La3+ Vacancy Mediated Enhancement of Near‐Infrared Emission in Cr3+‐Activated La2MgTiO6 Phosphors for Multifunctional Applications

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Near‐infrared (NIR) phosphors with broadband and efficient emission are pivotal for the performance of NIR phosphor‐converted light emitting diodes (pc‐LEDs). In this study, the double perovskite phosphor La2MgTiO6:Cr3+ phosphor with broadband emission in the range of 650–950 nm was prepared.

Synergistic Enhancement of Toluene Catalytic Oxidation via Pt‐Induced Oxygen Vacancies and Heterojunction Built‐In Electric Field

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Improving catalytic activity for volatile organic compounds (VOCs) oxidation and enhancing water‐tolerance stability remain challenging in practical applications. Herein, a composite catalyst integrating Pt/CoOx‐NiOx mesoporous nanorods (MNRs) with a phenyltriethoxysilane (PhTES)‐modified surface was fabricated via a facile route for toluene ...

Ultrathin MnO2‐PEG‐PD‐L1 Nanosheets Enable Tumor Microenvironment Modulation and NIR‐II Photothermal Immunotherapy for Durable Control of Lung Cancer and Postoperative Recurrence

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Lung cancer is one of the most common and deadly malignancies worldwide. Although immune checkpoint inhibitors, including PD‐1/PD‐L1 blockers, have benefited a subset of patients, response rates remain limited, and recurrence is frequent because of the immunosuppressive tumor microenvironment (TME), characterized by hypoxia and dysregulated ...

Influence of alginate combined infrared intervention on ooze blood after PICC in patients with low platelet

open access: yesHuli yanjiu, 2016
[目的]探讨藻酸盐联合红外线干预血小板低下病人PICC置管后穿刺点渗血的效果。[方法]将135例血小板低下病人按置管先后顺序分为对照组、藻酸盐组、藻酸盐联合红外线组各45例。对照组覆盖穿刺点敷料用无菌纱布,藻酸盐组用藻酸盐敷料,藻酸盐联合红外线组红外线灯照射穿刺点后再用藻酸盐敷料。观察3组PICC置管后1周穿刺点渗血情况及敷料更换次数。[结果]藻酸盐联合红外线组渗血情况及敷料更换次数比较均明显低于对照组和藻酸盐组 ...

Titanium Implant Abutments With Polydopamine‐Mesoporous Cerium Dioxide Coatings for Enhanced Antibacterial, Anti‐Inflammatory, and Soft Tissue Integration Properties

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The poor soft tissue integration around titanium implants creates a microgap that serves as a pathway for pathogen invasion, resulting in infection, inflammation, and the progression of peri‐implantitis. As the implant’s transmucosal component, the abutment determines the degree of peri‐implant soft tissue attachment.

Enhancement of Corrosion and Wear Resistance in Polymeric Coatings via Ce(III)‐Functionalized Ternary ZnAlCe Layered Double Hydroxides Intercalated With EDTMP

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The intricate corrosion environment necessitates the polymeric coating's adaptability to the surroundings. In this work, the integration of rare‐earth Ce(III) ions and ethylene diamine tetramethylene phosphonic acid (EDTMP) in a layered double hydroxide (LDH) material is developed to enhance the corrosion protection and anti‐wear properties of

Differences in characteristics between naturalized threatened plants and other threatened plants

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.
