The dosimetric phosphors Li3PO4：M（M=Tb, Cu） were produced by modified solid-state *** structural and morphological characterization was carried out through X-ray diffraction（XRD） and scanning electron microscope（SEM）. Additionally, the photoluminescence（PL）, thermoluminescence（TL） and optically stimulated luminescence（OSL） properties of powder Li3PO4 doped with Tb and Cu were studied. It is advocated that Li3PO4： Cu phosphor not only shows higher OSL sensitivity（25 times or more） but also gives faster decay in OSL signals than that of Li3PO4： Tb^（3＋） phosphor. The minimum detectable dose（MDD） of Li3PO4：M（M=Tb,Cu） phosphors is found to be 21.69 × 10^（-3） and 3.33 ×10^（-6） J·kg^（-1）,respectively. In OSL mode, phosphor shows linear dose response in the range of 0.02-20.00 J·kg^（-1）.In TL mode, sensitivity of Li3PO4： Cu phosphor is more than that of Li3PO4： Tb phosphor. The kinetics parameters such as activation energy and frequency factors were determined by peak shape method, and photoionization cross sections of prepared phosphor were calculated.

Simultaneous Waste Water Purification via Photocatalysis and Seed Germination

引用

Green and Sustainable Chemistry 2013年第3期3卷 129-133页

Preliminary results of our study related to simultaneous waste water purification by photocatalytic degradation of organic impurity (Methylene Blue dye) and its effects on seed germination are presented here. It is interesting and important to know that complete degradation of the dye occurs within 2 hours and does not adversely affect the seed germination process. It is concluded that waste water purification by photocatalysis and seed germination (agriculture) can be carried out simultaneously, opening a way for advanced agriculture.

DOIND： a technique for leakage reduction in nanoscale domino logic circuits

引用

Journal of Semiconductors 2016年第5期37卷 69-77页

作者： Ambika Prasad Shah Vaibhav Neema shreeniwas Daulatabad Electronics & Telecommunication Engineering Department IET-Devi Ahilya University Indore-452017 India Electrical Engineering Department Indian Institute of Technology Bombay-400076 India

A novel DOIND logic approach is proposed for domino logic, which reduces the leakage current with a minimum delay penalty. Simulation is performed at 70 nm technology node with supply voltage 1V for domino logic and DOIND logic based AND, OR, XOR and Half Adder circuits using the tanner EDA tool. Simulation results show that the proposed DOIND approach decreases the average leakage current by 68.83%, 66.6%, 77.86% and 74.34% for 2 input AND, OR, XOR and Half Adder respectively. The proposed approach also has 47.76% improvement in PDAP for the buffer circuit as compared to domino logic.
