Water‐Dispersible Ruthenium Nanocatalyst for Carbonyl Reduction With D2 or T2 in Aqueous Media
Angewandte Chemie, EarlyView.We report the synthesis and characterization of water‐dispersible ruthenium nanoparticles that catalyze the reductive deuteration and tritiation of carbonyl compounds in aqueous media, enabling efficient access to a broad range of isotopically labeled polar molecules, including cyclic peptides, antibody‐drug conjugate linkers, pegylated derivatives ...

Ore Geology Reviews, 2011 Abstract The Taoxikeng tungsten deposit is located in the Jiangxi Province in the southern part of China, and is one of the largest wolframite quartz-vein type tungsten deposits in the country. The deposit is situated in Sinian (Neoproterozoic) to Permian strata at the contact with the buried Taoxikeng Granite.

Annals of Neurology, EarlyView.Objective Drug‐resistant epilepsy (DRE) remains a clinical challenge, as therapies modifying disease trajectory are lacking. Increasing evidence implicates gut microbiota dysbiosis in epilepsy pathophysiology, with short‐chain fatty acids (SCFAs) emerging as key microbial metabolites with neuroprotective and anti‐inflammatory properties.

APPLICATIONS OF THE RE-OS ISOTOPIC SYSTEM IN THE STUDY OF MINERAL DEPOSITS: GEOCHRONOLOGY AND SOURCE OF METALS [PDF]
, 2005 In mineral deposits the application of the Re-Os system has evolved on two fronts; as a geochronometer in molybdenite, and as a tracer of the source of metals by direct determination of the source of Os contained in the ore minerals.

Angewandte Chemie, EarlyView.State‐of‐the‐art synthesis of radiolabelled oligonucleotides involves multi‐step synthesis with high costs, extended timelines and significant radioactive waste generation. Herein, a dual‐methyltransferase platform enables late‐stage, site‐specific labelling, overcoming these limitations through reduced costs, faster turnaround and minimal radioactive ...

Dual Activation of H2 and CO2 by a Pincer‐Type Ni–Zn Heterobimetallic Complex
Angewandte Chemie, EarlyView.A bimetallic Ni−Zn complex performs sequential activations of H2 (1 equiv) and CO2 (2 equiv). This bimetallic cooperativity is attributed to the weak Lewis acidic nature of Zn(II), which promotes fluxional ligand binding. Namely, an X‐type ligand at Ni, where X is hydride or formate, toggles between two different binding modes: bridging Zn(μ‐X)Ni and ...

Angewandte Chemie, EarlyView.A critical step, dry reforming of methane (DRM) converts biogas into useful syngas. Yet trace H2S in biogas rapidly poisons DRM catalysts, limiting practical use. We developed a robust Pt/CeO2 catalyst sustaining DRM activity via CO2‐induced reverse lattice oxygen spillover in H2S‐rich environments.

In situ Pb-Pb isotopic dating of sulfides from hydrothermal deposits: a case study of the Lala Fe-Cu deposit, SW China [PDF]
, 2019 Precisely dating different generations of mineralization is important for understanding the origin and tectonic environment of ore formation. In this study, we have dated two generations of sulfides from the Lala Fe-Cu deposit, SW China, using in situ Pb-

Ore Geology Reviews, 2019 Abstract The Ashele Cu-Zn deposit, an important volcanogenic massive sulfide (VMS) deposit, is located in the centre of the Ashele volcano-sedimentary basin of the Altay metallogenic belt, North Xinjiang, NW China. The No. 1 orebody is located between the roof basalt and the base tuff. The roof basalt yielded a zircon U-Pb age of 342 ± 4.6 Ma (MSWD =
