Is it possible to detect Aspirin molecules using SERS on Au/TiO2/WO3 substrates?

I have managed to obtain Raman spectra for Aspirin by using the 785 nm laser line, but I have difficulties obtaining a SERS spectrum for Aspirin on the Au/TiO2/WO3 substrates. The following...

In the case of methyl orande degradation modelling with WO3-TiO2 composites which mechanism do you think fits best?

We have studied the effect of the catalyst load, initial concentration and light intensity upon the MO degradation with WO3-P25 composite systems. We have tried the LH mechanism and attributed...
