Attachment of Silicon quantum dots (Si QDs) onto starch via sol-gel controlled covalent bonding to form hybrid starch particles was developed to modulate the optical, physical, and mechanical features of starch. Fabricated Si QDs chemically interacted with –OH side groups due to the sol-gel reactions on the starch molecules providing a detectable new molecular bonding to result in fluorescent emission. The produced structures formed nonlinear morphological orientations that provide a nanocomposite material platform for a facile molecular marking in daily applications.

Human coronavirus OC43 (HCoV-OC43) causes severe respiratory tract illness in humans. In the present study, we carried out 100 ns molecular dynamics (MD) simulations to investigate the conformational dynamics of HCoV-OC43 spike (S) glycoprotein complexes with sialic acid (SIA) analogs. The binding affinity between the HCoV-OC43 S and SIA analogs is analyzed using NAMD and MM-PBSA binding free energy calculation. It is concluded from the results of NAMD and MM/PBSA that the order of binding specificity toward HCoV-OC43 S is 9-O-Ac-Sia > SIA > Neu5Gc > zanamivir > Neu5Ac2en.

The rise of carbon dioxide (CO2) in atmosphere is considered as a major cause of global warming. Therefore, CO2 utilization has attracted increasing attention. Among those, using CO2 as C1-feedstock for “value carbon” in advanced chemicals provides a solution. Here, we show an acetylglucose-based imidazolium salt for Cu-catalyzed cyclization of propargylic amines and CO2 with an excellent turnover frequency value of 400 h−1. To the best of our knowledge, it is the first example of acetylglucose-based imidazolium salts for a noble-metal-free Cu catalytic system for the cyclization of propargylic amines and CO2.

2-Benzofuranyl C-glycosides were synthesized in good to excellent yields by one-pot cascade reaction of terminal sugar alkynes and substituted 2-iodophenols. The products have wide structural diversity and potential biological activity. This new synthetic method is general, mild, and efficient. Thirty-seven examples have been given. The structurally diverse terminal sugar alkynes included pyranosides, furanosides, and acyclic sugars with sensitive and bulky protecting groups. The substituted 2-iodophenols contained electron-donating, electron-withdrawing, and electron-neutral substituents. The mechanism for the formation of the products has been proposed.
