Copper Tantalate by a Sodium-Driven Flux-Mediated Synthesis for Photoelectrochemical CO Reduction.

Small Methods

January 2025

Liquid Sunlight Alliance, Lawrence Berkeley National Laboratory, 1 Cyclotron Rd, Berkeley, CA, 94720, United States.

Copper-tantalate, CuTaO (CTO), shows significant promise as an efficient photocathode for multi-carbon compounds (C) production through photoelectrochemical (PEC) CO reduction, owing to its suitable energy bands and catalytic surface. However, synthesizing CTO poses a significant challenge due to its metastable nature and thermal instability. In this study, this challenge is addressed by employing a flux-mediated synthesis technique using a sodium-based flux to create sodium-doped CTO (Na-CTO) thin films, providing enhanced nucleation and stabilization for the CTO phase.

Department of Biomedical Science & Institute of Bioscience and Biotechnology, Kangwon National University, Chuncheon, 24341, Republic of Korea.

Immune cells show enormous potential for targeted nanoparticle delivery due to their intrinsic tumor-homing skills. However, the immune cells can internalize the nanoparticles, leading to cellular functional impairments, degradation of the nanoparticles, and delayed release of drugs from the immune cells. To address these issues, this study introduces an approach for the synthesis of freshly derived neutrophils (NUs)-based nanocarriers system where the NUs are surfaced by dialdehyde alginate-coated self-assembled micelles loaded with mitoxantrone (MIT) and indocyanine green (ICG) (i.

Organic dyes play a crucial role in live-cell imaging because of their advantageous properties, such as photostability and high brightness. Here we introduce a super-photostable and bright organic dye, Phoenix Fluor 555 (PF555), which exhibits an order-of-magnitude longer photobleaching lifetime than conventional organic dyes without the requirement of any anti-photobleaching additives. PF555 is an asymmetric cyanine structure in which, on one side, the indole in the conventional Cyanine-3 is substituted with 3-oxo-quinoline.

Dust removal on solar panels of exploration rovers using Chladni patterns.

Sci Rep

January 2025

Department of Aeronautical and Astronautical Engineering, Korea Aerospace University, Goyang, 10540, Republic of Korea.

The buildup of dust on solar panels has significantly reduced the operational lifespan and mission performance of exploration rovers, and traditional dust removal techniques have proven inadequate for the Martian environment. The present study proposes a novel method for removing dust from the solar panels of Mars exploration rovers using Chladni patterns, addressing the persistent issue of efficiency loss due to Martian dust accumulation. To overcome these challenges, the proposed method leveraged Chladni patterns, generated by specific frequencies, to effectively clear dust from the panels.
