Ion Migration in Organometal Trihalide Perovskite and Its Impact on Photovoltaic Efficiency and Stability
Creators: name: Huang, Jinsong

Publisher: name: American Chemical Society
Year: 2016

description: Organometal trihalide perovskites (OTPs) are
emerging as very promising photovoltaic materials because the
power conversion efficiency (PCE) of OTP solar cells quickly rises
and now rivals with that of single crystal silicon solar cells after only
five-years research. Their prospects to replace silicon photovoltaics
to reduce the cost of renewable clean energy are boosted by the lowtemperature
solution processing as well as the very low-cost raw
materials and relative insensitivity to defects. The flexibility,
semitransparency, and vivid colors of perovskite solar cells are
attractive for niche applications such as built-in photovoltaics and
portable lightweight chargers. However, the low stability of current
hybrid perovskite solar cells remains a serious issue to be solved
before their broad application. Among all those factors that affect the
stability of perovskite solar cells, ion migration in OTPs may be
intrinsic and cannot be taken away by device encapsulation.
The presence of ion migration has received broad attention after the report of photocurrent hysteresis in OTP based solar cells.
As suggested by much direct and indirect experimental evidence, the ion migration is speculated to be the origin or an important
contributing factor for many observed unusual phenomenon in OTP materials and devices, such as current−voltage hysteresis,
switchable photovoltaic effect, giant dielectric constant, diminished transistor behavior at room temperature, photoinduced phase
separation, photoinduced self-poling effect, and electrical-field driven reversible conversion between lead iodide (PbI2) and
methylammonium lead triiodide (MAPbI3). Undoubtedly thorough insight into the ion-migration mechanism is highly desired
for the development of OTP based devices to improve intrinsic stability in the dark and under illumination. In this Account, we
critically review the recent progress in understanding the fundamental science on ion migration in OTP based solar cells. We
look into both theoretical and experiment advances in answering these basic questions: Does ion migration occur and cause the
photocurrent hysteresis in perovskite solar cells? What are the migrating ion species? How do ions migrate? How does ion
migration impact the device efficiency and stability? How can ion migration be mitigated or eliminated? We also raise some
questions that need to be understood and addressed in the future.

description: FeLoBALs are a rare class of quasar outflows with low-ionization broad absorption lines (BALs), large column densities, and potentially large kinetic energies that might be important for `feedback' to galaxy evolution. In order to probe the physical properties of these outflows, we conducted a multiple-epoch, absorption line variability study of 12 FeLoBAL quasars spanning a redshift range between 0.7 and 1.9 over rest frame time-scales of approximately 10 d to 7.6 yr. We detect absorption line variability with greater than 8 sigma confidence in 3 out of the 12 sources in our sample over time-scales of 0.6 to 7.6 yr. Variable wavelength intervals are associated with ground and excited state Fe II multiplets, the Mg II 2796, 2803 doublet, Mg I 2852, and excited state Ni II multiplets. The observed variability along with evidence of saturation in the absorption lines favors transverse motions of gas across the line of sight (LOS) as the preferred scenario, and allows us to constrain the outflow distance from the supermassive black hole (SMBH) to be less than 69, 7, and 60 pc for our three variable sources. In combination with other studies, these results suggest that the outflowing gas in FeLoBAL quasars resides on a range of scales and includes matter within tens of parsecs of the central source.

description: The light-trajectory in the gravitational field of N extended bodies in arbitrary motion is determined in the first post-Newtonian approximation. According to the theory of reference systems, the gravitational fields of these massive bodies are expressed in terms of their intrinsic multipoles, allowing for arbitrary shape and inner structure of these bodies. The results of this investigation aim towards a consistent general-relativistic theory of light propagation in the Solar system for high-precision astrometry at sub-micro-arcsecond level of accuracy.

