulations are invoked to simulate the diffusion process and microstructural evolution at the solid–liquid, cast-rolled Al–Cu interfaces. K-Means clustering algorithm is used to identify the formation and composition of two types

Role of indentation depth and contact area on human perception of softness for haptic interfaces

Science Advances, 2019
This work provides a model for designing materials that humans perceive as soft based on material and geometric properties. In engineering, the “softness” of an object, as measured by an indenter, manifests as two measurable parameters: (i) indentation ...
