Developing new materials and technologies for efficient CO2 capture, particularly separation of post-combustion, will significantly reduce the concentration its impacts on environment. A challenge capture is to obtain high performance adsorbents with both selectivity easy regeneration. Here, capture/regeneration MoS2 monolayers controlled by turning on/off external electric fields comprehensively investigated through a density functional theory calculation. The calculated results indicate...
Detection of the concentration amyloid monomers is great importance in diagnosis amyloidogenesis. Herein, we propose a method to detect β (Aβ) peptide by utilizing fluorescence characteristics graphene quantum dots (GQDs). The linear dependence photoluminescence (PL) intensity GQDs on Aβ monomer can be identified. It further illustrated that both monomeric and fibrillar peptides monitored using GQDs. Conventional fluorescent dyes, such as thioflavin T (ThT), usually undergo co-incubation...
Abstract. This study is concerned with the impacts of organic aerosols on cloud condensation nuclei (CCN) activity based field measurements made at a suburban site in Northern China. The sensitivity estimated CCN number concentration (NCCN) to both volume fraction material (xorg) and aerosol oxidation level (using f44, m∕z 44 material) are examined. A strong dependence xorg f44 was noted. NCCN organics increased increasing xorg. particles oxidization or aging estimating were also very...
Abstract Using the 1985–2013 record of near-surface currents from satellite-tracked drifters, pseudo-Eulerian statistics circulation in Indian Ocean (IO) are analyzed. It is found that distributions current velocities and mean kinetic energy (MKE) IO extremely inhomogeneous space nonstationary time. The most energetic regions with climatologic velocity over 50 cm s −1 MKE 500 2 −2 off eastern coast Somalia (with maxima 100 1500 ) equatorial IO, associated strong, annually reversing Current...
The microtubule-associated protein tau is involved in Alzheimer's disease and other tauopathies. Recently, has been shown to undergo liquid-liquid phase separation (LLPS), which implicated the physiological function pathological aggregation of tau. In this report, we demonstrate that green tea polyphenol (-)-epigallocatechin-3-gallate (EGCG) promotes formation liquid droplets at neutral pH by creating a network hydrophobic interactions hydrogen bonds, mainly with proline-rich domain We...
Using remote sensing imagery of the Yellow River Delta (YRD) from 1984 to 2024, Digital Shoreline Analysis System (DSAS) model was employed analyze coastline position, migration rate, and characteristics four typical coastal sections. The response changes in study area global climate change human activities quantitatively assessed. Over past 40 years, modern YRD has generally advanced seaward at an average rate 109.64 m/a. This progression can be divided into three distinct phases: (i) rapid...
Density functional theory (DFT) calculations have been performed to unravel the mechanism of Lewis-acid-induced Ni(cod)2-catalyzed selective coupling reactions one diketene and two alkynes. Complex mixtures (unsymmetrical phenylacetic acid P1, symmetrical P2 (3E)-4-ethyl-5-methylene-3-heptenoic P3) were obtained in absence Et2Al(OEt). P1 formation involves C(sp2)-O oxidative addition diketene, twice alkyne insertion, intramolecular C═C acidolysis, β-H elimination. For P2/P3 formation, common...
Criegee intermediates (CIs) play a key role in controlling the atmospheric budget of hydroxyl radical, organic acids, and secondary aerosols. In this study, detailed reaction mechanisms simplest intermediate CH2OO its derivatives with methane (CH4) have been systematically investigated theoretically. Two pathways A B identified for title reaction. pathway A, CIs can act as an oxygen donor by inserting terminal atom into C-H bond alkanes, resulting formation alcohol species. The corresponding...
Abstract. The Tibetan Plateau is a global hotspot of stratospheric intrusion, and elevated surface ozone was observed at ground monitoring sites. Still, links between the variability intrusion regional scale remain unclear. This study synthesized measurements over analyzed their seasonal variations. monthly mean concentrations peaked earlier in south April May later north June July. migration peaks coupled with synchronous movement tropopause folds westerly jet that created conditions...
The discovery of advanced materials with high selectivity and efficiency is essential to realize practical carbon capture sequestration. Here, we have investigated the interactions Co@B8/Co@B8– M@B9/M@B9– (M = Ir, Rh, Ru) clusters CO2, N2, CH4 gas molecules theoretically. We found that neutral boron weak interaction molecules. Similarly, their negative charge states also N2 However, anionic a strong which can be explained by Lewis acid–base as CO2 (Lewis acid) gain electron easily from...
Abstract Lagrangian statistics of the surface circulation in Indian Ocean (IO) are investigated using drifter observations during 1985–2013. The methodology isolates influence low-frequency variations and horizontal shear mean flow. estimated spatially inhomogeneous anisotropic over IO basin, with values ~6–85 × 10 7 cm 2 s −1 for diffusivity, ~2–7 days integral time scale, ~33–223 km length scale. Large diffusivities (>20 ) occur central-eastern equatorial eastern African coast. Small...

Abstract Background Donor human milk is the best alternative for preterm infants when their mother’s own insufficient or unavailable. The development of banks in China started late, and most these banks, amount donor clinical demand. Moreover, many mothers are reluctant to use due safety concerns. It important understand potential supply demand before establishing a new bank. This study aimed women’s acceptance banking Wenzhou, southeastern China. Methods A cross-sectional was conducted...
Accurate vertical (adiabatic) ionization potential (IP) and valence electron affinity (EA) of glycinamide, including its possible conformers, have been determined employing density functional theory (B3LYP) with 6-311++G** 6-311G** basis sets, respectively.
