UDP-N-acetilglicosamina enolpiruvil transferase: determinação dos estados de protonação de resíduos de aminoácidos do sítio ativo pelo método PM6

Química Nova, 2012
UDP-N-acetylglucosamine-enolpyruvyl transferase (MurA) catalyzes the reaction between phosphoenol pyruvate and UDP-N-acetylglucosamine. We present a theoretical approach using the semiempirical PM6 method for defining protonation state of three active ...

Baryon asymmetry from leptogenesis with four zero neutrino Yukawa textures [PDF]

, 2011
The generation of the right amount of baryon asymmetry $\eta$ of the Universe from supersymmetric leptogenesis is studied within the type-I seesaw framework with three heavy singlet Majorana neutrinos $N_i\,\,(i = 1,2,3)$ and their superpartners.

Tuning the Circularly Polarized Reflection from Cholesteric Hydroxypropyl Cellulose Using Molecular Photoswitches

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Molecular photoswitches dispersed in a cholesteric hydroxypropyl cellulose mesophase enable reversible, light‐driven tuning of structural color and polarization. Enantiomer‐specific effects and light‐responsive patterning highlight the potential of dynamic, cellulose‐based photonic materials.

Exploring sources of ice crystals in cirrus clouds: comparative analysis of two ice nucleation schemes in CAM6 [PDF]

Atmospheric Chemistry and Physics
Ice crystal formation in cirrus clouds is poorly understood, and its representation remains a challenge in global climate models. To enhance the understanding, a novel ice nucleation parameterization based on the Kärcher (2022) (K22) scheme is introduced
