Editor’s note: This briefing was written by Admiral Instruments. Admiral Instruments will be exhibiting (booth 309) at the 233rd ECS Meeting in Seattle, WA this May. See a list of all our exhibitors.

You’ve probably heard your potentiostat ‘click’ while running a cyclic voltammetry experiment or similar sweep methods. Have you ever wondered where that clicking comes from, and why it happens?

The clicking sound is made by a series of electromechanical relays (AKA switches) when they turn on or off to direct the flow of current (I) to a different shunt resistor. A shunt resistor is a specialized resistor with high accuracy and a low temperature coefficient. In most commercially-available potentiostats, current is not directly measured. Rather, current readings are calculated by dividing the voltage drop (V) across the shunt resistor by the resistance (R) of the shunt resistor.

I = V/R


Advance Your Career

Professional Development WorkshopProfessional development workshops are a growing feature of the ECS biannual meetings. Several new and recurring workshops being held at the 233rd ECS Meeting in Seattle, WA. The workshops are led by industry and career professionals in order to best serve the interests for mid- and early-career researchers and students.

New workshop additions

An Introduction to Intellectual Property
Instructor: Matthew Rappaport, IP Checkups, Inc.

In recent years intellectual property has become contentious with notable high-tech companies influencing patent rights. Nevertheless, IP continues to play a key role in the development and innovation ecosystem, particularly for start-ups and early-stage commercialization. In this short course, we will get down to basics in exploring the role of IP in protecting your early-stage development and commercialization. Along the way, we will review IP basics and explore portfolio development to help protect your inventions. Decisions such as internal R&D, strategic partnerships or licensing are informed by your portfolio. And finally, what to do when you have to enforce your rights. This workshop is 2.5 hours.

Topic Close-up #11

Symposium E04: Electrodeposition of Reactive Metals and Alloys for Energy Storage

Symposium purpose is to bring together experts from the fields of electrodeposition and energy storage to discuss and learn about the science and technological issues in this fascinating topic which we share. Electrodeposition or plating of reactive compounds is common place in energy storage applications such as metal-air, lithium metal and next generation sodium, magnesium or calcium battery concepts. On the other hand, high quality coatings of reactive metals and alloys such as aluminum, magnesium, vanadium and zinc find applications in anti-corrosion coatings, microelectronics, fuel cells, electrolyzers, supercapacitors and sensors. We welcome all abstracts about novel deposition processes, electrolytes and additives, insights in kinetics, nucleation and growth phenomena, as well as on advanced applications in this field.

Confirmed Invited Speakers include Dr. Fanny Barde of Toyota Motor Europe, Dr. Debra R. Rolison of NRL, Prof. Craig B. Arnold from Princeton University, Prof. Takayuki Homma from Waseda University and Snehashis Choudhury, young investigator at Cornell University (group of prof. Lynden Archer).

Topic Close-up #10

Symposium G02: Atomic Layer Deposition Applications 14

Symposium Focus: This symposium focuses on a variety of applications of ALD and other atomic layer-by-layer processing in semiconductor CMOS (e.g. high-k oxides and metals for memories like Flash and 3D NAND, MIM, MIS capacitors), photovoltaics, energy storage and conversion, catalysis, optics and photonics, smart coatings of nanoporous materials, MLD and hybrid ALD/MLD, fundamentals of ALD processing: reaction mechanisms, in-situ measurement, modeling, theory, new precursors and delivery systems, optical and photonic applications, productivity enhancement, scale-up and commercialization of ALD equipment and processes for rigid and flexible substrates, including roll-to-roll deposition, spatial ALD, area-selective ALD, Atomic Layer Etching (‘reverse ALD’) and related topics aiming at self-limited etching.


Award winner DeijunThe winner of the 2018 Energy Technology Division Graduate Student Award sponsored by Bio-Logic is Deijun Xiong!

Each year, the ECS Energy Technology Division recognizes and rewards promising young engineers and scientists in fields pertaining to this division. The award was established in 2012 and is intended to encourage the recipients to initiate or continue careers in this field. ECS is proud to acknowledge Bio-Logic for its generous sponsorship of this award. Recipients receive a framed certificate, a $1,000 prize, complimentary student meeting registration and complimentary admission to the onsite division leadership meeting. The nomination deadline is September 1 of each year.

Deijun Xiong completed his PhD in chemistry at Dalhousie University in October 2017 under the supervision of Jeff Dahn.

During his PhD, he mainly focused on understanding the failure of high voltage LiNixMnyCo(1-x-y)O2 (NMC) cells and developing functional electrolyte for high voltage NMC cells. He put forward a novel “pouch bag” method to deepen understanding of the crosstalks occurring in Li-ion cells. He provided new support that oxygen can be released from charged polycrystalline NMC materials rather than single crystal NMC materials at mild temperature at high voltage. He also made contributions to develop ethylene carbonate-free electrolytes for high voltage NMC cells.
In December 2017, Deijun joined Shenzhen Capchem Technology Co. Ltd (one of the leading Li-ion battery and supercapacitor electrolyte companies in the world) as vice director of research and development to develop functional electrolytes for Li-ion battery and supercapacitor.

Spring 2018 division awards will be conferred at the 233rd ECS Meeting in Seattle, WA from May 13-17, 2018. Join Deijun as he delivers his award talk called “Understanding Crosstalks in Li-Ion Cells” on Wednesday, May 16 | 0820h in Room 608 of the Washington State Convention & Trade Center.

The 1st International Semiconductor Conference for Global Challenges (ISCGC 2017) was held in Nanjing, Jiangsu, China, July 16-19, 2017. The conference was jointly sponsored by The Electrochemical Society and the Chinese Physical Society.

The 200-plus attendees from around the world addressed the global challenges of semiconductor science and technology. The conference covered a wide spectrum of semiconductor research areas including growth and characterization, electronic/optoelectronic/power devices and their applications, and energy devices and systems.

On hand were eight keynote and 40 invited speakers. Thirty-seven contributing papers were presented, along with 66 posters. The meeting included 10 invited and keynote speakers from ECS as well as the involvement of five ECS divisions (Electronics and Photonics, Dielectric Science and Technology, Luminescence and Display Materials, Sensors, and Nanocarbons).

“ECS wants to have an influence in this region of the world as to the way scholarly publishing is carried out,” says Roque Calvo, executive director of ECS. “We want to communicate the idea of our Free the Science initiative — embracing open science to further advance research in our fields.”

ECS Teams Up With Tesla

On Saturday May 20, ECS participated in Pennington Day, a local community festival that highlights local artists, food and other vendors, and nonprofits. As one of the largest organizations in Pennington, NJ and with an important message to communicate, ECS took to the streets for the all-day street affair.

To engage passersby, we partnered with Tesla to demonstrate what our sciences look like when applied to the real world. The Tesla Model X, with its DeLorean-esque doors attracted plenty of curious people who inquired about the car’s capabilities. The top 3 questions were:

  • How far can you drive on one charge?
  • Where are there charging stations?
  • How much does it cost? The model we had was $110,000!

Pennington DayAnd for something for younger, budding scientists, we collaborated with students from PRISM (Princeton Institute for the Science and Technology of Materials) at Princeton University. They worked on building molecules out of gumdrops and toothpicks!

We had a steady stream of visitors, including some of our members, throughout the day and gave away prizes to people who could answer questions about our sciences. A big thanks to the organizers of Pennington Day and our partners at PRISM and Tesla for making our booth so successful at this event!
