Advanced Functional Materials, EarlyView.A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...

Environmental Consequences of Ethanol from Corn Grain, Ethanol from Lignocellulosic Biomass, and Conventional Gasoline [PDF]
The Energy Policy Act of 2005 includes a provision designed to double the production and use of ethanol in fuels by 2012, and that beginning in 2013, a minimum of 250 million gallons per year of ethanol be produced from lignocellulosic sources such as ...

Cotton Blend Gravity $pp$ Waves [PDF]
, 2004 We study conformal gravity in d=2+1, where the Cotton tensor is equated to a--necessarily traceless--matter stress tensor, for us that of the improved scalar field. We first solve this system exactly in the $pp$ wave regime, then show it to be equivalent

Advanced Functional Materials, EarlyView.Trap state engineering in inverted organic photodetectors (OPDs) is achieved via combined layer‐by‐layer (LbL) processing and poly(N‐vinylcarbazole) (PVK) incorporation. LbL reduces the trap density while PVK additives gradually shift trap states from shallow band‐edge to deep mid‐gap levels, tailoring the energy distribution.

Mechanotransducing Organic Electrochemical Diode for Crosstalk‐Inhibited Artificial Skin
Advanced Functional Materials, EarlyView.An innovative approach is presented to a stretchable mechanotransducing diode that unifies rectification and tactile‐sensing functionality. This approach enables to fabricate the diode that maintains a large rectification ratio (5 × 102) at a high operational frequency (100 Hz).

Advanced Functional Materials, EarlyView.A mechanically tunable hydrogel composed of gelatin, chondroitin sulfate and laminin promotes angiogenesis in vitro without the supplement of growth factors. Endothelial cells morphogenesis was further enhanced by medium conditioned with bioactive glass 58S‐released ions (Ca and Si), thus offering a promising strategy to vascularize 3D tissue ...
