In particular, they found that the molecular "backbone" of all 19 amino acids remained intact in sulfuric acid solutions ranging in concentration from 81% to 98%. "What is absolutely surprising is ...

Sulfuric acid (H2SO4), derived from SO2 ... highlight the importance of understanding sulfur chemistry at the molecular level. The process begins with SO2 dissolving in water to form sulfurous ...

They found that anodic porous alumina (APA) surfaces prepared using electrochemistry in concentrated sulfuric acid had unprecedented resistance to bacterial growth, but did not hamper cell cultures.
