Article Abstract

The addition of an extra metal source induces the transformation from crystalline α-Ni(OH) to an amorphous NiCoFeCrMo-based high-entropy hydroxide (HEH) and maximizes the high-valence Ni content in HEH. For OER electrocatalysis, the quinary HEH possesses an overpotential of 292 mV at 10 mA cm, a Tafel slope of 54.31 mV dec and the boosted intrinsic activity, surpassing other subsystems.

RuO, the benchmark catalyst for the oxygen evolution reaction (OER), has traditionally been considered Pauli paramagnetic; however, recent findings have demonstrated its antiferromagnetic (AFM) properties, hinting at the opportunity to enhance RuO's OER performance by manipulating its magnetic traits. In this study, we successfully induced weak ferromagnetism in commercial RuO, transitioning it from an AFM state using an electrochemical sodiation method. This process resulted in high activity, achieving an overpotential of 145 mV to reach 10 mA cm and extending the service hours by more than 13 times compared to pristine RuO in 0.

Reduced mitochondrial quality and quantity in tumors is associated with dedifferentiation and increased malignancy. However, it remains unclear how to restore mitochondrial quantity and quality in tumors and whether mitochondrial restoration can drive tumor differentiation. Our study shows that restoring mitochondrial function using retinoic acid (RA) to boost mitochondrial biogenesis and a mitochondrial uncoupler to enhance respiration synergistically drives neuroblastoma differentiation and inhibits proliferation.

Enhancing singlet oxygen generation for photosensitizers in aqueous media can markedly improve the efficacy of photochemical therapy. Herein, triblock polymers composed of pyropheophorbide a photosensitizer (PPa), polyethylene glycol, and phospholipid are synthesized. These triblock polymers, driven by hydrophilic-hydrophobic interactions, spontaneously fold into an amphiphilic structure and further self-assemble into nanomicelles.

Hydrogen peroxide (HO) is a key signaling molecule in tumor progression, making its real-time detection vital for elucidating the complex mechanisms underlying tumorigenesis. Herein, we report a rationally colorimetric sensing platform for rapid tumor screening, leveraging the bifunctional enzyme-like activity of a heterostructured h-NiO/CoO/C nanosphere. Notably, by activating electron structure reconstruction with abundant oxygen vacancies and utilizing a dual-non-precious-metal method, h-NiO/CoO/C nanosphere enhances catalytic performance beyond the limitations of single-non-precious-metal-doped nanomaterials (e.

A precise modulation of heterogeneous catalysts in structural and surface properties promises the development of more sustainable advanced oxidation water purification technologies. However, the poor catalyst stability due to covering of surface-active sites by oxidation intermediates remains a key bottleneck to their practical applications. Herein we propose a simple defect-induced in-situ single-atom anchoring strategy to overcome this challenge by creating unique asymmetric active-sites on the catalyst surface.
