Summary: Measurements of ambient ion chemical composition provide direct insight into the most acidic and basic trace gases and their ion-molecule clusters. The use of the atmospheric pressure interface time-of-flight mass spectrometer (APi-ToF) combined with binPMF analysis allows for the temporal evolution of compounds important for new particle formation and growth to be studied. The results showed that negative ions consist of strong acids, organosulfates, and clusters derived from monoterpene and sesquiterpene oxidation, while positive ions consist of alkyl pyridines and amines.

Summary: This study found that under dark conditions, the aerosol yield can be significantly enhanced by nitrogen dioxide or sulfur dioxide within a certain ratio range of inorganic gases to biogenic volatile organic compounds, while ammonia showed a slight increase. The nitrogen- and sulfur-containing aerosol components were derived from nitrogen dioxide, ammonia, and sulfur dioxide, with organic nitrates and organosulfates identified in the experiments. These interactions among various compounds during the night could serve as a potential pathway for the formation of particulate nitrogen- and sulfur-containing organics in polluted regions with both anthropogenic and biogenic influences.

Summary: Laboratory experiments suggest acid-catalyzed aqueous-phase production can promote the formation of isoprene SOA, i.e., 2-methyltetrols. In this study, ambient observations and chemical measurements were used to investigate the importance of environmental factors in the formation of isoprene epoxydiols (IEPDX) SOA under atmospheric humidity conditions. The results show that photochemical processes dominate the formation of 2-methyltetrols in humid environments, and aerosol acidity has a limited influence on their formation. Additionally, high liquid water content reduces aerosol droplet acidity, thereby diminishing the enhancement of SOA formation.

Summary: The photosensitized transformation of organic chemicals is an important degradation mechanism in natural surface waters, aerosols, and water films on surfaces. Dissolved organic matter including humic-like substances (HS) can generate reactive species and promote the degradation of organic compounds through electron transfer reactions. Phthalate esters are used as probes to study the reactivity of HS irradiated with artificial sunlight. Isotope fractionation is used to elucidate reaction mechanisms. The correlation of isotopic fractions can be used diagnostically to determine photosensitized reactions in the environment and differentiate among different types of reactions.

Summary: Myeloproliferative neoplasms (MPN) are characterized by uncontrolled expansion of myeloid cells, disease-related mutations in certain driver-genes including JAK2, CALR, and MPL, and a substantial risk to progress to secondary acute myeloid leukemia (sAML). The phenotype of putative CD34(+)/CD38(-) stem cells and CD34(+)/CD38(+) progenitor cells in MPN were established. MPN stem cells display a unique phenotype, including cytokine receptors, immune checkpoint molecules, and other clinically relevant target antigens. The disease-initiating capacity of putative MPN stem cells was confirmed in NSGS mice. Phenotypic characterization of neoplastic stem cells in MPN and sAML should facilitate their enrichment and the development of stem cell-eradicating (curative) therapies.

Summary: Interference between single photons is crucial for various quantum optics experiments and applications in quantum technologies like communication and computation. Using lithium niobate on insulator (LNOI) as a new material platform for integrated quantum optics allows for operation at telecommunication wavelengths and integration of setups for improved stability, compactness, and scalability. By implementing a Hong-Ou-Mandel (HOM) interference in LNOI directional coupler, we achieve a high raw HOM visibility of (93.5 ± 0.7)%, establishing the foundation for advanced quantum experiments in LNOI.

Summary: This study presents a guided setup for single-mode squeezing on integrated titanium-indiffused periodically poled nonlinear resonators. By using single-mode fibers, a continuous-wave laser beam is delivered and the squeezed field is collected, with up to -3.17(9) dB of useful squeezing available in fibers. The generated squeezed light was applied in a fiber-based phase sensing experiment, showing a quantum enhancement in the signal-to-noise ratio of 0.35 dB. The investigation also reveals that photorefraction can cause system instabilities at high powers.

Summary: Under low NOx conditions, the atmospheric oxidation of isoprene produces hydroxy hydroperoxides (ISOPOOH) and further forms isoprene epoxy diols (IEPOX) as important SOA precursors, with highly oxidized ISOPOOH oxidation products potentially contributing equally to SOA. However, there are large uncertainties in the understanding of the respective atmospheric chemistry and its implications due to the lack of kinetic investigations on the phase transfer of ISOPOOH and its oxidation products. This study investigated the partitioning behavior of synthetic 1,2-ISOPOOH and its OH oxidation products in chamber experiments, and the results were implemented in a model study to evaluate the atmospheric relevance, which showed an increased SOA mass formation of 31% through the investigated ISOPOOH oxidation and phase transfer pathways.

Summary: The paper investigates the performance of lossy SU(1,1) interferometers for single-photon pairs and examines the information contained in single counts and coincidences at the output. The classical Fisher information (FI) of both single and coincidence events is derived and studied as a function of internal and external losses. It is found that, in the absence of external losses, the FI of coincidence events is always higher or equal to that of single events. However, with external losses, the FI of single events can surpass that of coincidences. Additionally, coincidence measurement can help mitigate the effect of internal losses in the absence of external losses. Finally, when internal losses are above 50%, SU(1,1) interferometers outperform classical SU(2) interferometers.

Summary: Unidentified daytime sources of halogen atoms in the atmosphere from photochemical halide oxidation in sea salt aerosols are important. It has been discovered that the photolysis of nitrate in aqueous chloride solutions not only generates Cl-2 and HOCl, but also nitryl chloride (ClNO2). This finding sheds light on a different mechanism of chloride oxidation involving nitrate, which could alter our understanding of daytime halogen cycling in the lower atmosphere.
