Amidinium salts: Towards enabling electrochemistry in non-polar media from alkanes to ionic liquids

open access: yesElectrochemistry Communications, 2017
Abstract There is little known about electrochemical behavior in non-polar media due to lack of compatible, hydrophobic salts. In this work, this difficult challenge has been overcome by following a strategy based on designing and synthesizing a novel family of organic salts with highly-delocalized cations and anions.

Photoelectrochemical ion concentration polarization : a microfluidic ion filtration system using light-driven electrochemical reactions [PDF]

open access: yes, 2019
We report an ion separation or filtration method used in microchannel called photoelectrochemical ion concentration polarization (pICP). As a variant of faradaic ion concentration polarization (fICP), pICP utilizes TiO₂ photoelectrochemistry to form an ...

Nanoscale Imaging of Lithium Ion Distribution During In Situ Operation of Battery Electrode and Electrolyte

open access: yes, 2013
A major challenge in the development of new battery materials is understanding their fundamental mechanisms of operation and degradation. Their microscopically inhomogeneous nature calls for characterization tools that provide operando and localized ...

Composition depth profile analysis of electrodeposited alloys and metal multilayers: the reverse approach [PDF]

open access: yes, 2011
The reverse depth profile analysis is a recently developed method for the study of a deposit composition profile in the near-substrate zone. The sample preparation technique enables one to separate the deposit and a thin cover layer from its substrate ...

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 ...

On the Investigation of a Sustainable Two Step Laser‐Based Surface Treatment for the Functionalization of Additive Manufactured Ti–6Al–4V Components

open access: yesAdvanced Engineering Materials, EarlyView.
This study developed a two‐step laser‐based process for sustainable surface treatment of Ti–6Al–4 V components, combining laser polishing and direct laser interference patterning with ns and ps pulses. Key findings include significant roughness reduction, hierarchical patterning with ps pulses, and improved homogeneity. A cost function is developed for
