Umgehung von Ammoniak: Von N2 zu stickstoffhaltigen Heterocyclen ohne N1‐Zwischenprodukte oder Übergangsmetalle

Angewandte Chemie, Volume 136, Issue 21, May 21, 2024.
Zwei neue heterocyclische Verbindungen werden aus Diboradiazenverbindungen synthetisiert und vervollständigen damit zweistufige Syntheserouten zu komplexen N‐Heterocyclen aus N2, die sowohl den Bedarf an Übergangsmetallreagenzien als auch das klassische Zwischenprodukt Ammoniak vollständig vermeiden und umgehen.

Bypassing Ammonia: From N2 to Nitrogen Heterocycles without N1 Intermediates or Transition Metals

Angewandte Chemie International Edition, Volume 63, Issue 21, May 21, 2024.
Two new heterocyclic species are prepared from diboradiazene compounds, thus completing two‐step routes to complex N‐heterocycles from N2 that both circumvent the need for transition metal reagents and completely bypass the traditional intermediate ammonia.

The shapeshifting Helicobacter pylori: From a corkscrew to a ball

Molecular Microbiology, Volume 121, Issue 2, Page 260-274, February 2024.
Helicobacter pylori transforms from helical rods to spherical coccoids when faced with various stresses, including starvation and temperature fluctuations. While it remains controversial whether the latter form is dormant or degenerative, a great deal of overlooked evidence points toward the existence of both.

Multiobjective Optimization of Diesel Particulate Filter Regeneration Conditions Based on Machine Learning Combined with Intelligent Algorithms

International Journal of Intelligent Systems, Volume 2024, Issue 1, 2024.
To reduce diesel emissions and fuel consumption and improve DPF regeneration performance, a multiobjective optimization method for DPF regeneration conditions, combined with nondominated sorting genetic algorithms (NSGA‐III) and a back propagation neural network (BPNN) prediction model, is proposed. In NSGA‐III, DPF regeneration temperature (T4 and T5),
