Biomaterial design strategies for enhancing mitochondrial transplantation therapy

BMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...

Carrier‐free self‐assembled nanomedicine for combination‐therapy of acute myeloid leukemia

BMEMat, EarlyView.
CPDS combines drugs with three different mechanisms of action to achieve a multi‐mechanism combination therapy for AML by directly killing tumor cells and activating anti‐tumor immunity. Abstract As the main acute myeloid leukemia (AML) clinical treatment, the chemotherapy alone cannot meet the clinical therapeutic needs due to the high heterogeneity ...

Selective Oxidation Strategies for Cost‐Efficient Green Hydrogen Production via Hybrid Water Electrolysis

Carbon Energy, EarlyView.
Hybrid water electrolysis has emerged as a promising alternative to conventional electrolysis for sustainable hydrogen production. The economic potential of replacing water oxidation with organic substrates is assessed. For each substrate, representative electrocatalysts and mechanistic insights are reviewed to identify design principles for optimized ...

Rhodium-Catalyzed Oxidative Annulation of Hydrazines with Alkynes Using a Nitrobenzene Oxidant

, 2016
Rhodium-catalyzed oxidative annulation of hydrazines with alkynes has been accomplished using 1,3-dinitrobenzene as an oxidant. A variety of hydrazines with alkynes were converted to 1-aminoindole derivatives in good to high yields.

Efficient and Durable Sulfion Oxidation Coupled With Hydrogen Production via Cu@Cu2S Heterostructured Nanowires

Carbon Energy, EarlyView.
We present a facile and liquid‐phase approach to synthesize Cu@Cu2S core‐shell heterostructure nanowires derived from copper nanowires at room temperature for robust sulfide oxidation reaction (SOR)‐assisted H2 generation. The Cu@Cu2S core‐shell heterostructure nanowires exhibit superior SOR activity with an ultralow potential of 0.3 V (vs.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

Chemistry – A European Journal, EarlyView.
ABSTRACT The development of synthetic procedures for preparing metal nanoparticles with controlled size using sunlight opens new avenues toward more sustainable methods with lower energy consumption. Herein, we propose the use of double‐vacancy halide perovskites as precursors for engineering highly crystalline and small platinum nanoparticles (< 3 nm)
