The study deals with the preparation of Ca-alginate organohydrogels and the analysis of their equilibrium swelling and mechanical properties at sub-zero temperatures. It is shown that the equilibrium degree of swelling at room temperature is noticeably affected by the concentration of co-solvents (methanol, ethanol, and 2-propanol) in the mixtures and the number of carbon atoms in the co-solvent molecules. Mechanical properties are studied in small-amplitude oscillatory tests. The data are fitted with a model that involves three material parameters. The influence of temperature is investigated in temperature-sweep oscillatory tests under a cooling-heating program, where a noticeable difference is observed between the storage and loss moduli under cooling and heating (the hysteresis curves). The hysteresis areas are affected by the cooling\/heating rate and the number of carbon atoms in the co-solvents.<\/jats:p>","DOI":"10.3390\/gels9070579","type":"journal-article","created":{"date-parts":[[2023,7,17]],"date-time":"2023-07-17T00:56:47Z","timestamp":1689555407000},"page":"579","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The Effect of Temperature on the Mechanical Properties of Alginate Gels in Water\/Alcohol Solutions"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7423-7444","authenticated-orcid":false,"given":"Haniyeh","family":"Malektaj","sequence":"first","affiliation":[{"name":"Department of Materials and Production, Aalborg University, Fibigerstraede 16, 9220 Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6049-5813","authenticated-orcid":false,"given":"Aleksey D.","family":"Drozdov","sequence":"additional","affiliation":[{"name":"Department of Materials and Production, Aalborg University, Fibigerstraede 16, 9220 Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5501-7019","authenticated-orcid":false,"given":"Jesper","family":"deClaville Christiansen","sequence":"additional","affiliation":[{"name":"Department of Materials and Production, Aalborg University, Fibigerstraede 16, 9220 Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2942","DOI":"10.1039\/C8TA10513H","article-title":"Lithium-ion batteries: Outlook on present, future, and hybridized technologies","volume":"7","author":"Kim","year":"2019","journal-title":"J.
