A Novel Two‐Stage Flexible Flow Shop Batch Scheduling Model for Grinding Workshops

Naval Research Logistics (NRL), EarlyView.
ABSTRACT The growing need for data storage in data centers has increased the demand for mechanical hard disks due to their low cost and high reliability. Aluminum substrates are the most popular base plates for mechanical hard disks because of their high hardness and low cost.

Sodium Induced Beneficial Effects in Wide Bandgap Cu(In,Ga)S2 Solar Cell With 15.7% Efficiency

Progress in Photovoltaics: Research and Applications, EarlyView.
Wide bandgap Cu(In,Ga)S2 absorbers grown on soda‐lime glass (SLG) were optimized by introducing additional sodium (Na) via in situ NaF co‐evaporation. Optimal Na incorporation enhanced crystallinity, minimized Ga fluctuations across the depth, suppressed bulk defects, and reduced non‐radiative losses.

Synergistic Anode/Cathode Optimization Engineering by Hierarchical Porous N‐Doped Carbon Fibers for Efficient Zinc Batteries

Rare Metals, EarlyView.
ABSTRACT The poor Zn chemistry of Zn metal anode and sluggish reaction kinetics of cathodes at high mass loadings are two crucial issues for hindering the application of aqueous Zn‐ion batteries (AZIBs). Herein, the hierarchical porous N‐doped carbon fibers (HPNCFs) were proposed to simultaneously optimize the reversibility of Zn plating/stripping of ...

The Dependence of Properties on Structural Features in Macro/Micro Levels for PBF‐LB Fabricated Porous NiTi Alloy

Rare Metals, EarlyView.
ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...

Twin‐Wire In Situ Additive Manufacturing of NiTiNb Eutectic Alloys: Eliminating Unmelted Nb Particles and Tailored Superelasticity

Rare Metals, EarlyView.
ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...
