This month the patent summaries have been made even briefer than they were before, in an effort to catch up most of the backlog of recently pubfished US and WO patents. It is encouraging that there is clearly so much research and development work going on in this very active area. We expect to return to more detailed summaries once most of the bacHog has been summarised. Hopefully the essential features of these new inventions are clear enough, even in this abbreviated form.

Perovskite-type oxide LaFeO 3 powder was prepared using a stearic acid combustion method. Its phase structure, electrochemical properties and hydrogen storage mechanism as negative electrodes for nickel/metal hydride (Ni/MH) batteries have been investigated systematically. The results of X-ray diffr
## Abstract Background The effect of the B cation on the surface properties and catalytic activity in the total combustion of toluene over La~1βx~Ca~x~BO~3~ (B = Fe,Ni) perovskiteβtype oxides was studied. Result For the La~1βx~Ca~x~FeO~3~ series, the perovskite structure was maintained in the rang
