Atom-scale Manipulation Breakthrough

Bromine atoms

20 bromine atoms were positioned on a sodium chloride surface using the tip of an atomic force microscope at room temperature.

In the early days of this blog, Annie Goedkoop, Director of Publications for ECS, has been a great source for posts. Her latest from Engineering and Technology Magazine is about a discovery ECS member and past meeting attendee, Ernst Meyer, and his team are working on:

The first successful systematic atomic manipulation on an insulating surface at room temperatures has been achieved and presented by international researchers at the University of Basel, thereby taking the manipulation of atoms to a new level.

Pressure Sensors for Battery Packs

Below is a question raised in a discussion going on in our LinkedIn group. Consider joining.

I am looking for pressure sensor monitoring in a battery pack so that I can track the volume expansion of polymer or prismatic cells in a battery pack. Is anyone aware of any vendors that can provide samples of such sensors in consumer applications?

We have over 3,600 members in the group, ready to discuss.

If you have the answer to the above question, feel free to enter in the comments here. I’ll get it to the right place.

Latest Open Access Papers

ECS Digital Library

Easy-to-search, high-tech platform ensuring a progressive atmosphere for the exchange of knowledge and ideas.

As of today, 205 Open Access papers have been submitted to ECS journals of which 87 were published to the ECS Digital Library. Here are the three latest:

Where Do Good Ideas Come From?

NPR Ted Radio Hour

NPR take several talks that fit into the episode’s theme, replay parts of them, and often interview the speakers to get more insight.

The Ted Radio Hour is an NPR show that features TedTalks (shame on you if you have never listened). NPR take several talks that fit into the episode’s theme, replay parts of them, and often interview the speakers to get more insight.

A recent episode caught my ear —What is Original?

When is copying flattery, when is it thievery, and when is it sheer genius? In this hour, TED speakers explore how sampling, borrowing, and riffing make all of us innovators.

In particular was the section with writer Steven Johnson’s TedTalk — Where Do Good Ideas Come From?

Earlier this year, Tesla Motors CEO Elon Musk decided to give away his company’s patents for free. It might seem like a strange business move, but Musk said he wanted to inspire creativity and accelerate innovation. Writer Steven Johnson says this is the way great ideas have been born throughout history.

ECS blogger Dan Fatton commended Tesla recently. Turns out people are seeing that Open Access, a concept ECS is dedicated to, is where good ideas come from.

Have You Seen Reddit?

Reddit Science Logo

What are people talking about?

Here’s something you might not have considered — Reddit. It calls itself a “platform for internet communities where your votes shape what the world is talking about.” There are a range of topics on Reddit, some not for the faint of heart. But you can find some science sub-Reddits. Here’s the general science one to get you started. It has close to 6 million subscribers. That’s a lot of power.

You also might be interested in the AMAs (Ask Me Anything) in the right column. They’re Q&As with scientists.

It’s just for fun, but be warned, it can be a deep rabbit hole once you start.

Atomic Layer Etching and Cleaning

Here’s our latest Call for Papers:

Atomic Layer Etch (ALEt) and Atomic Layer Clean (ALC) are emerging as enabling technologies for sub 10nm technology nodes. At these scales performance will be extremely sensitive to process variation.

Atomic layer processes are the most promising path to deliver the precision needed. However, many areas of ALEt and ALC are in need of improved fundamental understanding and process development. This focus issue will cover state-of-the-art efforts that address a variety of approaches to ALE and ALC.

Topics of interest include but are not limited to:

  • Surface reaction chemistry and its impact on selectivity
  • Plasma ion energy distribution and control methods
  • Novel plasma sources and potential application to ALEt & ALC
  • Innovative approaches to atomic layer material removal
  • Novel device applications of ALEt & ALC
  • Process chamber design considerations
  • Advanced delivery of chemicals to processing chambers
  • Metrology and control of ALEt & ALC
  • Device performance impact
  • Synthesis of new chemistries for ALEt & ALC application
  • Damage free surface defect removal
  • Process and discharge modeling

What is clear is that an important part of the future is the increasing adoption of Open Access.

This piece, by ECS Executive Director, Roque Calvo, appeared in Interface, Spring 2014 issue. This is the heart of where we are headed as an organization. (The new Interface is out soon. Watch your mailboxes. Find out how to subscribe to our journals.)

Since the dawn of modern science, the key to scientific advancement has been the exchange of knowledge in publications, meetings, and through other collaborations; and in the past decade we have experienced a significant change in the way this scientific exchange occurs. Digital information and the Internet have dramatically improved our ability to disseminate science on a worldwide scale and should lead to global advances at a pace never considered before. But there are obstacles because these technological advancements in the digital age have come at a high cost to scholarly publishing; not for producing scientific content but for the cost of dissemination incurred by users of the research and their institutions.

Sand-base lithium ion batteries

Researchers have developed a lithium ion battery made of sand that outperforms the current standard by three times. Credit: UC Riverside.

Annie Goedkoop, Director of Publications for ECS ran across this story in Phys.org.

Researchers at the University of California, Riverside’s Bourns College of Engineering have created a lithium ion battery that outperforms the current industry standard by three times. The key material: sand. Yes, sand.

“This is the holy grail – a low cost, non-toxic, environmentally friendly way to produce high performance lithium ion battery anodes,” said Zachary Favors, a graduate student working with Cengiz and Mihri Ozkan, both engineering professors at UC Riverside.

Dye-sensitized socal cell

From: Perovskite Solar Cells: Rising, Last Advances, and Future Perspectives

This post went up the other day in our ECS Linkedin group:

Perovskite Solar Cells: Rising, Last Advances, and Future Perspectives

The progress made by emerging photovoltaic technologies in the last year has been outstanding. Important steps towards the realization of silicon-free solid-state solar cells with a real potential for commercialization were taken. In particular, a number of milestones have been achieved in the development of hybrid mesoscopic and thin-film solar cells based on the use of nanocrystals of organometal halide perovskites as the light absorbers. Under this approach, the power conversion efficiency (PCE) has been boosted from values around 6-8% (hold by metal chalcogenide solar cells) to over the 19%. Such a performance is now very close to the 25% of crystalline silicon solar cells, the leading commercial technology. But the most intriguing is that these breakthroughs have been achieved in devices entirely fabricated in the solid state, which, so far, had shown worse energy conversion abilities than their counterparts based on liquid electrolytes like dye-sensitized solar cells.  Read the rest.

Peer Review and Citation Ring

Journal of Vibration cover

SAGE Publications retracts 60 papers.

Peer review of our journals is one of the things we are most proud of here at The Electrochemical Society. Even as we move to Open Access for our publications, our peer review process is going to remain as rigorous as ever. Amazing the lengths people will go to beat the system though. This from RetractionWatch.com:

SAGE Publishers is retracting 60 articles from the Journal of Vibration and Control after an investigation revealed a “peer review and citation ring” involving a professor in Taiwan.

Here’s another piece I found interesting background reading, it’s about a year old, about how easy it is to get fake papers published because of the lack of good peer review.

PS: If you want to publish in a nice, no drama atmosphere, think of ECS.
