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 ...

Interface‐Stabilized Glass‐Ceramic/Silver Composite Coatings Enable Predictable Multiband Infrared Stealth Under High‐Temperature Marine Environment

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Infrared (IR) stealth is crucial for improving the survivability of equipment. The growing demand for service in marine environments poses new challenges to the composition and structural design of existing IR stealth coatings. This study first investigates the effects of NaCl/water vapor corrosion on the IR stealth performance of GH3536 and a

Heterointerfaces and Sulfur Vacancies in MXene/MoS2@C for Boosted Ultra‐Broadband Electromagnetic Wave Absorption and Infrared Stealth Response

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Ti3C2Tx MXene shows significant potential in the field of electromagnetic wave absorption; however, the wave absorption performance was hindered due to the impedance mismatch, which was caused by its inherent high dielectric constant. In this work, Ti3C2Tx MXene co‐assembled with molybdenum disulfide nanosheets and carbon coating layers (MXene/

Microwave‐Actuated CuS/CuCo2O4 Heterojunction Microneedles for Synergistic Eradication of Deep‐Seated Biofilms and Inflammatory Microenvironment Remodeling in Acne Treatment

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Deep skin infections and dense biofilm barriers caused by Propionibacterium acnes (P. acnes) remain significant challenges in recurrent acne vulgaris, exacerbated by the poor stratum corneum penetration of conventional therapies and rising antibiotic resistance.

Hollow Microsphere‐Modified Asymmetric Multilayer Nanocomposites With Low Reflectivity and High Electromagnetic Shielding Performance

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Electromagnetic interference (EMI) shielding materials with low reflectivity are ideal materials for addressing the pollution caused by electromagnetic radiation. Ti3C2Tx MXene is widely used for EMI shielding due to its excellent conductivity.

Large Cation‐Induced Lattice Distortion in Carbon‐Based High‐Entropy Oxides: Spin‐State Engineering and Broadband Microwave Absorption

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT High‐entropy oxides (HEOs) are promising for microwave absorption but suffer from a trade‐off between impedance matching and attenuation, often requiring high filling ratios (> 50 wt%). Herein, we propose a “lattice‐spin” dual‐regulation strategy by introducing giant‐radius Bi into a single‐phase HEO solid solution.

微波预处理焦化废水有机组分的GC-MS分析

open access: yesGongye shui chuli, 2015
采用微波辐射的方法对某焦化厂的焦化废水原水进行降解,考察了废水的pH、初始浓度、微波辐射的时间和功率对去除COD的影响。试验结果表明:pH=9、微波功率800 W、微波辐射4 min时,COD去除率最高达到29%。在此条件下,对焦化废水进行微波处理,用气相色谱-质谱联用仪(GC-MS)分析微波处理前后焦化废水中有机物组分的变化情况。结果表明,焦化废水经微波预处理后含氮杂环及其他多环有机物减少,而易生物降解的苯酚类单环有机物增多,其可生化性得到改善。
