Phenomenology of Gluino Searches at the Tevatron

, 1993
Present data indicates that the gluino (if it exists) must be heavier than about 95~GeV. During the next few years as the Tevatron integrated luminosity increases, gluino searches will be able to probe the mass range between 100 and 200~GeV.

Liganden der Lipidtasche induzieren allosterische Modulation der Proteindynamik im Bereich des aktiven Zentrums der Proteinkinase p38α

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 ...

Structural Insights Into CO2 Transport Pathways in a W‐Formate Dehydrogenase: Structural Basis for CO2 Reduction

Angewandte Chemie, EarlyView.
Integrated structural analysis of N. vulgaris formate dehydrogenase AB, an enzyme with applications in climate change mitigation, is reported. The substrate/product diffusion pathways were fully mapped, and a retention site was identified that transiently holds substrates and has a key role in CO2‐reducing activity.

Reversible metal cluster formation on Nitrogen-doped carbon controlling electrocatalyst particle size with subnanometer accuracy

Nature Communications
Copper and nitrogen co-doped carbon catalysts exhibit a remarkable behavior during the electrocatalytic CO2 reduction (CO2RR), namely, the formation of metal nanoparticles from Cu single atoms, and their subsequent reversible redispersion.

Dibenzazepin‐verbrückte Netzwerk‐Polymer‐Phthalocyanine als abbaubare heterogene Photokatalysatoren

Angewandte Chemie, EarlyView.
Photodynamische Dibenzazepin‐Brücke wurde in Zink‐ und Kobalt‐Netzwerk‐Polymer‐Phthalocyanine (NP‐Pcs) eingeführt, um abbaubare heterogene Photokatalysatoren zu erhalten. Zum ersten Mal spielt die Bestrahlung mit Licht eine Schlüsselrolle beim „Design, der Verwendung und dem Abbau” von NP‐Pcs.

Atomically Dispersed Cobalt on Ionic Carbon Nitrides for Selective and Efficient Nitrate Electroreduction to Ammonia

Angewandte Chemie, EarlyView.
By exploiting the structural benefits of PHI, we synthesized CoPHI with atomically dispersed cobalt sites at high density. This architecture enables efficient nitrate ion adsorption, promotes water dissociation, and enhances *H generation on the catalyst surface, thereby significantly improving electrochemical nitrate reduction performance.

A Large Magneto‐Optical Trap of Cadmium Atoms Loaded From a Cryogenic Buffer Gas Beam

Natural Sciences
We demonstrate rapid loading of a magneto‐optical trap (MOT) of cadmium atoms from a pulsed cryogenic helium buffer gas beam, overcoming strong photoionization losses.

Kontrollierter Transport und lichtinduzierte Freisetzung von Magic Spot Nukleotiden in Escherichia coli

Angewandte Chemie, EarlyView.
We synthesized photocaged, clickable and isotope‐labeled “magic spot” Nucleotides and delivered them into Escherichia coli comparing different approaches. Light‐controlled release inside living cells enabled tracking of their conversion from pppGpp to ppGpp by capillary electrophoresis mass spectrometry and revealed their impact on the growth rate of a

Der Nicht‐Adiabatische Charakter von Substituenteneffekten in Azobenzol

Angewandte Chemie, EarlyView.
Vereinheitlichung Nicht‐Adiabatischen Schaltens: die thermische Z→E Isomerisierung von para‐substitutierten Azobenzolen verläuft über einen einzelnen Reaktionsweg mit nicht‐adiabatischem Charakter. Anstatt eines mechanistischen Wechsels spiegelt der bekannte V‐förmige Hammett Graph ein Artefakt des σp Parameters, zeigt so die Grenzen von DFT auf und ...
