Fire-derived phosphorus fertilization of African tropical forests
...
Published in Nature Communications
Nowhere is biomass burning more abundant than on the African continent, but the biogeochemical impacts on forests are poorly understood. Here the authors show that biomass burning leads to high phosphorus deposition in the Congo basin, which scales with forest age as a result of increasing canopy complexity.
Au Hierarchical Nanostructure-Based Surface Modification of Microelectrodes for Improved Neural Signal Recording
...
Microelectrodes are widely used for neural signal analysis because they can record high-resolution signals. In general, the smaller the size of the microelectrode for obtaining a high-resolution signal, the higher the impedance and noise value of the electrodes. Therefore, to improve the signal-to-noise ratio (SNR) of neural signals, it is importan...
Atomically Conformal Metal-Laminations on Plasmonic Nanocrystals for Efficient Catalysis
...
Despite the enormous application potential, methods for conformal few-atomic-layer deposition on colloidal nanocrystals (NCs) are scarce. Similar to the process of lamination, we introduce a "confine and shine" strategy to homogeneously modify the different surface curvatures of plasmonic NCs with ultrathin conformal layers of diverse catalytic nob...
Photonic Multilayer Structure Induced High Near-Infrared (NIR) Blockage as Energy-Saving Window
Energy-saving window that selectively blocks near-infrared (NIR) is a promising technology to save energy consumption. However, it is hard to achieve both high transmittance in visible light and high reflectance in NIR for the energy-saving windows. Here, a TiO2/Ag/TiO2/SiO2/TiO2 multilayer is demonstrated on a glass substrate to selectively block ...
Competitive Binding-Modulated Metal-Phenolic Assemblies for Adaptable Nanofilm Engineering
Coordination-driven metal-phenolic assembly, a mechanism associated with many essential biological functions, is being actively exploited for engineering of advanced materials. However, a critical challenge remains in the regulation of the dynamic metal-phenolic networks to overcome the kinetic trapping for well-controlled nanofilm formation. This ...

Following spatial A beta aggregation dynamics in evolving Alzheimer's disease pathology by imaging stable isotope labeli...
...
β-Amyloid (Aβ) plaque formation is the major pathological hallmark of Alzheimer's disease (AD) and constitutes a potentially critical, early inducer driving AD pathogenesis as it precedes other pathological events and cognitive symptoms by decades. It is therefore critical to understand how Aβ pathology is initiated and where and when distinct Aβ s...
Melt pool oxidation and reduction in powder bed fusion
In this work, the mechanism of melt pool oxidation and reduction during the powder bed fusion was studied. To elucidate the mechanism, the effect of process parameters such as laser power, scan speed and shield gas flow speed on the variation on oxygen, nitrogen and carbon content in the printed material was investigated. In 316L stainless steel, m...
CoSe2/MoS2 Heterostructures to Couple Polysulfide Adsorption and Catalysis in Lithium-Sulfur Batteries(dagger)
Main observation and conclusion Lithium-sulfur batteries have been regarded as one of most promising next-generation energy storage devices because of their high energy density and low cost. However, polysulfide shuttling and slow kinetics hinder the practical application. We fabricated hierarchically heterostructured CoSe2/MoS2 nanoarrays on carbo...
