The relative change in measured ??(N2O5) as a function of particle nitrate loading appears to be consistent with expectations based on laboratory data, providing direct support for the atmospheric importance of the so-called "nitrate effect".doi:10.5194/acp-12-2959-2012...

N2O5is selectively adsorbed to the liquid–vapor interface and weakly solvated. Accommodation into bulk water occurs slowly, competing with evaporation upon adsorption from gas phase. Leveraging the quantitative accuracy of the model, we parameterize and solve a reaction–diffusion equation to determine ...
Third, the so-called double-wave method (DWM) associated with the Sawyer-Tower circuit was used to measure the polarization-electric field hysteresis loop of these materials31. The obtained second hysteresis loops exhibit clear double-loop shape, suggesting possi- ble ferrielectric (FIE) or ...
While the resonant intensity at the Mn L2,3 edges reflects the magnetic order parameter, the resonant scattering at the O K edge is found to be directly related to the macroscopic ferroelectric polarization. The latter observation reveals the important role of the spin-dependent Mn-O hybridization...
Evinacumab, the active substance in Evkeeza, attaches to a protein in the body called ANGPTL3 and blocks its effects. ANGPTL3 is involved in controlling cholesterol levels and blocking its effect reduces the level of cholesterol in the blood. Evkeeza is delivered via an infusion every month (...
The endurance of the RRAM can achieve 105 times and its retention time can also achieve 10000 seconds under high temperature (850C) thermal stress.For the DyMn2O5-based RRAM, the current-voltage characteristics possess aspecial phenomenon which is called Negative Differential Resistance (NDR). In ...
We have observed successive dielectric and magnetic phase transitions, which concomitantly takes place and a so-called "multiferroics" is realized. In this system, the ferroelectricity is magnetically induced and the commensurate magnetism is indispensable to produce a spontaneous electric polarization. The...
A systematic study of linear and nonlinear dielectric susceptibilities temperature and frequency dependences was conducted. A composition-induced crossover in nonlinear dielectric susceptibility was detected. The so-called scaled nonlinear susceptibility, a(3), was obtained from experimental values of the ...
Due to its unique structural and electronic properties, under certain external stimuli, the high-temperatureRMn2O5can develops the so-called electronic ferroelectricity through charge transition/transfer between Mn4+and Mn3+sites. In addition, the predicted ferroelectric polarization in the monoclinicPm/...
