| Chemat Technology Awarded SBIR Phase II Grant For High Frequency Ultrasonic Transducer for Medical Imaging By National Science Foundation |
|---|
| August 19, 2010 |
|---|
Chemat Technology Inc. was awarded a Small Business Innovation Research (SBIR) Phase II grant from the National Science
Foundation (NSF). Under this Phase II Chemat will develop a piezoelectric element with a thickness of 1/10 of human hair and a high frequency
frequency linear array will be fabricated with this piezoelectric element. This new effort follows Chemat's successful execution of a Phase I
study effort during 2009.
Low frequency ultrasound is a well-established imaging modality that currently accounts for about 1/3 of all diagnostic imaging procedures.
The world market for diagnostic ultrasound in 2008 was $5.37B. The U.S. market, in 2008, totaled $1.59B—approximately 1/3 of the world market.
Over the years the image resolution offered by ultrasound has continued to improve. In ultrasound, spatial resolution is determined by the
frequency and degree of focusing. Advances have been made to allow ultrasound systems to offer better image quality and temporal
resolution for real-time imaging.
High-frequency ultrasonic imaging (HFUI) is a new frontier in diagnostic ultrasound that has been used as a diagnostic as well as surgical
tool in ophthalmology, dermatology, superficial organ imaging, intravascular ultrasound (IVUS) imaging, and small organs and small animal studies.
Due to the need for higher resolution of ultrasonic images, transducer frequency has also increased in order to yield images of cellular
structures in living tissues.
Chemat is developing miniaturer transducer for higher resolution ultrasound medical imaging by employing a sol-gel nanocomposite technology.
Miniature size is from employing high-K piezoelectric material. The high resolution is due to in part much higher working frequency.

| Chemat Received a DOE SBIR Phase I Award on Developing Li2MSiO4 Material |
|---|
| July 15, 2010 |
|---|
Chemat has recently been awarded a DOE SBIR Phase I Development Contract to develop a Li2MSiO4 nanostructured Li-ion battery cathode
material with improved conductivity for application in hybrid and electrical vehicle. Car battery requires high power and high energy densities,
due to rigorous weight and volume constraints. One way to increase the energy density and specific energy of a battery is to use an electrochemical couple
in which the active materials in one or both electrodes undergo multiple electron redox reactions. Li2MSiO4 materials have high capacity (300 mAh/g),
lattice stabilization, safety, low cost compared to LiFePO4 and LiMn2O4 with following recognized advantages:
·It is potentially cheaper – even cheaper than the phosphate derivates – with iron and silicon oxides making up > 10% of the Earth’s crust.
·It is an essentially “green” material with virtually no direct or associate environmental hazards compared to both cobalt and nickel.
·It has also been shown to compare favorably in term of its mechanical, chemically and electrochemical properties with other candidate cathodes.
It also cycles well with a minimum of capacity loss under extended cycling.
Chemat is seeking an industrial partner for implementing advanced nanostructured cathode material in Li-ion batteries.

| Sol-gel Technology to improve antibacterial function of Cotton |
|---|
| June 4, 2010 |
|---|
In recent review paper published in Journal of Sol-gel Science and Technology by Dr. Wang, Key Laboratory of Eco-Textile, Jiangnan University,
China has discussed how to use sol-gel as a carrier of antibacterial moiety to attach on cotton surface. A unique property of the sol-gel process is the
ability to convert molecular precursors to a film product. Complex silane precursors consisting of hydrophobic groups and antibacterial active agent
such as quaternary ammonium salt moieties seem to be a much better option because their multifunctional chemical character, such as antibacterial property
and hydrophobicity, the latter important for controlling the release of the active component to the surroundings.
Research showed that antibacterial effect decreased with washing. However, after 10 times of washing, about 60% of antibacterial function still maintained.
Other textile properties were also studied. The breaking strength of treated cotton was slightly increased in warp and weft directions. The whiteness
was decreased about 20%. The hand feeling of the treated cotton was decreased. Besides quaternary ammoniu salt moieties, many other antibacterial moieties
were reported such as precious metal ions, amino acid sequence of SEQ ID NO: 1, polyoxometalates, chlorinated halamines.

| Coatings made by sol–gel and chemical nanotechnology |
|---|
| May 10, 2010 |
|---|
Today the sol–gel technology expands rapidly and many new products are appearing on the market, especially since the advent of hybrid
and nanocomposite materials, the so-called Ormocer and Nanomer systems. Most of the products are coatings which are developed to exhibit several functional
properties using precursor solutions and easy and fast processing. The low temperature post-processing by UV irradiation or heat treatment made on-line after
the deposition process using available industrial technologies and the combination of the best properties obtained with inorganic and polymeric systems are
further advantages. Although most of the glasses can withstand high temperature post-treatment, low temperature processing saves large amount of time and energy
and is today mandatory for preformed products.
A feature article on industrial application sol-gel coating was published in Journal of Sol-Gel Science and Technology, volume 47, page 203 to 236 in 2008.
The paper listed variety of coatings used in Automotive, architectural, Ophthalmic, Electronic industries and Household.

| Chemat has been awarded a DOD SBIR Phase I Development Contract to develop a Li-ion battery cathode material suitable for space applications. |
|---|
| April 10, 2010 |
|---|
Chemat has recently been awarded a DOD SBIR Phase I Development Contract to develop a nanostructured advanced Li-ion battery cathode material for space application.
Communications satellites deployed in geosynchronous earth orbit have an operational lifetime of 10 to 15 years. This requires secondary batteries capable of providing up to 60,000 charge/discharge cycles. Even using state of the art cathode materials, current Li-ion batteries have a limited life and the aim of the development contract is to use a nanostructure material to enhance battery life.
This research will be carried out by Chemat in collaboration with Prof. Shirley Meng of the University of California. Dr. Meng focuses her research on the direct integration of experimental techniques using computation modeling to develop new materials for electric energy storage. Her research interests include oxides and phosphates and their electrochemical and thermoelectric applications, in particular, the processing – structure – property relationship of functional nanomaterials and the size-dependent thermodynamic and transport properties of materials at the nano-scale.
