Dependence of Energy Thresholds on Laser Radiation Wavelength in Initiation of Heavy Metal Azides [PDF]
The behavior of silver and lead azides (scaly and threadlike crystals, and compacted powders) in initiation of explosive decomposition by laser pulsed radiation has been investigated. Initiation energy thresholds in irradiation at wavelengths of 1064 nm, 532 nm, 354.7 nm, 266 nm corresponding to four laser radiation harmonics have been measured ...

End-group functionalization of poly(2-oxazoline)s using methyl bromoacetate as initiator followed by direct amidation [PDF]
Poly(2-alkyl/aryl-2-oxazoline)s (PAOx) are an alluring class of polymers for many applications due to the broad chemical diversity that is accessible for these polymers by simply changing the initiator, terminating agent and the monomer(s) used in their ...

Rice seeds of the temperate japonica cultivar Kitaake were mutagenized with sodium azide alone and in combination with methyl nitrosourea. Using the reduced representation sequencing method Restriction Enzyme Sequence Comparative Analysis (RESCAN), the mutation densities, types and local sequence context were determined in the resulting M2 generation ...

2D organic semiconductors are widely believed to have uniformly active surfaces. This study reveals that their basal planes can be pseudo‐inert due to anisotropic exciton migration. By inducing exciton self‐trapping through dimensional reduction, these inert planes are activated, boosting hydrogen peroxide production by over 350%. The work uncovers key

Reaction of Sodium Azide with 1,1'–Dicyclohexenyl–Diepoxides [PDF]
Nucleophilic ring opening of dl and meso 1,1¢- dicyclohexenyl diepoxides by sodium azide in dioxane and aqueous alcoholic medium give the corresponding azidoalcohols.

Methionine 129 variant of human prion protein oligomerizes more rapidly than the valine 129 variant - Implications for disease susceptibility to Creutzfeldt-Jakob disease [PDF]
The human PrP gene (PRNP) has two common alleles that encode either methionine or valine at codon 129. This polymorphism modulates disease susceptibility and phenotype of human transmissible spongiform encyphalopathies, but the molecular mechanism by ...

Controlled functionalization of graphene oxide with sodium azide
We present the first example of azide functionalization on the surface of graphene oxide (GO), which preserves thermally unstable groups in GO through the mild reaction with sodium azide in solids. Experimental evidence, by (15)N solid-state NMR and other spectroscopic methods, indicates the substitution of organosulfate with azide anions as the ...

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