Tuning the Electronic Structure and Spin State of Fe─N─C Catalysts Using an Axial Oxygen Ligand and Fe Clusters for High‐Efficiency Rechargeable Zinc–Air Batteries

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 ...

Generating Cell Surface Nucleated Hydrogels with an Artificial Membrane‐Binding Transglutaminase

Advanced Functional Materials, EarlyView.
Cell‐based therapies require advanced strategies to enhance cell delivery and bioactivity. Cell membrane engineering offers an avenue to impart new functions to delivered cells to boost their viability and function. Here, an artificial membrane‐binding transglutaminase is generated and biophysically characterized.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Sodium - A Functional Plant Nutrient

Critical Reviews in Plant Sciences, 2003
Plant scientists usually classify plant mineral nutrients based on the concept of “essentiality” defined by Arnon and Stout as those elements necessary to complete the life cycle of a plant. Certain other elements such as Na have a ubiquitous presence in soils and waters and are widely taken up and utilized by plants, but are not considered as plant ...

Waterlogging and Plant Nutrient Uptake

2010
Waterlogging affects several parameters that determine nutrient uptake from the soil by the roots. We checked systematically, for all the relevant parameters in the nutrient uptake model by Silberbush and Barber (Plant Soil 74:93–100, 1983), how waterlogging changes the magnitude of the parameter, changes that can be both positive and negative for ...

Plant nutrient expression

Journal of Agronomic Education, 1976
ABSTRACTChanging the expression of P and K in fertilizers from the oxide to the elemental basis has long been considered; all other plant nutrients have been expressed on the elemental basis for many years in most countries. A survey was made to determine the current status of the elemental vs. oxide expression of P and K in the USA.

Nutrient Requirements of Plants

Nature, 1968
Nutrient requirement is a simple and useful concept when used in a qualitative sense, but it is much less satisfactory for quantitative comparisons among organisms. Some of the ambiguities and confusion in the present use of the concept are discussed, and more precise descriptions of the relations between nutrients and growth of plants are proposed.

Plant hormones and nutrient signaling

Plant Molecular Biology, 2008
Plants count on a wide variety of metabolic, physiological, and developmental responses to adapt their growth to variations in mineral nutrient availability. To react to such variations plants have evolved complex sensing and signaling mechanisms that allow them to monitor the external and internal concentration of each of these nutrients, both in ...

Plant Nutrient Use

2011
Nutrient absorption, use, and loss by plants are key steps in the mineral cycling of ecosystems. This chapter describes the factors that regulate nutrient cycling through vegetation.
