Summary: We have developed a novel phase-space method to dynamically monitor quantum coherence in polariton condensates. Our approach allows us to quantify complex decoherence mechanisms and provides a stable system for long-term coherence. By reconstructing phase-space functions from homodyne detection data, we have demonstrated the potential of using quantum coherence for information processing up to the nanosecond regime.

Summary: This article introduces a framework for entanglement characterization using time-resolved single-photon counting with measurement operators defined in the time domain. The approach is discussed in relation to photonic tomography, with considerations for timing uncertainty and Poisson noise on photon counts. Numerical testing on qubit quantum tomography and accuracy evaluation for polarization-entangled photon pairs are presented, quantified by figures of merit and plotted against time uncertainty.

Summary: Determining the rate of rotation of molecules using fluorescence anisotropy decay curves is a powerful method in biological applications. However, the nonlinearity in the photon counting rate on fluorescence intensity flux can cause distortions in the determination of fluorescence anisotropy lifetime and asymptotic fluorescence anisotropy. This study investigated the effects of this nonlinearity and its dependence on temperature, as well as its manifestation in the case of photobleaching of the fluorophores.

Summary: A paper-based cell-counting method utilizing a blocking competition strategy was developed, along with a time-resolved fluorescence-blocking competitive lateral flow immunoassay (TRF-BCLFIA) for CD8 cell counting. This approach can provide an accurate CD8 cell count for whole-blood samples within 30 minutes and shows potential as a cost-effective alternative in community clinics, small hospitals, and low-resource regions where standard flow cytometry-based tools are not readily available.

Summary: We suggest using a femtosecond X-ray pulse to trigger Resonant Auger scattering (RAS) in a distorted molecule, which provides information on the core-valence electronic transition and impresses a rich fingerprint of the electronic structure and nuclear configuration. By controlling the amount of molecular distortion with varied time delay, the RAS measurements imprint both their electronic structures and changing geometries. This work showcases a new alternative pump-probe technique for mapping the core and valence dynamics with ultrashort X-ray probe pulses.

Summary: A novel time-gated SPAD receiver is proposed to improve the performance of optical wireless communication and mitigate ISI effects caused by dead time. The SPAD operates in gated mode with defined time intervals for activation and deactivation, and the gate-ON time interval can be optimized for best BER performance. Performance analysis shows that the time-gated SPAD receiver outperforms traditional free-running receivers in terms of BER, data rate performance, and tolerance to background light.

Summary: Descloux et al. introduce a parameter-free modified histogram rendering method for resolution estimation in localization microscopy datasets, accurately conveying localization information and depending on precision and density of localizations. Localization microscopy is a super-resolution imaging technique that relies on spatial and temporal separation of blinking fluorescent emitters, achieving sub-diffraction precision bounded by photon emission and sensor noise. The proposed bilinear histogram rendering pipeline avoids biases from Gaussian or standard rendering, demonstrating resolution estimation dependence on localization density and precision.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
