Regio-selective substitution at the 1,3- and 6,8-positions of pyrene for the construction of small dipolar molecules [PDF]

open access: yes, 2015
© 2015 American Chemical Society. This article presents a novel asymmetrical functionalization strategy for the construction of dipolar molecules via efficient regioselective functionalization along the Z-axis of pyrene at both the 1,3- and 6,8-positions.

Linking Heat Treatment to Plastic Deformation in Pearlitic Steels Through Mesoscale Modeling

open access: yesAdvanced Engineering Materials, EarlyView.
Surface wear on rail and wheel steels results from surface deformation during use. This research uses mathematical models to forecast the plastic behavior of pearlitic steels, connected to the microstructure formed during heat treatment. While the cooling rate impacts the steels’ strength, the size of prior austenite grains and blocks does not ...

Improved Strength and Corrosion Resistance of Ti–50Zr Alloy Through Heat Treatment

open access: yesAdvanced Engineering Materials, EarlyView.
This work systematically analyzes the effects of heat treatment on mechanical properties and corrosion behavior of Ti‐50Zr alloy produced via vacuum arc melting. Microstructure transforms from coarse lamellar α phase in as‐cast condition to fine and uniformly distributes acicular α′ phase in heat‐treatment state.

Electrochemical Impedance Imaging via the Distribution of Diffusion Times [PDF]

open access: yes, 2017
We develop a mathematical framework to analyze electrochemical impedance spectra in terms of a distribution of diffusion times (DDT) for a parallel array of random finite-length Warburg (diffusion) or Gerischer (reaction-diffusion) circuit elements.
