The first practical floating solar hydrogen-generating device could lead to low-cost, sustainable hydrogen production

Posted on by Haptic

In a single hour, more energy from the sun hits the Earth than all the energy used by humankind in an entire year. Imagine if the sun’s energy could be harnessed to power energy needs on Earth, and done in a way that is economical, scalable, and environmentally responsible. Researchers have long seen this as Read more about The first practical floating solar hydrogen-generating device could lead to low-cost, sustainable hydrogen production[…]

An unconventional reversible chemical reaction at nanoscale that enables efficient carbon capture

Posted on by Haptic

A recent study led by Xi Chen, associate professor of earth and environmental engineering at Columbia Engineering, and Klaus Lackner at Arizona State University, reports an unconventional reversible chemical reaction in a confined nanoenvironment. The discovery, a milestone in clarifying the scientific underpinnings of moisture-swing chemical reaction, is critical to understanding how to scrub CO2 Read more about An unconventional reversible chemical reaction at nanoscale that enables efficient carbon capture[…]

Combating VR Sickness

Posted on by Haptic

Columbia Engineering Professor Steven K. Feiner and Ajoy Fernandes MS’16 have developed a method of combating virtual reality (VR) sickness that can be applied to consumer head-worn VR displays, such as the Oculus Rift, HTC Vive, Sony PlayStation VR, and Google Cardboard. Their approach dynamically, yet subtly, changes the user’s field of view (FOV) in Read more about Combating VR Sickness[…]

WiFi Capacity Doubled at Less than Half the Size

Posted on by Haptic

Last year, Columbia Engineering researchers were the first to invent a technology—full-duplex radio integrated circuits (ICs)—that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio. That system required two antennas, one for the transmitter and one for the receiver. And now the team, led Read more about WiFi Capacity Doubled at Less than Half the Size[…]
