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.

Microfluidic Extraction of Biomarkers Using Water as Solvent

Terahertz modulation of permittivity of water would enable solvation of molecules of interest. A proposed device, denoted a miniature microfluidic biomarker extractor (μ-EX), would extract trace amounts of chemicals of interest from samples, such as soils and rocks. Traditionally, such extractions are performed on a large scale with hazardous organic solvents; each solvent capable of dissolving only those molecules lying within narrow ranges of specific chemical and physical characteristics that notably include volatility, electric charge, and polarity. In contrast, in the μ-EX, extractions could be performed by use of small amounts (typically between 0.1 and 100 μL) of water as a universal solvent.
