32 PCB007 MAGAZINE I APRIL 2019 Weller Tools is sponsoring the annual stu- dent fee for IPC student members, providing students access to industry produced video courses, IPC standards, and the benefit of IPC membership including additional industry courses at member discounted rates. Calumet Electronics, another critical indus- try partner, is helping college students at Mich- igan Technical University enter the electronics sector better prepared with specific knowledge and skills, giving them an advantage in the job market. Companies benefit because their job candidates come to the table with specific, in- dustry knowledge. As someone who values education on a day- to-day basis and as an academician (I hold an Ed.D.), finding ways to make education more available to more people is very important to me, particularly in the electronics industry, suffering from a critical skills gap. I am so en- couraged by the support and generosity of the industry as we work to secure additional fund- ing to make engineering careers accessible to interested students regardless of their financial situation. We welcome your help and participation. If you are interested in sponsoring a name-brand- ed scholarship to enhance the academic pur- suits of the up and coming workforce, please reach out to Charlene Gunter du Plessis, di- rector of strategic partnerships and programs, at CharleneGunter@ipc.org. You can also visit www.ipcef.org for more information. Let's build a strong and competitive work- force together.

Physics and Astronomy in the School of Arts and Scienc- es at Rutgers University–New Brunswick. "Previously, to change the intensity of photoluminescence, you had to change the temperature or apply enormous pressure to a crystal, which was cumbersome and costly. We can do it simply within a small electronic device at room tempera - ture." Understanding photoluminescence is important for de- signing devices that control, generate, or detect light. The scientists discovered that defects in crystals reduce the emission of light and applying voltage restores the intensi - ty of photoluminescence. An important next step would be to investigate different types of perovskite materials, which may lead to better and more efficient materials where pho - toluminescence could be controlled in a wider range of in- tensities or with a smaller voltage. The study included lead author Hee Taek Yi in Rutgers' Department of Physics and Astronomy and co-authors Assistant Research Professor Sylvie Rangan and Professor and Department Chair Robert A. Bartynski. (Source: Rutgers University) Scientists from Rutgers University have found a new way to control light emitted by exotic crystal semicon - ductors, which could lead to more efficient solar cells and other advances in electronics. The study was published in Materials Today. Their discovery involves crystals called hybrid perovskites, and they have shown great promise for use in solar cells. The finding could also lead to novel electronic displays, sensors, and other devices activated by light and bring increased efficiency at a lower cost to the manufac - turing of optoelectronics. The Rutgers-led team found a new way to control light (known as photoluminescence) emitted when perovskites are excited by a laser. The intensity of light emitted by a hy - brid perovskite crystal can be increased by up to 100 times by adjusting the voltage applied to an electrode on the crystal surface. "To the best of our knowledge, this is the first time that the photolumines- cence of a material has been reversibly controlled to such a wide degree with voltage," said senior author Vitaly Pod - zorov, a professor in the Department of Creating Better Solar Cells
