Nanoscience is well on its way to establishing itself as one of the critical technologies of the 21st Century. Just as semiconductors gave rise to computers, smart phones, the Internet, medical devices, and an endless stream of consumer products, nanoscience is enabling the development of new technologies in fields as diverse as electronics, medicine, photonics, energy, and quantum physics. Nanoscale constructions provide this flexibility for two reasons. First, they are small and precise enough to interact with molecules in entirely new ways. Nanomedicines, for example, often encapsulate drugs in molecular packages decorated with segments of molecules that enable them to target specific organs and diseases, and, once there, convince those cells to ingest the medication. Metal-organic frameworks, complex molecules engineered to reduce energy use in chemical reactions and capture carbon emissions from combustion, are another example. Second, and more intriguingly, nanoscale devices are closer in size to electrons and photons, and may interact with them in ways that are fundamentally different from the behavior of larger objects. For example, metamaterials, arrays of nanoscale structures, can bend light around an object to make it appear invisible. Nanoscale electronics can exploit quantum phenomena, like electron spin, energy waves, and quantum states to capture, store, and process information. As these technologies and other emerging applications reach commercialization, they are certain to change nearly every sphere of life.

2012 Kavli Prize in Nanoscience: A Discussion with Mildred Dresselhaus

Aug 03, 2012

Mildred Dresselhaus, this year's winner of the Kavli Prize in Nanoscience, has had a long and illustrious career in physics. Dubbed "The Queen of Carbon" by her peers, she was instrumental in unlocking the secrets of carbon's electronic structure and the mysterious forms it takes on in nature.

How Atomic Scale Devices Are Transforming Electronics

Apr 28, 2012

With advances such as a working transistor made from a single atom, scientists and technologists are learning to measure and manipulate matter to create fundamentally different electronic devices. 

North to the Future: The Merging of Bio and Nano

Apr 17, 2012

Seventeen prominent researchers gathered in Ilulissat, Greenland — a town where dogsleds are common and townspeople sail in a fjord filled with enormous icebergs — to discuss what would happen as nanoscience and biology blended together at the level of cells and molecules. 

Extreme Machines: What Science Needs from Computers

Apr 17, 2012

Computers are the workhorses of science. Without their power to crunch numbers, control instruments, turn raw data into intelligible patterns or pictures and test theories with simulations, most of what we now know about ourselves and the universe might still be a mystery. 

Fighting Cancer with Nanoparticle Medicines ― Mark E. Davis

Mar 07, 2012

Why is there excitement about nanoparticle medicine (nanomedicines) for fighting cancer? In this video, Dr. Mark E. Davis presents the current understandings of why these engineered, nanosized medicines may provide game-changing ways to treat cancer.

Joanna Aizenberg Talks "Extreme Biomimetics" at TEDxBigApple

Mar 06, 2012

A TEDxBigApple video presentation of KIBST Co-Director Joanna Aizenberg, describing the full breadth of her bio-inspired research, which draws on the genius of nature to create the materials of the future.

Fighting Cancer with Nanotechnology

Feb 09, 2012

Will advances in nanotechnology be a game changer for the treatment and diagnosis of cancer? Four pioneers in the field — Drs. Anna Barker, Mark E. Davis, James Heath and Michael Phelps — discuss where things stand and what the future holds.

Charging Up the Auto Industry

Jan 27, 2012

The 2006 documentary “Who Killed the Electric Car," suggested that electric cars would forever be just around the corner, never fully arriving in the U.S. market. But electric and hybrid vehicles are now available from a slew of major car manufacturers. 

Disturbing the Nanosphere

Oct 17, 2011
Cornell

Cornell University researchers, including KIC’s J.C. Séamus Davis and post-doctoral fellow Mohammad Hamidian, deliberately create atomic-level disorder in order to probe the workings of heavy fermion compounds. 

Pollock: Artist and physicist?

Jul 27, 2011
Harvard

At a glance, a painting by Jackson Pollock can look deceptively accidental: just a quick flick of color on a canvas.