description: We investigate decoupling, one of the most important primitives in quantum Shannon theory, by replacing the uniformly distributed random unitaries commonly used to achieve the protocol, with repeated applications of random unitaries diagonal in the Pauli-$Z$ and -$X$ bases. This strategy was recently shown to achieve an approximate unitary $2$-design after a number of repetitions of the process, which implies that the strategy gradually achieves decoupling. Here, we prove that even fewer repetitions of the process achieve decoupling at the same rate as that with the uniform ones, showing that rather imprecise approximations of unitary $2$-designs are sufficient for decoupling. We also briefly discuss efficient implementations of them and implications of our decoupling theorem to coherent state merging and relative thermalisation.

title: The soft channels of policy diffusion: Insights from local climate change adaptation policy
Creators: name: Schulze, Kai
Publisher: name: Wiley
Year: 2024

description: Diffusion has become both an important concept for studying policy spread and a popular governance approach, particularly where direct coercion is unavailable or undesirable.
However, the prevailing mechanism-centered concept is difficult to measure and poorly captures the governance potential of policy diffusion. To address these issues, this article presents a new channel-centered framework that distinguishes between six soft policy diffusion channels: autonomous, collaborative, exemplary, persuasive, organized, and funded diffusion. The framework is probed by studying local climate change adaptation policy using original survey data collected from the administrations of 190 municipalities located in the central German state of Hessen. The regression results indicate that the local
institutionalization of adaptation in Hessen is associated with several interventions by higher levels of government, including the provision of a policy model, a municipal climate network, and grant programs. However, the density of concrete adaptation measures is associated with noninstitutionalized exchanges between municipalities. External grants are also found to be more effective in institutionalizing adaptation in larger municipalities. These results demonstrate the usefulness of the framework for distinguishing and comparing different diffusion channels and suggest that different types of interventions may be required to effectively support adaptation policy development at the local level.

description: Organic semiconductors with higher carrier mobility and better transparency have been
actively pursued for numerous applications, such as flat-panel display backplane and sensor
arrays. The carrier mobility is an important figure of merit and is sensitively influenced by the
crystallinity and the molecular arrangement in a crystal lattice. Here we describe the growth
of a highly aligned meta-stable structure of 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene
(C8-BTBT) from a blended solution of C8-BTBT and polystyrene by using a novel offcentre
spin-coating method. Combined with a vertical phase separation of the blend, the
highly aligned, meta-stable C8-BTBT films provide a significantly increased thin film transistor
hole mobility up to 43 cm2 Vs1 (25 cm2 Vs1 on average), which is the highest value
reported to date for all organic molecules. The resulting transistors show high transparency of
490% over the visible spectrum, indicating their potential for transparent, high-performance
organic electronics.

description: The risk of harm to patients is always present within healthcare systems. The World Health Organisation estimates that in high income countries, as many as one in ten patients are harmed while receiving hospital care. Ideally the probable treatment benefits patients receive from their care outweigh these risks, but this is not the case for patients receiving low-value care (health care that likely provides little benefit to patients relative to its cost). Our aim in this project is to investigate the resulting harms and costs to Medicare and its beneficiaries from potential low-value services. Many studies have quantified the prevalence of low-value interventions using administrative data. Fewer have quantified the downstream consequences of interventions. Those that have include the additional health care services (the ‘care cascades’) after low-value testing or imaging. An Australian study reported hospital-acquired complications reported in New South Wales hospital episodes where the primary procedure was one of seven low-value procedures. These authors (also led by our study lead) found that between 0.2% and 15% of patients with a low-value procedure had a hospital-acquired complication, and that these complications led to a doubling of the median length of stay compared to those without a complication. While the prevalence and direct costs of low-value interventions have previously been measured in US Medicare claims data, our study will investigate the additional costs and harms resulting from these low-value interventions within this population.

