A Reaction‐Diffusion Frame for Accessing Metabolic O2 Fluxes in Single Microalgal Cells with Low‐Cost Wide‐Field Imaging of Nanosensor Luminescence Lifetime

open access: yesAdvanced Science, EarlyView.
Individual Chlamydomonas reinhardtii (C. reinhardtii) living cells on an agarose pad containing luminescent O2 nanosensors are imaged with a simple wide‐field protocol of lifetime imaging. The resulting maps of phosphorescence lifetime are analyzed within a reaction‐diffusion frame to access the distribution of metabolic O2 fluxes generated by single ...

TLS-bridged co-prediction of tree-level multifarious stem structure variables from worldview-2 panchromatic imagery: a case study of the boreal forest [PDF]

open access: yes, 2016
In forest ecosystem studies, tree stem structure variables (SSVs) proved to be an essential kind of parameters, and now simultaneously deriving SSVs of as many kinds as possible at large scales is preferred for enhancing the frontier studies on ...

Enzyme Immobilization by Hydrogen‐Bonded Organic Framework for the Construction of Plant‐Wearable Sensor

open access: yesAdvanced Science, EarlyView.
By modulating the charge of acetylcholinesterase, it is encapsulated within HOF materials, thereby enhancing its stability and maintaining its activity. Subsequently, the composite material is embedded in a glycerol‐sodium alginate gel, achieving the long‐term monitoring of pesticides.

[3]CycloBODIPY: A Highly Strained Cyclic BODIPY Trimer with Effective Macrocyclic Conjugation

open access: yesAngewandte Chemie, EarlyView.
A macrocyclic [3]cycloBODIPY, composed solely of boron‐dipyrromethene (BODIPY) units, was synthesized via gold‐mediated cyclization. Despite its high strain energy (86.4 kcal mol−1), flexible boron centers help disperse the strain. The macrocycle shows near‐infrared (NIR) absorption up to 1050 nm due to BODIPY deformation and extended π‐conjugation ...

Occurrence and Distribution of Cyanobacteria and their Toxins in Silver Lake, New Hampshire [PDF]

open access: yes, 2008
A study of Silver Lake, NH was performed as part of a 5-lake assessment of cyanobacteria prevalence and distribution. Multi-parameter fluorescence probe measurements of chlorophyll a and cyanobacteria concentrations (PC, phycocyanin fluorescence) were ...
