Environmentally Friendly Films Combining Bacterial Cellulose, Chitosan, and Polyvinyl Alcohol: Effect of Water Activity on Barrier, Mechanical, and Optical Properties
Gonzalo Velazquez, Manuel Vazquez, Patricia Cazón, 2019, original scientific article

Abstract: The interest in developing new materials intended for food packaging based on bacterial cellulose is growing in the recent years. Flexible and transparent films from bacterial cellulose-chitosan-polyvinyl alcohol have shown excellent UV-barrier properties. However, this composite material interacts with ambient moisture modifying its water activity due to its hydrophilic nature. In this work, an extensive study was carried out to evaluate the changes in the properties of these films as a function of water activity. Moisture adsorption isotherm were described by the GAB method. Results showed the plasticizing effect of water molecules increasing the water vapour permeability of the samples from 1.86·10-12 to 1.17·10-11 g/m·s·Pa, the percentage of elongation from 3.25 to 36.55% and the distance to burst from 0.64 to 5.12 mm. The increase of the water activity dropped the tensile strength values from 74.76 to 38.56 MPa, Young’s modulus values from 3133.46 to 30.71 MPa and burst strength to 703.87 g. The values of the UV-barrier were maintained at the wide range of water activity. Consequently, water molecules do not affect the UV-barrier properties of the films.

Bacterial cellulose films: Evaluation of the water interaction
Manuel Vazquez, Gonzalo Velazquez, Patricia Cazón, 2020, original scientific article

Abstract: Bacterial cellulose is a biopolymer that is gaining attention due to its 3D structure, higher purity, porosity and surface area. However, this material can interact with water molecules from the surrounding environment, resulting in alterations of its properties. Hence, the purpose of this study was to analyze the modifications on the mechanical, water vapor permeability and optical properties of bacterial cellulose films as a function of the water activity. Results indicated that water acted as a plasticizer, mainly affecting mechanical and water vapor permeability properties. The moisture adsorption isotherms allowed predicting the moisture content of the bacterial cellulose films at several relative humidity conditions. Values for tensile strength and burst strength ranged from 15.50 to 22.28 MPa and from 145.03–338.10 g, respectively. The elongation and the distance to burst ranged from 1.36 to 3.71 % and from 0.39 to 1.86 mm, respectively. These values increased due to the plasticizing effect of the water molecules. Water vapor permeability values ranged from 1.35·10−12 to 3.13·10-11 g/ m s Pa, showing a significant increase up to 0.48 of water activity. Bacterial cellulose films showed excellent UV-barrier properties in the different water activities evaluated.

Podpora poslovanja malih in srednjih podjetij z računalništvom v oblaku
Nejc Bat, 2015, master's thesis

Abstract: Računalništvo v oblaku se vse bolj uveljavlja kot primerno tehnološko nadomestilo za tradicionalno računalniško opremo in skupaj z ustreznim poslovnim modelom pridobiva na tržni in tehnološki uspešnosti. V magistrskem delu je predstavljeno področje računalništva v oblaku in njegove poglavitne značilnosti. Opisane so poslovne prednosti in pomanjkljivosti računalništva v oblaku predvsem iz vidika malih in srednjih podjetij. Predstavljeni so rezultati intervjujev, ki smo jih izvedeli med izbranimi računalniškimi podjetij. Na podlagi teh intervjujev smo postavili hipoteze, katerih veljavnost smo preverili za slovensko tržišče. V ta namen smo oblikovali in izvedli spletno anketo, ki raziskuje stopnjo ozaveščenosti o možnostih računalništva v oblaku med izbranimi malimi in srednjimi podjetij. Predstavili smo rezultate ankete in podali ugotovitve glede razmer na trgu slovenskem trgu oblačnega računalništva, ki smo jih razvili iz rezultatov anket. Ugotovili smo, da so slovenska podjetja dobro seznanjena s tehnologijami računalništva v oblaku, vendar tovrstnim tehnologijam še ne zaupajo. Na osnovi analize rezultatov ankete smo oblikovali predlog poslovnega modela na podlagi metode Osterwalder Business Model Canvas. Predlagani poslovni model vključuje vidike, ki jih je potrebno upoštevati pri ponudbi izdelkov ali storitev na trgu. Poslovni model smo uporabili pri načrtovanju uvedbe storitve shranjevanja varnostnih kopij podatkov v oblaku, ki jo bo konkretno podjetje tudi uvedlo na trg.