description: Project monitoring and evaluation process is critical for the success of a project, since it is the most integrated process of all. Besides its own intended activities, the process measures the performance of other process groups. However, the results in previous studies at various projects show low rating practices of monitoring and evaluation. The challenges of project monitoring and evaluation process observed in most projects may generate from internal or external factors. The internal factors could be: perception (implementer’s altitude & commitment), M&E planning quality, selection of M&E tools, M&E expert level and budgeting; whereas, the external challenges may arise from: organization policy, stakeholder communication or politics

title: Becoming a second language teacher: developing graduate attributes in an international landscape of academic and professional practices

Subjects: subject: Graduate attributes, higher education, internationalisation, international students, language teacher education, language teaching.

description: Higher Education Institutes in the twenty-first century find themselves subject to global economic forces which have reoriented the purpose of a tertiary education towards employment, with an objective of producing graduates to meet the demands of the workplace. Central to this, graduate attribute frameworks set out each institution’s version of the skill set which the employable graduate should possess. However, these idealised visions may often fail to adequately account for the diversity of the student body and their applicability to their future employment contexts is questionable. Where international students are enrolled on vocationally oriented postgraduate programmes, it is unclear what such frameworks may mean for them. Drawing on phenomenographic interviews with twenty international students from a Second Language Teacher Education programme at a Scottish university, this study shows that there is limited alignment between the student and institutional conceptualisation of graduate attributes. Moreover, it is demonstrated that the students’ development of any such attributes is both constrained and enabled by the navigation and membership of a complex landscape of both academic and professional communities of practice.

description: The large photocurrent hysteresis observed in many organometal trihalide perovskite solar
cells has become a major hindrance impairing the ultimate performance and stability of these
devices, while its origin was unknown. Here we demonstrate the trap states on the surface
and grain boundaries of the perovskite materials to be the origin of photocurrent hysteresis
and that the fullerene layers deposited on perovskites can effectively passivate these charge
trap states and eliminate the notorious photocurrent hysteresis. Fullerenes deposited on
the top of the perovskites reduce the trap density by two orders of magnitude and double
the power conversion efficiency of CH3NH3PbI3 solar cells. The elucidation of the origin
of photocurrent hysteresis and its elimination by trap passivation in perovskite solar cells
provides important directions for future enhancements to device efficiency.
Progress Towards a Diffuse Neutrino Search in the Full Livetime of the Askaryan Radio Array

description: The Askaryan Radio Array (ARA) is an in-ice ultrahigh energy (UHE, $>10$ PeV) neutrino experiment at the South Pole that aims to detect radio emissions from neutrino-induced particle cascades. ARA has five independent stations which together have collected nearly 24 station-years of data. Each of these stations search for UHE neutrinos by burying in-ice clusters of antennas $\sim 200$ m deep in a roughly cubical lattice with side length $\sim 15$ m. Additionally, the fifth ARA station (A5) has a beamforming trigger, referred to as the Phased Array (PA), consisting of a trigger array of 7 tightly packed vertically-polarized antennas. In this proceeding, we will present a neutrino search with the data of this "hybrid" station, emphasizing its capabilities for improved analysis efficiencies, background rejection, and neutrino vertex reconstruction. This is enabled by combining the closely packed trigger antennas with the long-baselines of the outrigger antennas. We will also place the A5 analysis into the context of the broader five station analysis program, including efforts to characterize and calibrate the detector, model and constrain backgrounds, and reject noise across the entire array. We anticipate this full neutrino search to set world-leading limits above 100 PeV, and inform the next generation of neutrino detection experiments.

description: Large-aspect-ratio grains are needed in polycrystalline thin-film solar cells for reduced charge
recombination at grain boundaries; however, the grain size in organolead trihalide perovskite
(OTP) films is generally limited by the film thickness. Here we report the growth of OTP
grains with high average aspect ratio of 2.3–7.9 on a wide range of non-wetting hole transport
layers (HTLs), which increase nucleus spacing by suppressing heterogeneous nucleation and
facilitate grain boundary migration in grain growth by imposing less drag force. The reduced
grain boundary area and improved crystallinity dramatically reduce the charge recombination
in OTP thin films to the level in OTP single crystals. Combining the high work function of
several HTLs, a high stabilized device efficiency of 18.3% in low-temperature-processed
planar-heterojunction OTP devices under 1 sun illumination is achieved. This simple method
in enhancing OTP morphology paves the way for its application in other optoelectronic
devices for enhanced performance.

