Tribology of ZrC Coatings and Spherical Tips Acquired with Extraordinarily Stiff, Metal Atomic Force Microscopy Probes

open access: yesAdvanced Engineering Materials, EarlyView.
In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...

Randomness in Classical Mechanics and Quantum Mechanics [PDF]

open access: yesFoundations of Physics, 2010
The Copenhagen interpretation of quantum mechanics assumes the existence of the classical deterministic Newtonian world. We argue that in fact the Newton determinism in classical world does not hold and in classical mechanics there is fundamental and irreducible randomness.

From Nature to Engineering: Mortar Volume and Interfacial Mechanics in Bioinspired Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Inspired by natural armors like nacre, this study explores how varying the volume fraction of the soft mortar layer impacts the interfacial strength and toughness of bioinspired ceramics. Experimental and computational analysis reveals that higher mortar volumes increase energy dissipation but reduce interfacial stiffness, offering insights for ...

Comparação entre a mecânica relativista e a mecânica newtoniana

open access: yesRevista Brasileira de Ensino de Física
Comparação entre as mecânicas Relativista e Newtoniana é realizada num dado sistema de coordenadas, sem nenhuma preocupação com eventuais outros sistemas de coordenadas inerciais em movimento relativo, o que permite percepção mais direta das diferenças ...

First‐Principles Modeling of Solid Solution Softening and Hardening Effects in Al–Mg–Zr–Si Aluminum Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
The role of various alloying elements in face‐centered cubic aluminum on the barrier of a Shockley partial dislocation during its motion is presented. The study aims to understand how alloying atoms such as Mg, Si, and Zr affect the energy landscape for dislocation motion, thus influencing the solid solution hardening and softening in aluminum, which ...

Superposition and second quantization in classical mechanics

open access: yesResults in Physics, 2019
Some natural phenomena can be measured directly, while others are recognized indirectly by clues. In this study, we show that the classical laws of mechanics can be reformulated with entangled labeling-states that experience a collapse.

Causal Classical Physics in Time Symmetric Quantum Mechanics

open access: yesProceedings, 2017
The letter submitted is an executive summary of our previous paper. To solve the Einstein Podolsky Rosen “paradox” the two boundary quantum mechanics is taken as self consistent interpretation of quantum dynamics.
