The need to reduce the use of fossil energy, which is running out and harmful to the environment, in response to the increasing energy demand with rapid urbanization, population growth and developing technologies reveals the necessity of research and application of technologies using renewable energy. Phase-change materials (PCM) are one of the most suitable methods for the efficient use of thermal energy originating from clean and sustainable energy sources. PCMs play important roles in a more energy-efficient world. The development of PCMs is one of the most challenging areas of study for more efficient thermal energy storage (TES) systems. This paper first explains the concept of PCMs and then describes the properties of these materials. After mentioned studies for improving the properties of PCMs, then PCM types and advantages-disadvantages are explained. Also, usage areas of PCMs in various sectors are also explained.

Formica pratensis Retzius, 1783 (Hymenoptera: Formicidae) is one of the members of the wood ants group and is represented in Europe with the hairy N morph common in the south and the less hairy P morph common in the north. The species is naturally distributed in European part of Turkey (Thrace Region) and in the neighboring parts of Bulgaria. Former studies of Bernhard Seifert showed that the N morph is the dominant morph in south Bulgaria, but the situation in Turkey is not known. In the present study, we sampled workers from some colonies of F. pratensis in Turkey and Bulgaria and obtained a pilosity data for each colony in the two countries. The comparison of our data with that of Seifert showed that the Bulgaria samples well fit with the pilosity data of P morph and Turkey samples were apparently less hairy but hairs are longer than all other populations. The results helped us to show that F. pratensis can have ecomorphological traits other than that fitting the definition of N and P morphs and that traits may differ from one to another population distributed even along in a small scale of area.
