We constrain the Cardassian expansion models from the latest observations,including the updated Gamma-ray bursts (GRBs),which are calibrated using a cosmology i
Aromatic aldehydes undergo crossed-aldol condensation with ketones in the presence of catalytic amount of sulfamic acid (SA) to afford the corresponding α,β-u
A ligand is a small molecule bind to several residues of a receptor. We adapt the concept of molecular path for effective ligand search with its contacting resi
Magnetic anion exchange resin (MD-1) was prepared from quaternization of magnetic copolymeric resin (glycidyl methacry-late-co-divinylbenzene). For comparison,
