![]() They also found that, on the other hand, it acted as an inhibitor to suppress CuO reduction against CO (carbon monoxide) oxidation. When comparing these different peroxide species and how these steps played out, researchers found that a surface layer of peroxide significantly enhanced CuO reducibility in favor of H2 oxidation. In this process, the oxidizing agent gains an electron and the reducing agent loses an electron. Redox is a combination of reduction and oxidation. In this experiment, scientists were able to alter the redox steps of catalytic oxidation reactions on an oxidized copper surface (CuO) by identifying the makeup of peroxide species formed with different gases: O2 (oxygen), H2 (hydrogen) and CO (carbon monoxide). The bond in peroxides is fairly weak, allowing other chemicals to alter its structure, which makes them very reactive. Peroxides are chemical compounds that contain two oxygen atoms linked by shared electrons. Copper, for example, can catalytically form and convert methanol into valuable fuels, so being able to control the amount of oxygen and number of electrons on copper is a key step to efficient chemical reactions. Gaining a better understanding of oxide catalysts gives researchers more control of the chemical reactions they produce, including solutions for clean energy. “They have such interesting properties and reactions, some of which are really striking.” “I’ve always liked looking at copper systems,” said Ashley Head, also a materials scientist at CFN. “So many mechanical parts that are used in industry are made of copper, so trying to understand this element of the corrosion processes is very important.” “Copper is one of the most studied and relevant surfaces, both in catalysis and in corrosion science,” said Anibal Boscoboinik, materials scientist at CFN. All these students are early in their career, having just earned their PhDs in 2022. This work was accomplished with the contributions of four PhD students in Zhou’s group: Yaguang Zhu and Jianyu Wang, the first co-authors of this paper, and Shyam Patel and Chaoran Li. ”Each of the students involved has benefited from extensive, hands-on experience in the microscopy and spectroscopy tools available at CFN.” Watson College of Engineering and Applied Science’s Department of Mechanical Engineering and the Materials Science and Engineering program at Binghamton. “A nice feature of CFN lies not only in its state-of-the-art facilities for science, but also the opportunities it provides to train young researchers,” said Guangwen Zhou, a professor at the Thomas J. The results of this work have been published in the journal Proceedings of the National Academy of Sciences. They were able to observe these quick changes with two complimentary spectroscopy methods that have not been used in this way.

Was that worth the crass intervention.? Our guest commented how terrible it made her feel. If we had given him 18% it would have been $4.50 more. ![]() bar tab was in our bill but we had tipped the bartender separately. Were excellent tippers, We took into acct the mistakes Jacob had made and his poor timing. So then he asked why such a low tip! Geez Louise! Talk about an embarrassing moment! We looked at it after and it was 14.85%. We knew Jacob was new so we didn't want to embarrass him with his boss so we said it was fine. Food was very good as usual then asked about service. Yes it's TRUE manager actually came to our table and asked how was our dinner. Then few minutes later the manager came to my husband and complained that he had given only a 10% tip. ![]() After a celebration meal for a birthday we signed our bill. We've come here often, it's very expensive but the food is good.