description: We propose a method for construction of Darboux transformations, which is a new development of the dressing method for Lax operators invariant under a reduction group. We apply the method to the vector sine-Gordon equation and derive its Bäcklund transformations. We show that there is a new Lax operator canonically associated with our Darboux transformation resulting an evolutionary differential-difference system on a sphere. The latter is a generalised symmetry for the chain of Bäcklund transformations. Using the re-factorisation approach and the Bianchi permutability of the Darboux transformations we derive new vector Yang-Baxter map and integrable discrete vector sine-Gordon equation on a sphere.

description: In this paper, we analyze the geodesics of the 4-dimensional ($4D$) linear dilaton black hole (LDBH) spacetime, which is an exact solution to the Einstein-Maxwell-Dilaton (EMD) theory. LDBHs have non-asymptotically flat (NAF) geometry, and their Hawking radiation is an isothermal process. The geodesics motions of the test particles are studied via the standard Lagrangian method. After obtaining the Euler-Lagrange (EL) equations, we show that exact analytical solutions to the radial and angular geodesic equations can be obtained. In particular, it is shown that one of the possible solutions for the radial trajectories can be given in terms of the WeierstrassP-function ($\wp$-function), which is an elliptic-type special function.

description: Uno dei possibili approcci per integrare processi di apprendimento formale, non-formale e informale nei contesi dello sviluppo professionale continuo è quello di ricreare, all’interno di un evento formativo formale, le tipiche dinamiche che innescano i processi di apprendimento informale/incidentale, nello specifico, quelle centrate su attività di problem solving collaborativo. Uno di tali approcci è stato l’oggetto dell’esperienza descritta in questo articolo, che ha avuto come tema centrale l’uso delle mappe concettuali come strumento teso a favorire e potenziare i flussi informali di conoscenza all’interno di gruppi di professionisti partecipanti a un evento formativo formale. Sulla base dei riscontri forniti dai partecipanti, è emerso che le mappe concettuali possono essere un utile strumento: i) di autovalutazione del proprio apprendimento in un contesto formale; ii) di supporto all’apprendimento collaborativo informale.

description: We selected the claim that each subject that has risk-preference parameters less than intertemporal-substitution-preference parameters (alpha < phi) should prefer early resolution of uncertainty; they should choose to roll immediately in the uncertainty-resolution-preference elicitation task. This reflects the following statement from the paper’s abstract: “Regression results show that types predicted by the Epstein–Zin model to prefer early resolution choose early resolution with 20%–50% higher probability.” The claim was tested by using regression analysis to properly test the model, and controlling for the error-in-variables problem (the fact that the regressors are estimated quantities) using the Erickson-Whited higher-order-moments method, which resulted in subjects completely classified as early-preferring types choosing the early option with 50% more probability (two-tailed p value < 0.01) than those classified as indifferent types. From Table 5 - coefficient of subject choice on the posterior probability of being in an early-preferring group = 0.507, significant at the 1% level. The focal test in the original paper is: Coefficient of subject choice on the posterior probability of being in an early-preferring group = 0.507, significant at the 1% level.

