Integrated Capture and Electroreduction of Low‐Concentration CO2 to CO Using Geopolymer|Graphene‐Cobalt Phthalocyanine Composite

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
A highly efficient e‐CO2RR platform for efficient and selective CO production from the electroreduction of the low‐concentration CO2 in the simulated biogas is successfully established. This platform is created for the first time using geopolymer‐encapsulated graphene‐supported cobalt phthalocyanine.

Demonstration of a new indicator for studying upwelling in the northern South China Sea

open access: yesOceanologia, 2011
In order to demonstrate that silicate can be used as an indicator to study upwelling in the northern South China Sea, hierarchical cluster analysis (CA) and principle component analysis (PCA) were applied to analyse the metrics of the data consisting of ...

Bulk and Surface Reactivity of LiNi0.5Mn1.5O4 in Contact with (Acidic) Water

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The comprehensive investigation of the influence of (acidic) water on LiNi0.5Mn1.5O4 as cobalt‐free lithium‐ion battery cathode material reveals that such treatment particularly affects a very thin layer at the particle surface, while the bulk material remains unaffected.

Memory Effect of Bacteria‐Killing Properties of Piezo‐Catalysts Nanomaterials through Defect Engineering

open access: yesAdvanced NanoBiomed Research, EarlyView.
It was discovered by Omid Amiri and co‐workers that piezo‐catalysts or piezo materials exhibit an intriguing memory effect in their ability to kill bacteria. The effect is that the piezo materials can retain their activity even days after the mechanical force has been applied. The piezo‐catalysts can preserve their ability to kill bacteria for up to 11

Mn2+‐Activated Alkali Lithooxidosilicate Phosphors as Sustainable Alternative White‐Light Emitters

open access: yesAngewandte Chemie International Edition, EarlyView.
Eu2+‐activated alkali lithooxidosilicates are celebrated phosphor materials. We showed for the first time that the alternative, more abundant transition metal ion Mn2+ can also be incorporated into those compounds. The phosphors show two emission bands (green and red), making them interesting candidates for pc‐wLEDs with only one converting phosphor ...
