Biomass conversion to alcohols using supercritical methanol depolymerization and hydrodeoxygenation (SCM-DHO) with CuMgAl mixed metal oxide is a promising process for biofuel production. We demonstrate how maple wood can be converted at high weight l

Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has been used to assign elemental formulas to tens of thousands of ions generated from petroleum samples. While elemental formulas can give insights on hydrogen deficiency or het
