Analyses involving data from many locations throughout the world have now been conducted to assess association between air pollution and mortality. To date, six independent analyses of mortality for Philadelphia, Pennsylvania, reported. In this new analysis Philadelphia 1974–1988, Poisson regression models were developed estimate increased risk daily associated with while controlling longer-term time trends season weather. Model development was based on prior understanding effects these...
Chemical conversion of CO2 is providing an opportunity to mitigate the global warming induced by overconsumption fossil fuel. Cu has been regarded as one most powerful contenders in catalyzing conversion, yet precise manipulation its surface state and nearby chemical environment continues pose a formidable challenge. In this work, we report high-efficiency catalyst utilizing CeO2 pure silicon zeolite (S1) co-activate species. CO2-to-methanol (CTM) space-time yield methanol (STYMeOH) obtained...
The chemical curiosity "planar tetracoordinate carbon" (ptC) has greatly broadened one's knowledge of molecular bonding motifs apart from the traditional, tetrahedral, van't Hoff and LeBel's concept. Synthesized ptC examples have been reported either in solid state or gas phase, where core is usually metalized organometallized. Surprisingly, there no experimental report on hydrogenated to date. A possible answer this situation could be "promiscuity" hydrogen when binding other elements,...
Supramolecular chemistry offers an exciting opportunity to assemble materials with molecular precision. However, there remains unmet need turn self-assembly into functional and devices. Harnessing the inherent properties of both disordered proteins graphene oxide (GO), we report a protein-GO co-assembling system that through diffusion-reaction process disorder-to-order transitions generates hierarchically organized exhibit high stability access non-equilibrium on demand. We use experimental...
An intelligent enantioselective identification strategy is designed to demonstrate that both enantioselectivity and stereoselectivity are crucial factors for chiral sensing.
Understanding the synergism between metal site and acid is of great significance in boosting efficiency bi-functional catalysts many heterogeneous reactions, particularly biomass upgrading. Herein, a "confined auto-redox" strategy reported to fix CeO
A combined experimental-theoretical study on the effect of oxalic acid particle formation and growth from reaction MSA with trimethylamine in absence presence water.
Understanding the properties of atmospheric particles made several components is a very challenging problem. In this paper, we perform quantum chemical calculations for small multicomponent clusters relevance that incorporate methanesulfonic acid (MSA), methylamine (MA), oxalic (OxA), and water (H2O). Potential correlations between theoretical predictions proton transfer in findings recent experiments on formation detectable sizes (>2 nm) from same are studied. It proposed to amine 1:1...
High thermal conductivity of silicon limits its application prospect in thermoelectric technology for direct to electrical energy conversion. Nanostructuring has been demonstrated be an effective approach significantly reducing lattice and hence improving figure merit zT due the enhanced phonon scattering at boundaries. Here, it is shown that fine‐grained (≈800 nm) heavily doped bulk with optimized carrier concentration, electron–phonon also plays important role transport above room...
Chiral enantiomers have different effects on biological processes. Enantiomer separation is significant and necessary. Herein, a photothermal (PT) effect-derived enantioselective desorption strategy based homochiral Au/TiO2 nanotubes (NTs) developed. Using 3,4-dihydroxyphenylalanine (DOPA) as the model enantiomer, an obvious selective of L/D-DOPA can be achieved by NIR light-triggered local temperature enhancement. Molecular docking simulation further verifies that distinct affinity...
To ensure the safe transportation of a 120 m3 liquid hel ium storage tank, based on analysis its structure, material, and load characteristics, finite element model for stress strength is established solved by using coupled thermo-mechanical method accelerating cornering cases experienced tank during transportation. The deformation distributions in different are analyzed comparison to model, check carried out tank. study shows that under various working cases, extreme value some parts 267.5...
Model merging offers an effective way to integrate the capabilities of multiple fine-tuned models. However, performance degradation merged model remains a challenge, particularly when none or few data are available. This paper first highlights necessity domain-specific for by proving that data-agnostic algorithms can have arbitrarily bad worst-case performance. Building on this theoretical insight, we explore relationship between and distillation, introducing novel few-shot algorithm,...

Cooperative behaviors of the hydrogen bonding networks in proteins have been discovered for a long time. The structural origin this cooperativity, however, is still under debate. Here we report new investigation combining excess infrared spectroscopy and density functional theory calculation on peptide analogs, represented by N-methylformamide (NMF) N-methylacetamide (NMA). Interestingly, addition strong bond acceptor, dimethyl sulfoxide, to pure analogs caused opposite effects, namely red-...
