Effect of pH on the Electrochemical Behavior and Nitrogen Reduction Reaction Activity of Ti2N Nitride MXene

open access: yesAdvanced Materials Interfaces, 2023
Nitrogen reduction reaction (NRR) is used to convert nitrogen (N2) to ammonia (NH3) at ambient conditions. In general, acidic electrolytes are used to provide protons (H+), however, this leads to low selectivity due to H2 formation via the hydrogen ...

Torque, but not FliL, regulates mechanosensitive flagellar motor-function

open access: yesScientific Reports, 2017
The stator-complex in the bacterial flagellar motor is responsible for surface-sensing. It remodels in response to perturbations in viscous loads, recruiting additional stator-units as the load increases.

Heterogeneous Distribution of Proton Motive Force in Nonheritable Antibiotic Resistance

open access: yesmBio, 2023
Bacterial infections that are difficult to eradicate are often treated by sequentially exposing the bacteria to different antibiotics. Although effective, this approach can give rise to epigenetic or other phenomena that may help some cells adapt to and ...

"This isn't something I can fake": Reactions to Glee's representations of disability

open access: yesTransformative Works and Cultures, 2010
Angered by how Glee's creators depict the character of Artie giving up on his dreams of being a dancer, I demonstrate the show's ignorance of integrated dance and wheelchair ballroom dance.

ARTI APPLICATE, ARTI INDUSTRIALI: UNA QUESTIONE STRATEGICA

open access: yesIstituto Lombardo - Accademia di Scienze e Lettere - Incontri di Studio, 1970
The idea of a quality of life based on high handcraft-manufacturing requirements in their interaction with an industrialised society has an important part – beyond the particular case - in the Expo 2015 project. It’s in the post war period that in Milan the strategic question of a “social art” is raised, as defined by the experience of the artistic ...

Periodic Halpha variations in GL 581: Further evidence for an activity origin to GL 581d

open access: yes, 2015
Radial velocity measurements showed evidence that the M dwarf GL 581 might host a planet, GL 581d, in the so-called "habitable zone" of the star. A study of Halpha in GL 581 demonstrated that changes in this activity indicator correlated with radial ...

Integration of surface-enhanced Raman spectroscopy (SERS) and machine learning tools for coffee beverage classification

open access: yesDigital Chemical Engineering, 2022
Surface-enhanced Raman spectroscopy (SERS) is a powerful tool for molecule identification. However, profiling complex samples remains a challenge because SERS peaks are likely to overlap, confounding features when multiple analytes are present in a ...
