The approach considers the prop erties of molecular species involved as reactive intermediates in catalyti c sequences and of active centers that bind them and how they act in conce rt to select reaction channels\, often against those favored by thermodyna mics. When applied to acid-base and oxidation catalysis at oxide surfaces\ , this methodology has uncovered unprecedented details about the types of active centers involved and the elementary steps that they mediate. For in stance\, the energy required to deprotonate a solid acid and that gained b y placing the proton on a reactant molecule determine reactivity and selec tivity for solid acid catalysts\, because transformations involve the tran sfer of protons and cationic moieties at transition states. In contrast\, oxidation catalysis on redox-active oxides occurs via H-abstraction from C -H bonds in reactants and the concomitant reduction of the metal centers i n oxide catalysts. These steps are mediated by bound di-radical pairs wit h O-H and C-H bonds that are nearly formed and cleaved\, respectively\, th us making the energies of H-binding at surfaces and of C-H bond cleavage t he relevant surface and molecular descriptors of reactivity. The environme nts that surround the binding centers complement their properties through solvation effects that are able to stabilize specific bound intermediates and transition states through concerted van der Waals or H-bonding inter actions. Such stabilization becomes particularly evident (and consequenti al) when active centers reside within inorganic voids of molecular dimensi ons or are able to contact dense phases\, such as liquids or bound adlayer s. These emerging concepts and tools are bringing us closer to the purpose ful design of surfaces and environments for specific chemical transformati ons.\n\n******* *******\n UID:040000008200E00074C5B7101A82E0080000000010F1CA6CB563D901000000000000000 0100000004A3F612BBD1D8A4FB10DF2EE8AB5F3CB SUMMARY;LANGUAGE=en-US:Dr. Enrique Iglesia Reception & Seminar DTSTART;TZID=Eastern Standard Time:20230418T143000 DTEND;TZID=Eastern Standard Time:20230418T161500 CLASS:PUBLIC PRIORITY:5 DTSTAMP:20230331T140015Z TRANSP:OPAQUE STATUS:CONFIRMED SEQUENCE:0 LOCATION;LANGUAGE=en-US:FRNY Atrium/FRNY G140 X-MICROSOFT-CDO-APPT-SEQUENCE:0 X-MICROSOFT-CDO-OWNERAPPTID:-283166745 X-MICROSOFT-CDO-BUSYSTATUS:TENTATIVE X-MICROSOFT-CDO-INTENDEDSTATUS:BUSY X-MICROSOFT-CDO-ALLDAYEVENT:FALSE X-MICROSOFT-CDO-IMPORTANCE:1 X-MICROSOFT-CDO-INSTTYPE:0 X-MICROSOFT-DONOTFORWARDMEETING:FALSE X-MICROSOFT-DISALLOW-COUNTER:FALSE X-MICROSOFT-LOCATIONS:[{"DisplayName":"FRNY Atrium/FRNY G140"\,"LocationAnn otation":""\,"LocationUri":""\,"LocationStreet":""\,"LocationCity":""\,"Lo cationState":""\,"LocationCountry":""\,"LocationPostalCode":""\,"LocationF ullAddress":""}] BEGIN:VALARM DESCRIPTION:REMINDER TRIGGER;RELATED=START:-PT15M ACTION:DISPLAY END:VALARM END:VEVENT END:VCALENDAR
