Fluorescence Tuning of Carbon Dots from Red to Blue via UV‐Induced Photochemical Etching
Advanced Science, EarlyView.A UV‐driven photochemical process enables continuous color evolution of carbon dots from red to blue using a single irradiation parameter. Progressive photoetching restructures graphitic domains and surface states, allowing full visible‐spectrum emission control.

Tailored Synthesis of Doped Non‐Layered Oxide Nanosheets Using Designed Solid‐State Surfactants
Advanced Science, EarlyView.This work reports a solid‐state surfactant templating method that enables precise doping of non‐layered oxide nanosheets. Using ceria and rare‐earth elements as model systems, we established design principles for solid‐state surfactants containing multiple elements.

Adverse Effects of Ammonia on Nitrification Process: the Case of Chinese Shallow Freshwater Lakes
, 2010 Nitrification is a process in which ammonia is oxidized to nitrite (NO (2) (-) ) that is further oxidized to nitrate (NO (3) (-) ). The relations between these two steps and ambient ammonia concentrations were studied in surface water of Chinese shallow ...

SuFEx‐Enabled Reprogramming of Flavonoids for Selective α‐Glucosidase Covalent Inhibition
Advanced Science, EarlyView.Selective inhibition of intestinal α‐glucosidase remains limited by poor enzyme specificity and off‐target metabolic effects. Here, SuFEx click chemistry is used to reprogram natural flavonoids into covalent inhibitors with enhanced α‐glucosidase selectivity and controlled reactivity. This strategy enables effective regulation of carbohydrate digestion
