Time-dependent, species-specific effects of N:P stoichiometry on grassland plant growth [PDF]

, 2010
N and P have different eutrophication effects on grassland communities, yet the underlying mechanisms are poorly understood. To examine plant growth in response to the varying (relative) supply of N and P, we conducted a two-year greenhouse experiment ...

Ultrabroadband Chiral Emission from Cu Nanocluster Eggshell Membrane/CsPbBr3 QD Composites with a Cholesteric Superstructures

Advanced Functional Materials, EarlyView.
This study presents a novel wide‐bandwidth circularly polarized luminescence (CPL) system combining Cu nanoclusters, perovskite quantum dots, and cholesteric liquid crystals. The design achieves strong CPL emission across 480–750 nm (glum up to 1.31 at 514 nm and 1.46 at 620 nm). Using biomaterials and a simple structure, it offers a promising strategy

A Smart Bio‐Battery Facilitates Diabetic Bone Defect Repair Via Inducing Macrophage Reprogramming and Synergistically Modulating Bone Remodeling Coupling

Advanced Functional Materials, EarlyView.
This research presents a novel implantable bio‐battery, GF‐OsG, tailored for diabetic bone repair. GF‐OsG generates microcurrents in high‐glucose conditions to enhance vascularization, shift macrophages to the M2 phenotype, and regulate immune responses.

RANKL+ senescent cells under mechanical stress: a therapeutic target for orthodontic root resorption using senolytics

International Journal of Oral Science, 2023
In dentistry, orthodontic root resorption is a long-lasting issue with no effective treatment strategy, and its mechanisms, especially those related to senescent cells, remain largely unknown.

Synergistic Compatibilization of CsPbBr3 Perovskites and HfO2 Nanocrystals for Hybrid Sensitized Nanoscintillators

Advanced Functional Materials, EarlyView.
Lead halide perovskite nanocrystals are promising scintillators but suffer from reabsorption losses and limited compatibility with high‐Z additives. Hybridization of CsPbBr3 nanocrystals with PbBr2‐passivated HfO2 nanoparticle sensitizers, achieved during or after synthesis, produces stable composites with maintained optical quality, improved ...

Vibration‐Mediated Recovery of Irradiated Osteocytes and Their Regulatory Role in Breast Cancer Bone Metastasis

Advanced Healthcare Materials, EarlyView.
Radiotherapy damages bone and disrupts osteocyte function, yet mechanically mediated protection remains largely unexplored. This study demonstrates that low‐magnitude, high‐frequency (LMHF) vibration mitigates irradiated osteocyte apoptosis, restores their ability to regulate breast cancer extravasation, and acts synergistically with radiotherapy to ...
