The addition of ACN (solvent acetonitrile) to EMIMBF4 (methylimidazolium tetrafluoroborate) significantly lowers the internal resistance and improves the electrochemical stability by several orders of magnitude, which is due to a decrease in viscosity and prevention of the decomposition of the ionic liquid. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<section class=\"elementor-section

into valuable \u03b1-hydroxyesters. Biorenewable methyl- and ethyl-5-hydroxylevulinates can be converted into a series of practically valuable, unsymmetrical diesters of 2-hydroxyglutaric acid in good yields. 2-Hydroxyglutarate has cardioprotective, nephroprotective and antiasthmatic properties, and is also an oncometabolite and finds application as a biomarker in cancer monitoring, and the method is also used for modifications of steroid molecules such as cortisone, hydrocortisone, prednisone and prednisolone, which have analgesic and anti-inflammatory properties.  <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-204f3ef elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"204f3ef\" data-element_type=\"section\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[]}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-b09d452\" data-id=\"b09d452\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-9f94b61 elementor-mobile-align-center elementor-widget elementor-widget-button\" data-id=\"9f94b61\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/www.orgchm.bas.bg\/EN\/index_en.html\" target=\"_blank\" rel=\"nofollow\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t<span class=\"elementor-button-icon\">\n\t\t\t\t<i aria-hidden=\"true\" class=\"fas fa-chevron-right\"><\/i>\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Institute of Organic Chemistry with Centre of Phytochemistry<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a364851 elementor-view-stacked elementor-shape-square elementor-position-inline-start elementor-mobile-position-block-start elementor-widget elementor-widget-icon-box\" data-id=\"a364851\" data-element_type=\"widget\" data-widget_type=\"icon-box.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-icon-box-wrapper\">\n\n\t\t\t\t\t\t<div class=\"elementor-icon-box-icon\">\n\t\t\t\t<a href=\"mailto:office@jic.bas.bg\" class=\"elementor-icon\" tabindex=\"-1\" aria-label=\"Contact:\">\n\t\t\t\t<i aria-hidden=\"true\" class=\"fas fa-envelope\"><\/i>\t\t\t\t<\/a>\n\t\t\t<\/div>\n\t\t\t\n\t\t\t\t\t\t<div class=\"elementor-icon-box-content\">\n\n\t\t\t\t\t\t\t\t\t<h3 class=\"elementor-icon-box-title\">\n\t\t\t\t\t\t<a href=\"mailto:office@jic.bas.bg\" >\n\t\t\t\t\t\t\tContact:\t\t\t\t\t\t<\/a>\n\t\t\t\t\t<\/h3>\n\t\t\t\t\n\t\t\t\t\t\t\t\t\t<p class=\"elementor-icon-box-description\">\n\t\t\t\t\t\toffice@jic.bas.bg\t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>organic materials New supercapacitors with activated carbon from biomass Development of new supercapacitors with significantly lower internal resistance and better electrochemical stability than previously existing ones using an electrolyte containing an ionic liquid and activated carbon derived from biomass has been carried out at the Institute of Electrochemistry and Energy Systems.
