Battery Battle

A new type of redox flow battery from the Fraunhofer Institute for Chemical Technology (ICT) offers an advantage for electric cars. If the rechargeable batteries are low, the discharged electrolyte fluid can simply be exchanged at the gas station for recharged fluid – as easy as refilling the gas tank.

Could Small Springs Beat Batteries?

MIT scientists have found that carbon nanotubes could be formed into tiny springs capable of storing as much energy, pound for pound, as the best lithium-ion batteries - potentially more durably and reliably.

Algae Blooms Broaden Battery Possibilities

Blooms of Cladophora algae may be troublesome, but they do have a positive side. Researchers at the Ångström Laboratory of Sweden's Uppsala University have discovered that the cellulose nanostructure of these algae can serve as an effective coating substrate for use in environmentally friendly batteries.

Remote Diagnostic Technology for Hearing Assessment

Clinicians can remotely assess, diagnose, and remedy hearing loss. Individuals with hearing loss need to have ready access to hearing screenings, assessments, treatment, and consultation. This diagnostic technology facilitates early detection and intervention of hearing loss. It allows for improved monitoring and expands service scope, reach, and access. By reducing or eliminating travel times, it is also a more efficient utilization of time for audiologists and professional staff. The tele-hearing device and protocol provides clinicians the tools and the ability to remotely assess, diagnose, and remedy hearing loss. This is accomplished either directly or indirectly by facilitating assistance to other less experienced clinicians remotely.

Nano-Pervaporation Membrane With Heat Exchanger Generates Medical-Grade Water

A small system produces high-quality water using a heat exchanger that meets requirements for evaporation of substances such as pharmaceuticals and vitamins. A nanoporous membrane is used for the pervaporation process in which potable water is maintained, at atmospheric pressure, on the feed side of the membrane. The water enters the non- pervaporation (NPV) membrane device where it is separated into two streams — retentate water and permeated water. The permeated pure water is removed by applying low vapor pressure on the permeate side to create water vapor before condensation. This permeated water vapor is subsequently condensed by coming in contact with the cool surface of a heat exchanger with heat being recovered through transfer to the feed water stream.

Wireless Brain Implant Using a Telemetric Electrode Array System

A 3D intra-cortical electrode array is embedded for signal acquisition, processing, and wireless communication. The ability to monitor the activities of ensembles of single neurons is critically important in understanding the principles of information processing in the brain that underlie perception, cognition, and action. Multiple microelectrode recording using appropriate neuronal implants provides this ability. The Telemetric Electrode Array System (TEAS) project aims at developing and embedding a three-dimensional intra-cortical electrode array with all electronics required for signal acquisition, processing, and wireless communication entirely into the head.
