Experimental investigation on the effet of input paramètres on surface roughness and MRR of abrasive flow machining process [PDF]

open access: yesE3S Web of Conferences, 2023
A crucial and costly step in the whole manufacturing process is the precision and super finishing procedure. A step of final finishing is involved in the production of precision components.

AFM imaging of functionalized carbon nanotubes on biological membranes [PDF]

open access: yes, 2009
Multifunctional carbon nanotubes are promising for biomedical applications as their nano-size, together with their physical stability, gives access into the cell and various cellular compartments including the nucleus.

Induced pluripotent stem cells-derived neurons from patients with Friedreich ataxia exhibit differential sensitivity to resveratrol and nicotinamide

open access: yesScientific Reports, 2019
Translation of pharmacological results from in vitro cell testing to clinical trials is challenging. One of the causes that may underlie these discrepant results is the lack of the phenotypic or species-specific relevance of the tested cells; today, this

Functional analysis of biological matter across dimensions by atomic force microscopy (AFM): from tissues to molecules and, ultimately, atoms [PDF]

open access: yes, 2004
For a detailed understanding of biological tissues and proteins and their dynamical processes the 3D structures of the components involved must be known.

Quantitative investigation of calcimimetic R568 on beta cell adhesion and mechanics using AFM single-cell force spectroscopy [PDF]

open access: yes, 2014
In this study we use a novel approach to quantitatively investigate mechanical and interfacial properties of clonal β-cells using AFM-Single Cell Force Spectroscopy (SCFS). MIN6 cells were incubated for 48hrs with 0.5mM Ca2+ ± the calcimimetic R568 (1μM).

Receptor trafficking and AFM [PDF]

open access: yesPflügers Archiv - European Journal of Physiology, 2007
Adaptation of a cell behavior to the environment is possible due to the biochemical and physical information that is transmitted through molecular receptor present at the cell surface. Regulation of receptor distribution and trafficking is thus a key feature to allow cells to properly respond to extracellular signals.

AFM-IR: Technology and Applications in Nanoscale Infrared Spectroscopy and Chemical Imaging [PDF]

open access: yes, 2016
Atomic force microscopy-based infrared spectroscopy (AFM-IR) is a rapidly emerging technique that provides chemical analysis and compositional mapping with spatial resolution far below conventional optical diffraction limits.

Improvement of the Properties of Ti6Al7Nb Titanium Alloy in Terms of the Type of Surface Modification [PDF]

open access: yesArchives of Metallurgy and Materials, 2020
The paper presents the influence of ZrO2 coating on Ti6Al7Nb titanium alloy depending on the method of deposition. The coatings were made by sol-gel method and atomic layer deposition (ALD).
