Solar Flow Synthesis of Polymer Nanoparticles: Scaling Local Experiments to Global Potential

open access: yesAngewandte Chemie, EarlyView.
The large‐scale sunlight‐induced photochemical synthesis of polymer nanoparticles based on the Diels–Alder step‐growth polymerization of a bismaleimide and a difunctional o‐methylbenzaldehyde in a self‐built solar flow reactor is introduced. Furthermore, a framework is established to translate sunlight‐driven experimental results globally—validated in ...

The "Yin-Yang Grid": An Overset Grid in Spherical Geometry

open access: yes, 2004
A new kind of overset grid, named Yin-Yang grid, for spherical geometry is proposed. The Yin-Yang grid is composed of two identical component grids that are combined in a complemental way to cover a spherical surface with partial overlap on their ...

Biodegradation of aromatic compounds by high latitude phytoplankton [PDF]

open access: yes, 1982
"It was the purpose of the work undertaken to bring into pure culture representative diatoms from the Cook Inlet and the ice-edge in the Bering Sea and to examine their capacity for the oxidation of aromatic compounds using naphthalene as a model ...

Compartmentalized Homeostasis Drives High Bamboo Forest Productivity under Nutrient Imbalance

open access: yesAdvanced Science, EarlyView.
This study reveals how Moso bamboo achieves high productivity despite nutrient‐poor soils. It employs a unique strategy, maintaining strict nutrient balance in its leaves while using woody tissues as flexible storage reservoirs. This compartmentalized mechanism buffers the plant from soil phosphorus limitation and microbial competition, resolving the ...

Differential rotation measurement of soft X-Ray corona

open access: yes, 2010
The aim of this paper is to study the latitudinal variation in the solar rotation in soft X-ray corona. The time series bins are formed on different latitude regions of the solar full disk (SFD) images that extend from 80 degree South to 80 degree North.

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate

open access: yesAdvanced Science, EarlyView.
We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought
