Acenes, the group of polycyclic aromatic hydrocarbons (PAHs) with linearly fused benzene rings, possess distinctive electronic properties with potential applicability in material science. Hexacene was the largest acene obtained and characterized in the last century, followed by heptacene in 2006. Since then, a race for obtaining the largest acene resulted in the development of several members of this family as well as diverse innovative synthetic strategies, from solid-state chemistry to the promising on-surface chemistry.

- - Hypothenar hammer syndrome is a rare condition caused by repetitive trauma to the hypothenar region of the hand, leading to vascular insufficiency.
- - Symptoms include cold intolerance, pain, paleness, and abnormal sensations (paresthesia) due to reduced blood flow (digital ischemia), which varies based on the ulnar artery blockage.
- - A 63-year-old man with bilateral Raynaud's phenomenon was treated with successful vascular repair surgery, highlighting the importance of recognizing hypothenar hammer syndrome as a reversible cause of Raynaud's symptoms.
The Dutos e Terminais do Centro Sul (DTCS) is one of the largest petroleum terminals of the South America located in the São Sebastião Channel (SSC) on the southeastern Brazilian coast. The aims of this study were to compare the sediment quality near the DTCS with that of several sites in the SSC region including the Araçá (AR) domestic sewage outfall and to assess the efficiency of the DTCS wastewater treatment plant. To achieve these goals, textural, geochemical, and living benthic foraminifera results were analyzed for the DTCS, AR, and SSC regions.
