Summary: This paper investigates the strain effects on the energy barrier of proton diffusion in Y-doped BaCeO3 and BaZrO3 through detailed density functional theory calculations. The energy barrier of proton rotation decreases under tensile strain. However, for intra-octahedral proton transfer, the energy barrier decreases under tensile strain, while for inter-octahedral proton transfer, the energy barrier increases under tensile strain. The opposite strain effects observed in BCY and BZY during intra-octahedral proton transfer are attributed to the opposite bond order change of the hydrogen bond. Overall, this study explores the potential to tune the energy barrier of proton transport in perovskite oxide through strain engineering and design novel proton conductors.

Summary: Oxygen vacancy engineering via calcium-doping is proposed and validated to improve proton conduction in proton conducting oxides. The presence of more oxygen vacancies and the tailored position of vacancies accelerate proton diffusion and increase proton concentration. The doped compound BZCa1Y2 exhibits higher proton concentration, ionic conductivity, and proton diffusion coefficient compared to BZY2.

Summary: CdS thin films were prepared by chemical bath deposition (CBD), and Sb2S3-y Se (y) thin films were prepared by a hydrothermal method. The quality of CdS thin films as the electron transport layer was evaluated in solar cells with the architecture of FTO/CdS/Sb2S3-y Se (y)/spiro-OMeTAD/Au. A precise preparation strategy, involving adjusting the thickness of CdS thin films prepared by CBD and changing the concentration of the CdCl2 methanol solution in the post-treatment process, was proposed for the first time. The strategy allowed for the successful production of a compact and full-coverage CdS thin film with a thickness of 40 nm and achieved an optimal power conversion efficiency of 8.46%.

Summary: Theoretical reevaluation of proton diffusivity in yttrium-doped barium zirconate (Y-doped BaZrO3) with realistic dopant configurations showed that proton diffusion under realistic Y configurations is higher than that in random configurations due to fewer trap sites with deep potential wells. Additionally, the effects of proton-proton interaction and the abundance of preferential conduction pathways were found to be relatively minor factors in comparison to the trap site effect in determining proton diffusivity dependence on Y configurations.

Summary: Two-step mixed atmosphere annealing enhances the stability of nitrogen-doped ITO thin films at high temperatures, with the N-2-air ITON thin film showing better stability compared to N-2-vacuum ITON thin film. This is attributed to the more complete repair of oxygen deficiencies during the second-step annealing in air.

Summary: In this study, a lysosome-targeting buffering fluorogenic probe (Lyso-BFP) was designed and synthesized, demonstrating excellent photostability, pH specificity, and responsiveness to lysosomal acidification in living cells. The performance of Lyso-BFP in pH sensing was attributed to the inhibition of the photo-induced electron transfer process. Lyso-BFP allowed for wash-free imaging and long-term real-time monitoring of lysosome pH changes based on its off-on fluorescence behavior and buffer strategy.

Summary: This study developed a high-performance gas sensor for formaldehyde detection by modifying ZnSnO3 with ZnO QDs and SnO2 QDs. The modified sensor showed improved sensing response and lower working temperature. The presence of ZnO QDs formed rich heterojunctions, increased surface area, and provided oxygen deficiency for formaldehyde sensing reaction, thus enhancing the sensor performance. This research provides an alternative method to enhance the sensing properties of MOS by QDs modification.

Summary: The molecular subtype of breast cancer guides treatment and drug selection. Invasive tests can promote cancer cell metastasis, so the development of high-performance, low-cost diagnostic tools for cancer prognosis is crucial. Liquid biopsy techniques enable noninvasive, real-time, dynamic, multicomponent, quantitative, and long-term observations at the cellular, genetic, and molecular levels. A Cu-Zr metal-organic framework (MOF) nanoenzyme with monatomic Cu attachment has been synthesized and proven to have high catalytic performance. The sensor constructed using this nanoenzyme shows potential for accurate classification of breast cancer serum samples.

Summary: This study presents a method to fabricate independently functioning microneedle (MN) electrodes with narrow intervals for high precision electrochemical sensing. The optimized mixture of photocurable polymer and single-wall carbon nanotubes was used to mold single composite MNs, which were then attached to pre-patterned electrodes. Plasma etching and electropolymerization were performed to enhance the electrochemical activity, and Prussian blue and glucose oxidase were electrodeposited on the MNs for glucose detection. The MN electrodes showed good sensitivity and linearity, and the feasibility of glucose detection was demonstrated in an in vivo mouse study.
