Low-Dimensional Metal-Alkynyls: On-Surface Synthesis and Properties.

Metal-alkynyls, an emerging class of functional metal-organic materials, have attracted widespread attention due to their fascinating properties and multifaceted potential applications, such as luminescence, nonlinear optics, liquid crystals, and catalysis. Despite considerable effort toward their synthesis, precise construction of complex metal-alkynyl structures with a high selectivity remains a great challenge. The rise of on-surface chemistry not only offers a route to realizing controlled synthesis of low-dimensional (LD) metal-alkynyls but also provides an opportunity for their in-depth investigations with advanced surface characterization techniques such as scanning tunneling microscopy.

Environmentally relevant levels of BPA and NOR disturb early skeletal development in zebrafish.

Bisphenol A (BPA) and fluoroquinolone antibiotics (FQs) have been detected frequently in aquatic environments. Studies have shown that high levels of BPA and FQs exposure have adverse effects on chondrogenesis in young terrestrial vertebrates. However, little is known about their combined toxicity to bone metabolism.
