Nano-Sandwiching Improves Heat Transfer, Prevents Overheating in Electronics
Sandwiching two-dimensional materials used in nanoelectronic devices between their three-dimensional silicon bases and an ultrathin layer of aluminum oxide can significantly reduce the risk of component failure due to overheating, according to a new study published in the journal of Advanced Materials led by researchers at the University of Illinois at Chicago College of Engineering. Many of today’s silicon-based electronic components contain 2D materials such as graphene. Incorporating 2D materials like graphene — which is composed of a single-atom-thick layer of carbon atoms — into these components allows them to be several orders of magnitude smaller than if they were made with conventional, 3D materials. In addition, 2D materials also enable other unique functionalities. But nanoelectronic components with 2D materials…

UIC, MEE. Certificate
Master of Energy Engineering Program at UIC Offering Two New Graduate Certificates
Earning a master’s degree is not an option for everyone. To provide a choice for busy engineers who want to advance their careers, UIC is offering two new opportunities. The Master of Energy Engineering program in the Department of Mechanical and Industrial Engineering at UIC has added two graduate certificates that focus on two special areas of interest within its program. Apart from its Master’s Degree, the program is offering certificates in Energy Efficient Building Design and Power Generation. The Energy Efficient Building Design certificate focuses on energy usage and efficiency technologies for commercial buildings. The courses cover heating, ventilating and air-conditioning, industrial energy management, energy markets and contracting and design of energy efficient buildings. The Power Generation certificate is…

UIC Hosts International Conference on Liquid Atomization and Spray Systems
The University of Illinois at Chicago and Spraying Systems Co. hosted researchers, industrialists, students and academics from all backgrounds for the 14th International Conference on Liquid Atomization and Spray Systems - ICLASS 2018. The conference, which is hosted in the United States once every nine years, was held from July 22 through the 26, and served as an excellent opportunity to showcase UIC to nearly 500 researchers from around the world. The event is the largest conference the Institute for Liquid Atomization and Spray Systems has hosted to date. ICLASS provides an opportunity for the international community to convene and share information, experiences and technical advances in liquid atomization and spray system optimization. “Several UIC faculty members work in areas…

First-Ever 3D-Printed Electrolyte for Lithium-Ion Batteries
For the first time, researchers have successfully printed a complete, albeit experimental, lithium-ion battery including a solid-state electrolyte. While electrodes have been produced using 3D-printing technology before, researchers at the University of Illinois at Chicago College of Engineering have printed a stable, yet flexible, solid-state electrolyte using an elevated-temperature extrusion printing technique. They report their findings in the journal Advanced Materials. Lithium-ion batteries are commonly used in home and portable electronics, and in some motor vehicles. They function by the movement of lithium ions from the negative electrode through an electrolyte, which can be liquid or solid, to the positive electrode during discharge and then back during the charge phase. Mass producing these batteries is a laborious and expensive process. The electrodes and…

Liquid Microscopy Technique Reveals New Problem with Lithium-Oxygen Batteries
Using an advanced, new microscopy technique that can visualize chemical reactions occurring in liquid environments, researchers have discovered a new reason lithium-oxygen batteries — which promise up to five times more energy than the lithium-ion batteries that power electric vehicles and cell phones — tend to slow down and die after just a few charge/discharge cycles. They report their findings in the journal Nano Energy. “What we were able to see for the first time is that lithium peroxide develops in the liquid electrolyte of lithium-oxygen batteries, and is a contributor to the slow down and ultimate death of these batteries,” said Reza Shahbazian-Yassar, associate professor of mechanical and industrial engineering in the University of Illinois at Chicago College of…

AIAA at UIC win in New Mexico 2018 IREC Spaceport
Engineering Students Blast to First-Place at International Competition
The UIC chapter of the American Institute of Aeronautics and Astronautics (AIAA) recently won first place in the “30K Solid Rocket-Student Research and Developed Components” category during the second annual Spaceport America CUP at the Las Cruces Convention Center in New Mexico. The team competed with its first student built motor as they successfully flew it and recovered it. This is the first time UIC has won first place at IREC. The team also captured a third-place win with its commercial rocket. Both rockets were flown to approximately 30,000 feet as they topped schools like Purdue, Stanford, and the University of Minnesota. The Spaceport America Cup is a partnership between the Experimental Sounding Rocket Association (ESRA) and the New Mexico…
