World's smallest diamond anvil cell
The research work published in the August issue of Nano Letters report the development of the world’s smallest anvil pressure cell, which offers a new experimental platform for investigating the elastic behavior of molecular bundles embedded at nanocrystal interfaces of nanocomposites.
Supercrystals of nanocrystals bound by organic ligands
Modern crystallography can be tracked back to Max Laue who conceived the first diffraction of x-ray by a crystal lattice in 1913. Upon public release of the Laue pattern collected from several crystals, Albert Einstein immediately labeled this work as one of the most beautiful experiments in physics.
Coates, McLafferty win national chemistry awards
Cornell faculty members Geoffrey Coates and Fred McLafferty have received national American Chemical Society (ACS) awards. Both receiving $5,000 prizes, they will be honored at a March 24 ceremony during the ACS meeting in Denver.
Group invents materials to improve particle accelerators
Physics graduate student Siddharth Karkare is the first author on a recent Physical Review Letters publication reporting new interdisciplinary research on "Ultrabright and Ultrafast III-V Semiconductor Photocathodes" that could dramatically improve accelerator performance (1).
New high energy beamline as state-of-the-art grain mapping facility
High-energy (HE) x-ray diffraction (energies 30 keV and above) have long been a mainstay at CHESS, supporting many user groups on a wide variety of in-house developed techniques.
Proteins at work inside a membrane
Proteases, enzymes that cleave proteins, are found both free-floating and embedded in membranes. Reactions involving the former are well understood, but the workings of the latter have remained mysterious – how are reactions controlled inside the viscous, two-dimensional membrane, from which water is excluded?
Unwrapping DNA from nucleosomes
DNA in the cell must be stored in a compact form (or it wouldn't fit) that also allows it to be translated to RNA, and to be copied when a cell divides.
Electrostatic interactions help an enzyme do its job
A catalytic enzyme facilitates a reaction by bringing one or more molecules into its active site and there providing an environment conducive to the reaction.
