Thiol-Enhanced Interfacial and Internal Deposition of Metal-Polyphenol Networks for Permanent Hair Dyeing.

Metal polyphenolic networks (MPNs) are becoming more and more attractive for nontoxic hair dyeing, but their coloring effect is not satisfactory because of the limited interfacial deposition and the absence of internal deposition. Moreover, there is a lack of understanding of the driving factors of the interfacial deposition of MPNs on hair. Herein, we develop a simple yet efficient strategy that transforms disulfide bonds of the hair into thiol groups by thioglycolic acid (TGA) to highly enhance the coloring effect of MPNs at a low temperature.

Twelve-hour ultradian rhythmic reprogramming of gene expression in the human ovary during aging.

Background: The 12-h ultradian rhythm plays a crucial role in metabolic homeostasis, but its role in ovarian aging has not been explored. This study investigates age-related changes in 12-h rhythmic gene expression across various human tissues, with a particular focus on the ovary.

Methods: We analyzed transcriptomic data from the GTEx project to examine 12-h ultradian rhythmic gene expression across multiple peripheral human tissues, exploring sex-specific patterns and age-related reprogramming of both 12-h and 24-h rhythmic gene expression.

Surface curvature-driven adsorption-reduction mechanism over hollow N-doped carbon enhances recovery of precious metal ions from wastewater.

The recovery of precious metal ions (PMI) from wastewater has great significances from both economic and environmental perspectives. However, current recovery methods face limitations, including low efficiency and selectivity, as well as challenges in practical applications. In this study, hollow N-doped carbon spheres (HNC) are proved to be promising for improving anionic AuCl and PdCl recovery via the curvature effect, outperforming non-curved carbon (commercial active carbon and carbon nanosheet) due to their unique curvature effect.

Thianthrenium-Enabled Chromium-Catalyzed Deuterated Alkyl Addition to Aldehydes via a Photoactive Electron Donor-Acceptor Complex.

The Nozaki-Hiyama-Kishi reaction offers effective and reliable strategies for the preparation of alcohols via carbon-carbon bond formation. Typical methods usually require stoichiometric amounts of chromium salts, co-transition metals, and auxiliary reagents, which limits their practical application in industrial chemistry. To mitigate these limitations, substantial efforts have been made to develop chromium-catalytic approaches.

Jan and mini-Jan, a model system for potato functional genomics.

Potato (Solanum tuberosum) is the third-most important food crop in the world. Although the potato genome has been fully sequenced, functional genomics research of potato lags behind that of other major food crops, largely due to the lack of a model experimental potato line. Here, we present a diploid potato line, 'Jan,' which possesses all essential characteristics for facile functional genomics studies.
