Pseudo force acting between bodies

open access: yesResults in Physics, 2016
It has been shown that a non-contact force acts between two macroscopic physical objects held close together, which is not associated with the gravitational and electrostatic force. An experiment was conducted with objects of different mass, material and

An Explicit Constitutive Reconstruction Framework for Mechanical Characterization of Miniaturized 3D‐Printed Specimens

open access: yesAdvanced Engineering Materials, EarlyView.
An explicit constitutive reconstruction framework enables accurate tensile characterization of miniaturized additively manufactured specimens using only the grip‐to‐grip displacement measurements. Progressive validation through self‐consistency, analytical comparison, and inverse finite element method (iFEM) benchmarking demonstrates constitutive ...

Correlative force and tip-enhanced Raman microscopy

open access: yesAPL Photonics, 2019
Tip-enhanced Raman scattering (TERS) microscopy attracts increasing attention for visualization and characterization of strain distribution on crystalline samples at a nanoscale due to nano-sized fields localized at a metal tip. However, as the metal tip

The Attract Force Equation of Energy [PDF]

open access: yesAmerican Journal of Modern Physics, 2014
The attract force equation of energy deduced from the Newton the principle of gravitation and the mass–energy equation (E=mc2) of Einstein. The equation describe the attract force cause by two energy fields. It can be said that the energy exists in any form (such as energy of heat, energy of photon, electronic energy, magnetic energy, even kinetic ...

Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring

open access: yesAdvanced Engineering Materials, EarlyView.
Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which

Suitable Method for Improving Friction Performance of Magnetic Wheels with Metal Yokes

open access: yesRobotics
A magnetic-wheeled robot is a type of robot that inspects large steel structures instead of humans, and it can run on a three-dimensional path by using wheels with built-in permanent magnets.
