Nanosecond Pulsed Laser Processing of Metals and Welding of Metal-Glass Nanocomposites
… pulsed lasers are used as the tools to generate microstructures on metal and glass. The applications of these structures are described too. The production of micro structures is demonstrated using diode-pumped solid state (DPSS) Nd:YVO4 lasers operating at wavelengths of 532nm or 1064 nm. The …

Surface Microstructure Evolution of Metallic Specimens Using the Large Chamber Scanning Electron Microscope
… electron microscope (LCSEM) to interrogate the surface microstructure evolution of metallic specimens has been carried out. The LC-SEM located at Western Kentucky University is the largest instrument of its type at any university in the world. As such, unique measurements can be performed due to …

Surface structure enhanced microchannel flow boiling of low surface tension fluids
… been successfully mitigated by the addition of surface microstructures. Thermohydraulic performance in terms of critical heat flux (CHF) and heat transfer coefficient (HTC) have also benefited from surface modification, without significantly adding to the overall flow pressure drop. For some …

Wear Mechanism/microstructure Relationships for Laser Processed Cast Iron (Erosion, Abrasion, Martensite, Transformation)
… processing to produce novel, non-equilibrium surface microstructures in cast iron and (2) investigate the basic wear mechanisms of these non-equilibrium microstructures. Three kinds of microstructures can be produced by this laser processing. A very hard feathery microstructure ((TURN)100 HV), …

Engineering Microbubbles with the Buried-Ligand Architecture for Targeted Ultrasound Molecular Imaging
… weight difference. Microbubbles with various PEG surface architectures were formulated, and ligands with large molecular weight difference were used to conjugate to the microbubbles in order to study the feasibility of generating targeted microbubbles using the post-labeling technique. It was …

Investigating wetting characteristics on microstructured surfaces for superhydrophobicity and metal microcasting
The engineering of liquid behavior on surfaces is important for infrastructure, transportation, manufacturing, and sensing. Surfaces can be rendered superhydrophobic by microstructuring, and superhydrophobic devices could lead to practical corrosion inhibition, self-cleaning, fluid flow control, …

Effects of Laser Shock Peening on Residual Stress, Texture and Deformation Microstructure of Ti-6Al-4V Alloy
Laser shock peening (LSP) is a novel surface treatment process that generates deep compressive residual stresses and microstructural changes and thereby dramatically improves fatigue strength of critical metal aircraft engine parts. In the past, researchers have evaluated the mechanical effects of …

Photochemische Fixierung von Strukturen in Grenzflächen mit polymeren Bürsten
Binäre Polymerbürsten bestehen aus zwei verschiedenen Polymertypen, die nebeneinander auf dem gleichen Trägermaterial verankert sind. Wenn diese Polymere unterschiedliche Benetzungseigenschaften haben, können damit schaltbare Oberflächen produziert werden. Abhängig vom Lösungsmittel, dem man die …
