Safe by Design Flow Technology for Diazoacetonitrile Generation and Direct Conversion to Pyrazoles

ChemistryOpen
Diazo compounds enable short and efficient synthetic routes but their broader adoption is limited by hazards associated with their preparation, storage, and handling. Here, a safe by design continuous flow process is presented in which diazoacetonitrile (

Theoretical design and exploration of novel high energy density materials based on silicon

, 2017
Si-based high energy density materials (HEDMs) have been theoretically studied based on density functional theory and ab initio molecular dynamics simulation. These HEDM compounds have a unique fused-heterocyclic structure centered at Si.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
