Asymmetric Catalysis in Intramolecular Reactions of α-Diazoketones. Abstract: Carbon-hydrogen insertion reactions involve the insertion of a carbene‚ a neutral carbon atom or molecule with two unpaired valence electrons‚ into an unactivated carbon-hydrogen bond. This reaction produces many commercially valuable compounds. The reaction itself involves the use of diazocarbonyl compounds which contain an N2 ligand on a carbon alpha to a carbonyl. The reaction is thermodynamically favourable as it involves

MOLECULAR ELECTRONICS INTRODUCTION Molecular electronics (sometimes called moletronics) is a branch of applied physics which aims at using molecules as passive (e.g. resistive wires) or active (e.g. transistors) electronic components. The concept of molecular electronics has aroused much excitement both in science fiction and among scientists due to the prospect of size reduction in electronics offered by such minute components. It is an enticing alternative to extend Moore’s Law beyond the

Biology Notes 1.02 Sometimes a practice or belief claims to be science but does not follow the scientific method or cannot be proven reliable through experimentation. These practices are examples of pseudoscience‚ which literally means "fake science." Charms‚ astrology = stars‚ and phrenology= reading the bump on skull 1.03 * In the mid 1600s in the Netherlands‚ the scientist Antonie van Leeuwenhoek developed the first known microscope using a single magnifying lens. He was the first person
