We have shown that the morphological features of the sol–gel derived thin films of ZnO depend strongly on the choice of the precursor materials. In particular, we have used zinc nitrate and zinc acetate as the precursor materials. While the films using zinc acetate showed a smoother topography, those prepared by using zinc nitrate exhibited dendritic(More)
OBJECTIVES Hypertension is one of the major cardiovascular diseases. It affects nearly 1.56 billion people worldwide. The present study is about a particular genetic polymorphism (A1166C), gene expression and protein expression of the angiotensin II type I receptor (AT1R) (SNP ID: rs5186) and its association with essential hypertension in a Northern Indian(More)
 Designed and fabricated microsensors and flexible microdevice using MEMS technology for breast cancer diagnosis.  Performed electro-mechanical characterization of breast tissue using microdevices.  Studying the changes in electro-mechanical properties of breast tissue core with progression of cancer. The work done till now has resulted in a provisional(More)
In the present work, we report the preparation of PLZT thin films in pure perovskite phase by RF magnetron sputtering without external substrate heating and their integration with micro-cantilevers. The 'lift-off' process for pat-terning different layers of a micro-cantilever including PLZT, Pt/Ti and Au/Cr was employed. The basic requirement of lift-off(More)
This paper reports the design of a Ka-band Equilateral triangular patch antenna (ETPA) fabricated using post-CMOS and post-MMIC compatible process technology. The antenna uses an air-cavity underneath the patch radiator that is supported on thin dielectric membrane. The antenna structure was analysed and optimised using the finite element method (FEM) based(More)
