“…It is one of the more natural proteins and contains two types of subunits: subunits of low molecular weight (LMW), and subunits of high molecular weight (HMW) containing intrachain and interchain disulfide bonds. Different materials have been prepared from WG, such as films, membranes, fibers, microparticles, plastic, sensing material, compounds materials, and modified wheat gluten . The characteristics of WG make it a potential candidate for the production of materials for different applications.…”

“…[19,20] Gliadin is a monomeric protein with a molecular weight of 30,000-80,000 Da and is classified in terms of electrophoresis base mobility at a low pH in ω-, α + β-, and γgliadins, depending on their molecular weight and amino acid composition, containing intrachain disulfide bonds. Different materials have been prepared from WG, such as films, [21][22][23] membranes, [24,25] fibers, [26] microparticles, [27,28] plastic, [29,30] sensing material, [31] compounds materials, [32][33][34] and modified wheat gluten.

Currently, microporous polymer materials are being studied extensively due to their attractive properties which allow for a wide potential of applications, such as prolonged-release systems (PRS). The objective of the present work was to prepare and characterize porous microparticles of wheat gluten (WG) using the electrospray technique. The effect of the physicochemical parameters of the solution and electrospray technique parameters on the morphology and size of the materials obtained was studied. For all of the concentrations of WG, porous microparticles with sphere geometry were obtained. At higher concentrations of WG (8% w/v), higher values of viscosity (0.32405 ± 0.002 Pa·s), density (0.997 ± 0.0005 g/cm 3 ), and particle size (1.42 ± 0.71 μm) were obtained, while at lower concentration, high stability rheological is presented, which exhibited Newtonian fluid behavior. Characterization by scanning electron microscopy (SEM), Fourier transform-infrared spectroscopy (FT-IR), and X-ray diffraction indicated that the material obtained has a potential application in the PRS industry.

“…Deeper penetration ensures stronger anchoring of the coating, which improves the durability of the surface system. Both the wood and the coating influence penetration (Bessières et al 2013;Kamke and Lee 2007;Khosravi et al 2015;Paris and Kamke 2015). Experimentally, the penetration of a coating in the wood is usually measured at random, in sampled cross sections (Chandler et al 2005).…”

Treatment of wood with atmospheric plasma discharge: study of the treatment process, dynamic wettability and interactions with a waterborne coating

et al. 2020

Plasma treatment is becoming a mature technique for modification of surfaces of various materials, including wood. A better insight in the treatment process and the impact of the plasma on properties of wood bulk are still needed. The study was performed on Norway spruce and common beech wood, as well as their thermally modified variations. The formations of the airborne discharge, as well as mass changes of the treated wood, were monitored. The impact of such treatment on wood-coating interaction was investigated by evaluating the dynamic wettability and penetration into wood. At the wood surface, plasma streamers were observed more intense on denser latewood regions. Wood mass loss was higher with increasing number of passes through the plasma discharge and was lower for thermally modified wood than for unmodified wood. Plasma treatment increased the surface free energy of all wood species and lowered the contact angles of a waterborne coating, these together indicating enhanced wettability after treatment. Finally, the distribution and penetration depth of the coating were studied with X-ray microtomography. It was found that the coating penetrated deeper into beech than into spruce wood. However, the treatment with plasma increased the penetration of the coating only into spruce wood.
