Phase change materials (PCM) are attractive energy storage technologies due to their high energy storage density and the ability to reversible absorb and release thermal energy at a nearly constant temperature. Polymers and polymer-based eutectic mixtures are promising PCMs. This study aims to investigate heat properties (melting temperature ...

 One of the most important factors in cooling systems is ensuring tightness. For this, it is necessary to form strong aluminum copper pipe connections. These connections working under vibration should not leak during long-term use. In this study, aluminum and copper pipes joined by eutectic welding and brazing method were investigated. Tensile...

 This study aimed to examine the influence of adding selected spices on the physicochemical properties of fresh cream cheese. Six different samples of fresh cream cheese were produced in the milk processing plant (mini cheese factory). The first sample was marked as a control, without the addition of spices, and the other five were produced wi...

 Apricot (Prunus armeniaca) is a continental stone fruit that belongs to the Rosaceae family. The aim of this work was to determine the chemical properties of shelled and unshelled apricot seeds, as well as the physico-chemical and antioxidant characteristics of the oils obtained from these seeds. The content of moisture, crude ash, crude prot...

 Air suspension bellows is a rubber-based polymer material that needs to be used in heavyduty vehicles. The service life of the rubber and court cloth used as the bellows material changes due to the process. While premature damage to the bellows increases the risk of accidents, frequent replacements cause an increase in costs. In this study, ...