It has already been shown that there is a correlation between the development of the bones of the hand and wrist (gold standard method) and other body structures. Several studies have also suggested that there is a correlation between the maturation of the cervical vertebrae and the teeth. Given that the information on this relationship is controversial, we consider it necessary to systematically review all the existing literature and the state of evidence on this topic.

description: In this paper, we explore a novel observational signature of gravitational corrections during slow-roll inflation. We study the coupling of the inflaton field to higher-curvature tensors in models with a minimal breaking of conformal symmetry. In that case, the most general correction to the tensor two-point function is captured by a coupling to the square of the Weyl tensor. We show that these scenarios lead to a correction to the tilt of the tensor power spectrum and hence a violation of the tensor consistency condition. We arrive at the same conclusion through an analysis in conformal perturbation theory.

description: The more a prospect’s frame is associated with risk and the lower a prospect’s low (but not high) possible outcome, the lower people’s WTP [willingness to pay]; the effect of frame on WTP is the portion of this hypothesis selected for the SCORE program. This reflects the following statement from the paper's abstract: "Buyers’ willingness to pay is influenced by the extent to which a risky prospect’s frame is associated with risk (Experiment 1)..." The claim is tested with an experiment where participants were asked to indicate their WTP for a risky prospect that was framed as either a lottery ticket or an uncertain gift card. In the lottery condition, the lottery ticket would for sure yield either a $10 or a $20 Best Buy gift card (both equally likely). In the gift card condition, the gift card would be either a $10 or a $20 Best Buy gift card (both equally likely). Participants were told that the authors would randomly select five respondents to get a $20 bonus and an opportunity to purchase a lottery ticket or a gift card. If their WTP was above the reservation price (the reservation price was not revealed to participants), they would buy the lottery ticket or gift card at the authors’ reservation price. If their WTP was below the reservation price, they would not buy the lottery ticket or gift card. In the test of the claim selected for the SCORE program, the authors analyze WTP with a t-test. Participants in the lottery condition were willing to pay less (M = $5.68, SD = $6.69, Mdn = $5.00) than participants in the gift card condition (M = $9.52, SD = $4.48, Mdn = $7.50; t(99) = 3.43, p < .001, partial eta-squared = .11).

description: Anaphylaxis is a sudden-onset, severe, generalized or systemic hypersensitivity reaction that can affect people of any age. Children and younger age groups are at a disproportionately increased risk of hospitalization and emergency department admission due to anaphylaxis. Parents and caregivers of young children have a crucial role in prevention, early detection, and successful management of sudden-onset and severe reactions, by exerting constant vigilance to identify and avoid the allergens, and by identifying early signs and symptoms. To enhance parents’ coping mechanism with stressful acute events related to their child’s anaphylaxis and to establish family-centered management strategies, a comprehensive understanding of parents’ experiences and information needs is essential. Thus, we are undertaking a systematic review of the primary research in this area, to investigate parents’ experiences and information needs in relation to their child’s anaphylaxis, in order to identify gaps in parental health literacy and address areas of improvement. This will be an important step in establishing strategic decision-making, improving quality of care, and meeting patients’ expectations, leading to effective provision of healthcare resources.

description: Organometal trihalide perovskites have been demonstrated as excellent light absorbers for high-efficiency photovoltaic
applications. Previous approaches to increasing the solar cell eciency have focused on optimization of the grain morphology
of perovskite thin films. Here, we show that the structural order of the electron transport layers also has a significant
impact on solar cell performance.We demonstrate that the power conversion efficiency of CH3NH3PbI3 planar heterojunction
photovoltaic cells increases from 17.1 to 19.4% when the energy disorder in the fullerene electron transport layer is reduced
by a simple solvent annealing process. The increase in eciency is the result of the enhancement in open-circuit voltage from
1.04 to 1.13V without sacrificing the short-circuit current and fill factor. These results shed light on the origin of open-circuit
voltage in perovskite solar cells, and provide a path to further increase their efficiency.

