N-acylation and O-acylation of pseudoephedrine are studied by using aroyl chlorides and/or ethyl chloroformate as acylating agents. Thus, treatment of pseudoephedrine or its salt with benzoyl or p-nitrobenzoyl chlorides affords the corresponding N- o

We studied the multiferroic property of Ca 1-x La x Ti 1-x Fe x O 3 (0.0 ≤ x ≤ 0.5) perovskite. We showed that multiferroic property can be triggered by strain mediation due to different ion doping. The prepared samples were characterized by X-ra
