Experimental Isolation of Single Impact, Cumulative Energy, Aging, and Liquid‐Assisted Grinding Effects in Mechanochemical Reactions

open access: yesAngewandte Chemie, EarlyView.
An experimental framework is introduced to isolate single‐impact and cumulative energy within a mechanochemical system. The guided, stepwise approach highlights the fundamental roles of impact events, post‐impact reactivity, and liquid‐assisted grinding additives in all‐solid mechanochemical reactions.

Increase of solubility and transmembrane permeability of niclosamide from its mechanochemically synthesized solid dispersions

open access: yesChimica Techno Acta, 2023
More than 4.5 billion people worldwide are affected by parasitic diseases, with helminth infections accounting for 99% of the total number. Niclosamide (NS) is a weakly acidic active pharmaceutical ingredient (API) used to treat helminth infections ...

Ouabain-induced cytoplasmic vesicles and their role in cell volume maintenance [PDF]

open access: yes, 2015
Cellular swelling is controlled by an active mechanism of cell volume regulation driven by a Na+/K+-dependent ATPase and by aquaporins which translocate water along the osmotic gradient. Na+/K+-pump may be blocked by ouabain, a digitalic derivative, by

Pre-Activation as a Route for Tuning the Kinetics of Mechanochemical Transformations. [PDF]

open access: yesAngew Chem Int Ed Engl
The kinetics of mechanochemical reactions can be markedly altered through the selective pre‐activation of starting reagents, as revealed through reaction monitoring using time‐resolved in situ powder X‐ray diffraction and ab initio density functional theory simulation.

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents

open access: yesAdvanced Functional Materials, EarlyView.
Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...

Properties of tug-of-war model for cargo transport by molecular motors

open access: yes, 2009
Molecular motors are essential components for the biophysical functions of the cell. Our current quantitative understanding of how multiple motors move along a single track is not complete; even though models and theories for single motor chemomechanics ...
