Temperature and Stirring Times Influence on Size Distribution, Diameter and Concentration of Microdroplets (English)
Abstract [sv]

Syftet med denna studie var att tillverka och mäta koncentration, diameter och storleksfördelning för mikrodroppar under olika temperaturer och omrörningstider. Datainsamlingen kom från flera observationer vilket bidrog till en grundlig förståelse för dess egenskaper under olika omständigheter.

Ett av de viktigaste resultaten var att temperaturen hade en viktig roll för koncentrationen av mikrodroppar. En minskning av koncentrationsnivåerna observerades vid lägre temperaturer. Vidare noterades att omrörningstiden också spelade en roll, betydande minskningar av det totala antalet mikrodroppar observerades under längre omrörningstider.

Mikrodropparnas medeldiameter hade storlekar som låg inom acceptabla intervaller i alla prov. De medeldiametrar som observerades låg inom ett intervall på 3,98 μm till 8,18 μm men större enskilda mikrodroppar med diameter över 10 μm kunde också hittas.

Resultaten gav vägledande faktorer för ytterligare undersökningar för att fastställa dess medicinska tillämpningar. Framtida studier bör fortsätta att analysera dessa parametrar för att ytterligare optimera mikrodroppar för användning inom områden som ultraljudsavbildning eller läkemedelsleverans.

Abstract [en]

The aim of this study was to fabricate and measure the concentration, diameter, size distribution of microdroplets under different temperatures and stirring times. The data collection came from several observations which provided a thorough understanding of its properties under different circumstances.

One of the key findings was that the temperature had an important role in the concentration of microdroplets. A decrease in concentration levels was observed at lower temperatures. Furthermore, it was noted that stirring time also played a role, leading to significant reductions in the total number of microdroplets when observed for longer stirring times.

The mean diameters of the microdroplets had sizes that were within acceptable ranges in all samples. The mean diameters observed ranged from sizes between 3.98 μm and 8.18 μm but single microdroplets with diameters greater than 10 μm could also be found and observed.

The results provided guiding factors for further investigations to determine its medical applications. Future studies should continue to analyze these parameters to further optimize microdroplets for use in areas such as ultrasound imaging or drug delivery.
