Recovery of Yttrium Oxide from Titanium-Aluminium based wastes
Yttrium belongs to the rare earth elements and critical metals.Yttrium oxide is mostly used in fluoroscent lamps, production ofelectrodes, in electronic filters, lasers, superconductors and asadditives in various titanium-aluminium materials to improve theirproperties. Recovery of yttrium oxide from secondary sourcessuch as red mud, coatings from c...

Mathematical aspects of analysis of maximal pressure-volume work function
The paper presents relation for maximal pressure-volume work for closed systems by using principles of I and II law of thermodynamics, used in reversible processes in which mechanical and thermal balance has been achieved. For full interpretation of this problem for two characteristic cases, graphical review in p-v diagram is given, where in an obv...

Reducing Packaging Waste – Mechanical Characteristics and Network Parameters of the Gelatin-Based Thin Film for Cruciferous Vegetables Packaging
The role of the materials used for packaging is to protect innercontent from external, mostly negative, factors. Besides beingsafe, and with good mechanical properties, these materials needto align with other consumers’ needs and demands, being bothattractive and authentic, while at the same time meetingecological requirements. Gelatin-based ...

Pigmented maize - a potential source of β-carotene and α-tocopherol
Among cereals, maize has the highest content of bioavailable micronutrients in grain, particularly β-carotene and α-tocopherol, which makes this crop the most appropriate for biofortification. Great genetic variability is a valuable source of micronutrients, and genotypes with enhanced grain content could be used for improvement of comme...

Characterisation and antimicrobial activity of silver nanoparticles derived from Vascellum pratense polysaccharide extract and sodium citrate
Silver nanoparticles (AgNPs) were synthesized by “green”, cheap hydrothermal method in an autoclave using sodium citrate and Vascellum pratense polysaccharide extract as reducing and stabilizing agents. Presence of spherical AgNPs was confirmed by UV-VIS spectrophotometry and scanning electron microscopy; particle size was determined as...

Review of electrospray observations and theory
While a liquid is dripping out of a capillary tube, there is a possibility to affect the characteristics of the exiting flow in certain ways. One of the ways already used is by introducing an electric field that can be used to change the average droplet diameter and the droplet size distribution. This process is called electrospraying, while the th...
