Use of Inert CVD Coating for Protein, Corrosion, and Moisture Resistance in Bioanalysis Applications

Patterson L., SilcoTek Corporation, US

The desire to enhance the surface properties of base materials is especially prevalent in life science applications [1]. In order to keep up with evolving patient needs and clinical innovations, manufacturers in the medical industry [...]

Production of NSAID pharmaceutical molecular liquids via RESS processing

Kumar Sharma S., Woldetsadik A.D., Magzouband M., Jagannathan R., New York University Abu Dhabi, AE

Abstract One of the prominent challenges in pharmaceutical drug development is the poor aqueous solubility of many pharmaceutical drugs and subsequently, their reduced bioavailability. Traditional drug delivery strategies are not target specific in the body [...]

A Bulk, Low Energy Surface Treatment for Three Dimensional Substrates via CVD Processing

Smith D., Patterson L., SilcoTek Corporation, US

There are myriad potential applications and a significant need for low energy surfaces. The gas-phase modification of three dimensional structures, such as fittings, tubing, valves, or manifold blocks, in high volume, to give hydrophobic and [...]

Coating Resistance to Biofouling Inception for Freshwater Vehicles

Malm P., Krishnan G., Loth R., Steele A., Bayer I., University of Virginia, US

Preventing biofouling in natural bodies of freshwater is important for a wide variety of applications. The relationship between surface properties and antifouling has been the subject of many recent studies, with primary focus on long-term [...]

Fluorination effects on tribological characteristics of hydrogenated amorphous carbon thin films

Rubio-Roy M., Portal S., Polo M.C., Pascual E., Bertran E., Andújar J.L., Universitat de Barcelona, ES

Hydrogenated amorphous carbon (a C:H) films are good candidates for biomedical applications, requiring smooth surfaces, biocompatibility and singular tribological characteristics. The addition of elements to a C:H films, such as oxygen, silicon, fluorine or metals, [...]

Composite Carbon Nanostructures as Promising Carriers for Gaz Analysis

Majoli L., Evstratov A., Guillot J.-M., Rouvière A., Baussand P., Ales High Mining School, FR
