Seoul National University’s College of Engineering announced that a research team led by Professor Chul-Ho Lee from the Department of Electrical and Computer Engineering has outlined a comprehensive roadmap for the ‘gate stack’* engineering, a core technology for two-dimensional (2D) transistors, which are attracting attention as next-generation semiconductor devices.

*Gate stack: A layered structure composed of dielectric and metal materials placed above the conductive channel in a transistor, used to electrostatically modulate channel conductance.

Researchers at Seoul National University have unveiled a groundbreaking thermal management technology capable of selectively implementing cooling and heating functions using a single material and process, without requiring electricity.

The technology developed by Professor Seung Hwan Ko's research team in the Department of Mechanical Engineering at SNU is drawing attention as an innovative solution that replaces existing complex processes. It enables the same transparent silicon polymer material to be processed into either a cooling or heating surface simply by adjusting the intensity of laser output, without consuming electricity.

Researchers at Lehigh University are developing a faster, more accurate way to predict how metals solidify during 3D printing and other additive manufacturing processes. Supported by a three-year, $350,000 grant from the National Science Foundation, assistant professor Parisa Khodabakhshi is creating a physics-based, data-driven model that connects manufacturing process parameters with the resulting material microstructure. The approach aims to replace costly trial-and-error methods with efficient simulation tools that can guide the design of high-performance metal components. The project’s outcomes could accelerate innovation across industries that rely on advanced manufacturing—such as aerospace, automotive, and healthcare—while helping train the next generation of engineers and scientists.

Accurate land cover maps are fundamental to urban planning, environmental monitoring, and sustainable development. 

In JASA Express Letters, researchers evaluate the relationships between sound quality, speech recognition, and quality-of-life outcomes for cochlear implant (CI) users. They found CI sound quality leads to a 32% variance in users’ quality of life — in contrast, speech recognition has virtually no predictive power over quality of life. In their study, speech recognition only correlated with sound quality under noisy conditions, suggesting it is particularly relevant in situations with background noise and different sound sources — in other words, the real world.

MIT engineers designed a control mechanism, known as DIAL, that allows them to establish a desired protein level, or set point, for any synthetic gene circuit.
