Nitric oxide is a pollutant linked to the production of smog and acid rain in the environment. Due to the increase in production of nitric oxide, scientists have attempted to increase methods to detect the pollutant at low and high concentrations. Scientists have investigated gas sensors because of their low cost, sensitivity to gases at low concentrations, and fast response time. WO3 gas sensi...
Global solar radiation (Rs) has wide applications in several disciplines. The data of measured or predicted Rs are widely applied by solar engineers, architects, agriculturists and hydrologists. Due to the importance of Rs, several empirical models have been developed to predict its values all over the world. In this study, Angstrom model was calibrated based on the ratio of actual and possible...

Backscatter SEM imaging and small-angle neutron scattering (SANS) data are combined within a statistical framework to quantify the microstructure of a porous solid in terms of a continuous pore-size distribution spanning over five orders of magnitude of length scale, from 10 A to 500 microm. The method is demonstrated on a sample of natural sandstone and the results are tested against mercury p...
