These proceedings, comprising 66 peer-review papers, are divided into 10 chapters covering: fundamental aspects (of positron and positronium chemistry), membranes, molecular systems, confined systems, liquids, polymers, porous systems, non-metallic materials, nuclear materials, experimental techniques.
This work owes a lot to the authors’ commitment to positron and positronium chemistry and related subjects.

The identification of unswept cores also has the potential to help unravel the evolution
of grain boundary chemistry during grain boundary migration.
It is based on a data structure that describes a polycrystalline material using a two-dimensional network of nodes and connecting boundaries.
Data on the geometry of the structure and attributes such as dislocation density, viscosity and stress-state of nodes and polygons are stored in an Elle data file.
Oscillatory zoning predicted by cyclical grain boundary chemistry variations during grain growth.
(2) These remnant unswept cores have the potential, when they can be correctly identified, to resolve the pre-growth grain boundary geometry and intra-granular chemistry of a material, and perhaps even the grain boundary kinematics and the evolution of the grain boundary chemistry

Keywords: Cellulose, Nano-structure, Nano-crystallites, Paracrystallinity, Physico-chemistry
Abstract.
This polymer has complicated multi-level supermolecular structure.
Therefore cellulose can be a pronounced and eminent representative of nano-structured matters.
In this paper, physico-chemistry of the nano-structured cellulose is discussed.
Due to highly developed specific surface and excess free energy (thermodynamic potential) the nano-phase has an expressed tendency to form larger structures via aggregation and agglomeration.

Modulation of the metallic oxide properties through of soft chemistry
techniques for several applications
Altamirano-Juárez, D.
The soft chemistry technique is shown as an option to obtain films of metallic oxide for their use optoelectronic devices.
The functionality of a device is strongly attributed to the characteristics of the linking of its binding energy with the formed structures.
Therefore, soft chemistry techniques are cheaper.
The traps of holes were located at similar levels to those reported by Studenikin et al. for thin films of zinc oxide obtained by another soft chemistry technique [18].

A Simplified Preparation Method of Silicon-Substituted
Calcium Phosphates According to Green Chemistry Principles
S.V.
A simplified preparation method of silicon-substituted calcium phosphates with a very high yield (close to 100%) has been elaborated, according to the principles of Green Chemistry.
These features oppose the modern requirements of Green Chemistry.
In order to prepare silicon-substituted calcium phosphates, ions of calcium, phosphate and silicon must meet altogether and form the desired structure.
