Nanosecond Hyperquenching for Electron Cryo‐Microscopy Without Air‐Water Interface Artifacts

open access: yesChemistry – A European Journal, EarlyView.
A novel method for the ultrafast vitrification of the biological assemblies is assayed by the electron cryotomography. Protein specimens prepared by this method inherently lack the spatial/structural artifacts, which derive from the surface tension at the air‐water interface (AWI).

Characterization of biodegradable food packaging films prepared with polyamide 4: Influence of molecular weight and environmental humidity

open access: yesFood Bioengineering, Volume 1, Issue 3-4, Page 276-288, December 2022., 2022
Colorless and translucent polyamide 4 (PA4) films, which are both bio‐based and biodegradable, were prepared by the solution casting method in a dual‐solvent system. The physical properties of single PA4 films were originally characterized, and the effects of molecular weight and environmental humidity on PA4 were investigated. Abstract The development

Tuning Decomposition Temperature: A Structural Study of Ligand Directed Bonding and Fluxionality

open access: yesChemistry – A European Journal, EarlyView.
In this work, we have investigated the design and synthesis of aluminium compounds via systematic variation of ligand type. This is the first example of a ligand directed design and study of aluminium compounds which decompose at low temperatures (<200 °C). Their dynamic properties have also been investigated, with a focus on the decomposition profiles.

Mechanisms of the Ammonium Sulfate Roasting of Spent Lithium‐Ion Batteries

open access: yesGlobal Challenges, Volume 6, Issue 12, December 2022., 2022
Thermogravimetric experiments are performed to analyze the mechanism of the sulfation conversion process. First, the reaction activation energies of sulfate‐assisted roasting are calculated using two different models. Then, nucleation and growth are determined and verified as the sulfation reaction model by the Šatava‐Šesták method.
