Aqueous ammonia has been examined as a new weak base for the synthesis of [Au(NHC)Cl] complexes, as well as for the activation of C-H, S-H, and N-H bonds. Its low cost and mild operational conditions (in air and using technical grade solvents) make it an attractive alternative for producing gold-NHC complexes. Synthetic pathways have been investigated , assessing the role of the deprotonation and metalation steps within the reaction mechanisms.

Article Synopsis
  • - The study demonstrates the use of inactivated alkyl boronic acids (BAs) as effective partners in a photocatalyzed Suzuki-Miyaura reaction without needing external activators or strong oxidants.
  • - It proposes a unique activation pathway for BAs involving a radical transfer between a bromine radical and the boron atom's empty p-orbital, which differs from traditional methods that rely on tuning oxidation potential.
  • - The findings are backed by control experiments and density functional theory (DFT) calculations, introducing a new halogen radical transfer (XRT) mechanism for the reaction.

Our cognitive processing is flexible and affected by global/local dominance in prior cognitive tasks. Similar to cognitive processing, perceptual processing, especially colour perception related to global/local processing, may be affected by prior global/local dominance; however, this possibility has not yet been assessed. Here, we examined whether prior tasks involving global/local processing influenced colour perception related to global/local processing.

Circulating tumor cells (CTCs) are tumor cells that originate from primary cancer tissues, enter the bloodstream in the body, and metastasize to the other organs. Simple and convenient methods for their detection, capture, and recovery from the blood of cancer patients would be highly desirable. We report here on a simple and convenient methodology to trap, culture, and re-collect cancer cells, the sizes of which are greater than those of normal hematologic cells, by the use of glass-bead filters (GBFs).

In the field of biological microscopy technology, it is still a practical challenge to obtain high-quality tissue images, due to the tissue desiccation that occurs during observations without an effective sample mounting. Inspired by the use of plastic food wrap, this study proposes the use of polymer thin films (also known as nanosheets) to fix the tissue samples. Water-repellent nanosheets composed of the amorphous fluoropolymer CYTOP are prepared with adjustable thicknesses and their hydrophobicity, transparency, and adhesion strength are evaluated.
