Nanofiltration of Electrolyte Solutions by Sub-2nm Carbon Nanotube Membranes

Fornasiero F., Park H.G., Holt J.K., Stadermann M., Kim S., In J.B., Grigoropoulos C.P., Noy A., Bakajin O., Lawrence Livermore National Laboratory, US

Both MD simulations and experimental studies have shown that liquid and gas flow through carbon nanotubes with nanometer size diameter is exceptionally fast. For applications in separation technology, selectivity is required together with fast flow. [...]

Environmental and Economic Assessment of Nano-Fabrication Processes of Memory Devices

Dahlben L., Isaacs J.A., Northeastern University, US

The unique mechanical, electronic, and non-volatility of carbon nanotubes (CNT) have significant potential to replace current silicon-based switches. However, before fully integrating CNT switches into the semiconductor industry, the production costs and environmental impacts associated [...]

Sensor for real-time monitoring of food degradation

Ibrisimovic N., Bauer M., Pittner F., University Vienna, AT

The aim of our novel approach was to create a simple and cheap sensor providing reasonable sensitivity and selectivity to indicate the “best use before” period combined with a memory effect that cannot easily be [...]

A Portable Raman Sensor for the Rapid Identification of the Olive Oil

Qi X., Zhang X., Zou M., Chen Y., Ye J., Chinese Academy of Inspection and Quarantine, CN

The adulteration of the olive oil with lower-priced oils and its distinction of different classifications are serious problems in the olive oil market, a fast on-site screening method is needed to be developed. In addition [...]

Engineering of efficient biocatalysts using nanostructured mesoporous silicate carriers

Szymanska K., Bryjak J., Jarzebski A.B., Institute of Chemical Engineering, Polish Academy of Science, PL

Immobilization of free enzymes/proteins on water-insoluble mesoporous silica (MS) supports is often applied to obtain efficient biocatalysts for various applications. Three methods were applied for enzyme bonding onto MS: (1) physical adsorption with subsequent crosslinking [...]
