The multidisciplinary team, led by Tobias Hanrath, associate professor in the Robert Frederick Smith School of Chemical and Biomolecular Engineering, and graduate student Kevin Whitham, has fashioned two-dimensional superstructures out of single-crystal building blocks. Through directed assembly and attachment processes, the lead selenide quantum dots are synthesized into larger crystals, then fused together to form atomically coherent square superlattices.

The school averages 320 children per year, 66% of whom, in 2014, receive free lunch, and 4% more receive reduced lunch. This large percentage of the school population is less likely to have: family backgrounds in the sciences and engineering, general background information to apply to solving problems in society, early school readiness skills for developing an inquiry focus, exposure to role models and innovators, and other privileged access to exploring the world at large.

Previous studies have shown the inhibitory properties of sweeteners, such as saccharin, to CA IX. In this study, the binding of the sweetener acesulfame potassium (Ace K) is compared between CA IX and other essential carbonic anhydrases in the body.

What did the Scientists Discover?

The Society cites his outstanding achievements in photopolymer science and technology and the “Development of new advanced photoresist for microelectronics.” Ober is the Francis Bard Professor of Materials Engineering, Materials Science and Engineering, Cornell University and he and his students and post-doctoral associates have been long-time collaborators and codevelopers of techniques and technology for small-angle x-ray scattering capabilities with CHESS staff scientist Detlef Smilgies.

To minimize the shut down (“dark”) time, we are placing all new magnets on girders. Then, when CESR operation is stopped for the upgrade, the girders will be moved to the tunnel and fitted into the storage ring. Each of the twelve girders contains two horizontal focusing quadrupole magnets, one large combined function magnet (bends the beam trajectory and focuses the beam vertically), and four small correcting magnets.

Ulrich Wiesner, the Spencer T. Olin Professor of Engineering, led the group, which included researchers in engineering, chemistry and physics.

The group’s findings are detailed in a paper published in Science Advances, Jan. 29.

But these batteries are not in common use today because, when recharged, they spontaneously grow treelike bumps called dendrites on the surface of the negative electrode.

Over many hours of operation, these dendrites grow to span the space between the negative and positive electrode, causing short-circuiting and a potential safety hazard.

A new device at the Department of Energy’s SLAC National Accelerator Laboratory allows researchers to explore the properties and dynamics of molecules with circularly polarized, or spiraling, light.

The technology – based on a covalent organic framework (COF) infused with an electronically conducting polymer thin film – could benefit numerous technologies including automotive, by speeding up the charging process, extending single-charge range and even incorporating the device into the body of the car itself.
