Introduction: One of the combination therapies for the treatment of cancer is ultrasound with other agents, which has received considerable attention in recent years. Ultrasound causes cavitation phenomenon that can produce some effects, such as; Reactive Oxygen Species (ROS), which results in damage to cancer cells. When a particle is in liquid, the cavitation threshold decrea...

Several methods have been developed for gold exploration in the past, among which biological base method is known to be the most efficient with least expenses. This method can also be used for latent gold prospects exploration. In the present study, the possibility of applying Bacillus cereus frequency in soil as a biological marker was investigated for the exploration of latent gold prospectin...

In this review, we describe the papers and patents dealing with the fluorous biphasic system (FBS) hydrosilylation reactions reported to date. Despite the limited number of reports, the FBS hydrosilylation reaction has been extremely successful. In all cases fluorous monophosphines (either alkylic or perfluoroalkylsilyl-substituted derivatives of triphenylphosphine) have been employed as ligand...
