A series of 12 asphaltene samples extracted from heavy oils and the oxidized bitumen of
different origin has been studied with high-frequency W-band (94 GHz) pulsed electron …

The paper demonstrated the increase of the surface area and meso-and microporosity
volume with the low concentration Mg-substitution introduction during the hydroxyapatite …

Novel materials with a variety of properties, such as biocompatibility, antibacterial activity,
interconnected porosity, and functionalities combined in one, are required for regenerative …

Calcium phosphates (CaP) based materials are widely recognized as the most suitable
matrix for bone tissue engineering. The cationic and anionic substitutions of CaP structure …

This article presents the results of a study of radiation-induced defects in various synthetic
calcium phosphate (CP) powder materials (hydroxyapatite—HA and octacalcium phosphate …

Structural characterization of metalloporphyrins in complex systems, such as native
hydrocarbons, has been the focus of scientific and industrial interests for many years. We …

The structural properties of crude oils and asphaltenes, especially related to the dynamics of
their aggregation, have been investigated by different experimental and theoretical methods …

We demonstrate the application of the combined experimental–computational approach for
studying the anionic impurities in hydroxyapatite (HAp). Influence of the carbonation level (x) …

It is desirable to develop semiconductors with simultaneously multiple responses to single
stimuli. Herein, a thermally responsive hybrid semiconductor (AEV)[Pb2Br8](AEV4+= 1, 1 …

The interplay of oppositely charged substitutions in the structure of hydroxyapatite (HAp)
nanopowders is investigated on the atomic level by pulsed electron paramagnetic …
