Controlled deposition of metals is essential for the creation of bimetallic catalysts having predictable composition and character. Continuous co-electroless deposition (co-ED) permits the creation of bimetallic catalysts with predictive control over composition. This method was applied to create a suite of Cu–Pt mixed-metal shell catalysts for use in methanol electrooxidation in direct methanol fuel cell applications (DMFCs). Enhanced performance of Cu–Pt compositions over Pt alone was predicted by existing computational studies in the literature. Experimental evidence from this study supports the bifunctional catalyst explanation for enhanced activity and confirms the optimum Cu:Pt ratio as Cu3Pt for this methanol electrooxidation. This ability to control the composition of a bimetallic shell can be extended to other systems where the ratio of two metals is critical for catalytic performance.

The Creation

Type 2 diabetes is one the most common metabolic diseases, which are obviously the price to pay for lifestyle changes in most people. Dangerous in itself, this disease provokes other metabolic disorders such as obesity, and neurodegenerative diseases, such as Alzheimer's disease. Pharmacologists are very active in creating drugs for these illnesses. The design of synthetic highly active analogues of incretins, peptide hormones produced by neuroendocrine cells, is one of the most promising research areas. Glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide are the best known incretin hormones. Analogues of the first peptide have already found application in medical practice. The next step in the creation of drugs for diabetes was the development of polyagonists, which combine the properties of several different peptide hormones responsible for glucose homeostasis. The combination of the properties of incretins gives hopes for a synergism net effect. In the past few years, the creation of such coagonists has been very fast. In some cases, the results of clinical trials have already been obtained; however, they often contradict each other. Making clear this difficult situation was the main motivation for writing the present review. incretins, glucan-like peptide-1, glucose-dependant insulintropic polypeptide, agonism, antagonism, type 2 diabetes, obesity

Sense Of Obligation

Abstract Tomasello offers a compelling account of the emergence of humans’ sense of obligation. We suggest that more needs to be said about the role of affect in the creation of obligations. We also argue that positive emotions such as gratitude evolved to encourage individuals to fulfill cooperative obligations without the negative quality that Tomasello proposes is inherent in obligations.
