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).

Toxicological and Environmental Safety Data - Case Study
IntroductionAGRAGEL is a cross-linked copolymer of acrylic acid and acrylamide partially neutralized as potassium/ ammonium salt. The polymer is in its dry form a granulate and forms a gel-like material upon addition of water or aqueous solutions. Due to the cross-linking it is insoluble in water. Uptake of water is facilitated mainly by the negative carboxylic groups of the polymer and their hydration with water molecules. Complete solubilization is hindered because of the cross-linking of different polymer...

An indigenous and industrially important manganese peroxidase (MnP) was isolated from solid-state bio-processing of wheat bran by white-rot fungal strain Ganoderma lucidum IBL-05 under pre-optimized growth conditions. Crude MnP extract was partially purified (2.34-fold) to apparent homogeneity by ammonium sulphate precipitation and dialysis. The homogeneous enzyme preparation was encapsulated on gelatin matrix using glutaraldehyde as a cross-linking agent. Optimal conditions for highest immobilization (82.5%)...
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...
