SYRACUSE, N.Y. - State Sen. John DeFrancisco is upset that Gov. Andrew Cuomo is excluding state lawmakers from multi-million dollar economic development decisions, like the new nanotechnology hub in DeWitt.
DeFrancisco learned Tuesday afternoon that Cuomo was headed to Syracuse to announce the new nanotechnology facility in the senator's district.
Before that phone call from the governor's office, DeFrancisco had no clue the state had picked a developer, a site and a tenant for the Central New York Hub for Emerging Nano Industries.
DeFrancisco said he's not upset about the new hub and the jobs it could bring. "It may be a phenomenal thing," he said.
The Legislature approved overall economic development funding in a past budget, but doesn't get to vote on this specific project.
DeFrancisco said he's not going to drop his criticism of the state's film tax credits, a program that awards $420 million annually to one industry and stands to benefit the hub's first tenant, The Film House, a movie production studio.
Instead, DeFrancisco is pushing for language in this year's budget that would require the governor have to disclose more information about specific economic development projects throughout the state.
"I just think the pendulum's gone too far with gubernatorial control," DeFrancisco said. "Maybe it was too far the other way with the Legislature having too much say. I don't know. But it just seems right now one person should not be able to make same-day announcements of projects that affect the constituents of the legislators in that area."
The governor's office did not respond to questions Friday afternoon about DeFrancisco's comments.
State lawmakers at one time did have more control over economic development funds. They handed out millions of dollars in "member items" to local organizations, legislative pork that drew criticism for lack of transparency and fairness. Then-Gov. David Paterson vetoed hundreds of member items in 2010, essentially stopping the funding streams.

Diasome Pharmaceuticals, Inc. (http://www.diasome.com) has received notice from its licensor, SDG, Inc., that SDG has received a notice of allowance for its novel weight loss nanotechnology patent application. This patent, entitled Orally Bioavailable Lipid Constructs, covers composition of matter claims related to the use of the Companys proprietary oral Hepatocyte Directed Vesicles (HDV) as a weight loss compound. HDV is a 20-50 nanometer drug delivery system that is designed to target drugs and nutraceuticals to hepatocytes, the livers metabolic cells.
Diasome Pharmaceuticals has received a worldwide, exclusive license to this technology from SDG, along with technology rights to SDGs platform of hepatic (liver) targeted injectable and oral therapies for diabetes and obesity. Diasomes technologies have received more than $40 million in research and development funding over their history, and the Company has multiple Phase-2 stage human clinical candidates for metabolic conditions in its pipeline.
We are very pleased with the notice of allowance for this novel weight loss technology, said Robert Geho, Diasomes Chief Executive Officer. The HDV system for weight loss can be manufactured for everything from oral capsules to additives to food and beverage products. Being able to move forward with this level of patent protection is very important to our development and commercial strategy.
About Diasome Pharmaceuticals, Inc.
Diasome Pharmaceuticals, Inc. is focused on the clinical and commercial development of breakthrough therapies for diabetes and obesity. Based on more than thirty years of research and development in the fields of cell receptor targeting, insulin replacement, and hepatic (liver) glucose metabolism, the Companys pipeline includes multiple injected and oral formulations of liver targeted insulins for both Type 1 and Type 2 diabetic patients that are Phase 3 ready. In addition, Diasome is developing a first-in-class oral compound for the Type 2 diabetes population that is based upon new insights into normal glucose metabolism and a novel mechanism of action, along with a nanotechnology-based oral compound that may have a significant impact in treating obesity.
Diasomes technology platform is based on the use of its proprietary Hepatocyte Directed Vesicle, or HDV, nanotechnology to deliver a wide range of critically necessary hormones and drugs to the liver, the bodys primary site of glucose storage. It is generally recognized by diabetologists that the currently available forms of injected insulin used by all Type 1 diabetic patients and a significant percentage of people with Type 2 diabetes do not function in the body in the same way as naturally produced insulin. Because insulin tells the body when and how to store glucose, the ideal insulin therapy would function as closely to normal insulin as possible. Diasomes HDV system is designed to fundamentally improve the way in which insulin works in people with diabetes by, for the first time, enabling much greater amounts of injected insulin to reach hepatocytes, the livers glucose storing cells.

