27 November 2008. Quezon City, Philippines. A team of researchers from the National Institute of Physics, University of the Philippines has proposed tailoring the properties of Teflon by coating it with hydrogen to make it suitable for specific applications. Teflon or Polytetrafluoroethylene (PTFE) has gradually developed to become the seminal material in numerous applications. By virtue of its incredibly versatile characteristics, its potential use in a modern technological society appears limitless- ranging from electrical and electronics, food packaging and processing, biomedical, chemical and mechanical to agricultural and aeronautical applications. The ease with which the surface attributes of PTFE can be manipulated without altering its bulk composition suggests that the logical focus should be towards tuning PTFE surface to suit a particular application. Surface modification allows for the change and improvement of the property of a material, making the processed material more useful in various aspects. |

18 November 2008. Quezon City, Philippines. A collaborative research venture between the Philippines and Japan has shown that a single laser can be used to manipulate and perform microsurgery on cells. They manipulate cells using the principle of optical trapping where gradient forces of light attracts the cells towards the focus. By moving the focus of the beam using scanning mirrors, the optically trapped yeast cells are manipulated around the microscopic region of interest. On the other hand, dissecting the cells is achieved via non-linear optical absorption process. The team showed that a single Ti:Sapphire laser, which can be switched between continuous-wave (cw) and femtosecond (fs) pulse mode, can be used for both functions1. |

8 October 2008. Roskilde, Denmark. An international team of researchers from the Denmark, India and Germany proposed a novel technique for interferometric evaluation of angular displacements. Their method is carried out using phase retrieval to reconstruct the tilted wavefronts. The main advantage of their proposed technique is the simplicity of the setup since no optical elements other than the diffuser is required to reconstruct the wavefronts. |
