This study provides the surface characteristics (surface energy and the acid–base properties) of surface treated activated carbons (ACs) using inverse gas chromatography. The surface energy and the acid–base characteristic of studied adsorbents are determined by the retention time using several non-polar and polar probes at 140 °C. It is observed that the dispersive surface energy dominates for all AC samples. The treatment of Maxsorb III with H2 exhibits the highest basicity due to lower oxygen content on the surface. The presented results express further insights and useful information in functionalizing the activated carbon for various industrial applications.
An Aggressive Large Epithelioid Hemangioendothelioma of the Anterior Mediastinum in a Young Woman

Hemangioendothelioma is a rare vascular tumor with involvement of the liver, brain, long bones, and lung. Among the 6 histological subtypes, epithelioid hemangioendothelioma (EHE) is the most aggressive. Its occurrence in the mediastinum is quite rare, and very few cases have been documented. The reported cases in the literature have described difficulties in the preoperative diagnosis due to the unusual histological appearance of the tumor. Immunohistochemistry remains the mainstay for a definitive diagnosis. Due to its low incidence, there is no standard treatment for mediastinal EHE, but curative resection is the preferred treatment option where possible, with chemotherapy used as an adjuvant treatment or in cases of widespread inoperable disease. The present case study describes an aggressive EHE occurring in an 18-year-old woman in the anterior mediastinum.
