Quenching induced Cu and F co-doping multi-dimensional CoO with modulated electronic structures and rich oxygen vacancy as excellent oxygen evolution reaction electrocatalyst.

The development of highly efficient non-precious electrocatalysts for the oxygen evolution reaction (OER) remains a significant challenge. In this work, we introduce a highly effective OER electrocatalyst, Cu-F-CoO, synthesized by doping copper (Cu) and fluorine (F) into CoO using a quenching method. Both experimental and theoretical calculations reveal that Cu and F incorporation significantly shifts the d-band center closer to the Fermi level, creates abundant oxygen vacancies, and facilitates the reconstruction of the catalyst to form the CuCoOF/CuO heterojunction.

Calcium peroxide functionalized mesoporous polydopamine nanoparticles triggered calcium overload for synergistic tumor gas/photothermal therapy.

Cancer remains a significant global health challenge due to its high mortality rates and the limitations of conventional therapies, which are often associated with severe side effects and limited efficacy. Calcium (Ca) overload therapy has emerged as a promising strategy for inducing tumor cell apoptosis. However, existing methods that rely on direct Ca delivery often face limited efficacy due to tumor adaptation mechanisms.

Exquisitely designed (0 0 1) active face of BiOCO based on BiOBr/g-CN layers with multi-channel charge transfer for efficient purification of organic water pollutants under visible light.

The design of heterojunction and active crystal face is an effective way to promote the separation and migration of photogenerated charge in the process of photocatalytic reaction. In this work, the band gap intercalation BiOBr/BiOCO/g-CN (BBC) ternary photocatalyst was successfully designed by one step hydrothermal method. It is found that under alkaline conditions, the addition of g-CN to BiOBr leads to the preferential growth of the (0 0 1) crystal face of the third phase BiOCO, and the (0 0 1) crystal face is the active crystal face of the photocatalytic reaction.

High-entropy doping in NASICON cathodes: Activating the V/V redox couple and inducing a reversible single solid-solution phase reaction for advanced sodium ion batteries.

NaV(PO) (NVP) with typical NASICON structure is highly regarded as one of the most appealing cathodes for sodium-ion batteries (SIBs) for their excellent structural stability; however, the poor electronic conductivity and irreversible phase transition at high voltage (∼4 V) for the material result in poor rate capabilities and significant capacity degradation during electrochemical reactions. Herein, the high-entropy doping strategy of introducing six types of metal ions into the V-sites in NaV(PO) is used to design a high-performance cathode of NaV(Mn, Ca, Mg, Al, Zr)Nb(PO) (HE-NVP) for SIBs. After the high-entropy doping, a reversible V/V redox pair is activated at high voltage of ∼4 V, which significantly contributes to the enhancement of energy density and operating voltage.

Electrolyte engineering via non-fluorinated solvent for high-performance lithium metal batteries.

Lithium metal batteries (LMBs) employing high-voltage cathode present a promising pathway toward high-energy-density energy storage systems. However, critical challenges have hindered their practical application, including lithium dendrite proliferation, unstable solid-electrolyte interphase (SEI), and limited oxidative stability of conventional 1,2-dimethoxyethane (DME)-based electrolytes. Herein, we rationally design a siloxane-based electrolyte system featuring enhanced oxidative stability through solvent molecular engineering.

Competitive adsorption and diffusion of methane and vapor-phase per- and polyfluoroalkyl substances in montmorillonite nano pores: Environmental implications.

Given the persistence, bioaccumulation, and potential health risks associated with PFAS, understanding their transport behavior in landfill gas barrier is of paramount importance. To gain a deeper understanding of the adsorption and diffusion behavior of vapor-phase PFAS in unsaturated, montmorillonite-rich clay barriers, a molecular dynamics simulation was conducted.

A green sulfidated micro zero-valent iron based-hydrogel for the synergistic removal of heavy metal cations and anions in groundwater.

The sulfur modification and incorporation of sodium alginate hydrogel facilitated the efficient and sustainable removal of both single and multi-heavy metals.

Droplet digital PCR-based single aptamer selection.

Aptamers are potent alternatives to antibodies in applications including diagnostics and disease treatment. These synthetic molecules are generated from sequences identified through specific targets within an aptamer pool of random sequences, approximately 10 in size, via the Systematic Evolution of Ligands by Exponential Enrichment (SELEX) process. Nevertheless, SELEX encompasses repetitive, time/money-consuming and stochastic methodologies.

Papillary thyroid carcinoma and strumal carcinoid transformations of a mature cystic teratoma with NRAS codon 61 mutation: A case report.

Mature cystic teratoma(MCT) is the most prevalent neoplasm derived from germ cells in females; its progression to malignancy is infrequent. The coexistence of papillary thyroid carcinoma(PTC) and strumal carcinoid derived from MCT is exceptionally rare. To the best of our knowledge, only six cases of this condition have been reported to date, however, the molecular information and immune cell infiltration for the mixture has never been studied.

Preparation, characterization of algae polyphenol-polysaccharide composite films and application in chilled porcine longissimus lumborum packaging.

The objective of this study was to assess the efficacy of pullulan (PUL) based films incorporated with algae polyphenol extracts (APE) in preserving the freshness of porcine longissimus lumborum (PLL) during refrigerated storage at 4 °C for 7 d.
