Rapid warming in the Arctic has a huge impact on global environment. Atmospheric brown carbon (BrC) is one of least understood and uncertain agents due to scarcity observations. Here, we performed direct observations atmospheric BrC quantified its light-absorbing properties during 2-month circum-Arctic cruise summer 2017. Through observation-constrained modeling, show that BrC, mainly originated from biomass burning mid- high latitudes Northern Hemisphere (∼60%), can be strong agent region,...
Abstract Conductive hydrogels have shown significant potential in the realm of flexible electronics; however, using water as a solvent introduces problems such low‐temperature freezing and loss. One possible solution to address these limitations is replacing with deep eutectic solvents (DES). In this study, PHEAA–gelatin–MXene (PGM) eutectogels are constructed poly( N ‐hydroxyethyl acrylamide) (PHEAA) gelatin main components, MXene nanosheets added nanofillers. The PGM exhibit exceptional...
Snow serves as a vital scavenging mechanism to gas-phase and particle-phase organic nitrogen substances in the atmosphere, providing significant link between land-atmosphere flux of surface-earth system. Here, we used optical instruments (UV–vis excitation-emission matrix fluorescence) Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS) elucidate molecular composition potential precursors snow samples collected simultaneously at four megacities North China. The elemental...
Although hydrogel-based patches have shown promising therapeutic efficacy in myocardial infarction (MI), synergistic mechanical, electrical, and biological cues are required to restore cardiac electrical conduction diastolic–systolic function. Here, an injectable mechanical–electrical coupling hydrogel patch (MEHP) is developed via dynamic covalent/noncovalent cross-linking, appropriate for cell encapsulation minimally invasive implantation into the pericardial cavity. Pericardial fixation...
Abstract. Firework (FW) emission has strong impacts on air quality and public health. However, little is known about the molecular composition of FW-related airborne particulate matter (PM), especially organic fraction. Here we describe detailed Beijing PM collected before, during, after a FW event in evening New Year's Eve 2012. Subgroups CHO, CHON, CHOS were characterized using ultrahigh-resolution Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry. These subgroups...
This communication describes the design of bifunctional VOx/TS-1 catalysts with enhanced redox and acidic character via doping SO42− PO43− for selective oxidation methanol to dimethoxymethane. Redox sites enable production formaldehyde, while favor condensation formaldehyde DMM.
Dissolved organic matter (DOM) is an ultracomplex mixture of compounds in the land/ocean–atmosphere interface. Normally, polar from DOM are hardly retained by liquid chromatography (LC) columns for further analytical purposes. Here, we utilized Fourier transform ion cyclotron resonance mass spectrometry with LC online analysis river water and rainwater. With sophisticated instrumental optimization, different portions metal salts, carboxyl-rich alicyclic molecules, organosulfates (OSs),...
The chemical composition of dissolved organic sulfur in snow is important understanding the sources and scavenging processes atmospheric matter. Snow samples collected simultaneously from four megacities North China were analyzed using ultra-high-resolution Fourier transform ion cyclotron resonance mass spectrometry. modified oxygen redefined aromaticity index help interpretation possible structural information evaluation sulfur-containing molecules. By extending these parameters, we provide...
Abstract. Biomass burning is one of the key sources urban aerosols in North China Plain, especially during winter, when impact secondary organic (SOAs) formed from biogenic volatile compounds (BVOCs) generally considered to be minor. However, little known about influence SOA loading on molecular composition wintertime aerosols. Here, we investigated water-soluble fine particulate matter (PM2.5) Tianjin by ultrahigh-resolution Fourier transform ion cyclotron resonanc mass spectrometry (FT-ICR...
Due to the limited memory and computing resources in real application of target detection, method is challenging implement on mobile embedded devices. In order achieve balance between detection accuracy speed pedestrian-intensive scenes, an improved lightweight dense pedestrian algorithm GS-YOLOv5 (GhostNet GSConv- SIoU) proposed this paper. Backbone section, GhostNet used replace original CSPDarknet53 network structure, reducing number parameters computation. The CBL module replaced with...
Globally, cancer is a serious health problem. It unfortunate that current anti-cancer strategies are insufficiently specific and damage the normal tissues. There's urgent need for development of new strategies. More recently, increasing attention has been paid to application ferroptosis nano materials in research. Ferroptosis, condition characterized by excessive reactive oxygen species-induced lipid peroxidation, as programmed cell death mode, exists process number diseases, including...
