Preparation and characterization of Mo/Al layered thin films
The fabrication of bilayer and multilayer Mo/Al thin films using a conventional multi-target rf-diode sputter deposition system was studied. The films were deposited on glass and Si( 100) substrates. The as-deposited films were characterized with respect to their structure and composition profiles …

Surface tension and electroporation of lipid bilayers
Electroporation of lipid bilayers is widely used in DNA transfection, gene therapy, and targeted drug delivery and has potential applications in water desalination and filtration. A better, more thorough molecular understanding is needed, however, before such devices can be effectively used and …

Porous anodic aluminum oxide scaffolds; formation mechanisms and applications
… has been developed, based on anodization of Al/W bilayer films on substrates. When Al/W bilayer films are anodized and pores approach the Al/W interface, tungsten oxide forms and penetrates the alumina barrier oxide, in part, due to enhanced plasticity of the alumina layer. By selectively etching …

Novel Biomimetic Polymeric Nanoconjugates as Drug Delivery Carriers for Poorly Soluble Drugs
… of the drug loaded composite pharmaceutical films exhibited concentric spheres with two and three layers for the binary and ternary films respectively. This supports the evidence of internalization of ibuprofen by the polyelectrolyte complex. The FTIR and DSC results confirmed electrostatic …

Synthesis and Characterization of Poly(siloxane imide) Block Copolymers and End-Functional Polyimides for Interphase Applications
… with the imide as the included phase. Epoxy bilayer films of polyimide (amine end-functional and commercial Ultem™) and poly(siloxane imide) multiblock copolymers were prepared to evaluate the polymer-matrix interphase region. Atomic force microscopy (AFM) analysis of the bilayer films showed …

Pulsed Laser Deposited Iron Garnet Thin Films for Spintronics
… layering at a sub unit cell scale. Iron garnet films are suitable for next generation spintronic memories because of their low Gilbert damping and their growth with perpendicular magnetic anisotropy (PMA) which promote fast domain wall dynamics. Additionally, selection of rare earth ion and …

Optimization of the automated spray layer-by-layer technique for thin film deposition
… developed at MIT by the Hammond lab to build 25 bilayer films of poly (ally amine hydrochloride) (PAH) and poly (acrylic acid) (PAA). Each of the 10 operational parameters of this system are explored individually to isolate each parameter's effect on film thickness and roughness. The parameter …

Outer-core emission spectroscopy of the heavy alkalis and alkali-alkali metal alloys
… Emission intensity ratios observed for thin bilayer films support these findings. The anomalously large absorption edge widths observed in dilute alloys of K, Rb, and Cs in Li and Na are found also in the present emission spectra as well. The emission and absorption edges cross at half …

Development of functionalized materials through sol-gel route for applications in catalysis and surface protection
… have been compared with pure ZnO and bilayer films composed of TiO2 and of ZnO. Different photocatalytic tests have been performed and depending on the test the best photocatalyst was different. Then, to increase the economic interest, some dopant have been used. In addition of the …

Multi-channel tag based on fluid-suspended magnetic microparticles
… project uses micron lithography on thin film films of magnetic material which can be lifted off into solution to create an artificial ferrofluid of advanced materials. We hope to develop such a fluid with the same functionalisation which can be achieved through the thin film structures on a …

Pattern formation and magnetism in pulsed laser-induced self-organized nanostructures from single and bilayer metallic films
… nanosecond pulsed laser melting of thin metal films is attractive as a reliable and low cost method to create surface metallic nanostructures. The potential applications of these resulting structures are related to their magnetic, optical, plasmonic, and magneto-optical properties, such as in …

Development of ternary oxides for use in advanced front contacts in cadmium telluride solar cells by magnetron sputtering
… technology. Devices are composed of thin films which enable conversion of incident sunlight into electrical carriers and simultaneous transport of these carriers to an external load. At the front of the device, the layers should be highly transparent to minimize parasitic absorption while …

Dual Spin-Cast Thermally Interdiffused Polymeric Photovoltaic Devices
… voltage and other key electrical properties. Bilayer films of sequentially spin-cast donor and acceptor materials are exposed to various heat treatments in order to induce the interdiffusion. The depth profiles show concentration gradients in the donor and acceptor as a result of …
