Rural–Urban Change in Highland Peru: Perceived Impacts and Preferred Performance
Mountain Research and DevelopmentIn recent decades, the mountains of Latin America have undergone massive rural–urban change. In Peru, this has led to strong growth of population and settlement on the spatially limited valley floors of the Quechua elevational zone, which is part of a ...

Change, Collective Action, and Cultural Resilience in Páramo Management in Ecuador
Mountain Research and Development, 2019 This study examines how agricultural frontier expansion and grazing practices develop in the páramos under communal tenure in the northern Ecuadorian Andes and how rules to control them emerge within communal governance.

Angewandte Chemie, EarlyView.Der Einsatz von Dimesitylphosphid als höheres Homolog der etablierten Amidoliganden für Charge‐Transfer‐Kupfer(I)‐Komplexe führt zu einer Rotverschiebung der Emission um 3645 cm–1 in den rot‐orangen Spektralbereich im Festkörper sowie in den NIR‐Bereich in Lösung. Die thermisch‐aktivierte verzögerte Fluoreszenz weist hohe Dissymmetriefaktoren von glum =

Proteinvermittelte Kupfer‐Redoxregulation: Rolle von Disulfidbrücken und allosterischer Modulation
Angewandte Chemie, EarlyView.Copper binding triggers structural changes that expose a reactive disulphide bridge, enabling intrinsic Cu(II) reduction in folded proteins. SAXS, XAS, and QM/MM simulations reveal how globular proteins such as HSA and SOD1 employ disulphide‐mediated dynamics to modulate site accessibility and control copper redox chemistry.

Angewandte Chemie, EarlyView.Diese Studie untersucht den Einfluss von Spuren diverser Elemente des p‐Blocks in der elektrochemischen reduktiven Aminierung, wobei sich für Pb mit Bi eine weniger toxische Alternative gezeigt hat. Die Verwendung von Bi als Additiv wurde weiter optimiert, indem der Einfluss der Additivkonzentration, der Reaktionstemperatur und des Kathodenmaterials ...

Angewandte Chemie, EarlyView.Bei der Suche nach neuen allosterischen Stellen in der Serin/Threonin‐Kinase p38α deckt die NMR‐Spektroskopie eine dynamische Kopplung zwischen dem katalytischen Zentrum und der Lipidtasche auf. Die Ergebnisse offenbaren bewegungsbezogene Interdependenzen, die entfernte Regionen des Enzyms miteinander verbinden, was die Lipidtasche als ...
