ΑΝΑΠΤΥΞΗ ΤΕΧΝΙΚΩΝ ΓΙΑ ΤΗ ΒΕΛΤΙΩΣΗ ΤΗΣ ΠΟΙΟΤΗΤΑΣ ΤΩΝ ΔΙΣΚΙΩΝ ΚΑΙ ΤΗΝ ΑΠΟΔΕΣΜΕΥΣΗΦΑΡΜΑΚΩΝ ΑΠΟ ΕΠΙΚΑΛΥΜΜΕΝΕΣ ΣΤΕΡΕΕΣ ΦΑΡΜΑΚΟΤΕΧΝΙΚΕΣ ΜΟΡΦΕΣ
… AMOUNT OF MOISTURE AND EXIBIT A LOW RATE OF WATER VAPOR PERMEABILITY. THE NEWLY CONSTRUCTED FILM ALLOWS THE INCORPORATION AND RELEASE OF DRUGS (INDOMETHACIN, PHENYL-PROPANOLAMINE-HCL, PREDNISOLONE) DEPENDENT OR INDEPENDENT ON THE PH OF THE ENVIRONMENT.

TEMPO-oxidized Nanofibrillated Cellulose Film (NFC) incorporating Graphene Oxide (GO) Nanofillers
… rate (OTR) of TOCN/GO composite decreased. The water vapor permeability (WVP) was not significantly affected by the reinforcement with GO, but the moderate oxidation enhanced the barrier properties. Ultimately, the newly fabricated TOCN/GO composite can be utilized in a wide range of life …

Cross-Laminated Timber made of Unmodified and Thermally Modified Yellow-Poplar Lumber
… through four objectives: (1) determining the water vapor permeability and resistance factor of CLT made from unmodified wood and hybrid CLT with TMW outer layers, including the influence of the one-component polyurethane (PUR) adhesive layer; (2) predicting long-term moisture diffusion …

Free-radical maleation of poly(butylene adipate-co-terephthalate) in supercritical carbon dioxide and its effect on the percolation and deformation mechanism of layered silicate nanocomposites
… packaging applications can mitigate the water, solvents, and energy required for processing plastic waste. PBAT exhibits exceptional elongational properties, but its moderate water vapor permeability and low tensile modulus limit the applications in which PBAT can be employed. In this …

Development and characterization of edible films made from four dietary fibers -pectin, guar gum, locust bean gum, and hydroxypropyl methylcellulose
… content, partial dissolution/dissolution time, water vapor permeability, color of films, and viscosity of solutions of different concentrations of each polymer and different concentrations of glycerol. I also analyzed and compared the test results of guar gum, locust bean gum, pectin, and …

Multifunctional bio-composites for forestry and agricultural applications
… due to over-exploitation of land and water, urban sprawl, tourism and unplanned industrialisation. To address these problems, it is necessary to develop technological solutions to support planting and forestry operations, even on degraded land. On the basis of these considerations, …

The Moisture Transport Properties of Cement Mortar under Salt Spray Deposition
… patterns of cement mortars with different water-cement ratios and surface evaporation conditions were determined after 120 days of semi-immersion in a 5 wt% NaCl solution. Both the clogging of internal pores by salt crystals and the sealing of external surfaces with resin significantly …

Incorporation of selected plant extracts into edible chitosan films and the effect on the antiviral, antibacterial and mechanical properties of the material
… green tea extract (GTE) dissolved in deionized water and also incorporated into chitosan film forming solutions (FFS) and into chitosan films. For comparison, the antibacterial activity of the films was also investigated against Listeria innocua and Escherichia coli K12. The viral infectivity …

Use of end-of-waste foamed fibers and aggregates into a cementitious mortar
… mortars reported good results for capillary water absorption, sulfate attack and plastic shrinkage cracking. In particular, fibers length and volume fraction are key parameters in controlling plastic shrinkage cracking. Moreover, mortar samples containing foamed fibers displayed a better …

Wool fabric plasma treatment: resulting properties evaluation and applications in field
… as well as the precious resource given by freshwater. In this view, plasma treatment of textile materials appears very promising in replacing a number of current wet chemical processes, or at least, intensifying them. Plasma is commonly known as the fourth state of matter, being constituted by …
