Smaller, More Powerful Li-Ion Battery

Researchers around the world are in a scientific race to develop a near-perfect lithium-ion battery, and a startup from the Massachusetts Institute of Technology (MIT) may have just unlocked the secret.

In 2012, Qichao Hu founded SolidEnergy – a startup that grew out of research and academics from MIT. Qichao started with battery technology that he and ECS member Donald Sadoway developed.

Now, the company is claiming to have built a lithium-ion battery that could change battery technology as we know it.

Beyond Open Access

"The unique and longer-term part of our OA plan is to "Free the Science™": to provide all ECS content at no cost to anyone—no fees for authors, readers, and libraries."

“The unique and longer-term part of our OA plan is to “Free the Science™“: to provide all ECS content at no cost to anyone—no fees for authors, readers, and libraries.”

Published in the latest issue of Interface.

The models of scientific communication and publication—which have served us all so well for so long—are no longer fully meeting the spirit of the ECS mission, may not be financially viable, and are hurting the dissemination of the results of scientific research.

The future of Open Access (OA) can change not only scholarly publishing, but can change the nature of scientific communication itself. OA has the power to more “evenly distribute” the advantages currently given to those who can easily access the outputs of scientific research.

ECS has long been concerned with facilitating that access, and our mission has been to disseminate the content from within our technical domain, as broadly as possible, and with as few barriers as possible. To accomplish this, we have maintained a robust, high-quality, high-impact publishing program for over 100 years.

Several years ago, ECS started taking a serious look at the challenges facing us in fulfilling our mission, specifically with respect to our publishing program. The challenges—faced by others in publishing, to a greater or lesser degree—are many and have become increasingly sever.

When a commercial scientific publisher is taking a 35% net profit out of the system, compared with under 2% by ECS, something is not only wrong, but it is clear that some publishers will do anything and everything they can to keep maintaining that level of profit. For many, journal publishing has indeed become a business.

The Real Science of an Alkali Metal Explosion

You may remember the classic alkali metal explosion demonstration in one of your early chemistry classes. Many educators use this experiment to show the volatile power of chemistry. The thought was that the unstable reaction was caused by the ignition of hydrogen gas, but scientists in the Czech Republic have found new information behind this classic demonstration by using high-speed video.

The researchers began investigating the science behind this experiment by dropping a sodium-potassium alloy droplet into water. From there, they recorded the explosion with a high-speed camera that is capable of capturing 10,000 frames per second.

Of course, there’s a video.

Modeling Corrosion, Atom by Atom

corrosion_atom_by_atomAn article by Christopher D. Taylor in the latest issue of Interface.

In the late 20th century, computer programs emerged that could solve the fundamental quantum mechanical equations that control the interactions of atoms that give rise to bonding. These tools, first applied to molecules and bulk solid materials, then began to be applied to surfaces and, in the early 21st century, to electrochemical environments. Commercial and open-source programs are now readily available and can be used on both desktop and high-performance computing platforms to solve for the electronic structure of a given configuration of atomic centers (nuclei) and, in so doing, provide the basis for determining a whole host of properties, including electronic and vibrational spectra, electrical moments such as the system dipole, and, most importantly, the energy and forces on the atoms. Other derived properties include the extent to which each atom is charged and bond-orders, although to compute these latter properties one of a variety of methods for dividing up and quantifying the electron density associated with each atom must be selected.

The physics behind these codes is complex, and, challengingly, has no rigorous analytical solution that can be obtained within a finite allotment of time. Thus, the computer programs themselves take advantage of approximations that allow for a feasible solution but, at the same time, constrain the accuracy of the result. Nonetheless, solutions can usually be reliably obtained for model systems representing materials, interfaces, or molecules that do not exceed thousands, and, more realistically, hundreds of atoms. Given that system sizes of hundreds or thousands of atoms amount to no more than the smallest nanoparticle of a substance, the question arises: What can atomistic simulations teach us about corrosion?

open_access“Comprehensive scientific assessments of our current and potential future climates clearly indicate that climate change is real, largely attributable to emissions from human activities, and potentially a very serious problem.” This is pulled from a public policy statement originally written in 2004 by the American Chemical Society.

Eighteen scientific societies signed on to a similar American Association for the Advancement of Science statement affirming the consensus scientific view on climate change in 2009. According to the California Governor’s Office of Planning and Research, at least 200 worldwide scientific organizations now formally hold the position that climate change has been caused by human action.

The International Panel on Climate Change (IPCC) was set up in 1988 to assess global warming and its impacts. Recently, the panel released a major report, capping its latest assessment, a mega-review of 30,000 climate change studies that establishes with 95-percent certainty that nearly all warming seen since the 1950s is due to human activity. More than 700 of the world’s top climate scientists and 1,729 expert reviewers from more than 70 countries participated in the report process.

You can’t unscramble an egg, but you can unboil one.

Chemists from the University of California, Irvine (UC Irvine) have found a way to unboil an egg by quickly restoring molecular proteins.

But this development is not as much about the egg as it is the process, which has the potential to slash biotechnology costs. The researchers believe this new process has the ability to dramatically reduce costs for cancer treatments, food production, and other segments of the $160 billion global biotechnology industry.

“Yes, we have invented a way to unboil a hen egg,” said Gregory Weiss, UCI professor of chemistry and molecular biology & biochemistry. “In our paper, we describe a device for pulling apart tangled proteins and allowing them to refold. We start with egg whites boiled for 20 minutes at 90 degrees Celsius and return a key protein in the egg to working order.”

The main purpose of the process is to quickly and efficiently produce or recycle valuable molecular proteins.

Everybody Writes, Nobody Reads

May it be then a reward to all the Interface authors to know that there is a crowd of people who read their work.

May it be then a reward to all the Interface authors to know that there is a crowd of people who read their work.

An article by Interface Co-Editor Petr Vanysek in the latest issue of the publication.

I am happy to report that people read Interface magazine. Just the other day I received a long letter commenting on the usefulness of the topical articles, this one specifically detailing the issue dealing with ionic liquids. The message of the letter was that the reviews in Interface are just as useful as the summary articles in peer-reviewed publications. Another reader, reacting to the side remark I made in my recent editorial about opening a dog kennel, wanted to unload his German shepherds on me. Yet another letter mentioned the Classics column and how nice it was to read recollections about scientists, written by other scientists and colleagues.

Interface does not have an officially gauged impact factor and we do not have a good measure of how well and thoroughly this magazine is read. Still, we like to hear that it is a useful medium for the members, the advertisers, and anybody else who may follow what shows up in our quarterly.

With climate change being a continually rising global dilemma, many scientist have turned their attention to research in the area of renewable energy sources. Even with some of the most brilliant minds working on improving efficiency and price of solar cells, they are still not widely used due to the high cost of materials used to develop the them. Now, a scientist may be on the path to cracking the code on material prices of solar cells by using nanotechnology.

Elijah Thimsen, assistant professor at the School of Engineering & Applied Science at Washington University in St. Louis, worked in conjunction with a team of engineers at the University of Minnesota to develop a technique to increase the performance of electrical conductivity.

Post Doc (NIR/EIS)
Irstea – Montpellier, France
This Post Doc is integrated to a binational project, NEXT. The goal of this project is to investigate the in-line and real-time use of novel holistic sludge descriptors to measure, monitor, model and predict sludge behaviour through sludge treatment processes and use this knowledge for the optimization of design and operation of treatment processes. It will lean on previous works developed by two Irstea teams (on the one hand on organic fluids characterisation based on electrical measurements and rheology and on the other hand on near infrared (NIR) spectroscopy on turbid fluids and soils).
