The relationship between yttria concentration and the unit cell parameters in partially fully stabilized zirconia has been reassessed, motivated by need to improve accuracy of phase analysis upon decomposition t′ ‐based thermal barrier coatings. Compositions ranging from 6 18 mol% YO 1.5 were synthesized examined means high‐resolution X‐ray diffraction. Lattice determined using Rietveld refinement method, a whole‐pattern fitting procedure. revised empirical relationships fall within range...
3D printing has become an important strategy for constructing graphene smart structures with arbitrary shapes and complexities. Compared oxide ink/gel/resin based manners, laser-induced (LIG) is unique facile scalable assembly of 1D 2D but still faces size shape obstacles macrostructures.

On the basis selective laser sintering, LIG-AM...
Abstract Sodium (Na) batteries are being considered as prospective candidates for the next generation of secondary in contrast to lithium‐based batteries, due their high raw‐material abundance, low cost, and sustainability. However, unfavorable growth Na‐metal deposition severe interfacial reactions have prevented large‐scale applications. Here, a vacuum filtration strategy, through amyloid‐fibril‐modified glass‐fiber separators, is proposed address these issues. The modified symmetric cell...
Abstract Rechargeable neutral aqueous zinc−air batteries (ZABs) are a promising type of energy storage device with longer operating life and less corrosiveness compared conventional alkaline ZABs. However, the ZABs normally possess poor oxygen evolution reactions (OERs) reduction performance, resulting in large charge–discharge voltage gap low round‐trip efficiency. Herein, we demonstrate sunlight‐assisted strategy for achieving an ultralow 0.05 V by using FeOOH‐decorated BiVO 4 (Fe‐BiVO )...
In situ characterizations of charge injection dynamics, equilibrated concentration, and electric field distributions shed light on the critical mechanisms quantum dot light-emitting diodes (QD-LEDs). this work, we developed electrically excited transient absorption spectroscopy, which can provide above key information, to investigate efficiency roll-off QD-LEDs. We found that average electron populations per QD are low when QD-LEDs exhibit roll-off, excluding Auger recombination as main...
Two-dimensional (2D) metallic transition metal dichalcogenides (MTMDCs) have attracted tremendous interest due to their intriguing physical properties and broad application potential. However, batch production of high-quality 2D MTMDCs based on existing synthesis surfaces remains a huge challenge. Herein, universal synthetic route for the scalable MTMDC (e.g., TaS2, V5S8, NbS2) nanosheets using microcrystalline NaCl crystals as templates via facile chemical vapor deposition method is...
Topological nodal rings can be classified into three types according to the slopes in their energy dispersion. Type-I consist of type-I points, type-II and type-III anisotropic points. Taking carbon networks as an example, we show that all exist transform from one another under experimentally realizable strain. Within a given type, transition between topological metal phase semiconductor also takes place, each type shrinks corresponding semi-Dirac including novel -III These features are...
