Atomic Size Misfit for Electrocatalytic Small Molecule Activation

open access: yesAdvanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Reflections on gains and losses: A 2x2x7 experiment [PDF]

open access: yes, 2002
We test whether risk attitudes change when losses instead of gains are involved. The study of gain-loss asymmetries has been largely confined to reflected choices, where all the money amounts of a positive prospect are multiplied by minus one.

The gain-loss asymmetry and single-self preferences [PDF]

open access: yes
Kahneman and Tversky asserted a fundamental asymmetry between gains and losses, namely a “reflection effect” which occurs when an individual prefers a sure gain of $ pz to an uncertain gain of $ z with probability p, while preferring an uncertain loss of

Effects of the stellar wind on X-ray spectra of Cygnus X-3

open access: yes, 2008
We study X-ray spectra of Cyg X-3 from BeppoSAX, taking into account absorption and emission in the strong stellar wind of its companion. We find the intrinsic X-ray spectra are well modelled by disc blackbody emission, its upscattering by hot electrons ...

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

open access: yesAdvanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Engineering Porous Hollow Metal‐Poly(Heptazine Imide) Spheres: An Optimized Synthetic Strategy for Controlling Surface, Morphology, and Properties

open access: yesAdvanced Functional Materials, EarlyView.
Hollow poly(heptazine imide) spheres are prepared through a novel approach that integrates hard templating with ionothermal synthesis. This method enables precise control over surface area, pore volume, hydrophilicity, light absorption, band position, and metal composition. These tunable properties facilitate the customized design of semiconductors for

Effect of Mg, Co and Ti Cations on Magnetic and Microwave Properties of SrFe12O19 Nanoparticles

open access: yesJournal of Advanced Materials in Engineering, 2016
Nanoparticles of Mg–Co–Ti substituted strontium hexaferrite with nominal composition of SrFe12-2x(Mg,Co)0.5x TixO19 (x=0-2.5) were synthesized by a co-precipitation method.

Prediction of moisture and temperature changes in composites during atmospheric exposure [PDF]

open access: yes
The effects of variations in diffusion coefficients, surface properties of the composite, panel tilt, ground reflection, and geographical location on the moisture concentration profiles and average moisture content of composite laminates were studied ...

Enhancing Direct Solar Water Splitting via ALD of Multifunctional TiO2/Pt Nanoparticle Coatings With Engineered Interfaces to GaAs/GaInP Tandem Cells

open access: yesAdvanced Functional Materials, EarlyView.
Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.

Application of time-aware retransmission against reflection signal interferences in Internet of things

open access: yes物联网学报, 2019
In the enclosed spaces,wireless transmissions lead to the strong interferences of reflection signals,because of multipath effects.However,how to reduce the reflection signal effect on wireless transmissions is a kernel problem to expand the application ...
