Corrosion behaviour of quasicrystal Al – Cu – Fe and Al – Ni – Fe alloys in acidic solutions [PDF]

open access: yesМеталознавство та обробка металів, 2018
Due to unique physical and mechanical properties of quasicrystals, the Al – Cu – Fe and Al – Ni – Fe alloys can be applied as coatings for parts working under friction, abrasive wear etc.

Dynamic Potential-Ph Diagrams Application to Electrocatalysts for Water Oxidation [PDF]

open access: yes, 2011
The construction and use of "dynamic potential-pH diagrams" (DPPDs), that are intended to extend the usefulness of thermodynamic Pourbaix diagrams to include kinetic considerations is described.

Preparation of PtRu/C Electrocatalysts by Borohydride Reduction for Methanol Oxidation in Acidic and Alkaline Medium

open access: yesInternational Journal of Electrochemical Science, 2017
PtRu/C electrocatalysts were performed according to the borohydride reduction method and characterized by X–ray diffraction (XRD), energy dispersive analysis (EDX), transmission electron microscopy, cyclic voltammetry (CV) and polarization curves in ...

pH-Sensitive Chitosan–Heparin Nanoparticles for Effective Delivery of Genetic Drugs into Epithelial Cells [PDF]

open access: yes, 2019
Chitosan has been extensively studied as a genetic drug delivery platform. However, its efficiency is limited by the strength of DNA and RNA binding.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Long-time evolution of sequestered CO$_2$ in porous media [PDF]

open access: yes, 2014
CO$_2$ sequestration in subsurface reservoirs is important for limiting atmospheric CO$_2$ concentrations. However, a complete physical picture able to predict the structure developing within the porous medium is lacking.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

The yhiM gene codes for an inner membrane protein involved in GABA export in Escherichia coli [PDF]

open access: yes, 2017
In order to survive the exposure to acid pH, Escherichia coli activates molecular circuits leading from acid tolerance to extreme acid resistance (AR). The activation of the different circuits involves several global and specific regulators affecting the

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only
