Thus, wood material polysaccharides exhibit amphoteric properties, forming salts with alkali metal solutions, which characterizes wood material as a weak organic solid acid.
The use of phosphorus compounds is due to the properties of inhibitors of the radical-chain reaction of combustion.
In the conditions of providing fire-retardant properties of wood material, the interaction with inorganic acid will also be predominant.
To give the surface of the sample the properties of conductivity, ion sputtering of the metal under vacuum conditions was used.

Because of the properties of PO43- and AsO43- are very similar, so they often form various types of arsenate-phosphate solid solutions.
There are few experimental data on the thermodynamic properties of calcium arsenate hydroxyapatite [Ca5(AsO4)3OH] in literature.
The incorporation of trace elements into Ca5(PO4)3OH and Ca5(PO4)3OH-like minerals has a considerable influence the mechanical and physiochemical properties of the crystals and significantly affects their reactivity and solubility [30].
The thermodynamic and kinetic properties of svabite dissolution have never been investigated by anyone but Zhu [24].

Introduction Concrete is the most widespread construction material because it is easily produced and provides excellent mechanical properties in long-term.
A common drawback of this material is the formation of small-sized cracks, occurring due to shrinkage or because of the presence of physical-chemical corrosion factors, that reduce the service life of the structure and increase maintenance costs.
A cementitious material with inbuilt self-healing properties and competitive cost could be considered as a solution for confronting the problem.
Two binders (Table 2) were employed; the first (C1) was used as control, whereas C2 included chemical additives that are supposed to provide the self-healing properties to the final material.
Their properties are reported in Table 4.

Viscoelastic and Flow Properties of the Dough with RS During Proofing.
The structural changes of dough that occurred during proofing at 25°C were decisive factors for bubble formation and stability and the final baked texture (Shelke, 1990[17]; Duggan, 2008[18]).

Phase transitions, thermal properties, ionic conductivities and electrochemical stabilities are investigated to characterize the alternating copolymer electrolyte.
Firstly, cross-linking is an effective way to restrain the crystallization and maintain thermal and mechanical stability [6].
The maleic anhydride units on the backbone also affect the phase transitions of the solid polymer electrolyte.
DSC can be used to character the crystallization property.
However, the maleic anhydride does not behave a positive factor to the ionic conductivity.

Inkjet printing of electrochemical sensors is commonly based on the use of metal nanoparticle inks whose conducting properties exceed that of their bulk counterpart [4], [5].
Factors such as surface tension, viscosity, nanoparticle concentration, and solvent drying rate play an important role in achieving stable, single, satellite-free drops upon jetting [18].
Cyclic voltammetry (CV) is an electrochemical technique commonly employed for investigating the reduction-oxidation process in the analyte solution, and the surface properties of the electrodes.
To investigate the properties of the inkjet-printed (IJP) three-electrode system, the diffusion-controlled electrode reaction of the widely studied, reversible ferri(III)/ferro(II)cyanide redox couple was conducted using cyclic voltammetry (CV).
