The discovery of ferrocene1 heralded the advent of modern organometallic chemistry. Characterized by the π-coordination of a metal by one or two planar annulene anions, ferrocenes and their analogues2–4 exemplify the archetype of out-of-plane annulene
Full size image To analyze changes in spatial arrangement of the identified CSLs upon meayamycin treatment, we computed the pairwise spatial co-occurrence between all CSLs (Fig. 3f). Spatial co-occurrence12,32 captures the relative probability that two CSLs are found within a given distance inte...
Full size image 1. At the end, one gene encodes many proteins - more exactly, protein species - which are usually strongly interrelated based on their amino acid sequence, but which can, nonetheless, differ sometimes quite dramatically in chemical structure as a result of alternative splicing at...
DownLoad: Full-Size Img PowerPoint Bacterial community composition in Himalayan Griffons' rotten foods On the Qinghai-Tibetan Plateau, dead domesticated yaks, Tibetan sheep, Tibetan dogs, and horses make up the main diets of Himalayan Griffons (Additional file 2: Fig. S1). In addition to the...
Liquid water is a requirement for life on Earth. But on Saturn' s largest moon Titan, life might exist beyond the bounds of water-based chemistry, according to a new study by scientists at Cornell University.
He was the first to detect living sperm cells in animals and found blood cells. He found nematodes and rotifers, which are minute organisms. Van Leeuwenhoek soon became famous for his discoveries. Although he never attended a meeting, he was elected a full member of the Royal Society in ...

Full size image The presented method of synthesis uses an intermediate such as carbimidate “at its inception,” and this is its main advantage. Carbimidates were obtained from the corresponding carbonitriles in methanol in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and withou...
Full size image Among the UHTCs, ZrB2-SiC and HfB2-SiC have received the most attention because they uniquely combine high thermal conductivity, specific strength (σ > 460 MPa at T = 2500 °C,ρ = 5.5 g/cm3 83), and superior oxidation resistance ~1650 °C78,80,84. ...
