Multifunctional Ceramic Thin Films for High-Performance Orthopaedic Implants
Bianchi M., Lopomo N., Boi M., Maltarello M.C., Liscio F., Marcacci M., Russo A., Istituto Ortopedico Rizzoli, IT
We describe here the deposition via a novel sputter-based electron deposition technique of functional ceramic thin films on the surface of the two main components of an orthopaedic implant: the load-bearing component and the segment [...]
Development Antifog Nanohybrid Consisting of Polyestyrene Recycled Matrix by Sol-Gel Process
A hybrid material consisting of SiO2 nanoparticles embedded in polystyrene recycled matrix has been developed. A polymer of polystyrene recycled functionalized (PSR-F) was used to influence the morphological and antifog properties of sol-gel synthesized silica [...]
Droplet actuation and droplet mobility manipulation on porous media by means of backpressure control
Synthesis of surfaces with special tunable wettability as well as transitions between various wetting states are now intensively studied both for understanding wetting principles as well as for practical applications. Herein we present an alternative [...]
Adhesion and friction between supported pH sensitive polymeric nanoparticles monolayers
The unique property of polymers responding to external stimuli has made this class of smart materials very promising for various applications. A particular approach that has been widely used over the past decades is the [...]
Advanced Coating for Energy Applications
Quest for oil and gas has increased in the past few decades and the industry is in a constant change of flux to identify new oil reserves and extraction methods to recover oil and natural [...]
Durable Icephobic Coatings
Constantinou J., Panwar A., Mitra S., Nahum T., Wagner M., Dodiuk H., Barry C., Kenig S., Mead J., University of Massachusetts-Lowell, US
Accumulation of ice on the surfaces of windmills, airplanes, ships and telecommunications equipment hinders the efficient functioning of this equipmement, which can be overcome by the use of an icephobic coating. Prior work has established [...]
Bio-Inspired Multi-gradient Structure Surfaces for Water Collection/Repellency
Biological surfaces with micro- and nanostructures display unique wetting functions. Since spider silk collects water through a combination of multiple gradients in a periodic spindle-knot structure after wet-rebuilding process, a series of functional fibers with [...]
3D Printered and Plasma Treated Superhydrophobic Mesh Filters for Oil-water Separation
Lee H.J., Lee S., Jo W., Lee H.J., Lee S., Moon M.-W., Korea Institute of Science and Technology, KR
We develop the 3D printed mesh filters with plasma treatment using a radio-frequency plasma-enhanced chemical vapor deposition (rf-PECVD) to control their surface wettability. The nano-sclae hairy structures on the meshes are created by plasma etching [...]
Mechanically Durable Superhydrophobic Nanocomposites from Acrylonitrile Butadiene Styrene (ABS)
We report on the development of nanocomposites based on a combination of ABS with hydrophobically modified fumed silica (HMFS). By tuning the ratio between the two materials we are again able to obtain static water [...]
Merino Wool Surfaces Made Superhydrophobic
Natural merino wool fibres have been used to fabricate wash-fast nonwoven textile surfaces with superhydrophobic and oleophobic properties. Wet felted samples were used to study the effect of the fibre diameter and the degree of [...]
Effect of Support Structure on Permeance of Thin Film Composite Membranes
The production of potable water has become a worldwide concern to meet the demand of a growing population. The reverse osmosis (RO) membrane is the leading technology for desalination installations to produce drinkable water, due [...]
Preparation and characterization of SAPO-34 nanoparticles-mixed matrix membranes (MMM) via combined phase separation method for CO2/CH4 gas separation application
Mixed matrix membranes (MMM) comprising of SAPO-34 zeolite nanoparticles in polyethersulfone (PES) matrix were fabricated via combined TIPS/NIPS phase separation method, which is critical for membrane performance, were synthesized and characterized. The performance of the [...]
Controlling Alignment in Cellulose Nanocrystal Coatings
Investigations on the rheology and phase behavior of aqueous CNC dispersions have been used to develop processes for making CNC coatings with controlled properties. We report how the interplay between dispersion microstructure, shear, and drying [...]
Hybrid Materials made up of Ionic Liquids Confined in Porous Silica and Chalcogenide
Ori G., Villemot F., Viau L., Vioux A., Massobrio C., Coasne B., UMI CNRS / Massachusetts Institute of Technology, US
Hybrid materials made up of an inorganic porous material filled with a room temperature ionic liquid (IL) represent a novel class of materials with promising applications. The structure and dynamics of IL confined in amorphous [...]
