Trace element ratios in arc magmas are widely used to infer petrogenetic conditions, particularly those associated with porphyry-forming versus barren systems. However, quantitatively linking whole-rock signatures to pressure, water content, or redox conditions remains challenging, as trace eleme...

A series of bis(trifluoromethyl)amido coinage metal(I) complexes were synthesized in yields of 52-93%. This includes N-heterocyclic carbene (NHC) complexes of copper(I), silver(I), and gold(I). In addition, the complex [(Ph3P)Au{N(CF3)2}] was obtained in 70% yield. The complexes are thermally rob...

Colorectal cancer (CRC) exhibits high mortality due to tumor cell dissemination. Surgical resection combined with chemotherapy is the primary treatment, but chemoresistance often limits its efficacy against metastasis. Cuproptosis, a novel cell death mechanism regulating mitochondrial and lipid m...

We have reported perylene tetra-(alkoxycarbonyl) (PTAC) derivative PTE-EA functionalized with tetraoctylester chains at the peri-positions and an electron-donating group 2-aminoethanol (2-AE) at the mono bay-position. PTE-EA showed colorimetric and fluorescence turn-on response for detection of c...

Gastric cancer remains one of the most common and deadly malignancies worldwide. Trace elements are gaining increasing interest due to their dual roles as both essential nutrients and potential carcinogens. This study aimed to compare trace element concentrations in gastric cancer tissues with he...

Cross-coupling of aryl boronic esters forms a cornerstone of how chemists make molecules. More recently, enantiomerically enriched boronic esters have shown great promise in modular synthesis as versatile building blocks for the rapid construction of diverse molecules. A significant challenge in ...

The toxic effect of zinc oxide (ZnO NPs) and copper oxide (CuO NPs) nanoparticles on natural communities of Black Sea picophytoplankton was investigated during a year-long cycle of in-situ experiments. The results revealed pronounced seasonal and taxonomic specificity of toxicity. It was establis...

This work reports a copper-catalyzed enantioselective S-alkylation of sulfenamides enabled by an amino-radical-transfer deboronation pathway. Chiral sulfilimines are obtained in high yields (up to 95%) and enantioselectivities (up to 98% ee) under mild conditions. An isomerizable bis(oxazoline) l...

At the micro-scale channel dimensions and relatively low Reynolds numbers, fluids can only mix through diffusion in a laminar flow state. This dependence on molecular diffusion significantly hinders the mixing performance of microfluidic chips. To address this issue and promote the application of...
