Single‐Particle FRET Probes Heterogeneity in the Ligand Shell of Colloidal Perovskite Quantum Dots
Advanced Materials, EarlyView.Single‐particle, single‐molecule Förster resonance energy transfer turns dye‐tagged ligands into nanorulers for the otherwise elusive organic shell of CsPbBr3 quantum dots. Distance variations within individual particles reveal pronounced local heterogeneity, while changes in the surrounding ligand chemistry shift the average dye–surface separation ...

Lead azide pre-explosive luminescence
, 2000 Pre-explosive luminescence of lead azide Pb(N3)2 in the range from 400 to 1000 nm was investigated both experimentally and theoretically. A theoretical investigation of the electron structure for a lead azide crystal was made using the.

Advanced Materials, EarlyView.Melt electrofibrillation (MEF) enables the fabrication of nanofibrillar PCL scaffolds with defined architectures that guide cellular alignment and retention during cartilage tissue engineering. Unlike conventional melt electrowriting, MEF consistently directs collagen type II‐rich extracellular matrix organization, providing a tunable platform to ...

Development of Cobinamide as Potential Antidote for Azide Poisoning [PDF]
, 2020 Sodium azide, referred to as “NaN3” or “azide” in this thesis, is a common pesticide, laboratory preservative, and propellent in vehicular airbags due to its explosive properties. Despite its practical utilities, azide is highly toxic.

Biological and Pharmaceutical Bulletin, 1995 Alkyl azides showed mutagenicity for S. typhimurium TA100 strain with S9 mix. However, no significant activity was observed for TA98 either with or without S9 mix or for TA100 without S9 mix. On the other hand, 3-azido-1,2-propanediol showed the enantioselective activity regardless of S9 mix.

Advanced Optical Materials, EarlyView.Ligand engineering enables precise control of emission in linear Cu(I) complexes by tuning donor–acceptor interactions between electron‐rich amines and π‐accepting mesoionic carbenes. Naphthyl‐substituted carbenes promote locally excited phosphorescence with vibronic structure, whereas electron‐rich amides combined with electron‐poor carbenes favor ...

An Improved Synthesis of Tetramethylammonium Azide [PDF]
, 2001 An improved synthesis of tetramethylammonium azide, N(Me)4+N3-, is presented. It involves a neutralization of tetramethylammonium hydroxide with sulfuric acid, followed by a metathetical reaction with sodium azide in methanol.

CD9+ B Cells Induce T Follicular Helper Cell Apoptosis to Regulate Germinal Center Regression
Advanced Science, EarlyView.A unique subset of CD9+ B cells regulates germinal center B (GC‐B) cell regression by inducing T follicular helper (Tfh) cell apoptosis through multiple signaling pathways, such as ALCAM‐CD6. FOXP1 plays a key role in GC‐B cell differentiation. These findings clarify mechanisms of GC degeneration and termination and offer potential targets for adenoid ...
