Tb 2 O 3 endows Co 3d with a narrow band and appropriate location via 3d–O 2p–Tb 4f gradient orbital coupling to efficiently enhance the oxygen reduction reaction.
Abstract Organic light‐emitting transistors (OLETs) are highly integrated and minimized optoelectronic devices with significant potential superiority in smart displays optical communications. To realize these various applications, it is urgently needed for color‐tunable emission OLETs, but remains a great challenge as result of the difficulty designing organic semiconductors simultaneously integrating high carrier mobility, strong solid‐state emission, ability tunable colors. Herein,...
The use of deep eutectic solvent (DES)-based treatment is a potential solution for the effective disposal heavy-metal-enriched biomass. However, energy-intensive recycling and inefficient reusability DESs hinder industrialization process. Herein, instead DESs, we design novel DES develop simultaneous process including biomass pretreatment conversion obtained into an adhesive. successfully removes approximately 97% Cd from biomass, over 60% lignin, small amount polysaccharides. inclusion...
Semi-macrosegregation in continuously cast blooms and its associated carbide banding defects hot-rolled bars were investigated to explore the characteristics, evolution, control methods high-carbon chromium bearing steel. It was found that semi-macrosegregation exists only central equiaxed crystal zone of blooms, C, Cr solute elements inside show typical spot-like positive segregation. Carbide appears as white bright bands along rolling direction, composed high number density M3C particles,...
As-cast inherited defects are usually observed especially in quenched and tempered (QT) steels, such as 42CrMo due to macro-segregation. A three-dimensional numerical model has been presented reveal the heat mass transportation solidification behaviour of molten steel a 250 mm × 280 continuously cast bloom with without M-EMS application. The reliability coupled was proved by comparing measured data magnetic flux density calculated one along centreline. research indicates that phenomena...

Social equity/inequity and equal/unequal rights to the city extend beyond distribution of urban parks green spaces, necessitating research on equitable accessibility encompass a broader range public spaces. However, previous has predominantly focused neglecting other types To address this gap, present study takes space pattern Nanjing Old City as object, employing minimum distance method, gravity potential bivariate local Moran’s I evaluate matching relationship between demand socially...
Plasmonic devices using periodic metallic nanostructures have recently gained tremendous interest for color filters, sensing, surface enhanced spectroscopy, and photoluminescence, etc. However, the performance of such plasmonic is severely hampered by solid substrates supporting nanostructures. Here, a strategy freestanding nanomembranes introduced taking advantages hollow substrate structures. Large-area highly uniform gold with nanohole array are fabricated via flexible simple...
We present a segmented coupling model for slab casting by roller electromagnetic stirring (R-EMS) of electromagnetic, flow, heat transfer, and solidification behavior based on magnetohydrodynamics theory. A three-dimensional (3-D) that included transfer elements was established using Ansoft Maxwell ANSYS Fluent software. The effects the sleeve, magnetic shielding ring, coil, core, molten steel, air domain thermal flow fields were studied numerically. accuracy verified measuring flux density...

Abstract The projection environment and operational characteristics of new types munitions, such as loitering munitions drones, differ significantly from those conventional munitions. These are characterized by a weaker environment, longer cruise times, secondary strike capabilities. Current fuze safety system design methods no meet these requirements. Therefore, it is necessary to propose for calculating failure rates ensure the reliability system. In this paper, aiming at recoverable...
With the rise of sports technology industry, it has become a global trend to combine science with technology. We can monitor movement load and confirm correctness key claims through wearable devices action identification system, in order improve performance players, search reduce controversy competition. Therefore, fast-paced table tennis match, how replace traditional way sentiment intervention is topic worth discussing. Objective: To accuracy lovers serve receiving self-made marking...
