Influence of cadmium on photosynthesis of Brassica campestris ssp. chinensis L
浙江大学学报. 农业与生命科学版, 2005 Effects of different concentrations of Cd on photosynthesis and chlorophyll fluorescence in Pakchoi (Brassica campestris ssp. chinensis L.) were studied in solution culture. The results showed that low concentrations of Cd (0.01, 0.1 mg/L) promoted plant

Rapid colour changes in Euglena sanguinea (Euglenophyceae) caused by internal lipid globule migration [PDF]
, 2018 The accumulation of red pigments under chronic stress is a response observed in most groups of oxygenic photoautotrophs. It is thought that the red pigments in the cell shield the chlorophyll located underneath from the light. Among these red pigments,

Erasable FAP Targeted Spray‐On Probe for Fluorescence‐Guided Surgery
Advanced Science, EarlyView.We present the first erasable spray‐on probe for fluorescence‐guided surgery. Following topical delivery, FAP‐FLASH550 targets fibroblast activation protein–expressing stromal cells, delineating tumor margins with high tumor‐to‐background ratios. A 365 nm UV light pulse rapidly erases fluorescent signals through triazene photodegradation and subsequent

Oxygen isotopic composition of carbon dioxide in the middle atmosphere [PDF]
, 2007 The isotopic composition of long-lived trace molecules provides a window into atmospheric transport and chemistry. Carbon dioxide is a particularly powerful tracer, because its abundance remains >100 parts per million by volume (ppmv) in the mesosphere ...

Photolyzable Polymer Brushes: Subtractive 3D Structuring of Surfaces Using Water and Light
Angewandte Chemie, EarlyView.Facile structuring of polymer brushes is achieved by flipping the process from controlled growth to controlled brush photolysis. Using surface‐initiated radical ring‐opening polymerization of cyclic monomers with photocleavable cyclobutane rings, photodegradable targets are embedded into the polymer chains. The enabled continuous subtractive patterning

Structurally Enhanced Colloidal Molecules via Carbene‐Mediated Covalent C─H Insertion Crosslinking
Advanced Science, EarlyView.This work presents a nonspecific covalent crosslinking strategy to significantly enhance the structural stability of colloidal molecules (CMs) without compromising their inherent structural and physicochemical properties by rationally designing a diazo‐based crosslinker.

The atmospheric chemistry of the warm Neptune GJ 3470b: influence of metallicity and temperature on the CH4/CO ratio [PDF]
, 2013 Current observation techniques are able to probe the atmosphere of some giant exoplanets and get some clues about their atmospheric composition. However, the chemical compositions derived from observations are not fully understood, as for instance in the

Angewandte Chemie, EarlyView.An oil‐in‐water nanoemulsion transforms a boron difluoride formazanate (BDF) dye into a dual‐modal imaging‐guided theranostic agent (BDF‐NE). Its nonpolar oil core maximizes NIR‐II fluorescence while maintaining strong photoacoustic contrast to guide photothermal therapy with high photostability and 66.8% photothermal conversion efficiency, achieving ...
