Influence of clamp-widening on the quality factor of nanomechanical silicon nitride resonators

, 2019
Nanomechanical resonators based on strained silicon nitride (Si$_3$N$_4$) have received a large amount of attention in fields such as sensing and quantum optomechanics due to their exceptionally high quality factors ($Q$s).

Probing nanomechanical properties from biomolecules to living cells [PDF]

Pflügers Archiv - European Journal of Physiology, 2008
Atomic force microscopy is being increasingly used to explore the physical properties of biological structures. This technique involves the application of a force to the sample and a monitoring of the ensuing deformation process. The available experimental setups can be broadly divided into two categories, one of which involves a stretching and the ...

Nano Hydroxyapatite-coated Implants Improve Bone Nanomechanical Properties [PDF]

Journal of Dental Research, 2012
Nanostructure modification of dental implants has long been sought as a means to improve osseointegration through enhanced biomimicry of host structures. Several methods have been proposed and demonstrated for creating nanotopographic features; here we describe a nanoscale hydroxyapatite (HA)-coated implant surface and hypothesize that it will hasten ...

Artificial weathering aging of PPT coatings made from recycled PET to protect concrete: Nanomechanical properties evaluation

Journal of Materials Research and Technology
The objective of this work was to artificial weathering age polypropylene terephthalate (PPT) coatings obtained from polyethylene terephthalate (PET) recycled for the evaluation of their nanomechanical properties, which are proposed for the protection of

Generalized Hertz model for bimodal nanomechanical mapping

Beilstein Journal of Nanotechnology, 2016
Bimodal atomic force microscopy uses a cantilever that is simultaneously driven at two of its eigenmodes (resonant modes). Parameters associated with both resonances can be measured and used to extract quantitative nanomechanical information about the ...

Nano-mechanical properties of diabetic glycogen

Carbohydrate Polymer Technologies and Applications
Glycogen, a highly branched glucose polymer, plays a vital role in maintaining blood sugar homeostasis in vivo. Liver glycogen molecules contain small “β particles” bound together into larger composite “α particles”.

Nanomechanical Properties of Supported Lipid Bialyers [PDF]

Biophysical Journal, 2011
Lipid reorganization induced morphology alteration in asymmetric bilayers prepared by Langmuir-Blodgett (LB)/ Langmuir-Schaeffer (LS) method was directly visualized by means of the atomic force microscopy (AFM) and fluorescence imaging. The LB monolayer in the bilayer system was prepared using binary mixture of 1,2-dioleoyl-sn-glycero-3-phosphocholine (
