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.

The jet-propelled motors can swim though gastric acid by reducing hydrogen ions into hydrogen gas.

In a new study, researchers have developed a micromotor that can propel itself though the body to the stomach lining to deliver cargo.

While engineers have been developing micromotors for some time, it wasn’t until now that anyone has tested the device inside an animal. Researchers state that the results of this experiment show the potential of motorized particles to possibly improve the functions of nanoparticle drug carriers and imaging agents.

The micromotors were tested on mice to see the motor’s ability when delivering cargo to the stomach walls. Because the particles are jet-propelled, the researchers believed that they would be able to penetrate the layer of thick mucus that lines the stomach.

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.

New super-hydrophobic metals developed at the University of Rochester could mean big things for solar innovation and sanitation initiatives.

The researchers, led by Professor Chunlei Guo, have developed a technique that uses lasers to render materials extremely water repellant, thus resulting in rust-free metals.

Professor Guo’s research in novel not in the sense that he and his team are creating water resistant materials, instead they are creating a new way to develop these super-hydrophobic materials by taking away reliance on chemical coatings and shifting to laser technology.

You can thank “dendrites” when your smartphone battery goes from a solid 40 percent charge to completely dead in a matter of 20 minutes. Thankfully, researchers out of Purdue University are researching these dendrites – otherwise known as the slayer of lithium-ion batteries – and developing something that could greatly improve the li-ion.

Dendrites work to destroy lithium-ion batteries by forming an anode electrode and growing until they affect battery performance – potentially resulting in complete battery failure.

The new study out of Purdue University explores this issue with the intention of creating a safer and longer-lasting lithium-ion battery that could be charged within minutes instead of hours.

Along with a team of researchers out of Georgia Tech, ECS student member Alireza Mahdavifar has designed and fabricated the prototype of a microfluidic device that exploits cell movement to separate live and dead bacteria during food processing.

The research, entitled “A Nitrocellulose-Based Microfluidic Device for Generation of Concentration Gradients and Study of Bacterial Chemotaxis,” has been recently published in the Journal of The Electrochemical Society.

The new development consists of a microfluidic device that exploits cell movement to separate live and dead bacterial during food processing. The device is novel due to the fact that while screening for foodborne pathogens, it can be difficult to distinguish between viable and non-viable bacteria. Mahdavifar and the team out of Georgia Tech responded to this issue by creating a device that can separate live cells from dead ones for real-time pathogen detection.

Intel may be known for microprocessors and long-time ECS member Gordon E. Moore, but now the company’s Edison technology is lending itself to something entirely different.

They call it the Spider Dress, and the innovation involved in making this product goes far beyond sheer aesthetic value.

The 3-D printed dress was created by Anouk Wipprecht and uses Intel’s Edison technology to power robotic spider legs surrounding the collar, designed to keep people out of your personal space.

The dress’s robotic arms are connected to proximity sensors, which will react when someone gets too close to the wearer of the dress. Further, the sensors use biometric signals to measure the wearer’s stress level, which allow the dress to respond based on your mood.

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).
