Surface Modification and Characterization of Polylactic Acid (PLA) 3D printed structures for Cell culture applications.

Pokharna P., Ghantasala M., Rozhkova E., Western Michigan University, US

The main aim of this research is to understand the surface modification effects and improve the surface properties of 3D printed scaffolds that would be biocompatible and support the growth and proliferation of cells. Polylactic [...]

Surface modification of aluminum doped zinc oxide (AZO) anodes with CFx plasma treatment and nanoscale WOx layers for enhanced electro-optical performance in OLEDs

Kumar Jha J., Santos-Ortiz R., Sun W., Du J., Shepherd N.D., University of North Texas Denton, US

CFx plasma treatment and WOx interfacial layer deposition were performed on AZO films to improve its workfunction for transparent conducting oxide (TCO) anode application in the organic light emitting diodes (OLEDs). As shown in Figure [...]

Thermal Transformation of Aqueous Lignin Suspension into Nanoparticle Dispersion and Its Associative Properties

Zhaoquing L., Gast J.C., Bottorff K.J., Solenis LLC, US

LIGNIN IS THE SECOND MOST ABUNDANT BIOPOLYMER. NANOPARTICLE DISPERSIONS OF LIGNIN WERE OBTAINED BY SIMPLY HEATING IN A CONTROLLED MANNER A PARTIALLY NEUTRALIZED LIGNIN SUSPENSION IN WATER. THE LIGNIN NANOPARTICLES WERE FOUND TO FORM STABLE [...]

Nanoanalysis of Gas Assisted Ion Etching of High Density Polyethylene using FIB/SEM Platforms for the Development of Functional Surfaces

Sezen M., Bakan F., Sabanci University, TR

Although soft matter, such as polymers, are very much prone to react on electron/ion beam irradiation, it is well possible to turn degradation dependent physical/chemical changes from negative to positive when materials are exposed to [...]

Surface modification of nanocrystalline LiCoO2 particles with rare earth oxides using polymeric resin process

Nageswara Raoa B., Venkateswarlub M., Satyanarayana N., Pondicherry University, IN

Among the available positive electrode materials, layer structured LiCoO2 is the most preferred one in commercial Li-ion batteries. However, LiCoO2 exhibits a capacity fading at high rates due to its structural instability and reactivity with [...]
