Faraday Cage - How does it work

What is a Faraday Cage? How does it work?

Michael Faraday’s studies and experiments regarding charge, magnetism found that charge on a conductor resided only on the outer surface. He also discovered that nothing inside that conductor was affected by any change in electrical charge on the outside. Faraday believed that an electric field extended into space beyond a charge. We now know that Read more about What is a Faraday Cage? How does it work?[…]

Gamry Reference 600+ Potentiostat

Understanding Potentiostat Specs

The various parameters that are typically listed in the specifications of potentiostats are explained in this Technical Note originally posted by Gamry Instruments. There are many important factors that pertain to buying a potentiostat,  and the old adage “The more the better” really does not apply when researching the potentiostat to fit your experiment. There Read more about Understanding Potentiostat Specs[…]

Flexible Lithium-Ion Batteries

A solid, printable electrolyte enables lithium-ion batteries to take many shapes Engineers dreaming up new pacemakers, watches, or whatever wearable gadgets come after Google Glass have to tailor their designs around existing battery shapes—typically cylinders, pouches, or rectangles. But a team of researchers hopes their fully printable, flexible lithium-ion batteries will one day free designers Read more about Flexible Lithium-Ion Batteries[…]

Electrochemical Exfoliation of Graphene

Graphene Electrochem Exfoliation

“Whilst electrochemistry has been around for a long time it is a powerful tool for nanotechnology because it’s so finely tuneable” A simple electrochemical method has been used to tune the electrical and mechanical properties of graphene. AsianScientist (Aug. 11, 2015) – Graphene has been called the miracle material but the single-atomic layer material is Read more about Graphene Electrochem Exfoliation[…]

electrochemistry in an autoclave

Electrochemistry in an Autoclave

Contributed by Dr. Jim Hardy

Introduction

Acknowledgments

When I sit down to write about tricks of the trade and lessons learned in the practice of performing electrochemistry in autoclaves, my first thought is of all of those who preceded me in the adventure. This is only a partial and personal list: They are the researchers, facility engineers, supervisors, and technicians at Bettis and Knolls who paved the way. Some names that come to mind are Rick Garstka, Ted Druga, Bert Setterberg, Rudy Majcher, Jack Carr, Bob Rubino, Doug Thompson, Ken Granger, Rosemary Janik, Bill Archer, Garry Lynch, Irene Rosati, Mike Ochap, Dave Kedzierski, Keith Eklund, George Halbfinger, Mike Danielson, Yinfang Wang. Chief among those in other organizations who shared their stories was Digby Macdonald, who broke ground for many of us and was always eager to share his experiences.

Scope and Intent

This note will cover many topics that have only hot water in common. To fit within the space limitations of an application note, it will be a collection of lessons learned. As such, none of this is purely my own. There will be a stream of consciousness or memory and no part will be comprehensive. There may be future, detailed application notes to cover particular situations in depth, but they will await the questions that we hope this note will stimulate.
