Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

Advanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

Deterioration behavior and mechanism of concrete under different exposure conditions of sulfate attack and carbonation

Case Studies in Construction Materials
This study systematically investigated the deterioration behavior of concrete under different erosion patterns, i.e., single sulfate attack, single carbonation, and alternating cycle of sulfate attack and carbonation (alternating cycle).

Depth‐dependent responses of soil organic carbon under nitrogen deposition [PDF]

Global Change Biology
AbstractEmerging evidence points out that the responses of soil organic carbon (SOC) to nitrogen (N) addition differ along the soil profile, highlighting the importance of synthesizing results from different soil layers. Here, using a global meta‐analysis, we found that N addition significantly enhanced topsoil (0–30 cm) SOC by 3.7% (±1.4%) in forests ...
