“Scientific discovery is a marathon, not a sprint. Sometimes you’re running faster or slower, but you always have to keep going.” Esther Takeuchi
Esther Takeuchi was the key contributor to the battery system that powers life-saving cardiac defibrillators.
She currently holds more than 150 U.S. patents, more than any other American woman, which earned her a spot in the Inventors Hall of Fame. Her innovative work in battery research also landed her the National Medal of Technology and Innovation in 2008.
“My nature is curiosity and The Electrochemical Society has gone a long way to satisfy my curiosity…” — A. Salkind
About two years ago, ECS began a conversation with Prof. Salkind about his proposal for a revised edition of Alkaline Storage Batteries. In the proposal we presented to John A. Wiley & Sons (our partner in publishing monographs), I said it was from “one of the ECS ‘giants’.”
That was quite true about Dr. Salkind. When I first met him (and ever after), I was engaged by his tremendous intellect, his wide-ranging curiosity, and his still being very much involved with his science.
Prof. Salkind was an emeritus member of ECS, having joined in 1952 as a student. He served the Society very well — as a Chair of our Battery Division and on an innovative committee called the New Technology Subcommittee. He became an ECS Fellow only in 2014, but over the course of his many years of involvement with ECS, he organized symposia, edited proceedings volumes, and chaired many committees.

In conjunction with developing a new edition of the Alkaline Storage Batteries book, Prof. Salkind began visiting ECS headquarters. We were immediately drawn in by his still-vibrant enthusiasm for the field and his fascinating anecdotes about other ECS notables in the field: Vladimir Bagotsky, Ernest Yeager, and Vittorio de Nora, among others. He was always willing to teach and to share. We were very fortunate to be able to “capture” Prof. Salkind in a very recent interview at the HQ office.
Professor Salkind generously considered ECS his technological home and brought his important monograph to be published by ECS. ECS is grateful to Dr. Salkind for his years of service to the Society and his contributions to the entire battery community; and we thank his family for supporting this remarkable person and sharing him with ECS.
Printing technologies in an atmospheric environment offer the potential for low-cost and materials-efficient alternatives for manufacturing electronics and energy devices such as luminescent displays, thin-film transistors, sensors, thin-film photovoltaics, fuel cells, capacitors, and batteries. Significant progress has been made in the area of printable functional organic and inorganic materials including conductors, semiconductors, and dielectric and luminescent materials.
These new printable functional materials have and will continue to enable exciting advances in printed electronics and energy devices. Some examples are printed amorphous oxide semiconductors, organic conductors and semiconductors, inorganic semiconductor nanomaterials, silicon, chalcogenide semiconductors, ceramics, metals, intercalation compounds, and carbon-based materials.
A special focus issue of the ECS Journal of Solid State Science and Technology was created about the publication of state-of-the-art efforts that address a variety of approaches to printable functional materials and device. This focus issue, consisting of a total of 15 papers, includes both invited and contributed papers reflecting recent achievements in printable functional materials and devices.
The topics of these papers span several key ECS technical areas, including batteries, sensors, fuel cells, carbon nanostructures and devices, electronic and photonic devices, and display materials, devices, and processing. The overall collection of this focus issue covers an impressive scope from fundamental science and engineering of printing process, ink chemistry and ink conversion processes, printed devices, and characterizations to the future outlook for printable functional materials and devices.

For printed electronic devices, metal thin film patterns with great conductivities are required. Three major ways to produce inkjet-printed metal tracks will be shown in this video.
What better day than Earth Day to highlight the work of ECS member Luke Haverhals, an assistant professor at Bradley University working in novel types of energy storage and conversion through the utilization of renewable, sustainable substrates such as hemp, wood, and silk.
Haverhals is a former student of current ECS 3rd Vice-President Johna Leddy. Since departing from Leddy and the University of Iowa, Haverhals has worked in an area focused on wielding natural fibers using ionic liquids (i.e. enhanced energy conversion devices).
Ionic liquids have been gaining much notoriety lately, with potential game changing electrolytes for energy conversion devices ranging from batteries to fuel cells.
Mary Yess, ECS Deputy Executive Director & Chief Content Officer, and Logan Streu, ECS Content Associate and Assistant to the CCO, recently came across a great video series that addresses a hot button topic here at ECS: access.
Through our mission to disseminate content to the largest possible audience with as few barriers as possible and our move towards full open access publication, ECS is working to help change the nature of scientific communication itself.
However, sometimes these technical research papers do not tell the important scientific stories that the everyday reader needs to know. For ECS, the Redcat blog was the answer to that issue. For Johns Hopkins University, their series “Science: Out of the Box” focuses on translating complex scientific concepts into understandable and entertaining stories.
A novel vibrating vest that will allow deaf people to feel sound is under development at Rice University. The low-cost, non-invasive VEST—Versatile Extra-Sensory Transducer—features dozens of embedded sensors to vibrate varying patterns based on the words spoken.
The VEST works in tandem with a phone or tablet app to isolate speech from ambient sound and allow for easier translation of the vibration patterns.
“We see other applications for what we’re calling tactile sensory substitution,” says Rice University junior Abhipray Sahoo. “Information can be sent through the human body. It’s not just an augmentative device for the deaf. The VEST could be a general neural input device. You could receive any form of information.”
Interested in how sensor technology could change the world? Make sure to join us at the 227th ECS Meeting in Chicago this May, where we’ll hold symposia dedicated to sensors and their applications in healthcare, the environment, and beyond.
Engineers have developed a way to visualize the optical properties of objects that are thousands of times small than a grain of sand. Source: YouTube/Stanford University
In order to develop high efficiency solar cells and LEDs, researchers need to see how light interacts with objects on the nanoscale. Unfortunately, light is tricky to visualize in relation to small-scale objects.
Engineers from Stanford University, in collaboration with FOM Institute AMOLF, have developed a next-gen optical method to produce high-resolution, 3D images of nanoscale objects. This allows researchers to visualize the optical properties of objects that are several thousandths the size of a grain of sand.
The teams achieved this by combining two technologies: cathodluminescence and tomography.

Researchers have been attempting to make a commercially viable aluminum-ion battery for years. Now, a team from Stanford University may have developed just the thing to outpace widely used lithium-ion and alkaline batteries.
The new aluminum-ion battery demonstrates high performance, a fast charging time, long-lasting cycles, and is of low cost to produce.
“We have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames,” said Hongjie Dai, a professor of chemistry at Stanford.
The researchers were able to achieve this novel battery by applying graphite as the cathode material.
His research activities include experimental investigations and mathematical modeling of localized corrosions, metal etching, high speed electrodeposition processes, porous electrodes, electro-organic synthesis, and plasma reactor design. Alkire received his M.S. and Ph.D. degrees in chemical engineering under ECS’s own Charles Tobias at the University of California Berkeley.
Take a moment to get to know him in this episode of ECS Talk.
