A new computer program, called SHIFTX2, is described which capable of rapidly and accurately calculating diamagnetic (1)H, (13)C (15)N chemical shifts from protein coordinate data. Compared to its predecessor (SHIFTX) other existing shift prediction programs, SHIFTX2 substantially more accurate (up 26% better by correlation coefficient with an RMS error that up 3.3× smaller) than the next best performing program. It also provides significantly coverage 10% more), faster 8.5×) a wider variety...
Copper nanoparticle-based catalysts have been extensively applied in industry, but the nanoparticles tend to sinter into larger ones chemical atmospheres, which is detrimental catalyst performance. In this work, we used dealuminated Beta zeolite support copper (Cu/Beta-deAl) and showed that these particles become smaller methanol vapor at 200°C, decreasing from ~5.6 ~2.4 nanometers diameter, opposite general sintering phenomenon. A reverse ripening process was discovered, whereby migratable...
Hydroformylation is one of the largest industrially homogeneous processes that strongly relies on catalysts with phosphine ligands such as Wilkinson's catalyst (triphenylphosphine coordinated Rh). Heterogeneous for olefin hydroformylation are highly desired but suffer from poor activity compared catalysts. Herein, we demonstrate rhodium nanoparticles supported siliceous MFI zeolite abundant silanol nests very active hydroformylation, giving a turnover frequency high ~50,000 h-1 even...
Porphyrin-based donor–acceptor COFs are effective heterogeneous photocatalysts for photoinduced electron transfer-reversible addition–fragmentation chain transfer (PET-RAFT), including aqueous polymerizations and under red-light excitation.
The hydrogenation of CO2 to methanol, which is restricted by water products, requires a selective removal from the reaction system. Here, we show that physically combining hydrophobic polydivinylbenzene with copper catalyst supported silica can increase methanol production and conversion. Mechanistic investigation reveals promoter could hinder oxidation surface water, maintaining small fraction metallic species on abundant Cuδ+, resulting in high activity for hydrogenation. Such mixed...
Two-dimensional (2D) covalent-organic frameworks (COFs) with a well-defined and tunable periodic porous skeleton are emerging candidates for lightweight strong 2D polymeric materials.

In addition, protons also stabilize product against deprotonation that causes decomposition. productivity reached 320 mmol...
Abstract Formation and preservation of extremely high-pressure fluid in sedimentary basins is critical to understanding petroleum accumulation basin evolution; however, this issue remains poorly understood due a lack key evidence. We present inclusion evidence from the Paleozoic black shales eastern Sichuan Basin (South China block) that suggest gas generation can form methane-saturated fluids with pressures significantly exceeding lithostatic pressure. The internal pressure so high (e.g.,...