(Phys.org) Over the past half-century, biosensors have opened a new window on the physical world while revolutionizing much of modern society.
By utilizing an electronic or optical system, biosensors detect and interact with the components of biological materials, making it possible to analyze DNA, measure the content of glucose in the blood, detect biotoxins in the water and the atmosphere and much more.
Sales of biosensors reached $8.5 billion worldwide in 2012 and are expected to double to $16.8 by 2018. The United States, with $2.6 billion in sales in 2012, leads the world market.
Yongkang Gao has spent much of the past three years using nanotechnology to improve the speed, efficiency and sensitivity of biosensors while dramatically decreasing their size and cost of operation.
His goal is to transform today's relatively bulky surface plasmon resonance (SPR) biosensors, which take up most of a desktop, into nanoplasmonic biosensors that can be held in the hand and can perform hundreds of testsmedical, environmental or otherat a time.
Gao, who completed his Ph.D. in electrical engineering in January and is now a researcher with Bell labs in New Jersey, is the lead author on an article that a team of Lehigh engineering researchers published recently in the journal Lab on a Chip. The group also contributed the cover image for the issue.
Titled "Plasmonic interferometric sensor arrays for high-performance label-free biomolecular detection," the article was coauthored with Zheming Xin, Beibei Zeng, Qiaoqiang Gan, Xuanhong Cheng and Filbert J. Bartoli. Xin and Zeng are Ph.D. candidates. Gan, who earned his Ph.D. from Lehigh in 2010, is an assistant professor of electrical engineering at the State University of New York at Buffalo. Bartoli, the Chandler Weaver Endowed Chair of Electrical and Computer Engineering, is Gao's Ph.D. adviser and leads the project. Cheng, the P.C. Rossin Assistant Professor in the department of materials science and engineering, is director of Lehigh's Lab of Micro- and Nanotechnology for Diagnostics and Biology.
Improving on the "gold standard"
Scientists have made great progress in recent decades with labeled biosensors that use a receptor attached to a fluorescent molecule to target biomolecules. When bonding occurs between the target and receptor molecules, the fluorescent label emits a light signal whose color provides information about the identities of the two molecules that are bonding and the strength of the bond.

Salina, N.Y. A proposed nanotechnology facility in Salina that remains vacant 3 1/2 years after it was announced will eventually open despite a new project in the field announced yesterday for DeWitt.
New York said in 2010 it would invest $28 million to transform a former General Electric lab at the park into a facility that will employ up to 250 people.
Those plans haven't changed, said Alain Kaloyeros, CEO of the SUNY College of Nanoscale Science and Engineering in Albany. The focus will be on defense-related work involving nanotechnology, the science of manipulating individual atoms and molecules.
The Nanoscale College is involved in the Electronics Park facility and the new project Gov. Andrew Cuomo announced Tuesday at Onondaga County Executive Joanie Mahoney's State of the County address.
Cuomo said the state will spend $15 million to create a nanotech hub at the Collamer Crossings Business Park that will eventually employ 350 people. Its first tenant will be the Film House, a film production company.
The Electronics Park facility should be up and running in 2014, Kaloyeros said.
The building was neglected over the years, which meant it needed major rehab, said Kevin Schwab, a spokesman for CenterState CEO, which manages Electronics Park.
"That process is complete now," he said. "We are ready for construction and development."
Schwab said the governor's announcement of the DeWitt hub shouldn't hurt the Electronics Park site.
"Nanotechnology is a platform that can be applied across a wide range of industries and I think that's what you're seeing here," he said.

DEWITT, N.Y. - If you're looking to blow something up for a major Hollywood blockbuster these days, you might need a dose of science.
Some of the materials used to contain those explosions, and ensure they only blow up the things they're supposed to, are based on nanotechnology.
That's the science of manipulating individual atoms and molecules, said Alain Kaloyeros, CEO of the SUNY College of Nanoscale Science and Engineering.
Those materials and other innovations will take center stage at a new nanotech-focused hub planned for Collamer Crossings Business Park in DeWitt. Gov. Andrew Cuomo announced the project Tuesday.
Other nanotechnology-related advances that could come into play in the movie business include:
The DeWitt hub's first tenant is a film production company called The Film House that will make use of nano-powered moviemaking technology.
The Film House will focus on making movies. Other companies that populate the facility will concentrate on research and development of new technologies, Kaloyeros said.
In addition to the film industry, the hub will try to attract tenants in energy and the medical device sector.
The site will employ 350 people, according to Cuomo. The Nanoscale College will own and manage the facility.
Nanotechnology allows researchers to design new materials from the ground up and imbue them with specific characteristics by altering them at the atomic level, Kaloyeros said.

