    • Studies on absorption from mammalian intestine 

      Wood, Helen Ogilvie (University of St Andrews, 1945-02) - Thesis

    • Photo-conduction in semi-conductors 

      Caldwell, John Bell (University of St Andrews, 1948-04) - Thesis
      This thesis is largely concerned with the phenomenon of photo-conduction in micro-crystalline layers of lead sulphide, antimony sulphide and thallium sulphide. All the materials studied are semi-conductors, either excess ...

    • Experiments in connection with the structure of emetine 

      Norcross, Geoffrey (University of St Andrews, 1949-01) - Thesis
      Emetine is the principal alkaloid of ipecacuanha root which is obtained from the plant known botanically as Psychotria Ipecacuanha, also called Cephaelis Ipecacuanha, indigenous to Brazil, and from Psychotria Acuminata ...

    • Researches into the structure of emetine 

      Battersby, Alan Rushton (University of St Andrews, 1949-04) - Thesis
      The first crude preparation of the alkaloid emetine was obtained in 1817 by Pelletier from the plant species Cephaelis ipecacuanha. Since that day many workers have turned their attentions to the structural problem presented ...
