A sophisticated molecular barrel 5 was efficiently constructed by hooping a 63-membered loop around D3h-symmetric, shape-persistent bis(tetraoxacalix[2]arene[2]triazine) core. The strategy involved 3-fold ring-closing metathesis (RCM) reactions of six branched olefin arms which were preanchored on the inner Through hooping, tightens cage structure and significantly enhances its stability toward nucleophilic decomposition. X-ray crystal showed bears three enclosed fan-shaped cavities as...
The Jiaodong gold deposits are currently the most important resources (with Au reserves of >4000 t) in China, and leading gold-producing country globally production ∼428 t 2013). is also considered as perhaps only world-class to giant accumulation on planet where relatively young ores (ca. 130–120 Ma) were deposited rocks that 2 Ga older. Xincheng high-grade deposit, with a proven reserve >200 gold, one largest province Peninsula. It located northwestern part Jiaobei Uplift, hosted by ca....
Abstract Gas hydrates represent a huge reservoir of methane in marine sediments, prone to dissociation response environmental changes. There is consensus that past events gas hydrate the environment mainly occurred during periods low sea level. Here, we report geochemical data for 2‐m‐thick layers seep carbonate collected from hydrate‐bearing drill core ~800‐m water depth northern South China Sea. The aragonite‐rich carbonates reveal positive δ 18 O values, confirming genetic link with...
After nearly 20 years of exploration, various areas the seafloor with hydrocarbon seepage have been discovered in South China Sea (SCS). Through linking subsurface and biospheres, seeps become natural laboratories to enhance our knowledge on processes migration associated hydrocarbon-based ecosystems marine environment. This review summarizes distribution macrofauna active seep SCS describes physiological characteristics three groups representative (bathymodioline mussels, pliocardiine...
This study focused on the Hualiangting Reservoir Basin in Taihu County, where 42 well water samples and 20 spring were collected to measure primary hydrochemical indicators. Using a comprehensive suite of methods including mathematical statistics, Piper diagrams, Gibbs ion ratios, factor analysis, examined characteristics influencing factors within area. Water quality was assessed based entropy-weighted index （EWQI）, potential risks associated with nitrate （NO3-） levels groundwater evaluated...
The D Oilfield in the Songliao Basin has entered a critical phase of hydrocarbon exploration targeting Quantou Formation. However, challenges persist achieving precise stratigraphic division, sedimentary cycle characterization, and microfacies prediction. This study aims to enhance resolution prediction accuracy address uncertainties sand body distribution within dense well pattern areas. Integrated Pattern Recognition Fuzzy Analysis (INPEFA) was applied natural gamma logging data from 4,215...
Abstract At marine methane seeps, siboglinid tube worms influence the exchange of elements between sediments and seawater potentially represent a recorder seep activity. The organ siboglinids produces chitin wall, facilitating formation tubes that protect siboglinid's soft tissue. However, mechanisms underlying element transfer isotope fractionation tissue chitinous are poorly constrained. This study analyzes carbon, nitrogen, sulfur isotopes as well trace elements, including rare earth...
The C(sp2)-C(sp3) cross-coupling reaction is an effective way to increase the C(sp3) content in compound collections for drug discovery, enhancing molecular diversity and offering a unique chemistry starting point. In this study, we report mild, DNA-compatible, off-DNA-inert photochemical inspired by amino radical transfer strategy. This method demonstrates broad substrate scopes DNA-encoded library (DEL) constructions, utilizing commonly available structures on DNA diverse alkyl boronate...
Methane is an important greenhouse gas whose emissions into the oceans and atmosphere are regulated by relatively unconstrained anaerobic aerobic microbial processes.The pathway for methane oxidation thought to be largely dependent upon use of rare earth elements (REE), but date effects this process on their abundances in bacteria or organisms living symbiosis with methanotrophs remain evaluated.Here we show that deep sea chemosynthetic mussels prospering at seeps display distinctive...
Methane hydrates are widely distributed along continental margins, representing a potential source of methane to the ocean and atmosphere, possibly influencing Earth’s climate. Yet, little is known about response global climate change, especially at timescale glacial-interglacial cycles. Here we present chronology seepage from seep carbonates derived series tens hundreds meters long hydrate-bearing sediment records South China Sea, drilled water depths 664−871 m. We find that six out seven...
Heavy-metal pollution has become a serious problem in the vicinity of mining sites. In this study, we investigated degree and spatial distribution heavy metals determined their sources soil near typical Pb/Zn smelter an arid area northwest China. The degree, source identification were evaluated analyzed by geo-accumulation index (Igeo), enrichment factor (EF), ArcGIS-based kriging interpolation models multivariate statistical techniques. results showed that average concentrations Pb, Zn, Cd...
A suitable hygrothermal environment is imperative for sustainably conserving movable and immovable cultural heritage. This paper proposes a combined method quantitatively assessing water-related deterioration risks in heritage buildings, validated employing the Forbidden City China, UNESCO World Heritage site. The approach emphasizes combining coupled transfer simulation with conventional environmental monitoring systematic risk assessments. Key findings include identifying predominant...
Aspersteroids A and B are novel ergostane-type 18,22-cyclosterols with immunosuppressive antimicrobial activities. Herein, we report the first synthesis of these two natural products, which was accomplished in 15 14 steps, respectively, from commercially available ergosterol by means a bioinspired divergent approach. Key features this include an unprecedented radical relay cyclization that initiated iron(II)-mediated decomposition alkyl hydroperoxide to construct E ring cyclopentane motif;...
