Abstract. In 2013, China's government published the Air Pollution Prevention and Control Action Plan (APPCAP) with a specific target for Beijing, which aims to reduce annual mean PM2.5 concentrations in Beijing 60 µg m−3 2017. During 2013–2017, air quality was significantly improved following implementation of various emission control measures locally regionally, concentration decreasing from 89.5 2013 58 As meteorological conditions were more favourable reduction pollution 2017 than 2016,...
Abstract Gestational exposure to ambient fine particles (PM 2.5 ) increases the risk of stillbirth, but related disease burden is unknown, particularly in low- and middle-income countries (LMICs). We combine state-of-the-art estimates on stillbirths, multiple exposure–response functions obtained from previous meta-analyses or derived by a self-matched case-control study 54 LMICs. 13,870 stillbirths 32,449 livebirths are extracted 113 geocoded surveys Demographic Health Surveys.

Abstract. We describe a new generation of the high-performance GEOS-Chem (GCHP) global model atmospheric composition developed as part version 13 series. is an open-source grid-independent that can be used online within meteorological simulation or offline using archived data. GCHP implementation driven by NASA Goddard Earth Observing System (GEOS) data for massively parallel simulations. Version offers major advances in ease use, computational performance, versatility, resolution, and...
Abstract. Accurate representation of mineral dust remains a challenge for global air quality or climate models due to inadequate parametrization the emission scheme, removal mechanisms, and size distribution. While various studies have constrained aspects fluxes and/or optical depth, surface concentrations still vary by factors 5–10 among models. In this study, we focus on improving simulation fine in GEOS-Chem chemical transport model, leveraging recent mechanistic understanding source...
A nickel and chiral spiroBox ligand catalytic system provides a facile synthesis of optically active 2-indolyl-1-nitro derivatives with high yield enantioselectivity.
Novel “task-specific” DESs were developed for Beckmann rearrangement to prepare ε-caprolactam, with [InCl 3 ][AA] 2 enabling 100% CHO conversion and 99.5% CPL selectivity under 80 °C h.
Abstract Emissions in many sources are estimated municipal district totals and spatially disaggregated onto grid cells using empirically selected spatial proxies such as population density, which might introduce biases, especially fine scale. Efforts have been made to improve the representation of emission inventory, by incorporating comprehensive point source database (e.g. power plants, industrial facilities) estimates. Satellite-based observations from TROPOspheric Monitoring Instrument...
Abstract. The capability of chemical transport models to represent fine particulate matter (PM2.5) over the course a day is vital importance for air quality simulation and assessment. In this work, we used nested GEOS-Chem model at 0.25∘×0.3125∘ resolution simulate diel (24 h) variation in PM2.5 mass concentrations contiguous United States (US) 2016. We evaluate simulations with situ measurements from national monitoring network. Our base case broadly reproduces observed morning peak,...
Abstract. Ambient fine particulate matter (PM2.5) is the leading global environmental determinant of mortality. However, large gaps exist in ground-based PM2.5 monitoring. Satellite remote sensing aerosol optical depth (AOD) offers information to help fill these worldwide when augmented with a modeled PM2.5–AOD relationship. This study aims understand spatial pattern and driving factors this relationship by examining η (PM2.5AOD) using both observations modeling. A observational estimate for...
Sustainable Development Goals (SDGs) target 11.a is a good vision for the coordinated development of economy, society and environment in urban agglomerations. However, there was an extreme lack indicators, data or case studies SDG 11.a, since it vague “process target”, which not conducive to implementation 11.a. It important propose quantitative, convenient, local policies relevant method promote realization test effects Combined with socio-economic land use data, this study uses methods...

Abstract Based on a biodegradable cross-linker, N-maleyl chitosan (N-MACH), series of Poly(N-isopropylacrylamide) (PNIPAAm) and Poly(N-isopropylacrylamide-co-acrylamide) [P(NIPAAm-co-Am)] hydrogels were prepared, their lower critical solution temperature (LCST), swelling kinetics, equilibrium ratio in NaCl solution, enzymatic degradation behavior simulated gastric fluids (SGF) discussed. The LCST did not change with different cross-linker contents. By altering the NIPAAm/Am molar...
