“Emanuil Yanev talks about his PhD work modifying 2D materials to push their light-producing limits. In 2015, a class of two-dimensional materials called the transition metal dichalcogenides (TMDs) entered the scientific limelight for their ability to produce just one particle …
“Researchers create a compact, all-optical device with the lowest microwave noise ever achieved for an integrated chip. In a new Nature study, Columbia Engineering researchers have built a photonic chip that is able to produce high-quality, ultra-low-noise microwave signals using …
“In 2021, lanthanide-doped nanoparticles made waves — or rather, an avalanche — when Changwan Lee, then a PhD student in Jim Schuck’s lab at Columbia Engineering, set off an extreme light-producing chain reaction from ultrasmall crystals developed at the Molecular Foundry …
“Columbia Engineers design a robot hand that is the first device of its kind to join advanced sense of touch with motor-learning algorithms — it doesn’t rely on vision to manipulate objects Think about what you do with your hands …
News New “Camera” with Shutter Speed of 1 Trillionth of a Second Sees through Dynamic Disorder of Atoms
“Speeding up a camera shutter a million million times enables researchers to understand how materials move heat around and is a major step in advancing sustainable energy applications. Researchers are coming to understand that the best performing materials in sustainable …
“A 2.6nm-long single molecule wire has quasi-metallic properties and shows an unusual increase of conductance as the wire length increases; its excellent conductivity holds great promise for the field of molecular electronics. As our devices get smaller and smaller …
“Researchers at Columbia and Google Quantum AI have developed an algorithm that uses the most quantum bits to date to calculate ground state energy, the lowest-energy state in a quantum mechanical system. The discovery could help make it easier to …
“Using 2D materials, researchers have built superconducting qubits that are a fraction of the size of previous qubits, paving the way for smaller quantum computers. For quantum computers to surpass their classical counterparts in speed and capacity, their qubits—which …
“The results relied on a cleaner technique to manipulate the flow of electricity, giving graphene greater conductivity than metals such as copper and gold, and raising its potential for use in telecommunications systems and quantum computers. The device you are …
“Spin transition discovered in the Earth’s mantle; finding will improve understanding the Earth’s interior, and enable better understanding of tectonic events including volcanic eruptions and earthquakes. The interior of the Earth is a mystery, especially at greater depths …
