In this article, we report a 3D NiFe phosphite oxyhydroxide plastic electrode using high-resolution digital light processing (DLP) 3D-printing technology via induced chemical deposition method. The as-prepared 3D plastic electrode exhibits no template requirement, freedom design, low-cost, robust, anticorrosion, lightweight, and micro-nano porous characteristics. It can be drawn to the conclusion that highly oriented open-porous 3D geometry structure will be beneficial for improving surface catalytic active area, wetting performance, and reaction-diffusion dynamics of plastic electrodes for oxygen evolution reaction (OER) catalysis process. Density functional theory (DFT) calculation interprets the origin of high activity of NiFe(PO3)O(OH) and demonstrates that the implantation of the -PO3 can effectively bind the 3d orbital of Ni in NiFe(PO3)O(OH), lead to the weak adsorption of intermediate, make electron more active to improve the conductivity, thereby lowing the transform free energy of *O to *OOH. The water oxidization performance of as-prepared 3D NiFe(PO3)O(OH) hollow tubular (HT) lattice plastic electrode has almost reached the state-of-the-art level compared with the as-reported large-current-density catalysts or 3D additive manufactured plastic/metal-based electrodes, especially for high current OER electrodes. This work breaks through the bottleneck that plagues the performance improvement of low-cost high-current electrodes.

Ltd.

The compromised egg quality and leg abnormality during the end of the laying cycle(after 40 weeks)have been leading to poor animal welfare and substantial economic losses. Therefore, the effects of fermented calcium(Ca) butyrate, produced by fermentation by Clostridium butyricum, on production,eggshell quality, and tibial property of hens were explored. A total of 192 Hy-line brown laying hens at50-week-old were assigned to a basal diet or the basal diet with 300 mg/kg of the fermented Ca butyrate from 50 to 58 weeks of age. Each treatment had 6 replicates with 16 hens each. The diet supplemented with 300 mg/kg fermented Ca butyrate notably increased egg weight, ovarian follicle number, and eggshell strength(P = 0.072) as compared to the basal diet, which were associated with cytokine secretion, toll-like receptor signaling pathways, and intestinal immunity based on the RNA-seq data from the granulosa. Dietary Ca butyrate inclusion decreased the expression of ileal tumor necrosis factor-alpha and serum pro-inflammatory cytokine concentration, as well as increased the content of serum immunoglobulin A when compared to the basal diet(both P 0.05). In addition, the diet with fermented Ca butyrate reduced the number of osteoclasts in the proximal tibia and the level of C-terminal cross-linked telopeptide of type I collagen, a bone resorption marker(P yield load, and ultimate load than those that consumed basal diets. Collectively, dietary fermented Ca butyrate supplementa
