Impact peak force measurement of potato [PDF]

open access: yesInternational Journal of Food Properties, 2020
To analyze the influencing factors of impact force on potatoes, a mathematical model between the impact peak force$${F_m}$$, the potato mass $$m$$ and the drop height $$h$$ was established as $${F_m} =km\sqrt h$$.

Peak forces and lateral resolution in amplitude modulation force microscopy in liquid [PDF]

open access: yesBeilstein Journal of Nanotechnology, 2013
The peak forces exerted on soft and rigid samples by a force microscope have been modeled by performing numerical simulations of the tip motion in liquid. The forces are obtained by using two contact mechanics models, Hertz and Tatara.

Nanofilaments on glioblastoma exosomes revealed by peak force microscopy. [PDF]

open access: yesJ R Soc Interface, 2014
Exosomes are sub-100 nm extracellular vesicles secreted by normal and cancer cells. We present a high-resolution structure of previously unidentified nanofilaments on glioblastoma-derived exosomes, using nanoscale peak force imaging. These stiff, adhesive, trypsin- and RNAse-resistant surface nanofilaments add a new dimension to the current structural ...

Peak Compression Force Physics in Rugby Union Scrum [PDF]

open access: yesProceedings, 2020
Scrums play a major role in Rugby Union games, and are historically known as a showdown between the two packs of opposing teams, composed of their eight forwards players organized in a 3-4-1 configuration, respectively.

Allometric equations for estimating peak uprooting force of riparian vegetation

open access: yesFrontiers in Plant Science, 2023
Uprooting caused by flood events is a significant disturbance factor that affects the establishment, growth, and mortality of riparian vegetation. If the hydraulic drag force acting on riparian plants exceeds the peak uprooting force originate from their

Liquid-Phase Peak Force Infrared Microscopy [PDF]

open access: yes, 2020
Atomic force microscopy-infrared microscopy (AFM-IR) provides a route to bypass Abbe’s diffraction limit through photothermal detections of infrared absorption. With the combination of total internal reflection, AFM-IR can operate in the aqueous phase. However, AFM-IR in contact mode suffers from surface damage from the lateral shear
