For example, while inorganic forms of arsenic (e.g, As3+ and As5+) are known to be highly toxic agents, arsenobetaine (AsB) and arsenocholine (AsC) are relatively non-toxic, organoarsenic species that are considered benign. Both AsB and AsC are absorbed into the blood compartment and excreted unchanged in urine.
The program has matured over the last two years to the point where we are now commercializing the production of small, inexpensive, novel undulators and planning to upgrade as many CHESS beamlines as possible with more brilliant sources.
His current position at CHESS is "project scientist." Peter has played a key role in designing a new type of x-ray monochromator that provides uniquely flexible capabilities to focus high photon energy (40-100keV) beams to feed the F2 station. We've highlighted the new hardware capabilities previously [1].
NanoDays Schedule
A range of exciting NanoDays programs will demonstrate the special and unexpected properties found at the super tiny nanoscale; examine tools used by nanoscientists; showcase nano materials with spectacular promise; and invite discussion of technology and society.
Nanomaterials are extremely small objects (a nanometer is a billionth of a meter!). Synchrotrons are complex, giant machines, often covering an area the size of a football field. Frequently, however, these two worlds collide in an effort to understand the unusual properties that nanomaterials exhibit over their “bulk” counterparts. Dr. Ward will share stories of scientific collaboration—how scientists work together in order to apply Big Science to tackle Small Problems.

ADC Inc., a maker of scientific instruments located just outside Ithaca, has licensed the high-pressure cryocooler, called HPC-201, and has just fulfilled its first order to a research center in Japan.
The licensing agreement is ADC’s first with Cornell. Company president Alex Deyhim says the product is garnering interest from potential buyers, and he’s thrilled to showcase the “amazing work” of Cornell scientists.
Perhaps the most conspicuous change is a reorganization of the user space (Figure 1), primarily to improve access and usability of the G2 and G3 areas, especially for large groups. Among the changes are the creation of a "G3 annex" space opposite the G3 hutch to store, maintain and prepare heavy equipment, such as UHV chambers, for in situ experiments. This space occupies Arthur Woll’s former office, which has been relocated to room 316 Wilson Lab.
Visiting students representing the next generation of physicists got a taste of life as a r
The work was carried out by CHESS operators Chris Whiting, John Conrad, and Engineer Tom Krawczyk with supervision by Operations Manager Chris Conolly & Vacuum Group Leader Bob Seeley, responding to a request by Scientist Ken Finkelstein.
