Obvious enhancement of the total reaction cross sections for $^{27,28}$P with $^{28}$Si target and the possible relavent mechanisms [PDF]

, 2004
The reaction cross sections of $^{27,28}$P and the corresponding isotones on Si target were measured at intermediate energies. The measured reaction cross sections of the N=12 and 13 isotones show an abrupt increase at $% Z=15$.

Nitrate sources and dynamics in a salinized river and estuary : a δ15N-NO₃⁻ and δ18O-NO₃⁻ isotope approach [PDF]

, 2014
To trace NO3- sources and assess NO3- dynamics in salinized rivers and estuaries, three rivers (Haihe River: HH River, Chaobaixin River: CB River and Jiyun River: JY River) and two estuaries (HH Estuary and CJ Estuary) along the Bohai Bay (China) have ...

ISOTOPICALLY EXCHANGEABLE PHOSPHORUS IN SOILS

Journal of Soil Science, 1958
Summary Phosphate residues in the soil were subdivided into three fractions on the basis of isotopic exchange of orthophosphate ions between the soil and the soil solution. It was observed that the total labile phosphorus was a smaller fraction of the total phosphorus in the heavier soils ( c

Mycorrhiza governs plant-plant interactions through preferential allocation of shared nutritional resources: A triple (13C, 15N and 33P) labeling study

Frontiers in Plant Science, 2022
Plant-plant interactions and coexistence can be directly mediated by symbiotic arbuscular mycorrhizal (AM) fungi through asymmetric resource exchange between the plant and fungal partners.

Catalytic Enantioselective Multicomponent Reactions of Sulfoxonium Ylides Enabled by a Formal Rearrangement—A Versatile Entry to Enantioenriched α‐Sulfanyl Carbonyl Compounds

Angewandte Chemie, EarlyView.
A catalytic network embedding a formal rearrangement enables the first catalytic enantioselective multicomponent reaction (MCR) of sulfur ylides. In the presence of a bulky chiral phosphoric acid, the reaction combines sulfoxonium ylides, aldehydes and thiols, and affords synthetically versatile β‐hydroxy‐α‐sulfanyl carbonyl compounds in ...

Iron‐Photocatalyzed C(sp3)–H Phosphonylation of Alkanes

Angewandte Chemie, EarlyView.
Alkyl phosphonates are valuable motifs that can be prepared by phosphonylations of various common functional groups. However, direct phosphonylations of C(sp3)–H bonds are limited to activated positions. Herein, we report an iron‐photocatalyzed phosphonylation of unactivated C(sp3)–H bonds using a novel phosphite radical trap, which is equipped with an
