  • Misconceptions in Chemistry
    Students have problems switching from the level of substances to the level of particles and they like – even in advanced classes – to stay on the level of substances: ‘‘hydrogen chloride plus acid gives hydrochloric acid’’.
  • Biotechnology for Biofuels | Full text | Evaluation of preservation methods for improving biogas production and enzymatic conversion yields of annual crops
    Dilute sulfuric or hydrochloric acids , as well as organic acids, are commonly used for pretreatment of various raw materials prior to enzymatic hydrolysis [8], but usually in significantly more severe conditions than those applicable for ensiling. Sulfuric acid treatment prior to anaerobic ensiling was found to enhance the conversion of reed canary grass and switch grass to ethanol [9], indicating that lower levels of acid amendments to ensilage can have the desired effects.
