Anion-Directed Assembly of a Bimetallic Pd/Ag Nanocluster: Synthesis, Characterization, and HER Activity.

Palladium-doped silver nanoclusters (NCs) have been highlighted for their unique physicochemical properties and potential applications in catalysis, optics, and electronics. Anion-directed synthesis offers a powerful route to control the morphology and properties of these NCs. Herein, we report a novel Pd-doped Ag NC, [Pd(H)Ag(S){SP(OPr)}] (), synthesized through the inclusion of sulfide and hydride anions.

Robotic-Assisted Colon Cancer Surgery: Faster Recovery and Less Pain Compared to Laparoscopy in a Retrospective Propensity-Matched Study.

: Colorectal cancer (CRC) is the third most common cancer worldwide, with colon cancer accounting for approximately 60% of all CRC cases. Surgery remains the primary and most effective treatment. Robotic-assisted surgery (RAS) has emerged as a promising approach for colon cancer resection.

Stable Field Emissions from Zirconium Carbide Nanoneedle Electron Source.

In this study, a single zirconium carbide (ZrC) nanoneedle structure oriented in the <100> direction was fabricated by a dual-beam focused ion beam (FIB-SEM) system, and its field emission characteristics and emission current stability were evaluated. Benefiting from controlled fabrication with real-time observation, the ZrC nanoneedle has a smooth surface and a tip with a radius of curvature smaller than 20 nm and a length greater than 2 μm. Due to its low work function and well-controlled morphology, the ZrC nanoneedle emitter, positioned in a high-vacuum chamber, was able to generate a single and collimated electron beam with a current of 1.

Functioning performance trajectory and its associated factors for people with disability-A 4-year national study.

Background: Humans experience functioning difficulties in daily life, which are dependent on the interaction between health conditions and barriers in life. In general, functioning is an umbrella term and a dynamic concept. Thus, identifying the factors associated with long-term functioning would be beneficial to the development of specific health policies and quality of life for people with disabilities.

Hydride-containing Ag- and Au-rich 8-electron superatomic icosahedral cores: a DFT investigation.

Following several reports on ligand-protected atom-precise nanoclusters which encapsulate hydrides as interstitial dopants within their icosahedral core, the stability, structure and bonding of MH@Ag and MH@Au (M = Mo-Ag; W-Au) 8-electron cores is investigated through DFT calculations. The encapsulation of up to = 3 hydrides appears to be possible but at the cost of substantial structural distortions. In most of the computed models, the hydrides are found nearly free to move inside their icosahedral cages.