There's an unprecedented multidisciplinary convergence of scientists dedicated to the study of a world so small, we can't see it -- even with a light microscope. That world is the field of nanotechnology, the realm of atoms and nanostructures. Nanotechnology is so new, no one is really sure what will come of it. Even so, predictions range from the ability to reproduce things like diamonds and food to the world being devoured by self-replicating nanorobots.
In order to understand the unusual world of nanotechnology, we need to get an idea of the units of measure involved. A centimeter is one-hundredth of a meter, a millimeter is one-thousandth of a meter, and a micrometer is one-millionth of a meter, but all of these are still huge compared to the nanoscale. A nanometer (nm) is one-billionth of a meter, smaller than the wavelength of visible light and a hundred-thousandth the width of a human hair [source: Berkeley Lab].
As small as a nanometer is, it's still large compared to the atomic scale. An atom has a diameter of about 0.1 nm. An atom's nucleus is much smaller -- about 0.00001 nm. Atoms are the building blocks for all matter in our universe. You and everything around you are made of atoms. Nature has perfected the science of manufacturing matter molecularly. For instance, our bodies are assembled in a specific manner from millions of living cells. Cells are nature's nanomachines. At the atomic scale, elements are at their most basic level. On the nanoscale, we can potentially put these atoms together to make almost anything.
In a lecture called "Small Wonders:The World of Nanoscience," Nobel Prize winner Dr. Horst Strmer said that the nanoscale is more interesting than the atomic scale because the nanoscale is the first point where we can assemble something -- it's not until we start putting atoms together that we can make anything useful.
In this article, we'll learn about what nanotechnology means today and what the future of nanotechnology may hold. We'll also look at the potential risks that come with working at the nanoscale.
In the next section, we'll learn more about our world on the nanoscale.

A new twist on a very old physics technique could have a profound impact on one of the most buzzed-about aspects of nanoscience.
Researchers at the University of Cincinnati have found that their unique method of light-matter interaction analysis appears to be a good way of helping make better semiconductor nanowires.
"Semiconductor nanowires are one of the hottest topics in the nanoscience research field in the recent decade," says Yuda Wang, a UC doctoral student. "Due to the unique geometry compared to conventional bulk semiconductors, nanowires have already shown many advantageous properties, particularly in novel applications in such fields as nanoelectronics, nanophotonics, nanobiochemistry and nanoenergy."
Wang will present the team's research "Transient Rayleigh Scattering Spectroscopy Measurement of Carrier Dynamics in Zincblende and Wurtzite Indium Phosphide Nanowires" at the American Physical Society (APS) meeting to be held March 3-7 in Denver. Nearly 10,000 professionals, scholars and students will attend the APS meeting to discuss new research from industry, universities and laboratories from around the world.
Key to this research is UC's new method of Rayleigh scattering, a phenomenon first described in 1871 and the scientific explanation for why the sky is blue in the daytime and turns red at sunset. The researchers' Rayleigh scattering technique probes the band structures and electron-hole dynamics inside a single indium phosphide nanowire, allowing them to observe the response with a time resolution in the femtosecond range or one quadrillionth of a second.
"Basically, we can generate a live picture of how the electrons and holes are excited and slowly return to their original states, and the mechanism behind that can be analyzed and understood," says Wang, of UC's Department of Physics. "It's all critical in characterizing the optical or electronic properties of a semiconducting nanowire."
Semiconductors are at the center of modern electronics. Computers, TVs and cellphones have them. They're made from the crystalline form of elements that have scientifically beneficial electrical conductivity properties.

