Confinement‐Induced Metastable Supramolecular Assembly: Dynamic Built‐in Electric Field Driving Deep Mineralization of Organic Pollutants

open access: yesAdvanced Science, EarlyView.
Utilizing the 2D confined space of layered double hydroxide (LDH), living supramolecular assembly (LSA) are successfully prepared with smaller intermolecular distances than in crystals. The IEF enhancement value can reach 11.8 times, which induces a charge separation efficiency of 71.52%.

Measuring Leaf Chlorophyll Concentration from Its Color: A Way in Monitoring Environment Change to Plantations

open access: yes, 2013
Leaf colors of a plant can be used to identify stress level due to its adaptation to environmental change. For most leaves green-related colors are sourced from chlorophyll a and b. Chlorophyll concentration is normally measured using a spectrophotometer
