In this paper, we present a process for growing a Cu seed layer on a Ta/SiO 2 /Si substrate using an electroless plating (ELP) process at an extremely low temperature (∼30°C). In this process, the activation treatment of the Ta/SiO 2 /Si substrate was carried out by immersion in a PdCl 2 /HCl solution prior to electro…

In this paper we demonstrate for the first time that pre-vulcanized NR latex can be doped by iodine to become electrically conducting. The study reveals that pre-vulcanisation will not hinder the formation of conjugated sequences, which is widely accepted as a prerequisite for developing intrinsic electrical conductiv…

La 1− x Li x FeO 3 solid solution prepared by solid-phase synthesis in an air environment at atmospheric pressure is found to exist only for x ≲0.1. All single-phase samples are p -type semiconductors. An increase in lithium concentration brings about a decrease in their electrical resistivity and thermopower. The res…

Polarization hysteresis loop of CaBi4Ti4O14 thin film has been studied in the frequency range from 200 Hz to 600 KHz for different applied voltages. It shows that the hysteresis loop is frequency- and voltage-dependent. The maximum polarization decreases logarithmically with the increase of frequency. In contrast, the…

In earlier days it was believed that the presence of microbes at a slightly higher density (i.e 10^4 CFU) showed that the environment was corrosive. In the year 1995 researchers identified that there are certain groups of microorganisms which can offer protection to the materials. The majority of the research work con…
