Directional Droplet Transportation on Microchannels

Lanling Chu, Yunzheng Wang, Xuemei Ge
In recent years, anisotropic wetting surfaces have attracted wide scientific attention for both fundamental research and practical applications. Directional transportation of droplets, as an efficient method to conduct droplet motion, has attracted great interest in research and industrial fields. Nevertheless, the great challenges in its application focus on these aspects such as sample conservation, velocity, distance, precision and driving force. Very recently, some research highlights were p...

Wettability and Surface Morphology Investigation of RGP Eye Contact Lens Irradiated by 193 nm Excimer Laser

Tayebeh Ariyafar, Ali Pourakbar Saffar, Peyman Tajalli, Habib Tajalli
In this work, Rigid gas permeable (RGP) contact lenses based on Fluoro Silicone Acrylate, were irradiated by using 193 nm ArFexcimer laser, at 1 Hz pulse repetition rate with 75 mJ/pulse energy to improve surface wettability. We investigated the morphology of the ablated area by imaging the surface modification with Atomic force microscopy (AFM) with roughness analysis and Scanning electron microscopy (SEM). Characterization techniques were performed too via contact angle measurement in order to...

Prospects of Introduction of Fiber Lasers for Laser Heat Treatment of Ferrous Metals

Vladislav Somonov
The article reflects the results of the study of the process of hardening of steels radiation fiber laser and the increase of productivity of process of laser hardening due to implementation of fiberoptic lasers instead of CO2 and the increase of the coefficient of absorption of laser radiation and the exclusion of the necessity to use absorbing coating. The research studied the structure of the hardened layer, compared with the structure of the obtained on CO2 laser, and p...

Surface Modification and Dielectric Response Investigation of Cellulose Acetate Membrane Treated by ArF Excimer Laser

Ali Pourakbar Saffar, Babak Jaleh, Parviz Parvin, Pikul Wanichapichart, Mahdi Farshchi-Tabrizi

Lasers are used to modify the surface morphology, crystallinity, chemical composition, reactivity and resistivity of polymer surfaces. In this work, several cellulose acetate membranes were exposed by ArF excimer laser, 193 nm, at 2 - 20 UV pulses, with 100 - 350 mJ/pulse energy, at 1 Hz pulse repetition rate. Characterization techniques viz. Fourier transform infrared spectroscopy (FTIR), Contact angle measurement, Scanning electron microscopy (SEM), At

Formation of TiO2 Nanopores by Anodization of Ti-Films

Patricia M. Perillo,Daniel F. Rodríguez
Titania nanopores were fabricated on silicon substrate. Ti thin films (600 nm) were first deposited by radio-frequency (RF) magnetron sputtering at two substrate temperatures and then anodized in glycerol electrolytes containing NH4F. The morphology and structure were identified by means of scanning electron microscopy (SEM), X-ray diffractometry (XRD). The effect of the temperature on the Ti thin films deposited by RF magnetron sputtering and the applied voltage on nanopore morphology were inve...