description: Infrared spectroscopy is the technique of choice for chemical identification of biomolecules through their vibrational fingerprints. However, infrared light interacts poorly with nanometric size molecules. Here, we exploit the unique electro-optical properties of graphene to demonstrate a high-sensitivity tunable plasmonic biosensor for chemically-specific label-free detection of protein monolayers. The plasmon resonance of nanostructured graphene is dynamically tuned to selectively probe the protein at different frequencies and extract its complex refractive index. Additionally, the extreme spatial light confinement in graphene, up to two orders of magnitude higher than in metals, produces an unprecedentedly high overlap with nanometric biomolecules, enabling superior sensitivity in the detection of their refractive index and vibrational fingerprints. The combination of tunable spectral selectivity and enhanced sensitivity of graphene opens exciting prospects for biosensing.

description: Several meta-analyses have summarized evidence on the associations between PPI use and adverse health outcomes in several populations. However, the credibility of the evidence from these meta-analyses is uncertain. An umbrella review that allows a systematic collection and assessment of information from multiple systematic reviews and meta-analyses on this topic will be performed (Ioannidis, 2009).

description: We prove sharp weak and strong type weighted estimates for a class of dyadic operators that includes majorants of both standard singular integrals and square functions. Our main new result is the optimal bound $[w]_{A_p}^{1/p}[w]_{A_\infty}^{1/2-1/p}\lesssim [w]_{A_p}^{1/2}$ for the weak type norm of square functions on $L^p(w)$ for $p>2$; previously, such a bound was only known with a logarithmic correction. By the same approach, we also recover several related results in a streamlined manner.

description: Individual differences in agentic extraversion are thought to partly arise from individual differences in dopaminergic functioning (Depue & Collins, 1999; Depue et al., 1994; Wacker & Smillie, 2015). Our goal is to investigate the relationship between extraversion and dopaminergic activity on a state level by experimentally manipulating extraverted behavior. We will use the spontaneous eyeblink rate as a measure for dopaminergic activity, as it has been demonstrated to be a reliable indicator (Chermahini & Hommel, 2012; Depue et al., 1994; Jongkees & Colzato, 2016; Karson, 1983). We therefore investigate the effects of enacted extraversion vs. enacted introversion (vs. no acting instruction) on spontaneous eyeblink rate.
Optimization and Characterization of Silica Synthesized from Rice husk

description: Rice husks are agricultural biomass waste, which is considered as renewable resources that are produced every year in Ethiopia. Despite of its non-commercial value and causing environmental pollutions, its ash content is rich in silica (SiO2) and becomes an economic potential source. This study aims at utilizing this agricultural biomass waste into valuable product, silica. Silica (SiO2) was prepared by using rice husk ash (RHA) as a source of silicate (SiO-2 3) . Then further reaction of the ash with NaOH has formed Sodium silicate (Na2SiO3) solution. Then, titration of this solution with HCl forms the precipitation of silicagel. The effect of acid pretreatment on the removal of metallic impurities and its percentage purity as well as on the properties of RHA was examined using Atomic Absorption Spectrophotometer (AAS). The percentage purity of SiO2 in the untreated RH were found 87.1% with some metallic impurities and 97.6% purity of silica is obtained from the treated RH, which proved to be effective in removing the metallic impurities to a very lower level and enhance the purity of silica in the RHA. The experiment and statistical analysis for the production of SiO2 were designed using three-level-three-factor BBD for the total run of 17 experiments at operating process conditions of acid concentration (1-2N), pyrolysis temperature (450-850C) and Pyrolysis time (1-5h). The optimal %yield were found to be 98.971% with 98.6% purity of SiO2% at conditions for 1.95N pretreatment acid concentration,658C pyrolysis temperature, and 4.95h pyrolysis time.
title: Physiology-guided optimisation of percutaneous coronary intervention

