The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

Advanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Study on Effect of Nickel Transition Layer on Microstructure and Thermal Stability of Anti-volatilization Tungsten Coating

Yuanzineng kexue jishu
To address material failure of key components in space nuclear reactors under high-temperature and ultra-high vacuum conditions and enhance their ability to withstand severe accidents, it is necessary to develop anti-volatilization coatings with ...

Cobalt Recovery by the Chlorination-Volatilization Method

, 2019
This communication presented the chlorination-volatilization of cobalt using calcium chloride. Effects of variables on the cobalt volatilization rate were investigated, including the flow rate, oxygen partial pressure, and water vapor content of the ...

Digital Light Processing of Thermoplastic Poly(methyl methacrylate) Photoresin Combined With Solvent Vapor Smoothing

Advanced Engineering Materials, EarlyView.
A thermoplastic PMMA‐based photoresin enables high‐resolution DLP printing followed by solvent‐vapor smoothing. The treatment reduces staircase‐induced surface roughness from 2.33 µm to 129 nm and increases visible‐light transmittance from approximately 30% to 80%, providing a route toward transparent PMMA components for rapid prototyping and non ...

Volatility and arbitrage [PDF]

The Annals of Applied Probability, 2018
The capitalization-weighted total relative variation $\sum_{i=1}^d \int_0^\cdot μ_i (t) \mathrm{d} \langle \log μ_i \rangle (t)$ in an equity market consisting of a fixed number $d$ of assets with capitalization weights $μ_i (\cdot)$ is an observable and nondecreasing function of time.

Influence of Particle Shape and Size in Copper‐Based Low‐Temperature Metallization Paste for Solar Cells

Advanced Engineering Materials, EarlyView.
Particle morphology controls the balance between printability and electrical connectivity in low‐temperature AgCu/Ag metallization pastes. Flake‐shaped AgCu particles form extended low‐resistance contacts, whereas spherical particles favor processability at high metal loading. Fine Ag particles further tune void filling and conductive‐network formation

Stochastic Volatility of Volatility in Continuous Time

, 2009
This paper introduces the concept of stochastic volatility of volatility in continuous time and, hence, extends standard stochastic volatility (SV) models to allow for an additional source of randomness associated with greater variability in the data.

Verification of wind-driven volatilization models

, 2006
Mass-transfer processes of paramount importance, such as reaeration and volatilization, occur at the air-water interface. Particularly, volatilization is intensively studied because it can be a relevant removal process for toxic contaminants from flowing
