A CoAPO-34 derived from a triclinic precursor prepared in the presence of HF
(Elsevier Science Inc., 1997)
The fluoride route of synthesis of AIPO,-34 is also successful in the preparation of its cobalt modified product (CoAPO-34). The triclinic precursor of CoAPO-34 has been synthesized in the presence of HF and piperidine. ...
Preparation of Two Cobalt-Substituted Zincophosphate Molecular Sieves
(Marcel Dekker, Inc., 1997)
Two different open-framework cobalt-zincophosphate phases crystallise from the same reaction mixture at ambient conditions depending on the preparative procedure. One of them is a sodalite analogue containing up 70 8 wt.% ...
HREM observations of mechanical twinning in Cu-Ti alloys: Structure of incoherent and coherent twin interfaces
(Minerals, Metals & Materials Soc (TMS), 1997)
The flow of Cu-Ti alloys hardened by coherent β′ precipitates (Cu4Ti, D1a superstructure) is particularly interesting since these alloys show profuse twinning on multiple systems after small amounts of plastic flow by slip. ...
