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...

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...

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...
