Direct hydrothermal synthesis of LiMn2O4 spinel and lithium ion selective adsorption

Zhang Q-H, Sun S-Y, Li S-P, Yin X-S, Yu J-G, East China University of Science and Technology, CN

Spinel LiMn2O4, in which the [Mn2O4] framework provides a three-dimensional interstitial space for Li+ transportation, shows excellent Li+ insertion and extrusion property from the Mn-O lattice. The lithium ion-sieve effect strongly depends on the crystal [...]

Water Purification Using Carbon Nanotubes

Cummings A., Seldon Technologies, Inc., US

As we learn more about the hundreds of contaminants common in water, the decline of our water infrastructure, and the potentially harmful effects of chemical treatments, it is not surprising that consumers are turning to [...]

Lombardo P., Lombardo Associates, Inc., US

The Malibu Creek Plaza is a shopping plaza consisting of both retail and commercial businesses, located in an environmentally sensitive area adjacent to the famous Surfrider Beach in Malibu, California. In 1999 the California Regional [...]

Drinking water treatment with Caspian region natural sorbents

Egorov M.A., Astrakhan State University, RU

The present work is focused on developing effective and efficient mass consumer household filters to treat drinking water with natural sorbents which is especially important for developing regions communities. The aim of the research was [...]

Off-Grid Fuel Cell System for High Power Quality Applications

Lima R.J.S., de Almeida A.T., Mendes A.M.S., Mendes A.M.S., Cardoso A.J.M., University of Coimbra, PT

There is a variety of critical loads, such as information technology, telecommunication, medical equipment and industrial process controls, which require high power quality. Conventional approaches to provide high power quality levels include battery based uninterruptible [...]

Improving Water Management in Fuel Cell Flow Channels via Oscillation of Water Droplets

Schultz R., Diebel J., Allen J., Michigan Technological University, US

To achieve maximum efficiency and reliability in a PEM fuel cell, a balance between keeping the membrane from becoming too dry or too wet must be monitored carefully. At present, product water is moved through [...]

Structured carbon nanotubes for hydrogen storage for on-board vehicle application with 6.5 wt %

Uchrin J., Uchrin R., Uchrin J., Uchrin R., Hydrogen Related Materials LLC, US

The main objective is achieving and exceeding the benchmark of 6.5% H2 to system weight ratio set by the Department of Energy. The reported gravimetric storage of H2 in various carbon materials shows quite large [...]

Meka D., Onbattuvelli V., Atre S., Prasad S., Portland State University, US

We present here the design , fabrication and development of a minaturized electrical sensor for aggresive environment monitoring of energy systems.

Towards In-Situ Reservoir Nano-Agents

Kanj M.Y., Funk J.J., Saudi Aramco, SA

The advent of atomically accurate sensing and manipulation tools has spurred a widespread interest in nanotechnology with the prospect of re-engineering matter and synthesizing functional systems at the nanoscale. This enabled thinking “outside-the-box” in valuable [...]

Electrospun Nanofiber Layers for Applications in Electrochemical Devices

Rubáek L., Duchoslav J., Zukalová M., Procházka J., Kavan L., Elmarco Ltd., CZ

Low power and/or low energy density belong to main limiting parameters of electrochemical energy storage devices. Increasing of the surface area between an electrolyte and an active electrode material is the way how to improve [...]
