Rapid and Scalable Halosulfonylation of Strain‐Release Reagents**

open access: yesAngewandte Chemie, Volume 135, Issue 3, January 16, 2023., 2023
A one‐pot halosulfonylation of strained hydrocarbons is described that proceeds under practical, scalable and mild conditions. Sulfonyl halides featuring aryl, heteroaryl and alkyl substituents are generated in situ from sulfinate salts and convenient halogen atom sources. This chemistry enables the synthesis of an array of halogen/sulfonyl‐substituted

Controlling Frost Propagation on Polymeric Surfaces Using SI‐ATRP Chemical Micropatterning

open access: yesAdvanced Materials Interfaces, EarlyView.
Local wettability differences on the polymeric substrates grafted with hydrophilic stripes are linked to local variations in the presence and state of molecular water layer (MWL). The localized MWL results in fast‐propagating freezing events on the hydrophilic stripes followed by slower freezing propagation across the more hydrophobic substrate, thus ...

Continuous multistep synthesis of 2-(azidomethyl)oxazoles

open access: yesBeilstein Journal of Organic Chemistry, 2018
An efficient three-step protocol was developed to produce 2-(azidomethyl)oxazoles from vinyl azides in a continuous-flow process. The general synthetic strategy involves a thermolysis of vinyl azides to generate azirines, which react with bromoacetyl ...

Mechanical deformation of monocytic THP-1 cells : occurrence of two seqential phases with differential sensitivity to metabolic inhibitors [PDF]

open access: yesExperimental Biology Online - EBO 2 (1997) 5, 2007
Blood leukocytes can exhibit extensive morphological changes during their passage through small capillary vessels. The human monocytic THP-1 cell line was used to explore the metabolic dependence of these shape changes. Cells were aspirated into micropipettes for determination of the rate of protrusion formation.

Extracellular Vesicle Crosslinkers Constructing Hydrogels with Stress‐Relaxation and Bioactive Protein Modification

open access: yesAdvanced Materials Interfaces, EarlyView.
Extracellular vesicles (EVs) are functionalized and used as crosslinkers to construct hydrogels, compatible with common crosslinking chemistries in biomaterial scaffolds. EV crosslinkers provided stress relaxation properties, promoting cell growth. They also enabled efficient protein delivery while maintaining biological activity, as VEGF‐loaded EV ...

Synthesis of 6-Amino-5-cyano-1,4-disubstituted-2(1H)-Pyrimidinones via Copper-(I)-catalyzed Alkyne-azide ‘Click Chemistry’ and Their Reactivity

open access: yesMolecules, 2010
In this paper we present the room temperature synthesis of a novel serie of 1,4-disubstituted-1,2,3-triazoles 4a-l by employing the (3 + 2) cycloaddition reaction of pyrimidinones containing alkyne functions with different model azides in the presence of

Compound oxidized styrylphosphine [PDF]

open access: yes, 1979
A process is described for preparing flame resistant, nontoxic vinyl polymers which contain phosphazene groups and which do not emit any toxic or corrosive products when they are oxidatively degraded.
