President Benigno Aquino III has approved the Chemistry Profession Act, which regulates and modernizes the practice of chemistry in the Philippines. Republic Act 10657, which Aquino signed last March 27, repealed Republic Act 754, the earlier law that regulated the practice of chemistry in the country. The new law expands the definition of chemistry and the scope of its professional practice. R.A. 10657 defines chemistry as the study, analysis, modification and calculations of physico-chemical or biochemical properties of matter. The newly signed legislation also mandates the creation of Professional Regulatory Board of Chemistry, which will be composed of three members appointed by the President. Members of the board will serve three-year terms. The board is tasked to supervise and regulate the practice of the chemistry profession in the Philippines, and to come up with implementing guidelines for the new law. Just like the repealed law, R.A. 10657 also requires an individual who wants to practice chemistry and in the Philippines to pass the licensure examination given by the Professional Regulatory Board of Chemistry.

Once again, Nicholas Sparks is bringing his signature romantic stylings to the big screen with The Longest Ride, in theaters Friday. Starring Scott Eastwood and Britt Robertson as what else? star-crossed lovers, the movie joins a long line of Sparks movies crafted precisely to make the heart ache. While the jurys still out on The Longest Ride, history has taught us that the fate of a Sparks adaptation can depend largely on whether its leads mesh like peanut butter and jelly, or conversely, if they mesh like peanut butter and turkey. So lets rank, from worst to best, the stars chemistry in each of Sparks movies. Before she was Piper Chapman, Schilling was busy trying to muster a bit of interest in the kid from High School Musical. This movie made it very clear that the only woman Duhamel should be focusing on is Ms. Fergalicious and that the only thing Hough should be paid to portray is the part of reality TV dancer. The first adaptation of a Sparks novel places its characters in a dynamic that feels dated and inauthentic, something the actors cant overcome. It wasnt that the films two big stars didnt have any sexual tension … Continue reading →

In Game Of Thrones, Valyrian steel was forged during the Valyrian Freehold It is said to be sharp, light, strong, heat resistant and dark with patterns Scientist has studied which materials could create a similar, real life sword And concludes it's not a steel at all, but is instead a metal matrix composite By Victoria Woollaston for MailOnline Published: 08:51 EST, 7 April 2015 | Updated: 15:09 EST, 7 April 2015 In Game of Thrones, the secret to forging super-light and strong Valyrian steel swords was said to have been lost with the Doom of Valyria. But, despite its fictional basis, a scientist has investigated whether it would be possible to make a similar weapon using bona fide chemistry. By studying the composition of modern steel, welding techniques and assessing all the characteristics of Valyrian steel, he concludes it isn't a steel at all, but instead is a metal matrix composite. Scroll down for video According to the Game of Thrones books, Valyrian steel is a form of super strong and light metal forged when the Valyrian Freehold governed Essos and covered more than half the known world. Ned Stark, played in the HBO adaptation of the books by Sean … Continue reading →

April 6, 2015 Credit: American Chemical Society/YouTube Brett Smith for redOrbit.com @ParkstBrett With the fifth season of the fantasy epic Game of Thrones is set to begin next Sunday on HBO, the American Chemical Society recently asked the question: Could modern chemistry be used to make the epics legendary Valyrian steel swords? The magical metal is said to be crafted from dragons fire and ancient magic, but what if you dont have access to either? In an online video, the ACS Ryan Consell first broke down the characteristics of Valyrian steel based on its description in the show and the George R.R. Martin books on which the show is based. This super-material is described as being incredibly sharp, light, strong, super-heat resistant and dark in color with very distinct ripple patterns, Consell said. Strength and sharpness is gonna require a bit of a fancy balancing act. Perhaps a modern supermaterial Consell went on to say that to hold an edge, metal needs to be very hard. However, the harder a metal is the more brittle it becomes. For these reasons, I might recommend a spring steel, he said, maybe something with 0.6 percent carbon, and a couple percent silicon and … Continue reading →

The most sought-after blades in Westeros are made from Valyrian steel, forged using ancient magic. But could you make your own Valyrian steel sword using real-life chemistry? Reactions collaborated with cosplaying chemistry fanatic and material scientist Ryan Consell to see if we could blend metallurgy with Westerosi magic.
