The novel double strained alkyne 3 has been prepared and evaluated in strain-promoted azide-alkyne cycloaddition reactions with azides.The x-ray crystallographic structure of 3, which was prepared in one step from 1,1-biphenyl-2,2,6,6-tetrol 4, reveals the strained nature of the alkynes.Dialkyne 3 undergoes cycloaddition reactions with a number of azides, giving mixtures of.
Due to the high chloride ion concentration in marine environments, chloride ions can penetrate into concrete, along with the transportation of water molecules, and thus, cause rebar corrosion.This is an important reason for the decrease in the concrete durability.In this paper, by means of the solgel synthesis method, a silane emulsion, a silane compound emulsion, and silane compound gel.
The production of waste bottom ash ba from coal power plants in the west coast of south korea has been a serious environmental problem to resolve.In this investigation, waste ba was recycled to prepare bapolypropylene and bapolyethylene composites, and their mechanical properties were compared.The hazardous metal content in the waste ba was minimal, and the waste ba was not contaminated.
Neurovascular coupling, the close spatial and temporal relationship between neural activity and hemodynamics, is disrupted in pathological brain states.To understand the altered neurovascular relationship in brain disorders, longitudinal, simultaneous mapping of neural activity and hemodynamics is critical yet challenging to achieve.Here, we use a multimodal neural platform in a mouse model.
