Summary: In this study, the diffusion dynamics in polymer micro-objects are detected in situ by utilizing optical whispering-gallery mode resonances. The interactions between solvent molecules and polymer microspheres, such as sorption, diffusion, and swelling, are quantitatively analyzed through mode tracking. A turning point of mode response is observed when diffusion exceeds the sub-wavelength-thick outermost layer and starts penetrating the inner core. The estimated solubility in the glassy polymer agrees with the predicted value using Flory-Huggins theory. Besides, non-Fickian contribution is analyzed in the glassy polymer-penetrant system. This work represents a high-precision and label-free approach to describing characteristics in diffusion dynamics.

Summary: In this article, a rapid thermal process is proposed to manufacture piezoresistance for improved performance of piezoresistive devices. An absolute piezoresistive pressure sensor is prepared by anodic bonding between a silicon film and glass with a cavity, resulting in a compact size of 1.0 x 1.0 x 0.513 mm. The piezoresistance arrangement is optimized using the finite element method, and the feasibility of Ti as an oxygen absorber in the anodic bonding process is verified through diaphragm deformation measurement. The pressure sensor prepared using the rapid thermal annealing (RTP) process exhibits an output voltage of 91.6 mV, nonlinearity of 0.14% FSO, temperature coefficient of resistance (TCR) of 571 ppm/degrees C, and temperature coefficient of sensitivity (TCS) of -1676 ppm/degrees C within the pressure range of 0-200 kPa. Compared to the pressure sensor prepared by the common piezoresistive process, the designed sensor shows a reduced TCR by 73% and TCS by 24%, while providing high output voltage, low TCR and TCS, and a small size.

Summary: In this paper, a Ga2O3-based pressure sensor is introduced using the technique of metalorganic chemical vapor deposition thin film growth. Although Ga2O3 is an important semiconductor material for functional electronics and optoelectronics, there has been limited research on Ga2O3-based pressure sensors. However, this study demonstrates that the fabricated Ga2O3-based pressure sensor exhibits good sensing performance for different pressures. The sensor shows an increase in current by two orders of magnitude under a pressure of 5 kPa. Additionally, the response/release times were measured under different pressures ranging from 1 to 20 kPa. This work provides a potential method for constructing smart pressure sensors based on functional Ga2O3.

Summary: In this work, a double design host and guest strategy is proposed to enhance the electrochemical properties of sulfur electrodes in sodium ion storage. The V2O3 adsorbent immobilizes sulfur species, while the selenium dopant improves the electronic conductivity and redox conversion of sulfur cathodes. The synergistic effect between the V2O3 adsorbent and selenium dopant inhibits the shuttle effect and improves the redox kinetics, resulting in greatly enhanced Na-ion storage properties of sulfur cathodes. The as-designed sulfur cathode exhibits excellent rate capability of 663 mA h g(-1) at 2.0 A g(-1) and exceptional cyclability of 405 mA h g(-1) over 700 cycles at 1.0 A g(-1).