Publisher: name: University of Glasgow

description: Aims A fractional flow reserve (FFR) value ≥ 0.90 after percutaneous coronary intervention (PCI) is associated with a reduced risk of adverse cardiovascular events. TARGET-FFR was an investigator-initiated, single centre, randomised controlled trial to determine the feasibility and efficacy of a post-PCI FFRguided optimisation strategy versus standard coronary angiography in achieving final post-PCI FFR values ≥ 0.90. Methods and Results After angiographically-guided PCI, patients were randomised 1:1 to receive a Physiology-guided Incremental Optimisation Strategy (PIOS) or a blinded coronary physiology assessment (control group). The primary outcome was the proportion of patients with a final post-PCI FFR ≥ 0.90. Final FFR ≤ 0.80 was a prioritised secondary outcome. 260 patients were randomised (131 to PIOS, 129 to control). 68.1% of patients had an initial post-PCI FFR < 0.90. In the PIOS group, 30.5% underwent further intervention (stent post-dilation and/or additional stenting). There was no significant difference in the primary endpoint of the proportion of patients with final post-PCI FFR ≥ 0.90 between groups (PIOS minus control 10%, 95% CI -1.84 to 21.91, p=0.099). The proportion of patients with a final FFR ≤ 0.80 was significantly reduced when compared to the angiography-guided control group (-11.2%, 95% CI -21.87 to -0.35, p=0.045). Conclusion Over two-thirds of patients had a physiologically suboptimal result after angiographically guided PCI. A post-PCI FFR-guided optimisation strategy did not significantly increase the proportion of patients with a final FFR ≥ 0.90 but did reduce the proportion of patients with a final FFR ≤ 0.80. Larger increases in FFR following PCI were associated with greater improvements in patient-reported angina and quality-of-life.

description: We utilize the recently demonstrated orders of magnitude enhancement of extremely nondegenerate two-photon absorption in direct-gap semiconductor photodiodes to perform scanned imaging of 3D structures using IR femtosecond illumination pulses (1.6 um and 4.93 um) gated on the GaN detector by sub-gap, femtosecond pulses. While transverse resolution is limited by the usual imaging criteria, the longitudinal or depth resolution can be less than a wavelength, dependent on the pulsewidths in this nonlinear interaction within the detector element. The imaging system can accommodate a wide range of wavelengths in the mid-IR and near-IR without the need to modify the detection and imaging systems.

description: Isoprene is a significant source of atmospheric organic aerosol;
however, the oxidation pathways that lead to secondary organic
aerosol (SOA) have remained elusive. Here, we identify the role
of two key reactive intermediates, epoxydiols of isoprene (IEPOX ¼
β-IEPOX þ δ-IEPOX) and methacryloylperoxynitrate (MPAN), which
are formed during isoprene oxidation under low- and high-NOx
conditions, respectively. Isoprene low-NOx SOA is enhanced in
the presence of acidified sulfate seed aerosol (mass yield 28.6%)
over that in the presence of neutral aerosol (mass yield 1.3%). Increased
uptake of IEPOX by acid-catalyzed particle-phase reactions
is shown to explain this enhancement. Under high-NOx conditions,
isoprene SOA formation occurs through oxidation of its secondgeneration
product, MPAN. The similarity of the composition of
SOA formed from the photooxidation of MPAN to that formed
from isoprene and methacrolein demonstrates the role of MPAN
in the formation of isoprene high-NOx SOA. Reactions of IEPOX
and MPAN in the presence of anthropogenic pollutants (i.e., acidic
aerosol produced from the oxidation of SO2 and NO2, respectively)
could be a substantial source of “missing urban SOA” not included
in current atmospheric models.
Relations on $\overline M_{g,n}$ via equivariant Gromov-Witten theory of $\mathbb P^1$

description: We give a proof of Pixton's generalized Faber-Zagier relations in the tautological Chow ring of $\overline M_{g,n}$. The strategy is very similar to the work of Pandharipande-Pixton-Zvonkine, who have given a proof of the same result in cohomology. The main tool is the Givental-Teleman classification of semisimple cohomological field theories, which, while in general only known in cohomology, via virtual localization can be shown to be also valid in Chow for the equivariant Gromov-Witten theory of the projective line. We obtain the relations just from this theory.
