Article Abstract
Fe single atom catalysts (SACs) with high coordination numbers have emerged as high-performance catalysts for the conversion of CO to CO. However, the influence of alkali cations at the catalyst-electrolyte interface has not yet been understood clearly. Here, we investigate the role of various alkali metal cations (Na, K, Rb) in catalytic CO reduction reaction (CORR) behavior on high coordination number Fe SACs (FeN and FeN) obtained from a facile hard template method. We find that larger cations can greatly promote the CORR and such effects are enhanced with increasing cation concentration. Nevertheless, the hydrogen evolution side reaction (HER) on co-existing N heteroatom sites will be worsened. This trade-off highlights the importance of manipulating the reactive sites for SACs. From theoretical simulation and spectroscopy results, we confirm that the functioning mechanism of cations on Fe SACs lies in the enhancement of the adsorption of key intermediates through direct coordination and indirect hydrogen bonding effects. With the rationally designed Fe SACs (FeN) and the electrolyte conditions (1 M KOH), our flow cell test demonstrates a maximum Faraday efficiency of CO (FE) of approximately 100% at 100 mA cm. This research provides significant insights for future SACs and electrolyte design.

We systematically evaluated the DNA adsorption and desorption efficiencies of several nanoparticles. Among them, titanium dioxide (TiO₂) nanoparticles (NPs), aluminum oxide (Al₂O₃) NPs, and zinc oxide (ZnO) NPs exhibited strong DNA-binding capacities under mild conditions. However, phosphate-mediated DNA displacement efficiencies varied considerably, with only TiO₂ NPs showing consistently superior performance.

Background: Comorbidities may affect incidence and management of cancers. The burden of comorbidities among AIAN cancer patients and survivors is unknown.
Methods: Using SEER-Medicare, we identified AIAN people aged 66+ years diagnosed with female breast, lung, and colorectal cancers (2000-2019), with at least one year of Medicare coverage prior to diagnosis.

Introduction: Health professionals may be susceptible to misusing alcohol due to stress and burnout. This is especially true in states with high alcohol consumption. Health care organizations can implement evidence-based policies, programs, and solutions that identify, address, and help prevent adverse outcomes and burnout for health workers.

Triple-negative breast cancer (TNBC) lacks expression of estrogen receptor (ER), progesterone receptor (PR), and HER2, and remains one of the most aggressive and therapeutically challenging breast cancer subtypes, marked by early relapse, metastasis, and limited targeted treatment options. In a recent study published in The Journal of Pathology, Kuo et al provide compelling evidence that nicotine exposure, whether from tobacco smoke or e-cigarette vapor, drives TNBC progression by promoting stem-like and metastatic phenotypes. Integrating clinical datasets, patient tissues, cell lines, and in vivo models, the authors demonstrate that nicotine enhances tumor aggressiveness via coordinated upregulation of CHRNA9 and IGF1R.

As a new generation of high-energy-density energy storage system, solid-state aluminum-ion batteries have attracted much attention. Nowadays polyethylene oxide (PEO)-based electrolytes have been initially applied to Lithium-ion batteries due to their flexible processing and good interfacial compatibility, their application in aluminum-ion batteries still faces problems. To overcome the limitations in aluminum-ion batteries-specifically, strong Al coordination suppressing ion dissociation, high room-temperature crystallinity, and inadequate mechanical strength-this study develops a blended polymer electrolyte (BPE) of polypropylene carbonate (PPC) and PEO.
