Although bacterial oxidation of sulfide materials results in the undesirable formation of acid mine drainage, the same reaction has been put to use for microbial leaching of copper, uranium, and other valuable metals from low-grade sulfide-containing ores.
and that the treatment does not cause any undesirable formation damage by uncontrolled fracture growth and/or multiple secondary fracture initiation.
The undesirable formation and low-efficient decomposition of Li2CO3 on cathode of Li-air battery, is an insurmountable obstacle for its practical applications.
The catalytic oxidation of aqueous phenol over MnO2/CeO2 mixed oxide catalyst was shown to be accompanied with undesirable formation of heavy polymers on the catalyst surface leading thereby to its deactivation.
Comparative studies for the aluminosilicates and the well-known sulfonic acid resin Amberlyst™-15 were reported on the basis of EL yields, the undesirable formation of diethyl ether, and catalyst stability (regeneration and reuse).
Reduced graphene oxide (rGO) tethered with maghemite (γ-Fe2O3) was synthesized using a novel modified sol gel process, where sodium dodecylbenzenesulfonate was introduced into the suspension to prevent the undesirable formation of an iron oxide 3D network.
