Large-band-gap semiconductors are the most suitable photocatalysts for CO2 reduction, because they provide sufficient negative and positive redox potentials in conductance bands and valence bands, respectively. Presently, the energy conversion efficiency is still low, mainly due to the following re ...

Ultrasonics - Mitra.ac.in
... The word ultrasonic combines the Latin roots ultra, meaning ‘beyond’ and sonic, or sound. The sound waves having frequencies above the audible range i.e. above 20000Hz are called ultrasonic waves. Generally these waves are called as high frequency waves. The field of ultrasonics have applications fo ...

Protein sorption on soft contact lenses: a comparison between
... The amount of deposits increases with the hours of wear, mainly between 4 and 24 hours for hydrogel materials. On the contrary, silicone-hydrogel lenses have a reduced affinity with proteins and, in some cases, no differences have been detected between those used for 4 hours and 3 weeks. Protein sor ...

Input Impedance, VSWR and Return Loss of a Conformal Microstrip
... microstrip antennas on cylindrical surface. In this approach, the field in terms of surface current is calculated, while considering dielectric layer around the cylindrical body. The assumption is only valid if radiation is smaller than stored energy[11]. Kwai et al. [12]gave a brief analysis of a t ...