Newswise STONY BROOK, NY, March 4, 2014 The National Nanotechnology Initiative defines nanotechnology as the understanding and control of matter at the nanoscale, at dimensions of approximately 1 and 100 nanometers, where unique phenomena enable novel applications. Nanotechnology is taking the world by storm, revolutionizing the materials and devices used in many applications and products. Thats why a finding announced by Xiang-Feng Zhou and Artem R. Oganov, Group of Theoretical Crystallography in the Department of Geosciences, are so significant.
The paper,Semimetallic Two-Dimensional Boron Allotrope with Massless Dirac Fermions, was published on February 27 in Physical Review Letters. The lead author is Oganovs postdoc at Stony Brook, Xiang-Feng Zhou, who is also an Associate Professor at Nankai University in Tianjin, China.
Boron is in many ways an analog of carbon, Xiang-Feng says. Its nanostructuresnanoparticles, nanotubes, and two-dimensional structureshave attracted a lot of interest in the hopes of replicating, or even surpassing, the unique properties and diversity of carbon nanostructures. We discovered the structure of two-dimensional boron crystals, which is relevant to electronic applications and to understanding boron nanostructures. Our findings overturn the assumptions and predictions of numerous previous studies.
Earlier work had concluded that two-dimensional boron will adopt the geometry of flat alpha sheets (structures composed of triangular and hexagonal atom patterns) or their analogs. These findings were used to construct boron nanotubes and nanoparticles with unique properties, such as high mechanical strength and tunable electronic conductivity.
We found that the alpha sheet is massively unstable; this casts doubt on previous models of boron nanostructures, Oganov says. In particular, we discovered that flat monolayer structures of boron are extremely unstable, and the actual structures have finite thickness. This result will likely lead to a revision of structural models of boron nanoparticles and nanotubes. In particular, it is possible that hollow, fullerene-like structures will be unstable for boron.
Oganov says the newly discovered two-dimensional boron structure possesses properties superior to those of graphene. Within the 2D boron structure, electrons travel at speeds comparable to the speed of light, and behave as if they were massless; in some directions, the electrons travel faster than they do in graphene. This can be very advantageous for future electronic devices.
While velocity does not depend on direction in graphene, the new boron structure exhibits directional dependence. In the slowest direction, the elections travel 38% slower in boron than in graphene. But in the perpendicular direction, the elections travel 34% faster in boron. This is the property that could be of value for electronic applications.
The findings were made possible by the structure prediction code USPEX (Universal Structure Predictor: Evolutionary Xrystallography) that was developed by Oganov and his lab. USPEX weds a powerful, global optimization algorithm with quantum mechanics and is used by more than 1600 scientists around the world.

Researchers from Johannes Gutenberg University Mainz demonstrate a new principle for magnetic recording / Publication in Nature Nanotechnology The research group of Professor Jairo Sinova at the Institute of Physics at Johannes Gutenberg University Mainz (JGU), in collaboration with researchers from Prague, Cambridge, and Nottingham, have predicted and discovered a new physical phenomenon that allows to manipulate the state of a magnet by electric signals. Current technologies for writing, storing, and reading information are either charge-based or spin-based. Semiconductor flash or random access memories are prime examples among the large variety of charge-based devices. They utilize the possibility offered by semiconductors to easily electrically manipulate and detect their electronic charge states representing the "zeros" and "ones". The downside is that weak perturbations such as impurities, temperature change, or radiation can lead to uncontrolled charge redistributions and, as a consequence, to data loss. Spin-based devices operate on an entirely distinct principle. In some materials, like iron, electron spins generate magnetism and the position of the north and south pole of the magnet can be used to store the zeros and ones. This technology is behind memory applications ranging from kilobyte magnetic stripe cards to terabyte computer hard disks. Since they are based on spin, the devices are much more robust against charge perturbations. However, the drawback of current magnetic memories is that in order to reverse the north and south poles of the magnet, i.e., flip the zero to one or vice versa, the magnetic bit has to be coupled to an electro-magnet or to another permanent magnet. If instead one could flip the poles by an electric signal without involving another magnet, a new generation of memories can be envisaged combining the merits of both charge and spin-based devices.
In order the shake a magnet electrically without involving an electro-magnet or another permanent magnet one has to step out of the realm of classical physics and enter the relativistic quantum mechanics. Einsteins relativity allows electrons subject to electric current to order their spins so they become magnetic. The researchers took a permanent magnet GaMnAs and by applying an electric current inside the permanent magnet they created a new internal magnetic cloud, which was able to manipulate the surrounding permanent magnet. The work has been published in the journal Nature Nanotechnology on 2 March 2014.
