A Hong Kong University of Science and Technology (HKUST) research team has developed a catalytic enantioselective type II [5 + 2] cycloaddition method to address the challenges of synthesizing chiral ...

Polycyclic aromatic compounds, characterised by fused aromatic rings, underpin advances in organic electronics, photonics and catalysis. Synthetic approaches broadly divide into bottom-up ...

Spiroaspertrione A is a complex polycyclic compound naturally produced by the fungus Aspergillus sp. TJ23. First isolated in 2017, it quickly drew scientific attention for its promising ability to ...

A Hong Kong University of Science and Technology (HKUST) research team led by Prof. SUN Jianwei and Prof. LIN Zhenyang from the Department of Chemistry has developed a catalytic enantioselective type ...

Worse, these contaminated particles pose a double risk, researchers said – first when they are airborne, and again when they ...

Polycyclic aromatic hydrocarbons are an important class of fused-ring natural compounds that are under fire for being toxic. Evidence suggests PAHs, which occur naturally in oil (including edible oils ...

The South Korean researchers found a way to test common foods for cancer-causing compounds ...

Whenever an organic matter is burned, such as in a wildfire, a power plant, a car's exhaust, or in daily cooking, the combustion releases polycyclic aromatic hydrocarbons (PAHs) - a class of ...

Complex polycylic structures are found in nearly every biosynthetic class of natural products. In particular, an amazing range of rigid densely functionalized polycylic compounds are formed from ...

Making children laugh can build deep emotional connections and soothe their nervous systems, making them more resilient and open to new ideas, says a leading child development expert. Dr. Jacqueline ...
