SMART Investigates The Science Behind Varying Performance Of Different Colored LEDs
The findings pave the way to develop more efficient next-gen LEDs that cover the entire visible spectrum.
Researchers from the Low Energy Electronic Systems (LEES) interdisciplinary research group at Singapore-MIT Alliance for Research and Technology (SMART), MIT’s research enterprise in Singapore, together with MIT and National University of Singapore (NUS), have found a method to quantify the distribution of compositional fluctuations in the indium gallium nitride (InGaN) quantum wells at different indium concentrations.
InGaN light emitting diodes (LEDs) have revolutionized the field of solid-state lighting due to their high efficiencies and durability, and low costs. The color of the LED emission can be changed by varying the indium concentration in the InGaN compound, giving InGaN LEDs the potential to cover the entire visible spectrum. InGaN LEDs with relatively low amounts of indium compar
Study: Ride-Sharing Increases Urban Congestion
New research shows that ride sharing contributes to increased congestion and decreased transit ridership. April 28, 2021, 12pm PDT | Diana Ionescu | While ride-sharing has been credited with being more environmentally friendly than taxis and private vehicles, a new study from the the Future Urban Mobility (FM) Interdisciplinary Research Group (IRG) at Singapore-MIT Alliance for Research and Technology (SMART), MIT, and Tongji University assessing the impacts of ride-sharing on urban mobility in the U.S. found that the entrance of TNCs [Transportation Network Companies] led to increased road congestion in terms of both intensity and duration. The study also found that public transit ridership decreased by 8.9 percent, while private car ownership experienced an insignificant decrease of only 1 percent.

Professor Megan Warin, Research Leader, Robinson Research Institute / Director Fay Gale Centre for Research on Gender, University of Adelaide.
Megan Warin is a social anthropologist and a Fellow of the Australian Academy of Social Sciences and has over 2 decades of research experience in investigating how people attend to food and eating in everyday lives. Her research takes her into communities and homes where people often experience hardship and are trying to juggle many competing priorities in the context of family life. Poverty, under-employment, mental health and poor housing all impact on people’s capacity to eat, and to eat well. With colleagues, Megan has explored the ways in which women and mothers are positioned in many of the key debates around parenting and obesity, highlig
