2′-Deoxynucleosides and analogues play a vital role in drug development, but their preparation remains significant challenge. Previous studies have focused on β-2′-deoxynucleosides with the natural β-configuration. In fact, isomeric α-2′-deoxynucleosides also exhibit diverse bioactivities even better metabolic stability. Herein, we report that both α- can be prepared high yields stereoselectivity using remote directing diphenylphosphinoyl (DPP) group. It is particularly efficient to prepare...
Two high-pressure stable phases (I41/a-CeN4 and R3̅m-CeN6) two metastable (P6mm-CeN14 P6mm-CeN17) were proposed in Ce–N compounds at 150–300 GPa. The polymeric nitrogen units include quadruple helical chains, N6 rings, first reported layered molecular sieves structures. I41/a-CeN4 can be quenched to ambient conditions its thermal stability maintained up 500 K. P6mm-CeN14 is dynamically mechanically pressure. electronic properties analyses show that charge transfer between the Ce N atoms...
Activation of disulfides with N-halogen succinimide in the presence TEMPO allows insertion reaction by an isocyanide, product which can further accept a wide range nucleophiles for generation isothioureas and related molecular moieties. This new procedure overcomes previous methods that essentially only aryl amines as third nucleophilic component. The diverse usable our protocol make this approach general method de novo synthesis many S-containing heterocycles.
Differences in microstructure can often lead to large differences mechanical properties. Here, the composition, microstructure, and properties of mussel, scallop, ostreidae were researched. And subsequently, three bionic models designed based on microstructures shellfish. Three prepared by printing substrate with light-cured resin filling carbon fiber reinforced epoxy resin. The reinforcement mechanisms also investigated. bending fracture force, compression fracture, impact energy mussels...
We argue that the axionic domain-wall with a QCD bias may be incompatible NANOGrav 15-year data on stochastic gravitational wave (GW) background, when domain wall network collapses in hot-quantum chromodynamics (QCD) induced local <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:mi>C</a:mi><a:mi>P</a:mi></a:math>-odd domain.

The Ag-N system is enriched by proposing four polymeric structures in first-principles calculations at high-pressure. proposedP-1-AgN2andP21/c-AgN2not only break the new record configuration of MN2compound, but also energy density. In MN2stoichiometric ratio, infinite armchair-antiarmchair chain and layered polymer structure are reported for first time inP-1-AgN2andP21/c-AgN2, indicating that highly polymerized can be formed nitrides with low nitrogen content high pressure. mechanism...
Abstract Stable inheritance of DNA N 6 -methyladenine (6mA) is crucial for its biological functions in eukaryotes. Here, we identify two distinct methyltransferase (MTase) complexes, both sharing the catalytic subunit AMT1, but featuring AMT6 and AMT7 as their unique components, respectively. While complexes are jointly responsible 6mA maintenance methylation, they exhibit enzymology, DNA/chromatin affinity, genomic distribution, knockout phenotypes. complex, high MTase activity...

Natural colloids are widely distributed in soil and groundwater. Due to their specific characteristics, can actively involve various transport contaminants, resulting a complicated fate the of heavy metals environment. This study investigated effects on adsorption Ni2+ saturated porous media under different conditions, including pH, ion strength (IS), humic acid (HA), because these indexes non-negligible fates organic or inorganic matters subsurface The results indicate that by slightly...
