Inkjet Printing of 2d Materials on Flexible and Rigid Substrates
… phase exfoliation (UALPE) of bulk graphite in isopropyl alcohol (IPA) with polyvinylpyrrolidone (PVP), followed by a centrifuge process. This allows one-step formulation of a polymer stabilised graphene ink. For MXene inks, I design a multi-solvent system for binder-free ink formulation. The …

Toward Rapid Silica Analysis of CPDM Samples using Portable Fourier Transform Infrared Spectrometry
… involves submerging CPDM filter stubs in 5 mL of isopropyl alcohol (IPA) and shaking them for 1 minute, followed by deposition of the dust onto a 25-mm polyvinyl chloride (PVC) filter using a syringe-based system. The PVC filter was then scanned at four 8-mm offset locations at 90° intervals from …

Biotreatment of waste streams containing isopropyl alcohol and copper from semiconductor manufacturing
… for treating waste streams containing isopropyl alcohol (IPA) and copper. A consortium of bacteria capable of degrading IPA was selected and acclimated. This consortium was immobilized on activated carbon and used as packing for a fluidized-bed reactor. The bioreactor was able to …

Planar integrated optical waveguide chemical sensors and novel transducer layer materials
… along with a solution-phase sensor for aqueous isopropyl alcohol (IPA) in Chapter 4. An IOW-based humidity sensor utilizing a completely non-sol-gel based transducer layer is also reported (Chapter 5). The humidity sensors were found to exhibit limits of detection of below 1% RH (down to 50 ppm …

Micro-patterned plasma and ultra-violet ozone modification of polymer surfaces.
… (i) plasma deposition/modification of n-Hexane, isopropyl alcohol (IPA) and acetone, and (ii) an Ultra-Violet/Ozone (UV/Ozone) oxidation treatment have been investigated as methods of influencing cell attachment behaviour. In particular, the effects of the surface oxygen chemistry, surface …

The effect of specific phospholipids that may have a possible role in propagating or inhibiting glioma
… untreated cells and treated cells with 0.002% isopropyl alcohol (IPA). In contrast, Phospholipon ® 90H was found to enhance the growth of 1321N1 and 005-3 cell lines and this effect was significantly (P 'C 0.05) larger when compared to the effects of Lipoid S-lOU and L-aphosphatidylcholine. …

Instabilities of volatile films and drops
… emphasis on the novel instability observed when isopropyl alcohol (IPA) is deposited on a monocrystalline silicon (Si) wafer. This instability is characterized by emission of drops ahead of the expanding front, with each drop followed by smaller, satellite droplets, forming the structures which …

Growth and characterization of epitaxial graphene films by Molecular Beam Epitaxy
Growing macroscopic graphene films with the aim of making graphene commerically viable is being researched a lot recently. Although graphene isolated by exfoliation of Highly Oriented Pyrolytic Graphite (HOPG) crystals has been in place for sometime now, its micro sample size has triggered the …
