Carbon nanotubes (CNTs), in particular the vertically-aligned variety grown through a PECVD-based process, are highly versatile nanostructures that can be used in a variety of nanomanufacturing applications. However, process and material compatibility issues have prevented the nanotubes from becoming more fully integrated into various micro- and nanomanufacturing applications. In this paper, we discuss the use of a folding titanium nitride membrane layer to more easily combine the nanotube growth process with other nanomanufacturing schemes, such as Nanostructured OrigamiTM (In et al., 2006).

Optimization of cyanide extraction from wastewater using emulsion liquid membrane system by ...
To solve the disposal problem of cyanide wastewater, removal of cyanide from wastewater using a water-in-oil emulsion type of emulsion liquid membrane (ELM) was studied in this work. Specifically, the effects of surfactant Span-80, carrier trioctylamine (TOA), stripping agent NaOH solution and the emulsion-to-external-phase-volume ratio on removal of cyanide were investigated. Removal of total cyanide was determined using the silver nitrate titration method. Regression analysis and optimization of the conditions...
Leader in sample preparation systems benefits from Axetris MFCs’ high dynamic range - Case Study
Split ratio flexibility of GC injector increased 30-fold A leading manufacturer of analytical sample preparation systems in gas chromatography (GC) switched to Axetris MFCs - and in doing so, simplified their product range, while offering their customers at least 30 times more flexibility in split ratio. The market-leading dynamic range of Axetris mass flow controllers (MFCs)—with their better than 1000:1 turn-down ratio—helped achieve this quantum leap forward in flexibility and performance. GC...
Influences of electroosmosis and electrophoresis on permeate flux and membrane fouling in submerged ...
The objective of this study was to investigate the influences of electroosmosis (EO) and electrophoresis (EP) on the permeate flux in submerged membrane bioreactors. When a polymeric membrane is placed in between an anode and a cathode, both EO and EP occur simultaneously, causing enhancement in flux. Results showed that after 150 min of filtration, the permeate fluxes were 60, 115, 175 and 260 L/m2/h at 0, 30, 40 and 50 V, respectively. It was shown that the EO was linearly changing with increasing voltage,...
High-throughput Microscale Bioanalysis is not a Paradox
Question: When someone says microscale chromatography, what comes to mind? Increased sensitivity? Reduced sample volume? Enhanced MS sampling efficiency? Yes, yes, and yes! You might also say, “finicky,” “slow,” or “only one person in our group knows how to use it!” Maybe even, “there’s no way I can successfully transfer that method, so why bother?” What if I said, “Reproducible, for routine throughput, and easy to use?” Believe it or not,...
