![]() ![]() The girls were good although the girl Minaz who played Karan Wahi's girlfriend felt a little raw, maybe it was her character I dont know. I have never seen any of their work before but these actors were really good. ![]() The lead actors Akshay Oberoi and Karan Wahi were really good. The dialogues felt so real as though you were hearing your friends talk. ![]() The show is classy, the acting, music, writing and direction so well done it felt like an international Netflix show. I totally binge watched it into the night. I liked the trailer and then watched the show. I don't watch anything that is not on Netflix or Amazon Prime but I decided to watch the trailer before watching the show. The research was published in the academic journal Nanotechnology.Watched this show after a colleague in office highly recommended it. The invisible codes can still be read after paper has been folded many times and can also be printed other materials, including glass and flexible plastic film, so they could be used for a variety of products vulnerable to faking. Once lit up with the laser, the code can be scanned with a mobile phone, but the technique allows deeper levels of security with the ability to conceal information that can only be read with a microscope. "We can also change our parameters to make it even more difficult to counterfeit, such as controlling the intensity of the upconverting light or using inks with a higher percentage of nanoparticles," said Jeevan Meruga, who led the research. The process is known as 'upconversion' where the nanoparticles absorb photons at a certain wavelength and then emit them at a shorter wavelength visible in normal light. The invisible QR code, made by scientists at the University of South Dakota and South Dakota School of Mines and Technology, is made of tiny nanoparticles mixed into fluorescent ink, which can only be seen when illuminated with a near-infrared laser. ![]() Researchers have found out how to print them with inks that are only visible under laser light, giving them potential in the fight against fake banknotes and counterfeiting, which the OECD estimates costs the world economy more than $250 billion a year. Smartphones can scan them in printed adverts to navigate to company websites. Scientists in the United States have made an invisible version of square modern barcodes using nanoparticles and fluorescent ink to help in the fight against counterfeiting.īlocks of black and white Quick Response (QR) codes are increasingly common in marketing and can hold a hundred times more information than traditional barcodes. ![]()
