Fractional Fourier transform as a signal processing tool: An overview of recent developments

Polonium-210 and lead-210 in the terrestrial environment: a historical review.

Thank you for reading carbon nanotubes synthesis structure properties and applications. Maybe you have knowledge that, people have search hundreds times for their favorite readings like this carbon nanotubes synthesis structure properties and applications, but end up in infectious downloads. Rather than reading a good book with a cup of tea in the afternoon, instead they are facing with some infectious virus inside their laptop.

Microfluidic paper-based analytical devices (μPADs) have garnered significant interest as a promising analytical platform in the past decade. Compared with traditional microfluidics, μPADs present unique advantages, such as easy fabrication using established patterning methods, economical cost, ability to drive and manipulate flow without equipment, and capability of storing reagents for various applications. This Review aims to provide a comprehensive review of the field, highlighting fabrication methods available to date with their respective advantages and drawbacks, device designs and modifications to accommodate different assay needs, detection strategies, and the growing applications of μPADs. Finally, we discuss how the field needs to continue moving forward to realize its full potential.

Microfluidic Paper-Based Analytical Devices: From Design to Applications.

Studies on radiation level and radionuclide distribution in the region of Coastal Karnataka, India, were undertaken. The purpose of this study is to provide baseline data on radiation level and radionuclide distribution in the region for the future assessment of the impact of the nuclear and thermal power stations that are being set up in the region. Further, this study may reveal information on the transportation of radionuclides in the environment. The external gamma dose rates in air have been measured throughout Coastal Karnataka using a sensitive plastic scintillometer. The measured dose rates include both terrestrial and cosmic ray components. The gamma dose rates in air range from 26 to 174 nGy h(-1) with a median value of 74 nGy h(-1). The activities of naturally occurring radionuclides in the soil samples of the region were measured using HPGe gamma ray spectrometry, and the resulting doses in air were calculated. The activity of 40K varies from 61.0 to 316.7 Bq kg(-1) with a median of 117.5 Bq kg(-1); the activity of 226Ra varies from 20.1 to 62.3 Bq kg(-1) with a median value 35.0 Bq kg(-1) and that of 232Th from 14.3 to 48.6 Bq kg(-1) with a median value of 29.8 Bq kg(-1). The mean absorbed dose rate in air due to naturally occurring radionuclides is found to be 41.5 nGy h(-1). In addition to this, the correlations between 226Ra and 40K, 232Th and 40K, and 226Ra and 232Th were computed from the results of the concentration of these naturally occurring radionuclides. A weak correlation was observed between 226Ra and 40K and between 232Th and 40K while a moderately good correlation was observed between 226Ra and 232Th. The results of these systematic investigations are presented and discussed in this paper.

Materials exhibit fascinating properties when one or more of their dimensions is reduced to the nanometer scale. One of the most immediate observations when reducing the size of materials to the nanometer scale is the confinement in the movement of electrons due to the quantum confinement effect. This leads to discretization of electron energy levels depending on the confinement size of the material. The resulting structure exhibits interesting novel optoelectronic, physicochemical, mechanical, and magnetic properties not shown by the corresponding bulk structures of the same material. This chapter presents insights on quantum nanostructures, which are classified according to their degrees of quantization, especially quantum dots (QDs). Further, the special properties exhibited by zero-dimensional structures, such as photoluminescence, multiple exciton generation, and size tunable bandgap, are discussed. This chapter also introduces various synthesis and fabrication processes used to fabricate QDs in exclusive applications, such as displays, biological labels, and photovoltaics.
