PROFESSIONAL EXPERIENCE

Silberline Manufacturing Co. Inc, Tamaqua PA Research Scientist, July 2008- Oct. 2011)

• Developed and patented a functional PVD pigment starting from conceptualization to lab scale proof of concept to roll-to-roll pilot scale level.

• Patent application filed on another functional pigment (made through solid state reaction)

• Filed DOI (Disclosure of Invention) from Conceptualization to Lab scale proof of concept of color metallic effect pigment made by using magnetron sputter unit.

• Worked with technical staff to analyze/test the draw downs, paints of the pigments tested for weather stability of adhesion, color stability and functional performance in Weather-O-Meter

• Evaluated an already existing effect pigment for thermal stability and submitted the report

• Developed mica based effect pigment through wet chemistry inorganic process.

Dept. of Chemical Engineering, Texas Tech University, Lubbock, TX, USA (Postdoctoral Fellow: May 2005- July 2008)

• Used a combination of computational chemistry techniques and in-situ atomic force microscopy (AFM) experiments to control the coarsening of an energetic material (PETN).

• Improved the stability of PETN material by Zn doping.

• Studied the effect of moisture on the fibers of sanitary products using AFM and environmental SEM and a humidity chamber

• Determined the source of swelling of fibers and provided solutions to improve the contact between individual fibrils to make the fiber surface smooth.

Dept. of Chemistry, Oklahoma State University, Stillwater, OK, USA

(Postdoctoral Fellow: May 2001- April 2005)

• Used XPS, TPD, UPS, to study the adsorption and decomposition chemistry of cyanogens halides on Si surfaces (for making CN thin films that are technologically important for chemical sensors, molecular and optical electronics).

• Made molecular cyanogens thin films (CVD) on Si surface at low temperature

• Made stable CN films on Si surfaces from room temperature up to 470K.

• Used ion-bombardment induced light emission spectroscopy to study the adsorption of Silane (SiH4) and Germane (GeH4) on Si surfaces.

• These experimental conditions simulate the processes that occur in Plasma Enhanced Chemical Vapor Deposition (PE-CVD) of Si, a-SiH and SiO2 thin films.

• Produced micro-crystalline SiH on Si surface at low beam energy and low exposure of silane

• Transformed the micro-crystalline SiH into a-SiH thin films (that has applications in the solar cells) using high beam energy and higher exposure.

• Proved that under the exposure of germane, the formation of hydrides is less than on Ge surface than on Si surface.

Fundamental Electronics Research Institute, Osaka Electro-Communication University, Neyagawa, Osaka, Japan (Postdoctoral Fellow: May 1999-March 2001)

• Used temperature variable STM, studied the atomic level control of metallic nanostructures on passivated Si surfaces.

• Controlled the Cu nano-islands (by PVD) to form on the step edges, and domain boundaries of passivated Si (111) surface at about 345C.

• Identified the top of the Cu nano-islands to have body, centered cubic -phase Cu-Si alloy
