Intermediate-regulated dynamic restructuring at Ag-Cu biphasic interface enables selective CO electroreduction to C fuels.

A bimetallic heterostructure has been shown effective to enhance the multi-carbon (C) product selectivity in CO electroreduction. Clarifying the interfacial structure under electrolysis and its decisive role in the pathway selection are crucial, yet challenging. Here, we conceive a well-defined Ag-Cu biphasic heterostructure to understand the interfacial structure-steered product selectivity: The Cu-rich interface prefers ethylene, while the dominant product switch to alcohols with an increasing Ag fraction, and finally to CO as Ag occupying the main surface.

Regulating socketed geometry of nanoparticles on perovskite oxide supports for enhanced stability in oxidation reactions.

Heterogeneous catalysts with highly dispersed active particles on supports often face stability challenges during high-temperature industrial applications. The ex-solution strategy, which involves in situ extrusion of metals to form socketed particles, shows potential for addressing this stability issue. However, a deeper understanding of the relationship between the socketed geometry of these partially embedded nanoparticles and their catalytic performance is still lacking.

Despite advancements in molecular profiling, the mechanisms driving GC proliferation and metastasis remain unclear. This study identifies Early 2 Factor 4 (E2F4) as a key transcription factor that promotes GC cell proliferation, migration, and invasion by upregulating DNA Replication and Sister Chromatid Cohesion 1 (DSCC1) expression.

Agreement of lymphocyte subsets detection permits reference intervals transference between flow cytometry systems: direct validation using established reference intervals.

Objectives: With the increasing demand and application of lymphocyte subsets detection in clinical laboratories, different single-platform flow cytometer (FCM) systems have been developed. There is an urgent need to establish the reference intervals (RIs) for different single-platform FCMs and transferring them from one FCM system to another provides a much more feasible and convenient approach. This study aimed to explore the transferability of RIs for lymphocyte subsets across different flow cytometry platforms.

Enhanced Catalytic Oxidation Reactivity over Atomically Dispersed Pt/CeO Catalysts by CO Activation.

The elevation of the low-temperature oxidation activity for Pt/CeO catalysts is challenging to meet the increasingly stringent requirements for effectively eliminating carbon monoxide (CO) from automobile exhaust. Although reducing activation is a facile strategy for boosting reactivity, past research has mainly concentrated on applying H as the reductant, ignoring the reduction capabilities of CO itself, a prevalent component of automobile exhaust. Herein, atomically dispersed Pt/CeO was fabricated and activated by CO, which could lower the 90% conversion temperature () by 256 °C and achieve a 20-fold higher CO consumption rate at 200 °C.
