Platinum Opinion Optimizing Active Surveillance

Electronic metal-support interaction enhanced oxygen reduction activity and stability of boron carbide supported platinum

Catalysing the reduction of oxygen in acidic media is a standing challenge. Although activity of platinum, the most active metal, can be substantially improved by alloying, alloy stability remains a concern. Here we report that platinum nanoparticles supported on graphite-rich boron carbide show a 50-100% increase in activity in acidic media and improved cycle stability compared to commercial c...

Optimal Operation of a DWC by Self-Optimizing Control: Active Vapor Split Approach

Dividing Wall Column(DWC) offers the large potential for operating and capital cost saving in compared with conventional distillation sequence. In the studied DWC in this study, the aid of Vmin diagrams, it is shown that without a suitable value for vapor split fraction bellow the dividing wall in different operating conditions, the energy requirement increases from optimal value and it wil...

20 years of medical surveillance on exposure to allergenic and non-allergenic platinum compounds: the importance of chemical speciation.

OBJECTIVES Chloroplatinates are potent allergens but other soluble platinum compounds such as tetraammine platinum dichloride (TPC) do not provoke reactions in subjects who are sensitive to chloroplatinates. TPC has been used in the manufacture of autocatalysts for 20 years. This study analyses 20 year data on exposure to soluble platinum compounds and medical surveillance to confirm that TPC i...

Management of intermediate-risk prostate cancer with active surveillance: never or sometimes?

PURPOSE OF REVIEW Active surveillance has become the recommended management strategy for most patients with low-risk prostate cancer (PCa), but whether surveillance criteria can be expanded without compromising oncologic outcomes is a matter of debate. Whereas there is essentially uniform consensus that those with low-risk disease can be safely managed with AS, those with intermediate-risk dise...
