芝麻蛋白酶法制备工艺优化Optimisation of the enzymatic preparation of sesame protein

open access: yes, 2023
为了提高芝麻蛋白的纯度,以脱脂芝麻粕为原料,采用超声波辅助碱提法耦合碱性纤维素酶和碱性果胶酶酶解技术制备芝麻蛋白。以芝麻蛋白纯度为指标,通过单因素实验对芝麻蛋白的提取工艺条件进行了优化。结果表明,芝麻蛋白制备的最优工艺条件为匀浆处理时间15 min、碱溶时间1.0 h、酶用量0.1%、酶处理超声功率密度0.5 W/cm2、酶解时间2.0 h,在此条件下芝麻蛋白提取率为74.8%,纯度为89.8%,与未耦合酶法提取的芝麻蛋白纯度(75.6%)相比提高了14.2百分点。综上 ...

Synergistic Effect of High Strength‐Grain Refinement and Suppression of Al6Fe Phase Coarsening in Additively Manufactured Al‐Fe‐Sc‐Zr Alloys via Mg Addition

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT To meet the demand for high‐performance lightweight heat‐resistant materials in aerospace and automotive applications, a novel Al‐Fe‐Sc‐Zr heat‐resistant aluminum alloy was fabricated by laser powder bed fusion (L‐PBF). The effects of Mg content (1 wt%, 3 wt%, 5 wt%, and 7 wt%) on formability, microstructure, mechanical properties, and thermal

Ni‐Induced Interface Refinement Enhances Strength‐Ductility Synergy in LPBF‐Processed Ti‐Mo‐Ni Alloy

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Microstructural refinement is a common strategy for strengthening additively manufactured titanium alloys because it promotes phase nucleation. Reducing the α/β interfacial formation energy is an effective way to increase the nucleation rate.

Dual‐Phase Interpenetrating Reinforcement Enables an Ultrathin Sodium Metal Anode for High‐Energy‐Density Batteries

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Ultrathin sodium (Na) metal anodes (< 40 μm) with superior electrochemical performance are essential in developing high‐energy‐density sodium metal batteries (SMBs). Nonetheless, Metallic Na's poor processability hinders its practical application.

Synchronous Ultrasonic Impact Treatment for Regulating Microstructure and Properties of Laser‐Directed Energy Deposited In Situ TiC/Ti6Al4V Composites

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT In laser‐directed energy deposition (LDED) of TiC/Ti6Al4V composites, a low content of micron‐sized TiC provides a good strengthening effect on hardness and strength, but the improvement in plasticity remains a challenge. By introducing synchronous ultrasonic impact treatment (UIT) into the LDED process, an ultrasonic‐assisted LDED (UA‐LDED ...

Laser‐Directed Energy Deposition of Ti2AlNb Alloy: As‐Deposited Ultrahigh Strength and Heat‐Treated Strength–Ductility Balance

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT An ultra‐high as‐deposited tensile strength of 1408 MPa—the highest reported value for laser‐directed energy deposition (L‐DED) fabricated Ti2AlNb alloy—is achieved in this study. The as‐deposited microstructure consists of coarse B2 grains with a high density of fine acicular O phase precipitates within the grains, along with a brittle α2 ...

Synergistic Effect of Hydrophilic Surface and Nano‐Ag2O in TiO2‐Based Composites Coating on Antibacterial and Osteogenic Properties of Low Modulus Ti‐Mo‐Ag Alloy

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Ti‐15Mo‐2.5Ag alloy exhibited a low modulus and strong antibacterial ability but poor bioactivity. To resolve this problem, sandblasting and anodization were used to create a hydrophilic and nano‐Ag2O‐containing TiO2 coating. Subsequently, the microstructure and physicochemical properties were investigated by scanning electron microscopy, X ...
