Oil spills are considered to be a major environmental disaster, being a slippery substance by itself whenever it is on a microscope slide or when it is leaked into the ocean. In fact, it costs a whole lot to clean up an oil spill, but what is worse would be the negative impact on the environment. Since prevention is always better than cure, how about utilizing special surfaces which were specially designed in order for it to counteract oil’s naturally low surface tension? This is exactly what the researchers over at the University of Missouri have worked on, by developing a method so that it can control the unpredictable liquid.
Known as “virtual walls”, this creation by Missouri engineers might eventually consign oil spills to history. Professor Jae Kwon Kwon and graduate student Riberet Almeida of Missouri’s school of engineering work have plenty of faith in their material which they hope would eventually lower the chances of oil spills. Kwon shared, “Our newly developed surface helped keep oil, which is normally unmanageable, in predetermined pathways making it controllable. We feel that oil-repellant surfaces can be widely utilized for many industrial applications, and virtual walls for low-surface tension liquids also have immense potential for many lab-on-a-chip devices which are crucial to current and future research technique.”
Do you play with a whole lot of World of Warcraft? If you have answered in the affirmative, then you might be pleased to know that patch 5.4.2 is now available to test out on the Public Test Realms (PTR). Those who would like to take part in the Public Test Realms will be able to enjoy giving patches a test run prior to its official release. Assuming you would like to do your bit to test and provide feedback, you can do so by copying your character and downloading the PTR client. After giving it a run around a few times, do remember to pay a visit to the PTR Discussion forum in order to talk over the patch, and should there be any issues or errors to clarify, it can be done over on the PTR Bug Report forum.
Among the changes made to the World of Warcraft Patch 5.4.2 PTR include “Intervene” that no longer removes movement-impairing effects on use. As for the talent Safeguard, it will continue to remove movement-impairing effects. Where “Raids, Dungeons, and Scenarios” are concerned, one ought to take note that Cross-Realm raid browser will now feature new categories for Mists of Pandaria World Bosses (Celestials and Ordos) and Flexible raid difficulty for Siege of Orgrimmar.
