Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

open access: yesAdvanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Significance of Histidine Hydrogen–Deuterium Exchange Mass Spectrometry in Protein Structural Biology

open access: yesBiology
Histidine residues play crucial roles in shaping the function and structure of proteins due to their unique ability to act as both acids and bases. In other words, they can serve as proton donors and acceptors at physiological pH.

Acidic dissociation constant and related thermodynamic quantities for diethanolammonium ion in water from 0 to 50 °C

open access: yes, 1962
The dissociation constants of diethanolamine (2:2'-dihydroxydiethylamine) and its conjugate acid were determined by electromotive force measurements of the cell [formula] in the temperature range 0 to 50 °C. The acidic dissociation constant (Kbh) of the
