Engineered Metal–Organic Frameworks‐Based Materials for Environmental Detection

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Engineered metal–organic frameworks (MOFs) regulated by various material modification strategies are discussed for environmental contaminant detection under different sensing mechanisms, providing future improvements of MOFs in environmental detection. Sensitive and selective detection of contaminants is crucial for environmental protection.

The effects of bicarbonate and mineral surfaces on uranium immobilization under anaerobic conditions [PDF]

open access: yes, 2011
For four decades, from 1940 through 1980, the U.S. Department of Energy (DoE) extensively mined and processed uranium at various sites. As a result, widespread uranium contamination exists in subsurface sediments and aquifers.

Hofmann Degradation of Asparagine and Glutamine as an Efficient Approach for the Synthesis of Derivatized Lysine Homologs

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A practical and scalable route to C1 and C2 lysine homologs has been developed using Hofmann degradation of N‐protected L‐asparagine and L‐glutamine as the key step. These short‐tether scaffolds enable efficient synthesis of diverse Fmoc‐protected noncanonical amino acids (ncAAs) bearing donor, acceptor, redox‐active, and fluorescent residues.

Current clinical use of depigmenting agents

open access: yesDermatologica Sinica, 2014
A variety of topical depigmenting agents have been used clinically, with varying degrees of success. To date, the most effective topical treatment is a triple-combination agent containing hydroquinone (HQ), tretinoin, and fluocinolone acetonide. However,

A Novel Type of Fluorescent Chlorophyll Catabolites Hypermodified by Lipophilic Chloroplast Membrane Components

open access: yesHelvetica Chimica Acta, EarlyView.
Breakdown of chlorophyll (Chl) is a fundamental biological phenomenon. In de‐greening banana leaves, Chl is transformed into colorless “fluorescent” Chl‐catabolites (FCCs) that cause the leaves to luminesce blue. Hypothesis‐driven search for apolar banana‐FCCs, and structure elucidation, have revealed a striking first link between lipid metabolism and ...

Glyco‐Nanogels for Modulating Pseudomonas aeruginosa Biofilm

open access: yesMacromolecular Rapid Communications, EarlyView.
Nanogels presenting α‐galactose and β‐fucose can significantly alter Pseudomonas aeruginosa biofilm dynamics through their interaction with lectins. Application timing is crucial: pre‐treatment reduces biofilm, while treatment after biofilm initiation increases biomass.
