POSTECH Develops World’s First Pixel-Based Local Sound OLED with Multi-Speaker Functionality on a Real Working 13-Inch Tablet sized OLED Display.
Analysis has shown a boulder weighing almost 1,200 tonnes in Tonga is one of the largest known wave-transported rocks in the world, providing new insights into the Pacific region’s history and risk of tsunamis.
A study by scientists at Nanyang Technological University, Singapore (NTU Singapore) has found that implementing robust air pollution control measures could mean Southeast Asian countries prevent as many as 36,000 ozone-related premature deaths each year by 2050.
A metamaterial is a composite material that exhibits unique properties due to its structure, and now researchers have used one featuring a small sawtooth pattern on its surface to move and position objects underwater without touching them directly. Adjacent speakers exert different forces on the material based on how the sound waves reflect off it, and by carefully targeting the floating or submerged metamaterial with precise sound waves, researchers can push and rotate the object attached to it.
