Summary: Third-generation solar cells, such as dye-sensitized solar cells and quantum dot-sensitized solar cells, require counter electrodes (CEs) for their functionality. Platinum-based CEs are dominant but expensive, thus alternative materials like transition metal chalcogenides (TMCs) and transition metal dichalcogenides (TMDs) have been explored. This study provides a comprehensive review of the major components and working principles of these solar cells, and evaluates the performance efficiencies resulting from TMS-based CEs compared to Pt-based CEs.

Summary: A low cost H3PW12O40 (PW12)/CoS2 complex was prepared and used as a counter electrode to combine with sandwich quantum dot sensitized solar cells, showing significantly higher photoelectric conversion efficiency compared to undoped CoS2 counter electrodes. The introduction of PW12 led to changes in the structure of CoS2 nanoparticles and decreased the work function, contributing to the increased active sites and improved efficiency. This study demonstrates the potential of POMs in optimizing CE materials and enhancing the performance of QDSSCs, laying the foundation for further research.

Summary: This work presents a facile route for fabricating bimetallic (tungsten and molybdenum)-reduced graphene oxide nanocomposites as a promising electrocatalyst for dye-sensitized solar cells. The properties of the nanocomposites were investigated using various characterization tools, and their photovoltaic and electrochemical performance were evaluated. The bimetallic nanocomposites exhibited comparable power conversion efficiency to traditional materials and could be a feasible alternative with reduced production cost.

Summary: In this paper, a new piezoelectric-actuated biaxial compliant microgripper with long strokes is proposed for automatically gripping and rolling tiny rigid objects. The microgripper has been optimized structurally and its performance has been simulated using finite element analysis. Experimental results show that the developed microgripper has the capability to grasp and roll tiny rigid objects, making it promising for precision micromanipulation tasks such as optical fiber alignment.

Summary: In this article, we propose a novel test based on an aggregation of the marginal cumulative covariances to accommodate heteroscedasticity and high dimensionality in high-dimensional data. Our proposed test statistic is scale-invariance, tuning-free, and easy to implement, with established asymptotic normality under the null hypothesis. We find that our proposed test is much more powerful than existing competitors for covariates with heterogeneous variances, even under high-dimensional linear models, while maintaining high efficiency for homoscedastic covariates.

Summary: In this paper, a generalized reaching-law-based discrete-time integral sliding-mode controller is designed to achieve high output tracking accuracy and avoid significant control efforts for both matched and mismatched disturbances. By synthesizing a disturbance-related integral term based on disturbance decomposition, the proposed sliding surface differs from existing integral sliding surfaces and is crucial for disturbance attenuation. The proposed reaching law introduces an adaptive exponential term into the control gains, which allows for the integration of conventional RL-based DISMC and EC-based DISMC.

Summary: B-spline curve approximation with tool tip position adjustment is proposed to reduce the maximum curve curvature and improve machining efficiency without exceeding tolerance in CNC machining. Toolpaths are divided into subdivisions based on discrete curvature, and tool tip positions are adjusted to minimize maximum discrete curvature. The improved ELSPIA method fits the adjusted toolpaths and lowers chord errors by searching appropriate foot point parameters.

Summary: Superconducting photodetection offers wide spectral coverage and single photon sensitivity, but the detection efficiency is low in the longer wavelength infrared range. By using a superconducting metamaterial, we achieved nearly perfect absorption at dual color infrared wavelengths and enhanced light coupling efficiency. Our infrared detector demonstrated peak responsivity of 1.2 x 106 V/W and 3.2 x 106 V/W at two resonant frequencies, significantly higher than the non-resonant frequency. This work provides a way to improve the sensitivity of superconducting photodetectors in the infrared range.

Summary: A modified screen-printed electrode based on ZIF-8, Ag NPs, and ErGO was developed for dopamine detection. The synthesized ErGO/Ag-ZIF-8 composites maintained the structure of ZIF-8. The oxidation current of dopamine increased linearly in the range of 0.1-200 mu M with a detection limit of 0.03 mu M (S/N=3). The sensor exhibited good reproducibility and selectivity, and it was successfully applied for dopamine detection in goat serum with satisfactory recovery range.
