Full Spectrum Electrochromic WO₃ Mechanism and Optical Modulation via Ex Situ Spectroscopic Ellipsometry: Effect of Li⁺ Surface Permeation by Buyue Zhang, Jintao Wang, Shuhui Jiang, Meng Yuan, Xinyu Chen

“…However, most previous work focuses on the absorption or transmission spectra of materials, rather than the optical parameters evolution in full spectrum in the electrochromic processes. Herein, we developed a systematic protocol of ex situ methods to clarify the evolutions of subtle structure changes, Raman vibration modes, and optical parameters of WO₃ thin films in electrochromic processes as stimulated by dosage-dependent Li⁺ insertion. …”

Infrared Drying of Seeds in a Fluidized Bed by Ya. P. Lobachevsky, S. A. Pavlov

“…One of them is combined infrared drying. Combined modes of IR drying have a number of advantages over convection drying - quick heating of the particles ensures shortened process time, and the combination of diffusion and thermal diffusion processes facilitates the transfer of moisture from the grain mass center to the periphery, which reduces the specific heat consumption of a drying process. …”

Study on flexural behavior of CO2 cured recycled coarse aggregate concrete steel bar trusses composite slab by Yueqing Gao, Sijie Shen, Ke Ye, Zeshen Li, Wei Wang, Jingyi Lu, Shaodan Hou, Yangyang Yin, Chaofeng Liang

“…The results indicated that: (1) The mechanical properties of RAC after carbonation were significantly improved, and the concrete prepared by the combined method of aggregate carbonation and overall specimen carbonation showed the highest strength. (2) The stress-strain constitutive models of RAC under different carbonation methods were built according to the experimental results. (3) The failure modes of the carbonated concrete SBTCSs were basically consistent and the precast layer and the cast-in-situ layer deformed coordinately during the loading process. (4) The SBTCS prepared by the combined method of aggregate carbonation and overall specimen carbonation showed the best bending performance, and the ultimate load bearing capacity increased by 16.2 % compared to the SBTCS made by non-carbonated RAC. (5) The load-displacement curves and damage contours of the SBTCSs obtained from the numerical analysis were in good agreement with the experimental results, and the maximum deviation between the simulated ultimate load and the experimental value was 8.8 %.…”

Weakened large-scale surface heat flux feedback at midlatitudes under global warming by Zhiqiao Wang, Zhao Jing, Fengfei Song

“…Abstract The surface heat flux feedback, which refers to the response of surface heat flux anomaly to the underlying sea surface temperature anomaly (SSTA), is one of the key processes in air-sea interaction. It plays an important role in regulating various aspects of the climate system, ranging from local SSTA persistence to the global overturning circulation and major climate modes. …”
