Nanofibers are formed using electrospray deposition from microfluidic source. The rolling member rotatably is mounted on the supporting platform. The porous materials can be used as heterogeneous catalysts. Additionally, a controller may control at least the transport apparatus. The method includes receiving the record of seismic traces in a time-offset domain, transforming the record of seismic traces to a tau-p domain, applying a zero offset inverse Q algorithm to the record of seismic traces in the tau-p domain, and transforming the record of seismic traces back to the time-offset domain.
