Summary: Dye-Sensitized Solar Cells (DSSCs), also known as Gratzel cells, are a third-generation photovoltaic technology that shows promise in terms of simplicity, economic viability, and high power conversion efficiency. The use of zinc oxide (ZnO) coupled with graphene as the photoelectrode enhances charge transfer and reduces electron-hole recombination, leading to improved performance. This review examines the feasibility and performance enhancement of ZnO/graphene nanocomposite and its derivatives as photoelectrodes for DSSCs, including their structural features, optical properties, electron transport, and dye interaction. The limitations and potential solutions for ZnO/graphene derivatives as photoelectrodes are also discussed. The ZnO/graphene-based photovoltaic cells have demonstrated an efficiency of up to 11.5% with different dyes and electrolytes. Furthermore, the recent progress of ZnO/graphene as a viable alternative to titanium dioxide (TiO2) is thoroughly reviewed.

Summary: The photovoltaic performance of dye-sensitized solar cells (DSSCs) based on TiO2 and BaTiO3 was improved by hydrothermal treatment of the porous TiO2 film. The structural, optical, and morphological properties of the deposited titanium dioxide and barium titanate film were studied. The efficiency of the DSSC increased threefold after converting the porous titanium dioxide into barium titanate. The lifetime was longer in the case of using barium titanate, while the ideality factor was higher when using titanium dioxide.

Summary: Two series of nanocomposite photoanodes were synthesized for DSSCs, one with Samarium Titanate/TiO2 nanocomposites and the other with Gd2O3-impregnated SmTiO3/TiO2 nanocomposites. The research found that the TiO2+4%SmTiO3 in the first series had the highest power conversion efficiency (PCE) of 5.31 +/- 0.03%. In the second series, the DSSCs with TiO2+4%SmTiO3/Gd2O3 and 5% Gd2O3 had the highest PCE of 8.08 +/- 0.06%. The improved photovoltaic efficiency was attributed to enhanced IPCE, dye loading, charge transfer resistance, capacitance, and visible photons absorption.

Summary: Isolation of circulating tumor cells (CTCs) from patients is challenging due to their rarity. In this study, a method combining nanostructures with a photocurable hydrogel (CSMA) was presented for single-cell recovery. The gelatin nanoparticles (Gnps) were synthesized and modified on a flat glass substrate for specific capture of CTCs. Selected cells were encapsulated with CSMA using a 405 nm laser, while unselected cells were removed. The isolated CTCs were analyzed using nucleic acid detection, and the results demonstrated the platform's biocompatibility and successful isolation of selected cells. This light-induced hydrogel responsive platform holds potential for clinical applications.

Summary: Circulating tumor cells (CTCs) are cancer cells that circulate in the blood after breaking away from solid tumors and play a crucial role in the establishment of distant metastasis. Detecting and analyzing CTCs, as a new form of liquid biopsy, provide valuable information for cancer diagnosis, especially in monitoring disease status in a timely manner and avoiding the limitations of invasive tissue biopsy. Recent research has explored the use of nanomaterial-based platforms to efficiently enrich and sensitively detect CTCs. These platforms hold promise for precise profiling and analysis of CTCs.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
